Dementia rates can vary significantly among Americans of different racial and ethnic groups, even if they're in the same region of the country, a new study finds.

Race and diseases   Researchers analyzed data on more than 274,000 people
Researchers analyzed data on more than 274,000 people from six racial and ethnic groups in Northern California who were members of Kaiser Permanente, a large private health care system.

Using records of patient visits, the researchers found that the average annual rate of dementia was 26.6 cases per 1,000 for blacks; 22.2 per 1,000 for American Indians/Alaskan Natives; 19.6 per 1,000 for Hispanics and Pacific Islanders; 19.3 per 1,000 for whites; and 15.2 cases per 1,000 for Asian-Americans.

The researchers calculated that among people who reach age 65 without dementia, 38 percent of blacks, 35 percent of American Indians/Alaskan Natives, 32 percent of Hispanics, 30 percent of whites, 28 percent of Asian-Americans and 25 percent of Pacific Islanders would develop dementia in the next 25 years.
