Trial for Reducing Weight Retention in New Mums: a randomised controlled trial evaluating a low intensity, postpartum...

Area of Science:

• Obstetrics and Gynecology
• Public Health
• Behavioral Science

Background:

• Postpartum weight retention is linked to long-term obesity and adverse health outcomes.
• Women with a body mass index (BMI) > 25 kg m(-2) are at increased risk.
• Effective postpartum weight management is crucial for maternal health.

Purpose of the Study:

• To evaluate a postpartum weight management program for overweight/obese women.
• The program combined behavior change principles, low-intensity delivery, and nutrition information.
• To assess the program's impact on weight and other health markers.

Main Methods:

• Randomized controlled trial with supported care (SC) and enhanced care (EC) groups.
• EC group received nutrition assessment, goal-setting, and a 6-month correspondence intervention.
• Weight, anthropometry, diet, physical activity, and metabolic measures were assessed postpartum.

Main Results:

• No significant differences in weight change between EC and SC groups.
• Median weight change from pre-pregnancy to 6 months postpartum was +1.0 kg (EC) vs +2.3 kg (SC).
• Intervention group breastfed longer (180 vs 164 days), but engagement with self-monitoring sheets was low.

Conclusions:

• The low engagement suggests a need for improved strategies in postpartum weight management.
• High retention indicates continued interest in postpartum health among women.
• Future interventions require tailored approaches and enhanced behavior change support to mitigate chronic disease risk.
