Trial results for an antenatal obesity treatment aimed at preventing excessive weight gain in pregnancy were posted on ClinicalTrials.gov on 2026-01-21. The study found that 119 participants in the antenatal obesity treatment group experienced excessive gestational weight gain, compared to 126 in the standard care group.
Background
Obesity and overweight status during pregnancy are significant health concerns. Excessive gestational weight gain can lead to complications for both the mother and the baby. Current approaches often involve standard care provided through programs like WIC (Special Supplemental Nutrition Program for Women, Infants, and Children). This study aimed to evaluate the impact of an integrated antenatal obesity treatment on gestational weight gain within the Philadelphia WIC framework.
Trial design
This completed study enrolled 416 participants. The trial investigated conditions including Obesity, Overweight, and Pregnancy Related factors. The study compared an Antenatal Obesity Treatment (AO) integrated into Philadelphia WIC against WIC Standard Care (SC).
Key results
The study reported on two key measurements:
- Percentage of Women With Excessive Gestational Weight Gain:
- In the WIC Standard Care (SC) group, 126 participants experienced excessive gestational weight gain.
- In the Antenatal Obesity Treatment (AO) group, 119 participants experienced excessive gestational weight gain.
- Change in Maternal Weight:
- The median change in maternal weight for the WIC Standard Care (SC) group was 7.6 kilograms.
- The median change in maternal weight for the Antenatal Obesity Treatment (AO) group was 7.2 kilograms.
What this means
The results suggest that integrating an antenatal obesity treatment into WIC may lead to a modest reduction in excessive gestational weight gain and a slightly lower median maternal weight gain compared to standard WIC care. For patients with obesity or overweight status during pregnancy, this approach could offer a beneficial intervention to manage weight gain, potentially improving maternal and infant health outcomes.
