Exercise had an insignificant effect on adolescents’ risk for depressive symptoms in a longitudinal, large population-based cohort study recently published in JAMA Pediatrics.
Umar Toseeb, PhD, of the University of Cambridge in Cambridge, United Kingdom, and colleagues assessed associations between physical activity and feelings of depression among 736 adolescents between November 2005 and January 2010. Individually calibrated heart rate and movement sensing determined physical activity at baseline, when study participants had a mean age of 14.5 years. Study participants completed the Mood and Feelings Questionnaire and a Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version interview at baseline and 3 years later.
