Half U.S. Adults Have Diabetes or Pre-Diabetes In 2011-2012, the estimated prevalence of diabetes among U.S. adults was 12 percent to 14 percent and the prevalence of pre-diabetes was 37 percent to 38 percent, indicating that about half of the U.S. adult population has either diabetes or pre-diabetes, according to a study in theåÊ JAMA. Diabetes is a major cause of illness and death in the United States, costing an estimated $245 billion in 2012 due to increased use of health resources and lost productivity. Researchers included data from surveys conducted between 1988-1994 and 1999-2012; 2,781 adults from 2011-2012 were used to estimate recent prevalence and an additional 23,634 adults from 1988-2010 were used to estimate trends. In the overall 2011-2012 population, prevalence was 14.3 percent for total diabetes, 9.1 percent for diagnosed diabetes, 5.2 percent for undiagnosed diabetes, and 38 percent for pre-diabetes; among those with diabetes, 36.4 percent were undiagnosed. The prevalence of total diabetes was higher among non-Hispanic black participants (21.8 percent), non-Hispanic Asian participants (20.6 percent), and Hispanic participants (22.6 percent). The prevalence of pre-diabetes was greater than 30 percent in all sex and racial/ethnic categories, and generally highest among non-Hispanic white individuals and non-Hispanic black individuals. The authors note that although there was an increase in diabetes prevalence between 1988- 1994 and 2011-2012, prevalence estimates changed little between 2007-2008 and 2011-2012. ÛÏThis plateauing of diabetes prevalence is consistent with obesity trends in the United States showing a leveling off around the same period.Û Of course all this said, the statistics are appalling. What is important to remember is that diabetes can be controlled and eliminated with diet and exercise. It is a lifestyle disease for the most part.
