Effects of Race and Ethnicity on Perinatal Outcomes in High-income and Upper-middle-income Countries: An Individual Participant Data Meta-analysis of 2,198,655 Pregnancies

Abstract

(Lancet. 2022;400:2049–2062) Health disparities and inequalities for pregnant patients effect short-term and long-term outcomes, potentially for generations. Existing studies on the effects of race and ethnicity for parturients have been country specific. This study aimed to investigate the effects of health disparities and inequalities globally from under-represented and underserved ethnic and racial groups, especially those in high- and upper-middle-income countries, and to determine how disparities vary geographically.
