ObjectiveThis 1-y cohort study examined whether Council of Nutrition Appetite Questionnaire (CNAQ) scores predicted mortality in 316 elderly Japanese residents of five nursing homes (60 men, 256 women; mean age: 84.9 ± 8.3 y).MethodsThe baseline survey included participant characteristics (e.g., age, sex, height, weight, and medical history), and Barthel Index (BI), Clinical Dementia Rating (CDR), Mini Nutritional Assessment-Short Form (MNA®-SF), CNAQ, Simplified Nutritional Appetite Questionnaire (SNAQ; simplified CNAQ), and SNAQ for the Japanese elderly (SNAQ-JE) scores.ResultsFollowing the baseline survey, mortality data were collected for 1 y; during this time, 62 participants (19.6%) died. The deceased group's CNAQ scores (25.1 ± 4.8) were significantly lower than those of the survival group (28 ± 3.6; P < 0.001). After adjusting for age, sex, medical history, BI, CDR, and MNA®-SF scores in Cox proportional regression, CNAQ (hazard ratio [HR], 0.91; 95% confidence interval [CI], 0.85-0.97; P = 0.004), SNAQ (HR, 0.84; 95% CI, 0.75-0.93; P = 0.001), and SNAQ-JE (HR, 0.84; 95% CI, 0.76-0.92; P < 0.001) scores were related to mortality.ConclusionsThis study showed that CNAQ scores were inversely associated with 1-y mortality. Furthermore, appetite assessment using the CNAQ predicted the death of Japanese nursing home residents. Similarly, the SNAQ and SNAQ-JE scores were inversely associated with 1-y mortality.Copyright © 2019 Elsevier Ltd. All rights reserved.
