Why do Black, Latina and other racial and ethnic minority mothers and their babies still face worse health outcomes, from postpartum depression to preterm birth, and what could close that gap? Two projects tackle the question from different directions.

What they work on

  1. Develop the Rosie chatbot by building a large health information library and improving its natural language processing engine so it reliably understands the many ways new mothers phrase questions.
  2. Test in a randomized controlled trial, with mostly virtual recruitment, whether using Rosie lowers postpartum depression risk, reduces emergency room visits and increases well-baby visit attendance.
  3. Release an open-source package that lets other groups build their own health information chatbots.
  4. Track changes in area-level sentiment across the United States using machine learning models applied to online and social media data, and identify the local and national events tied to those changes.
  5. Determine whether shifts in area-level sentiment lead to changes in preterm birth and low birth weight, and identify protective factors that buffer these adverse birth outcomes.

More about the research

One builds and tests a chatbot that gives new mothers trustworthy health answers at the moment they need them. The other uses online and social media data to ask whether the mood of a community affects birth outcomes. Both combine epidemiology, the study of health patterns in populations, with computer science and machine learning.

Why it matters

Racial and ethnic minority mothers and infants face higher rates of postpartum depression, missed well-child checkups, preterm birth, low birth weight and death. A scalable chatbot could give these families fast, verified health information without costly home visits and protect them from web misinformation. Measures of community sentiment and protective factors could help public health agencies design population-level policies to reduce these disparities.
