Clinical Trial Summary

The proposed study aims to evaluate if improving sleep could enhance the intensive lifestyle intervention for improving weight loss and glycemic control in prediabetic individuals who have insomnia with short sleep duration. A cognitive behavioral intervention for insomnia with adjustments aimed at increasing sleep duration (CBT-Sleep) will be used for this study.

Intervention

Behavioral:
• Intensive Lifestyle Intervention
This intervention is an abbreviated version of the Diabetes Prevention Program, which has been shown to be effective in reducing the risk of developing type 2 diabetes.
• Intensive Lifestyle Intervention enhanced with Cognitive Behavioral Sleep Intervention
This intervention will consist of the same 8 sessions of ILI with additions of sleep components in each session. The additional sleep components will include (a) psychoeducation about the importance of sleep in weight control and glycemic control, (b) sleep hygiene, (c) stimulus control, (d) modifying maladaptive beliefs about sleep, (e) and, setting individualized sleep schedule and reviewing sleep schedule.
