Objective: The objective of this study was to determine independent nutritional assessment factors affecting hospitalization due to deteriorating symptoms and to examine nutritional assessment when these factors were substituted for MNA in institutionalized elderly Japanese people. Methods: Eighty subjects (21 men and 59 women, 81.4±9.2 years) were enrolled. Multivariate logistic regression analysis was used to determine independent factors influencing hospitalization during a follow-up period of approximately 1 year. Associations between nutritional assessment using these factors, MNA and anthropometric variables, and dietary intakes were assessed. Results: Twenty-two subjects were hospitalized during the 1-year follow-up period. Body mass index (BMI) < 22kg/m2 (OR=5.68, 95%CI 1.31-24.7), calf circumference (CC) < 29cm (OR=5.75, 95%CI 1.64-20.2), arm muscle area (AMA) ≤ 36cm2 (OR=4.39, 95%CI 1.25-15.4), and arm muscle circumference (AMC) ≤ 21cm (OR=3.00, 95%CI 0.87-10.4) were associated with hospitalization in multivariate analysis. MNA was not associated with hospitalization (malnutrition group OR = 3.69; 95% CI 0.48–28.6). In CC and BMI groups, all anthropometric variables were significantly different such as MNA groups . In BMI groups, anthropometric variables without activities of daily living (ADL) were different. Cumulative hospitalization was only significantly different in 2 CC groups. Conclusion: These results show that CC and BMI are more useful predictors of hospitalization than MNA and are useful as independent nutritional assessment variables in this study.
