Note. BMI = body mass index; CI = confidence interval. Regressions were also adjusted for child's gender, age, race, ethnicity, mother's education level, and mother's BMI. Sampling weights were applied to produce population-level inferences. The sampling variance was estimated by the Huber–White method to reflect common variance among siblings.

^aBase model, n = 1118.

^bModel 1 plus physical activity mediators, n = 1118.

^cModel 1 plus eating while viewing mediator, n = 1114.

^**P < .05.
