영문 초록

Purpose: The purpose of this study was to identify factors affecting reversion to normal cognition and progression to dementia from mild cognitive impairment (MCI) after 2 years. METHODS: We analyzed data from the 6th and 7th “Korean Longitudinal Study of Ageing (KLoSA)”. A total of 773 participants aged 65 years and above classified as having MCI according to the Korean Mini-Mental State Examination in the 6th survey were included in the study. Data were analyzed by SPSS 26.0 software using chi-square test, t-test, Mann-Whitney test and logistic regression analysis. RESULTS: Of all the participants, 30.5% reverted to normal cognition, 48.5% remained with MCI, and 21.0% progressed to dementia. Factors such as young age (odds ratio [OR]=0.96, 95% confidence interval [CI]: 0.94-0.99), the absence of diabetes (OR=1.49, 95% CI: 1.01-2.19), and frequent neighbor networks “at least once or twice a month” (OR=2.35, 95% CI: 1.26-4.37), and “at least once a week” (OR=1.63, 95% CI: 1.03-2.56) compared to “never or less than 6 times a year” significantly associated with reversion to normal cognition. Meanwhile, factors such as old age (OR=1.09, 95% CI: 1.05-1.12), low level of perceived socioeconomic status (reference. above middle) (OR=1.59, 95% CI: 1.05-2.41), low levels of instrumental activities of daily living (OR=1.17, 95% CI: 1.05-1.32), and a small number of social activities (OR=0.70, 95% CI: 0.51-0.96) significantly associated with dementia progression. CONCLUSION: The study indicates the necessity of follow-up research for developing interventions that could aid individuals in reverting to normal cognitive function by managing diabetes or encouraging interaction with neighbors and preventing the progression to dementia by improving Instrumental Activities of Daily Living levels or encouraging participation in social activities.
