We will be conducting focus groups and informant interviews to determine the DPP modifications necessary for adapting to the post-partum lifestyles of women with a recent history of GDM. Subjects will attend a 1 hour focus group or phone interview where they will be encouraged to respond to the facilitators' questions and to each other's comments on topics such as: gestational diabetes, healthy eating, exercise, and other type 2 diabetes prevention related activities. Working with a variety of health care providers, including endocrinologists, obstetricians and nurse-practitioners, we will identify and enroll up to 60 women total who are either current GDM patients at BWH or have a recent history of GDM who have delivered at Brigham and Women's Hospital in the last 5 years.
