Objective: Interpersonal discrimination has been associated with adverse birth outcomes among Black populations, but few studies have examined the impact of discrimination among Latinx/Hispanic populations in the United States, especially in conjunction with resources that could be protective. The present study examined (a) if exposure to discrimination is associated with adverse birth outcomes for Latina/Hispanic women and (b) if prenatal social support buffers these links. Method: In two independent prospective studies of Latina/Hispanic women in Southern California (N = 84 and N = 102), the relation between maternal experience of discrimination and birth outcomes (length of gestation and birth weight) was examined. Additionally, social support was tested as a moderator of these relations. Results: In both Studies 1 and 2, exposures to discrimination predicted adverse birth outcomes. Specifically, lifetime experiences of major discrimination predicted lower birth weight. Additionally, in Study 2, chronic experiences of everyday discrimination were linked to lower birth weight. In Study 1, major discrimination also predicted shorter gestational length. Importantly, in both studies, the presence of prenatal social support buffered associations between discrimination and poorer birth outcomes. Conclusions: Findings implicate discrimination as an important risk factor for adverse birth outcomes among women of Latina/Hispanic descent. Further policies, practice, and research on reducing discrimination and enhancing factors that promote resilience such as social support are needed to facilitate healthy births among Latina/Hispanic women, mitigate intergenerational harm of discrimination-related stress, and advance health equity at birth and across the lifespan.
