Physical activity and positive mental wellbeing in a cohort of baby boomers: results from a British prospective cohort

Background Maintaining wellbeing in later life is a key component of healthy ageing. Identifying modifiable factors associated with positive mental wellbeing in later life is thus an important priority, especially in the context of global population ageing. We aimed to investigate associations of monitored free-living and self-reported leisure time physical activity (LTPA) with positive mental wellbeing in early old age.
