Longitudinal associations of screen time, physical activity, and sleep duration with body mass index in U.S. youth

CONCLUSIONS: One-year longitudinal associations between screen time and BMI may depend on form of screen time, what behavior it replaces (physical activity or sleep), and participant sex. The alternative statistical approaches yielded somewhat different results. Experimental manipulation of screen time and investigation of biopsychosocial mechanisms underlying the observed sex differences will allow for causal inference and can inform interventions.PMID:38566134 | DOI:10.1186/s12966-024-01587-6
