Abstract: 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.
