Stand Up Victoria: a trial to determine whether environmental modification and behavioural counselling can lead to reductions in workplace sitting time in office workers

The intervention lasts for 3 months and consists of four distinct components: (1) an initial Unit Representatives Consultation involving a broad range of Unit Representatives. This consultation will include an explanation of the role of organisational, environmental, and individual factors in determining occupational sitting time. Furthermore, unit representatives will be asked to workshop appropriate strategies to reduce sitting time at their workplace; (2) a whole-of-workplace Information Session. The session will (a) outline recent research findings on the health consequences of too much sitting, (b) provide a summary of what emerged in the Unit Representatives Consultation and (c) provide summary feedback of sedentary and activity time generated from the baseline assessment; (3) Environmental Modification involving installation of sit-to-stand workstations for individual participants. The sit-stand workstation allows the employee to easily alternate their working posture between sitting and standing; and (4) Support for Behavioural Change which includes (a) an initial one-on-one individual consultation with project staff (i.e. health promotion and allied health professionals) trained in motivational interviewing techniques and (b) four telephone support calls over 3 months in support of initiation and maintenance of sedentary behaviour change.
