FRIDAY, May 6 (HealthDay News) — People with diabetes who sleep
poorly have higher blood glucose levels and a more difficult time
controlling their disease, a new study shows.
Researchers compared 40 people with type 2 diabetes to 531 people
without the blood sugar disease. The investigators looked at potential
links between sleep quality, blood glucose levels and other measures of
diabetes control.
“We found that in those with diabetes, there was an association between
poor sleep quality and worse glucose measures,” said study leader Kristen
Knutson, an assistant professor of medicine at the University of
Chicago.
“We did not see a relationship in people without diabetes,” she
said.
The study is published in the May issue of Diabetes Care.
Previous research has found some linkage between diabetes and poor
sleep. Knutson said it is just an association, not cause-and-effect. “It
may be that people with diabetes are more vulnerable to the effects of
impaired sleep,” she said. “But it could go either way.” Those who don’t
control their diabetes could have worse sleep than those who do, she

“We need to look more closely at the role of sleep in diabetes,” she
added.
For the study, Knutson monitored sleep by having people wear wrist
