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).

Do preconception cardiovascular risk factors predict pregnancy complications in primiparous women?
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.
Effect estimate: aRR 1.70 (95% CI 1.08-2.65)
BACKGROUND: Pregnancy-related cardiovascular conditions are associated with both poorer pregnancy outcomes and cardiovascular disease later in life. Little is known about the relationship between preconception cardiovascular risk factor levels and pregnancy complications. METHODS: Data from the Cardiovascular Risk in Young Finns Study were linked with birth registry data for 1142 primiparous women. Age-standardized levels of total cholesterol, high-density lipoprotein cholesterol, low-density lipoprotein cholesterol, triglycerides, blood pressure, insulin, and glucose from the study visit prior to last menstrual period were calculated. These factors were examined as predictors of 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 diabetes, using linear and Poisson regression with adjustment for age, body mass index, smoking, and socioeconomic status. RESULTS: Higher triglycerides were associated with a higher risk of hypertensive disorders (adjusted risk ratio aRR = 1.42 95% confidence interval (CI) = 0.90-2.23), preeclampsia (1.70 1.08-2.65), and gestational diabetes (1.68 1.25-2.25). After removing women with pregnancy complications (n = 30), the estimated aRR for the association between systolic blood pressure and preterm birth was 1.23 (95% CI = 0.99-1.54); for HDL-c and low birthweight, 0.97 (0.73-1.28); for diastolic blood pressure and small-for-gestational-age, 0.98 (0.81-1.20); and for systolic blood pressure and small-for-gestational-age, 1.18 (0.97-1.45). CONCLUSIONS: High lipid levels before pregnancy predict an increased risk of preeclampsia and gestational diabetes. Reported associations between these pregnancy complications and later cardiovascular disease of the mother are probably explained, at least in part, by maternal conditions that precede pregnancy. Interventions to improve cardiovascular health before pregnancy may reduce risk of pregnancy complications.
Harville et al. (Sat,) 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).
