About the trial
What the trial wants to find out
The purpose of the research is to learn whether wearing a continuous glucose monitor that shows blood glucose levels in real time on a smart phone app and participating in a group chat with other research participants will help participants keep a healthy blood glucose level during pregnancy.
Read full original descriptionShow less
High levels of blood glucose during pregnancy can lead to health problems during and after pregnancy. It may also increase the risk for health problems for the developing baby.
The investigators think our program might be a new way to help some people maintain a healthy blood glucose level during pregnancy. When pregnant people know their blood glucose levels are high, they can do things like exercise or drink water to bring their blood glucose levels down. They can also learn what foods to eat to maintain healthy blood glucose levels, and what foods to avoid. The investigators think being in a group chat with other pregnant individuals will allow participants to support and learn from each other. Pregnant individuals should also work with their healthcare providers to manage their blood glucose levels.
The 2 groups in the trial
- Group 1- Group chat interventionTreatment being tested
Participants in group 1 will be randomized to wear a real-time continuous glucose monitor for 14 days and participate in a secure mobile-based group chat where they will provide and receive social support for glucose management. Participants will be in the group chat for 60 days.
Treatment: Mobile-based social support and Real-time continuous glucose monitoring
- Group 2- No group chat interventionTreatment being tested
Participants in group 2 will be randomized to wear a real-time continuous glucose monitor for 14 days.
Treatment: Real-time continuous glucose monitoring
