Cognitive Health Promotion Project in the Community

Cognitive Health Promotion Project in the Community

This study was based on baseline data derived from a large prospective study called the Suwon Project (SP), a cohort comprising random clustering samples of elderly people, all of whom are ethnic Koreans aged over 60 years.

There is growing evidence supporting the protective effect of health behaviors against cognitive decline and dementia in older persons. With this increasing evidence and a better understanding of the underlying mechanisms, lifestyle modification is likely to be increasingly promoted as a convincing strategy for maintaining cognitive health in later life.

The study protocol included cognitive screening through the Korean version of the Mini-Mental State Examination (K-MMSE), which has been validated for the Korean-speaking population ({YW, 1997 #88}Kang YW et al., 1997), recording of the subject's medical history. A Korean study in the community defined the cut-off point of K-MMSE score during the screening of dementia as 17/18 points; the sensitivity and specificity of the findings were 91% and 86%, respectively ({YW, 1997 #88}Kim et al., 2003). Based on these results, we defined cognitive impairment (CI) as the group that had a K-MMSE score lower than 17, and not cognitive impairment (NCI) was defined as the group that had a K-MMSE score higher than 18.
