In findings that are likely to have serious implications for treatment-costs, adult incidence of diabetes rose 33 percent from 1990 to 1998, according to the U.S. Centers for Disease Control. Research published recently in Diabetes Care suggests an even more alarming rate of increase for Americans in their 30s — up 70 percent during the eight-year span.
Prevalence of diabetes in adults increased from 4.9 to 6.5 percent. If that's not worrisome enough, CDC officials warn that the trend probably hasn't peaked, thanks to higher rates of obesity. The prevalence of obesity has increased rapidly; 1 in 5 Americans was considered obese in 1998, up from 1 in 8 in 1991. Type 2 diabetes is a common consequence of obesity.
