Obesity among adolescents is a growing global concern associated with significant cardiovascular health risks, including hypertension, diabetes, and atherosclerosis. Carotid Intima-Media Thickness (CIMT), a non-invasive marker of early atherosclerosis, has emerged as a critical tool for assessing vascular health in pediatric populations. Elevated CIMT in obese adolescents reflects early structural changes in arterial walls, indicating heightened cardiovascular risk in later life. Early detection through CIMT measurement allows for targeted interventions to mitigate long-term cardiovascular complications.
