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
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
