布朗族成人皮褶厚度特征的研究

Study on Skinfold Thickness of Blang Nationality Adults

为了探讨布朗族成人皮褶厚度值的年龄变化规律及其与其他族群的差异,本文采用随机抽样的方法,对云南省604例(男性248例、女性356例)布朗族成人的6项皮褶厚度进行测量,并运用Excel(WPS)和SPSS 19.0软件对数据进行统计,结果表明:(1)布朗族男性的髂嵴上皮褶最厚,6项皮褶厚度与年龄不存在相关性(P>0.05);布朗族女性的髂嵴上皮褶最厚,各项皮褶厚度基本在40~<50岁达到最大,女性的肱三头肌皮褶、肩胛下皮褶、髂嵴上皮褶和小腿内侧皮褶厚度均与年龄呈负相关。(2)与国内其他族群比较,布朗族上肢和躯干的皮褶厚度中等,下肢的皮褶厚度偏低。(3)聚类分析结果显示,布朗族的6项皮褶厚度值与西南地区少数民族更为接近。

To study the variation of skinfold thickness of Blang nationality adults with increased age and their differences with other groups, 604 Blang adults （248 males, 356 females） in Yunnan Province were surveyed using the random sampling method by measuring their 6 items of skinfold thickness. Excel （WPS） and SPSS 19.0 software were used for statistical analysis. The results drawn from these studies are shown below. The anterior superior iliac spine skinfold is the thickest for the Blang nationality male with no correlation between the 6 items of skinfold thickness and age. The suprailiac skinfold and anterior superior iliac spine skinfold are the thickest for the Blang female with their 6 items of skinfold being the thickest at the age of 40--~ 50. The female skinfold thicknesses for triceps, subscapular, anterior superior iliac spine and calf are negatively correlated with age. Compared with other ethnic groups, the Blang nationality male＇s skinfold thicknesses are in the middle level for the upper limbs and abdominal and in the low level for back and lower limbs, however, the Blang nationality female＇s skinfold thicknesses are in the middle level for limbs and back and in the high level for abdominal. The results of cluster analysis showed that the 6 items of skinfold thickness of the Blang are similar to the rural Han nationality.
