1014 Technology Assisted Behavior Intervention To Extend Sleep Among Adults With Short Sleep Duration And Prehypertension/stage 1 Hypertension: A Randomized Pilot Feasibility Study

Abstract

Introduction: Short sleep duration contributes to hypertension yet few behavioral sleep extension interventions have been developed. The goal of our study was to evaluate the feasibility and preliminary efficacy of a technology‐assisted sleep extension intervention among individuals with prehypertension/stage I hypertension on sleep, blood pressure and patient reported outcomes. Methods: Adults aged 30‐65 with 24h ambulatory blood pressure (ABP) >120/80 mmHg and average weekday sleep duration <7 h per night were randomized 2:1 to a 6 week technology‐assisted intervention versus a self‐management control group. The intervention included a wearable sleep tracker, smartphone application, weekly didactic lessons and brief telephone coaching. The control group was instructed to maintain their current sleep schedule. Data were analyzed using descriptive statistics and nonparametric statistics to evaluate differences in between groups as well as pre‐post changes within each group. We also conducted bivariate correlations to evaluate predictors of change in sleep and ABP. Results: A total of 16 adults were randomized into the study (11 intervention, 6 control group, 8 women, M=45.8 SD=9.8 years.) Results at 6 week follow‐up demonstrated greater improvement in the intervention group for total sleep time (0.57 versus 0.08 hours, p=.027), reductions in 24h SBP (‐9 versus 0 mmHg, p=.013) and DBP (‐5 versus ‐2 mmHg, p=.026), improvements in self report measures including reductions in sleep disturbance (‐7 versus 5 t‐score points, p=.003) and sleep related impairment (‐10 versus 2 t‐score points, p=.008). Conclusion: Technology‐assisted sleep extension intervention is feasible and well liked in this population. Results demonstrate the potential for this intervention to improve sleep duration, quality and 24‐h BP.
