According to an analysis of data on diabetes in the US shows that nearly 13% people aged 20 and above have diabetes and nearly 40% among them have not been diagnosed yet.

In a previous study, the rates of undiagnosed people were almost the same, but this study shows a larger proportion of diabetics than found in that previous study.

Catherine C. Cowie, the lead author of the study, says in this connection: “It can be said without any doubt that the cases of diagnosed diabetes have considerably increased that were 5.1% from 1988 to 1994 and were 7.7% from 2005 to 2006. It has been also observed that the cases of diagnosed diabetes have increased in African-Americans particularly.”

“While, the number of undiagnosed and pre-diabetes cases is still quite stable with 30% and it’s, indeed, a good news,” Catherine added. “If the cases of undiagnosed diabetes remain the same and diagnosed cases go up, it means we are doing a good job in detecting these cases.”
