By CDC, U.S.,
Edward Gregg, Ph.D., of CDC�s diabetes program and his CDC co-authors, analyzed NHANES data and found large decreases in many of the cardiovascular disease risk factors known to be associated with early deaths in all U.S. adults ages 20-74, regardless of their BMI. The exception was diabetes. The prevalence of total (diagnosed and undiagnosed) diabetes increased by 55 percent over the past 40 years, likely the result of the dramatic increase in obesity during this time period.
Other key findings:
* Prevalence of elevated cholesterol and blood pressure dropped by almost half in all U.S. adults ages 20-74, while smoking prevalence dropped by about a third.
* Reductions in the prevalence of high cholesterol levels were most substantial among obese people compared to lean individuals.
* Reductions in blood pressure and smoking prevalence were similar among lean and obese persons.
