Researchers evaluated the value of the controlled attenuation parameter (CAP), as determined by a liver elastography technique, in prognosticating varying degrees of liver steatosis in children with obesity.

• Retrospective analysis of children with obesity attending the pediatric obesity clinic at the Affiliated Hospital of Hangzhou Normal University from July 2020 to May 2021.

• In accordance with the degree of liver steatosis obtained by magnetic resonance imaging-proton density fat fraction (MRI-PDFF), division of the 71 individuals was performed.

• In Logistic regression analysis performed between CAP, ALT, AST, and moderate to severe hepatic steatosis in children with obesity, CAP was identified as a factor linked to moderate to severe hepatic steatosis in children with obesity.

• Based on findings, CAP is suggested as diagnostically valuable for hepatic steatosis in children with obesity, and there is greater diagnostic value in the use of CAP for children with moderate to severe hepatic steatosis.
