壮侗语族族群的皮褶厚度

Skin fold thickness of the Zhuang-Dong language ethnic group

为探究壮侗语族族群的皮下脂肪发育特征,采用随机抽样方法,在海南、贵州、湖南、广西、云南等地测量了15个族群共10359例(男性4515例,女性5844例)成人的6项皮褶厚度值.结果表明:①壮侗语族族群女性6项皮褶厚度均大于男性,男性和女性四肢皮褶厚度均薄于躯干和背部.②男性和女性6项皮褶厚度值的年龄组间差异均具有高度统计学意义(P<0.01).男性髂嵴上皮褶厚度与年龄无相关,髂前上棘皮褶厚度与年龄呈负相关,其余4项皮褶厚度均与年龄呈正相关;女性髂前上棘皮褶厚度与年龄呈负相关,肱二头肌皮褶厚度与年龄呈正相关,其余4项皮褶厚度与年龄无相关.③男性四肢皮褶厚度与人均可支配收入相关,女性皮褶厚度与人均可支配收入基本无相关.④主成分分析结果显示壮侗语族族群皮褶厚度与苗瑶语族族群更为接近.

In order to study the growth characteristics of subcutaneous fat in Zhuang-Dong language ethnic group,by using randomsamplingmethod,six skin fold thickness of 10359 cases(4515males and 5844 females)of 15 ethnic groups weremeasured in Hainan,Guizhou,Hunan,Guangxi and Yunnan Province,China.The results were as follows:①The six skin fold thickness of females in Zhuang-Dong ethnic group were significantly higher than those of males.The skin fold thickness of limbs both males and females were slightly thinner than those of the trunk and back.②The differences in the six skin fold thickness values between age groups were highly statistically significant(P<0.01).The males suprailiac skin fold was not correlated with age,while the anterior superior spine was negatively correlated with age,and the remaining four skin folds were positively correlated with age.The females anterior superior spine was negatively correlated with age,biceps skin fold was positively correlated with age,and the remaining four skin folds were not correlated with age.③The skin folds of limbs of males were related to per capita disposable income,while the skin folds of females were not related to per capita disposable income.④The principal component analysis showed that the skin fold thickness of Zhuang-Dong language ethnic group was close to the Miao-Yao language ethnic group.
