Objectives. Current adherence to dietary recommendations for chronic kidney disease was evaluated in kidney transplant patients in the maintenance phase.
Methods. A total of 268 maintenance phase kidney transplant patients were included in the study. Estimated daily intakes of oral protein and salt were calculated from 24-h urinary excretion of nitrogen and sodium, respectively. Dietary recommendations for chronic kidney disease, as issued in 2014 by the Japanese Society of Nephrology, were used as the basis for assessing diet.
Results. The study included 114 female patients and 154 male patients. The mean age, posttransplantation years, body mass index, estimated glomerular filtration rate, and 24-h urinary excretion of protein were 56.3 years, 11.2 years, 22.0 kg/m(2), 42.6 mL/min/1.73 m(2), and 321 mg/d, respectively. Estimated daily protein and salt intakes were 0.98 +/- 0.26 g/kg/d and 9.3 +/- 3.9 g/d. Only 47 patients (17.5%) in the case of salt intake and 105 patients (39.2%) in the case of protein intake were within reference values. The 24-h urinary protein excretion of the daily salt intake-adherent group (<6 g) was significantly less than that of the nonadherent group (>= 6 g) (P = .021).
Conclusions. The adherence rate to dietary recommendations for chronic kidney disease in kidney transplant patients was low. The 24-h urinary protein excretion of the daily salt intake-adherent group was significantly less than that of the nonadherent group. Dietary therapy for these patients may have the potential to improve kidney graft function and survival.
