摘要
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 childrens 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.
