CAPOTE PEREIRA, Lázaro L.; MORA GONZALEZ, Salvador  and  ARTIMES HERNANDEZ, Yanet. Impact of malnutrition on mortality in chronic hemodialysis patients. Rev Cub Med Mil [online]. 2005, vol.34, n.3, pp. 0-0. ISSN 1561-3046.

A case -control study design was made to compare a group of 20 dead patients (cases) with 27 living patients (controls). Their nutritional state was determined and correlated to death frequency. The information was shown in contingency tables to estimate odds ratio (OR) and the multivariate logistic regression was used to calculate the association strength between the series of studied variables. The cases presented mean values of urea, cholesterol and creatinine lower than the controls. Of the total of 20 cases, 19 showed protein-energy malnutrition for an OR of 13 and a confidence interval of 95 %, 11.4 (p = 0.005). In the analysis of multivariate logistic regression the protein-energy malnutrition was related to mortality with a coefficient of 2.49, an OR of 12.07 and a confidence interval of 95.%, 105.15 (p 0.05). The protein-energy malnutrition is a strong predictor of mortality and the global subjective nutritional assessment is an efficient method to show different degrees of malnourishment and to predict mortality in patients with end-stage chronic renal failure on hemodialysis.
