We also found that for adolescents who spent 3 or more hours a day
doing sedentary activities, such as sitting while watching television, playing
computer games, talking with friends, or doing other sitting activities, had a
lower risk for being overweight compared to those who spent less than 3 h
doing these activities on a typical day. This finding was particularly true in
Egypt (OR: 0.645; 95% CI: 0.475-0.876), India (OR: 0.515; 95% CI:
0.301-0.883), and Guatemala (OR: 0.819; 95% CI: 0.719-0.933).
