One Step at a Time: An Intervention to Reduce Sedentary Behavior Among Working Adults

Not Applicable

Completed

• Conditions: Exercise; Sedentary Behavior; Adult; Middle Age
• Interventions: Behavioral: Decrease Sedentary Time + Increase MVPA group; Behavioral: Increase MVPA group

• Registration Number: NCT05281978
• Lead Sponsor: University of Illinois at Urbana-Champaign

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.

• Not holding full-time employment (work < 30 hours/week at one or more jobs)
• Hold a job(s) which is classified as light, medium, heavy, or very heavy work
• Hold a sedentary-based job which does not allow for free movement throughout the workday (i.e., bus driver)

• Non-consent of physician
• Non-ambulatory (i.e., use of walkers, wheelchair, cane, etc.)
• Presence of health conditions that may be made worse by exercise.

Arm && Interventions

Group	Intervention	Description
Decrease Sedentary Time + Increase MVPA	Decrease Sedentary Time + Increase MVPA group	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).
Increase MVPA only	Increase MVPA group	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).

Primary Outcome Measures

Name	Time	Method
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.
