摘　　要：目的：通过皮褶厚度了解拉萨市藏族青少年体脂含量的现状。方法：选择拉萨市10b19岁藏族青少年共1110人，测量身高、肱二头肌皮褶厚度、肱三头肌皮褶厚度、肩胛下角皮褶厚度和髂棘上皮褶厚度，应用Mabel等提出的皮褶厚度公式进行体脂含量的推算。结果：拉萨市藏族青少年体脂含量在正常范围者仅占44．4％，营养不足者占28．5％，超重者占14．5%，肥胖者占12．6％。男生身体脂肪百分比（％BF）与年龄呈低度正相关（r-0．491），与皮褶厚度总和呈高度正相关（r-0．920）；女生％BF与年龄呈正相关（r-0．692），与皮褶厚度总和呈低度正相关（r-0．384）。结论：女生在各年龄段的皮褶厚度及其总和均值均高于男生，拉萨市藏族青少年中女生营养不良发生率高于男生，男生肥胖发生率高于女生，研究结果为提高西藏自治区青少年的身体素质提供参考数据。Objective： To study the body fat percentage of Tibetan nationality adolescents in Lhasa by measuring their skin- fold thickness. Methods： 1 110 Tibetan nationality adolescents aged 10-19 years in Lhasa were selected to measure the height, biceps skinfold thickness, triceps skinfold thickness, subscapular skinfold thickness and suprailiac skinfold thickness to calculate their body fat percentage by Mabel Deurenberg-Yap＇s equation. Results： With the normal range of body fat per- centage in Lhasa Tibetan nationality adolescents constituted only 44. 4%, However, malnutrition 28. 5%, overweight 14. 5%, and obesity 12. 6%. For the boys, there was a low correlation between percentage body fat（%BF） and age （r= 0. 491, P〈0. 001）, and a high positive correlation between BF% and the sum of skinfold thickness （r=0. 920, P〈0. 001） ; for the girls, there was a significant positive correlation between %BF and age （r=0. 692, P〈20. 001）, and a low correlation between %BF and the sum of skinfold thickness （r=0. 384, P〈0. 001）. The skinfold thickness and its sum/mean of the girls in different age groups were higher than those of the boys. Conclusion： Among the Tibetan nationality adolescents in Lhasa, the girl＇s malnutrition rate is higher than the boy＇s, and the boy＇s obesity rate is higher than the girl＇s. The results of present study provide reference data for improving the adolescent fitness in Tibet Autonomous Region.
