One Step at a Time: An Intervention to Reduce Sedentary Behavior Among Working Adults
Study Details
Study Description
Brief Summary
The proposed study will test the preliminary efficacy of a novel 12-week social cognitive theory-based intervention that will target reducing daily sitting time and increasing exercise participation among middle-aged working adults. This is a population highly susceptible to excessive sedentary time and low levels of exercise engagement. This two-arm randomized controlled trial (RCT) will examine the preliminary efficacy of decreasing sedentary time in addition to increasing moderate-vigorous intensity physical activity (MVPA) engagement, compared to a group which only receives MVPA promotion.

|---|---|
| Experimental: Decrease Sedentary Time + Increase MVPA Participants in this group will receive a 12-week, social cognitive theory-based intervention targetting reduction of daily sedentary time. This information will be delivered to them in the form of Zoom workshops, a program workbook, personalized step count goals, and a private social media page. The aim of this component will be to have participants displace their daily sedentary time with light-intensity physical activity, such as casual walking. The second component of this intervention will be increasing participants' weekly MVPA engagement. Participants will participate in 1 live, virtual aerobics-based exercise class per week and complete 2 additional sessions on their own time. Participants will build up to exercising 150 minutes/week (the federal physical activity recommendations). |
Behavioral: Decrease Sedentary Time + Increase MVPA group
12 week home-based exercise program to promote engagement of 150 min/week of moderate-vigorous intensity exercise; personalized step count goals to increase daily volume of physical activity and displacement of sedentary time
|
| Active Comparator: Increase MVPA only Participants in this group will only receive the MVPA-promoting component (which will be the same delivery as the intervention group). Participants in this arm will participate in 1 live, virtual aerobics-based exercise class per week (held separately from the intervention group) and will complete 2 additional exercise classes on their own time. Participants will build up to exercising 150 minutes/week (the federal physical activity recommendations). |
Behavioral: Increase MVPA group

Outcome Measures
Primary Outcome Measures
- Changes in average daily step counts [Baseline,12 weeks]
Participants will wear a hip-based pedometer for 7 days at baseline and 12 weeks
- Changes in average daily sedentary time [Baseline,12 weeks]
Participants will wear a hip-based accelerometer for 7 days at baseline and 12 weeks to measure their daily time spent sedentary.
- Changes in average daily light-intensity physical activity [Baseline,12 weeks]
Participants will wear a hip-based accelerometer for 7 days at baseline and 12 weeks to measure their daily time spent engaged in light-intensity physical activity.
- Changes in average daily moderate-vigorous intensity physical activity [Baseline, 12 weeks]
Participants will wear a hip-based accelerometer for 7 days at baseline and 12 weeks to measure their daily time spent engaged in moderate-vigorous intensity physical activity.
