Background: The national prevalence of dementia was 8.40% in 2008. However, there was lack of longitudinal research on risk factors affecting development of dementia in South Korea. The aim of this study was to investigate the risk factors developing dementia in a population of community-dwelling elderly (aged 60 over) participated in the Seoul Dementia Management Programme. Methods: A prospective cohort study with a 3-year follow-up period (N 1⁄4 24,266). A trained nurse evaluated the subjects using Korean version of Mini-mental state examination (KMMSE) to screen cognitive functioning. Scoring 21 or below led to a second examination by a neurologist or psychologist, including the Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV) and a neurological examination, to decide diagnosis of dementia. At baseline, demographic data including comorbidity and healthy lifestyle habits were gathered. Results: The cumulative incidence rate of dementia was 2.9% (n1⁄4 692). To examine the risk factors affecting development of dementia, we performed theCox proportional hazard regression analysis adjusting for age, educational level, marital status, type of health insurance, body mass index, history of stroke, and life style including smoking status and exercise. We found the significant relationships between older age, lower educational level, Medical Aid beneficiaries, elderly with a history of stroke, ever smokers, those who do not exercise and the subsequent development of dementia. Increasing or decreasing body mass index was not risk factor for developing dementia. Conclusions: To the best of our knowledge, this is the first Community-Based Cohort study to investigate the risk factor for incident dementia in South Korea. In order to prepare and cope with Korea’s aging society, further epidemiological studies are needed to establish a strategic and effective dementia management programme.
