Longitudinal and repeated cross-sectional analyses were conducted using the eight-wave panel data between 1987 and 2012 for the nationwide representative sample of Japanese elderly and the baseline survey in 2012 for the new elderly panel including those who were born after World War II.
The analyses revealed that non-family networks, cigarette smoking, BMI, exercise habit, and mobility function decreased with age, though not always linearly, and that their mean values and rate of change varied across birth cohorts for some variables. Cohort and/or survey year differences appeared differently for males and females, namely increase of social isolation was observed only among men. Among women, co-residence with adult children was losing beneficial effect on life satisfaction (LS), while positive association between contact with friends and LS increased, suggesting that predictors of subjective well-being could also vary across cohorts and/or survey year.
