Abstract:

Objective  To study the development degree of subcutaneous fat of Guizhou dong adult.    Methods The human body measurements, in October 2015 and November 2018 to Guizhou Rongjiang treble Dongzhai Miao and Dong autonomous county of Dong adult biceps skinfold, triceps skinfold, subscapular skinfold, suprailiac skinfold, supraspinale skinfold, calf skinfold six skinfold were performed, including 951 cases (male 333, female 618).   Results  The skinfold thickness of the trunk of Dong adults in Guizhou was greater than that of the limbs. The maximum values of the six skinfolds of male and female were found in 45-59 years old group. The minimum values of the biceps skinfold, suprailiac skinfold, supraspinale skinfold and calf skinfold of male were found in 2044 years old group, and the minimum values were found in 60-80 years old group of female. Subscapular skinfold, suprailiac skinfold and calf skinfold were positively correlated with age in males (0.01 <P< 0.05), while biceps skinfold, triceps skinfold, subscapular skinfold and calf skinfold were negatively correlated with age in females (P< 0.01). There were statistically significant differences in the 6 skinfolds between the sexes. The skinfold of females was all thicker than that of males. The percentage of body fat of female was higher than that of male. The result  of cluster analysis of 13 ethnic groups showed that the six skin fold thicknesses of Dong were all smaller than  those of northern ethnic groups, and close to those of southern ethnic groups. Conclusion  The subcutaneous fat development in Dong is relatively high, which is similar to that in Zhuang and Dong nationalities. The skinfold thickness of Dong nationality has the characteristics of southern ethnic groups.
