Body composition changes and its association with dyslipidemia in patients receiving hemodialysis

Problem considered: The study aimed to assess the body composition changes after dialysis in chronic kidney disease (CKD) patients undergoing hemodialysis and to determine the strengths of relationships between various body composition parameters and blood lipid levels in these patients. Methods: The cross-sectional study was conducted during May-September 2019 involving 97 patients (58 males and 39 females, age: 40-70 years) of CKD undergoing maintenance hemodialysis. The multifrequency bioelectrical impedance analyzer was used to measure various body composition parameters like body fat percent, lean mass percent, body mass index, body fat mass index, fat-free mass index, total body water percent, extracellular water percent, intracellular water percent, nutrition index, prediction marker, basal metabolic rate, and estimated average energy requirement. Blood lipid levels were collected from the patients' clinical records. Results: All the body composition parameters except nutrition index and prediction marker differed significantly before and after dialysis. Various body composition parameters were significantly correlated with one or more lipid levels before and after dialysis. Conclusion: The body composition parameters change significantly after hemodialysis among CKD patients. Our findings suggest that body composition parameters, whether measured before or after dialysis could be useful in assessing dyslipidemia in patients receiving hemodialysis.
