Dose-Response Associations between Physical Activity and Poor Mental Health among High-School Students: Sleep Duration as a Potential Mediator

: Backgrounds: This study examined whether sleep duration may potentially mediate the association between moderate-to-vigorous physical activity (MVPA) and mental health between in a nationally representative sample of U.S. high school students. Methods: Data from 15,671 U.S. high school students participating in the 2023 Youth Risk Behavior Survey (YRBS) were analyzed. MVPA was measured as weekly days achieving at least 60 min of activity, and frequent poor mental health was defined as reporting poor mental health most of the time or always during the past 30 days. Sleep duration was evaluated as a mediator. Survey-weighted regression and Karlson–Holm–Breen mediation analyses were performed, adjusting for relevant sociodemographic and health-related covariates. Results: Each additional day of MVPA was associated with a 7.5% lower odds of frequent self-reported poor mental health (OR = 0.925, 95% CI: 0.898–0.954), while each additional hour of sleep was associated with a 29.0% lower odds (OR = 0.710, 95% CI: 0.668–0.756). KHB mediation analysis indicated that sleep duration emerged as a potential mediator of this association. The total association between MVPA and frequent poor mental health was β = − 0.048 (95% CI: − 0.072 to − 0.025), with an indirect effect through sleep duration of β = − 0.025 (95% CI: − 0.031 to − 0.019), accounting for 52.0% of the observed association. The proportion of the association accounted for by sleep duration was higher in females (55.68%) than in males (44.22%). Conclusions: More frequent achievement of the 60-min PA guideline was associated with lower odds of frequent poor mental health among U.S. high school students. Sleep duration accounted for approximately one-half of this observed association, supporting its potential role in the relationship between physical activity and mental health. Strategies that promote both regular physical activity and adequate sleep may help improve adolescent mental health.

Prevalence of anxiety and depression symptoms under population-level alcohol reduction to low-risk drinking: A parametric g-computation analysis in a U.S. nationwide cohort

Associations of reallocating time between physical activity, sedentary behavior, and sleep with mental health among Chinese adolescents: an isotemporal substitution analysis

Reallocating time toward sleep and PA was associated with reduced depressive and anxiety symptoms, particularly among adolescents with insufficient sleep, and accounting for sleep status may help advance understanding of the associations between movement behavior reallocations and adolescent mental health.

Perceived Stress and Domain-Specific Physical Activity in Relation to Anxiety and Somatic Symptom Burden Among Romanian Adults: A Cross-Sectional Online Survey

Perceived stress showed the strongest association with both anxiety and somatic symptom burden, and the use of a single total activity score concealed a more specific inverse association between vigorous leisure-time activity and somatic symptoms.
