dc.description.abstractIntroduction: Subclinical atherosclerosis is increasingly recognized in younger populations, often progressing silently until the onset of overt cardiovascular events. Carotid intima-media thickness (CIMT) is a validated, non-invasive biomarker of early vascular alterations. Although the Mediterranean diet (MD) is well established as cardioprotective, its relationship with CIMT in young adults remains insufficiently studied. Objective: To assess sex-specific adherence to the Mediterranean diet and its association with carotid intima-media thickness in a cohort of university students. Methods: A cross-sectional study was performed involving 60 university students (50% male, aged 17–25 years), selected through stratified probabilistic sampling. Data were collected on sociodemographic characteristics, vascular risk factors, MD adherence via the PREDIMED questionnaire, and CIMT measured using a high-resolution carotid Doppler ultrasound. Statistical analyses included chi-square tests and descriptive statistics, with significance set at ρ ≤ 0.05. Results: A notable 95% of participants showed low adherence to the Mediterranean diet. Significant sex differences in dietary patterns were identified: males consumed more red meat (ρ = 0.023), while females reported higher fish intake (ρ = 0.037). Despite behavioral risk factors, all CIMT values remained within normal ranges (≤0.9 mm). No significant association was found between MD adherence and CIMT (ρ = 0.554). Conclusion: This exploratory study reveals a high prevalence of modifiable cardiovascular risk factors, including poor dietary adherence, among young adults, despite the absence of detectable vascular structural changes. Although no significant association was found, the findings reflect the dietary and behavioral profiles of a young, low-risk population.
