English, Scientific journal, AIM: Our preconception care (PCC) initiative in Akita (Japan) was previously reported to improve health literacy and motivate behavioral changes. To make the check-up widely available, a more feasible and sustainable system is necessary. Our aim was to evaluate a resource-efficient preconception check-up implemented in Ehime Prefecture. METHODS: The Ehime PCC check-up included female employees aged 18-39 and took place between July 2023 and January 2024. Participants attended a lecture, underwent blood tests, and received written feedback. Pre- and post-intervention surveys were conducted for check-up evaluation. RESULTS: Fifty-nine women (median age: 31 years) participated. The results revealed that their health was inadequate for future pregnancies, with 23% exhibiting anemia (hemoglobin <12.0 g/dL) and 29% iron deficiency (serum ferritin <12 ng/mL). Furthermore, all participants had low 25-hydroxyvitamin D levels (<30 ng/mL). After receiving written feedback, 66% manifested an intention to improve their lifestyle, 21% an intention to consult an obstetrician and gynecologist, and 32% expressed a desire to become pregnant sooner. The proportion of those without intention to change their future behavior was significantly higher in Ehime (23.7%) compared to Akita (4.9%, p = 0.018). Recommendation ratings were significantly lower in Ehime (strongly recommend: 18.2% vs. 65.9%, p < 0.001), with more reporting anxiety (10.5% vs. 4.9%, p = 0.02). CONCLUSIONS: Preconception check-ups improved the intention to change behavior, even in resource-efficient settings. However, individual counseling may be more effective than written feedback in increasing the intention to change behavior and satisfaction. A resource-efficient feedback method that effectively motivates behavioral change and improves satisfaction is required. - Physical activity, sedentary time, and sperm DNA fragmentation index in healthy Japanese men

English, Scientific journal, PURPOSE: Twenty five years have passed since the first national survey on erectile dysfunction (ED) in Japan. The Japanese Society for Sexual Medicine conducted a nationwide survey on the actual status of sexual function targeting men over 20 years old in Japan using validated questionnaires commonly used in clinical practice. MATERIALS AND METHODS: Japanese men aged 20 to 79 years participated in our online epidemiological study on sexual dysfunction. Erectile status was assessed by direct questioning and specific questionnaires. Risk factors and frequencies of sexual intercourse, masturbation, nocturnal erections, and feeling sexual desire were assessed. The prevalence of these risk factors was compared between men with and without ED. Prevalence and frequencies were calculated for each 5-year age group. Main outcomes were the prevalence and number of patients with ED and simultaneous evaluation of age-related variations. RESULTS: Direct questioning of the men revealed that 13.0% felt troubled by ED. Although 81.0% of them had at least some ED symptoms based on a Sexual Health Inventory For Men score of ≤21, the prevalence of men with ED by Erection Hardness Score (EHS), the most appropriate questionnaire for Japanese with low sexual activity, was 30.9%, indicating that 14,012,596 men have ED. Most risk factors were related with ED, whereas frequencies of sexual intercourse, masturbation, nocturnal erections, and feeling sexual desire were affected by aging. However, the low frequency of these factors in the young generation was surprising. CONCLUSIONS: The EHS-based assessment revealed a prevalence of ED of 30.9%, which affected approximately 14 million men, and that the sexual desire, erection stiffness, orgasms, and satisfaction were lower than expected in young Japanese men, especially those aged 20 to 24 years, although those factors tended to worsen with aging. We believe that these findings actually reveal the current sexual status of men in Japan. - コロナ禍の自粛が及ぼす大学生の鬱症状への影響 第一波(R.2.5-6月)と第4波(R3.3-5月)時点におけるうつスコアの比較

Journal of occupational health, 29 Apr. 2024, [Peer-reviewed], [International Magazine]
English, Scientific journal, OBJECTIVES: Despite the recent increase in infertility and perinatal complications, preconception care is not commonly available in Japan. Working women are considered to have the greatest need for preconception care, as they increasingly marry and have children later in life. This study aimed to assess the feasibility and effectiveness of preconception check-ups in the workplace. METHODS: We provided 51 female employees aged 18-39 years with free preconception check-ups, including additional blood tests and an online medical questionnaire, during mandatory health check-ups at their workplace. A doctor provided online counselling based on the check-up results. We assessed fertility knowledge using the Cardiff Fertility Knowledge Scale (CFKS-J) and childbearing desire pre- and post-intervention. RESULTS: Preconception check-ups revealed various potential risk factors for future pregnancies, including underweight (12%), obesity (20%), Chlamydia trachomatis IgG antibody positivity (22%), low Rubella IgG antibody levels (47%), iron deficiency (12%), and 25-hydroxyvitamin D levels <30 ng/mL (98%). Post-intervention, the participants reported high satisfaction with the check-ups and significantly advanced their reproductive plans (P=0.008). Further, 95% of the participants indicated an intention to seek medical attention or make lifestyle changes. The post-intervention CFKS-J score (mean ± SD) was higher than the pre-intervention score (71.7 ± 19.3 versus 63.0 ± 22.0, P=0.006). CONCLUSIONS: We developed a preconception check-up package that can be integrated into workplace health examinations, complemented by tailored counselling. This novel check-up package is a feasible and effective approach for improving preconception health and fertility awareness. - Changes in menstrual symptoms and work productivity after checklist-based education for premenstrual syndrome: an 8-month follow-up of a single-arm study in Japan.

English, Scientific journal, BACKGROUND: Premenstrual syndrome (PMS) is prevalent among women of reproductive age, but most do not seek medical advice. We hypothesized that building PMS awareness could promote medical help-seeking for PMS and thus reduce menstrual symptoms and improve work productivity. METHODS: In January 2020, women aged between 25 and 44 years, having paid work, and not currently consulting with an obstetrics and gynecology doctor (n = 3090) responded to the Menstrual Distress Questionnaire (MDQ), the Premenstrual Symptoms screening tool, and the World Health Organisation Health and Work Performance Questionnaire. In addition, they received checklist-based online education for PMS. Of 3090 participants, 2487 (80.5%) participated in a follow-up survey in September 2020. We conducted multiple logistic regression analyses and text analyses to explore factors that encouraged and discouraged medical help-seeking. We also evaluated changes in menstrual symptoms and work productivity, using generalized estimating equations with interactions between the severity of PMS, help-seeking, and time. RESULTS: During the follow-up period, 4.9% of the participants (121/2487) sought medical help. Those having high annual income (adjusted odds ratio [aOR] = 2.07, 95% confidence interval [CI]: 1.21-3.53) and moderate-to-severe PMS (aOR = 2.27, 95% CI: 1.49-3.46) were more likely to have sought medical help. Those who did not seek medical help despite their moderate-to-severe PMS reported normalization of their symptoms (36%), time constraints (33%), and other reasons for not seeking medical help. Participants with moderate-to-severe PMS who had sought medical help showed a significant improvement of - 8.44 points (95% CI: - 14.73 to - 2.15 points) in intermenstrual MDQ scores during the follow-up period. However, there were no significant improvements in premenstrual and menstrual MDQ scores or absolute presenteeism. CONCLUSION: Medical help-seeking alleviated intermenstrual symptoms in women with moderate-to-severe PMS, but only a small proportion of them sought medical help after PMS education. Further research should be conducted to benefit the majority of women who are reluctant to seek medical help, including the provision of self-care information.

Japanese, Scientific journal - Fertility education: recommendations for developing and implementing tools to improve fertility literacy†.
Mariana V Martins, Emily Koert, Randi Sylvest, Eri Maeda, Mariana Moura-Ramos, Karin Hammarberg, Joyce Harper
Human reproduction (Oxford, England), 13 Dec. 2023, [Peer-reviewed], ［Internationally co-authored］, [International Magazine]
English, Scientific journal, Many recent societal trends have led to the need for fertility education, including the age at which individuals become parents, the development of new reproductive technologies, and family diversity. Fertility awareness has emerged as a concept very recently and is increasingly gaining recognition. However, fertility education is often neglected as there is no consensus on the appropriate content, target populations, or on who should provide it. This article attempts to provide an overview of the use of interventions to improve fertility education. We emphasize the importance of delivering evidence-based information on fertility and reproductive health through various methods while providing guidelines for their standardization and systematization. Recommendations are provided to aid the development and implementation of fertility education tools, including: the establishment of a comprehensive understanding of the target populations; the incorporation of theories of behavioural change; the inclusion of the users' perspectives and the use of participatory research; and the use of specific guidelines for increasing engagement. By following these recommendations, it is expected that fertility education resources can contribute to improving fertility literacy, empowering individuals and couples to make informed reproductive decisions, and ultimately reducing the incidence of infertility and need for fertility treatment. - The first nationwide website survey of the availability and costs of medical and non-medical oocyte cryopreservation in Japan

English, Scientific journal, RESEARCH QUESTION: How does the cost-related oocyte cryopreservation (OoC) vary by the facility in Japan, and what data is provided on the websites about OoC procedures? DESIGN: Website survey. The websites of all 621 facilities that provide assistive reproductive technology registered in Japan were surveyed in 2021. Data included the rates of explicit statements regarding the provision of OoC for only medical reasons (medical only group) or non-medical reasons (non-medical group). Based on whether or not facilities that perform OoC clearly stated the cost on their websites, we compared the costs of OoC and annual storage cost between medical only and non-medical groups. Furthermore, we examined the stated number of OoC procedures performed and their clinical outcomes. RESULTS: Of the 621 facilities, 146 (23.5%) clearly stated that they offer OoC on their websites. Of the 88 medical only groups and 58 non-medical groups, 24 (27.3%) and 42 (72.4%) clearly stated the OoC cost, and 27 (30.7%) and 44 (75.9%) clearly states the annual oocyte storage cost, respectively. The OoC costs were significantly higher for the non-medical group than in the medical group. In the medical only group, the annual storage cost remained almost the same regardless of the number of oocytes, while in the non-medical group, the annual storage cost was 2-3 times higher than in the medical only group. Only 16 facilities (16/146, 11.0%) had mentioned the number of OoC procedures, and five facilities (3.4%) provided information on the clinical outcomes after OoC. CONCLUSION: Costs related to OoC are higher for the non-medical group in Japan. In addition, the websites contain scant information on the costs and clinical outcomes of OoC. - Model-based estimation of the health care expenditure and out-of-pocket payment for assisted reproductive technology: A retrospective linkage study using the Japanese national ART registry.

English, Scientific journal, AIM: From April 2022, the Japanese government funding system for assisted reproductive technology (ART) has shifted from government subsidies to universal health insurance. To date, studies estimating the health care expenditure for ART are scarce. We estimated health care expenditures for ART cycles and compared the proportion of patients' out-of-pocket payment by ovarian stimulation protocols under the Japanese government subsidy system. METHODS: We linked payment information for government subsidies in Saitama Prefecture during 2016 and 2017 with the Japanese ART registry. Health care expenditures for all treatment cycles in Japan during 2017 among women aged <43 years (n = 369 757) were estimated using a generalized linear model. RESULTS: We linked 6269 subsidy applications to the Japanese ART registry. The average treatment fee for a fresh cycle was 376 434 JPY (standard deviation = 159 581). However, significant variation was observed across ovarian stimulation protocols. The estimated health care expenditure for ART during 2017 was 101 278 629 888 JPY (920 714 817 USD), leading to a 0.24% increase in the national health care expenditure for fiscal year 2017. Fresh cycles accounted for 70% of the expenditure. The proportion of the average patient out-of-pocket payment for one treatment cycle was smaller for natural (0%) and mild ovarian stimulation using clomiphene citrate (4.5%-20.7%) than those of conventional stimulation (30.3%-32.4%). CONCLUSIONS: Health insurance coverage for ART would increase national health care expenditure by 0.24%. Under the subsidy system, the proportion of the average patient out-of-pocket payment was smaller for natural and mild ovarian stimulation than conventional stimulations. - High TLR6 Expression Status Predicts a More Favorable Prognosis after Esophagectomy for Locally Advanced Thoracic Esophageal Squamous Cell Carcinoma.

English, Scientific journal, Most so-called "beneficial bacteria" in gut microbiota are Gram-positive, and TLR6 recognizes the peptidoglycan (PGN) present in their cell walls. We hypothesized that a high TLR6 expression status predicts a more favorable prognosis after esophagectomy. We used an ESCC tissue microarray (TMA) to examine TLR6 expression status in ESCC patients and to determine whether TLR6 expression status correlates with prognosis after curative esophagectomy. We also examined whether PGN influences the cell proliferation activity of ESCC lines. Clinical ESCC samples from 177 patients tested for the expression of TLR6 were categorized as 3+ (n = 17), 2+ (n = 48), 1+ (n = 68), or 0 (n = 44). High TLR6 expression (3+ and 2+) correlated with significantly more favorable 5-year overall survival (OS) and disease-specific survival (DSS) after esophagectomy than a lower TLR6 expression (1+ and 0). Univariate and multivariate analyses showed that TLR6 expression status is an independent prognostic factor that affects 5-year OS. PGN significantly inhibited the cell proliferation activity of ESCC lines. This is the first study to show that high TLR6 expression status predicts a more favorable prognosis in locally advanced thoracic ESCC patients after curative esophagectomy. PGN released from "beneficial bacteria" seems to have potential to inhibit the cell proliferation activity of ESCC. - Public funding of assisted reproductive technology in Europe and Asia

English, Scientific journal, BACKGROUND: Economic disparities affect access to assisted reproductive technology (ART) treatment in many countries. At the time of this survey, Japan provided partial reimbursement for ART treatment only for those in low- or middle-income classes due to limited governmental budgets. However, the optimal level of financial support by income class remains unclear. METHODS: We conducted a conjoint analysis of ART in Japan in January 2020. We recruited 824 women with fertility problems aged 25 to 44 years via an online social research panel. They completed a questionnaire of 16 hypothetical scenarios measuring six relevant ART attributes (i.e., out-of-pocket payment, pregnancy rate, risk of adverse effects, number of visits to outpatient clinics, consultation hours and kindness of staff) and their relations to treatment choice. RESULTS: Mixed-effect logistic regression models showed that all six attributes significantly influenced treatment preferences, with participants valuing out-of-pocket payment the most, followed by pregnancy rates and kindness of staff. Significant interactions occurred between high household income (≥ 8 million JPY) and high out-of-pocket payment (≥ 500,000 JPY). However, the average marginal probability of the highest-income patients (i.e., ≥ 10 million JPY, ineligible for the subsidy) receiving ART treatment at the average cost of 400,000 JPY was 47%, compared to 56 - 61% of other income participants, who opted to receive ART at an average cost of 100,000 JPY after a 300,000 JPY subsidy. CONCLUSION: Our results suggest that out-of-pocket payment is the primary determinant in patients' decision to opt for ART treatment. High-income patients were more likely to choose treatment, even at a high cost, but their income-based ineligibility for government financial support might discourage some from receiving treatment. - Relationship between somatic symptoms with menstruation and intention to leave work among university hospital nurses in Japan: a cross-sectional study.

English, Scientific journal, PURPOSE: This study investigated the association between menstrual symptoms and the intention to leave work among female nurses in Japan. METHODS: This cross-sectional study investigated female nurses (n = 317) at two university hospitals. The items measured were their characteristics (e.g., age, body mass index), "intention to leave" work, somatic symptoms related with menstruation, self-reported menstrual characteristics (e.g., pain), physical workloads (e.g., working hours and night shifts) and psychological workloads, measured with the Copenhagen Burnout Inventory (CBI), and the Job Content Questionnaire (JCQ). Participants with at least four somatic symptoms (e.g., cold, fatigue) which are present during their menstrual cycles were considered to have "somatic symptoms associated with menstruation." We also measured serum ovarian and gonadotropin-releasing hormones. RESULTS: Approximately 40% of women answered "intention to leave" work, and 17% had "somatic symptoms associated with menstruation." Multiple logistic regression analysis suggested that nurses reporting "somatic symptoms associated with menstruation" were more likely to have "intention to leave" work: the adjusted odds ratios (AOR, 95% confidence interval [CI]) were 2.15 (1.12-4.11) in the personal-burnout model, 2.23 (1.16-4.31) in the work-related burnout model, 2.91 (1.52-5.56) in the client-related burnout model; 2.96 (1.50-5.82) in the JCQ model. There was no association between serum and gonadotropin hormones and the intention to leave. CONCLUSION: Somatic symptoms with menstruation were associated with intention to leave work among female Japanese nurses. Intervention for somatic symptoms with menstruation might support nurses to continue work. - Working conditions contribute to fertility-related quality of life: a cross-sectional study in Japan

English, Scientific journal, Background: Assisted reproductive technology (ART) is a globally established treatment; however, large disparities exist in ART use among young couples. We investigated regional-level factors associated with ART use in Japan. Methods: We calculated the use rate of ART using the number of women aged <35 years who applied for government subsidies in 2017; we divided that figure by the number of women aged 20-35 years in each prefecture. Prefectural-level average household income; social capital indicators including voting rate, volunteer rate, and move-in rate; and Gini coefficients as indicators of income inequality were linked to ART use, adjusting for prefectural size, the mean age of women at first marriage, number of ART facilities, and additional prefectural subsidies. Results: The rate of ART use (per 10,000 women) varied significantly from 22.0 to 58.8 across Japan's 47 prefectures. Multivariate analysis demonstrated that the use rate increased by 0.048 (95% confidence interval [CI], 0.007 to 0.088) for each 10,000-yen increase in average household income and 1.5 (95% CI, 0.65 to 2.3) for each 1% increase in volunteer rate. Conversely, the use rate decreased by 18.4 (95% CI, -28.6 to -8.1) for each 1% increase in the move-in rate. There was no significant association between ART use and income inequality. Conclusion: Although we cannot infer causal relationships, the findings suggest that improving financial access and enhancing social capital may increase access to ART. Further research, particularly multilevel analysis using individual data, is required to confirm these findings. - Development of a health literacy scale for preconception care: a study of the reproductive age population in Japan

English, Scientific journal, Purpose: We investigated the cumulative live birth rate (CLBR) in women receiving governmental subsidies for assisted reproductive technology (ART) in Saitama Prefecture, Japan. Methods: Women who applied for subsidies from Saitama Prefectural Government for the first time in 2016 were enrolled and followed up until the end of 2017. Treatment information, including live birth, was obtained from the Japanese ART registry by linking it with unique identification numbers for treatment. Patients' factors associated with having a live birth were investigated. Results: Of 1,072 women (2,513 applications), 495 (46.2%) had a live birth with 8 (1.6%) twin pregnancies. The CLBR over six subsidized cycles was 53.7% for women aged <40 years, and 17.2% over three subsidized cycles for women 40-42 years; highest among women <35 years (58.4%), followed by those aged 35-39 years (49.3%). Multivariate analysis revealed patient age as the only independent factor for having a live birth. Conclusions: The CLBR of women receiving subsidies for ART was greatest in women aged <35 years. Effective policies for promoting ART among younger couples who seek infertility treatment are essential. - PET-Uptake Reduction into Lymph Nodes After Neoadjuvant Therapy is Highly Predictive of Prognosis for Patients Who have Thoracic Esophageal Squamous Cell Carcinoma Treated with Chemoradiotherapy Plus Esophagectomy.

English, Scientific journal, BACKGROUND: Patients with 18F-fluorodeoxyglucose-positron emission tomography (FDG-PET)-positive lymph nodes before treatment have a poor prognosis after esophagectomy. This study investigated whether FDG uptake into lymph nodes on FDG-PET (PET-N) during the pre- or posttreatment stage is more predictive of survival for thoracic esophageal squamous cell carcinoma (TESCC) patients who received neoadjuvant chemoradiotherapy (NACRT) followed by esophagectomy. METHODS: Of 129 TESCC patients with clinical lymphatic metastasis who underwent curative-intent esophagectomy after NACRT between 2010 and 2018, 97 who received PET before and after NACRT were enrolled in the study. The study defined lymph nodes with a maximum standardized uptake value (SUVmax) greater than 2.5 on FDG-PET before NACRT as cPET-N(+) and after NACRT as CRT-cPET-N(+). Both the cPET-N(+) and CRT-cPET-N(-) patients were defined as PET-N responders. Survival was analyzed using the Kaplan-Meier method and Cox proportional hazard models. RESULTS: No significant difference in survival was detected between the cPET-N(+) and cPET-N(-) patients. However, the CRT-cPET-N(-) patients had significantly better 5-year overall survival (OS) and disease-specific survival (DSS) than the CRT-cPET-N (+) patients. The PET-N responders had significantly better 5-year OS and DSS than the PET-N non-responders, and PET-N response was an independent prognostic factor for 5-year DSS. CONCLUSION: The PET-N response is a highly predictive prognostic marker for TESCC patients who undergo NACRT followed by esophagectomy. The PET-N response may help clinicians to establish a strategy for perioperative treatments that improves survival for patients with lymph node metastasis in TESCC. - Household income and medical help-seeking for fertility problems among a representative population in Japan.

English, Scientific journal, BACKGROUND: Fertility treatments help many infertile couples to have children. However, disparities exist in access to fertility tests and treatments. We investigated the association between household income and medical help-seeking for fertility in Japan. METHODS: We conducted a cross-sectional study using nationally representative data from the National Fertility Survey 2015. Respondents were 6598 married women younger than 50 years old. The primary outcome was medical help-seeking for fertility among those who experienced fertility problems. Multiple logistic regression models were used to assess the association between household income and medical help-seeking, adjusting for age, length of marriage, educational level, employment status, number of children, childbearing desires, living with parents, and region of residence. RESULTS: Among 2253 (34%) women who experienced fertility problems, 1154 (51%) sought medical help. The proportion of help-seekers increased linearly from 43% in the low-income group (< 4 million Japanese yen [JPY]) to 59% in the high-income group (≥ 8 million JPY) (P for trend < 0.001). Respondents with upper-middle (6-8 million JPY) or high household income were more likely to seek medical help, compared to those with low household income: adjusted odds ratio [aOR] 1.37 (95% confidence interval [CI]: 1.00-1.86) and aOR 1.78 (95% CI: 1.29-2.47), respectively. CONCLUSIONS: We found that higher household income was associated with a higher probability of seeking medical help among Japanese women who experienced fertility problem. Along with policy discussion about additional financial support, further studies from societal, cultural, or psychological views are required. - Differences in treatment and survival between elderly patients with thoracic esophageal cancer in metropolitan areas and other areas.

English, Scientific journal, To address the major issue of regional disparity in the treatment for elderly cancer patients in an aging society, we compared the treatment strategies used for elderly patients with thoracic esophageal cancer and their survival outcomes in metropolitan areas and other regions. Using the national database of hospital-based cancer registries in 2008-2011, patients aged 75 years or older who had been diagnosed with thoracic esophageal cancer were enrolled. We divided the patients into two groups: those treated in metropolitan areas (Tokyo, Kanagawa, Osaka, Aichi, Saitama, and Chiba prefectures) with populations of 6 million or more and those treated in other areas (the other 41 prefectures). Compared were patient backgrounds, treatment strategies, and survival curves at each cancer stage. In total, 1236 (24%) patients from metropolitan areas and 3830 (76%) patients from nonmetropolitan areas were enrolled. Patients in metropolitan areas were treated at more advanced stages. There was also a difference in treatment strategy. The 3-year survival rate among cStage I patients was better in metropolitan areas (71.6% vs. 63.7%), and this finding mainly reflected the survival difference between patients treated with radiotherapy alone. For cStage II-IV patients, there were no differences. Multivariable Cox proportional hazard analysis including interaction terms between treatment areas, cStage, and the first-line treatments revealed that treatments in the metropolitan areas were significantly associated with better survival among patients treated with radiotherapy alone for cStage I cancer. Treatment strategies for elderly patients with thoracic esophageal cancer and its survival outcomes differed between metropolitan areas and other regions. - コンジョイント分析による生殖補助医療の費用と受療意思の関連の検討

English, Scientific journal, AIM: Due to the lack of national perinatal registries, population-wide descriptive statistics on cesarean deliveries in Japan are unknown. We aim to describe cesarean deliveries for overall and multiple pregnancies using the Japan National Database of health insurance claims. METHODS: We calculated the national and prefectural cesarean delivery rates for overall and multiple pregnancies in 2014. We described maternal morbidities (e.g., blood transfusion) and the place and type of the institutions providing prenatal and perinatal care. RESULTS: The national cesarean delivery rates were 18.6% overall and 82.7% for women with multiple pregnancies. Prefectural cesarean delivery rates for overall and multiple pregnancies varied from 12.5% to 24.2% and from 49.2% to 100%, respectively, showing a moderate positive correlation (r = 0.59, p < 0.001). Overall, 1.4% of cesarean patients received an allogeneic blood transfusion, compared to 3.2% for those with multiple pregnancies. In addition, 65.9% of overall cesarean deliveries occurred at hospitals with ≥20 beds, whereas 94.6% of cesarean patients with multiple pregnancies delivered at hospitals. Older patients were more likely to receive their cesarean section at a different institution than their first visit within the same prefecture, but trans-prefectural movement during pregnancy covered by health insurance was most frequent among those in their early thirties: 7.0% overall and 10.7% for multiple pregnancies. CONCLUSIONS: The overall cesarean delivery rate in Japan was optimal, but the rate was high for multiple pregnancies, with large regional differences. Data on patient movement across institutions and areas would help to improve the perinatal care system. - Effects of localisation of uterine adenomyosis on outcome of in vitro fertilisation/intracytoplasmic sperm injection fresh and frozen-thawed embryo transfer cycles: a multicentre retrospective cohort study.

English, Scientific journal, BACKGROUND: Uterine adenomyosis is a benign disease, common among women in their 40 and 50 s, characterised by ectopic endometrial tissue in the uterine myometrial layer. Adenomyosis causes infertility and has a negative effect on the outcomes of in vitro fertilisation (IVF)/intracytoplasmic sperm injection (ICSI) embryo transfer (ET) cycles. It has also been reported to have different characteristics depending on the adenomyotic lesion localisation. The effect of its localisation on IVF/ICSI-ET outcomes is unclear. This study aimed to investigate whether adenomyotic lesion localisation, assessed using magnetic resonance imaging (MRI), was associated with outcomes of IVF/ICSI-ET cycles. METHODS: This multicentre, joint, retrospective cohort study analysed the medical records of 67 infertile patients with adenomyosis who underwent IVF/ICSI with fresh and frozen-thawed ET at five participating facilities from January 2012 to December 2016 and for whom MRI data were available. Fifteen patients were excluded; therefore, the MRI data of 52 patients were evaluated by two radiologists. We assessed the localisation of and classified adenomyotic lesions into advanced (invades the full thickness of the uterine myometrium), extrinsic (localised on the serosal side), and intrinsic (localised on the endometrial side) subtypes. RESULTS: There were 40 advanced, nine extrinsic, and three intrinsic cases, and the outcomes of 100, 27, and nine ET cycles, respectively, were analysed. Pregnancy loss/clinical pregnancy and live birth rates of the advanced, extrinsic, and intrinsic groups were 64 % (16/25) and 9 % (9/100), 33.3 % (3/9) and 22.2 % (6/27), and 50 % (1/2) and 11.1 % (1/9), respectively. A logistic regression analysis adjusted for age, prior miscarriage, and body mass index showed that the extrinsic group had fewer pregnancy losses (odds ratio 0.06; 95 % confidence interval [CI]: 0.00-0.54, p = 0.026) and more live births (odds ratio 6.05; 95 % CI: 1.41-29.65, p = 0.018) than the advanced group. CONCLUSIONS: Adenomyotic lesions exert different effects on IVF/ICSI-ET outcomes. Thus, MRI assessments of adenomyosis in infertile patients are beneficial. Establishment of treatment plans based on adenomyotic lesion localisation should be considered. - Cross-sectional survey of depressive symptoms and suicide-related ideation at a Japanese national university during the COVID-19 stay-home order.

English, Scientific journal, BACKGROUND: Insulin-like growth factor-II mRNA binding protein 3 (IGF2BP3) is an oncofetal RNA-binding protein normally involved in cell growth and migration during the early stages of embryogenesis. However, it is also expressed in various cancers, and the relationship between IGF2BP3 and the clinicopathological features and prognosis of esophageal squamous cell carcinoma patients is not fully understood. Our aim in this study was to determine whether IGF2BP3 expression status correlates with prognosis in patients with advanced thoracic esophageal squamous cell carcinoma. METHODS: The IGF2BP3 expression statuses of 177 patients treated with esophagectomy without preoperative therapy were evaluated immunohistochemically using tissue microarray analysis. The relationships between IGF2BP3 expression status and clinicopathological features and survival were then assessed using appropriate statistics. RESULTS: Among 177 esophageal tumors, 122 (68.9%) expressed high levels of IGF2BP3. In patients undergoing surgery alone, IGF2BP3-high expression was significantly associated with a poorer prognosis. By contrast, there were no significant associations between IGF2BP3 expression and clinicopathological features or outcomes in patients treated with surgery plus postoperative adjuvant chemotherapy. CONCLUSIONS: IGF2BP3 positivity in advanced thoracic esophageal squamous cell carcinoma is associated with adverse clinical outcomes in patients treated with surgery alone. - 【QOLを考える】不妊症とQOL

English, Scientific journal, Blood arsenic has various toxicities including carcinogenicity, but urinary concentrations are often substituted to determine the exposure level. Since there is little information on the relation of urinary arsenic species to blood arsenic, the aim was to investigate relationships between blood total arsenic (T-As) and the urinary species adjusted by creatinine and specific gravity (SG). Blood and spot urine samples were collected from 109 Japanese subjects aged 18-66 years without occupational exposure. Positive correlations of blood T-As (median, 3.49 μg/L) with urinary creatinine-adjusted and SG-adjusted T-As and arsenobetaine were statistically significant and greater than those with the unadjusted ones. The magnitude of associations of blood T-As with creatinine-adjusted arsenic species was significantly larger than those with unadjusted or SG-adjusted ones. Most of the correlation coefficients among urinary arsenic species concentrations were significant in three adjustment methods, but there was not a significant correlation between monomethylarsonic acid and arsenobetaine after urinary creatinine and SG corrections. Given multiple regression analysis, plasma T-As concentrations showed significant relations to creatinine-adjusted T-As, dimethylarsinic acid, and arsenobetaine concentrations, but erythrocyte T-As did hardly reflect the variation of urinary arsenic species. In conclusion, creatinine-adjusted arsenic concentrations are suggested to be the most appropriate predictor of blood T-As; by contrast, use of the urinary unadjusted arsenic concentration may result in a misleading interpretation of inorganic arsenic toxicity because the associations between inorganic and organic arsenic species based on the unadjusted concentration were mutually close. Plasma T-As appeared to be the best indicator of low-level exposure in blood samples. - Live visualisation of electrolytes during mouse embryonic development using electrolyte indicators.

English, Scientific journal, Studies have shown that some electrolytes, including Na+ and K+, play important roles in embryonic development. However, these studies evaluated these electrolytes by using inhibitors or knockout mice, with no mention on the changes in the intracellular electrolyte concentrations during embryogenesis. In this study, we used the electrolyte indicators CoroNa Green AM and ION Potassium Green-2 AM to directly visualise intracellular concentrations of Na+ and K+, respectively, at each embryonic developmental stage in mouse embryos. We directly observed intracellular electrolyte concentrations at the morula, blastocyst, and hatching stages. Our results revealed dynamic changes in intracellular electrolyte concentrations; we found that the intracellular Na+ concentration decreased, while K+ concentration increased during blastocoel formation. The degree of change in intensity in response to ouabain, an inhibitor of Na+/K+ ATPase, was considered to correspond to the degree of Na+/K+ ATPase activity at each developmental stage. Additionally, after the blastocyst stage, trophectoderm cells in direct contact with the blastocoel showed higher K+ concentrations than in direct contact with inner cell mass, indicating that Na+/K+ ATPase activity differs depending on the location in the trophectoderm. This is the first study to use CoroNa Green AM and ION Potassium Green-2 AM in mouse embryos and visualise electrolytes during embryonic development. The changes in electrolyte concentration observed in this study were consistent with the activity of Na+/K+ ATPase reported previously, and it was possible to image more detailed electrolyte behaviour in embryo cells. This method can be used to improve the understanding of cell physiology and is useful for future embryonic development studies. - Promoting fertility awareness and preconception health using a chatbot: a randomized controlled trial.

English, Scientific journal, RESEARCH QUESTION: What are the effects of using a fertility education chatbot, i.e. automatic conversation programme, on knowledge, intentions to improve preconception behaviour and anxiety? DESIGN: A three-armed, randomized controlled trial was conducted using an online social research panel. Participants included 927 women aged 20-34 years who were randomly allocated to one of three groups: a fertility education chatbot (intervention group), a document about fertility and preconception health (control group 1) or a document about an irrelevant topic (control group 2). Participants' scores on the Cardiff Fertility Knowledge Scale and the State-Trait Anxiety Inventory, their intentions to optimize preconception behaviours, e.g. taking folic acid, and the free-text feedback provided by chatbot users were assessed. RESULTS: A repeated-measures analysis of variance showed significant fertility knowledge gains after the intervention in the intervention group (+9.1 points) and control group 1 (+14.9 points) but no significant change in control group 2 (+1.1 points). Post-test increases in the intentions to optimize behaviours were significantly higher in the intervention group than in control group 2, and were similar to those in control group 1. Post-test state anxiety scores were significantly lower in the intervention group than in control group 1 and control group 2. User feedbacks about the chatbot suggested technical limitations, e.g. low comprehension of users' words, and pros and cons of using the chatbot, e.g. convenient versus coldness. CONCLUSIONS: Providing fertility education using a chatbot improved fertility knowledge and intentions to optimize preconception behaviour without increasing anxiety, but the improvement in knowledge was small. Further technical development and exploration of personal affinity for technology is required. - 【プレコンセプションケアってなに?】世界のプレコンセプションケアの動向

English, Scientific journal, BACKGROUND: It will be important for the Japan Esophageal Society (JES) to show an evident advantage of its institution certification system. To achieve this essential task, we used nationally acquired big data to re-analyze 5-year survival information. METHODS: In 2008-2009, there were 4897 thoracic esophageal cancer patients who underwent esophagectomy and were registered in the National Database of Hospital-based Cancer Registries. We divided these patients into two groups, those who underwent surgery at an Authorized Institute for Board Certified Esophageal Surgeons (AIBCES) or a Non-AIBCES. We then compared the patient backgrounds and 5-year survival rates between these two groups, with and without propensity score matching. RESULTS: There were 3080 (63%) patients who underwent esophagectomy at an AIBCES and 1817 (37%) who underwent surgery at a Non-AIBCES. Comparison of the Kaplan-Meier survival curves using log-rank tests indicated a significant difference between the AIBCES and Non-AIBCES groups at all cStages (cStages I-IV). Multivariable Cox proportional hazard analysis stratified by clinical stage and adjuvant treatment revealed that AIBCES vs. Non-AIBCES is a significant independent factor (adjusted HR 0.78) for survival. After propensity score matching ensuring the backgrounds of the two groups being equivalent, there were significant differences in the 5-year survival rates for patients with cStages I-III disease between the AIBCES and Non-AIBCES groups. CONCLUSIONS: There is a survival advantage to undergoing esophagectomy at an AIBCES. The institute certification system from the JES will contribute to the future establishment of a more appropriate surgery delivery system for thoracic esophageal cancer. - Domestic work stress and self-rated psychological health among women: a cross-sectional study in Japan

English, Scientific journal, BACKGROUND: Despite the huge burden of domestic work on women in Japan, its effects on their health have been poorly investigated. We aimed to assess the association between domestic work stress and self-rated psychological health among women. METHODS: We conducted a cross-sectional survey using an online social research panel in February 2018. Participants were 2,000 women with paid work (the "workers" group) and 1,000 women without paid work (the "homemakers" group), aged between 25 and 59 years old and living with a partner. Self-rated psychological health (Mental Health and Vitality scales of the Japanese SF-36), occupational and domestic work stress (the Brief Job Stress Questionnaire), the 10-item Work-Family Conflict Scale, and sociodemographic factors were assessed. RESULTS: The workers had lower domestic job control and higher support from a partner and their parents than the homemakers (p < 0.001), whereas domestic job demand and psychological health were similar between the groups. After adjustment for the covariates using multiple linear regression models, better psychological health was significantly associated with lower domestic job demand, higher domestic job control, and having a young child in both groups. In addition, work-family conflicts and occupational job stress among the workers and caregiving among the homemakers showed negative associations with psychological health. CONCLUSION: Self-rated psychological health in women was associated with domestic work stress regardless of employment status. To promote women's health, we need to take into account the effects of domestic work, work-family conflicts, and social support from families, as well as occupational factors. - 妊孕性・不妊に関する知識を高める授業プログラムの開発

English, Scientific journal, BACKGROUND: Methylmercury exposure is a common health risk resulting from daily fish intake. However, studies addressing the link between methylmercury and infertility are limited and also inconsistent. In addition, no previous epidemiological studies have accounted for the interaction between methylmercury and selenium. We aimed to investigate the association between environmental exposures to metals and female fertility. METHODS: This case-control study included 98 infertile women receiving fertility treatment (infertile group) and 43 female workers in their thirties (control group) who provided blood samples and returned a questionnaire on lifestyles and dietary characteristics. Blood levels of mercury, lead, cadmium, arsenic, manganese, zinc, and selenium were compared between the groups. Spearman correlation analyses between anti-Müllerian hormone and the metals were conducted. RESULTS: The mean selenium level in blood (± SD) and the selenium/mercury molar ratio were significantly lower in the infertile group (189 ± 25 μg/L and 94.6 ± 44.3, respectively) than in the control group (200 ± 25 μg/L and 118.4 ± 70.5). By contrast, blood mercury levels after adjusting for blood selenium and age were significantly higher in the infertile group than in the control group. Multiple logistic regression analyses with the adjustment for the other metals and potential confounders confirmed significant associations of infertility with elevated mercury and reduced selenium levels. No significant correlations were observed between anti-Müllerian hormone and metals. CONCLUSIONS: Methylmercury and selenium exposures appear to have adverse and protective effects on female fertility, respectively. This is the first report to suggest the antagonistic interaction between methylmercury and selenium in relation to human female fertility. - Appropriateness of the institute certification system for esophageal surgeries by the Japan Esophageal Society: evaluation of survival outcomes using data from the National Database of Hospital-Based Cancer Registries in Japan.

English, Scientific journal, BACKGROUND: Since 2013, The Japan Esophageal Society has been certifying "Authorized Institute for Board Certified Esophageal Surgeon (AIBCES)" to contribute to improving national medical care by enhancing the professional knowledge and skills of esophageal surgeons. However, the appropriateness on this certification system has not yet been verified. Our aim was to assess the appropriateness of the institute certification system for esophageal surgeries used by the medical society. METHODS: Using data from the National Database of Hospital-based Cancer Registries, we analyzed the 5-year overall survival rates among 2135 patients with thoracic esophageal cancer who underwent an esophagectomy at 53 AIBCES or 141 non-AIBCES. RESULTS: There were 1343 (63%) patients who underwent surgery at an AIBCES and 792 (37%) who underwent surgery at a non-AIBCES. Registered patients were followed up for a median of 53 (range 1-88) months. Over the followed-up period examined, 670 (50%) patients treated at an AIBCES died and 455 (57%) treated at a non-AIBCES died. Comparison of the Kaplan-Meier survival curves indicated that patients with cStage II or cStage III disease treated at an AIBCES had significantly better 5-year survival rates than those treated at a non-AIBCES (55.4% vs. 44.9% and 38.0% vs. 30.3%, respectively). Univariate and multivariate analyses stratified based on stages and adjuvant therapies revealed that institute certification (AIBCES vs. non-AIBCES) is a significant independent factor for 5-year survival. CONCLUSIONS: The institute certification system used by the Japan Esophageal Society may be appropriate, as indicated by improved 5-year survival outcomes. The institute certification system has the potential to contribute to a more appropriate medical delivery system in the future. - Two-year follow-up of a randomized controlled trial: knowledge and reproductive outcome after online fertility education.

According to the preceding studies, the checkpoints to be scrutinized when a result is not consistent with those of other researchers are as follows: (1) whether the study included all crucial confounders, (2) whether it included any exposure marker or confounder with a U-shaped dose-response curve, (3) whether the outcome measure was conducted by two or more examiners that might lead to measurement bias, (4) whether such examiners picked up information about exposure levels of the subjects before measuring the endpoints, and (5) whether subjects with different genetic factors were included in the analysis. In addition, (6) researchers conducting a children's study on developmental effects due to toxic substances must keep in mind that the impact of prenatal methylmercury exposure, independent of postnatal exposure, may continue for at least seven years. (7) When an environmental health research emphasizes to be population-based study, the levels of exposure to environmental chemical substances in developed countries with strict environmental regulations may be too low to examine a dose-response relationship for critical dose estimation. Such risk assessment should be carried out among the subjects with a wide range of exposure levels.

Japanese,More than sixty years has passed since the outbreak of Minamata disease, and high-level methylmercury contaminations now seem nonexistent in Japan. However, mercury has been continuously discharged from natural sources and industrial activities, and the health effects on children susceptible to methylmercury exposure at low levels, in addition to mercury contamination from mercury or gold mining areas in developing countries, become a worldwide concern. In this article, we provide a recent overview of epidemiological studies regarding methylmercury and mercury. The following findings were obtained. (1) Many papers on exposure assessment of methylmercury/mercury have been published since the Minamata Convention on Mercury was adopted in 2013. (2) The most crucial problem is child developmental neurotoxicity resulting from prenatal exposure to methylmercury, but its precise assessment seems to be difficult because most of such effects are neither severe nor specific. (3) Several problems raised in birth cohort studies (e.g., whether IQ deficits due to prenatal methylmercury exposure remain when the children become adults, or whether the postnatal exposure at low levels also causes such adverse effects in children) remain unsolved. (4) Concurrent exposure models of methylmercury, lead, polychlorinated biphenyls, aresenic, and organochlorine pesticides, as well as possible antagonists such as polyunsaturated fatty acids and selenium, should be considered in the study design because the exposure levels of methylmercury are extremely low in developed countries. (5) Further animal experiments and molecular biological studies, in addition to human studies, are required to clarify the mechanism of methylmercury toxicity.

Background : Based on results from the Japan Clinical Oncology Group (JCOG) 9204 and JCOG 9907 trials, neoadjuvant-CF (cisplatin+5-fluorouracil) followed by esophagectomy with extended lymphadenectomy is the standard treatment for patients with locally advanced thoracic esophageal squamous cell carcinoma (ESCC) in Japan. Recently, however, results from the JCOG 1109 trial revealed that neoadjuvant-DCF (docetaxel+cisplatin+5-fluorouracil) provides significantly better overall survival (OS) than neoadjuvant-CF, whereas neoadjuvant chemoradiotherapy (NACRT) did not produce significantly better outcomes than neoadjuvant-CF.Methods : We retrospectively identified 225 ESCC patients treated between December 2008 and December 2021 who received esophagectomy at Akita University Hospital. These patients were divided into neoadjuvant-CF (NAC, n=30) and NACRT (NACRT, n=195) groups before esophagectomy. Using the Kaplan-Meier method, we compared OS and disease-specific survival (DSS) between the two groups.Results : The pathological response to treatment was significantly better in the NACRT than the NAC group. Although 5-year OS and DSS were better in the NACRT than NAC group, these differences did not reach statistical significance.Conclusion : Among patients with locally advanced thoracic ESCC, NACRT produced a significantly better pathological response than NAC. However, NACRT did not produce significantly better long-term survival than NAC, which is consistent with the results of JCOG 1109., 秋田医学会, English - 【魚と健康-その健康影響と有益性を知る-】妊婦および乳幼児の魚摂取 健康リスク軽減のための食行動

This study evaluated the efficacy of combination therapy with steroids, PGE, and Stellate ganglion block for sudden idiopathic sensorineural hearing loss from April 2004 to December 2006 using the established clinical path. The patients comprised 51 ears, including 25 males (26 ears) and 25 females (25 ears), ranging from 15 to 81 years of age (average 51.8), and all were admitted to the hospital within 1 month from the onset of the disease. Hearing loss was assessed based on the criteria established by the Ministry of Health and Welfare Acute Severe Hearing Loss Group. The patients were distributed into four groups according to the severity of the disease. Recovery in the grade 1 group, was achieved within two weeks after the beginning of treatment. Grades 2, 3, and 4, showed a prolonged recovery, namely witni up to two months after the start of treatment. The improvement in the hearing level in the high frequency area was poor in all four groups. Those cases with diabetes mellitus (DM) showed a profound hearing loss, especially in the high frequency range and the improvement in this area was very poor., JIBI TO RINSHO KAI, Japanese - A case of parotid sialolithiasis successfully treated by extracorporeal shock wave lithotripsy

Endoscopic percutaneous dilational tracheostomy (PDT) has come to be used widely in intensive care units. PDT is simple to perform and is reported to be as safe as surgical tracheostomy, but changing of the tracheostomy tube after PDT may be difficult. Here, we report a case whose tracheostomy tube was misplaced in the anterior mediastinum during a tube change after PDT. This case demonstrates the potential danger of changing the tube in the post-operative period. The surgical method and PDT are shown to differ with regard to the dimensions of the tracheostomy orifice and the passage from the orifice to the trachea. Additionally, we propose solutions for tube misplacement after PDT., The Japan Broncho-esophagological Society, Japanese

先進諸国の男性の精液所見は近年悪化していることが知られていますが、一般男性を対象に生活環境要因と将来の妊娠出産との関係を長期的に評価した研究は極めて少ない状況です。本研究では男性を対象に、生活習慣や環境化学物質曝露等、修正可能なリスク因子を測定し、精液所見や将来の出生力との関連を明らかにします。さらに、将来の健康と家族形成を見据えた保健教育を実施し、男性への教育により不妊予防が可能か検討します。

Effects of toxic metals to standing postural sways and postural hand tremors were examined among workers of ferromanganese casting factories in a cross-sectional study. Spino-cerebellar disturbance type sway increase was found to be related to the increase in blood mercury (or arsenic). Decrease in several parameters including sway area when eyes closed were related to the increase in blood cadmium. Increase in blood manganese was related to the increase in 7 Hz tremor of dominant hand, and that in blood lead to the decrease in 10 Hz or larger frequency tremor of both hands.

Due to the lack of national perinatal registries, population-wide descriptive statistics on cesarean deliveries in Japan are unknown. We aim to describe cesarean deliveries for overall and multiple pregnancies using the Japan National Database of health insurance claims. We calculated the national and prefectural cesarean delivery rates for overall and multiple pregnancies in 2014. We described maternal morbidities (e.g., blood transfusion) and the place and type of the institutions providing prenatal and perinatal care. The national cesarean delivery rates were 18.6% overall and 82.7% for women with multiple pregnancies. Prefectural cesarean delivery rates for overall and multiple pregnancies varied from 12.5% to 24.2% and from 49.2% to 100%, respectively, showing a moderate positive correlation (r = 0.59, p < 0.001). The overall cesarean delivery rate in Japan was optimal, but the rate was high for multiple pregnancies, with large regional differences.

To investigate the association between environmental exposures to metals and female fertility, we conducted a case-control study, including 98 infertile women (infertile group) and 43 female workers in their thirties (control group) who provided blood samples and returned a questionnaire on lifestyles and dietary characteristics. Blood levels of mercury, lead, cadmium, arsenic, manganese, zinc, and selenium were compared between the groups. The mean selenium level in blood and the selenium/mercury molar ratio were significantly lower in the infertile group than in the control group. By contrast, blood mercury levels after adjusting for blood selenium and age were significantly higher in the infertile group than in the control group. Multiple logistic regression analyses confirmed significant associations of infertility with elevated mercury and reduced selenium levels. Methylmercury and selenium exposures appear to have adverse and protective effects on female fertility, respectively.

We examined nationwide CS statistics and evaluated the association with local resources for perinatal care. We used accumulated data for CS registered in the Japan National Database of health insurance claims in 2013 and calculated crude and age-standardized CS rates at national and prefectural levels. We analyzed the ecological associations with supply of obstetricians and institution and scale of obstetric facilities using multiple regression models. There were 190 361 cesarean deliveries in 2013, giving an overall CS rate of 18.5%, which varied by prefecture from 14.0% to 25.6%. In multiple regression analyses, the areal number of obstetricians (β = －0.58), the proportion of births at small-scale institutions (β = 0.36) and the number of beds at neonatal intensive care units per birth (β = －0.20) were significantly associated with the age-standardized elective CS rate . Higher elective CS rates might be associated with limited or unconsolidated medical resources.

【経済的支援が成長ホルモン分泌不全性低身長症の治療に与える影響】
財団法人成長科学協会の症例データベースを用いて、経済的支援の有無が小児慢性疾患医療費助成の終了基準到達後の治療に与える影響について検討した。2001年1月～2013年5月に助成終了基準身長に到達するまで小児慢性疾患医療費助成基準を満たした696名について、助成終了基準身長に到達後も治療を継続した者の割合は、何らかの公的経済的支援（市町村小児医療費助成等）のある患者で高かった。臨床的・その他の要因について多重ロジスティック回帰分析を用いて調整しても結果は同様であった。peer review誌に投稿中である。
【妊孕性知識の啓発を通じた、特定不妊治療費助成制度の効果的運用】
2014年4月、特定不妊治療費助成制度では早期治療のインセンティブとなるような年齢要件を伴った制度改正が行われたが、我が国の人々の妊孕性知識は、先進諸国に比べて低いとの報告がある。助成制度の効果的運用には、妊孕性知識を啓発し、計画的なライフプランや早期受診を促すことが重要である。(1) 35歳から44歳までの子供のいる男女690名について、初産年齢と10年以上前からの妊孕性知識について重回帰分析で検討したところ、10年以上前から知識があった女性では初産年齢は2.3歳若かった。妊孕性知識により、自身の家族形成についてインフォームドチョイスを実践できる可能性が示唆された。（Hum Fertil誌に採択済）(2）妊孕性に関する情報とその他の情報（葉酸摂取や社会保障に関する情報）で受け手の心理的負荷に差があるか明らかにする目的で、20歳から39歳までの将来子供が欲しい男女1455名を対象に、ランダム化比較試験を実施した。妊孕性に関する情報介入群では、男女とも妊孕性知識が有意に増加した一方、不安も有意に増加していた（peer review誌に投稿中）。
