Clinical Trial Summary

This study aims to increase weekly minutes of moderate-to-vigorous physical activity and improve sleep quality in a sample of mid-life adults between ages 50 and 64 years.

Description:

This 2-year study will develop, test, and refine a cloud-based feedback system, and evaluate the impact of a 3 month randomized controlled feasibility pilot intervention - the Bio-behavioral systems to Motivate and Reinforce Heart Health trial (Be SMART) on changes in moderate-to-vigorous physical activity (MVPA) and sleep among mid-life adults between ages 50 and 64 years.

Aim 1 will examine the acceptability of the Be SMART system. We will conduct a 6-week proof- of-concept study in 10 mid-life adults to specifically examine recruitment plausibility, adherence and attrition rates, satisfaction, and implementation fidelity.

Aim 2 will quantify the impact of the Be SMART intervention (n=30) on changes in MVPA and sleep metrics compared to a Fitbit-only condition (n=30) among mid-life adults (N=60). Hypothesis 2a: At 3 months, participants in the Be SMART condition will show significantly greater weekly minutes of MVPA compared to the Fitbit-only condition, controlling for baseline. Hypothesis 2b: At 3 months, participants in the Be SMART condition will be significantly more likely to report adequate sleep duration, shorter sleep latency, and earlier sleep timing, compared to the Fitbit-only condition, controlling for baseline.

Aim 3 will explore the extent to which changes in MVPA and sleep metrics impact blood pressure changes among mid-life adults (N=60). Secondly, this study will quantify the extent to which Be SMART participants (n=30) achieve their weekly goals and if goal achievement impacts changes in blood pressure at 3 months. Hypothesis 3a: Changes in MVPA and sleep metrics will be related to changes in blood pressure. Hypothesis 3b, the degree of goal achievement will be related to changes in blood pressure.

Intervention

Behavioral:
• Be SMART
The behavioral intervention will examine 12-week changes in sleep metrics and physical activity, compared to baseline measures, between subjects randomly assigned to a treatment (Be SMART) and an active control (Fitbit Only) condition (n=30, respectively).
