The intervention administered to participants is an incentive program designed to motivate participants to attend to/adhere to their prescribed prenatal course of care via the Aqueduct platform.

All individuals who consent to participate will engage with the Aqueduct contingency management system. Once participants are enrolled, they accumulate points in Aqueduct for each prenatal/postpartum appointment they attend. They also earn points for attending pregnancy and birth related classes, monitoring their health (e.g., blood sugar, blood pressure), and taking prescribed medications. Participants then redeem their points for money on a Visa gift card.

Enrolled participants also receive daily text messages that contain motivational and mini-educational content regarding pregnancy from trusted sources such as the American College of Obstetricians and Gynecologists, Evidence Based Birth, and Postpartum Support International. These texts serve as reminders to participants to remain engaged in their pregnancy care.

Using data from Mt. Sinai's electronic medical record appointment tracking system, the investigators will determine whether participants who received the Aqueduct system intervention demonstrate increased attendance at scheduled prenatal visits compared with baseline data in the clinic about attendance rates.

Using descriptive statistics from recruitment, the investigators will determine whether the percentage (%) of eligible individuals from the population of pregnant women in their third trimester receiving prenatal care at the Mt. Sinai E-Level OB Clinic who elected to participate in the study increases between Wave 1 and Wave 2 of recruitment based upon changes in recruitment language.

Using self-reported frequency of eating fruits, vegetables, and fried foods (measured as average number of days per week over the past month), the investigators will determine whether participants who received the Aqueduct system intervention demonstrate increased frequency in consumption of fruits and vegetables, as well as decreased fried food consumption, from baseline (start of third trimester) to follow-up (postpartum appointment ~6 weeks after giving birth).
