Brief Summary:
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.

Condition or disease Intervention/treatment Phase
Gestational Diabetes Behavioral: Sleep extension Behavioral: Healthy living Not Applicable

Detailed 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.

Arm Intervention/treatment
Experimental: Sleep intervention
Sleep extension
Behavioral: Sleep extension
Sleep extension aims to increase sleep duration for at least 30 minutes using weekly coaching

Active Comparator: Healthy living
Health education
Behavioral: Healthy living
Participants will receive weekly health education

Primary Outcome Measures :
  1. Changes in Glucose metabolism parameters [ Time Frame: 6 weeks ]
    Changes in serum glucose and insulin levels from oral glucose tolerant test (at 0,30,60,90 and 120 minutes) between baseline and 6 weeks

  2. Sleep duration [ Time Frame: 6 weeks ]
    Changes in sleep duration from baseline to 6 weeks

Secondary Outcome Measures :
  1. Glucose metabolism post intervention [ Time Frame: 10 weeks (4 weeks post intervention) ]
    Fasting glucose and insulin

  2. Energy metabolism post intervention [ Time Frame: 10 weeks (4 weeks post intervention) ]
    Weight and caloric intake

  3. Subjective sleep quality [ Time Frame: Baseline, week 6 and week 10 ]
    Pittsburgh sleep quality index (range 0 to 21 with higher score reflecting worse sleep quality)

  4. Energy metabolism [ Time Frame: 6 weeks ]
    Changes in weight, caloric intake, appetite, energy metabolism from baseline to 6 weeks

  5. Depressive symptoms [ Time Frame: Baseline, week 6 and week 10 ]
    Center for Epidemiologic Studies Depression Scale (range 0-60 with higher score reflecting more depressive symptoms)
