Abstract
We aim to evaluate the prevalence of steatotic liver disease (SLD) in United States (US) adolescents and explore whether metabolic dysfunction-associated steatotic liver disease (MASLD) can identify individuals with clinically significant fibrosis (CSF) in this study. The prevalence of SLD and its categories, including MASLD, metabolic dysfunction and alcohol associated liver disease (MetALD), alcohol related liver disease (ALD) and other SLD were determined. Weighted multivariable logistic regression analysis was conducted to evaluate the association between MASLD and CSF in adolescents with SLD. Among the total 1,446 US adolescents, SLD was present in 291 (20.1%) of individuals, including 260 (17.9%) for MASLD, 9 (0.6%) for MetALD and 5 (0.3%) for ALD. Only 58 (4%) had CSF. Patients with SLD showed a higher prevalence of CSF (9.6% vs. 2.6%, p < 0.001). Among patients with SLD, 89.3% met the MASLD criteria. The risk of CSF in patients with MASLD was not significantly different (odds ratio [OR] = 1.07, 95% confidence interval [CI] = 0.30-3.83, p = 0.9180) compared with those without MASLD. MASLD was met by most of the US adolescents with SLD. Moreover, MASLD was not associated with higher prevalence of CSF among adolescents with SLD.
