成都市成人伤残调整期望寿命研究

The Study on Disability-Adjusted Life Expectancy of Adults in Chengdu

目的了解成都市成人健康状况。方法采用多阶段分层随机抽样法,对成都市1 782名18岁以上常住人口进行健康状况调查,使用CHOPIT模型校正自报健康的切点位移偏倚,Sullivan法计算伤残调整期望寿命。结果成都市成人20岁组期望寿命(LE)为58.9岁,伤残调整期望寿命(DALE)为39.6岁;各年龄段女性LE高于男性,但健康测度低于男性,失能导致的寿命损失(DLE)占LE的比例(DLE/LE)高于男性;DLE/LE随着年龄的增加而增加,从20岁组0.33上升到85岁组0.54。结论失能对女性健康影响大于男性,失能对老年人健康的影响大于年轻人。

Objective To learn the health status of adult in Chengdu by disability-adjusted life expectancy. Methods A health status questionnaire survey was carried out in 1 782 permanent residents aged older than 18 years in Chengdu, using stratified multi-stage cluster sampling. Cut point shift bias of self-reported health was adjusted by CHOPIT model. Sullivan method was applied to calculate adults＇ healthy life expectancy. Results The life expectancy （LE） of 20-yrs-old group was 58.9 years old and the disability-adjusted life expectancy （DALE） was 39.6 years old. The LEs of the female all were higher than those of male in different age groups, but the female＇ s health measure was lower and the proportion of DLE/LE was higher than that of the male. DLE/LE increased with age, the ratio was 0.33 in 20-yrs-old group and 0.54 in 85-yrs-old group.
