Impact of COVID-19 on the mental health of men experiencing homelessness: A cross-sectional study in Osaka, Japan

PLOS ONE, 18, 10, e0292377, e0292377, Public Library of Science (PLoS), Oct. 2023, [Peer-reviewed]
English, Scientific journal, The novel coronavirus infectious disease (COVID-19) pandemic has negatively impacted not only our physical health but also mental health, including increasing depressive and anxiety symptoms. In particular, socially and physically vulnerable populations, such as people experiencing homelessness (PEH), may be more likely to have their mental health worsened by the pandemic due to having more difficulty meeting basic human needs. Therefore, this study aims to assess the impact of COVID-19 on mental health of the homeless in Japan by evaluating depressive and anxiety symptoms and identifying the associated factors particularly, sociodemographic variables as age, employment status and the fear and perceived risk of COVID-19 infection. A cross-sectional interview survey among 158 PEH in Osaka Prefecture was conducted from April to May 2022. The survey included sociodemographic questions and history and perceived risk of infection with COVID-19. Depressive symptoms were measured using the nine-item Patient Health Questionnaire (PHQ-9) and anxiety symptoms using the seven-item Generalized Anxiety Disorder Scale (GAD-7), and the fear of COVID-19 using the seven-item Fear of New Coronavirus Scale (FCV-19S). In this study, the prevalence of depression (PHQ-9≥10) was 38.6%, anxiety disorder (GAD≥10) was 19.0%, and high fear of COVID-19 (FCV-19S≥19) was 28.5%. Univariate logistic regression analysis revealed that PEH in younger age groups (18–34 years), and with joblessness, higher perceived infection risk, and higher fear of COVID-19 were more likely to suffer from depression and anxiety (p<0.05). These results indicate that the younger PEHs with worsened economic conditions and therefore, feel threatened by COVID-19 the pandemic are at higher risk of mental health deterioration. More focused research and mental health services need to be provided to this population in the future.

Health and well-being in small island communities: a cross-sectional study in the Solomon Islands

English, Scientific journal, Objectives

This study explored the health problems of inhabitants of small South Pacific Islands under the influence of climate change, focusing on three communities in the Solomon Islands.

Design

Cross-sectional study of the Solomon Islands’ populations.

Setting

A field survey was conducted in Taro Island, a small, urbanised island with a whole-community relocation plan; Manuopo community of Reef Islands, a small remote island on an atoll environment and Sasamungga, an intermediately urbanised community on a larger island. The Sasamungga community was used for comparison.

Participants

Each community’s participants were recruited through local health authorities, and 113, 155 and 116 adults (aged 18+ years) from Taro, Manuopo and Sasamungga, respectively, participated voluntarily.

Methods

Each participant’s body height, weight and body mass index were measured. A drop of blood was sampled for malaria testing; glycated haemoglobin and C reactive protein levels, measured from another drop of blood, were markers for diabetes and inflammation, respectively. The Primary Care Screening Questionnaire for Depression measured depressive mental states.

Primary and secondary outcome measures

Regarding health status, the dependent variables—communicable diseases, non-communicable diseases and mental state—and independent variables—differences in communities and socioeconomic status—were measured through health check-ups and interviews of individual participants.

Results

Taro Island inhabitants had a higher risk of obesity (OR 1.13, 95% CI 1.02 to 1.27, p=0.0189), and Manuopo inhabitants had a higher risk of depression (1.25, 95% CI 1.08 to 1.44, p=0.0026) than Sasamungga inhabitants. Manuopo inhabitants recognised more serious problems of food security, livelihood, place to live and other aspects of daily living than other communities’ inhabitants.

Conclusions

The three small island communities’ observation identified different health problems: the urbanised community and remote community had a high risk of non-communicable diseases and mental disorders, respectively. These health problems should be monitored continuously during future climate-related changes.

現在、世界中で猛威を振るう新型コロナウィルスにより、大量の医療廃棄物や家庭ごみの発生など更なる廃棄物処理の負担が増していることが予測される。特に、低・中所得国の都市スラムなど脆弱なサニテーションインフラ問題を抱える地域では、防護装備不備での廃棄物回収および選別を担うごみ収集人が、感染症罹患などの健康リスクに晒されている。一方、感染を恐れる個人や社会による職業・人格・外観の蔑視を受けることによる自尊心浸食などメンタルヘルスの問題も深刻であると考えられる。


初年度は、コロナウィルス蔓延により渡航計画が難航したこともあり、１．調査地・対象者の選定ならびに関連組織の関係者への説明、２．調査項目について方法論の確認と検討、３．予備調査の内容に基づく成果発信、を中心に行った。以下、それぞれについて簡潔に説明する。
１＆２．カウンターパートである、インドネシアのNational Research and Innovation Agency（BRIN）と月例オンライン会議を通じて、調査研究内容の説明ならびに研究協力を要請し、内諾を得た。また、パンデミック渦における、現地事情を加味した渡航調査実施の可能性の検討を行った。具体的には、パンデミック渦において、医療廃棄物など無選別ごみを扱うエッセンシャルワーカーであるごみ収集人（サニテーションワーカー）が、社会からのネガティブなレスポンス（蔑視）に晒されることによる精神的健康（自尊心、QOLなど）への影響の解明に向けて、使用する質問紙ならびに分析方法の検討、半構造化インタビュー項目とその分析手法について、先行研究を整理し、カウンターパートと定期的に協議を重ねた。
３．感染症蔓延前に行った予備調査の内容に基づき、英文書籍執筆（分担執筆）ならびに国内外の学会、シンポジウム等（オンライン）で発表を行い、サニテーションワーカーが置かれた現状を発信した。
