ObjectiveTo determine associations between lipid profiles in early pregnancy stratified by body mass index (BMI) and risk of developing gestational diabetes mellitus (GDM).Study DesignA total of 2488 healthy pregnant women were enrolled prospectively. Fasting plasma lipid profiles were measured at mean 11 weeks of gestation including triglycerides (TGs), total cholesterol, high-density lipoprotein (HDL), low-density lipoprotein (LDL), and cholesterol (CHO). We assessed early pregnancy maternal lipid concentrations in different tertiles in association with the risk of GDM stratified for BMI. Multivariable logistic regression analyses were used to estimate the relative risk of GDM by calculating odds ratios and 95% confidence intervals (CIs).ResultsIn univariate analyses, pregnant women with GDM had significantly increased serum TG, CHO, LDL concentrations, LDL/HDL ratio, and decreased LDL concentrations, compared to control groups, each P < .01, respectively. After adjustment for confounders, there was a 1.8-fold increase in risk for GDM in the lean group (95% CI: 1.2-2.7) and 2.7-fold increase in the obese group (95% CI: 1.1-6.6), respectively, if TG ≥ 1.58 mmol/L. About a 50% decrease in the risk of GDM was observed in lean women with HDL ≥ 2.22 mmol/L (95% CI: 0.3-0.9). No significant correlations of other lipid profiles with the risk of developing GDM were observed.ConclusionEarly pregnancy dyslipidemia is associated with the risk of developing GDM. Lean or obese women with higher TG concentrations are at an increased risk for developing GDM while lean women with high HDL are protected.© The Author(s) 2014.
