Abstract
[한글]목적 : 이 연구는 노인 인구에서 ApoE 유전자형이 대사증후군 및 대사증후군의 하부진단요소들과 인지장애와의 관계에 미치는 영향을 알아보기 위해 이루어졌다.방법 : GDEMCIS (Gwangju Dementia and Mild Cognitive Impairment Study) 자료 중 60세 이상 2944명 (남자 883명 여자 2061명)이 분석에 이용되었다. 대사증후군은 modified NCEP ATP III (National Cholesterol Education Program Adult Treatment Panel III)의 진단기준에 의해 평가되었다. 인구사회학적 요인, 현재 및 과거 질환력, 약물력, K-MMSE (Korean version-Mini Mental State Examination)를 조사하였다. ApoE 유전자형을 조사하여 대사증후군과 관련된 요인들을 분석하였다. 이 연구는 연구윤리심의위원회의 승인을 받았다.결과 : 대사증후군은 전체 대상자 중에서 53.8%였으며, 남자 중에서 36.8%, 여자 중에서 61.1%였다. 다중로지스틱회귀분석에서 대사증후군은 나이, 성별, 교육수준, 현재 흡연력을 보정하였을 때 인지장애 (K-MMSE score < 18)와 통계적으로 유의한 관련이 없었다. 다중로지스틱회귀분석에서 대사증후군의 5개 하부진단요인 중 ApoE ε4 대립유전자가 존재할 경우에만 나이, 성별, 교육수준, 현재 흡연력을 보정하였을 때 수축기혈압 또는 혈중 중성지방이 높을수록 (OR = 1.03, 95% CI = 1.00-1.06; OR = 1.006 , 95% CI = 1.00-1.01) 또는 혈중 고밀도지단백 콜레스테롤이 낮을수록 (OR = 0.96, 95% CI = 0.92-1.00) 인지저하 (K-MMSE score < 18)의 위험도를 높였다.결론 : 이는 노인 인구에서 ApoE ε4 대립유전자가 존재할 경우 수축기 혈압과 혈중 중성지방 및 고밀도지단백 콜레스테롤이 인지기능과 관련이 있음을 의미한다.

[영문]Objective : The purpose of this study was to find out the effect of the ApoE genotype on the relationship between metabolic syndrome and its diagnostic components and cognitive impairment in the elderly.Methods : A total of 2944 subjects (883 men and 2061 women) aged over 60 years were analyzed from the data of GDEMCIS (Gwangju Dementia and Mild Cognitive Impairment Study). The metabolic syndrome was assessed as defined by the modified NCEP ATP III (National Cholesterol Education Program Adult Treatment Panel III). We examined demographic characteristics, current and past illness history, drug history, K-MMSE (Korean version-Mini Mental State Examination). We also examined ApoE genotype and analyzed associated factors with metabolic syndrome. This study was approved by the institutional review board.Results : Metabolic syndrome was present in 53.8% of the subjects (36.8% of men and 61.1% of women). On multiple logistic regression analysis, metabolic syndrome was not associated with cognitive impairment (K-MMSE score < 18) adjusted for age, sex, educational level, current smoking status. On multiple logistic regression analysis with the 5 diagnostic components of metabolic syndrome, as systolic blood pressure or the level of blood triglyceride was higher (OR = 1.03, 95% CI = 1.00-1.06; OR = 1.006 , 95% CI = 1.00-1.01), or the level of blood high density lipoprotein (HDL) cholesterol was lower (OR = 0.96, 95% CI = 0.92-1.00), the risk of cognitive impairment increased after adjusting for age, sex, educational level, current smoking status in the presence of ApoE ε4 allele.Conclusion : These results suggest that systolic blood pressure, blood triglyceride and HDL cholesterol may affect cognitive function in the elderly in the presence of ApoE ε4 allele.
