杭州市和富阳县6种病失能寿命损失年(YLD)估算的探索

Analysis of Different Methods for Assessing Years Lived with Disability(YLD) in Hangzhou City and Fuyang County

目的 探索失能寿命损失年 (YLD)及权重的估算方法。方法 采用不同标准对 6种疾病的失能权重进行了评估 ,并估算其失能寿命损失年 (YLD)。结果 肺癌和精神分裂症评估得到的权重与世界银行的权重差异明显 ,肺结核和脑卒中差别不明显 ,车祸和白内障的权重与世界银行的权重之间无可比性。结论 此次调查结果 ,无法判断在国内使用六级失能等级标准和七级失能等级标准的明显不同。为中国开展相应类型的研究提供了有价值的信息。

Objective To calculate the number of YLDs for a specific condition to assess the feasibility in China of one part of the process of determining disability weights.Methods Six health conditions with different levels of disability were selected as indictor conditions to assess the method of assigning disability weights.Results The disability weights assigned by these Chinese experts for lung cancer and schizophrenia were significantly different from those estimated by the GBD,the weights assigned for TB and stroke were not significantly different from the GBD values,and there were no comparable GBD disability weights for cataract and traffic accident.Conclusions This study did not find signficant differences in the reliability and validity of the six-level and seven-level disability classification system.The experience of conducting this study provides valuable information on the procedures that will be needed to successfully complete burden of disease studies in China.
