Time-varying Effects of Screen Media Exposure in the Relationship Between Socioeconomic Background and Childhood Obesity.

ABSTRACT:

Background

We investigated to what extent social inequalities in childhood obesity could be reduced by eliminating differences in screen media exposure.

Methods

We used longitudinal data from the UK-wide Millennium Cohort Study (n = 11,413). The study measured mother's educational level at child's age 5.

We estimated a counterfactual disparity measure of the unmediated association between mother's education and obesity by fitting an inverse probability-weighted marginal structural model, adjusting for mediator-outcome confounders.

Results

Compared with children of mothers with a university degree, chil
