Sleep Promotion and Pediatric Hypertension

Determine the effectiveness and feasibility of a mobile health sleep extension approach in the pediatric nephrology setting, to increase sleep duration and reduce systolic and diastolic blood pressure.

Insufficient sleep is associated with hypertension in children. Despite this knowledge, sleep promotion is not considered as a behavioral target during the initial treatment of pediatric essential hypertension. Investigators are developing a mobile platform to promote sleep in children that may have utility for treating pediatric essential hypertension.

The overall objective of this study is to determine the effectiveness and feasibility of a mobile health sleep extension approach in the pediatric nephrology setting, to increase sleep duration and reduce systolic and diastolic blood pressure.

This is a home-based, single-site study, of 13-to-18-year-olds (N=10, 5 parent-child dyads). Participants will have a recent diagnosis of essential hypertension, based on clinical ambulatory blood pressure monitoring, with initial treatment targeting lifestyle modification without pharmacological therapy. Participants must have cellular or internet access and spend less than or equal to 7.5 hours in bed per night. Children will be excluded if they have a known clinical sleep disorder.

The sleep promotion intervention will be delivered using REDCap. All participants will be provided with a sleep tracker to monitor their sleep patterns throughout the study. A two-week run-in phase will be used to capture baseline sleep patterns, and a home sleep polysomnography test will be completed to provide clinical sleep data. During a 7-week intervention phase, all participants will receive the same intervention condition. Participants will be provided a sleep duration goal paired with a loss-framed financial incentive (virtual account) starting with deductions each time the sleep goal is not met, will be sent sleep guidance text messages, and will receive weekly performance feedback text messages. Further, at the end of the intervention phase, participants will undergo a second Ambulatory Blood Pressure Monitoring (ABPM). The primary outcome is acceptance and feasibility of completing this study captured via self-reported feedback and documenting compliance with the study protocol. The secondary outcomes are changes in sleep duration from baseline, and changes in daytime and nocturnal systolic and diastolic blood pressure from baseline.
