Preconception Cardiovascular Risk Factors and Pregnancy Outcome
Key result
Higher preconception triglyceride levels were associated with an increased risk of preeclampsia (aRR 1.70; 95% CI 1.08-2.65) and gestational diabetes (aRR 1.68; 95% CI 1.25-2.25).
Why the study?
Do preconception cardiovascular risk factors predict pregnancy complications in primiparous women?
Population

Implication
Preconception triglycerides may flag higher preeclampsia and GDM risk in primiparas; leaves open whether lipid intervention improves outcomes.

Intervention
Preconception cardiovascular risk factors (total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, blood pressure, insulin, and glucose)
O
Outcome
Gestational age, preterm birth (<37 weeks), birthweight, low birthweight (<2500 g), small-for-gestational-age (weight <10th percentile for gestational age), hypertensive disorders of pregnancy, and gestational diabeteshard clinical
Main Result
Effect estimate: aRR 1.70 (95% CI 1.08-2.65)
High preconception lipid levels, particularly triglycerides, predict an increased risk of preeclampsia and gestational diabetes, suggesting that preconception cardiovascular health interventions may reduce pregnancy complications.
Cite This Study
Harville et al. (2011) conducted a cohort in Pregnancy complications (n=1,142). Preconception cardiovascular risk factors (e.g., triglycerides) was evaluated on Preeclampsia (aRR 1.70, 95% CI 1.08-2.65). Higher preconception triglyceride levels were associated with an increased risk of preeclampsia (aRR 1.70; 95% CI 1.08-2.65) and gestational diabetes (aRR 1.68; 95% CI 1.25-2.25).
