Dose response association of objective physical activity with mental health in a representative national sample of adults: A cross-sectional study.

ABSTRACT: Although higher physical activity (PA) levels are associated with better mental health, previous findings about the shape of the dose-response relationship between PA and mental health are inconsistent. Furthermore, this association may differ according to sedentary levels. We investigated the cross-sectional dose-response associations between objectively measured PA and mental health in a representative national sample of adults. We also examined whether sedentary time modified the PA-mental health associations. Based on 2007-2013 Canadian Health Measures Survey data, PA and sedentary time were measured using accelerometry among 8150 participants, aged 20 to 79 years. Generalized additive models with a smooth function were fitted to examine associations between minutes per day of moderate
