Abstract IntroductionDifferent types of leisure-time sedentary behaviors (LTSBs) were suggested to play different roles in health. To date, little is known how these types of sedentary behavior are different between older adults with and without social vulnerability. We investigated the associations between social vulnerability, types of sedentary behavior, and health outcomes. MethodsThis cross-sectional study included 1,833 community-dwelling Japanese older adults. LTSBs were categorized into two types i.e. passive sedentary behavior (PSB; TV viewing, talking, and sitting around) and mentally-active sedentary behavior (MASB; computer-use and reading) by explanatory factor analysis. We conducted 1) logistic regression analysis to assess the associations between each type of LTSBs and health outcomes (overweight and psychological distress), and 2) analysis of covariance to estimate the adjusted means of PSB and MASB time according to socially vulnerable status (educational attainment, driving status, and physical limitation), adjusted for potential confounders. ResultsMean (±S.D.) of PSB and MASB time were 3.67 (±3.02) and 1.19 (±1.38) hours/day, respectively. Longer PSB time were significantly associated with overweight and psychological distress, whereas MASB time was not associated with these health outcomes. More PSB time was observed among men with lower educational attainment and women who do not drive a car and with physical limitation. Meanwhile, more MASB time was associated with higher educational attainment among both men and women.ConclusionPSB time, which showed clearer association with adverse health outcomes, were longer among older adults with social vulnerability, i.e. those with lower educational attainment, non-drivers and those with physical limitation.
