A new prospective study involving nearly 400 pregnant women with gestational diabetes mellitus (GDM) reveals a significant link between non-traditional lipid parameters and adverse pregnancy outcomes (APOs). The analysis was published in Journal of Diabetes.

Among the 399 participants, 12% (48 women) experienced APOs such as preterm birth, hypertensive disorders, or fetal complications. The study found that several non-traditional lipid parameters were significantly linked to the risk of APOs. The atherogenic index of plasma (AIP) emerged as the strongest predictor, with an odds ratio (OR) of 3.873 (95% CI: 1.079–13.934; p = 0.037).

Interestingly, only one lipid marker, remnant cholesterol to HDL-C ratio (RC/HDL-C), did not show a significant association with APO risk.

The study also analyzed the metabolic mechanisms behind these associations and identified seven key serum metabolites that acted as mediators. These markers, mainly involved in the biosynthesis of unsaturated fatty acids, accounted for 21.9% to 39.4% of the association between lipid abnormalities and APOs.

Gene set variation analysis further confirmed this link, showing significant differences in the positive regulation of the unsaturated fatty acid biosynthesis pathway between women with APOs and those with normal pregnancy outcomes (p = 0.015).
