Less TV Time for Better Bone Health
Watching too much TV raises the risk for obesity in children, and now a study suggests it could also lead to weaker bones. Among 1,181 people who researchers followed from birth to age 20, those who had consistently watched more than 14 hours per week of TV for most of their lives had much lower bone densities than did those who watched less. The link remained even after researchers adjusted for physical activity levels, calcium intake, and vitamin D levels, all of which can affect bone density. Studying the under-20 set is important because bone strength, and protection against fractures later on, is primarily gained during adolescence.
