北京市老年性痴呆、帕金森病疾病失能权重的评定

目的：制订中国老年性痴呆（Alzheimer disease,AD)、帕金森病（Parkinson disease,PD)疾病失能等级分类标准，评定北京市60岁以上人群AD、PD的平均疾病失能权重。方法：以全球疾病负担（global burden of diseas,GBD)研究中疾病失能权重的7级分类标准为根据，采用德尔菲法，制订中国AD、PD疾病失能等级分类标准；并根据1997年北京市AD、PD流行病学调查的资料，评定北京市60岁以上人群AD与PD的平均疾病失能权重。结果：北京市60岁以上人群AD的平均疾病失能权重：获得治疗者为0.40，未获得治疗者为0.52;PD的平均疾病失能权重：获得治疗者为0.30，未获得治疗者为0.23。结论：对于AD与PD两种疾病平均疾病失能权重的评定结果与GBD研究中的数据有所不同。

Evaluation on the disability weight of Alzheimer's disease and Parkinson's disease in Beijing

Objective To formulate the classification criteria of disability weight for Alzheimer's disease (AD) and Parkinson's disease (PD) in China and to evaluate the disability weight of AD and PD in population over 60 years old in Beijing. Methods Based on the criteria of Global Burden of Disease (GBD), a seven-grade disability classification was used to develop a new disability classification criteria for AD and PD in terms of Dephi method in China. Using the data from epidemiological survey for AD and PD in Beijing in 1997 and new criteria, mean disability weights of AD and PD in population over 60 years old in Beijing were obtained. Results The mean disability weights of Alzheimer's disease was 0.40 in population over 60 years old who received treatment in Beijing and 0.52 in those without treatment while the mean disability weights of Parkinson's disease were 0.30 in the patient receiving treatment and 0.23 in those without treatment. Conclusion Difference between the result of this study and the data of GBD study in the mean disability weight for AD and PD was noticed.
