| Annotation | The aim of this study was to analyse the prevalence of dementia and its major subtypes - Alzheimer Disease (AD) and vascular dementia (VaD) - among the population aged 60 years and over in China from 1980 to 2004. Epidemiological investigations on dementia in China published in journals and covering the period from 1980 to 2004 were identified manually and online by using CBMDISK, Chongquin VIP database and CNKI database. Those reported in English journals were identified using MEDLINE. Selected studies had to describe an original study defined by strict screening and diagnostic criteria. The fixed effects model or random effects model was employed according to statistical test for homogeneity. 25 studies were selected, the statistical information of which was collected for systematic analysis. Results showed that AD and VaD were the two major subtypes of dementia in China, and the pooled prevalence of AD and VaD for the population aged 60+ was 1.6% and 0.8% respectively. There was a higher prevalence of AD in the illiterate older population (3.2%) than in those who received years of education. The chronological prevalence of AD increased significantly from 1980 to 2004. In southern and northern China, the prevalence of AD was 2.0% and 1.2% respectively, while VaD was 0.6% and 1.1% respectively. In the last 24 years, AD and VaD have been the two major subtypes of dementia in China. The prevalence of AD may be affected by sex, education, occupation or age. The prevalence of VaD, which was higher in northern than in southern China, seems not be affected by age, sex or education. (KJ/RH). |
