Variables associated with increased incidence of non-alcoholic fatty liver disease (NAFLD) in patients with type 2 diabetes

Abstract

Introduction Type 2 diabetes (T2D) and non-alcoholic fatty liver disease (NAFLD) show a rapidly increasing incidence worldwide. Although both diseases often occur in the same patient population, their mutual influence is not fully understood. We therefore aimed at analyzing the impact of T2D on the incidence of NAFLD in a large cohort of outpatients in Germany.Research design and methods 32 201 patients with T2D diagnosed between 2012 and 2018 were identified in the IQVIA Disease Analyzer database. Probability of NAFLD was analyzed using Cox regression models.Results The cumulative incidence of NAFLD within the 7-year observation period was 4.3%. The probability of NAFLD was significantly higher among patients with T2D with increased body mass index but not hemoglobin A1c. Prescriptions of sodium-glucose cotransporter-2 inhibitors (HR: 0.54, 95% CI 0.45 to 0.64), glucagon-like peptide-1 receptor antagonists (HR: 0.65, 95% CI 0.52 to 0.81), and insulin (HR: 0.72, 95% CI 0.62 to 0.8) were significantly associated with lower incidence of NAFLD.Conclusion Our data from a large population-based cohort of patients with T2D identified sociodemographic and therapeutic parameters associated with NAFLD incidence in patients with T2D which should be taken into account for novel therapeutic concepts.
