We all know that watching TV takes kids away from more active hobbies (such as kickball, baseball, and just plain running around playing made-up games). A new study in the American Public Health Association Journal indicates that while TV does leach away your child’s day it seems the countless advertising is even worse than TV itself.
Conclusions. The evidence does not support the contention that television viewing contributes to obesity because it is a sedentary activity. Television advertising, rather than viewing per se, is associated with obesity.
The way I read this is if your kids are going to watch TV opt for commercial-free television (Public Television, TiVo or similar system- where you can skip commercials or DVD’s).
