Can family power prevent diabetes? trial tests group approach
NCT ID NCT07815236
First seen Sep 11, 2026 · Last updated Sep 11, 2026
Summary
Researchers are testing whether adding family health history and family participation to the standard Diabetes Prevention Program helps adults with prediabetes. The trial enrolls 400 adults with prediabetes and a family member who joins them. Participants are assigned to either the family-enhanced program or the standard program. The study measures weight loss, blood sugar changes, and session attendance over 12 months, and also checks whether family members see health benefits.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- a family-enhanced Diabetes Prevention Program that adds family health history and family skill-building sessions to the standard behavioral weight loss program
- What this could lead to
- If it works, this could give diabetes prevention programs a new way to help people by involving family members, potentially improving weight loss and blood sugar for both participants and their relatives.
- What could go wrong
- This is a mid-stage trial, so results are not guaranteed. Family involvement may not improve outcomes more than the standard program, and participants must attend in-person sessions, which can be hard for some families.
