Bumping this up, Glenn. I found two articles that are very
interesting about that A1C.

New thoughts are emerging about identifying diabetes today in the older population. With the baby boomers flooding our age group now, doctors are looking at new criteria in diagnosing type II diabetes in older patients.

As you can see in these two papers, fasting glucose, and GTT (2 hr probably) are being dropped in favor of A1C.

They are suggesting for older people that the cut off be 6.5.

I am printing these out for my doctor. The main reason I believe is that keeping blood sugar reading too low in the elderly is dangerous. The Accord study showed that the aggressive arm was not safe. Low blood sugars are showing high risk for Alzheimer's disease as well. So medicating or over medicating elderly patients may lead to more LOWs and hence affect brain functions.

I think you and I are in this boat. I am older than you, but have similar A1C readings presently. So at this time don't panic yet about your reading. It may just be a part of getting older.
