Summary
Reducing sedentary time effectively displaces it into light physical activity and standing, both at work and daily. However, changes in stepping or moderate-to-vigorous physical activity depend on the intervention setting.
Area of Science:
- Public Health
- Behavioral Science
- Occupational Health
Background:
- Sedentary behavior interventions effectively reduce sitting time.
- The displacement of reduced sedentary time remains understudied.
Approach:
- Systematic review and meta-analysis of 36 studies.
- Investigated the reallocation of sedentary time into various physical activities.
Key Points:
- Interventions significantly increased worksite and daily light physical activity.
- Significant increases observed in daily moderate-to-vigorous physical activity.
- Worksite and daily standing time significantly increased, as did worksite stepping time.
Conclusions:
- Reduced sedentary time consistently displaces to light physical activity and standing.
- Changes in stepping and moderate-to-vigorous physical activity are setting-dependent.
- Interventions should extend beyond worksites to promote daily moderate-to-vigorous physical activity.
