Abstract:
The European Society of Clinical Nutrition and Metabolism (ESPEN) has developed a consensus definition of malnutrition. This study aimed to determine the prevalence of malnutrition according to the ESPEN definition in otherwise healthy community-dwelling older women and to explore its value for predicting long-term mortality in this population.This prospective population-based cohort study included 181 women (age ≥75 years) from a subsample of the EPIDémiologie de l'OStéoporose (EPIDOS) study participants from Toulouse. Inclusion criteria were the availability of the data on variables required to apply the ESPEN definition and survival after 7 years of follow-up. Primary outcome was mortality at 12-year follow-up; main covariates were malnutrition assessment according to the ESPEN consensus and its components (unintentional weight loss, BMI, and FFMI). Body composition was assessed by dual-energy X-ray absorptiometry at baseline and at 7-year follow-up. Kaplan-Meier survival curves and adjusted Cox regressions were performed. Analysis was adjusted for age, hypertension, diabetes mellitus, and coronary heart disease as potential confounders.Complete data were available for 179 of the 181 women in the EPIDOS-Toulouse cohort (83.1 ± 2.2 years) and 13 (7.3%) fulfilled the ESPEN definition for malnutrition at 7-year follow-up. Malnutrition was associated with increased risk of mortality (adjusted HR = 4.4 [95%CI: 1.7–11.3]). Among the ESPEN components, only BMI was associated with increased mortality (adjusted HR=0.6 [95%CI: 0.4–0.9]).Although malnutrition prevalence according to the ESPEN definition was relatively low (7.3%) in this sample of otherwise healthy community-dwelling older French women, malnutrition was associated with 4.4-fold higher mortality risk at 12-year follow-up.
