Abstract
Objective: To investigate the associations of leisure-time physical activity with psychological 51 distress and wellbeing, and potential mediators. Methods: We used data from the 1970 British Cohort Study (N=5,197 - 2,688 men), including waves 34y (2004), 42y (2012), and 46y (2016) waves. Participants reported leisure-time physical activity frequency and intensity (exposure) at age 34 (baseline), cognition (vocabulary test), body mass index, disability, mobility and pain perception (potential mediators) at age 42, and psychological distress (Malaise inventory) and wellbeing (Warwick-Edinburgh scale) at age 46. Baseline confounders included sex, country, education, employment status, alcohol use, tobacco smoking, and psychological distress. Main analyses included logistic regression and mediation models. Results: Higher leisure-time physical activity intensity at baseline was associated with lower 6psychological distress at 46y [β: -0.038 (95%CI: -0.069 to -0.007)], but not leisure-time physical activity frequency. Baseline leisure-time physical activity frequency and intensity were 63 associated with higher psychological well-being at 46y [frequency: β: 0.089 (95%CI: 0.002 to 64 0.176); intensity: β: 0.262 (95%CI: 0.123 to 0.401); and total: β: 0.041 (95%CI: 0.013 to 0.069)]. 65 Only body mass index at 42y partially mediated the association between leisure-time physical 66 activity frequency (15.7%) and total leisure-time physical activity (6.2%) at 34y, with 67 psychological wellbeing at 46y. Conclusions: These findings highlight the role of leisure-time physical activity in psychological distress and wellbeing, with greater effect sizes associated with higher frequency and intensity of leisure-time physical activity. Future interventions should consider examining potential mediators of the association of leisure-time physical activity with psychological wellbeing, such as body mass index.
