广西巴马20--110岁世居人群的体型特征

Somatotype characters of 20 to 110 years aborigines in Bama Guangxi

目的：探索世界第5长寿之乡广西巴马县世居人群的体型特征。方法：用Heath-Carter体型法，对992名（男463，女529）20～110岁巴马世居人群的体型进行评价。结果：随年龄增长，男、女内因子值上升至404岁组达最高，而外因子值降至最低，50岁后男、女内因子值逐渐下降，女性明显于男性，而外因子值逐步回升。中因子值男30～、女40～岁组升至最高，后下降；男性体型（3．4-3．6-2．5）以偏内胚层的中胚层体型占优势，女性（5．0-2．9-2．1）以偏中胚层的内胚层体型最多见；与其他群体比较，巴马世居人群男、女内因子值较大，中因子值最小，外因子居中。结论：巴马世居人群皮下脂肪较厚，骨骼细小，肌肉系统发育差、肌量少，体型以小巧匀称为特征。

Objective： To study the somatotype characters of aboriginal adults in Bama Guangxi where is one of the world＇s top five longevity districts. Methods：The somatotypes of 992 aboriginal adults （male 463 and female 529） ranging from 20 to 110 years in Bama of Guangxi China were analyzed with Heath-Carter somatotyping method. Results： The endomorphy increased with the aging in males and females and reached the top in ≥omorphy descented with the aging in the male and female and reached the base in group 40-49 years and then increased with the aging after 50 years. The mesomorphy reach the top in 930 years group in the male and in ≥40 years group in the female, and then descented respectively. The somatotypes were significantly different in the male and female, and the mesomorphy with leaning endomorphy （3. 4-3. 6- 2.5） was major somatotypes in the male and the endomorphy with leaning mesomorphy （ 5. 0-2. 9- 2. 1 ） in the female. Compared with other aborigines in the world, the endomorphic factor was higher, the mesomorphie factor was least and the ectomorphic factor was medial in the male and the female. Conclusion： The somatotype characters of aboriginal adults in t3ama Guangxi are hypodermic fatty thicker, skeleton thiner, muscle undeveloped and the body stature is minor and symmetrically.
