Diabetes is expected to grow by 200 percent in the U.S. over the next 40 years, with Latinos seeing the fastest growing rate of any racial or ethnic group. 

A new report from Temple University suggests that Latinos are most affected because of acculturation, or the process of adopting the behaviors, attitudes and values of a different culture. 

The study says more than 20 percent of Mexican-American adults, the largest subgroup of U.S. Latinos, have diabetes. That's compared to 11 percent for non-Hispanic whites and nearly 19 percent for non-Hispanic blacks. 

According to the Centers for Disease Control and Prevention, risk factors for diabetes include being overweight or obese, having a relative with diabetes, high blood pressure and abnormal cholesterol, and being physically inactive.
