Abstract
BACKGROUND: Diabetes and older age are associated with an increased risk of malnutrition and mortality. Recently, the Global Leadership Initiative on Malnutrition (GLIM) provided a 2-step approach for the malnutrition diagnosis. In this study, we aimed to determine whether GLIM nutrition status at admission was associated with long-term survival in elderly patients with type 2 diabetes mellitus (T2DM). Additionally, we aimed to identify which GLIM criteria were more able to become prognostic indicators of early or late death. METHODS: Our study included a convenience sample of 159 patients with T2DM older than 65 years and admitted to the internal medicine wards of different Spanish hospitals: the VIDA-survival cohort. Nutrition status was retrospectively assessed with the new GLIM criteria. The main outcome was long-term mortality in the cohort during an 8-year follow-up. Bivariate tables summarized the variables of interest. Kaplan-Meier survival curves and adjusted Cox regressions were also performed. RESULTS: According to the GLIM criteria, we observed that the 35.8% and 16.3% of the VIDA-survival cohort were categorized as having moderate and severe malnutrition, respectively. Severe malnutrition was associated with increased mortality (hazard ratio [HR] = 2.09; 95% CI, 1.29-3.38), compared with nonmalnourished participants. Moderate malnutrition had a neutral effect on all-cause mortality (HR = 1.30; 95% CI, 0.88-1.92). Low plasma albumin levels, a surrogate marker of inflammation, were strongly associated with early mortality. CONCLUSION: Our study provides evidence that severe malnutrition according to GLIM criteria is associated with increased long-term all-cause mortality among elderly individuals with T2DM.
