Antecedentes: La esteatohepatitis no alcohólica (EHNA), relacionada con la obesidad, es cada vez más prevalente, especialmente en Perú, donde los datos son limitados. Se ha sugerido que el hipotiroidismo contribuye al desarrollo de EHNA a través de mecanismos como disfunción mitocondrial, estrés oxidativo y alteraciones en la leptina. Objetivo: Evaluar la asociación entre hipotiroidismo y EHNA en adultos obesos sin diabetes mellitus. Métodos: Estudio transversal en adultos que buscan cirugía bariátrica en un centro privado en Perú. EHNA se definió por biopsia e hipotiroidismo por historia clínica o laboratorios. Se emplearon modelos lineales generalizados (GLM) para medir las razones de prevalencia (RP), ajustadas por factores de confusión. Resultados: Se incluyeron 398 pacientes; edad media 34,3 años, 70,6% mujeres. Las prevalencias de hipotiroidismo y EHNA fueron 9,5% y 84%, respectivamente. El hipotiroidismo se asoció con una prevalencia 1,18 veces mayor de EHNA (RP ajustada: 1,18; IC 95%: 1,07-1,30, p=0,001). Conclusión: El hipotiroidismo se asoció significativamente con EHNA en adultos obesos sin diabetes, sugiriendo un papel crucial de la disfunción tiroidea en la patogénesis de EHNA.Background: Non-alcoholic steatohepatitis (NASH), often associated with obesity, is increasingly prevalent, especially in Peru, where data are limited. Hypothyroidism has been suggested to contribute to NASH development through mechanisms such as mitochondrial dysfunction, oxidative stress, and leptin alterations. Objective: To evaluate the association between hypothyroidism and NASH in obese adults without diabetes mellitus. Methods: Cross-sectional study of adults seeking bariatric surgery at a private center in Peru. NASH was defined by biopsy results, and hypothyroidism by clinical history or laboratory values. Generalized linear models were used to calculate prevalence ratios (PR), adjusted for confounding factors. Results: A total of 398 patients were included; mean age was 34.3 years, and 70.6% were women. The prevalences of hypothyroidism and NASH were 9.5% and 84%, respectively. Hypothyroidism was associated with a 1.18-fold higher prevalence of NASH (adjusted PR: 1.18; 95% CI: 1.07-1.30, p=0.001). Conclusion: Hypothyroidism was significantly associated with NASH in obese adults without diabetes, suggesting a crucial role of thyroid dysfunction in NASH pathogenesis.
