目的:研究屯堡人成人皮褶厚度值的年龄变化特点以及与中国其他族群之间的差异。方法:采用随机取样方法,在贵州省安顺地区调查了506例(男251例,女255例)乡村屯堡人的6项皮褶(面颊、肱二头肌、肱三头肌、肩胛下、髂前上棘、小腿内侧皮褶)厚度值,分析了屯堡人成人皮褶厚度值随年龄变化的特点。结果:屯堡人男性肩胛下皮褶最厚,肱二头肌皮褶最为菲薄,躯干部的皮下脂肪厚度高于四肢。女性则是肱三头肌皮褶最厚,肱二头肌皮褶最为菲薄。女性6项皮褶厚度值大于男性。男性6项皮褶厚度均与年龄不相关(P>0.05),女性只有面颊皮褶与年龄呈正相关(P<0.01)。对男女5个年龄组的6项皮褶厚度值进行方差分析,表明男性只有髂前上嵴皮褶的年龄组间差异具有统计学意义(P<0.01)。屯堡人6项皮褶厚度值大于中国南方族群。结论:屯堡人皮下脂肪发育与南亚类型族群差距较大,相对接近于其他汉族族群,特别是与汉族(四川)、汉族(江苏)、汉族(安徽)以及布里亚特人接近。
Objective: To study the age-specific characteristics of adult skinfolds in Tunpu and their differences with other ethnic groups in China. Methods: Sixty-five skin folds (cheeks, biceps, triceps, subscapular, triceps, triceps, Anterior superior iliac spine, medial fold of calf), and analyzed the characteristics of tunable adult skinfold thickness with age. Results: Tunpu people were the most scapular skinfold folds, biceps skin fold the most meager, trunk subcutaneous fat thickness is higher than the limbs. Female is the thickest triceps skin fold, biceps skin fold the most meager. Six women skinfold thickness greater than men. There was no correlation between age and age in 6 males (P> 0.05). There was only a positive correlation between cheek fold and age in females (P <0.01). An analysis of variance (ANOVA) of six skinfold thickness values in five age groups showed that there was a statistically significant difference in ages among the men with only anterior superior iliac crest fold (P <0.01). Tunpu people six skinfold thickness greater than the southern Chinese ethnic groups. CONCLUSION: The subcutaneous fat development of Tunpu has a large gap with the South Asian type ethnic group, which is relatively close to other Han ethnic groups, especially with Han (Sichuan), Han (Jiangsu), Han (Anhui) and Buryat.
