About the study

The study is examining the health effects of gestational diabetes mellitus (GDM) intervention and medically tailored meals within home visiting. A large study is proposed that will include nearly a thousand pregnant or recently pregnant adults with recent GDM and who are from different regions and backgrounds. Two treatment approaches are compared, and both are in home visiting. One treatment group is receiving enhanced lifestyle support for GDM along with meals, and the other is receiving just the enhanced lifestyle support. The study will examine whether these interventions help reduce diabetes and pre-diabetes through 12 months postpartum, as well as other health factors like weight and blood pressure.
