AnnotationThe study reports the methods and initial findings of the first longitudinal study of Alzheimer's disease (AD) and dementia in China. A sample of 5,055 non-institutionalised older people in Shanghai was tested directly during the first phase of the study using a Chinese version of the Mini-Mental State Examination (MMSE). The sampling design and data collection procedures are described. Overall, some 4.1% of over 55s may be classified as having severe cognitive impairment; 14.1% are mild cases. The rates for females are higher than for males by a ratio of 3.75 in the severe category and 2.6 in the mild group. Within each age group, cognitive impairment rates vary by education. Indeed, educational attainment has a highly significant reverse relationship with prevalences of cognitive impairment (severe vs others). On the other hand, where educational attainment was controlled for in the logistic regression model, sex was significantly associated with prevalence of cognitive disorders for the age groups 65-74, and 75 and over, but not for the 55-64 group. Cross-tabulations of impairment according to marital status, economic status, and health-related problems are also presented. (RH).
