Abstract

Background: The association between adolescent time spent on social media use and BMI z-score is unclear. Pathways of association and sex differences are also unclear. This study examined the association between time spent on social media use and BMI z-score (primary objective) and potential explanatory pathways (secondary objective) for boys and girls. Methods: Data are from 5,332 girls and 5,466 boys aged 14 in the UK Millennium Cohort Study. BMI z-score was regressed on self-reported time spent on social media use (hours/day). Potential explanatory pathways explored included dietary intake, sleep duration, depressive symptoms, cyberbullying, body weight satisfaction, self-esteem, and wellbeing. Sex-stratified multivariable linear regression and structural equation modelling were used to examine potential associations and explanatory pathways. Results: Using social media for ≥5 hours/day (vs.
