Research + Clinical Trials


Randomized control trial to investigate the effect of a smartphone application for gestational diabetes management on postpartum glucose intolerance

The use of smartphone applications as gestational diabetes management is an emerging area of research. We are hoping to explore possible benefits of the Malama smartphone app to help manage your blood sugar during pregnancy. We also hope to explore how you recover from gestational diabetes shortly after your baby's birth by asking you to do a blood sugar test (HA1c) and a glucose tolerance test.

Participants will be randomized to using the Malama app to track blood sugars or traditional logs such as pen-and-paper. If assigned to use Malama, you will be asked to complete a patient experience survey.
