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

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.

Inclusion criteria

  • 45-65 years of age by study start date
  • Hold full-time employment (≥ 30 hours/week) at one or more jobs
  • Hold a sedentary-based job (which also allows for ability to freely move about during the workday)
  • Low active (engage in ≤2 days of 30+ minutes of structured moderate-vigorous intensity exercise/week)
  • Physician's consent to participate in aerobic testing and/or the exercise program (if needed based on Physical Activity Readiness Questionnaire responses)
  • Ambulatory
  • Absence of health conditions that may be made worse by exercise
  • Ability to complete all testing assessments in-person
  • Access to a laptop/desktop/phone with Zoom web-conferencing software
  • Fluent in English

Exclusion criteria

  • Under 45 or over 65 years of age
  • 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)
  • High active (engage in > 2 days or 30+ minutes of structured moderate-vigorous intensity exercise/week)
  • 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.
  • Unable to complete assessments in-person
  • No access to laptop/desktop/phone with Zoom software

Treatment and study plan

Decrease Sedentary Time + Increase MVPA group

Behavioral

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

Increase MVPA group

Behavioral

12 week home-based exercise program to promote engagement of 150 min/week of moderate-vigorous intensity exercise

Primary outcomes

  1. Changes in average daily step counts

    Time frame: Baseline,12 weeks

    Participants will wear a hip-based pedometer for 7 days at baseline and 12 weeks

  2. Changes in average daily sedentary time

    Time frame: 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.

  3. Changes in average daily light-intensity physical activity

    Time frame: 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.

  4. Changes in average daily moderate-vigorous intensity physical activity

    Time frame: 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.
