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.
在对564名女孩和553名男孩进行了为期18年的跟踪研究中发现，家庭收入水平较低的儿童，其肩胛下和肱三头肌皮褶厚度的长期增长高于家庭收入较高的儿童。这种不同的脂肪增加解释了横断面研究中所显示的女性肥胖的社会经济“逆转”现象，并且新的研究将这一现象扩展到了男女两性。低收入儿童肥胖的长期增长幅度更大这一发现，对肥胖症的预防和控制具有重要意义。
