西双版纳傣族成人的体型

Somatotypes of Dai people in Xishuangbanna

目的：研究西双版纳傣族成人的体型特征.方法：应用Heath-Carter体型法对西双版纳傣族自治州20～75周岁的傣族成人进行体型研究,并与南方其他族群进行比较.结果：傣族男性平均体型为偏内胚层的中胚层体型（3.3-5.5-1.9）,女性平均体型为内胚层-中胚层均衡体型（4.8-5.0-1.4）.线性相关分析显示,傣族男、女体型值的内、中因子与年龄呈正相关,外因子与年龄呈负相关,方差分析显示,内、中、外因子值在年龄组间的差异均具有统计学意义.傣族男、女体型性别间差异具有统计学意义.与南方其他族群相比,傣族男性、女性的体型与贵州布依族比较接近,体型位置距离（SAD）分别是0.62、0.71.结论：傣族成人的体型特征为脂肪较多,骨骼、肌肉较发达,身体线性程度低.

Objective：To analyze the somatotype of the Dai people in Xishuangbanna.Methods：The somatotypes of 402 Dai adults were studied by Heath-Carter method,and the somatotypes were compared between Dai people and other ethnic groups in southern areas.Results：The mean somatotype values of male were 3.3-5.5-1.9,which represented the endomorphic mesomorph category.The mean somatotype values of female were 4.8-5.0-1.4,which represented the endomorphmesomorph category.The linear correlation analysis showed that endomorphy and mesomorphy were positive with age,while ectomorphy was negative with age both in male and female.One-way ANOVA showed that the difference between endomorphy,mesomorphy and ectomorphy with ages were statistical significant.The difference of somatotypes between males and females were statistical significant in Dai people.Compared with other ethnic groups in southern areas,the somatotype of male in Dai people was closest to Bouyei nationality in Guizhou （SAD=0.62）,and the somatotype of female was also closest to Bouyei nationality in Guizhou （SAD=0.71）.Conclusion：The adults of Dai people have more fat with developed skeleton muscles and lower linear degree.
