Association Between Body Mass Index and Body Fat in Chronic Kidney Disease Stages 3 to 5, Hemodialysis, and Peritoneal Dialysis Patients

Body composition did not differ in patients with CKD stages 3 to 5, and between dialysis modalities. Although BMI was strongly and significantly correlated with body FM in CKD patients at stages 3 to 5, lean body mass was not. These findings suggest that BMI is a reliable indicator of body FM in this CKD population.
