Contrary to earlier reports, a new study from the Journal of the American Medical Association has reported that Caucasians with diabetes are more likely than other ethnic groups (blacks, Asians and Latinos) to have a heart attack.

Earlier studies that included patients from all groups, both insured and uninsured, have reported higher rates of complications in blacks, Hispanics and other minority groups. This study differs in that it was done among 62,000 patients of Kaiser Permanente, so all of them had equal access to care.

Other findings:

• Caucasians and blacks had a greater risk of developing stroke or congestive heart failure than Asians and Latinos.
• The risk of stroke and heart failure for Caucasians and blacks was similar.
• Caucasians were less likely to develop kidney failure than other ethnic groups.
• Asians were least likely to require amputations.

Because minorities develop type 2 diabetes at a higher rate than do whites, a larger number of members of ethnic groups are at risk overall.

The investigators suggest that the differences may be due to genetics or to some unmeasured environmental factors. Their report can help people with diabetes to be particularly diligent in seeking screening or taking action to prevent specific complications, depending on their ethnicity. People with diabetes can help themselves be making sure they are screened for early complications, which can often be treated effectively. Studies like this one can also provide clues that lead scientists to better understand the genetic factors that contribute to complications.
