Optimizing Health From Pregnancy Through One Year Postpartum

December 29, 2020


The goal of this study is to improve the lives of pregnant women who are overweight by determining if intervention during pregnancy is enough to maintain optimal weight, or if it’s necessary to continue intervention to the postpartum period. 


Study Information

This study is conducted with 300 participants, all of whom are pregnant women 14 years and older and are at or earlier than 18 weeks and 4 days pregnant. The participants are divided into four groups. Group 1 will receive the study intervention during pregnancy, but will receive normal postpartum care. Study intervention includes 10 sessions conducted in person at obstetric appointments. Women will receive nutritional and dietary guidelines for maintaining health and optimal weight while pregnant. They will complete forms for self monitoring to identify cues that indicate unhealthy behaviors that will then help them modify those behaviors. Personal beliefs about body weight and eating during pregnancy will be discussed, as well as the effects of physical activity on body weight, health, and mood. Group 2 will receive that same study intervention both during pregnancy, and during the postpartum period. Postpartum treatment will consist of sessions over the phone or in person done 2 times a week over 24 weeks. Treatment will consist of additional support text messages and phone calls between sessions, and sessions will involve discussion on weight, physical activity, eating, and psychosocial issues. Group 3 will receive normal care during pregnancy, but the study treatment during the postpartum period. Group 4 will receive standard care during both pregnancy and the postpartum period.

  • Has a prenatal BMI of greater than or equal to 25
