Abstract: 〗［Abstract］ Objective〖HTSS〗〓To investigate the compliance rate of macronutrients of dietary intake, the incidence of protein energy wasting(PEW) and food consumption data in patients with chronic kidney disease(CKD).
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓A total of 354 CKD patients hospitalized in Lanzhou University Second Hospital were enrolled in this study. The food consumption data were collected by weighing method combined with 3 consecutive 24hour recalls, and the nutrients intake was calculated by China Food Composition Table. Nutritionrelated indexes were analyzed, which included energy, protein, lipid, carbohydrate, albumin，hemoglobin, body mass index（BMI）, incidence of PEW, and consumption data of nine categories food, such as beans, white meat, red meat, eggs, dairy products, staple foods, oils, fruits and vegetables.
〖HTH〗〖WTHZ〗Results〖HTSS〗〓In 354 patients with the stages CKD1-5, the number of patients reached the energy recommendation was 88 and compliance rate was 24.8%. The number of patients reached the protein recommendation was 32 and compliance rate was 9.0%. The number of patients reached the lipid recommendation was 51 and compliance rate was 14.4%. The number of patients reached the carbohydrate recommendation was 88 and compliance rate was 24.8%. The number of patients reached the albumin recommendation was 173 and compliance rate was 48.9%. The number of patients reached the albumin recommendation was 117 and compliance rate was 33.0%. The number of patients reached the BMI recommendation was 165 and compliance rate was 46.6%. In total, these indexes mentioned above were gradually decreased but the incidence of PEW was increased with the progress of CKD. The intake of nine categories food, like beans, white meat, red meat, eggs, dairy products, staple foods, oils, fruits and vegetables was inclined with the progression of the disease. 〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓The compliance rate of dietary intake of three macronutrients, such as protein, lipid, carbohydrate, is low and the incidence of PEW is high in patients with CKD. The diets among CKD patients are mainly staple foods and are lack of biological protein, vegetables and fruits in these patients. Consequently，all patients with CKD need to implement target nutrition management by practicing individual dietary guidance and goal nutrition therapy.
