对7~12岁的131名男孩和106名女孩的出生体重与学龄期相对皮下脂肪分布的关系进行了研究。用总样本的肩峰下皮褶与三头肌皮褶的比值(S/T)和总样本的两个躯干(肩峰下、腋下)与两个肢体(三头肌、小腿内侧)之和(T/E)来估计学龄期的相对脂肪分布。S/T比值(mm/mm)，男生0.62±-0.15，女生0.63+/-0.18；T/E比值(mm/mm)，男生0.58+/-0.13，女生0.59+/-0.16；体重指数(kg/m2)，男生17.1+/-2.4，女生16.9+/-2.2。控制年龄与体重指数或皮褶厚度总和、出生体重与皮褶比的二阶偏相关系数分别为：S/T为-0.22和-0.20(p<；0.01)，女孩为-0.29和-0.32(p<；0.01)；S/T和T/E为-0.18和-0.17(p<；0.05)，男孩为-0.06和-0.6。尽管相关性很低，但这种相关性表明，随着出生体重按比例下降，躯干上积累的皮下脂肪比四肢上积累的皮下脂肪更多，女性比男性更多。逐步多元回归分析结果表明，出生体重对学龄儿童相对皮下脂肪分布的变异有2%~8%的解释。
The relationship between birth weight and relative subcutaneous fat distribution at school age was considered in 131 boys and 106 girls 7 to 12 years of age. Relative fat distribution at school age was estimated with the ratio of the subscapular to triceps skinfolds (S/T) for the total sample, and with the ratio of the sum of two trunk (subscapular, midaxillary) to the sum of two extremity (triceps, medial calf) skinfolds (T/E) for subsamples of 102 boys and 63 girls. There were no sex differences in the S/T ratio (mm/mm), boys 0.62 +/- 0.15, girls 0.63 +/- 0.18; T/E ratio (mm/mm), boys 0.58 +/- 0.13, girls 0.59 +/- 0.16; and BMI (kg/m2), boys 17.1 +/- 2.4, girls 16.9 +/- 2.2. Second order partial correlations, controlling for age and the BMI or age and sum of skinfolds, between birth weight and the skinfold ratios are, respectively, -0.22 and -0.20 (p < 0.01) for S/T and -0.29 and -0.32 (p < 0.01) for T/E in girls, and -0.18 and -0.17 (p < 0.05) for S/T and -0.06 and -0.6 for T/E in boys. Though low, the correlations suggest that as birth weight decreases proportionally more subcutaneous fat is accumulated on the trunk than on the extremities, more so in females than in males. Results of stepwise multiple regression analyses indicate that birth weight accounts for from 2% to 8% of the variance in relative subcutaneous fat distribution at school age.
