Why 7 Deadly Diseases Strike Blacks Most
Health care disparities heighten disease differences between African-Americans and white Americans.

Clinical trials show blacks and whites respond differently to treatments for high blood pressure. Indeed, treatment guidelines suggest that doctors should consider different drugs based on a patient's race.
But Yancey says that a closer look at the data shows that race tends to be a marker for more complicated high blood pressure treatment.
"Data suggests that all therapies do equally well -- but patients at higher risk need more intensive therapy," he says.
A similar situation exists for heart failure. A promising treatment for heart failure didn't seem to be working -- until researchers noticed that it worked much better for black patients than for white patients. A study of black patients confirmed this finding -- and provided tantalizing evidence that the drug will help patients of all races with certain disease characteristics.
"The way this discussion of race differences has been helpful for the whole field of cardiology, is it is exposing new treatment options for all people with heart failure, African-American and Caucasian," Yancy says.
Black Americans and Diabetes
Black Americans -- and Mexican-Americans -- have twice the risk of diabetes as white Americans. In addition, blacks with diabetes have more serious complications -- such as loss of vision, loss of limbs, and kidney failure -- than whites, notes Maudene Nelson, RD, certified diabetes educator at Naomi Barry Diabetes Center at Columbia University.
"The theory is that maybe it is access to health care, or maybe a cultural fatalism -- thinking, 'It is God's will,' or, 'My family had it so I have it' -- not a sense of something I can have an impact on so it won't hurt me," Nelson tells WebMD. "But more and more there is thinking it is something that makes blacks genetically more susceptible. It is hard to tell how much of it is what."
The Forgotten Killer
There is, indeed, evidence that African-Americans may have a genetic susceptibility to diabetes. Even so, Nelson says, the real problem is empowering patients to keep their diabetes under control.
"Patients often have the sense that they are not as much in charge of managing their diabetes as their doctor," Nelson says. "Where I work, in various settings, there is an emphasis on patients. We say this is what your blood sugar is; this is what influences your blood sugar; you have to remember to take your meds. So as a diabetes educator I know there has to be an emphasis on patients putting out more effort to manage their own health."
