Healthy for Two, Healthy for You

Half of pregnant women are overweight or obese. Obesity disproportionately impacts low-income women and women of racial and ethnic minorities. Maternal obesity is linked with adverse perinatal outcomes, including gestational diabetes and preeclampsia, as well as longer-term health problems such as obesity in offspring and maternal cardiovascular disease. Pregnancy provides a unique opportunity to engage women in improving their health behaviors because women are motivated to protect the health of their babies and have frequent interactions with the healthcare system. Advances in behavioral weight management and obesity prevention have not yet been translated into real-world prenatal care settings. Our team was recently supported by the National Institute of Diabetes and Digestive and Kidney Diseases (NIDDK)-funded Nutrition and Obesity Research Center Pilot and Feasibility program to adapt an evidence-based telephonic health coaching program for pregnant women. Investigators conducted 20 in-depth interviews with patients and providers to gain valuable feedback to inform the intervention design and delivery, and have put together a multi-disciplinary team to adapt the intervention. Investiagtors developed the intervention specific for pregnancy and postpartum based on this feedback and are testing the intervention, Healthy for Two / Healthy for You, to assess feasibility and acceptability.
