Differential fatness gain of low income boys and girls

As shown in 564 girls and 553 boys followed for a period of 18 yr, long-term gain in both subscapular and triceps skinfold thickness was higher in children of lower family income level than those of higher family incomes. This differential fatness gain accounts for the socioeconomic "reversal" of fatness in the female shown in cross-sectional studies and newly extends the phenomenon to both sexes. The finding that low-income children show a greater long-term increase in fatness bears on the prevention and control of obesity.
