With the right data in the right people’s hands, we hope to create a window of opportunity for change.

About our Policy Core

We believe that structural changes through policy action are an important way to create sustainable improvements in birth outcomes for women of color and specifically Black women. Our Policy Core was developed with this in mind and is comprised of a diverse network of researchers, parents, lactation consultants, doulas, nurses, doctors, community practitioners, public servants who are calling for change.

How can the PTBi-CA Policy Core contribute to policy?

1. Conduct policy-focused research
2. Partner with organizations in coalitions that are advocating for policy change
3. Educate policymakers about scientific evidence, generated within and outside of PTBi
4. Support policy efforts undertaken by the collective impact coalitions we support

By working with policymakers, we aim to spotlight the broken systems that limit access to essential resources for Black and Brown birthing communities to thrive. With the right data in the right people’s hands, we hope to create a window of opportunity for change.

Programs that Drive Policy Change

In addition to our policy research, we support coalitions that are driving policy change. In San Francisco, we are supporting Expecting Justice, and in Fresno, we are supporting Fresno Grows and the Black Maternal Wellness Lab.

Central to our work is community-based participatory research (CBPR) that allows us to identify priorities for policy change in communities that have been directly affected. In 2016, we launched the Benioff Community Innovator program in San Francisco who conducted research that led to the policy recommendation to prioritize homeless pregnant women for emergency housing support prior to their third trimester. In 2020, we launched our second cohort of Benioff Community Innovators in Oakland.

Housing Insecurity and Obstetric Racism

In 2020, we identified PTBi's top two policy priorities as housing insecurity and disrespectful care/obstetric racism. Based on these priorities, two policy projects were developed and submitted to the Goldman School of Public Policy at UC Berkeley. In 2021, two Masters of Public Policy students conducted studies on these projects. The first was to conduct an implementation analysis of SB-464, or the California Dignity in Pregnancy and Childbirth Act, to identify barriers, facilitators, and best practices for the policy implementation of implicit bias trainings. SB-464 is a bill that was intended to address the disparities in Black maternal health and birthing outcomes by focusing interventions on healthcare systems and providers. The second was examining the impact of evictions on preterm births and family health outcomes to provide insight into the experience of housing instability during pregnancy as well as policy solutions to address this problem.
