Objective: To clarify the relationship between
improvement in the Geriatric Nutritional Risk Index
(GNRI) and improvement in the Functional
Independence Measure (FIM).
Methods: The subjects were 155 patients aged 65
years or older selected among stroke patients admitted
to a Kaifukuki Rehabilitation Ward. Seven items,
including GNRI at hospital admission and degree of
GNRI improvement, served as independent variables.
For multiple regression analysis, motor FIM score at
hospital discharge was the dependent variable. For
multiple logistic regression analysis, motor FIM gain
(1:13 points or more, 0:12 points or less) was the
dependent variable.
Results: GNRI at admission was a significant positive
independent variable in the multiple regression
analysis. GNRI at admission and degree of GNRI
improvement were both significant independent
variables in the multiple logistic regression analysis,
with odds ratios of 1.084 and 1.090, respectively.
Conclusion: Improvements in motor FIM are greater
when GNRI at admission and the degree of GNRI
improvement are larger.
Key words: Geriatric Nutritional Risk Index, FIM gain, stroke, multiple regression analysis, multiple logistic regression analysis
