目的 :探讨高原世居者与移居者身体的不同特点。方法 :同时测定阿里地区 (4 30 0m) 2 5名藏族青年和 2 5名汉族青年的部分体指标。结果 :移居汉族青年较世居藏族青年体重、血氧饱和度及肩胛下部皮褶厚度差异不显著 (P >0 .0 5 ) ;身高、收缩压、体脂量、三头肌部及髂部皮褶厚度增高显著 (P <0 .0 5 ) ;脉搏、舒张压、上臂围及上臂肌围增高非常显著 (P <0 .0 1)。结论 :高原世居藏族青年对高原环境的适应明显优于移居汉族青年。
Objectives: To explore the different characteristics of the highland natives and settlers. Methods: The body mass index of 25 Tibetan youth and 25 Han nationality in Ali area (4 30m) were simultaneously determined. Results: There was no significant difference in body weight, blood oxygen saturation and the thickness of the lower scapular skin of migrant Han nationality youth (P> 0.05); height, systolic pressure, body fat, triceps and ilium Skinfold thickness increased significantly (P <0. 05); pulse, diastolic pressure, upper arm circumference and upper arm muscle circumference increased significantly (P <0.01). Conclusion: The adaptation of native Tibetan youth in plateau to plateau environment is obviously better than that of emigrant Han nationality.
