Is diabetes levelling off?

A decrease in obesity could be responsible for a plateau in the incidence of diabetes in the US.

In the US it looks like it might be – although not if you are Hispanic or an African American.

Incidence of diabetes more than doubled from 1990-2008, but since then seems to have plateaued for the general population, according to a report in the Journal of the American Medical Association.

Linda S. Geiss of the Centers for Disease Control and Prevention, Atlanta, and colleagues analysed 1980-2012 data for 664,969 adults ages 20 to 79 years to find the annual percentage change in rates of the prevalence and incidence of diagnosed diabetes – type 1 and type 2 combined.

The researchers speculate that reasons for the potential slowing of the increase in diabetes may include a slowing in the rate of obesity, a major risk factor for type 2 diabetes.

However, diagnosed cases kept rising in Hispanic and non-Hispanic black adults particularly those with a high school education or less.
