浙江地区汉族成人皮褶厚度的年龄变化

摘要

目的:为分析浙江地区成人的皮褶厚度值及其年龄变化特点.方法:采用随机取样的方法,对浙江省诸暨市687例(城市男性144例,城市女性153例；乡村男性186例,乡村女性204例)成人面颊、二头肌、三头肌、肩胛下、髂前上棘、腓肠肌等6项皮褶厚度值及体脂发育情况进行了调查研究,分析了浙江地区成人的皮褶厚度值及其年龄变化特点.结果:女性各项皮褶厚度值及体脂百分含量(％)均比同年龄组的男性高,性别间差异均具有统计学意义.城市男性6项皮褶厚度值均高于乡村男性,城市女性除面颊皮褶外,其余5项皮褶厚度值均高于乡村女性,同性别间各项皮褶厚度值在城乡间差异均具有统计学意义,但男性差异比女性差异更明显.浙江地区城市男性、城市女性、乡村男性、乡村女性的面颊、髂前上棘皮褶厚度均与年龄呈正相关,腓肠肌皮褶厚度值与年龄呈负相关,此外,乡村男性的肩胛下皮褶厚度还与年龄呈正相关,而城市女性的三头肌皮褶厚度值与年龄呈负相关.结论:与我国其他族群成人相比,浙江地区汉族成人的皮褶厚度值与山西、山东地区汉族的最为接近,均具有北亚族群的类型特点.%Objective: To analyse the skinfold thicknesses characters of Han adults in Zhejiang with the increasing age. Methods : Using the random sampling method to research six skinfold thicknesses of adults (facial, triceps, biceps, subscapular, su-prailiac and calf) and the growth of body fat in 687 Han adults (144 urban males and 153 urban females, 186 rural males and , 204 rural females) in Zhuji city of Zhejiang province. To analyse the skinfold thicknesses characters of Han adults in Zhejiang with the increasing age. Results: (1) As a whole, the skinfold thickness of females was thicker than that of males and the body fat percentage (%) was higher than that of males at the same age group, and there were statistically significant differences between genders. (2) As a whole, the skinfold thickness of urban males was thicker than that of rural males, and the remaining 5 skinfold thickness of urban females except facial were thicker than those of rural females. There were statistically significant differences in the skinfold thickness of the same gender between the urban and rural. (3) The skinfold thickness of facial and suprailiac of urban males, urban females, rural males, rural females was positively correlated with age, and the skinfold thickness of calf was negatively correlated with age. In addition, the skinfold thickness of subscapular of rural males was positively associated with age, while the skinfold thickness of biceps was negatively correlated with age. Conclusion: Compared to adults in the other ethnic groups in China, the skinfold thickness of adults in Zhejiang area is most close to that in Shandong area and Shanxi area and has the characters of North Asian type ethnic groups.
