Nearly 200 third- and fourth-grade students were randomly assigned to two groups: a treatment group who received a long-term (18 lessons over the course of 6-months) curriculum on reducing television watching and video game playing, and a control group who did not. After the period, children in both groups were examined vis-à-vis their health. Children in the treatment group reported significantly less hours spent in front of the television, and had significantly lower BMIs, smaller waist circumferences, and so on.
Reducing television viewing may be a very cost-effective manner to fight childhood obesity. While there were no statistically differences between the two groups regarding high-fat food intake, and moderate to vigorous physical activity, students who spent less time in front of the TV were less likely to be obese.
