Racial Disparities In Cardiovascular Health Linked To Birth Weight, Slavery

http://www.sciencedaily.com/releases/2008/10/081016124335.htm
ScienceDaily (Oct. 17, 2008) — Two new articles examine the theory of "fetal programming" and their effect on racial health disparities. The studies, published in American Journal of Human Biology, suggest that the higher rates of hypertension and cardiovascular disease present in African Americans may be a consequence of low birth weights, and that these low birth weights may be a result of social rather than genetic factors.

It is well-established that the nutritional and psychological state of a pregnant mother can influence whether her child will later develop cardiovascular disease as an adult. Nutrients and hormones present in the womb shape a fetus's development, in part by silencing certain genes in the body. These influences can persist into later life to impact adult health. Researchers from Northwestern University argue that such intergenerational impacts of environmental factors could help explain black-white differences in cardiovascular health in the U.S.
