Hyperphosphatemia in chronic kidney disease (CKD) is associated with vascular calcification, cardiovascular morbidity and mortality. The aim of this study was to estimate the daily dietary phosphorus intake compared with recommendations in CKD patients and to evaluate the reproducibility of the 24-h urinary phosphorus excretion. Twenty CKD patients stage 3-4 from the outpatient clinic, collected 24-h urine and kept dietary records for 3 consecutive days. The mean daily phosphorus intake was 1367±499, 1642±815 and 1426±706 mg/day, respectively (P=0.57). The mean urinary phosphorus excretion was 914±465, 954±414 and 994±479 mg/day, respectively (P=0.21). In this population of CKD patients stage 3-4 the daily phosphorus intake was above the recommended. Twenty-four-hour urinary phosphorus excretion was reproducible and the data indicate that a single 24-h urine collection is sufficient to estimate the individual phosphorus excretion.European Journal of Clinical Nutrition advance online publication, 14 December 2016; doi:10.1038/ejcn.2016.247.
