ABSTRACT
INTRODUCTION: Health disparities research has demonstrated a negative relationship between racial discrimination and African American women's maternal health outcomes. Yet, the relationship between racial discrimination and preterm labor, a key measure of maternal health, remains understudied. This study sought to examine the associations between preterm labor and direct and vicarious racial discrimination among African American women at three life stages: childhood, adolescence, and adulthood. METHODS: Logistic regression methods were used to analyze cross-sectional data from the African American Women's Heart & Health Study (AAWHHS; N = 173). The AAWHHS includes detailed maternal health information on a community sample of African American women residing in the San Francisco Bay Area. RESULTS: Findings indicated each unit increase in adolescent direct racial discrimination was associated with a 48% increase in the odds of preterm labor (OR: 1.480, 95% CI 1.002-2.187, p < 0.05) and each unit increase in childhood vicarious racial discrimination was associated with a 45% increase in the odds of preterm labor (OR: 1.453, 95% CI 1.010-2.092, p < 0.05) after adjusting for number of pregnancies and socioeconomic variables. DISCUSSION: This study provides evidence of an association between life-stage racial discrimination and preterm labor risk among African American women, underscoring a need to consider how both directly and vicariously experienced racial discrimination at different developmental periods impact racial disparities in birth outcomes.
