Relationship between Nutritional Status Evaluated by Mini Nutritional Assessment Short-Form and Activities of Daily Living after 1 Year in Community-Dwelling Older Adults Using Outpatient Rehabilitation

Abstract

Objective

This study aimed to investigate the association between nutritional status assessed by the Mini Nutritional Assessment Short-Form (MNA-SF) and activities of daily living (ADL) after 1 year and changes in ADL among community-dwelling older adults.

Methods

This study included 95 community-dwelling older adults using outpatient rehabilitation (74.7% female). ADL was assessed using the Barthel index (BI), and the MNA-SF was used to assess nutritional status. Multiple regression analysis was performed with the BI after 1 year as the objective variable and MNA-SF, age, sex, updated Charlson comorbidity index, number of medications, body mass index, Food Intake Level Scale (FILS), and baseline BI as independent variables. Logistic regression analysis was performed with improvement or deterioration in ADL as the objective variable.

Results

The results of multiple regression analysis with BI after 1 year as the objective variable indicated that baseline BI, FILS, and MNA-SF were significant variables (R² = 0.835). The results of the logistic regression analysis with ADL improvement/deterioration as the objective variable indicated only MNA-SF as a significant variable (odds ratio: 0.663 [95% CI: 0.528–0.923]).

Conclusions

These results indicate that the MNA-SF was related to changes in ADL and ADL after 1 year among community-dwelling older adults.
