Pilot Testing a Mobile App to Designed to Increase Physical Activity Among Pregnant and Postpartum Women

The goal of this pilot project is to test the feasibility and potential efficacy of the evidence-based mHealth app (BumptUp) for improving physical activity and subsequent health outcomes (i.e. obesity, hypertension, insulin resistance) among pregnant and postpartum women in a rural community. In order to accomplish this goal, feasibility of the intervention protocol will be tested by the assessment of recruitment (how many participants eligible per month), retention (% of women who complete the study protocol), adherence to intervention (% of women who utilize the app), and acceptability (survey and one-on-one exit interviews) during pregnancy and postpartum. Potential efficacy will be determined by examining trends in data on physical activity levels (achieving the goal of 150 minutes per week of physical activity (surveys and accelerometry)) between groups. Other secondary outcomes will also be assessed: weight status, body composition, blood pressure, insulin resistance, fitness levels, mental health, and infant anthropometrics. Clinical hypotheses: 1. The mHealth program will be feasible as evidenced by high rates of enrollment, retention, and adherence, moderate-to-high levels of satisfaction, and low participant burden. 2. The mHealth intervention will show promise towards improving physical activity levels and other secondary outcomes in pregnant and postpartum women in a rural community.
