The overall goal of this project is to develop and evaluate a pilot lifestyle intervention to prevent the occurrence of Gestational Diabetes (GDM). GDM among pregnant, overweight Hispanic women at increased risk for GDM. A total of 66 women will be recruited and randomized in pregnancy to a lifestyle intervention or standard of care group. The lifestyle intervention will be a 6 month program consisting of monthly in-person educational sessions and biweekly telephone booster calls, which will continue until delivery.
