- Abstract
Objective: To evaluate whether the associations of maternal liver dysfunction and liver function biomarkers (LFBs) with gestational diabetes mellitus (GDM) are independent of overweight. Design Prospective cohort study. Methods: A sub‐cohort of pregnant women with seven LFBs examined at 9–13 weeks of gestation and with complete GDM evaluation at mid‐gestation were extracted from the prospective Shanghai Preconception Cohort Study. Associations of liver dysfunction, defined as having any elevated LFB levels, and individual LFB levels with GDM incidence were assessed by adjusting body mass index and other covariates in the multivariable logistic regression model. Odds ratios (ORs) and 95% CI were reported. Main outcome measures: Incident GDM. Results: Among 6211 pregnant women, 975 (15.7%) developed GDM. Liver dysfunction was associated with increased odds of GDM (OR 1.63; 95% CI 1.38–1.92). This association persisted after adjustment for BMI (adjusted OR [aOR] 1.37; 95% CI 1.15–1.63). Higher γ‐glutamyl transferase, alanine aminotransferase, alkaline phosphatase, and albumin levels were also linked with GDM (aOR per 1 SD: 1.15, 95% CI 1.08–1.23; 1.10, 1.03–1.17; 1.21, 1.13–1.29 and 1.19, 1.11–1.27, respectively). Similar magnitudes of associations were observed between normal weight and overweight pregnant women. Conclusion: Maternal liver dysfunction in early pregnancy predisposes women to subsequent GDM, and this association is independent of being overweight preconception. Our findings of an increased risk even in normal‐weight pregnant women adds new mechanistic insights about the pathophysiological role of liver function in GDM aetiology. Maternal liver dysfunction in early pregnancy is associated with GDM incidence independent of preconception overweight. Maternal liver dysfunction in early pregnancy is associated with GDM incidence independent of preconception overweight.
