This study evaluates the factors related to nutritional status of elderly, to be used as a basic reference for effective prevention program. Methods : The cross-sectional study evaluates the nutritional status of community-living elderly, aged 60 and older, in a Korean rural community. The subject were selected from a two stage cluster sampling. Questionnaire contained demographics, the Mini-Nutritional Assessment(MNA), Mini-Mental Status Exam-Korean(MMSE-K), Geriatric Depression Scale(GDS), IADL, Social support network, and dietary patterns. T-test and hierarchical regression models were constructed to explore the factors related to nutritional status. Results : Mean age was with 101 male subjects and 200 female subject. The MNA score revealed 41.5% of subjects who were at risk of malnutrition. The mean MNA score showed significant differences in terms of following factors: gender, age, education, marital status, income, expenditures, MMSE-K, GDS, social support, instrumental support, regularity of meal, changes in taste, satisfaction in food, unbalanced dietary habit, number of family members sharing the meal, IADL, presence of disease, number of medications(p<0.05). Multiple regression analysis revealed that demographic characteristics explained 7.5% of nutritional status, social support network 6.7%, mental disease 25.3%, dietary pattern 23.8%, and physical disease 22.2% correspondingly. Whole model explained 45.1% of nutritional status. The significant variables were the number of medications, presence of stress, unbalanced dietary habit, regularity of meal, instrumental support, depression, cognition, and satisfaction in food(p<0.05). Conclusion : Mental and physical state, dietary pattern, social support network, demographic characteristics were related to nutritional status.
