This is a randomized controlled pilot study to evaluate the utility of the Garmin Vivosmart 5 wearable activity tracker in pregnancy. It will determine the feasibility of assessing physical activity in pregnant patients using wearable activity trackers and collect pilot data on the behavioral impact of wearable activity trackers on physical activity in pregnancy.

Pregnant participants will be given a Garmin Vivosmart 5 wearable activity tracker. They will be randomized 1:1 as to whether they are able to see their personal activity information or being blinded to it. Participants will complete a questionnaire on their physical activity levels before initiating use of the activity tracker and following delivery. Participants' physical activity data, satisfaction with the device, and gestational and delivery outcomes will be collected.

Inclusion Criteria:

• Establishing pregnancy care at Oregon Health & Science University
• Gestational age less than or equal to 24 weeks and 6 days
• Ability to read, write and speak English
• Ability to upload data either at home via a stable internet connection or in clinic

Exclusion Criteria:

• Non-English speaking
• Inability to wear wearable fitness technology due to allergy or sensory issues
• Inability to upload data from wearable fitness technology due to lack of stable internet connection or ability to come to clinic for upload via the research team in the timeframe required
• Inability to answer electronic questionnaires
• Specific contraindication to increased physical activity in pregnancy

Participants and research team members will know which arm participants in. Participants in the blinded arm will not have access to their data from the wearable activity tracker.
