Abstract

Abstract

Objective Based on the population attributable fraction (PAF), the ratio of dementia induced by risk factors was estimated to provide early prevention and intervention strategies. Methods To assess the urban-rural differences of risk factors of dementia using Chi-square test in 3 361 persons which are selected using random cluster sampling and 65 years or older. Based on the results from principal components analysis, we calculated the weighted PAF of each risk factor contributing to dementia. Results The overall weighted PAF for dementia risk factors in urban was 39.51%, and the weighted PAF for individual risk factors was hypertension (10.46%), overweight and obesity (9.78%), smoking (5.69%), low education (5.55%), diabetes (3.93%), lack of physical exercise (2.75%) and lack of social interaction (1.35%). The overall weighted PAF for dementia risk factors in rural was 31.66%, and the weighted PAF for individual risk factors was low education (9.21%), hypertension (6.60%), overweight and obesity (4.96%), lack of social interaction (4.94%), smoking (4.44%), diabetes (1.51%). Conclusions There was a significant difference in weighted PAF of each risk factor between urban and rural areas. And prevention and early intervention strategies for dementia should be given different emphasis in urban and rural areas.
