  • Mental disorders, cancers, and cardiovascular diseases mediate the associations of psychosocial factors with well-being and ikigai

    Open AccessZui C Narita, K Inoue et al.ARTICLESSM - Mental Health2025

    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 …

  • Association between the number of social roles and self-rated health

    Yuka Suzuki, Kaori Honjo et al.ARTICLEJournal of Epidemiology and…2025References: 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 …

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…

  • Long-term exposure to fine particle matter and all-cause mortality and cause-specific mortality in Japan

    Open AccessNorie Sawada, Tomoki Nakaya et al.ARTICLEBMC Public Health2022

    We found evidence for a positive association between PM 2.5 exposure and mortality from cardiovascular disease in a Japanese population, even in an area with relatively low-level air pollution

  • Use of vitamin supplements and risk of total cancer and cardiovascular disease among the Japanese general population

    Open AccessAzusa Hara, Shizuka Sasazuki et al.ARTICLEBMC Public Health2011

    To our knowledge, this is the first prospective cohort study to examine simultaneously the associations between vitamin supplement use patterns and risk of cancer and CVD. This prospective cohort study demonstrated that vitamin supplement use has little effect on the risk of cancer or CVD in men. In women, however, consistent vitamin supplement use might reduce the risk of CVD. Elevated risk of cancer associated with past and recent use of vitami…

  • P1-348 Leisure-time physical activity and breast cancer risk defined by oestrogen and progesterone receptor status

    Reiko Suzuki, Motoki Iwasaki et al.ARTICLEJournal of Epidemiology and…2011

    Objective To investigate the association between leisure-time physical activity (LPA) and breast cancer risk in consideration of tumour oestrogen/progesterone-receptor (ER/PR) status. Methods We conducted a population-based prospective cohort study among 53 578 women in the Japan Public Health Center-based Prospective Study. LPA was assessed by self-reported questionnaires. A Cox proportional hazards regression model was used to derive RRs and 95…
