Abstract:

Ｏｂｊｅｃｔｉｖｅ：To  explore whether Boaz formula can truly reflect phosphorus intake in CKD patients in China, and  whether Maroni formula can accurately predict protein intake in patients with CKD 3～5 patients.
Ｍｅｔｈｏｄｏｌｏｇｙ：In  department of renal medicine,the first affiliated Hospital of China Medical University,from March 2016 to June 2017,the CKDEPI formula was used to calculate the renal function of patients with GFR,and 110 inpatients with CKD 3～5D stage were selected. Renal physicians selected according to the criteria of inclusion and exclusion of patients were introduced to nutritionists for nutrition education,dietary survey (3 days and 24 hours diet weighing method),to compare the actual intake of protein and phosphorus in patients and the recommended and estimated intake relationship.
Ｒｅｓｕｌｔｓ：The actual intake of protein in patients with CKD 3～5 was in accordance with the recommended intake,but there was a significant difference between the actual intake of protein and the estimated intake of maroni (P<005). The actual intake of phosphorus in CKD 3～4 and CKD 5D patients was lower than the recommended amount in the standard range,and there was no significant difference between each period and the estimated intake of Boaz (P>005).
Ｃｏｎｃｌｕｓｉｏｎ：Most CKD patients can reasonably control their diet according to the recommended amount of guidelines; Maroni formula may not be suitable for evaluating protein intake of CKD patients in China,but Boaz formula is suitable for estimating phosphorus intake.

Key words: protein intake, phosphorus intake, Maroni formula, Boaz formula
