Materials and Method: A cross-sectional study utilizing cluster sampling method was performed. Diagnosis of dementia was made clinically. The parameters effecting the presence of dementia were determined by Chi square test, ϕ coefficient and logistic regression model.
Results: The mean age of the total 490 elderly subjects was 71.8. 34.7% of the elderly were illiterate and 12% were living alone. Prevalence of dementia was found to be 12.9%. According to logistic regression analysis with ϕ coefficient, advanced age and cerebrovascular disease increased the prevalence of dementia in the elderly people.
Conclusion: Prevalence of dementia among community-dwelling elderly people is relatively high. We suggest that occurence of a high rate of dementia in the study population may be due to the cumulative effect of several unfavourable risk factors such as poor socioeconomic conditions and poor health status and low level of education.
