Researchers from Brown University and the Jackson Heart Study say that physicians should be aware of new findings about a blood test used to monitor diabetes. The results could mean missed chances to treat diabetes in African-Americans with a common genetic trait.
University of Mississippi Medical Center scientists co-authored the study, published Feb. 7 in the Journal of the American Medical Association. The results show that in people with the same fasting glucose level, sickle cell trait is associated with a lower than expected hemoglobin A1C, or HbA1c.
Diabetes is an important and prevalent risk factor in the Jackson Heart Study, said Dr. Adolfo Correa, UMMC professor of medicine, JHS director and co-author of the paper.
“If not controlled, diabetes over time will result in damage to the heart, kidneys and eyes, as well as cause unhealthy levels of cholesterol and blood lipids, high blood pressure and reduced cardiovascular health,” he said.
The JHS is a collaboration between UMMC, Jackson State University and Tougaloo College. It is the largest study of African-American cardiovascular health, following 5,300 community members since 2000.
This recent paper studied 4,620 people from the JHS and the Coronary Artery Risk Development in Young Adults study, or CARDIA, with similar fasting and two-hour blood glucose levels.Continue Reading...
