What this trial studies

This study investigates the effects of omega-3 fatty acid supplementation on triglyceride levels in pregnant women. It aims to determine whether these supplements can help manage elevated triglyceride levels, which can be common during pregnancy and may lead to complications such as having a larger-than-average baby. Participants will be given either omega-3 supplements or a control substance (safflower oil) to assess the impact on triglyceride levels. The study focuses on women with specific pre-pregnancy BMI and triglyceride levels.

Who should consider this trial

Good fit: Ideal candidates are pregnant women aged 21-39 with a pre-pregnancy BMI of 28-39 and fasting triglyceride levels of 120 mg/dL or higher by 15 weeks of pregnancy.

Not a fit: Patients with pre-gestational diabetes, a history of gestational diabetes, or other specified health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help manage triglyceride levels in pregnant women, potentially reducing risks associated with high triglycerides.

How similar studies have performed: While there is ongoing research into omega-3 fatty acids, this specific approach to managing triglyceride levels in pregnancy is relatively novel.
