To improve risk stratification, the European Association for the Study of Obesity (EASO) proposes to extend the diagnosis of obesity to include individuals with a BMI of 25\u201330 kg\/m\u00b2, a waist-to-height ratio (WtHR) \u22650.5, and any obesity-related complication.<\/jats:p><\/jats:sec><jats:sec><jats:title>Objective<\/jats:title><jats:p>To examine whether this new definition of obesity can better identify the presence of subclinical atheromatosis disease (SAD) in terms of arterial plaque burden compared to the classical BMI-based definition.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>A cross-sectional including 8,330 participants from the ILERVAS project (ClinicalTrials.gov Identifier: NCT03228459), aged 45\u201370 years with low-to-moderate CV risk and no previous CV disease, was included. Obesity was classified using traditional (BMI \u2265 30 kg\/m\u00b2) and new definitions. Atherosclerosis was assessed through Doppler ultrasound of carotid and femoral arteries. Logistic regression models adjusted for cardiovascular risk factors were used to evaluate associations between obesity definitions and SAD.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The new definition increased obesity prevalence from 37.2% to 71.7%. It also revealed higher detection of atheromatous plaques (72.9% vs. 68.6%, <jats:italic>p<\/jats:italic> &amp;lt; 0.001) and affected more vascular territories. Multivariable analysis showed the new definition independently predicted overall plaque presence (OR 1.54, 95% CI 1.22\u20131.94, <jats:italic>p<\/jats:italic> &amp;lt; 0.001) and femoral atherosclerosis (OR 1.36, 95% CI 1.10\u20131.68, <jats:italic>p<\/jats:italic> = 0.004).
