Poor nutritional status is prevalent in peritonealdialysis (PD) patients and is related to morbidity and mortality.Therefore, the aim of the present study was to assess the dietaryintake and its related factors in PD patients in Tehran, Iran.Methods. All eligible PD patients in Tehran peritoneal dialysiscenters were included in this cross-sectional study. Dietary intakeof PD patients was determined using a 3-day dietary recall. Also,a 4 mL blood sample was obtained from each patient to measureserum biochemical parameters.Results. Intake of energy, protein, and fiber were lower thanrecommended values in 81%, 92%, and 100% of PD patients;respectively. The prevalence of inadequate energy intake in PDpatients with dialysis vintage ≤ 5 years was significantly higheras compared to those with dialysis vintage > 5 years (P < .05). Asignificant association was observed between inadequate energyintake and inadequate vitamin B3 intake (P < .05). There was amarginally (not) significant association between inadequate energyintake and inadequate vitamin B1 intake (P = 0.06). Intake of thevitamins B1, B2, B3, B6, folic acid, B12, E, C, and of the minerals,calcium, and zinc from both the diet and supplements were lowerthan recommended values in 15%, 38%, 23%, 39%, 52%, 32%, 47%,29%, 54%, and 50.5% of PD patients, respectively.Conclusion.
