National Diabetes Awareness Month --- November 2006

In 2005, an estimated 20.8 million persons in the United States (approximately 7% of the population) had diabetes; however, only 14.6 million of these persons had received a diagnosis for their disease (1). According to current projections, by 2050, approximately 48 million persons in the United States will have diabetes diagnosed, nearly 9 million more persons than previously estimated for 2050 (2). In 2002, approximately 54 million adults in the United States had prediabetes (i.e., blood glucose levels higher than normal but not high enough to be classified as diabetes) (1). Obesity is a major factor, although not the sole factor, in the increased rate of newly diagnosed cases of diabetes. Lifestyle changes such as moderate weight loss and exercise can prevent or delay onset of type 2 diabetes among adults at high risk (3). Information on how to prevent and control diabetes is available at and

November is National Diabetes Awareness Month. Throughout the month, MMWR will publish reports on diabetes and its complications in specific populations. This week's issue describes the first nationally representative study to estimate the proportion of U.S. adults with diabetes who have correctable visual impairments.
