This clinical trial will determine if our updated insomnia treatment, called the SHADES intervention, improves CVD factors thought to explain how insomnia promotes CVD and if these improvements are due to positive changes in sleep factors. A total of 200 primary care patients with insomnia and CVD risk factors will be randomized to 6 months of the SHADES intervention (internet, telephonic, and\u002For face-to-face cognitive-behavioral therapy for insomnia) or the active control condition (sleep education\u002Fhygiene, symptom monitoring, and primary care for insomnia). Before and after treatment, participants will complete measurements of the CVD factors (systemic inflammation, autonomic dysfunction, metabolic dysregulation, proinflammatory gene expression) and the sleep factors (insomnia symptoms, sleep onset latency, wake after sleep onset, sleep efficiency). Researchers will test whether the SHADES intervention produces greater improvements in the CVD factors than the active control condition.","Cardiovascular disease (CVD) affects nearly 1 in 2 U.S. adults, is the #1 killer of men and women, burdens disadvantaged groups, and has costs greater than any other condition. While these statistics highlight the importance of CVD prevention, current approaches have only partial effectiveness. This has created a need to identify new CVD prevention targets, their underlying mechanisms, and effective interventions. Insomnia, its candidate mechanisms, and insomnia treatment are strong candidates in this regard. Thirty years of evidence indicates that insomnia is an independent, clinically important, robust, and potentially causal and modifiable risk factor for CVD. In addition, biologically plausible mechanisms that could explain how insomnia promotes the development of CVD have been proposed, with the most strongly supported being systemic inflammation, autonomic dysfunction, and metabolic dysregulation. Because insomnia now receives limited attention in settings where CVD prevention occurs (e.g., primary care), there is a large cohort of patients with an unaddressed CVD risk factor (insomnia). This status quo and the strong state of the insomnia-to-CVD science create the current need for a well-powered, mechanistic trial to elucidate biological mechanisms underlying the insomnia-to-CVD relationship and the mechanisms of action of cognitive-behavioral therapy for insomnia (CBT-I), both of which are presently unknown. Therefore, we are conducting a mechanistic trial of 200 primary care patients (45% minority) with insomnia and CVD risk factors but no clinical CVD. Participants will be randomized to 6 months of the SHADES (Strengthening Hearts by Addressing DisruptEd Sleep) intervention or the active control condition. The SHADES intervention is our modernized collaborative care intervention consisting of well-established internet, telephonic, and\u002For face-to-face CBT-I. The active control condition consists of sleep education\u002Fhygiene, symptom monitoring, and primary care for insomnia. Our proposal has four aims - Aim 1: determine the effect of the SHADES intervention on our primary CVD mechanism of high-sensitivity CRP; Aim 2: determine the effect of the SHADES intervention on our secondary CVD mechanisms of systemic inflammation, autonomic dysfunction, and metabolic dysregulation; Aim 3: examine if 6-month improvements in upstream sleep mechanisms mediate the SHADES intervention effect on 6-month improvements in downstream CVD mechanisms; Exploratory Aim: explore the effect of the SHADES intervention on proinflammatory gene expression. This trial could generate the critical support for the mechanistic rationale and conceptual framework needed to justify the next-step phase III, multi-site clinical trial to determine the SHADES Intervention effect on CVD clinical outcomes, endpoints of great public health relevance, morbidity, and cost.",[19,20,21,22,23,24,25,26,27,28,29,30],"Insomnia","Insomnia Chronic","Insomnia, Primary","Sleep Disturbance","Sleep Disorder","Cardiovascular Diseases","Heart Diseases","Coronary Artery Disease","Stroke","Autonomic Dysfunction","Systemic Inflammatory Response","Metabolic Disease",[32,33,34,19,24],"Primary Care","Internet Interventions","Cognitive-Behavioral Therapy for Insomnia","INTERVENTIONAL","PREVENTION",[38],"NA",{"count":40,"type":41},200,"ESTIMATED",[43,49,53,57],{"type":44,"name":45,"description":46,"armGroupLabels":47},"BEHAVIORAL","Sleep Healthy Using The Internet (SHUTi)","Sleep Healthy Using The Internet (SHUTi) is an empirically supported internet intervention.
