If you're in the process of redecorating your child's room, you may want to consider taking out the television set. New research suggests that having a TV in your child's bedroom can lead to some serious weight gain. Researchers from Dartmouth University collected and analyzed data from more than 3,000 children between the ages of 10 and 14, 60 percent of whom have TVs in their bedrooms. Those who have TVs in their room gained an extra pound per year compared to those who do not, even after taking into account outside factors, such as socioeconomic status, parenting styles, education levels, and total TV viewing time. The researchers note that having a TV in your child's bedroom does not directly cause weight gain, but it is linked to behaviors that can do so, such as being sedentary, exposure to high-calorie food ads, and more snacking.
