摘　　要：目的　研究不同体成分 10～ 12岁男女儿童皮褶厚度和唾液睾酮、雌二醇水平的变化趋势及其相互关系。方法　将 66名 10岁男孩和 75名 10岁女孩各分成肥胖、中等、消瘦 3组 ,追踪观察 3年 ,每年测定其皮褶厚度和唾液睾酮、雌二醇水平。结果　肥胖组男孩随年龄增加肱三头肌皮褶厚度下降 ,中等和消瘦组无明显的变化 ,3组间肩胛下角皮褶厚度变化不明显。肥胖组女孩随年龄增加肱三头肌皮褶厚度下降 ,中等组和消瘦组一直呈上升趋势 ,肩胛下角皮褶厚度仅肥胖组在 11岁时有一过性下降 ,其它 2组均呈上升趋势 ;男女儿童唾液睾酮和雌二醇水平随年龄增长而增加 ;男孩肩胛下角皮褶厚度与雌二醇水平呈负相关 ,女孩肱三头肌和肩胛下角部皮褶厚度与睾酮水平呈负相关。结论　 10～ 12岁不同性别儿童皮下脂肪发育趋势不同 ,不同体成分儿童皮下脂肪发育也存在差别 ;Objective To study the trend and relationship between ski nfold and salivary testosterone,estradiol levels of male and female children age d 10-12 with different body composition.Methods Sxity-six boys and 75 girls aged 10 were divided into obese,median and thin groups observed 3 years and determined their skinfold and salivary testosterone,estradiol levels every year.Results Obese boys and girls' triceps brachii skinfold de c reased with age,median and thin groups of boys had no significant trend,but the girls' increased with age.Boy's subscapular angle skinfold had no significant tr end with age,but the girls' increased except the obese group decreasing at 11.Th e testosterone and estradiol levels of boys and girls increased with age,and the boys' subscapular angle skinfold were correlated negatively with estradiol leve ls and the girls' triceps brachii and subscapular angle skinfold were correlated negatively with testosterone levels.Conclusion The skinfold development trend of children age d 10-12 were different in sex and body composition;the skinfold development in d ifferent site had relationship with sexual hormone levels.
