Although we know skinfolds are related to body fatness in children, we are yet unable to determine
absolute amounts of body fat with certainty. As children mature, the relation of skinfold fat to body
fatness changes. Today, national percentile norms are the best frame of reference for interpreting
skinfold fat results.
The criterion for the wanted degree of fatness in children falls above the 50
th
percentile. Children
between the 50
th
and 25
th
percentile should maintain their weight at that level for the current year.
Those below the 25
th
percentile should be strongly encouraged to reduce their weight until their
skinfold fat measurement reaches a more acceptable level.
