    ABSTRACT

    Understanding the factors that shape menstrual product choices is crucial for improving menstrual health and hygiene practices among young women in low-resource settings. This study investigates the influence of parental education, embarrassment, and sanitation facilities on the choice between hygienic menstrual products, like single-use pads, and unhygienic options, such as old clothes. A structured questionnaire was used to interview 366 nursing students in Bangladesh, with an average age of 23.3 ± 4.3 years. Descriptive statistics, Pearson's chi-square test, and multivariable logistic regression were performed using JMP Pro 17. The major products were single-use pads (61%) and old clothes (32%). Participants' family was the primary source of menstrual information, and product choices were influenced by both fathers' (p < 0.05) and mothers' (p < 0.05) education level. Additionally, the participants reported negative perceptions of the sanitation facilities, citing issues such as a lack of privacy, cleanliness, and the availability of water and soap. Embarrassment about buying (Adjusted Odds Ratio (AOR): 2.86 [1.16–7.07]) and privacy of bathroom facilities (AOR: 2.92 [1.12–7.63]) increased the odds of old clothes, while fear of staining blood (AOR: 2.95 [1.53–5.68]) increased the odds of having single-use pads. Better menstrual health and hygiene practices require improved parental education, reduced embarrassment, and better sanitation facilities.

    Sanitation facility conditions and waste disposal practices are hypothesized to affect the fecal contamination of drinking water and kitchenware. The present study aimed to examine the physical conditions of sanitation facilities and waste disposal locations as well as determine the concentrations of Escherichia coli in drinking water, cups, dishes, flies, toilet floors, and kitchen floors. A total of 336 samples were collected from 17 households in peri-urban Lusaka. Generalized linear mixed models showed that six out of seven physical pit-latrine conditions, waste disposal practices, and kitchen hygiene practices had significant effects on the contamination of either kitchenware or drinking water. The results highlighted that improving the physical pit-latrine conditions, dumpsite location, washing water, and kitchenware-drying location may potentially reduce fecal contamination of drinking water, cups, and dishes.

    Fecal contamination with a poor water, sanitation and hygiene environment in urban informal settlements poses diarrhea risks. Little information is available on the contamination of environmental media with enteric pathogens in such settlements. We investigated the contamination of Escherichia coli, rotavirus, and Cryptosporidium spp. in water, on kitchenware, and on flies in urban informal settlements of Chawama and Kanyama, Lusaka, Zambia. These environmental media were examined by XM-G agar cultivation for E. coli and specific real-time RT-PCR assays to detect rotavirus and Cryptosporidium spp. E. coli, rotavirus, and Cryptosporidium spp. were detected in samples of household stored drinking water (6 of 10 samples, 3 of 10 samples, and 2 of 10 samples, respectively), cups (10 of 20 samples, 2 of 13 samples, 1 of 13 samples, respectively), and flies (35 of 55 samples, 5 of 17 samples, 1 of 17 samples, respectively). The ranges of rotavirus concentrations in household stored drinking water, on cups, and flies were 2.9 x 10(2)-2.2 x 10(5) copies/L, 1.2 x 10(2)-4.3 x 10(2) copies/cup, and 2.0 x 10(1)-2.0 x 10(2) copies/fly, respectively. These results indicate the contribution of drinking water and kitchenware to enteric pathogen exposure and potential role of flies in microbial transmission.

    Abstract Children's faecal waste is a major environmental health issue despite increasing access to sanitation facilities and sanitary products in Indonesia. This cross-sectional study investigated child faecal management practice and disposable diaper usage among under-fives living in an urban slum of Indonesia. Data on household socio-demographics, child characteristics, and child faeces management practices were collected from 184 randomly selected pairs of mothers and children through interviews and observations. Findings revealed children's common defaecation sites as improved toilet, disposable diaper, and reusable diaper at 33.7, 33.2, and 16.3%, respectively. However, hygienic child faeces disposal was at 45%. Multivariate logistic regression indicated that the common use of disposable diapers and bathroom floor as the child's defaecation site increased unhygienic disposal. This prevalence decreased for mothers with higher education and those who had initiated toilet training. Promoting mothers' disposal of child faeces from disposable diapers, preventing child defaecation on the bathroom floor, and initiating toilet training as soon as a child can walk alone are thus potential interventions.

    Abstract Background Homo sapiens have experienced admixture many times in the last few thousand years. To examine how admixture affects local adaptation, we investigated genomes of modern Polynesians, who are shaped through admixture between Austronesian-speaking people from Southeast Asia (Asian-related ancestors) and indigenous people in Near Oceania (Papuan-related ancestors). Methods In this study local ancestry was estimated across the genome in Polynesians (23 Tongan subjects) to find the candidate regions of admixture-enabled selection contributed by Papuan-related ancestors. Results The mean proportion of Papuan-related ancestry across the Polynesian genome was estimated as 24.6% (SD = 8.63%), and two genomic regions, the extended major histocompatibility complex (xMHC) region on chromosome 6 and the ATP-binding cassette transporter sub-family C member 11 (ABCC11) gene on chromosome 16, showed proportions of Papuan-related ancestry more than 5 SD greater than the mean (> 67.8%). The coalescent simulation under the assumption of selective neutrality suggested that such signals of Papuan-related ancestry enrichment were caused by positive selection after admixture (false discovery rate = 0.045). The ABCC11 harbors a nonsynonymous SNP, rs17822931, which affects apocrine secretory cell function. The approximate Bayesian computation indicated that, in Polynesian ancestors, a strong positive selection (s = 0.0217) acted on the ancestral allele of rs17822931 derived from Papuan-related ancestors. Conclusions Our results suggest that admixture with Papuan-related ancestors contributed to the rapid local adaptation of Polynesian ancestors. Considering frequent admixture events in human evolution history, the acceleration of local adaptation through admixture should be a common event in humans.

    Water, sanitation and hygiene (WASH) factors are responsible for 11.4% of deaths in Zambia, making WASH a key public health concern. Despite annual waterborne disease outbreaks in the nation’s peri-urban (slum) settlements being linked to poor WASH, few studies have proactively analysed and conceptualised peri-urban WASH and its maintaining factors. Our study aimed to (a) establish residents’ definition of peri-urban WASH and their WASH priorities; and (b) use ecological theory to analyse the peri-urban WASH ecosystem, highlighting maintaining factors. Our study incorporated 16 young people (aged 17–24) residing in peri-urban Lusaka, Zambia in a photovoice exercise. Participants took photographs answering the framing question, ‘What is WASH in your community?’ Then, through contextualisation and basic codifying, participants told the stories of their photographs and made posters to summarise problems and WASH priorities. Participant contextualisation and codifying further underwent theoretical thematic analysis to pinpoint causal factors alongside key players, dissecting the peri-urban WASH ecosystem via the five-tier ecological theory ranging from intrapersonal to public policy levels. Via ecological theory, peri-urban WASH was defined as: (a) poor practice (intrapersonal, interpersonal); (b) a health hazard (community norm); (c) substandard and unregulated (public policy, organisational); and (d) offering hope for change (intrapersonal, interpersonal). Linked to these themes, participant findings revealed a community level gap, with public policy level standards, regulations and implementation having minimal impact on overall peri-urban WASH and public health due to shallow community engagement and poor acknowledgement of the WASH realities of high-density locations. Rather than a top-down approach, participants recommended increased government–resident collaboration, offering residents more ownership and empowerment for intervention, implementation and defending of preferred peri-urban WASH standards.

    Background: Adequate nutrition is required for growth and development in children. This study tested the effectiveness of nutrition education on knowledge and BMI-for-age (BFA) of school-aged children in the Kumasi Metropolis. Methods: Children, aged 9-13 years old were recruited from ten randomly selected primary schools in the Metropolis. The schools were randomly allocated into 3 groups: nutrition education (3 schools), physical activity (PA) education (3 schools), both interventions (2 schools), or control (2 schools). Following a baseline nutrition and PA knowledge and status assessment in 433 children, twice-monthly nutrition and PA education and demonstrations were carried out for 6 months, followed by a post-intervention assessment. Results: PA and nutrition knowledge improved in all groups (P<0.001); the highest improvement was among those who received both interventions (31.0%), followed by the nutrition education group (29.8%), and the least, the control group (19.1%). Overall, BFA improved by +0.36, from baseline (-0.26) to end of the intervention (+0.10, P<0.001). Within the groups, the nutrition group (+0.65, P<.001) had the highest improvement, then, both the intervention group (+0.27, P<0.001), the PA group (+0.23, P<0.001) and lastly, the control group (+0.18, P=0.001). Conclusion: Nutrition education could improve knowledge and BMI-for-age in school-aged children in Ghana.

    Abstract Background Growth references (growth charts) are used to assess the nutritional and growth status of children. In developed countries, there are growth charts based on the country’s national surveys. However, many developing countries do not have their own growth references, so they usually use WHO and US CDC references. In such cases, it is known that the growth statuses of the subject are underestimated or overestimated. This study sought to accurately assess the growth status of children by developing a local growth chart for children living in the Southern Province of Zambia. Methods Anthropometric measurements were conducted on 1135 children aged 2–19 years in the target area. The height and weight data for each sex and age were smoothed using the LMS method, and a percentile curve of height and weight was developed. Based on the US CDC reference, three indicators of undernutrition (stunting, underweight, and thinness) were calculated to determine the proportion of those who are undernourished (z-score < − 2). Results The 50th percentile curve of height and weight in the growth chart of the target population was equivalent to the 5–25th percentile curve of the US reference, and the children of Zambia were both small and of low weight. Conversely, although many subjects are small and of low weight, it was found that there were few poor nutritional statuses as judged by BMI. Through comparison with a previous study in the Southern Province of Zambia, a secular change in the growth of children over 20 years was found. Although there was no significant increase in height and weight in the older age group, there was a significant increase in height and weight at an earlier age. This is thought to be due to an increase in the growth rate of children due to improved socioeconomic conditions, women’s education level, and improvement in health care standards. Conclusions The subjects were small and of low weight compared to the US population, but the nutritional status was not poor by BMI. The height and weight at an earlier age increased compared to 20 years ago.

    BACKGROUND: Low back pain (LBP) is a major problem; it causes significant burden, incurs considerable economic and human costs, and adversely affects the quality of life (QoL). Central sensitivity syndrome (CSS) is known as a group of overlapping conditions that share a common pathophysiological mechanism of central sensitization. Previous studies have shown that CSS is present in several disorders. However, it has been studied for people with presurgical LBP. The purpose of the study was to investigate the proportion of patients with CSS for presurgical LBP and to analyse the association of CSS with clinical symptoms and psychological factors. METHODS: Data of demographics, the central sensitization inventory (CSI), psychological measures, clinical symptoms of 238 patients with presurgical LBP were evaluated. The patients were divided into two groups depending on the CSI scores (≥40 and < 40). The two groups were compared, and the correlation between the CSI scores and other outcomes was analysed. Furthermore, multiple regression analysis was performed to identify factors contributing to the CSI scores. RESULTS: 13.0% of participants were CSS. All outcomes were significantly different between the groups and significant associations were found between the CSI scores and all other outcomes. In addition, Pain Catastrophizing Scale (PCS) was most significant associated scale for the CSI scores. CONCLUSION: We found that certain patients had CSS with presurgical LBP. The CSI scores were significantly associated with the majority of the factors. The PCS was the factor with the most influence on the CSI scores.

    Abstract Background Good nutrition and physical activity of school-aged children are important for ensuring optimum growth and reducing obesity. This present study assessed associations between breakfast consumption, BMI-for-Age (BMI) and physical fitness in a cross-section of school-aged children attending government-owned primary schools in Kumasi, Ghana. Method The sample consisted of 438 pupils (boys = 213; girls = 225; mean age 11.1 ± 1.1), attending 10 randomly selected schools. Weight (kg), height (cm) and Mid Upper Arm Circumference (MUAC) were measured for each participant, and BMI-for-age z-scores determined using the World Health Organisation (WHO) anthroplus software. Participants were stratified into thinness, normal weight, overweight/obese using WHO cut offs. Physical fitness was assessed using forward jump, left and right handgrips, flexibility, sit-ups and 50 metre run following standard procedures and converted to scores of 1 to 10 following Japanese standards, based on which percentiles were derived. Total fitness score for each pupil was computed by adding all scores. A questionnaire was used to assess meal intake patterns. Results The mean BMI-for-age z-score for participants was − 0.24 ± 0.99. Thinness, normal weight and overweight/obesity were 2.7, 86.5, and 10.5% respectively among the pupils. Overweight was higher in girls (14.2%) compared to boys (4.2%), p = 0.003. Similarly, mean MUAC was significantly (p = 0.021) higher in the girls (22.0 ± 3.2 cm) than the boys (20.7 ± 7.3 cm). For physical fitness, the girls scored higher in forward jump (p < 0.0001), 50-m run (p = 0.002) and overall fitness score than the boys (21.0 ± 6.2 versus 19.2 ± 8.3, p = 0.012). However, a larger proportion of boys performed excellently and poorly than girls (p = 0.019). A positive correlation was observed between BMI z-score and hand grip (r = 0.21, p < 0.001), while sit up (r = − 0.11, p = 0.018) showed a negative correlation with BMI z-score. No other fitness test varied by BMI. Overweight children performed best in handgrip. Majority of children said they engaged in exercise (89.9%) and consumed breakfast (78.9%). Breakfast consumption was not associated with BMI z-score (x2 0.0359, p = 0.549) but non-breakfast consumers performed better in 50 m run compared to consumers (7.0 seconds ± 2.3 vrs 6.3 seconds ± 2.5, p = 0.022). Children who reported to exercise were physically fitter than those who did not. Conclusion Underweight levels were low while overweight was over 10% in these children. Girls were more than 3 times affected by overweight than boys, and were also physically fitter than boys. Breakfast consumption was not related to weight or fitness.

    The aim of the present study was to evaluate whether an exercise intervention, nutrition education, or the combination of both were effective in weight reduction and maintenance for rural school children. Two hundred twenty-nine primary school children aged 9 to 12 years determined as overweight/obese were randomly assigned to 1 of 4 groups: exercise intervention, nutrition education, combination of both, and control. Nutrition education and rope-skipping sessions were performed for 2 months. Anthropometric measurements were administered at baseline, after 2 months (postintervention), and 1 year later (follow-up). The order of change from high to low in the body mass index standard deviation scores (BMI-SDS) between postintervention and baseline was combined intervention, exercise intervention, and nutrition education. The BMI-SDS between following-up and baseline was for combined intervention, exercise intervention, and nutrition education. The combined intervention had the best short-term and long-term effects. The exercise intervention had a better short-term effect than nutrition education, while nutrition education had a better long-term effect than the exercise intervention.

    Background: Maternal and child undernutrition is an important issue, particularly in low-and middle-income countries. Children at high risk of malnutrition should be prioritized to receive necessary interventions to minimize such risk. Several risk factors have been proposed; however, until now, there has been no appropriate evaluation method to identify these children. In sub-Saharan Africa, children commonly receive regular check-ups from community health workers. A simple and easy nutrition assessment method is therefore needed for use by semi-professional health workers. Objectives: The aim of this study was to develop and test a practical screening tool for community use in predicting growth stunting in children under two years in rural Zambia. Methods: Field research was conducted from July to August 2014 in Southern Province, Zambia. Two hundred and sixty-four mother-child pairs participated in the study. Anthropometric measurements were performed on all children and mothers, and all mothers were interviewed. Risk factors for the screening test were estimated by using least absolute shrinkage and selection operator analysis. After re-evaluating all participants using the new screening tool, a receiver operating characteristic curve was drawn to set the cut-off value. Sensitivity and specificity were also calculated. Results: The screening tool included age, weight-for-age Z-score status, birth weight, feeding status, history of sibling death, multiple birth, and maternal education level. The total score ranged from 0 to 22, and the cut-off value was eight. Sensitivity and specificity were 0.963 and 0.697 respectively. Conclusions: A screening tool was developed to predict children at high risk of malnutrition living in Zambia. Further longitudinal studies are needed to confirm the test's validity in detecting future stunting and to investigate the effectiveness of malnutrition treatment.

    We collected anthropometric data (height and weight) and calculated the body mass index (BMI [kg/m2]) of 89preschool children, aged 3 years (range, 36-47 months), who were living in a rural area of Hokkaido, in order to evaluatetheir growth and nutritional status. On average, the children had normal BMI; only 3% of children (n=3) or 1%of children (n=1) were classified as "obese" or "underweight", respectively. The obesity screening methods used—"obesity rates" and "BMI percentile"—had 99% agreement (only 1 child was classified differently), suggesting thateither method is accurate for the evaluation of overweight in preschool children.

    This study was conducted to clarify nutritional status and associated factors in 5-24 month old children in the district of Batouri, Republic of Cameroon. Mothers were interviewed using a semistructured questionnaire, and the child's weight, length, head circumference, and mid-upper arm circumference was collected. The data were compared with child growth standards proposed by the World Health Organization using Z-scores; (2)-test, Fisher's exact test, and Wilcoxon rank sum test were used to determine variables associated with malnutrition. A total of 100 mother-child pairs participated in this study; valid data from 100 pairs were subjected to analysis. The percentages of children with malnutrition indicators were wasting (6%), stunting (31%), underweight (14%), and low mid-upper arm circumference (16%). Five factors were found to be statistically significant in their association with the children's malnutrition: mother's age, child's age, mother's educational level, mothers who had family planning information, and the source of tap water. A high percentage of stunting was positively associated with a high percentage of chronic malnutrition. We speculate that insufficient nutrition was more likely to begin after weaning.

    Objective/Background The degree of a patient's absorption in tasks as a measure of rehabilitation effectiveness has yet to be studied. The objective of this study is to develop a scale that can measure a patient's flow state in a clinical situation such as occupational therapy (OT). Methods The final 14 items were determined from the comprehensive assessment of item analysis results by a preliminary experiment. A total of 240 participants engaged in computer games that induced three psychological states: flow, anxiety, and boredom. After performing each task, participants completed our flow scale and the State-Trait Anxiety Inventory (STAI). The reliability was calculated using Cronbach's alpha coefficient. The validity was confirmed from three viewpoints, namely, the correlation coefficient with the STAI, the discrimination power of each psychological state, and the accuracy of factor structure. An occupational analysis of various activities was also conducted to confirm that the computer game task was representative of measurable activities. Results Cronbach's alpha coefficient was.918. The total score of the scale was significantly negatively correlated with the total score of STAI (r = -.537, p < .01). A significant difference among each psychological state was observed (p < .01). Covariance structure analysis indicated that the model fit index showed an acceptable fit. The computer game task used in this experiment was closely related to games, crafts, learning, cooking, and playing an instrument. Conclusion Our flow scale appears to have satisfactory reliability and validity to verify quantitatively whether the occupational tasks used in OT can effectively provide a flow experience for patients.

    Objective:Obesity is a growing health concern in the Oceanic populations. To investigate the genetic factors associated with adult obesity in the Oceanic populations, the association of single nucleotide polymorphisms (SNPs) of the beta-2 adrenergic receptor (ADRB2) gene with obesity was examined in 694 adults living in Tonga and Solomon Islands.Results:A screening for variation in 16 Oceanic subjects detected 17 SNPs in the entire region of ADRB2, of which nine SNPs including two non-synonymous ones, rs1042713 (Arg16Gly) and rs1042714 (Gln27Glu), were further genotyped for all subjects. The rs34623097-A allele, at a SNP located upstream of ADRB2, showed the strongest association with risk for obesity in a logistic regression analysis adjusted for age, sex, and population (P=5.6 × 10-4, odds ratio OR=2.5, 95% confidence interval CI=1.5-4.2). The 27Glu was also significantly associated with obesity in the single-point association analysis (P=0.013, OR=2.0, 95%CI=1.2-3.4) however, this association was no longer significant after adjustment for rs34623097 since these SNPs were in linkage disequilibrium with each other. A copy of the obesity-risk allele, rs34623097-A, led to a 1.6 kg/m2 increase in body mass index (BMI defined as weight in kilograms divided by height in meters squared) (P=0.0019). A luciferase reporter assay indicated that rs34623097-A reduced the transcriptional activity of the luciferase reporter gene by approximately 10% compared with rs34623097-G. An electrophoretic mobility shift assay demonstrated that rs34623097 modulated the binding affinity with nuclear factors. An evolutionary analysis implies that a G> A mutation at rs34623097 occurred in the Neandertal genome and then the rs34623097-A allele flowed into the ancestors of present-day humans.Conclusion:The present results suggest that rs34623097-A, which would lead to lower expression of ADRB2, contributes to the onset of obesity in the Oceanic populations. © 2013 Macmillan Publishers Limited.

    Aim: Uncoupling protein (UCP) genes, which may contribute to energy metabolism in mitochondria, may be involved in the pathogenesis of obesity. We analyzed the differences in energy expenditure between single nucleotide polymorphisms (SNPs) UCP3 - 55C/T , UCP3 Y210Y , and UCP2 A55V among Indonesian children. Methods: The study included 76 schoolchildren (36 obese and 40 healthy mean age, 12.8 years) in Semarang, Indonesia. Body composition was measured by bioelectrical impedance analysis resting energy expenditure (REE) by indirect calorimetry physical activity by uniaxial accelero meter and total energy expenditure (TEE) by the equations extrapolated from REE and physical activity. UCP3-55C/T , UCP3 Y210Y , and UCP2 A55V were examined by restriction length fragment polymorphism analysis. Results: The TEE of the subjects with the T/T genotype at UCP3-55C/T after adjusting for fat-free mass (63.2 ± 7.2 kcal/ kg/day) and T/T at UCP2 A55V (62.8 ± 5.6 kcal/kg/day) was lower than that of the subjects with the C/C and C/T genotypes (p < 0.05). The REE of the subjects with these T/T geno types tended to be lower than that of the subjects with C/C and C/T (p = 0.05). No significant differences in REE or TEE were found between the UCP3 Y210Y genotypes. Conclusions: The subjects with the T/T genotypes of UCP3-55C/T or UCP2 A55V had lower TEE than those with other genotypes.

    Introduction: Many studies have been carried out to reveal the mechanism of the short stature of Pygmy hunter-gatherers in the African rainforest. However, due to limitations concerning age-estimation, sample collecting and data analysis, their complete growth pattern has not yet been clarified. Aims: This study has three aims as below (1) to develop a smoothed growth curve, (2) to elucidate the presence of adolescent growth spurt and (3) to assess the correlation of growth pattern factors to their final short stature. Subjects and methods: Anthropometric measurements including height and weight were carried out for 626 Baka children in southeast Cameroon. LMS method and Preece-Baines function were adopted to develop a smoothed growth curve and to assess their growth pattern. Results: The height velocity curve and acceleration curve derived from the LMS method showed the presence of an adolescent growth spurt. Biological parameters indicated their spurt was extremely weak and started at nearly the same time as published populations. Height gains between take-off and final height were almost equal between Baka children and children in published populations. Conclusion: The presence of a weak adolescent growth spurt is suggested in the growth pattern of Pygmy hunter-gatherers. Moreover, their short adult stature is possibly related to growth rate before onset of puberty. © Informa UK, Ltd.

    Our objectives were to (1) compare the measured and predicted resting energy expenditure (REE) using 18 equations in normal-weight and obese adolescents, and (2) examine potential predictive factors for accurately estimating REE in obese adolescents. The subjects chosen were 41 obese and 35 normal-weight adolescents living in an urban area in Indonesia. REE was measured using indirect calorimetry and compared with predicted REE determined via 18 equations. New predictive equations were developed via stepwise multiple regression analysis. Mean differences between the predicted and measured REE were within ± 5% with 13 equations tested in normal-weight subjects, and only six equations in obese subjects. New predicted REE derived from our new equations was significantly correlated with measured REE (P < 0.0001, R2 = 0.50.7). Measured REE was overestimated by existing predictive equations, especially in obese subjects. New predictive equations need to be developed that take age, climate and ethnicity into account, in addition to physical characteristics. © 2011 Informa UK, Ltd.
  • Addressing the wild yam question: How Baka hunter-gatherers acted and lived during two controlled foraging trips in the tropical rainforest of southeastern Cameroon

    We designed observational surveys of controlled foraging trips of Baka hunter-gatherers in Cameroon to verify the 'wild yam question'-i.e. is it possible for human beings to live without agricultural products in a tropical rainforest?-and to examine their foraging lifestyle. We observed two 20-day trips during which no agricultural or commercial food except salt and pepper could be used. The first trip was conducted by six married couples in August, the short dry season, of the year 2003, and the second one by eight married couples in October, the rainy season, 2005. The Baka cooperators obtained 22 species and 43 vernacular names of food in all during both survey periods. No cooperators lost weight from any food shortage in both seasons. Energy intake per consumption-day was estimated at 2528-2865 kilocalories in the dry season, and at 2479-2777 kilocalories in the rainy season. Providing more than 60% of estimated energy intake in both seasons, wild yam tubers proved to be an essential food to enable a foraging life in tropical rainforests. From this survey we could find no evidence that it is impossible to live independently of agriculture in a tropical rainforest although it seemed that the cooperators paid a high energy cost to secure food, especially wild yam tubers. This study implies that a Paleolithic foraging lifestyle in the African tropical rainforest was very likely, although not easy, and that Paleolithic foragers may have been the ancestors of the present 'pygmy' hunter-gatherers. © 2012 The Anthropological Society of Nippon.

    Objectives: This study examined the association between the serum leptin level and body mass index (BMI) and the effects of urbanization and polymorphisms of leptin (LEP) or leptin receptor (LEPR) genes on the leptin level in three Solomon Islands populations. Methods: A Melanesian population living in a remote area (participants: 106 males and 106 females, ages: 18-74 years), a Melanesian population in an urban area (89 and 94, 18-79 years), and a Micronesian population who migrated to a peri-urban area in the 1960s (84 and 69, 18-71 years) were studied. Anthropometric and serum leptin measurements and genotyping for LEP G-2548A and LEPR K109R and Q223R were performed. Results: The prevalence of obesity (BMI ≥ 30 kg/m2) was the highest in the Micronesian population (30.1%), followed by the urban (18.6%) and the rural (2.4%) Melanesian population. The serum leptin concentration was the highest in the urban Melanesian, followed by the Micronesian and the rural Melanesian populations (P < 0.05). Interestingly, the parameter coefficients of the leptin concentrations on the BMIs were nearly identical in the urban and rural Melanesians after adjusting for age and gender. The LEPR 223Q/Q genotype was associated with an increased leptin level only in the Micronesian population after adjusting for BMI (P = 0.0008 and 0.0016 referenced to the Q/R and the R/R types, respectively). Conclusions: These observations suggest that the increase in obesity in the Micronesians had a genetic component while that in Melanesians might have been related with the urbanization. © 2010 Wiley-Liss, Inc.

    This paper analyzes the time required for recovery from a shock and the factors affecting the speed of recovery, because existing literature on consumption smoothing has not paid much attention to the recovery of consumption. Using household monthly panel data collected in Southern Province of Zambia, this paper estimates consumption growth functions and examines the impact of heavy rainfall shock that took place in December 2007. It is found that households with more livestock assets recovered consumption in the long-rum (i.e. after one and a half year) or they are resilient, while those with less livestock assets did not recover.

    Various Pacific Island populations have experienced a marked increase in the prevalence of obesity in past decades. This study examined the association of a promoter polymorphism of the leptin gene (LEP), G-2548A (rs7799039), and two non-synonymous single nucleotide polymorphisms of the leptin receptor gene (LEPR), K109R (rs1137100) and Q223R (rs1137101), with body weight, body mass index (BMI) and obesity (BMI ≥ 30) in Pacific Islanders. A total of 745 Austronesian (AN)-speaking participants were analyzed after adjusting for age, gender, and population differences. The results revealed that carriers of the 223Q alleles of LEPR had significantly higher body weight (P = 0.0009) and BMI (P = 0.0022) than non-carriers (i.e., 223R homozygotes) furthermore, the 223Q carriers also had a significantly higher risk of obesity in comparison to non-carriers (P = 0.0222). The other two polymorphisms, G-2548A and K109R, were associated with neither body weight, BMI, nor obesity. The 223Q allele was widely found among the AN-speaking study subjects, thus suggesting that the LEPR Q223R polymorphism is one of the factors contributing to the high prevalence of obesity in the Pacific Island populations. © 2009 Springer-Verlag.

    Objective Previous studies on the association between physical activity (PA) and neighborhood environments (NE) focused on either objectively measuring the NE or the residents? perception of NE. Here, we investigate which actual or perceived NE is associated with residents? PA in Japan. Methods Two regions with an objectively assessed high and low residential density, land use mix-diversity, and street connectivity, respectively, were identified in one city. The subjects were selected using a stratified random sampling method by sex and age in each region. The NE of the subjects was objectively measured using the Geographic Information System (GIS), and the subjects? perception of the NE was assessed using a questionnaire. The daily total number of walking steps was measured with an accelerometer, and walking and cycling time were assessed by a questionnaire. Results For the female subjects, the mean cycling time, subjectively assessed as a means of transport, was signifi- cantly longer in the group with a high GIS score for the number of land use types, while the score for total number of walking steps was significantly higher among those who were aware of places to walk to, and cycling time for transport was longer for those who perceived an accessibility to post offices, banks/credit unions, gymnasiums/fitness facilities, and amusement facilities in their neighborhood. For the male subjects, the score for walking time for leisure was longer for those who perceived aesthetics and an accessibility to parks, and the score for total walking steps was significantly higher for those who perceived an accessibility to bookstores or rental video stores in their neighborhood. Conclusions The results to this study demonstrate that daily PA was high among female subjects living in a NE with land use mix-diversity, and who had an awareness of places to walk to and the accessibility to facilities for daily necessities in their neighborhood. For male subjects, daily PA was high among those who perceived the aesthetics of and accessibility to facilities for pleasure in their neighborhood. Further research is needed to determine the association between PA and NE on the basis of sex differences. © 2009 The Japanese Society for Hygiene.

    The nutritional status, growth, and health of children are useful indicators for assessing the ability of a population to adapt to the environment and the extent of this adaptation. These indicators can be used to measure and evaluate the overall nutritional status and health of young children. In Zambia, in southern Africa, drought and unpredictable erratic rainfall are major factors affecting the health and nutrition of the inhabitants, particularly small children. A recent national survey conducted in Zambia indicated that the nutritional status of children was poor because 50% of children between 3 and 59 months of age had stunted growth (extremely short for their age), 20% were underweight (low weight for their age), and 6% showed growth wasting (low weight for their height). By contrast, between 1991 and 2004, data from six cross-sectional national surveys did not show any evidence of effects of drought. Therefore, an intensive, village-level, longitudinal monitoring survey is required to assess the effects of drought on the growth and nutrition of children. We briefl y summarize the growth and nutrition of Zambian children using data from the report of the Living Conditions Monitoring Survey (LCMS) 2004, with special focus on the southern and eastern provinces of Zambia. In addition, we propose a methodology for conducting a longitudinal survey to monitor child growth and nutrition in rural villages in the eastern and southern provinces of Zambia and report a 1-week intensive program to train local health assistants to make anthropometric measurements.

    It has been suggested that Neel's "thrifty genotype" model may account for high body weights in some Oceanic populations, which presumably arose in modern times. In European populations, common variants (rs1421085-C, rs17817449-G, and rs9939609-A) in the fat mass and obesity (FTO associated) were recently found to be associated with body mass index (BMI) or obesity. In this study, we investigated the population frequencies of these variants in six Oceanic populations (Melanesians, Micronesians, and Polynesians) and tested for an association with BMI. Unlike European populations, the Oceanic populations displayed no significant association between the FTO polymorphisms and BMI. These variants were in strong linkage disequilibrium. The population frequencies ranged between 4.2 and 30.3% in the six Oceanic populations, and were similar to those in southeast and east Asian populations. Our study of the FTO polymorphisms has generated no evidence to support the thrifty genotype hypothesis for Oceanic populations. © 2007 The Japan Society of Human Genetics and Springer.

    Physical activity in childhood is important as it may establish adult behavior. However, few studies on physical activity in children have been conducted, especially in Asian children. We performed anthropometric measurements of 159 school children in two grades (grade 5: 10-11 years old and grade 8: 13-14 years old) from urban areas of Korea (n=79) and China (n=80). The total daily energy expenditure (TEE) was estimated for 7 consecutive days using an accelerometer. The mean height, weight, and body mass index (BMI) for boys and girls in both countries exceeded the US national reference median (CDC, 2000). Physical activity levels (PALs) were significantly higher in the grade 5 group (10-11 years old) and in girls than in boys for both grades. No significant difference in PALs or daily step-counts (STPs) was observed between 'normal' and 'overweight' subgroups based on BMI, although negative correlations were found between weight, BMI, or %body fat vs. PAL or STP among Korean girls and Chinese boys (r=0.32-0.38, all p<0.05). Daily variation in physical activity was observed in Korean children. In the Koreans (boys and girls, both grades pooled), TEE and STP were significantly lower than the 7-day average on Sundays, whereas for the Chinese population, STP did not clearly differ between the weekends and the week averages. In summary, PALs were higher in the fifth grade boys and girls than in the eighth grade children; interestingly, girls tended to have higher PALs than boys. Daily variation in physical activity was observed in Korea; children were less active on Sundays.

    Sumo wrestling is unique in combat sport, and in all of sport. We examined the maximum aerobic capacity and body composition of sumo wrestlers and compared them to untrained controls. We also compared "aerobic muscle quality", meaning VO2max normalized to predicted skeletal muscle mass (SMM) (VO2max /SMM), between sumo wrestlers and controls and among previously published data for male athletes from combat, aerobic, and power sports. Sumo wrestlers, compared to untrained controls, had greater (p < 0.05) body mass (mean ± SD; 117.0 ± 4.9 vs. 56.1 ± 9.8 kg), percent fat (24.0 ± 1.4 vs. 13.3 ± 4.5), fat-free mass (88.9 ± 4.2 vs. 48.4 ± 6.8 kg), predicted SMM (48.2 ± 2.9 vs. 20.6 ± 4.7 kg) and absolute VO2max (3.6 ± 1.3 vs. 2.5 ± 0.7 L·min(-1)). Mean VO2max /SMM (ml·kg SMM(-1)·min(-1)) was significantly different (p < 0.05) among aerobic athletes (164.8 ± 18.3), combat athletes (which was not different from untrained controls; 131.4 ± 9.3 and 128.6 ± 13.6, respectively), power athletes (96.5 ± 5.3), and sumo wrestlers (71.4 ± 5.3). There was a strong negative correlation (r = - 0.75) between percent body fat and VO2max /SMM (p < 0.05). We conclude that sumo wrestlers have some of the largest percent body fat and fat-free mass and the lowest "aerobic muscle quality "(VO2max /SMM), both in combat sport and compared to aerobic and power sport athletes. Additionally, it appears from analysis of the relationship between SMM and absolute VO2max for all sports that there is a "ceiling "at which increases in SMM do not result in additional increases in absolute VO2max. Key PointsSumo wrestlers have a high absolute VO2max compared to untrained controls.However, sumo wrestlers have a low VO2max /kg of skeletal muscle mass compared to other combat sports, other strength/power sports, and untrained controls.The reason for this is unknown, but is probably related to alterations in sumo skeletal muscle compared to other sports.Based on the present and previous data, there appears to be a "ceiling "at which increases in skeletal muscle mass do not result in additional increases in absolute VO2max.

    This study investigates variation in body growth (cross-sectional height and weight velocity) among a sample of 22 small-scale societies. Considerable variation in growth exists among hunter-gatherers that overlaps heavily with growth trajectories present in groups focusing more on horticulture. Intergroup variation tends to track environmental conditions, with societies under more favorable conditions displaying faster growth and earlier puberty. In addition, faster/earlier development in females is correlated with higher mortality. For example, African "Pygmies," Philippine "Negritos," and the Hiwi of Venezuela are characterized by relatively fast child-juvenile growth for their adult body size (used as a proxy for energetic availability). In these societies, subadult survival is low, and puberty, menarche, and first reproduction are relatively early (given their adult body size), suggesting selective pressure for accelerated development in the face of higher mortality. In sum, the origin and maintenance of different human ontogenies may quire explanations invoking both environmental constraints and selective pressures. © 2006 Wiley-Liss, Inc.

    We designed an observational survey of the "pure" foraging lifestyle of the Baka hunter-gatherers in Cameroon to verify the "Wild Yam Question": is it possible for human beings to live without agricultural products in a tropical rainforest? The nutritional status, the type and amount of food procured and food-getting activity over 20 consecutive days in the forest camp were observed for six married couples in August, the short dry season, 2003. The subjects didn't loose weight and they finished the twenty-day foraging life without health problems. The energy contained in the food procured during the study period was estimated at 2732 kilocalories per person per day, which could be sufficient for the energy requirements of fairly small subjects. Fifty-three percents of this energy was from wild yam tubers, 26 percents from game meat, and 13 percents from wild nuts. The collection of wild yam tubers was stable during the study period. There was no significant difference in the amount of each food type procured between the first half of the study period and the latter half except for nuts, the amount of which increased in the latter half. As for the cost of unit food energy, neither the number of daily steps walked measured with pedometers nor the time for food-getting activities changed between the first half and the latter half of the study period. There was no evidence in this study that it was difficult to live independently of agriculture in a tropical rainforest.

    Pacific Islands populations can be broadly divided into Austronesians (AN) and Non-Austronesians (NAN); obesity and type 2 diabetes are prevalent in the former, although leptin levels in both groups have seldom been investigated. Thirty-seven (20 male and 17 female) adult pairs, matched by age and percent body fat, from AN-speaking Balopa and NAN-speaking Huli, all of whom migrated to settle in Port Moresby, the capital of Papua New Guinea, were selected for comparison of their serum leptin concentrations. The Balopa did not differ significantly from the HuIi in age (30.5 ± 9.7 and 30.0 ± 8.7 years for males, 33.7 ± 8.9 and 34.1 ± 7.5 years for females, respectively) or percent body fat (19.4 ± 5.6 and 18.8 ± 4.6 for males, 34.1 ± 6.2 and 33.3 ± 5.0 for females), although the BMI of females was lower in the Balopa (26.4 ± .9) than in the Huli (29.7 ± 4.7) (P = 0.02). In both ethnic groups, females had markedly higher leptin concentrations than males, but there was no significant inter-group difference in males (3.5 ± 2.6 and 3.1 ± 4.7 ng/ml, P = 0.14) or females (22.7 ± 12.9 and 19.7 ± 11.9 ng/ml, P = 0.40), after controlling for lifestyle factors and serum lipids.

    Background: Despite much concern about adult obesity among Pacific Islanders, childhood obesity has seldom been investigated. Aim: Based on the anthropometry of Tongan children aged 5-19 years, this study aims to elucidate age and sex differences in obesity prevalence calculated from BMI and its relation to body fat estimated by skinfold thicknesses. Subjects and methods: 895 students, aged 5-19 years, in the most modernized island and a remote island, were measured for stature, body weight, circumferences at waist, hip and mid-upper arm, and skinfold thicknesses at biceps, triceps and subscapular. The prevalence of overweight and obesity was calculated using the reference data of the International Obesity Task Force (IOTF) and the Centers for Disease Control and Prevention (CDC). Results: The prevalence of obesity of Tongan adolescent girls defined by the IOTF and CDC references was 19.4% and 22.8%, respectively, being considerably higher than that of not only juvenile girls but also adolescent boys. Among adolescents, the girls' BMI was positively correlated with fat mass whereas in boys it was not. The sex difference in adolescents was parallel to that in adults, being attributable to gender differences in daily behavioural patterns. Conclusions: Among Tongan adolescents, obesity prevalence in girls was much higher than in boys, in association with fat accumulation in the former. © 2005 Taylor & Francis.

    Seasonality of nutrient intake was evaluated by 7-successive-day food consumption survey in the ordinary season (March) and the slack season (June) of fish catch among 13 married couples in a Solomon Islands society, who were engaged in traditional horticulture and fishing, together with time allocation study. Males' time spent in gardening and fishing was significantly shorter in June than in March (gardening: -48 min/d, and fishing: -43 min/d; P<0 .05, respectively), while there was no seasonal difference in females. On the other hand, males spent more time in hunting and marketing, and females in particular did more time in marketing (P<0.01). No significant difference in energy intake between March and June was observed for either sex. The protein intake was significantly lower in June than in March (males: -23.9 g/d, P<0.01; females: -12.0 g/d, P<0.05). The males' fat intake was significantly higher in June than in March (+14.8 g/d, P<0.05), thought not significantly in females. To compensate the smaller amount of fish catch in June, the villagers spent more time in hunting and marketing, and they took larger amounts of coconut and a kind of nut, which abounds with fat . This study thus suggested that changes in food obtaining activities and food intake patterns of the villagers played significant roles to cope with seasonal shortage of fish catch.

    Time spent on subsistence activities was compared between rural sedentes and urban migrants of the Huli population in Papua New Guinea. Person-day observation data were collected for rural sedentes (441) in the Tari basin and for urban migrants in Port Moresby (175). The time spent on subsistence activities by males was longer in the urban area than in rural areas, while that by females was similar in both areas. Conspicuous gender inequality with respect to labour hours in rural areas seems to diminish when people move to urban areas, reflecting the different subsistence regime between rural and urban environments.

    Basal metabolic rate (BMR) and energy expenditure at rest and during step-tests were measured among urban migrants of Papua New Guinea Highlanders (n=6, 3 males and 3 females). Total energy expenditure (TEE) was assessed by heart-rate (HR) monitoring (flex-HR method) and physical activity level (PAL) calculation was based on BMR (i, e. PAL=TEE/BMR). All males had relatively higher PAL (above 2.0), whereas PAL of females varied (range, 1.51-1.96). These high PALS observed in males may reflect that they performed unusual heavy task (carpentry) during survey period. In addition, evaluation of accelerometers for the assessment of TEE was conducted by using TEE estimated from HR monitoring as reference . It was found that the TEE estimated from the accelerometer counts was highly correlated with that estimated from HR monitoring (r=0.85, p<0.05). The results suggest that the acceleration monitoring is a useful method for assessing physical activity of free-living populations.

    The influence of urbanisation on physical activity and dietary changes was examined in a Papua New Guinea Highland population. Adult male and female subjects (n 56) were selected, including twenty-seven rural villagers and twenty-nine urban migrants. BMR was calculated from values measured in similar samples of Huli-speaking population, according to gender and body weight. Total daily energy expenditure (TEE) was assessed by 24 h heart rate (HR) monitoring (flex-HR method) and physical activity level (PAL) calculation was based on BMR. Energy, protein and fat intakes were measured by weighing food on a single day. Urban subjects were heavier and taller than their rural counterparts significant differences were found in stature in men (P < 0.05) and body weight in women (P < 0.05). Urban subjects had longer sedentary periods (HR ≤ flex-HR) and shorter active periods (HR > flex-HR) than rural subjects. Consequently, the former had lower TEE and PAL than the latter significant differences were found in women (TEE, P < 0.05, PAL, P < 0.01) but not in men. Total daily energy intake and TEE were well balanced (< 7 %) in all groups, whereas protein and fat intakes were considerably higher in urban subjects than rural subjects. Reduced PAL and increased fat intake by urban dwellers may increase the risks of obesity and chronic degenerative diseases.

    Several studies on human energetics have been conducted in developed and developing countries, but very few simultaneously measured time use and energy expenditure. Only a few quantitatively compared subsistence patterns between rural and urban dwellers of an identical population. Here we present the daily physical activity level (PAL), physical exertion, time, and energy expenditure in contrasting subsistence/occupational activities of Papua New Guinea Highlanders, comparing 27 rural villagers (15 men, 12 women) who maintained traditional subsistence agriculture, with 29 urban migrants (14 men, 15 women) who engaged in cash-earning work. A large sex inequality in the division of labor was noted between rural males and females, but not among urban dwellers. Rural-urban comparison indicated sex differences in urbanization. For urban men, the reduction of physical exertion level during work, from energy-consuming agricultural work to sedentary cash-earning work, together with significantly extended work time (by 261 min/day, P < 0.001), led to an increase in work energy expenditure (15-29% of PAL). In contrast, urban women who spent almost equal time at work relative to rural women showed a lower energy expenditure (18% compared to 26% of PAL). The associations with urbanization included a gain in body weight (by 6.4 kg for either sex) and reduced PAL (by 7%, not significant in men 13%, P < 0.01 in women). Further research is needed to elucidate the effects of urbanization on time use, energy expenditure, and PAL, by comparing rural residents with urban migrants in the same population. © 2001 Wiley-Liss, Inc.

    The nutritional status of 75 male and 73female pygmy hunter-gatheres were surveyed as well as the daily physical activity, energy and intake of major nutrients, and total energy expenditure were examined for two married couples of the Baka hunter-gatherers in Cameroon. The average stature was intermediate relative to other Pygmy hunter-gatherers, and the subjects were generally well nourished. Despite the limited sample size and survey duration, the results indicated that the energy intake and energy expenditure of Cameroonian Baka hunter-gatherers were relatively low, which may enable them to adapt to low food availability in the village camps during the rainy season.

    Objective: (1) To evaluate inter-individual variations, regional and sex differences in the basal metabolic rate (BMR) and related variables (2) to compare measured BMR with estimated BMR using predictive equations and (3) to examine the net mechanical efficiency (NME) in step tests. Design: BMR and energy costs at rest and during step tests were measured by the Douglas bag technique of indirect calorimetry. NME was calculated from BMR and energy costs of step tests. Setting: Rural villages under subsistence agriculture and urban settlements under cash economy. Subjects: Adult males and females (n=33) including 16 rural villages and 17 urban migrants. Interventions: Step exercise test. Results: There were significant regional differences in BMR (per body weight) in both sexes. The BMR predicted by Schofield equation correlated with the measured BMR ( - 1 to + 3%), while the BMR predicted by Henry and Rees equations under estimated the measured BMR by 6 - 11%. NME was higher in urban subjects with larger body size than in rural subjects for both sexes, albeit insignificantly. NME tended to be higher with increased stepping level in both sexes. Conclusions: Urban migrants had lower BMR than rural dwellers, and the BMR predicted by Schofield equation correlated with the measured BMR in both sub-groups.

    Objectives: The study aimed to (1) elucidate the energetic adaptations of Huli people by comparing the three sub-populations in relation to their diversified natural and socioeconomic environment, based on energy expenditure and time allocation data and (2) assess the applicability of a new index of physical exertion levels of activities (physical exertion index: PEI). Research design and methods: Married males and females (n = 43) were selected, including 14 from a hilly village, 13 from a flat swampy village and 16 migrants to a town. Continuous heart rate (HR) monitoring, in conjunction with minute-by-minute observation of activities, was undertaken. Total energy expenditure was assessed by flex-HR method and physical activity level (PAL) was calculated as multiples of basal metabolic rate. Observed activities were divided into 15 categories and the PEI was calculated for each: PEI = (mean HR of a categorized activity)/(flex HR) x 100. Results: No significant difference was found in PAL among the three sub-populations: 1.77, 1.92 and 1.81 for men and 1.78, 1.98 and 1.66 for women in hilly and flat villages, and a town, respectively. The comparison of the two village groups revealed that hilly terrain did not affect substantially the physical intensity of agricultural activities. On the other hand, the town migrants were engaged in sedentary paid jobs and these were less energy consuming than agricultural work. However, the different energy costs between paid jobs and agricultural work were offset by longer work time in the town group than in the two village groups (251 vs 50 or 70 min in males 258 vs 152 or 138 min in females), resulting in similar PAL in the three groups. Conclusions: Despite contrasting natural and social environments, no significant difference was found in daily physical activity level among the three sub-populations (two villages and a town) of Huli-speaking people in Papua New Guinea Highlands.
  • Impact of population pressure on food production: An analysis of land use change and subsistence pattern in the Tari basin in Papua New Guinea Highlands

    The impact of increase in population on land use and subsistence pattern was examined in two environmentally contrasting Huli-speaking communities, Heli and Wenani, in the Tari basin in Papua New Guinea Highlands. Despite the similar extent of population increase in both communities, the damage to land differed markedly. In Heli, a decrease in land productivity owing to excessive agricultural use has induced farmers to shorten the fallow duration, which in turn has led to further land degradation and difficulties in increasing food production. In contrast, Wenani villagers have coped with the population increase by enlarging areas for cultivation and possibly will be able to double their present production level, although increasingly frequent disputes over land rights have restricted peoples' access to fertile areas. During a period of climatic perturbations in 1994, land and labor productivities of crops were three times higher in Wenani than in Heli, which suffered a severe food shortage. This difference in ability to cope with climatic perturbations may have increased with population growth. The findings in the present study suggest that the effects of population pressure on food production may differ between communities, depending on the indigenous environment and subsistence pattern.

    We chose two unplanned settlements (slums) from Lusaka, the capital of Zambia, and established a children's club in each site. The children's club members are comprised of youth and elementary school students. We conducted active-learning sessions on sanitation, safe drinking water and hygiene to youth and elementary school students with the help of local collaborators. The children’s club member (elementary school children and youth) conducted field surveys in their living environments (2 slums). The club held an exhibition where children and youth made presentations, and more than 200 people including their parents, residents, and politicians participated in the exhibition. A series of children's club activities (workshops, field surveys, presentations, etc.) were recorded as photos and videos by a local media artist (a collaborator). Currently we’re editing work. After the end, it will be widely available to the world on the Internet (project website, YouTube etc.).

    The aims of this study were to evaluate the nutrition status of, and clarify the maternal safe food preparation behaviors associated with malnutrition in, children aged <5 years in Cotonou, Benin. This study targeted 300 mother-child pairs visiting the University Hospital of Mother and Child Cotonou Lagoon. Mothers were interviewed using a structured questionnaire. Child height/length and weight measurements were determined and Z-scores were calculated using the WHO 2006 Child Growth Standards. On logistic regression analysis, significant variables on bivariate analysis, the associations of which were clarified in previous studies, were established as independent variables. Regarding nutrition status, 11.0% of the children had stunting and 14.7% were underweight. As a remarkable point, food refrigeration was statistically significant. It was suggested that the mother's safe food behaviors and the child malnutrition were related at weaning period.

    We developed a formula to estimate resting energy expenditure from cognitive function in elderly adults with dementia to aid in estimating energy requirements as the first step in developing a nutrition care plan. Semi-weighted dietary records from a 28-day period showed inadequate intake of dietary fiber, calcium, and zinc. After confirming a statistically significant correlation between quality of life (QOL) and dietary intake, we developed three okazu dango that can be used in various arrangements in advance meal preparation and are designed to provide supplemental nutrition, improve appetite, and promote eating independence. Composition analysis showed that the hardness,adhesiveness,and cohesiveness of these okazu dango fall under codes 3 and 4 of the Japanese Dysphagia Diet 2013 developed by the JSDR Dysphagia Diet Committee. The results of our nutrition intervention suggest that okazu dango reduce constipation and improve nutritional status and QOL in elderly adults with dementia.

    Physical activity is vital for a child's development but rapid motorization in Laos might have hindered it, increasing the risk of overweight/obesity. Our survey among 431 secondary school students in central Vientiane, the capital of Laos, revealed that only 9% of them achieved a recommended level of physical activity while 20% of them were overweight/obese. Those overweight/obese hold weight loss attempts but still remain physically inactive. No significant association was observed between perceived neighborhood environment and physical activity. Since physical activity is low but the prevalence of overweight/obesity is high among children in the city center of Laos, further public health efforts should be given to increase the level of their physical activity.

    Nutritional status, growth and physical fitness were evaluated for children of hunter-gatherers who lived in the African rainforest (Cameroon) and the South Pacific Islands (Papua New Guinea). Overall, the children had good nutritional status. Their daily travel distance increased with age, and inter-individual differences expanded when they grew to adolescents. This tendency was more pronounced in boys than in girls. Surprisingly, the mean daily step counts for the hunter-gatherer children was more than 20,000 steps for both boys and girls, which greatly exceeded the international standard. In other words, hunter-gatherer children walked considerably more than their counterparts living in modern societies. The results of physical fitness tests suggest that the test items widely used in our societies could underestimate the physical fitness of the hunter-gatherer children.

    We were able to add anthropometric data for infants and younger children of an African pygmy hunter-gatherer population to baseline data (N = 626), although it was difficult to conduct follow up measurements for the large sample due to their predominantly mobile lifestyle. Detailed observations on childcare revealed that children, particularly elderly girls spent longer time providing childcare than adults except for the infants’ mothers. Time allocation surveys further revealed that the daily travel (walking) distance and radius for children increased with age. For adolescents, individual variations of these variables expanded, especially in boys. The children had unexpectedly large step counts that exceeded 20,000 steps per day on average.

    1. 現代の狩猟採集民に関する定量データ収集： 昨年度に続き、ピグミー系狩猟採集民の子どものライフスタイルと健康にかんするフィールド調査を行った。森林キャンプにおける子どもの食物獲得活動に焦点を当てて、時間・量・栄養素（エネルギーとたんぱく質）の分析を行った。先行研究で言われてきた以上に、子どもたちは狩猟活動に長時間従事していたが、体格が完成途上であることと技術が乏しいため、栄養学的な貢献は小さいことが明らかとなった。さらに、乳児と養育者（母親、父親、祖父母、兄姉、その他の子ども、その他の成人）の育児活動についてチェックリストを用いた詳細な観察を行った。母親以外の育児協働者は、乳児1人1日あたり平均15.8人であり、大人・子ども、性別、親族関係を越えて多様であった。子どもの育児参加がみられ、とくに年長女子が育児活動に大きく貢献していた。
    2. ネアンデルタールの栄養生態とライフヒストリーに関する仮説の構築： 昨年度に提唱したネアンデルタールの身体成長のライフヒストリー仮説に脳の成熟の視点を加えて仮説を補強した。サピエンスの脳の成長（神経細胞の髄鞘化）は従来の予想よりもずっと遅く、20代中盤であることから、思春期の特徴（刺激、新奇性、リスク、仲間、社会的報酬に強く惹かれるといった思春期の特徴や思春期の問題行動はサピエンスに特徴的であり、ネアンデルタールには存在しなかった（弱かった）可能性が考えられる。同時にネアンデルタールは脳の柔軟性に乏しく、創造性も弱かったかもしれない。ネアンデルタールの1日のエネルギーバランスおよびロコモーション（歩行）のエネルギー効率について推論した。

    The current study observed Eskimos and Pygmy tribes who both practice hunting and gathering lifestyles. Several important aspects typical to those tribes who live closely to nature can be used as guidelines (and could possibly be beneficial) to Japanese children living in our modern society. “the experience of hunger” “the experience of a very simple lifestyle (with a minimum of possesions),” “life without a set schedule (i.e. wake up at sunrise)” “enduring harsh weather changes (hot and cold)” and “hunting for own food” are some of the habits that cause Eskimo and Pygmy children to be healthy while living in nature. Thus in order for children in Japan to stay healthy, the incorporation of daily recreation in nature is important.

    The Gidra people are a hunter-gatherer-cultivator tribe living in the low wetland that is located roughly in the center of the island of New Guinea and covers the southern coastal area near the Equator. The Gidra people, also called the Forest People, live in this tropical climate area by hunting game animals and gathering nuts in the tropical forests and the savannas, carrying out slash- and-burn agriculture by making use of the forests, fishing in the winding rivers and the web of tangled creeks, and growing sago palm (Metroxylon sagu) in the wetlands. Since the human ecological research has been continued from 1980, population data of the Gidra was obtained for deep analysis of the Gidra villagers. New method of investigation was tried on the group hunting with bows and arrows by using GPS meter and accelerometer. We obtained the detailed data of hunting activity for many hunters simultaneously: GPS location, moving direction and speed of each hunter.

    We conducted an integrated study for analyzing farmers' coping strategy and resilience of food security against climatic shocks in selected areas in Southern Zambia. Our empirical results suggest that weather index based cropinsurance expanded cropping area with earlier sowing period. Food Frequency Questionnaire (FFQ) revealed that the diet pattern of Zambian farm household members lack energy and animal protein intake. As for agricultural technology, alternative crops such as sweet potato increased food consumption levels when maize failed. Resilience mapping showed that small scale farmers are the least resilient. It is important to consider food security in comprehensive manner rather than focusing only on improving agricultural production. In order to build long-term resilience of rural households in Zambia, strengthening adaptive capacity by enhancing social safety net and improving infrastructure such as roads and communication, education, health/nutritional status are required.

    We developed evaluation methods for effects of environmental chemicals on the central nervous systems. First of all, the method for the quantification of DNA damage by chemicals in tissues and cultured cells was developed. Using the method, we evaluated apoptotic effects of diethyl phthalate parabens and a stevioside. Secondly, we developed an evaluation method for effects of chemicals on cell differentiation in PC12 cells. In addition, the evaluation method to detect apoptosis induced by metals and chelated metals was developed.

    Global nutritional assessment indicated that increases in the activities of daily life and dietary zinc uptake on the day of dialysis were important measures for maintainingimprovements in the nutritional status and quality of life (QOL) of hemodialysis patients; therefore, we developed a low-intensity exercise program (stretching and massage) to be undertaken during dialysis. This program, produced on an educational medium (DVD), provides a graded course that can meet the physical functioning and desire of the patientand can be performed at a comfortable self-pace. In addition, we devised a snack food for fortifying zinc levels to be taken after dialysis and developed a diet program based on motivational nutrition guidance. The results observed after the implementation of these programs indicate an amelioration of anemia and an increase power limb muscle mass in patients as well as an improvement in physical functioning.

    The purpose of these two studies was to investigate effects of health and environmental consciousness through lifestyle of the hunting and gathering society. I examined importance of environment and things in general for people in African rainforest(Pygmies) in 2009 and people in Alaskan Arctic(Eskimo) in 2010-2011 by using illustrations and pictures. Moreover, I was able to participate, observed and hear stories of how pygmies hunted and gathered in the forest and how Eskimos hunted caribous. It was theorized that their living styles are largely influenced in their values and consciousness of health and things.

    After the end of 6 years' "Ethnic Tension" between Guadalcanal and Malaita islanders in Solomon Islands, the life in suburban villages, which has been backward to subsistence economy during the tension, rapidly re-modernized and involved in market economy. In the present study, based on biannual surveys on health status, dietary habits and lifestyle of people in one such village, we clarified in which aspects such rapid change tended to appear and which aspects tended to be unchangeable, and we suggested the health transition model in the Solomon Islands.

    To verify the possibility of hunting-gathering life in the African tropical rainforest and to reveal its energetic balance we designed the observational surveys of controlled foraging trips in southeastern Cameroon. Gaining the eight couples cooperators of the Baka hunter-gatherers, we had two two-week trips, during which no-agricultural or commercial food could be used, in the forest near villages in August 2009, the minor dry season, and in April 2010, the minor rainy season where wild yam tubers were said to be scarcer. In spite of sever environmental condition, almost all cooperators kept their health and body weight during the both trips with the exception of a few cooperators who caught a cold. As to energy expenditure we are analyzing the data from the heart rate monitoring system.

    During 1980's and 90's, the East Tasimboko area of the Solomon Islands experienced rapid population growth and Westernization including frequent visit to Honiara, the capital city. There were three nearby clinics, where people easily obtained chloroquine and some other medicines so that mortality was decreasing. However, around 2000, the ethnic tension occurred in Guadalcanal Island, in which people fought between the two islands, Guadalcanal and Malaita. The tension changed everything. About 66% people lost their housings in East Tasimboko. People lost the transportation to Honiara due to the destruction of bridges and paved roads. Clinics were also broken so that availability of medicine was largely damaged. The present study aimed to clarify the effect of the ethnic tension on the health and life of the East Tasimboko residents. Mbambala area is made of 7 hamlets, which can be grouped into the two. In 4 hamlets, populations were naturally/socially increased, but in other 3 those unchanged or decreased due to move-out to other hamlets or high mortality probably caused by malaria. Urine diagnosis suggested overall improvement of health status. Considering the bimodal urine pH distribution in February 2006 and the fact that richer (and thus more obese) people suffered from more material effect, the change of health status can be judged as that some richer-obese people reduced energy intake due to the shortage of purchased food. However, in September 2006, urine pH distribution changed back to unimodal and most people took purchased staples more than once a day. WHOQOL-BREF showed moderate level of QOL, except that the scores of environmental domain were relatively lower than other domains. Immediately after the research in Sep. 2006, the transportation to Honiara has been re-established. It should make people's life drastically changed. Frequencies of going to Honiara were raised and cultivation of cash-crops like watermelon and shallot restarted. Some villagers started to store beer in their houses to sell them to other villagers. Frequency of eating purchased food increased. The WHOQOL-BREF in Sep. 2007 and Feb. 2008 clarified the drastic increase in the scores of environmental domain, which may reflect the re-establishment of regular transportation to Honiara. On the other hand, in Feb. 2008, the scores of social domain look decreasing. There is a possibility that psychological aftereffect of the Ethnic Tension has also disappeared. The prevalence of malaria seems to continuously decrease, amongst P. falciparum. Malaria positive individuals were not evenly distributed but converged into several households. The geographic/family effects should be further studied.

    The purpose of the study was to investigate whether neighborhood environments would correlate with residents' physical activity in Japan, and this study was the first trial of this kind in Japan. In the first year of this study, we analyzed previous studies and referred to related literature and papers. According to the results of previous studies, we concluded that the study region should be several different areas, environmental factors should be assessed by objectively and subjectively perceived measures, and multiple dimensions of physical activity such as transportation, leisure, etc. should be included. The Geographic Information System (GIS) was used to objectively assess the physical residential environment. We proposed the measurement methods and assessment items using GIS. Using the database of the these measurement methods and items, study subjects could be classified according to the individual neighborhood environments, such as residential density, connectivity of street and land use mix, etc. Also, an assessment method for the perceived environments of the residents was tested for reliability In this study, the Japanese version of the Abbreviated Neighborhood Environment Walkability Scale (ANEWS) was prepared. Thus, an international comparison study is feasible and will be conducted in the near future. The daily physical activity of the residents was objectively assessed by pedometer and accelerometer And a subjective method using the International Physical Activity Questionnaire (IPAQ) was also tested. To include different cultural and/or social regions in this study we selected different study areas a Tokyo metropolitan district and two local cities The study survey was conducted to delineate the association between neighborhood environments and residents' physical activity. The study results suggested that the neighborhood environment might influence residents' daily physical activity. However, the association between neighborhood environments and residents' physical activity was different depending on sex and region. Therefore, to promote physical activity, we concluded that the consideration of environmental factors unique to residents' neighborhood environments is needed. We proposed a new method using the three elements of location, time and physical activity, simultaneously. To assess these elements, GIS, accelerometer and small -sized Global Positioning System (GPS) were used. And we could integrate these three sources of data as a tool for assessing residents' individual behavior patterns. Now, we can clarify the characteristics of the association between neighborhood environments and physical activity. In the near future, we will present useful evidence for urban planning linked to residents' health behaviors.

    From 2003 to 2006,about 3,300 schoolchildren in Chunchon (Korea), Dalien (china), Taichung (Taiwan), Sapporo and Kitakyushu (Japan) were investigated on their 1) anthropometric measurements, 2) fitness and motor ability, 3) the resting metabolic rate by analyzing respirates, activity levels by attaching an accelerator and by the self-rating method, 4) energy intake, nutrition states and eating behavior by self-rating methods, 5) local tolerance to cold by a newly developed and convenient apparatus, 6) living environments, living time schedules, living behavior like using a computer by the questionnaire method, further more, the beginning of menarche and past allergy by the medical records of schools. Body height and body weight of schoolchildren in Chunchon, Dalien and Taichung increased rapidly, associated with the recent urbanization and changes in the life style, It is superior to those of schoolchildren in Japan where urbanization appeared earliest. As the increase in body weight was more marked than body height, BMI and percent body fat were in high levels. Obesity of schoolchildren in these cities is thought to be one of the health problems in many schools. Bone mineral density was higher in Kitakyushu and Taichung schoolchildren. Fitness and motor ability increased partly with physique enlargements, but some measurements were decreased with high BMI and percent body fat. Japanese schoolchildren showed good achievements in general. Physical conditions described above were compared with physical activity levels in daily living, dietary intake and dietary behavior. Many correlations were obvious between them. Females were more active than males in many cases other than in Japan. It coincided with physical characteristics between the sexes. Local tolerance to cold which may be decreased in the urbanize environment was related to morphologic characteristics and ways of daily living. Questionnaire data were summarized in a data base, and characteristics of living schedules and living environment of schoolchildren in each city were obvious.

    The aim of this research project is to elucidate the following questions : 1)" Could a tropical rainforest have been a habitat of human beings before the beginning of agriculture?" and 2)" If so, when did human beings inhabit it and what made it possible?" For this purpose we conducted two experimental studies on the foraging lifestyle of the Baka hunter-gatherers in Cameroon in August 2003 (dry season) and in October 2005 (rainy season). Furthermore, from a comparative viewpoint we did an observational study of the daily activity patterns of the same people in their village lifestyle in August 2004. At that time, we also measured the BMR (Basal Metabolic Rate) of about 60 Baka volunteers and the energy expenditure per minute in main daily activities of six married couples to estimate the total energy expenditure both in the foraging lifestyle and the village lifestyle. Although we have not finished analyzing our data yet, we can indicate the following points : 1)Though our experiments were limited in the research period of 20 days, in the seasons of dry August and rainy October, and in subject numbers of six to eight married couples, the possibility of a pure foraging lifestyle independent of agriculture in the African tropical rainforest was verified. 2)The main staple food was wild yams on which the Baka subjects depended for over 50 percent of their total food energy in both dry and rainy seasons. 3)Game meat, fish, nuts, honey, and termites were major complements to wild yams. We are also examining the cost : how much energy it costs to get food. After completion, we can compare the energy balance of a foraging lifestyle in a tropical rainforest with those in other environments and can evaluate tropical rainforests as a human habitat. In addition, we are preparing a first report on "Pygmy" hunter-gatherers' BMR which serves to elucidate what causes the "Pygmy" physical characteristics of small stature. We will present these papers on the above topics at CHAGS 10^ in India in December 2006.

    We examined the relationships between genetic characteristics and environmental factors associated with the risk factors for lifestyle-related diseases, such as obesity and diabetes, for six Austronesian populations on Oceanian islands. The target populations consisted of one from Tonga, two from Indonesia, and three from the Solomon Islands. Based on the mean body mass index(BMI), the Tongan population was judged ‘obese' and their waist-to-hip ratio tended to increase with age. Significant correlations were found between diabetic morbidity and indices of obesity, such as BMI and waist circumference. The results also suggested that abdomen fatness was a significant risk factor for abnormal glucose tolerance. By contrast, the mean BMI of the Indonesian populations was considerably lower than that of their Tongan counterparts, and they were categorized as ‘normal'. In the Indonesian populations, the fasting blood glucose was significantly correlated with blood pressure, while there was no significant relationship between diabetes and obesity indices. The populations of the three Solomon Islands consisted of two Melanesian groups that differed in their degree of modernization, and one group of Micronesian migrants from the Gilbert Islands (Kiribati). Their average BMI was higher than that of Indonesians, but lower than that of Tongans. Based on the BMI, men were categorized as ‘normal', and women as ‘overweight'. The urine dipstick test revealed that the Melanesian group with the low degree of modernization maintained a traditional diet (e.g., staple tubers, local greens, and fish). The results appear to reflect synergy between genetic characteristics and environmental factors, especially dietary patterns.
