Abstract
OBJECTIVES: To assess the association between hours of TV viewing and the trajectory of BMI growth from Kindergarten to Grade 5 among a national longitudinal cohort of 7,334 US children. METHODS: Multilevel growth curve modeling was used to estimate children's BMI growth trajectories as a function of hours of TV viewing over time while controlling for gender, race/ethnicity, SES, birth weight, and baseline age. RESULTS: Hours of TV viewing were significantly positively associated with the acceleration of BMI growth from Kindergarten to Grade 5. CONCLUSIONS: Hours spent watching TV may be contributing to the recent dramatic increase in the prevalence of overweight and obesity among children.
