Abstract
Results
Between 1997 and 2004, the amount of time children (6- to 11-year-olds) spent engaging in sedentary behavior increased from
1.71 to 3.14 h/day (p < 0.05), while the amount of time adolescents (12- to 18-year-olds) spent engaging in sedentary behavior increased from 1.71
to 3.50 h/day (p < 0.05). Studying before and after school and watching TV/videos each accounted for about half the increase in sedentary
behavior. Both watching TV/videos and studying before and after school were significantly and positively associated with BMI
in males, but not in females.
