Abstract

Mini-Mental State Examination (MMSE) and naming tests have been used clinically as screening and diagnostic tools for mild cognitive impairment and dementia. Researches in other countries have reported that residential areas would affect one's cognitive abilities. In Korean, however, there was no systematic studies on geographical influences to cognitive ability among a sample of urban/rural residents. The aim of this study was to investigate the effect of urban/rural locality of residence on cognitive tests in normal elderly Korean. Residents aged 65 years and older (N=108) were administered the K-MMSE, confrontation/generative naming tests, and medical/socio-demographic interview. When comparing the total number of correct responses between urban residents and rural residents, the performances of rural group were significantly worse than those of the urban group in K-MMSE. Based on the results, our finding suggests that a factor of residential locality should be considered to examine the function and explain the cognitive decline in rural community-dwelling elders.

간이정신상태검사나 이름대기검사는 경도인지장애나 치매를 감별하고 진단하기 위한 도구로서 임상에서 널리 사용된다. 표준화 검사로부터 얻어진 많은 자료는 대부분 도시 지역 노년층의 인지기능에 대한 정보를 제공한다. 국외 연구를 통하여 거주지의 위치가 인지기능검사의 수행에 미치는 영향력이 보고되고 있다. 그러나 국내에서는 인지기능검사의 수행력에 영향을 주는 도시/농촌 거주지역 효과에 대한 체계적 연구가 부족하며, 농촌 지역 노년층의 인지기능 감퇴 특성에 대한 설명도 미비한 실정이다. 본 연구에서는 한국 노년층을 대상으로 인지기능검사에 대한 거주지역 효과를 확인하고자 하였다. 108명의 65세 이상 노인이 연구에 참여하였으며, 대상자는 모두 간이정신상태검사, 대면/생성이름대기 검사, 병력 및 인구통계학적 정보에 대한 설문을 수행하였다. 도시 거주자와 농촌 거주자의 수행력을 비교한 결과, 간이정신상태검사에서 농촌 거주자의 수행력 저하가 발견되었다. 이러한 결과는 농촌 지역 노년층의 인지기능을 검사하고 수행력 저하를 설명하는데 있어서 거주지역적 요인이 면밀히 고려되어야 함을 시사한다.
