All values (2-y change in servings per day per hour per day of screen time at baseline) are βs; 95% CIs in parentheses. Values were estimated by using sex-stratified linear regression models (with the use of generalized estimating equations). Models were adjusted for age, age squared, baseline BMI, baseline height, Δheight, months between questionnaires, race-ethnicity [non-Hispanic white (yes or no)], physical activity (h/wk), Δphysical activity (h/wk), quintile of census tract median income, and frequency of family dinners. All models included the baseline and change in screen time (h/d) in the same model. Electronic games included video and computer games. Total screen time did not include computer or Internet use for homework, work, or other recreational use (except for computer and Internet games, which were encompassed by electronic games). *P < 0.05, **P < 0.01, ***P < 0.001.
