We investigated sarcopenia and its traits in children and adolescents with chronic kidney disease.
MethodsPhysical function was assessed using handgrip strength (HGS) and the 60-second sit-to-stand (STS-60).Body composition was assessed by bioelectrical impedance and anthropometry through mid-upper arm circumference (MUAC). Probable sarcopenia was considered as low HGS, whereas sarcopenia by adding low MUAC.
ResultsTwenty-two patients were evaluated (11 ± 4 years and 59% boys). Sarcopenia prevalence was 50%. Low physical function by HGS and STS-60 was 59% and 100%, respectively, while low MUAC in 77%. HGS was positively associated with all body composition variables in the non-dialysis and peritoneal dialysis groups; on the other hand, the STS-60 was not signi cantly associated with any of the body composition variables.
ConclusionAmong pediatric patients with CKD, the prevalence of sarcopenia was high. Therefore, strategic interventions to body composition will likely confer positive bene ts on HGS, but not on STS-60.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
