Women with type 2 diabetes were prone to experience difficult sleeping, according to an analysis of data from more than 133,000 individuals who were part of the Nurses’ Health Study and NHSII.

Participants did not have diabetes, CV disease, or cancer at baseline. Among the results after up to 10 years of follow-up:

• There were ~6,400 cases of type 2 diabetes.

• After adjusting for lifestyle factors at baseline, women with sleeping difficulty were nearly 1.5 times more likely to have diabetes than those who did not have sleep issues.

• They were also 1.22 times more likely to have diabetes after investigators further adjusted for hypertension, depression, and BMI.

• Women in the NHS study who had difficulty sleeping, snored frequently, slept 6 hours or less, and had sleep apnea were more than 4 times more likely to have diabetes.

• The same was true for those in NHSII who worked in rotating shifts.
