摘要
为探讨高原环境及脱适应对人体健康的影响,本文以曾长期移居青海高原(海拔2260~4200m)后返回内地(平原)以及仍留居高原的9542名离休干部为研究对象,对其全部死亡资料(579人)进行Ridit分析,结果显示:总的趋势是返回内地的平均Ridit值比留居高原的平均Ridit值要大(P<0.01),高原居住地海拔越高,返平原时年龄越大,平均Ridit值越小(P<0.01)。说明返回内地年龄以轻些为宜。
We carried out this study for the purpose of finding out the effect of altitude hypoxic environment in plateau and in plateau desacclimatization on the health.This investigation selected 9542 cases of residents,who had lived at Qinghai plateau (with an altitude of 2260 ̄4200m) for a long period,including both returned to plain and still lived at high altitude after they retired.The auther made a Ridit statistical analysis for all the death data (579 cases).The results showed that the mean Ridit value of the plain group was higher than that of the high altitude group ( P <0 01).The higher the elevation of living place was and the older the years was when they returned to plain,the smaller the mean Ridit value was ( P <0 01).The results showed that the younger the years of returning to plain was better for the people′s health.
