Abstract
Introduction. Chronic kidney disease (CKD) involves multiple factors that contribute to an altered nutritional status. Among these, protein-energy malnutrition (PEM) is a major concern, as it negatively affects patient prognosis. Its prevalence varies depending on the diagnostic method used. The aim of this study was to assess the prevalence of malnutrition in patients with chronic kidney disease. Materials and Methods. This descriptive, cross-sectional, non-interventional study evaluated the nutritional status of adult patients with end-stage renal disease (ESRD), aged 18 to 65 years, of both sexes. The assessment included dietary surveys, clinical examinations, and biochemical tests. The study was conducted in the hemodialysis unit of the Nephrology, Hemodialysis, and Transplantation Department at Ibn Sina University Hospital in Annaba, between October 2016 and January 2017. All participants completed a standardized questionnaire, underwent clinical and anthropometric assessments, and provided blood samples for biochemical analysis. Nutritional intake was also evaluated. Malnutrition was diagnosed using two tools: the Quetelet index (Body Mass Index) and the Subjective Global Assessment (SGA). Results.
A total of 74 patients were included. The overall prevalence of malnutrition was 16.2% according to the Quetelet index and 28.4% based on the SGA score. Mean protein and energy intake levels were suboptimal, averaging 23.64 ± 28.77 kcal/kg/day and 0.87 ± 0.30 g protein/kg/day (based on dry weight), respectively. Conclusion. Patients with chronic kidney failure are at high risk of malnutrition. This highlights the need for systematic nutritional screening, individualized dietary interventions, and regular psychological support to optimize adherence to therapeutic diets and improve patient outcomes.
