Eliminating disparities in perinatal outcomes--lessons learned.

The disparity between blacks and whites in perinatal health ranges from a 2.3-fold excess risk among black women for preterm delivery and infant mortality to a 4-fold excess risk among black women for maternal mortality. To stimulate concerted public health action to address such racial and ethnic disparities in health, the national Healthy People objectives call for elimination of all health disparities by the year 2010. Eliminating health disparities requires a greater understanding of the factors that contribute to their development. This commentary summarizes the state of the science of reducing such disparities and proposes a framework for using the results of qualitative studies on the social context of pregnancy to understand, study, and address disparities in infant mortality and preterm delivery. Understanding the social context of African American women's lives can lead to an improved understanding of the etiology of preterm birth, and can help identify promising new interventions to reduce racial and ethnic disparities in preterm delivery.
