Postpartum Physical Activity Intervention Among Women With Gestational Diabetes: A Randomized Controlled Trial

Area of Science:

• Reproductive Health and Endocrinology
• Metabolic and Cardiovascular Health
• Clinical Trials and Intervention Studies

Background:

• Gestational diabetes mellitus (GDM) increases risks for maternal and infant health complications.
• Postpartum recovery and metabolic health are critical for women with a history of GDM.
• Evidence-based interventions are needed to improve postpartum outcomes for GDM patients.

Purpose of the Study:

• To evaluate the efficacy of wearing ankle weights during daily activities in postpartum women with GDM.
• To assess the impact of ankle weights on body weight, body composition, and key biomarkers.
• To compare outcomes between an ankle weight intervention group and a standard-of-care control group.

Main Methods:

• A parallel two-arm, randomized controlled trial (RCT) involving postpartum women with a history of GDM.
• Intervention group wore 1.1 kg ankle weights for 2 hours/day from 25-35 to 190-210 days postpartum.
• Primary outcome: body weight. Secondary outcomes: body composition, glycemic, lipid, and inflammatory biomarkers. Analyzed using linear mixed models.

Main Results:

• No significant differences in weight change (ANK: 3.8 kg vs. CTRL: 2.2 kg) or percent body fat change were observed.
• Both groups showed reductions in total cholesterol, with no significant difference attributable to the intervention.
• The ankle weight intervention did not yield significant improvements in other secondary outcomes compared to standard care.

Conclusions:

• Wearing ankle weights during daily postpartum activities did not significantly improve body weight, composition, or metabolic biomarkers in women with GDM.
• The intervention demonstrated no additional benefit compared to standard postpartum care for this population.
• Further research may explore different physical activity interventions or durations for postpartum GDM management.
