Abstract

Background: This study aimed to assess the prevalence of malnutrition according to Subjective Global Assessment (SGA), Mini Nutritional Assessment-Full Form (MNA-FF), and different combinations of the Global Leadership Initiative on Malnutrition (GLIM) criteria in older adults who are institutionalized, and the impact of malnutrition on 5-year mortality.

Methods: Nutrition status was assessed by the SGA, MNA-FF, and 15 GLIM criteria combinations. The Katz scale was used to assess the level of dependence. The SGA was considered the reference method, and the agreement (Kappa test), sensitivity, and specificity values were calculated for each GLIM criteria combination. The variables associated with 5-year mortality were assessed using multivariate logistic regression models.

Results: One hundred eleven participants (mean age: 81y; interquartile range: 76.0-87.0; 90.9% women) were included; the prevalence of malnutrition according to the SGA and MNA-FF were 49.5% (n = 55) and 8.1% (n = 9), respectively. The prevalence of malnutrition varied from 1.8% to 36.0% considering GLIM combinations. Eight GLIM criteria combinations had a fair agreement with SGA (κ: 0.21-0.40), and two had sensitivity >80%. Regarding mortality, 43 participants (38.7%) died within 5 years. Malnutrition according to the SGA (odds ratio [OR]: 2.82; 95% confidence interval [CI]: 1.06-7.46) and the Katz scale score (OR: 4.64; 95% CI:1.84-11.70) were independent predictors of mortality.

Conclusion: The prevalence of malnutrition varied according to the assessment tools. Malnutrition diagnosed by the SGA, but not by the GLIM criteria or MNA-FF, was associated with 5-year mortality in older adults who were institutionalized.
