Abstract

This study was conducted to determine the levels of cognitive impairment (MMSE-K) among centenarians, and to reveal their association with related variables. The study subjects were 268 centenarians who received medical check-ups from the National Health Insurance Corporation during the period of 2016-2017. The levels of cognitive impairment were significantly reduced among females as well as those living with spouses and children, lower monthly income, lower BMI and individuals who engaged in smoking and alcohol consumption without regular exercise relative to their respective counterparts. The risk of definitive cognitive impairment in study subjects was significantly higher among women (ORs=9.85, 95% CI=2.88-33.59) than men and was lower in obese group (ORs=0.25, 95% CI=0.07-0.86) than in low weight groups, as well as in non-smoking (ORs=0.30, 95% CI=0.10-0.83) than smoking groups. The factors influencing the cognitive impairment of study subjects were sex, living status, monthly income, BMI and smoking status. Taken together, these results suggest that the levels of cognitive impairments among centenarians differed significantly in response to socio-demographic characteristics and health related variables. Especially, the levels of cognitive impairments decreased among those with poor health related variables such as smoking, alcohol consumption and regular exercise.

본 연구는 우리나라 100세 이상 고령자의 인지기능장애 수준을 알아보고 그의 관련요인을 규명해 보고자 시도하였다. 연구대상은 2016년부터 2017년까지의 기간 동안에 국민건강보험공단에서 시행하는 건강검진 및 장기요양 인정조사를 받은 주민등록상의 100세 이상 고령자 268명(남성 132명, 여성 136명)으로 하였다. 연구결과, 조사대상 100세 이상 고령자의 인지기능장애수준은 남성보다 여성에서(p=0.000), 혼자 산다는 군보다 배우자나 자녀와 함께 산다는 군에서(p=0.019), 가정의 경제 상태가 낮을수록(p=0.001), 비만도가 낮을수록(p=0.000), 비흡연군보다 흡연군에서(p=0.000), 비음주군보다 음주군에서(p=0.013), 규칙적인 운동을 한다는 군보다 하지 않는다는 군에서(p=0.020)에서 유의하게 낮았다. 조사대상 100세 이상 고령자의 확정적 인지기능장애가 나타날 위험비는 남성보다 여성(ORs=9.85, 95% CI=2.88~33.59)에서 유의하게 증가하였고, 저체중군보다 비만군(ORs=0.25, 95% CI=0.07~0.86)에서, 흡연군보다 비흡연군(ORs=0.30, 95% CI=0.10~0.83)에서 유의하게 감소하였다. 조사대상 100세 이상 고령자의 인지기능장애에 영향을 미치는 요인으로는 성, 거주상태, 경제상태, BMI, 흡연상태가 유의한 변수로 선정되었다. 이상과 같은 연구결과를 보면, 조사대상 100세 이상 고령자의 인지기능장애 수준은 여러 인구사회학적 및 건강관련행위특성 변수에 따라 유의한 차이를 보이고 있었다. 특히 흡연, 음주 및 규칙적인 운동 등과 같은 건강관련행위특성이 좋지 않은 군에서 인지기능 수준이 저하됨을 시사하고 있다.
