About the research
Our accumulating evidence indicates that young adults that have been exposed to Adverse Childhood Experiences (ACEs) display both impaired vascular function, poorer cardiometabolic health, and poor sleep. Our data indicate that sleep impairments may mediate the link between ACEs and vascular and metabolic dysfunction. The primary purpose of this project is to determine if cognitive behavioral therapy for insomnia (CBT-i) is feasible for improving sleep in young adults who have been exposed to ACEs and who have poor sleep. Secondarily, we will collect preliminary efficacy data to determine whether CBT-i can improve vascular and cardiometabolic health in this population, as well as perceived stress and anxiety.
Read the full description
Sleep disruption is an important, emerging risk factor for CMD morbidity and mortality \[9\], and is associated with leading cardiometabolic risk factors such as hypertension, insulin resistance, and obesity \[1,2\]. It is likely that poor sleep increases CMD-related risk by promoting circadian disruption \[3\]. A growing body of evidence suggests that ACEs are associated with disturbed sleep. Indeed, strong preliminary evidence from our laboratory indicates that young adults with a history of ACEs self-report poor sleep and present with altered diurnal cortisol concentrations indicative of disrupted circadian variation \[4\]. Accordingly, our hypothesis is that sleep disruption is a hallmark, stress-related symptom of ACEs, and therefore that sleep disruption is a modifiable, mechanistic pathway by which ACEs promote CMD risk. Accordingly, building on our initial data indicating that poor sleep mediates the association between ACE exposure and vascular and metabolic dysfunction, our overall objective in this pilot project is to first (1) test the first line treatment to improve sleep among those suffering from insomnia (CBT-i) for improving sleep in individuals with high ACEs and sleep disruption and (2) explore whether this intervention promotes positive effects on vascular and metabolic health, as well as psychological coping, stress, and anxiety/depression symptoms.

CBT-I
Participants will undergo a CBT-i intervention delivered by clinical psychologists using telehealth inside of the UIowa Zoom ecosystem.
Behavioral: Cognitive Behavioral Therapy for Insomnia
Cognitive Behavioral Therapy for Insomnia BEHAVIORAL
The CBT-i intervention will be delivered by clinical psychologists (overseen by an experienced PhD-level Clinical Psychologist) who have completed CBT-i training at the University of Iowa. CBT-i is modular, manualized (see example in miscellaneous attachments), and thus highly standardized. CBT-i is the recommended first line treatment for those with insomnia (improving sleep in 75% of these) and has also shown efficacy for improving sleep in those with sub-clinical insomnia and with stress disorders (e.g., PTSD). CBT-i will be delivered in 6, \~1 hour sessions across the course of 6-7 weeks and the topics covered in each session (in order) will be: 1) Sleep Basics, 2) Sleep Schedules, 3) Sleep Hygiene, 4) Stress Management:Relaxation, 5) Stress Management: Stop Worrying About Sleep, 6) Stress Management: Problem Solving.
The intervention sessions will be delivered using telehealth inside of the UIowa Zoom ecosystem using private links.
What researchers are measuring
Outcome measures describe what is being studied. They are not proof that a treatment works.
Primary measures
Flow mediated dilation
Time frame: Prior to and at the end of 6 week CBT-I intervention
Brachial artery flow mediated dilation will be measured as a non-invasive indicator of endothelial function.
Secondary measures
Heart Rate Variabiliy
Time frame: Prior to and at the end of 6 week CBT-I intervention
Heart rate signals will be recorded using 3-lead ECG for 10 minutes while the participant rests quietly for measurement of heart rate and heart rate variability
Beat to beat blood pressure variability
Time frame: Prior to and at the end of 6 week CBT-I intervention
Beat-to-beat blood pressure signals will be recorded using finger photoplethysmography for 10 minutes while the participant rests quietly for measurement of blood pressure and blood pressure variability
Homeostatic Model Assessment of Insulin Resistance
Time frame: Prior to and at the end of 6 week CBT-I intervention
A fasting blood sample will be drawn to calculate HOMA-IR as (fasting glucose \[mg/dL\] x fasting insulin \[uIU/mL\] / 405)
Other measures
Waist Circumference
Time frame: Prior to and at the end of 6 week CBT-I intervention
Participants will have their waist circumference measured using a flexible Gulick tape.
