It has long been known that African Americans have a greater incidence of high blood pressure, compared with whites. Now a new study in the March 24, 2003, online issue of Hypertension reports that blacks are almost twice as likely to develop hypertensive retinopathy, a form of blood vessel damage in the eye.
The study included 1860 blacks and 7874 whites and found the rate of hypertensive retinopathy in blacks to be 7.7%, compared with 4.1% in whites. It is a significant finding because "Blood vessel damage in the eye is linked with similar changes in the brain and has been shown to be associated with a higher risk of stroke and death, independent of known risk factors," according to the study authors.
Although the annual HIV diagnosis rate between 2010 and 2014 decreased for black individuals by 16.2%, blacks remain disproportionately affected by HIV/AIDS.
