Conditions pregnancy, weight gain
Treatments behavioral intervention, usual prenatal care
Sponsor Stanford University
Start date March 2014
End date August 2016
Trial size 55 participants
Trial identifier NCT02142452, 28810


The investigators will test the efficacy of a tailored behavioral lifestyle modification program to support cardiovascular health in postpartum women with excessive gestational weight gain. This program will include a mobile health texting component postpartum to support changes in nutrition and physical activity. The investigators will randomize women into either the control arm (usual care) or the intervention (usual care + mobile health program postpartum). The women will be recruited during their 3rd trimester once they have been identified as gaining too much weight according to the 2009 IOM guidelines during pregnancy.

Study Design

Allocation randomized
Endpoint classification efficacy study
Intervention model parallel assignment
Masking open label
Primary purpose prevention
Behavioral intervention. Women with excessive weight gain in pregnancy will be recruited in their 3rd trimester. They will begin with a 5 week group session on weight management. After they deliver the baby, they will begin receiving text messages supporting behavior change they learned in their 3rd trimester. They will follow up at 6 weeks postpartum and 4 months postpartum.
behavioral intervention
Behavioral intervention will include a group class for women in their 3rd trimester followed by a mobile texting program to support behavior change postpartum.
(Placebo Comparator)
Women will receive usual prenatal care from their OB. Postpartum, they will receive a monthly newsletter relevant to the new mother on her nutrition and physical activity. They will be followed at 6 weeks postpartum and 4 months postpartum.
