青海省离休干部生存率分析

THE ANALYSIS OF SURVIVAL RATE OF QINGHAI PLATEAU 'S RETIREES

对1987年底以前离休的10668名老干部离休后返回内地与留居高原的两组生存率分析,结果男性累积死亡率6.07％高于女性的1.96％,内地组高于高原组(P<0.01),密度死亡率的调整率内地组低于高原组。寿命表法生存率动态分析,总的趋势是离休后两年以内高原组高于内地组,两年以后各年内地组高于高原组,分组比较,六州50岁组内地组明显高于高原组(P<0.01)。实际死亡数与期望死亡数之比,除西宁海东60岁组外,高原组均有超额死亡,内地组实际死亡数均低于期望死亡数。

The analysis for the survival rate of 10668 retirees who are retirement before 1987 and live on the Plateau or low elevation ar eas after their retirement indicated; The mortality of males was 6.07%, that of females was 1.96%; the former was higher than the lal ter ( P<0.01). The standardized density mortality in the low elevation group was lower than that in Plateau. Based on the life table, observation of series showed; That the survival rate in the Iow elevation group and in the plateau group was basically identical during the fist two years after their retirement; after three years, there was a trend that the survival rate in the low elevation group was higher than that in the Plateau group.The comparison between area groups and between age groups indicated that the survival rate in low elevation group was higher than that in the plateau group tor the 50 ages retirees who worked at six high elevation prefectures before their retirement (P<0.0l).The comparison for the real death figures with the expected value showed that there was above quota of death in the plateau groups except su-piateau 60 years group.We preliminary conclude that it would be better for the retirees of Qinghai plateau to reside in low elevation area.
