L. Myers et al., PHYSICAL AND SEDENTARY ACTIVITY IN SCHOOL-CHILDREN GRADES 5-8 - THE BOGALUSA HEART-STUDY, Medicine and science in sports and exercise, 28(7), 1996, pp. 852-859
Physical and sedentary activity in children and adolescents has immedi
ate health benefits and can also set a pattern that carries over into
adulthood, resulting in long-term health benefits. Activity levels in
a free-living biracial sample of children and adolescents, ages 9-15 y
r (N = 995), were examined using a 24-h recall instrument, the Self-Ad
ministered Physical Activity Checklist. Selected sedentary activities
(television watching and video-/computer-game playing) were also asses
sed. Overall, boys were more physically active than girls and engaged
in more heavy physical activity, while girls reported a larger percent
age of time spent in light and moderate physical activities. Gender an
d, to a lesser extent, ethnic differences were seen in the types of ac
tivities reported. Although most physical activity occurred after scho
ol, children who reported no physical education class during school ha
d less physical activity overall. There was a decrease in moderate phy
sical activity with increasing grade levels in school and an increase
in sedentary behavior. Black children reported more sedentary activity
than white children, and girls reported more than boys. Although this
24-h recall method has limitations, it allows characterization of the
activity of groups of children and provides useful data for policy re
commendations.
