额济纳土尔扈特蒙古族的皮褶厚度

The Skinfold Thickness of Ejina Torghut Mongolian

采用随机取样方法,于2017年9月在额济纳旗对土尔扈特蒙古族196例(男84例,女112例)成人的面颊皮褶、肱二头肌皮褶、肱三头肌皮褶、肩胛下皮褶、髂前上棘皮褶、髂嵴上皮褶和小腿内侧皮褶7项皮褶厚度进行了测量,分析了皮褶厚度随年龄变化的规律,对皮褶厚度进行了性别间的u检验,并与我国部分族群的皮褶厚度进行比较和聚类分析.结果显示,(1)性别间皮褶厚度进行比较,差异具有统计学意义;除面颊皮褶厚度外,女性其余各项皮褶厚度均高于男性.(2)同年龄组性别间体脂百分含量(%)比较,女性各项体脂百分含量(%)均高于男性.(3)随年龄增长,土尔扈特蒙古族在60岁以前,髂前上棘皮褶和髂嵴上皮褶逐渐变厚.(4)土尔扈特蒙古族男性肩胛下皮褶最厚,肱二头肌皮褶最为菲薄,躯干部的皮下脂肪厚度高于四肢.女性则是肱三头肌皮褶最厚,肱二头肌皮褶最为菲薄.(5)与其他14个族群比较,除髂前上棘皮褶外,土尔扈特蒙古族其余各项皮褶厚度均高于其他族群.土尔扈特蒙古族皮褶厚度具有北亚类型族群的特征.

Using random sampling method,7 skinfold thicknesses values of facial,triceps,biceps,subscapular,suprailiac and calf of 196 adults(84 males,112 females)of Torghut Mongolian in Ejina were measured in September 2015.And analyze the variation features of skinfold thickness varies with increased age.The u test was performed on the skinfold thickness between male and female,compared and cluster analysis the skinfold thickness values between Torghut Mongolian and other ethnic groups in China.The results showed that,(1)The thickness of the sex skinfold was compared,differences were statistically significant.In addition to the facial skinfold thickness,the other skinfold thickness of female was higher than that of male.(2)Comparison of the percentage of body fat percentage in the same age group(%)the percentage of female body fat was higher than that of male.(3)With the increase of age,before the age of 60 of Torghut Mongolian,the subscapular and suprailiac skinfold thickness increasing gradually.(4)Torghut Mongolian male subscapular skinfold thickness for most,the most thick biceps skinfold,the thickness of subcutaneous fat in the trunk was higher than that in the limbs.The female is the triceps skinfold thickness for most,the most thick biceps skinfold.(5)Compared with the other 14 ethnic groups,in addition to the a suprailiac skinfold,Torghut Mongolian the rest of the skinfold thickness were higher than those of other groups.The thickness of the Mongolian skinfold has the characteristics of the North Asian species.
