Objective:

To examine associations between maternal body mass index (BMI), BMI-stratified gestational weight gain (GWG), and cardiovascular disease (CVD) risk in offspring.

Approach:

• Study Design: A nationwide cohort study utilizing the Swedish Medical Birth Register (MBR) to analyze maternal BMI and GWG in relation to offspring CVD risk.
• Data Collection: Maternal height and weight were recorded in early pregnancy, and GWG was calculated from these measurements. Offspring health outcomes were tracked using various national registries.
• Outcome Measures: The primary outcome was major CVD in offspring, including various cardiovascular conditions, assessed through medical records.
• Statistical Analysis: Cox proportional hazards regression was used to evaluate associations, adjusting for potential confounders.

Key Findings:

• Maternal overweight and obesity are prevalent among women of reproductive age and are linked to adverse birth outcomes.
• Inadequate and excessive gestational weight gain have become more common, with implications for offspring cardiometabolic profiles.
• The study clarifies the relationship between maternal BMI, GWG, and the risk of CVD in offspring.

Interpretation:

The study examines how maternal health factors during pregnancy may influence cardiovascular health in their children.

Limitations:

• Previous studies on this topic had small sample sizes and limited follow-up durations.
• The study may be limited by the accuracy of self-reported maternal height and weight.

Conclusion:

The findings contribute to understanding the prenatal origins of cardiovascular disease in younger populations.
