E. African Americans at Higher Risk of Diabetes

Narrator: This is Science Today. Over the past two decades, the prevalence of diabetes in the nation's African American population has gone up 33 percent. University of California, Davis nutrition specialist, Lucia Kaiser recently helped conduct a California-based diabetes awareness study and says one of the problems is a lack of information about the disease in African American populations.

Kaiser: One of the things they said was there's a lot of information about other diseases, but given the fact that they're at high risk for diabetes, there's relatively little little information that was coming from the doctor's offices. In fact, there was confusion about whether they were being screened at all.

Narrator: Kaiser says one of the key factors for the high rate of diabetes is obesity and lack of exercise.

Kaiser: It's both genetic factors, as well as lifestyle that has changed in the last century that's causing a problem in this population - but not only in African Americans, but in the population as a whole in the United States because diabetes is on the rise among all groups.
