STUDY OF THE NUTRITIVE STATUS OF CHRONIC OBSTRUCTIVE PULMONARY DISEASE PATIENTS BY USING THE METHODS OF ANTHROPOMETRY AND BIOIMPEDANCEMETRY
Malnutrition relates to clear and frequent manifestations of chronic obstructive pulmonary disease (COLD) which affects a frequency of exacerbations, indices of external respiration and quality of patients’ life. The purpose of the study is to evaluate a condition of nutritive status of COLD patients by using the methods of anthropometry and bioimpedancemetry from a comparative standpoint. 60 patients with I, II and III stages of COLD have been examined. In accordance with the findings obtained, a body mass index (BMI) is reduced at II and III stage of COLD in comparison with a test group. Loss in muscular component or lean body mass (LBM) occurs at I stage of COLD, the most significant reduction in LBM is found at III stage of disease. By comparison of the two diagnostic methods any reliable differences in the indices of BMI and LBM in the general group of COLD patients and at various stages of disease are not found. When separating the examined patients into groups with normal, reduced and increased body mass there are established significant differences in the indices of LBM in the group of patients with BMI >25 kg/m2. The said group has lower indices of LBM by bioimpedancemetry method in comparison with anthropometry method. Correspondingly, the method of bioelectrical impedance may be recommended for more exact evaluation and early disease detection of protein-energy deficiency in COLD patients with BMI > 25kg/m2.
