Insomnia symptoms are linked to metabolic syndrome (MetS), which includes abnormal glucose metabolism, insulin resistance (IR), and incidence of diabetes. Chronic sleep deficit is a major predictor of disease and early mortality. Further, insomnia is the most common sleep disorder in the United States. The recommended first line of treatment for insomnia is Cognitive Behavioral Therapy for Insomnia (CBT-I). CBT-I is a multidimensional treatment that targets the thoughts and behaviors that perpetuate insomnia symptoms over time. This study will explore CBT-I effects on MetS outcomes (ie. blood pressure, triglycerides, etc.) and provide preliminary evidence that CBT-I impacts IR and fasting glucose concentrations within this population. 20 subjects with insomnia will be recruited. They will be randomly assigned to either CBT-i or sleep hygiene. The intervention is 5 wks. Pre and post intervention, the investigator will have participants fill out a number of questionnaires, a daily sleep diary, 2 weeks of actigraphy measuring sleep and physical activity and there will be a single blood draw at the beginning and the end of the study.
Insomnia symptoms are linked to metabolic syndrome (MetS), which includes abnormal glucose metabolism, insulin resistance (IR), and incidence of diabetes. In young healthy individuals, shortened sleep duration results in IR and elevated free fatty acid concentrations and has been associated with circadian misalignment. Additionally, individuals with type 2 diabetes (T2D) frequently have insufficient sleep or poor sleep quality, and greater sleep disturbances are associated with poorer glycemic control. Thus chronic sleep deficit is a major predictor of disease and early mortality. Further, ins…
