Teenage boys’ TV viewing a risk to bone health

Teenage boys who spend lots of time in front of the TV or computer screen are at risk of poorer bone health, research has found.

A study carried out in Norway found the same did not apply to girls, which it suggested could be explained by their different body fat distribution.

Researchers looked at how much time 15- to 18-year-olds said they spent sitting in front of screens at the weekend, with between four and six hours being the most common amount of time in the 1,000 students questioned.
