Objective To study the adult skinfold thicknesses of Han of Shanxi province. Methods Using the random sampling method, the skinfold thicknesses of the facial, triceps,biceps, subscapular,suprailiac and calf regions of 803 Han adults ( 150 urban males and 153 urban females,251 rural males and 249 rural females ) in Qi county of Shanxi province were studied .The skinfold thickness characters of Han adults in Shanxi with the increasing age was analyzed. Results The skinfold thickness of females was thicker than males ,and there were statistically significant differences between genders. The skinfold thickness of urban males was thicker than rural males,and there were statistically significant differences between urban areas and rural areas. The 6 skinfold thicknesses changed with the increasing age.Correlation analysis showed that the skinfold thickness of the face was thickening and of the calf was thinning. In addition, female skinfold thickness of the subscapular region was increasing as well .Conclusion Skinfold thickness of Han in Shanxi has the characters of North Asian ty
