Hemodialysis (HD) and peritoneal dialysis (PD) are the most commonly used renal replacement therapy. The nutritional status of chronic kidney disease (CKD) patients can be influenced by the dialysis modality used. Objective: To compare the nutritional status of patients in HD and PD, through anthropometric and biochemical evaluation. This is a cross-sectional study carried out in the nephrology sector of the University Hospital of the Federal University of Juiz de Fora. The study consisted of 29 patients in PD and 36 in HD, totaling 65 patients. The data collected were: dry body weight, stature, body mass index (BMI), arm muscle area (BMA), arm muscle circumference (BMC), triceps skin fold and arm circumference. In addition, the biochemical tests: potassium, phosphorus, urea and albumin. It is possible to observe a higher prevalence of female sex in the PD modality in relation to HD (75% X 44.4%, p = 0.01). There was a difference in dialysis times between groups (SD: 41.86 ± 33.2 months X HD: 22.36 ± 5.4 months, p = 0.001). Regarding BMC classification, 48.3% of patients in PD and 22.2% in HD were classified as eutrophic (p = 0.001). As for BMA, 72.5% of patients in PD and 36.1% of patients in HD were classified as eutrophic (p = 0.001). In relation to the biochemical tests, only potassium had a significant difference between the groups (SD: 4.9 ± 0.73 mEq / L and HD: 5.64 ± 0.78 mEq / L, p = 0.01). In the present study, patients in PD present better classification in relation to BMC and BMA, in addition to better control of serum potassium, compared to patients in HD.
