Abstract

Abstract : Objectives: Insulin resistance is central to the development of non‐alcoholic fatty liver disease (NAFLD), and gestational diabetes mellitus (GDM) is an early marker of insulin resistance. We hypothesized that a history of GDM would identify women at higher risk of NAFLD in middle age. Methods: Women from the multicenter Coronary Artery Risk Development in Young Adults (CARDIA) cohort study who delivered ≥1 birth, were free of diabetes prior to pregnancy(ies), and underwent CT quantification of hepatic steatosis 25 years following cohort entry (Y25: 2010–2011) were included ( n =1, 115). History of GDM by self‐report, validated in a subsample by review of antenatal glucose testing, and metabolic risk factors were assessed prospectively. NAFLD was defined by liver attenuation (LA)≤40 Hounsfield Units on CT scan after exclusion of other causes of hepatic steatosis. Results: Of 1, 115 women meeting selection criteria (57% black, 43% white, median age 25 years at baseline), 124 (11%) reported a history of GDM and 75 (7%) met the CT definition for NAFLD at year 25. The crude risk of NAFLD at the 25‐year visit was significantly higher in women with GDM compared to those without (14 vs. 5.8%, OR: 2.56, 95% CI: 1.44–4.55, P <0.01). History of GDM remained associated with NAFLD (OR: 2.29, 95% CI: 1.23–4.27, P =0.01) after adjustment for covariates in multivariable logistic regression. Addition of incident diabetes mellitus (DM) into the final model attenuated the association between GDM and NAFLD (OR: 1.48, 95% CI: 0.73–3.02, P =0.28). Conclusion: GDM is a risk marker for NAFLD and represents an opportunity to identify women at risk for NAFLD at a young age and may be mediated by the development of incident DM.
