Brief summary
The purpose of this intervention is to help new mothers who had elevated blood pressure during pregnancy become more physically active after birth. The investigators will connect data from FitBits to the electronic health record. Women will then get weekly messages with feedback and goals to help them stay active. The investigators will test if the intervention improves step counts and blood pressure after pregnancy. The investigators will also test if the intervention is feasible and enjoyed by postpartum women.
Interventions
BEHAVIORALPatient Portal Messaging
Participants will receive weekly messages via their patient portal including feedback on their step counts and step count goals based on data from their FitBits
BEHAVIORALFitBit EHR Linkage
Participants will receive FitBits and link this step count data with the Electronic Health Record (EHR)

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Feasibility of Recruitment | From enrollment to the end of the 24 week intervention | Number of participants enrolled in the intervention |
| Feasibility of Participant Retention | At study weeks 12 and 24 | Percent of enrolled participants who continue to participate in the intervention |
| Feasibility of FitBit+EHR linkage | From enrollment to the end of the 24 week intervention | Percent of intervention days FitBit data are linked to the Electronic Health Record |
| Feasibility of Intervention Messaging | From enrollment to the end of the 24 week intervention | Percent of weekly messages that are read by participants |
| Acceptability of the Intervention | Study week 24 | Participants will fill out a survey to assess the extent to which they were satisfied with individual intervention components including FitBit usage, portal messaging, blood pressure and weight assessments, surveys, intervention length and intervention delivery. Each component will be rated on a 5-point Likert Scale in which 1 represents very dissatisfied (lowest score) and 5 represents very satisfied (highest score). |
