Objectively measured physical activity and symptoms of psychopathology in general population adolescents from the SIGMA cohort

Less physical activity (PA) has been associated with the development of psychopathology in adolescence. Few studies, however, have focused on understanding nature PA – relationship and existing research relies mostly self-report measures, which are less reliable. In this study, we investigated relationships between objectively measured light (LPA) moderate-vigorous (MVPA), symptoms adolescents. 934 adolescents (63% female) aged 11–19 years from SIGMA cohort wore Fitbit Charge 2 measuring LPA MVPA during at least three days. Participants completed Brief Symptom Inventory-53, assessing general psychopathology, depression, anxiety, psychoticism. Model selection was conducted a subset dataset (n = 464) to determine best fit. The optimal model then fitted remainder 470). results selected linear indicated non-significant LPA, MVPA, This study does not provide evidence that higher durations alone relate reduced psychoticism adolescent population. A more integrative approach considering interdependency multiple lifestyle factors, as well domain, context, individual experience may add value PA-psychopathology relationship.
