Madonna had it right - a study proves that too much television can have a long-lasting impact on your child's health and intellect.

A study of over 1,300 Canadian children reveals that toddlers who watch a substantial amount of television turn into ten-year-olds who are heavier, worse at math and bullied more often than their non-TV-watching peers.

Researchers had parents track their children's television habits at two different ages, then had their teachers track the children's health, social activity and academic performance when the kids reached age 10. At 29 and 53 months, the kids averaged 8.8 and 14.8 hours of television per week, respectively.

When the kids reached ten years old, researchers found with each extra hour of television the toddlers watched, by age 10, their math skills decreased by 6%, their BMI increased by 5% and they were 10% more likely to be victimized by bullies.

It's tough to argue with numbers like this. It's probably best to limit your kids' TV habits to just a bit of Sesame Street each week. (Newser)
