Implication

Cross-sectional data reveals low physical activity and sleep duration increase odds of depressive symptoms in adolescents, suggesting health interventions are critical.

Key Points

To estimate prevalence of depressive symptoms and their associations with physical activity and sleep duration in Chinese adolescents.
Collected cross-sectional data through questionnaires in Ningbo, China.
Sample included adolescents aged 11-19 years via a multistage stratified cluster sampling procedure.
Depressive symptoms assessed using the Centre for Epidemiological Studies Depression Scale.
Utilized multivariate analysis to assess associations between lifestyle behaviours (physical activity, sleep duration) and depressive symptoms.
Prevalence of depressive symptoms among adolescents was 16.3%.
Low physical activity and short sleep duration were independently associated with greater likelihood of depressive symptoms (p < 0.001).
The unhealthiest patterns showed the highest odds of depressive symptoms (OR: 4.2, p < 0.001).
Other combined patterns of variable lifestyle factors significantly correlated with increased depressive symptoms.
