Study Shows that Diabetes Might Affect Half of Women with Sleep Apnea

A new study in the Journal of Clinical Sleep Medicine examined the influence of gender and obstructive sleep apnea (OSA) on the development of diabetes.

Past research indicates that low sleep duration can impair insulin metabolism – indicating that sleep loss, as experienced with OSA, might contribute to diabetes.

The study included 261 middle-aged subjects. None of them had diabetes in 1991. The researchers determined how many had diabetes 16 years later.

Subjects were asked to complete a postal questionnaire – 168 patients participated. They reported features such as height, weight, and OSA status. Participants also noted if a doctor had diagnosed them with diabetes.

A quarter of people with OSA developed diabetes. In contrast, 10.8 percent of people without OSA got diabetes. Increased risk varied between men and women.

Diabetes affected 19 percent of men with OSA verses 11 percent of men without OSA.

Women showed the biggest difference. Half of women with OSA got diabetes. Less than 10 percent of women without OSA had the condition.

In men, body mass index (BMI) predicted OSA presence. The association between OSA and diabetes was independent of age and BMI in women.

Results indicate that women with OSA have a high risk of developing diabetes.
