Parental Guidance Advised: Associations Between Parental Television Limits and Health Behaviors Among Obese Children

OBJECTIVE: To examine associations between parental limits on TV viewing and child health behaviors. METHODS: We surveyed 816 parents of children 6 to 12 years of age who were participating in a primary care based obesity intervention. The main exposures were parental limits placed on child TV viewing time and TV content. Outcomes included screen-related behaviors, sleep habits, eating routines, and physical activity. We performed bivariate and multivariable analyses to examine independent associations of parental TV viewing rules with our outcomes. RESULTS: In multivariable analyses adjusted for child age, sex, race/ethnicity; parental education and US-born status; income and primary language, children whose parents set limits on TV time were less likely to have a TV in their bedroom (odds ratio [OR] 0.45; 95% confidence interval [CI] 0.31, 0.64) or to fall asleep while watching TV (OR 0.47; 95% CI 0.34, 0.67). Children with parental limits spent fewer weekday hours watching TV (-0.38 hours/day; 95% CI -0.54, -0.21), playing video or computer games (-0.15 hours/day; 95% CI -0.25, -0.04), and using the Internet (-0.08 hours/day; 95% CI -0.15, -0.006). In addition, children with limits on TV time were less likely to eat breakfast (OR 0.73; 95% CI 0.53, 0.99) or dinner (OR 0.53; 95% CI 0.39, 0.73) with the TV on, and they slept longer during weeknights: 0.21 hours/day (95% CI 0.05, 0.36). Moreover, children whose parents set rules on TV programming content were also less likely to have a TV in their bedroom (OR 0.37; 95% CI 0.18, 0.79). CONCLUSIONS: The relationship between parental limits on TV viewing and obesogenic child behaviors deserves further investigation.
