广西毛南族成年女性皮褶厚度与年龄变化

Skinfold change with aging in adult females of Maonan nationality in Guangxi province of China

背景：使用皮褶厚度计测量皮褶厚度来分析皮下脂肪分布和发育状况的方法简单、经济，故被学术界广泛采用。目的：调查广西毛南族成年女性体脂发育水平和年龄变化。设计、时间及地点：整群抽样调查，于2006—09／10在右江民族医学院基础学院解剖学教研室完成。对象：采用随机抽样法抽取了在广西环江县居住10年以上且双亲均是毛南族的健康女性533名，年龄25～75岁，每5岁间隔为1个年龄组，分为10组。方法：由专人负责按《人体测量手册》进行测量和计算，测量工具为仿日本荣式改良皮褶厚度计，将测量所得的数据在微机中建立数据库。主要观察指标：测量不同年龄组毛南族成年女性的肱三头肌皮褶厚度、肩胛下皮褶厚度、髂前上棘皮褶厚度及腓肠肌皮褶厚度，并与国内其他群体进行比较。结果：①毛南族成年女性的躯干皮下脂肪厚于四肢。②毛南族成年女性的皮褶厚度增长到最大值后，随年龄增加而下降。⑨与国内其他少数民族相比，广西毛南族成年女性的皮下脂肪发育逊于达斡尔族、乌孜别克族，优于布依族。结论：广西毛南族成年女性皮褶厚度随年龄增长呈波浪式变化，其发育情况介于布依族和侗族、达斡尔族、乌孜别克族之间。

BACKGROUND： Skinfold thickness instrument was used to analyze the distribution and development of subcutaneous fat. This method is simple, economic, and widely used. OBJECTIVE： To investigate the body fat development and age changes in female adults from Maonan nationality in Guangxi province. DESIGN, TIME AND SETTING： The cluster sampling investigation was performed at the Department of Anatomy, Basic College, Youjiang Medical College for Nationalities from September to October 2006. PARTICIPANTS： Using random sampling method, 533 healthy adult females of Maonan nationality and aged 25-75 years were selected from Huanjiang county of Guangxi province. They all live in Huanjiang count for over 10 years and their parents were also Maonan nationality. Taking five years were served as a group, totally 10 groups. METHODS： The indexes were measured and calculated by professionals according to Handbook of Human Measure. The equipment was modified skinfold thickness instrument. The database was set up in computer. MAIN OUTCOME MEASURES： Skinfold thickness of triceps brachii, anterior superior iliac spine, inferior angle of scapula and gastrocnemius. Four indexes were compared with other groups in China. RESULTS： The torso skinfold was thicker than limb ones. Skinfold thickness decreased with age after it came to the maximum. Compared with other minornationalities, the skinfold of Maonan adult females in Huanjiang of Guangxi province was thinner than Daur and Uzbek, but thicker than Bouyei nationality. CONCLUSION： The skinfold thickness of Chinese Maonan nationality in Guangxi province has a wavy change. It is thicker than Bouyei nationality and thinner than those in Dong nationality and Daur nationality and Uzbek nationality.
