Abstract

Abstract : Nonalcoholic fatty liver disease (NAFLD), depression, and anxiety disorders are frequent diseases, and data on mutual influence are inconsistent. The aim of this study was to explore the incidence of depression and anxiety in a large primary care cohort in Germany and to study the impact of NAFLD over a 10‐year time frame. Patients with NAFLD diagnosed between 2010 and 2015 were matched to a cohort without NAFLD controlling for age, sex, physician, index year, and Charlson comorbidity index. The primary outcome of the study was the incidence of depression, anxiety, and first prescription of antidepressant drugs. We compared 19, 871 patients with NAFLD to 19, 871 matched controls. Within 10 years of the index date, 21.2% of patients with NAFLD and 18.2% of controls were diagnosed with depression ( P < 0.001). On regression analysis, the hazard ratio (HR) for incidence of depression was 1.21 ( P < 0.001). This association was similar for the endpoint of the first prescription of antidepressant drugs (HR, 1.21; P < 0.001). Anxiety disorders were diagnosed in 7.9% of patients with NAFLD and 6.5% of controls during the observation time ( P = 0.003). The HR for incidence of anxiety was 1.23 ( P < 0.001). This association remained significant in women ( P < 0.001), while there was only a trend in men (HR, 1.15; 95% confidence interval, 0.99‐1.34; P < 0.067). The risk of developing anxiety disorders was higher in younger patients. Conclusion: NAFLD constitutes an independent risk factor for emerging depression and anxiety even after controlling for confounding comorbidities.
