Childhood Physical Activity Declines Sooner than Previously Thought

Researchers examined 600 youths born from 2002 to 2004 and found that their total daily physical activity dropped by 75 minutes between ages 6 and 11, while their sedentary behavior rose by 107 minutes per day during the same period. The findings in Pediatrics also showed greater drops in light and moderate-to-vigorous physical activity among boys, as well as reduced total physical activity levels and elevated sedentary behavior levels among those with higher body mass index z-scores and fat mass index.
