简要总结
Despite their importance, health-related behaviors are hard to change. Among behaviors, physical activity is associated with protection from multiple diseases. People who are physically active have lower risk for heart disease, stroke, type 2 diabetes, depression, and some cancers with associated dose-dependent reductions in cardiovascular and all-cause mortality. However, most US adults do not meet CDC physical activity guidelines. Sedentary work behavior in industrialized nations is likely a contributor to this problem.
Current low-technology strategies for encouraging lifestyle change are disappointingly ineffective and are highly resource intensive. Systematic reviews of the literature show mixed evidence for using activity trackers (i.e., pedometers) and a limited body of evidence for text messaging in preventive health care. However, prior studies have not integrated digital activity tracking with mobile phone text messaging feedback.
Given 91% of adults in the United States now use a mobile phone, and 56% a smartphone, this represents a potentially widely applicable avenue for therapeutic intervention. There is growing interest in leveraging mobile health (mHealth) technologies to improve health behaviors in the general population. The investigators propose to conduct a blinded, randomized mHealth trial of digital activity tracking and smart texting to promote physical activity.
详细描述
Using an innovative, convenient, mHealth trial design, this pilot study aims to test the feasibility of a seamless model of information flow integrating digital activity tracker information with a mobile phone texting system to deliver a technology-enhanced intervention that does not require in-person follow-up.
The investigators hypothesize that:
- individuals overestimate their physical activity, especially that done at work.
- biofeedback from an activity tracker can increase physical activity via increasing self-awareness.
- "smart" text message feedback can increase physical activity via personalizing health coaching.
Digitalized activity tracking will use the Fitbug Orb, which syncs via Bluetooth with one's smartphone. It is a display-free triaxial accelerometer, allowing one to blind participants to numeric feedback. Text messaging will use Reify Health's "smart" platform for personalized, interactive texting by an automated and repeatable algorithm. Texting will be informed by real-time activity information.
Potential advantages of the trial strategy include elimination of attendance at in-person sessions, personalization of health coaching, more continuous patient contact; inexpensive intervention, the ultimate ability to scale our intervention to larger target populations.

结局指标
主要结局
Mean Daily Step Count
时间窗: Change from 3 weeks mean daily step count at 5 weeks (end of smart text messaging intervention)
Note that the study occurred over two study phases after the 1-week blinded run-in. In the first 2-week phase, participants were randomized to unblinded or blinded tracking. In the second 2-week phase, the unblinded participants were randomized to receive smart texts or no texts.
次要结局
- Mean Daily Activity Time(Change from 3 weeks mean daily activity time at 5 weeks (end of smart text messaging intervention))
- Mean Daily Aerobic Activity Time(Change from 3 weeks mean daily aerobic activity time at 5 weeks (end of smart text messaging intervention))
