A study (#0866) being presented later this morning as a poster indicates that insomnia with short sleep duration is associated with an increased risk of diabetes. Yesterday the same research team presented an abstract (#0868) showing that chronic insomnia with objective short sleep duration in men also is associated with an increased risk for mortality.
In the April 1 issue of the journal SLEEP, the researchers also published a study showing that chronic insomnia with objectively measured short sleep time is an independent and clinically significant risk factor for hypertension. Read an AASM press release about the study.
According to the authors, these results indicate that objective sleep duration may predict the medical severity of chronic insomnia, and they suggest that the medical impact of insomnia has been previously underestimated.
