June 27, 2011 -- Interventions aimed at reducing the amount of time children spend watching TV do work and may ultimately reduce their risk of weight gain and obesity, according to a new study.
The new analysis of 29 studies looked at several interventions designed to reduce screen time, including education on the problems linked to too much TV, counseling, use of media diaries to log TV time, reward systems, and efforts to increase physical activity. Overall, there was a small but significant reduction of screen time seen with these interventions, the study indicates. The study appears in the July 2011 issue of Pediatrics.
“There is a change in the amount of time of TV being viewed, but what we don’t know is if this change results in a change in weight or health status,” says study author Dayna M. Maniccia, DrPH, a clinical assistant professor in the department of health policy management and behavior at the University of Albany in New York.
“We know that there is an association between TV and higher weight and poor nutrition habits, and any decrease in TV viewing will have a snowball effect,” she says. “Media is so pervasive, so even a small change is a step in the right direction.” Today, media use or screen time includes TV as well as computers, cell phones, iPods, MP3 players, video game players, and other mobile devices.
