Brief 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.

Study Arms (2)
Intensive Lifestyle Intervention (ILI)
ACTIVE COMPARATORThe ILI will consist of 8 group-based 90-min sessions focusing on modifying dietary and exercise habits with the goal of reducing 450kcal of daily calories and increasing physical activity to 150 minutes of exercise per week.
ILI enhanced with cognitive behavioral sleep intervention
EXPERIMENTALThe ILI+Sleep intervention will consist of the same 8 sessions of ILI with additions of sleep components in each session.
Interventions
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.
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.
Eligibility Criteria
You may qualify if:
- (a) Hong Kong residents,
- (b) BMI \> 23kg/m2,
- (c) aged 18 to 65 year-old,
- (d) have prediabetes, defined by a plasma fasting glucose concentration of 5.6 to 6.9 mmol/L, impaired glucose tolerance (2hglucose 7.8-11.0 on OGTT), or HbA1c 5.7-6.4%,
- (e) have average habitual sleep duration \< 6.5 hours, confirmed by actigraphy measure of sleep for 2 weeks or have insomnia, confirmed in a clinical sleep interview and actigraph-measure of greater than 30 minutes of sleep onset latency or nighttime awakening for 3 nights or more per week
You may not qualify if:
- (a) have unmanaged sleep apnea or other sleep disorders,
- (b) have any current severe mental illnesses,
- (c) have any medical conditions or medication use that could undermine the efficacy of the sleep intervention,
- (d) have shift work schedules,
- (e) have any environmental constraints on the feasibility of implementing a sleep schedule of at least 7.5 hours
