Summary

Hypertensive disorders of pregnancy (HDP) are the most common medical condition affecting pregnancy and a leading cause of maternal morbidity and mortality in the Unites States. HDP also increase lifetime cardiac disease risk in women and infants. Current interventions to prevent HDP are limited, and interventions that do not include medications are minimally effective at preventing HDP. Mindfulness interventions hold promise as a intervention to prevent HDP that does not require pregnant women to take medications. Past research shows that mindfulness interventions reduce blood pressure in adults with hypertension and pre-hypertension. However, past studies of mindfulness interventions for pregnant women have not allowed women at risk for HDP to participate. The preliminary study of prenatal mindfulness training for women at risk for HDP demonstrated benefit on maternal blood pressure and fetal growth. However, the mechanisms explaining effects of prenatal mindfulness training on risk for HDP are unknown. Building upon these promising preliminary findings, the proposed clinical trial will measure daily experiences of stress, physiological reactivity to stress, and interpersonal processes before and after prenatal mindfulness training. The investigators hypothesize that mindfulness training will impact these processes, which may lead to improved maternal cardiovascular parameters and reduced risk for HDP. N=150 pregnant women at risk for HDP will be randomized to an 8-week phone-delivered mindfulness intervention or usual care. For every participant, we will measure maternal cardiovascular parameters (24-hour blood pressure and uterine artery resistance values by ultrasound Doppler) before and after the 8-week period. All participants will complete surveys of daily experiences for 2 weeks before and after the 8-week period to evaluate mechanisms of mindfulness training on maternal cardiovascular parameters. Daily experiences will be measured using surveys delivered via smartphone-app, ambient audio sampling, and wearable wrist-worn biosensor monitoring (heart rate and heart rate variability).
