Mindfulness and Wearable Biosensors to Prevent Hypertensive Disorders of Pregnancy

Mindfulness and Wearable Biosensors to Prevent Hypertensive Disorders of Pregnancy Study: MINDBP

The MINDBP study will enroll 90 pregnant women at risk for HDP across two sites (MCW and Brown) and randomize them to: (1) mindfulness training (MT) plus wearable biosensors, (2) MT alone, or (3) routine prenatal care. MT participants will receive 8 weekly phone-based MT sessions plus two booster sessions at 1 and 2 months post-intervention. The primary outcome is study feasibility.

The MINDBP study will enroll 90 pregnant women at risk for HDP across two sites (MCW and Brown) and randomize them to: (1) MT + wearable biosensors, (2) MT alone, or (3) routine prenatal care. MT participants will receive 8 weekly phone-based MT sessions plus two booster sessions at 1 and 2 months post-intervention. All participants will wear Garmin Vivoactive 4 watches. Blood pressure, heart rate, heart rate variability, perceived stress, and pregnancy-related anxiety will be assessed at baseline (≤16 weeks), post-intervention (~24 weeks), and after each booster (~28 and 32 weeks). Feasibility, fidelity, and acceptability outcomes will be assessed after each post-intervention
