目的 探讨中国壮侗语族族群成人的体型特征。  方法 采用 Heath-Carter体型法，对壮侗语族15个族群9965（男性4312，女性5653）例进行体型研究。  结果 壮侗语族族群男性平均体型值为4.1-5.2-1.9，属于偏内胚层的中胚层体型，女性平均体型值为5.5-4.9-1.3，属于偏中胚层的内胚层体型。除内因子和SAM外，男性各年龄组身高、体重、中因子、外因子、HWR均大于女性。壮侗语族群性别间3个年龄组体型差异均有统计学意义。男性、女性体重、身高、外因子均与年龄成负相关，内因子与年龄成正相关，男性中因子与年龄不相关，女性中因子与年龄成正相关。男性、女性3因子值年龄组间差异均具有统计学意义。  结论 壮侗语族族群男性、女性随年龄增长体型有明显变化，在南方民族中具有身体线性度低，骨骼、肌肉发达，体脂丰满的体型特点。

Objective To explore the somatotype characteristics of Zhuang-Dong ethnic groups in China.   Methods The Heath-Carter somatotyping method  was used to study the somatotypes of 9965 (male 4312, female 5653) cases from 15 Zhuang-Dong language groups.   Results The average somatotype of males in the Zhuang-Dong ethnic group were 4.1-5.2-1.9, which belonged to the mesodermal somatotype of partial endoderm, and the mean somatotype of women were 5.5-4.9-1.3, which belongs to the endoderm somatotype of partial mesoderm. Except for endomorphy factor and SAM, height, weight, mesomorphy, ectomorphy and HWR of all age groups of males were greater than those of females. There were statistically significant differences in somatotype among the three age groups among the sexes of the Zhuang-Dong language group. The weight, height, and ectomorphy of men and women were negatively correlated with age, and endomorphy were positively correlated with age. Among them, the male mesomorphy was not correlated with age, and the female mesomorphy was positively correlated with age. The differences between male and female three-factor value age groups were statistically significant.   Conclusion The somatotype of male and female of Zhuang-Dong ethnic group has obvious changes with the increasing of age, and the southern ethnic group has the characteristics of low linearity, well-developed bones and muscles, and plump body fat.
