Factors Associated With Anthropometric Indicators of Nutritional Status in Children With Chronic Kidney Disease Undergoing Peritoneal Dialysis, Hemodialysis, and After Kidney Transplant

摘要

ObjectiveThe objective of the study was to demonstrate that there are differences in the factors associated with anthropometric indicators of nutritional status, with particular emphasis on arm indicators, in children with end-stage kidney disease undergoing peritoneal dialysis (PD), hemodialysis (HD), and after kidney transplant (KT). MethodsAn analytical cross-sectional study of consecutive cases included 130 children and adolescents with end-stage kidney disease undergoing substitutive treatment: 49 patients who underwent KT, 33 undergoing PD, and 47 undergoing HD. Socioeconomic data were obtained from all the 3 groups; anthropometric indicators of nutritional status were calculated. Student'st-test and analysis of variance were used for parametric variables. Chi-square test, Mann-WhitneyUtest, Kruskal-Wallis test, and odds ratio (OR) were used for nonparametric variables. ResultsThe number of parents living as couples was higher for patients who underwent KT (OR?=?3.5 [95% confidence interval {CI} 1.34-9.0]) and undergoing PD (OR?=?3.0 [95% CI 1.06-8.8]) than those undergoing HD. The number of mothers who worked outside the home was higher for patients who underwent KT and undergoing PD than the mothers of patients undergoing HD (OR?=?13.7 [95% CI: 4.56-41.05]; OR?=?15.4 [CI 95% 4.8-49], respectively). Family income was higher for patients who underwent KT and undergoing PD (P?=?.019,P?=?.093, respectively). More than 40% of patients in all the 3 groups had growth impairment. Body mass index, mid-upper arm circumference, tricipital and subscapular skinfolds, total arm area, and arm fat area were affected in HD and PD groups (9 to 40%), while of the patients who underwent KT, 36.7% were overweight or obese. More than 50% of patients who underwent KT and undergoing HD and PD had involvement in the arm muscular area. ConclusionsSocioeconomic conditions are more influential for children in the HD program. The nutritional status of children after KT improves; however, not all anthropometric indicators are fully recovered. Children after KT are up to 9 times more likely to be overweight or obese.
