采用人体测量法对749名湖南侗族成人（男304人，女445人）皮褶厚度及体成分进行评价。侗族成人皮褶小腿内侧最薄，髂前上棘最厚；女性各项皮褶厚度值在大多数年龄段均显著高于男性；各年龄组中男性体密度、瘦体质量及其指数值高于女性，体脂率、脂肪质量及其指数值低于女性；随年龄增长，侗族男性皮褶厚度、体脂率、脂肪质量、瘦体质量值逐渐减小，体密度值逐渐增大；女性除小腿内侧皮褶总体呈下降趋势外，各项皮褶及体脂率、体质量指数、脂肪质量及其指数、瘦体质量及其指数值均先增后减，体密度值先减后增；与国内21个族群比较，侗族成人皮褶处于中等偏厚水平，与蒙古族相近，并具有南方族群特点；侗族男性脂肪发育水平和肥胖程度高于土家族，女性两民族脂肪发育水平相近。

In this project, anthropometric measurement was used to measure the height, body weight and four skinfold thickness of 749 Hunan Dong adults (304 males and 445 females), and body density, body fat percentage, fat mass, fat mass index, lean body mass and lean body mass index were calculated according to the formula. The results showed that both men and women of the Dong ethnic group had the thinnest thickness of the medial skinfold of the calf and the thickest thickness of the anterior superior iliac spinous skinfold. The thickness of the trunk skinfold in males is higher than that of the extremities; Except for the subscapular skinfold and anterior superior iliac spinous skinfold in the 20-year-old group, the thickness of each skinfold in women was significantly higher than that in men at all ages, and the difference was statistically significant. In each age group, the body density, lean body mass and lean body mass index values of males were higher than those of females, and the values of body fat percentage, fat mass and fat mass index were lower than those of females. With the increase of age, the thickness of the four skinfolds, body fat percentage, fat mass and lean body mass values of Dong males gradually decreased, and the body density value gradually increased. In women, triceps skinfold, subscapular skinfold, anterior superior iliac spinous skinfold, body fat percentage, body mass index, fat mass and fat mass index, lean body mass and lean body mass index increased first and then decreased, body density decreased first and then increased, and the thickness of the inner calf skinfold generally showed a decreasing trend. Compared with the other 21 ethnic groups in China, the triceps skinfold, subscapular skinfold and anterior superior iliac spinous skinfold of Dong men were relatively thick, while the medial calf skinfold was at a moderately thick level. The thickness of the anterior superior iliac spinous fold in Dong women was thicker, and the thickness of the other three skinfolds was at the moderate to thick level. The skinfold characteristics of males and females of the Dong ethnic group in Hunan were similar to those of the Mongolian Dulbert tribe, the Xinjiang Mongolian Chahar tribe, and the Xinjiang Mongolian Turgat tribe, and had the characteristics of the southern ethnic group. The fat development level and obesity level of Dong men were higher than those of Tujia men, and the fat development level of women was relatively close.
