Is Body Protein Index Based On Bioelectrical Impedance Analysis A Reliable Marker For Nutritional Status Assessment?

Dr. Nitoi Luciana Carmen, Dr. Maria Cristina Vladeanu

Abstract :

Bioelectrical impedance analysis (BIA) is a method extensively used in studies assessing body composition, as a non–invasive method for generating information through portable, easy to use and relatively inexpensive equipment that estimates the body components. Signs of protein–energy malnutrition are common in maintenance hemodialyis (HD) patients and are associated with increased morbidity and mortality. To evaluate the nutritional status and relationship between various parameters used for assessing malnutrition, we performed a cross–sectional study in 69 HD patients treated with thrice weekly sessions for at least three months. The aim of our study was to assess the prevalence and degree of malnutrition in a population of HD patients, using mSGA (modified Subjective Global assessment) and BIA, and analyze the usefulness of a new nutritional marker Body Protein Index (BPI) based on bioimpedance analysis. The majority of our study patients was found to suffer of a variable degree of malnutrition. Strong correlations were found between BPI and anthropometric measurements, laboratory data and BIA nutritional markers. In conclusion, BPI could evaluate whole body somatic protein stores, and is a potentially useful new marker assessing nutritional status in HD patients.
