Malnutrition is a common problem in peritoneal dialysis patients, which is closely correlated with mortality. Assessing the dietary protein intake of PD patients regularly and directing them to take proper diet accordingly is important for preventing malnutrition, improving patients’quality of life, and decreasing complications and mortality. In this review, we summarized the dietary protein intake assessments, including direct and indirect methods, analyzed the advantage and disadvantage of each method, and pointed out the research focus in future.
