Background: Cognitive impairment is important in clinical geriatrics as a mental frailty. The objective of this study was to investigate the factors related with cognitive impairment in Korean elderly.
Methods: We analyzed data from the Korean Longitudinal Study on Aging (KLoSA). A total of 4,165 Korean community-dwelling elderly (＞65 years, male/female 1,739/2,426) at the first wave (2006) of KLoSA were used for analysis. Cognitive function was assessed with the Mini-Mental State Examination Korean version (MMSE-K) through personal interviews by a trained interviewer with Computer Assisted Personal Interviewing (CAPI). Multiple logistic regression analysis was performed among participants to estimate the odd ratios (OR) and 95% confidence interval (CI) for MMSE score＜23. These estimates were controlled for age, sex, education, MMSE score at baseline, alcohol consumption, current smoking, body mass index and disease history.
Results: 2,120 subjects (50.9%) were classified as cognitive impaired (MMSE score＜23). Age, sex, depression score (CESD-10), function (ADL, IADL), education, employment, income, smoking, drinking and BMI was significantly different between normal and impaired cognitive groups. Cognitive impairment ratio after covariates the female was 2.16 (1.63∼2.86), age 70∼74, 75∼79, ≥80 were 3.51 (2.05∼5.99), 2.24 (1.55∼3.24), 1.87 (1.39∼2.52) low (elementary and
no) education groups were 2.77 (1.99∼3.84) and 8.18 (5.66∼11.82) compare to more educated group (≥9 years). Among health related factors, only ADL and IADL was significantly different after multivariates adjustment. Among social activities, number of meeting with friendly people volunteer group activity were significant factors.
Conclusion: Age, sex, depression score (CESD-10), fuction (ADL, IADL), education, ADL, IADL personal and group social activities were significantly related with cognitive decline in Korean elderly.
