Cardiovascular Risk Factors in Offspring of Preeclamptic Pregnancies-Systematic Review and Meta-Analysis

Area of Science:

• Obstetrics and Gynecology
• Pediatrics
• Cardiovascular Medicine

Background:

• Preeclampsia is a pregnancy complication associated with long-term maternal health risks.
• Emerging evidence suggests potential long-term effects on offspring cardiovascular health.

Purpose of the Study:

• To systematically evaluate the evidence linking in utero preeclampsia exposure to cardiovascular disease (CVD) risk factors in children and young adults.

Main Methods:

• A comprehensive literature search was conducted across major biomedical databases (PubMed, CINAHL, Cochrane Library, EMBASE) up to June 2018.
• Included studies were prospective or retrospective, comparing CVD risk factors in preeclampsia-exposed individuals with controls.
• Data extracted included blood pressure, lipid profile, glucose, insulin, BMI, and endothelial function.

Main Results:

• Analysis of 36 studies involving 53,029 individuals revealed significant associations.
• In utero preeclampsia exposure was linked to higher mean systolic (5.17 mm Hg) and diastolic blood pressure (4.06 mm Hg).
• A greater mean body mass index (0.36 kg/m²) was also observed in exposed individuals during childhood/young adulthood.

Conclusions:

• Offspring exposed to preeclampsia in utero exhibit identifiable CVD risk factors in childhood and young adulthood.
• Routine blood pressure screening for these children is recommended to identify those needing early intervention.
• Proactive strategies can mitigate the increased risk of later-life cardiovascular disease.
