Clinical Trial Summary

The goal of this study is to test the efficacy of a behavioral sleep extension intervention on sleep duration, cardio-metabolic disease risk factors, and health behaviors among adults with elevated blood pressure/hypertension and short sleep duration.

Description:

Half of U.S. adults have at least one cardio-metabolic disease (CMD), including hypertension (HTN), heart disease, stroke, or diabetes. Even with advances in screening, education, and medication management, controlling these chronic diseases remains challenging. Despite the well-established negative effects of short sleep duration, surprisingly few studies have tested the benefits of sleep extension and even fewer studies evaluate the science of sleep extension interventions. Therefore, the goal of this study is to test the efficacy of a behavioral sleep extension intervention on sleep duration, CMD risk factors, and health behaviors among adults with elevated BP/HTN and short sleep duration.

Eligibility

Inclusion Criteria:

• Age 18-65

• 24h ABP readings indicating elevated blood pressure (BP) or hypertension (24h average systolic (SBP) of 115-145 mmHg or diastolic (DBP) of 75-90 mmHg). Patients taking antihypertensive medications will be permitted if stable dose for >8 weeks

• Unstable or serious medical illness that would interfere with participation (cancer, renal disease on dialysis)

• Overnight work more than 1x per month

• Use of hypnotic or stimulant medications

• Situations that would significantly impact the ability to extend sleep, including overnight caregiving responsibility for children under the age 1, elderly or disabled adults >1x per week

• Inability to read or write in English

• Pregnancy/desire to become pregnant during the study period.
