Can a Partner's support lower diabetes risk after gestational diabetes?
NCT ID NCT07762625
First seen Aug 13, 2026 · Last updated Aug 14, 2026 · Updated 1 time
Summary
This trial tests whether a lifestyle program that includes the partner can help women who had gestational diabetes improve their weight and blood sugar control. Participants receive three months of health education on diet, physical activity, and stress management, with one group also getting couple-focused support and communication tools. The study compares this couple-based approach to a woman-only program to see if spousal involvement leads to greater health improvements.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- Couple-based collaborative lifestyle intervention (health education, physical activity, stress management, and couple support)
- What this could lead to
- If effective, this approach could offer a practical, partner-inclusive strategy to reduce diabetes risk and improve health behaviors in women after gestational diabetes.
- What could go wrong
- The trial is relatively small and the intervention is behavioral, so results may vary. Success depends on couple engagement and long-term adherence, which can be challenging.
