Psychobiological Interventions in Pregnancy

The step count goal will be discussed at the beginning of the study, and participants will be able to see their step count on the Actigraph watch to facilitate achieving this goal. All participants will receive weekly reminders that are tailored for their intervention arm. Intervention group participants will also receive a step count diary with motivational ideas of how to obtain step goals, which will be reviewed with a study team member every 2 weeks.

Both groups will wear the watch. Adherence will be assessed via step counts from accelerometer watch.
