Diabetes news: Extremely tight control increases risk of death in one population

Diabetes Study Partially Halted After Deaths by Gina Kolata.

Executive summary: Maintaining an A1C of 7 leads to a reduced risk of death compared to maintaining an A1C of 6 or less, for people averaging age 62 who have had diabetes about 10 years and are on meds and/or insulin.

For decades, researchers believed that if people with diabetes lowered their blood sugar to normal levels, they would no longer be at high risk of dying from heart disease. But a major federal study of more than 10,000 middle-aged and older people with Type 2 diabetes has found that lowering blood sugar actually increased their risk of death, researchers reported Wednesday.
Dr. John Buse, the vice-chairman of the study’s steering committee and the president of medicine and science at the American Diabetes Association, described what was required to get blood sugar levels low, as measured by a protein, hemoglobin A1C, which was supposed to be at 6 percent or less.

“Many were taking four or five shots of insulin a day,” he said. “Some were using insulin pumps. Some were monitoring their blood sugar seven or eight times a day.”

They also took pills to lower their blood sugar, in addition to the pills they took for other medical conditions and to lower their blood pressure and cholesterol. They also came to a medical clinic every two months and had frequent telephone conversations with clinic staff.

Those assigned to the less stringent blood sugar control, an A1C level of 7.0 to 7.9 percent, had an easier time of it. They measured their blood sugar once or twice a day, went to the clinic every four months and took fewer drugs or lower doses.
the drug Avandia, suspected of increasing the risk of heart attacks in diabetes, did not appear to contribute to the increased death rate.
I am on a fat-accepting diabetes list (which seems to be down at the moment) where a lot of people are into very tight control, keeping their A1C in the 5-6 range. I tend to argue for a more relaxed approach, and I keep my A1C in the 6-7 range. I'm relieved to find evidence that my approach has some validity for one population.
