The Effect of a Supervised Exercise Program Throughout Pregnancy on Longitudinal Lipid Profile Changes: A Randomized...

Area of Science:

• Obstetrics and Gynecology
• Cardiovascular Health
• Exercise Physiology

Background:

• Maternal lipid profiles undergo significant changes during pregnancy.
• Maintaining a healthy lipid profile is crucial for both maternal and fetal well-being.
• The impact of supervised exercise programs on these changes requires further investigation.

Purpose of the Study:

• To determine if a supervised exercise program during pregnancy modifies the maternal lipid profile.
• To analyze changes in total cholesterol, triglycerides, HDL-C, and LDL-C.

Main Methods:

• Secondary analysis of a multicenter randomized controlled trial (RCT).
• Participants randomized to supervised exercise (n=92) or usual activity (n=90).
• Lipid profiles assessed at multiple time points: second trimester, third trimester, and postpartum.

Main Results:

• Longitudinal analysis revealed a significant increase in HDL-C in the exercise group (+3.24 mg/dl, P=0.041), persisting postpartum.
• A trend towards lower LDL-C was observed in the exercise group (-6.02 mg/dl, P=0.099), but did not reach statistical significance.
• No significant between-group differences in overall lipid profiles were found at specific trimesters or postpartum.

Conclusions:

• Supervised exercise during pregnancy may positively influence maternal lipid profiles, specifically by increasing HDL-C.
• The potential for reducing LDL-C warrants further investigation.
• Larger studies are recommended to confirm these findings and explore clinical implications.
