Objective: This study aimed to describe the nutritional status of geriatric home residents according to their place of dwelling and to identify institutional factors associated with higher rates of undernutrition.
Method:
Results:The estimated prevalence of undernutrition was 19.1 (95% CI: 14.0-24.2) with a higher rate in long-term care (48.0 % (95% CI: 15.9-80.2) than in nursing homes (14.5 % (95% CI: 10.6-18.4), p< .0001). In univariate analyses the risk of undernutrition was higher in long-term care (P < .0001), in settings with better weighing equipment (P < .0001), higher * Manuscript 2 staff ratio (P = .0001), higher rate of subjects needing help for eating (P < .0001) and was lower in settings with a higher rate of training in nutrition screening (P = .0001) and management (P < .0001). In nursing homes, each item of the MNA-Short Form was independently predictive of undernutrition. In multivariate analyses in nursing homes only, better weighing equipment (OR adj 2.34, 95% CI 1.39-4.12, P = .0017) and higher staff ratio (OR adj 1.03, 95% CI 1.00-1.05, P = .0230) were associated with higher rates of undernutrition.Conclusions: Undernutrition in institutions was linked to the resident health problems with little evidence in favor of the influence of institutional policies
