进驻海拔4300m不同时间部分体测量指标对比观察

Contrast of Partial Human Body Measurement Index among Persons Stayed at 4300 Meters' Altitude for Different Time

目的探讨进驻海拔4 300 m不同时间对人体部分体测量指标的影响。方法对534名青年官兵在进驻海拔4 300 m前、进驻半年、1年、3年及返回平原半年时,分别检测身高、体质量、脉搏、血压、血氧饱和度、体脂量及上臂肌围。结果上高原后不同时间与上高原前比较,除身高外,其余各项指标检测参数间差别均有高度显著性(P<0.01);进驻1年与进驻半年和进驻3年与进驻1年比较,除身高和血氧饱和度外,其余各项指标检测参数间差别均有高度显著性(P<0.01);下高原半年后各项指标均基本恢复到上高原前水平。结论进驻海拔4 300 m以上地区不同时间对人体部分体测量指标影响较大。

Objective To study partial human body measurement index among the persons staying at an altitude of 4 300 meters fol different time. Methods A total of 534 young servicemen were measured for stature, avoirdupois, sphygmus, blood pressure, SaO2, body fatness and arm muscle circumference before they were up to high altitude, after they stayed above an altitude of 4 300 meters for half a year, one and three years, and half a year when they returned to plain. Results The metrical indexes at high altitude for different duration were significantly different, when compared with that at plain except stature （P 〈0.01 ）. The metrical index after they stayed at high altitude for one year was significantly different from that for half a year and threee years except stature and SaO2 （ P 〈 0.01 ）. Every metrical index resumed to normal after they returned to plain for half a year. Conclusion There is significant influence on partial human body measurement indexes for thee who stay at the area of 4 300 meters＇altitude.
