Insights

Children with overweight or obesity show increased carotid artery intima-media thickness (IMT), a marker of early atherosclerosis. This meta-analysis confirms significantly higher IMT in obese children compared to normal-weight peers using ultrasound techniques.

Area of Science:

  • Pediatric Cardiology
  • Vascular Ultrasound
  • Public Health

Background:

  • Carotid artery intima-media thickness (IMT) serves as a non-invasive ultrasound indicator of early atherosclerosis.
  • Childhood obesity is a growing public health concern with potential long-term cardiovascular implications.

Purpose of the Study:

  • To systematically review and meta-analyze published data on IMT differences in children with overweight or obesity compared to normal-weight controls.
  • To assess the impact of overweight and obesity on IMT in pediatric populations.

Main Methods:

  • Systematic review and meta-analysis adhering to PRISMA guidelines.
  • Inclusion of cohort studies with normal weight controls and IMT measurements via B-mode or radiofrequency (RF) echo-tracking techniques.
  • Utilized World Health Organization growth standard definitions for childhood obesity and searched major scientific databases from inception to February 2024.

Main Results:

  • Analysis of 15 B-mode and 2 RF echo-tracking studies revealed significantly increased IMT in children with overweight/obesity.
  • Mean IMT was higher by 0.041 mm (95% CI: 0.031–0.052) using B-mode and 0.045 mm (95% CI: 0.029–0.062) using RF techniques.

Conclusions:

  • This meta-analysis demonstrates a significant increase in carotid artery intima-media thickness in children living with obesity compared to normal-weight children.
  • Findings underscore the utility of IMT as a biomarker for subclinical atherosclerosis in pediatric obesity, irrespective of measurement technique.
