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.
