Nutritional risk and cognitive impairment in the elderly.
The purpose of this study was to determine the relationship between nutritional risk and cognitive impairment in the elderly living in the community. Data obtained from 2934 subjects (912 men and 2022 women) aged above 60 years was analyzed from the Gwangju Dementia and Mild Cognitive Impairment Study (GDEMCIS). The study questionnaire comprised demographic characteristics, history of current and past illnesses, drug history, Korean version-Mini Mental State Examination (K-MMSE), and Nutritional Screening Initiative (NSI) checklist. Additionally, we examined the blood pressure, fasting serum glucose level, lipid profile, body mass index, and ApoE genotype. Of the total, 1942 (66.2%) demonstrated good nutritional state (NSI checklist score< or =2) and 992 (33.8%) were at moderate or high nutritional risk (NSI checklist score>2). Multiple logistic regression analysis revealed that moderate or high nutritional risk subjects were associated with an increased risk of cognitive impairment (K-MMSE score< or =17) after adjustment for age, sex, educational level, and Korean version of Short form Geriatric Depression Scale (K-SGDS) score (Odds ratio=OR=1.71, 95%; confidence interval=CI=1.17-2.50). These results suggest that nutritional risk may be associated with cognitive impairment in the elderly.
