MENDIAS BENITEZ, Cristina et al. Electrical bioimpedance: Different methods of assessment of the nutritional state in a peripheral haemodialysis centre. Rev Soc Esp Enferm Nefrol [online]. 2008, vol.11, n.3, pp.173-177. ISSN 1139-1375.

Introduction. Thanks to bioimpedance it is possible to evaluate the state of hydration of the patient independently of body weight. It also identifies the lean protein reserves and fat reserves in the patient. Objectives. 1. Description of the nutritional state of the stable population in a peripheral centre measured by: bioimpedance, anthropometrics, subjective global assessment and analytical data. 2. Comparison and analysis of the different nutritional evaluation methods. Methodology. Analytical, prospective, comparative study of the different ways of evaluating the nutritional state of the 52 stable patients in our centre. We studied the match between variables and we compared significant parameters of each nutritional evaluation method: Results. By subjective global assessment we found a high risk of malnutrition in 63.46% of patients, bioimpedance indicated malnutrition in 59.61%. Serum albumin showed 56.8% of patients in an adequate nutritional state while 51.21% are in this state if serum transferrin is considered. There are many methods for evaluating the nutritional state of our patients. A correlation is observed between the subjective global assessment and the nutritional analysis.
