What do Workers do to Reduce Their Sitting Time?

The Relationships of Strategy use and Workplace Support with Desk-Based Workers' Behaviour Changes in a Workplace-Delivered Sitting-Reduction and Activity-Promoting Intervention
Objective: To explore workers' sitting-reduction and activity-promoting strategy use following an intervention targeting these changes, and whether strategy use and perceived workplace support impacted on three-month sitting and activity outcomes.
Methods: This secondary analysis in desk-based workers (n = 83) utilised data collected on questionnaire-derived strategy use and workplace support, and activPAL3TM-derived sitting (total; prolonged, ≥30mins) and activity (standing; stepping) at work.
Results: Fourteen strategies were commonly used during the intervention. Increased usage of some strategies were significantly (p < 0.05) associated with beneficial changes in prolonged sitting or stepping only. Workplace support was significantly beneficially associated with changes in sitting, prolonged sitting, and stepping; these associations were largely independent of strategy use changes.
Conclusions: Strategies were highly used, with increased use associated with some behavioural improvements. Workplace support appears essential for improving sitting and activity in the workplace.
