A new meta-analysis of 12 studies suggests that certain blood lipid levels may be linked to a higher risk of preeclampsia, a serious pregnancy complication. Researchers analyzed data from 822 studies and found that women with preeclampsia had significantly lower levels of HDL (good cholesterol) and higher levels of LDL (bad cholesterol), triglycerides, and total cholesterol compared to healthy pregnant women. The differences remained even after adjusting for body mass index, though the effects were modest.
The study also found that women with preeclampsia had nearly four times the odds of adverse pregnancy outcomes, such as preterm birth or low birth weight. However, because the studies were observational, the findings do not prove that abnormal lipids cause preeclampsia. Other factors could explain the link.
This research adds to evidence that blood lipid monitoring might help identify women at risk, but it is not yet a definitive tool. Pregnant women should not change their care based on these results alone. The findings highlight the need for more research to understand the role of lipids in preeclampsia.
