Correlation between skinfold thickness and bioelectrical impedance analysis for the evaluation of body composition in patients on dialysis.

Introduction: Patients on dialysis have important changes in body composition.

Objectives: To determine the correlation between skinfold thickness (SKF) and bioimpedance analysis (BIA) for estimating fat mass (FM) and lean body mass (LBM) in patients undergoing hemodialysis (HD) and peritoneal dialysis (PD).

Methods: Cross-sectional study.
