Women with singleton births in 2011-2017 (n = 6199) were included. Risk and protective factors for PTB and independent risk groups were identified using logistic regression and recursive partitioning. Having less than 3 prenatal care visits was associated with highest PTB risk. Hypertension (preexisting, gestational), previous PTB, and unknown Women, Infant, Children (WIC) program participation were associated with a two-fold increased risk for PTB. Maternal birth outside of the USA and participation in WIC were protective. Broad differences in rates, risks, and protective factors for PTB were observed.Journal of racial and ethnic health disparitiesRisk and Protective Factors for Preterm Birth Among Black Women in Oakland, California.PMC8079235N/AK12 HD052163Oltman SPRand LBaer RJBerkowitz RLScott KJelliffe-Pawlowski LLMcKenzie-Sampson SKuppermann MMelbourne DFranck LFuchs JTaylor BKarasek DAChambers BDWilliams SMcLemore MRfalseRisk and Protective Factors for Preterm Birth Among Black Women in Oakland, California.This project examines risk and protective factors for preterm birth (PTB) among Black women in Oakland, California.
