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

Not Applicable

Completed

• Conditions: Exercise; Sedentary Behavior; Adult; Middle Age

• 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.

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.
