Thirty years ago, the U.S. Centers for Disease Control and Prevention (CDC) held a truly pathbreaking 3-day symposium, by invitation only, that explicitly focused on racism, sexism, social class, and health.1 Titled “Preterm delivery among Black women: The symposium on psychosocial factors” (December 2–5, 1991), this meeting was organized by a visionary group of African American women researchers, led by Diane Rowley, who were based in the Pregnancy and Infant Health Branch in the Division of Reproductive Health in CDC's National Center for Chronic Disease Prevention and Health Promotion (Table 1).
