Iowa Researcher Finds Disparities in Birth Weight and Gestational Age by Ethnic Ancestry in South American Countries

University of Iowa associate professor of health management and policy, Dr. George Wehby, and a team of researchers recently released the results of their study examining the disparities in birth weight and gestational age by ethnic ancestry in South American countries. The study, published in the December 2014 issue of the International Journal of Public Health, found significant disparities in seven countries – Brazil, Ecuador, Uruguay, Venezuela, Argentina, Bolivia, and Colombia – and the differences across countries suggest that racial/ethnic disparities are driven by social and economic mechanisms.


“To the best of our knowledge, ours is the first study to evaluate ethnic disparities in infant health across many South American countries using the same data source and analytical model,” says Dr. Wehby. “Accurate assessment of these differences is an important first step for explaining ethnic disparities in infant and child health in these countries and devising cost-effective interventions to eliminate them.”
