About

Women with a history of gestational diabetes (GDM) are at high risk of developing diabetes in the future. Sleep disturbances are emerging as risk factors for incident diabetes. The purpose of this study is to test the effects of 6-week sleep extension in women with a history of GDM and short sleep on glucose metabolism by randomized controlled study.

Full description

The primary aim of this study is to evaluate the effects of a sleep extension intervention in non-diabetic women with a prior history of GDM and habitual short sleep duration on the outcomes of glucose metabolism. The participants will be randomized to a 6-week sleep extension intervention group, using technology-assisted sleep intervention, or a healthy living information control group. Glucose metabolism parameters will be assessed by an oral glucose tolerant test.
