Abstract: ObjectiveTo investigate the nutritional status of children with chronic kidney disease (CKD） and the influencing factors of malnutrition.MethodsAccording to the US National Kidney Foundation practice guidelines for CKD in 2002, children diagnosed with CKD in Yongxing Hospital, Zhoukou were recruited from September 2012 to October 2015 to participate in a nutritional survey. Their body height, body mass and other parameters were mearured. The nutritional status of CKD children was evaluated using the WHO generic Z value standard. Questionnaire survey of the knowledge related nutrition was conducted among parents of the children. The incidence of malnutrition in children with CKD and factors influencing the malnutrition were analyzed.ResultsA total of 1 500 children with CKD were enrolled in the study. Their age ranged from 3 to 14 years and the average age was (8.7 ± 3.5) years. Of all the children with CKD, 810 were male and 690 female, with a male to female ratio of 1.17∶1. Average duration of CKD was (2.8 ± 1.3) years, and there were 375 cases in Stage 1 CKD, 420 in Stage 2 CKD, 300 in Stage 3 CKD, and 405 in Stage 4 CKD. There were 878 CKD cases with malnutrition and the incidence of malnutrition was 58.5%. Of them, 230 cases were growth retardation, 182 were low body mass, and 466 were emaciated. Multivariate logistic regression analysis showed that CKD children with longer duration(OR=1.773) and higher CKD stages (OR=1.598）were more likely to have malnutrition. The children with CKD, whose parents understood malnutrition knowledge (OR=0.598), received nutrition knowledge guidance (OR=0.472), knew the concept of nutrients (OR=0.603), had their children nutritional status checked (OR=0.617), and concerned about the children's diet (OR=0.392), were less likely to suffer from malnutrition.ConclusionThe incidence of malnutrition in children with CKD was high. The higher the CKD stage and the longer the course of disease, the higher the risk of malnutrition in children. Parents knowing more about the knowledge of malnutrition can help to reduce the occurrence of malnutrition in children.
