A Systematic Review of Screen Time and Obesity in Children, Adolescents, and Young Adults: Sex-Specific Pathways and Implications for Public Health Interventions

Introduction

Screen time is associated with multiple adverse health outcomes, including obesity. However, evidence for children and adolescents is limited and inconsistent, and potential sex-specific differences have not been characterized. This systematic review aimed to synthesize evidence on the association between screen time and obesity-related outcomes among children, adolescents, and young adults, with a focus on sex-specific pathways and implications for public health interventions.
