About this study
FIT4Life is a text message based physical activity project that includes one baseline week and 26 weeks of intervention delivery. Study participants will be provided with fitness trackers to support their physical activity goals. The text messages are intended to motivate participants to engage in physical activity throughout the week, but do not prescribe specific exercises/workout regimens for participants to follow.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
text messagesBehavioural
There will be two arms for the texting intervention: high and low. Both arms will receive text messages, but the frequency of the messages will vary by arm. Text intervention messaging will be sent through an automated text messaging service programmed by the CM Research Informatics team, which has been approved by the institution.
| Study group | Role | What they receive |
|---|---|---|
| High Arm | Experimental | High-arm participants will receive daily messages related to wear reminders, encouragements, congratulatory content, and behavior change based on the activity tracker data. Step counts from the activity tracker are included in some messages to track and facilitate step goals. Some text message content asks for a response from the participant to help tailor later messages for behavior change support. Receives: Behavioral: text messages |
| Low Arm | Experimental | Low arm participants will receive weekly messages related to reminders to wear their activity tracker and tips on how to use the tracker. Receives: Behavioral: text messages |
What is being measured
The primary outcome is the main question the study is designed to answer.
Acceptability and preferences
Descriptive analyses will be used to analyze the survey data and qualitative thematic analyses will be used to analyze interview data to determine participant preferences and program acceptability.
Measured: From enrollment to the end of program at 27 weeks
Secondary outcomes (2)
Change in Physical Activity Minutes
Longitudinal models will be used to investigate changes in physical activity minutes over time, from before (baseline) to after the intervention.
Measured: From enrollment to the end of program at 27 weeks
Change in Physical Steps
Longitudinal models will be used to investigate changes in steps over time, from before (baseline) to after the intervention.
Measured: From enrollment to the end of program at 27 weeks
