  • Mental disorders, cancers, and cardiovascular diseases mediate the associations of psychosocial factors with well-being and ikigai: A population-based cohort study

    Open Access•Zui C Narita, K Inoue et al.•ARTICLE•SSM - Mental Health•2025

    While the role of psychosocial factors in well-being appears plausible, evidence is still limited in Asian populations, and the underlying mechanisms remain unclear. We applied the g-formula to JPHC-NEXT data to examine the longitudinal association of social support, social trust, and social network (assessed via marital status, contact with relatives, contacts with friends, and group associations) at baseline with well-being and ikigai (purpose …

  • Pufa, fish intake and risk of disabling dementia in Japan: The Japan Public Health Centre Disabling Dementia Study

    Open Access•Sarah Krull Abe, Manami Inoue et al.•ARTICLE•Public Health Nutrition•2025

    Objective: The aim of this study was to assess the association between fish intake, n -3 PUFA, n -6 PUFA and risk of disabling dementia. Design: Prospective cohort. Setting: Municipalities within the Japan Public Health Centre-based Prospective Study. Participants: 43 651 participants: (20 002 men and 23 649 women). Results: Exposure intake of fish, n -3 and n -6 PUFA was evaluated in 1995–1997. We defined disabling dementia cases as participants…

  • Association between the number of social roles and self-rated health: Mediation effect by ikigai and the size of close social networks

    Yuka Suzuki, Kaori Honjo et al.•ARTICLE•Journal of Epidemiology and…•2025•References: 23

    Background Health effects of multiple role occupancy and their mechanism are not fully addressed. We examined (1) the association between the number of social roles and self-rated health (SRH) and (2) the mediation effects of ikigai (the sense of life worth living) and the size of close social networks to the association. Methods We analysed the cross-sectional baseline questionnaire data of the Japan Public Health Center-based Prospective Study …

  • Dietary behaviours and related lifestyles according to the presence or absence of skipping breakfast in Japanese adults: The JPHC-Next study

    Open Access•Chika Okada, Hiroyasu Iso et al.•ARTICLE•Public Health Nutrition•2023

    Objective: To assess dietary behaviours and related lifestyles according to the presence or absence of skipping breakfast. Design: We analysed the cross-sectional data from a baseline survey of a large-scale population-based cohort study in Japan conducted in 2011–2016. Participants provided information on dietary behaviours and lifestyles through a self-administered questionnaire. Skipping breakfast was defined as not eating breakfast at least o…

  • Perceived Level of Life Enjoyment and Risk of Developing Disabling Dementia: The Japan Public Health Center–Based Study

    Open Access•Tomokazu Tajima, Ai Ikeda et al.•ARTICLE•The Journals of Gerontology…•2023•References: 1

    A higher level of life enjoyment was associated with a lower risk of disabling dementia, particularly in the low-medium mental stress group. This finding suggests the importance of having life enjoyment by managing mental stress for reducing risk of disabling dementia

  • B‐type natriuretic peptide is predictive of hospitalization in community‐dwelling elderly without heart diseases

    Open Access•Yuji Shimizu, Masanori Nishinaga et al.•ARTICLE•Geriatrics and gerontology…•2009

    AIM: To examine prospectively the relationship between plasma B-type natriuretic peptide (BNP) levels in community-dwelling elderly and their hospitalization. METHODS: A total number of 644 subjects aged 65 years or older were recruited from the annual community health examinations. Those with a history of stroke or neurological findings were not included. After excluding those with old myocardial infarction, left ventricular dysfunction, moderat…
