Limiting TV Time: An Effective Strategy for Preventing Weight Gain in Children

Limit TV Time Prevents Children Weight GainReducing television viewing may be an effective strategy to prevent excess weight gain among adolescents, according to a new study released in the September/October 2012 issue of the Journal of Nutrition Education and Behavior.

Findings were based on a one-year community-based randomized trial that enrolled 153 adults and 72 adolescents from the same households. During that year, researchers from the University of Minnesota, School of Public Health Obesity Prevention Center conducted six face-to-face group meetings, sent monthly newsletters, and set-up 12 home-based activities. In addition, each household agreed to allow researchers to attach a "TV Allowance" to all televisions in the household for the one-year study period. Television viewing hours, diet, and physical activity levels were measured before and after the intervention.

A clear association was observed among adolescents between reduction in TV hours and decreased weight gain over one year. The TV hours’ impact on weight gain was not significant for adults. These findings suggest that television viewing is a risk for excess weight gain among adolescents. The implication is that parents who limit their adolescents’ television viewing may help their adolescent maintain a healthy body weight. According to national survey data [NHANES] 2003-2006, about 31% of US children and adolescents are overweight or obese, therefore finding the causes for weight gain in this population is growing increasingly important.
