Epidemiology of physical activity and fitness in children and adolescents

Sallis, James F.·1993·Critical Reviews in Food Science and Nutrition

Abstract

Variations in physical activity and aerobic power are examined in relation to age and gender of children and adolescents. Reviews of the world literature show aerobic power relative to body mass remains stable from ages 6 to 16 for males, but for females it declines about 2% per year. Overall, males are about 25% more fit than females. Reviews of nine studies using standardized self-reports or objective measures of physical activity revealed that males are about 15 to 25% more active than females. Over the school age years, a consistent decline in physical activity is seen, with males decreasing about 2.7% per year and females decreasing about 7.4% per year. These data suggest that older youth and females are at increased risk of obesity because of a sedentary lifestyle.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
