Maternal childhood cardiometabolic risk factors and pregnancy complications

Area of Science:

• Cardiovascular Health
• Reproductive Health
• Pediatric Health

Background:

• Childhood health's long-term impact on adult outcomes is under-researched.
• Cardiometabolic risk factors in youth may influence later-life health.
• Pregnancy complications like hypertension and diabetes have significant maternal and fetal implications.

Purpose of the Study:

• To investigate the association between childhood cardiometabolic indicators and pregnancy complications.
• To determine if early-life body mass index (BMI), blood pressure, and insulin levels predict adverse pregnancy outcomes.
• To explore the mediating role of blood pressure in the relationship between childhood BMI and pregnancy-induced hypertension.

Main Methods:

• Utilized data from 755 women in the Bogalusa Heart Study.
• Assessed childhood measurements including BMI, blood pressure (SBP, DBP), cholesterol, triglycerides, insulin, and glucose.
• Employed longitudinal growth models and Log-Poisson regression to analyze relationships between childhood indicators and pregnancy outcomes.

Main Results:

• Elevated childhood insulin levels were linked to a 10%-15% increased risk for all three pregnancy complications.
• Childhood systolic blood pressure (SBP) was associated with preeclampsia.
• Childhood SBP, diastolic blood pressure (DBP), and BMI predicted pregnancy-induced hypertension, with blood pressure mediating the BMI association.

Conclusions:

• Early-life cardiometabolic profiles have a significant long-term influence on pregnancy complications.
• Childhood cardiometabolic health is a critical determinant of maternal health during pregnancy.
• Interventions targeting childhood cardiometabolic health may reduce risks of adverse pregnancy outcomes.
