Official title

Quantitative Activity Levels and Gestational Age at Delivery: A Prospective Cohort Study Among Nulliparous Women

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Almost half of all deliveries in the United States are of nulliparous patients. They have been identified as an at-risk population for preterm birth. Historically, the most significant risk factor for preterm birth is a prior history of preterm birth, which cannot be applied to a nulliparous population. Forecasting adverse outcomes in first time moms is difficult to predict and prevent. Historically, physicians have prescribed a restriction in activity level for those at risk for preterm delivery. The utility of this intervention has yet to be prospectively and quantitatively studied. The Fitbit activity tracker is a wearable device that has been extensively used in medical research, in an attempt to quantitatively identify how patient activity levels can improve medical outcomes. The study uses the Fitbit device in nulliparous patients, remotely track their activity levels throughout pregnancy, and assess pregnancy outcomes. Because of the significant and long-standing health disparity in the incidence of preterm delivery, the investigators will use the "Everyday Discrimination Scale", a validated battery of racism and health to see how a patient's stress related to perceived discrimination may modify the risk of preterm delivery.
