Abstract

BACKGROUND: An association between depression and metabolic dysfunction-associated fatty liver disease (MAFLD) appears logical on the basis of previous observations linking depression to nonalcoholic fatty liver disease. We aim to investigate the association between depression and MAFLD and significant fibrosis.METHODS: This cross-sectional study was conducted on data from National Health and Nutrition Examination Survey, 2017 to March 2020 Pre-pandemic dataset. Depression and depression-related functional impairment were assessed using the Patient Health Questionnaire (PHQ-9). MAFLD, based on the criteria proposed by an international expert panel, and significant fibrosis were defined by transient elastography.RESULTS: Of the 3327 individuals (mean age: 46.9?years, 50.2?% men), the prevalence of depression and functional impairment due to depression was higher among individuals with MAFLD or significant fibrosis than among those without. Individuals with depression were approximately 70?% more likely to have MAFLD than those without. In multivariable analyses, depression was associated with an increased risk of MAFLD (odds ratio [OR]: 1.77, 95?% confidence interval [CI]:1.33-2.36 for =263?dB/m and OR: 1.70, 95?% CI: 1.20-2.41 for =285?dB/m). These associations were more pronounced in postmenopausal women than premenopausal women. In terms of significant fibrosis, depression remained an independent predictor of significant fibrosis; however, it attenuated after adjustment for body mass index.LIMITATIONS: Temporal causality and residual confounders could not be entirely investigated due to the study design.CONCLUSIONS: Depression was independently associated with MAFLD and significant fibrosis in a nationally representative sample of adults in the US.
