HYPERTENSION
This study aims to test the effects of a real-world behavioral sleep extension intervention on sleep and cardiometabolic health among adults with elevated BP/stage I/II hypertension and short sleep duration. Despite the effectiveness of other behavioral sleep medicine treatments, such as cognitive behavioral therapy for insomnia (CBT-I) [The main feature of our intervention is the use of coaching combined with wearable technology to motivate behavior change. In our previous research, the use of consumer sleep technology was rated as highly desirable to individuals with short sleep duration and, in our intervention development, was rated as the most enjoyable aspect of the study [An important limitation to note is that this intervention focuses on extending sleep among individuals who are able to extend their sleep opportunity. We acknowledge that the causes of short sleep duration are multifactorial, and only some aspects are modifiable. Particularly relevant to communities of color, longstanding structural barriers affect sleep contributing to disparities cardiometabolic disease risk [In summary, the results of this study will demonstrate the short-term (8 weeks) and longer-term (12 months) effects of behavioral sleep extension. Future research is needed to study in other populations, biopsychosocial contributors to individual differences in who can and cannot extend sleep and also to understand interventions geared toward maintenance of behavior change.
