Incidence of T2DM Rising in Fewer Populations Since 2006

Incidence rising in 33 percent of populations versus increase in 66 percent of populations in 1990 to 2005

THURSDAY, Sept. 12, 2019 (HealthDay News) -- Since 2006, the incidence of type 2 diabetes has continued to rise in a minority of populations, with decreasing incidence in more than one-third of populations, according to a review published online Sept. 11 in The BMJ.

Dianna J. Magliano, Ph.D., from the Baker Heart and Diabetes Institute in Melbourne, Australia, and colleagues conducted a systematic review of studies reporting trends in diabetes incidence in adults from 1980 to 2017. Data were included from 47 studies with 121 separate sex-specific or ethnicity-specific populations; 89 percent of the studies reported on diagnosed diabetes.

The researchers found that from 1960 to 1989, 36, 55, and 9 percent of the 22 populations studied had increasing trends, stable trends, and decreasing trends in diabetes incidence, respectively. In 1990 to 2005, diabetes incidence increased, was stable, and decreased in 66, 32, and 2 percent of 50 populations studied, respectively. In 2006 to 2014, 33, 30, and 36 percent of 33 populations had increasing trends, stable incidence, and declining incidence, respectively.

"In most countries for which data are available, the incidence of diagnosed diabetes was rising from the 1990s to the mid-2000s, but has been stable or falling since," the authors write. "Preventive strategies and public health education and awareness campaigns could have contributed to this recent trend."
