Death rates among people with diabetes have declined substantially in recent years, according to a survey conducted by researchers at the Centers for Disease Control and Prevention and the National Institutes of Health.
Since 1997 the C.D.C. has done five surveys of people with and without diabetes, each sampling about 107,000 adults. Compared with the 1997-98 figures, 2006 death rates from cardiovascular disease had declined 40 percent and all-cause mortality had declined 23 percent among people with diabetes, even after the researchers controlled for age and other health factors. Death rates also declined among those who did not have diabetes, but the decline was not as steep.
The study, in the June issue of Diabetes Care, attributes the progress to advances in medical care and self-management.
