Should Race Be Used as a Variable in Research on Preterm Birth?

Racial variations in preterm birth (PTB) outcomes are well described, but causal mechanisms linking race and PTB are not. In clinical research, race is typically treated as representing fixed biological traits. In reality, race is a social construct that approximates lived experiences of historical and ongoing systematic discrimination and, in the case of PTB, particular stressors of black womanhood and reproduction. These experiences are embodied as adverse multigenerational health outcomes. Race thus presents a dilemma for researchers. Conflating race with genetics enacts harm, but excluding the race variable produces irrelevant research. Instead, we must consider race in an ecosocial context. PTB is fertile ground for expanding research approaches to respect the history, reality, and implications of race in the United States.
