Non-linear dose-response association between physical activity and mental health in adolescents: a prospective cohort study based on SEARCH.

ABSTRACT:

Background

Adolescent mental health has emerged as a critical public health issue, with increasing prevalence of anxiety and depression. Physical activity (PA) is known to offer numerous health benefits, but its relationship with adolescent mental health is less clear and the optimal intensity and duration remain debated.

Methods

This prospective cohort study analyzed data from 6,991 adolescents in Jiangsu, China. Mental health was assessed using the Strengths and Difficulties Questionnaire (SDQ), and PA was categorized as moderate-intensity PA (MPA) or vigorous-intensity PA (VPA) based on self-reported activity levels. The study examined the cross-sectional and longitudinal associations between PA and mental health, adjusting for various confounding factors.
