Research Impact: Multi-level random effects meta-analysis of 111 studies of >3mil adults from showed that odds of incident cases or an increase in subclinical depressive symptoms were reduced after physical activity exposure by 21% in fully adjusted analyses. Odds were lower after moderate and vigorous physical activity that met guidelines than after light activity, and when physical activity exposure increased over time compared with a single baseline exposure. Expanding the scope and elevating the methods of prior reviews, findings showed that customary and increasing levels of moderate-to-vigorous physical activity are inversely associated with incident depression and onset of subclinical depressive symptoms.
