PYLL DALY和HeaLY在疾病负担研究中的作用分析

目的：探讨PYLL、DALY和HeaLY在疾病负担研究中的作用及其特点。方法：以汉中市农村脑卒中监测基地为基础，采用标准的计算方法，计算PYLL、DALY和HeaLY。结果：汉中市农村人口因患脑卒中所致PYLL为220．0年，男性和女性分别占59％和41％；DALY为598．88年，因死亡和失能损失分别占78．7％和21．3％，男性和女性分别占57．3％和42．7％：HeaLY为301．73年，因死亡和失能损失分别占73．5％和26．5％。结论；PYLL适用于评价早死的疾病；DALY适用于评价致残率比较高的疾病，但计算比较复杂；HeaLY是简化的DALY，适用于粗略的估计疾病负担。

Analysis of effects of PYLL, DALY and HeaLY on study of burden of diseases

To analyze the effects of PYLL, DALY and HeaLY on study of burden of diseases. Methods: Based on the data from the stroke surveillance base for Hanzhong rural population, standard formulas were used to calculate PYLL, DALY and HeaLY. Results: The PYLL of Hanzhong rural population by stroke was 220.0 years and the proportions of male and female were 59% and 41 % , respectively; DALY was 598.88 years, the proportions of death and disability were 78.7 % and 21.3 % and male and female were 57.3 % and 42.7 % , respectively; HeaLY was 301.73 years and the proportions of death and disability were 73.5 % and 26.5%, respectively. Conclusion: PYLL is suitable for evaluation of burden of diseases caused early death; the calculation of DALY is complicated and suitable for evaluation of chronic diseases with disability; HeaLY is suitable for simple evaluation of burden of
