Prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) and its association with arterial stiffness in adolescents: Results from the EVA4YOU study.

Abstract

AimTo determine the prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) among Western Austrian adolescents and its association with arterial stiffness as a marker of early vascular ageing.MethodsIn the cross-sectional Early Vascular Ageing in the YOUth study, liver fat content was assessed by controlled attenuation parameter (CAP) using signals acquired by FibroScan (Echosense, Paris, France) in 14- to 19-year-old Austrian adolescents. Arterial stiffness was determined by carotid-femoral pulse wave velocity (cfPWV) and cardiovascular risk factors by a face-to-face interview, physical examination, and fasting blood analyses. Linear regression models and one-way analysis of variance were performed to analyze the association between liver fat content, MASLD and cfPWV.ResultsA total of 1292 study participants (65.2% female) aged 17.2 ± 1.3 years were included. MASLD was detected in 62 (4.8%) adolescents. CAP value showed a significant association with cfPWV in the unadjusted model (p ConclusionIn our adolescent cohort, liver fat content and MASLD were not found to be independent predictors for early vascular ageing. Nevertheless, the determination of liver fat content can be a useful tool to identify adolescents at high risk for cardiovascular disease and metabolic syndrome.
