Objective:
To examine the relationship between decreased appetite and the cognitive function in elderly diabetic patients.
Methods:
The study subjects were outpatients with diabetes who were 60 years of age or older, and who were managed at Ise Red Cross Hospital. The cognitive function was assessed using a self-administered Dementia Checklist. The Japanese version of the Simplified Nutritional Appetite Questionnaire (SNAQ) was used to measure decreased appetite. A logistic regression analysis, in which the dependent variable was cognitive decline and the explanatory variables were appetite loss and adjustment variables, was used to calculate the odds ratio for cognitive decline according to the presence of appetite loss.
Results:
Four hundred eighty patients were included in the analysis. Seventeen percent of the patients had decreased appetite and 21% had a decreased cognitive function. The unadjusted and adjusted odds ratios of cognitive decline for those with decreased appetite were 2.78 (95% confidence interval (CI), 1.66-4.65; P<0.001) and 2.26 (95% CI, 1.16-4.37; P=0.015), respectively, based on the absence of decreased appetite.
Conclusion:
Decreased appetite in elderly patients with diabetes was associated with a decreased cognitive function.
