Background
Despite rapid development of epidemiology in dementia, reported prevalence in Asia varies among studies and differs from that of Western countries. Few reported the mortality and predictive factors on survival of dementia in Asia, especially China.
Methods
To characterize the epidemiologic pattern of dementia in Shanghai, China, including prevalence and survival, we conducted a cross-sectional, population-based survey among Shanghai residents (≥55 y) and followed a subsample for up to 40 months for survival analysis. A stratified, multistage cluster sampling design was adopted.
Results
Crude and age-standardized prevalence of dementia was 2.99% and 2.66%, respectively, higher in women and increased with age. Prevalence of Alzheimer was higher than vascular dementia. Furthermore, Alzheimer disease was more prevalent in rural areas than in urban,…
