Mass Incarceration, Residential Segregation and Stillbirth Risks

Structural racism, the historical and systemic exclusion of racial and ethnic minorities (particularly African Americans) from access to opportunities and resources, may impact the social environment, reinforcing systems of discrimination, in criminal justice and housing, among others. For example, mass incarceration has a worsening effect on disadvantaged neighborhoods, through destabilizing the community and breaking up families and social networks. Such stressors have been recognized as the drivers for racial disparities in health outcomes in the general population as well as disparities in obstetric outcomes. While mass incarceration has been linked to adverse perinatal outcomes, no studies have examined the impact of criminal injustice on associations with stillbirth. Further, racial segregation, a legacy of discriminatory financial lending and housing practices, has also been associated with health disparities, including those related to adverse birth outcomes. Two recent investigations reported associations between segregation and race-specific rates of stillbirth using measures evaluated either at the county or zip code tabulation area (ZTCA) level) and our proposed study will apply finer resolution metrics in evaluating the impact of residential segregation on stillbirth risk.

Harris County is home to the third largest criminal justice system in the country and has one of the most diverse populations in the nation. Drawing on prior experience with birth records and fetal death certificates we will assemble a cohort of women in Harris County over a 14-year period who delivered a live birth or stillbirth to evaluate the impact of incarceration rates and racial segregation on Black-White disparities in stillbirth.

The Specific Aims of the study are:

Aim 1

Characterize census tract-level rates of mass incarceration and racial segregation in Harris County using individual-level jail and prison incarceration data and U.S. census data.

Aim 2

Evaluate whether there are racial differences in the impact of neighborhood-level incarceration rates on risk of stillbirth.

Aim 3

Evaluate the impact of racial segregation on Black-White disparities in stillbirth in Harris County.
