Insights
High preconception triglyceride levels increase the risk of hypertensive disorders and gestational diabetes during pregnancy. Improving maternal cardiovascular health before pregnancy may reduce these risks.
Area of Science:
- Cardiovascular health
- Reproductive medicine
- Public health
Background:
- Pregnancy complications are linked to adverse maternal and infant outcomes.
- Preconception cardiovascular risk factors' impact on pregnancy is understudied.
Purpose of the Study:
- To investigate the association between preconception cardiovascular risk factors and pregnancy complications.
- To identify modifiable risk factors for improved pregnancy outcomes.
Main Methods:
- Utilized data from the Cardiovascular Risk in Young Finns Study linked with birth registry data.
- Analyzed preconception lipid profiles, blood pressure, insulin, and glucose levels.
- Employed regression models to assess predictors of gestational age, birthweight, and pregnancy disorders.
Main Results:
- Elevated triglyceride levels were associated with increased risk of hypertensive disorders and gestational diabetes.
- Systolic blood pressure showed a trend towards predicting preterm birth and small-for-gestational-age infants.
Conclusions:
- Preconception high lipid levels, particularly triglycerides, predict increased risk of preeclampsia and gestational diabetes.
- Maternal pre-pregnancy conditions may explain links between pregnancy complications and later cardiovascular disease.
- Interventions promoting preconception cardiovascular health could mitigate pregnancy complication risks.
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.
