Associations of leisure-time occupational and commuting physical activity with risk of depressive symptoms among Japanese workers: a cohort study

摘要

BackgroundLeisure-time physical activity is associated with a lower risk of depression. However, the precise shape of the dose–response relationship remains elusive, and evidence is scarce regarding other domains of activity. We prospectively investigated associations of physical activity during leisure, work, and commuting with risk of depressive symptoms in Japanese workers.
