Real-time glucose monitoring with group support during pregnancy

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

Participants early in pregnancy (<20 weeks) wear a continuous glucose monitor that streams real-time glucose levels to a smartphone app and join a mobile group chat for peer support. The intervention combines immediate glucose feedback with social messaging to prompt short-term actions (for example, walking or drinking water) and to share dietary and self-care tips. Investigators will track glucose patterns, engagement with the app and chat, and pregnancy outcomes to see if the combined approach helps maintain healthier blood glucose. The program is delivered via participants' own smartphones and run through Tufts Medical Center with follow-up through delivery.
