Study type
Description of intervention(s) / exposure
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.

Comparator / control treatment
Participants within the control workplaces will be advised that the aims of the study are to examine the patterns of physical activity and sedentary time in office workers, and how these may be associated with cardio-metabolic and anthropometric markers. The control group will receive the same assessments as the intervention group at the same time-points.
Control group

Primary outcome [1] 262312 0
A 30 minutes/day reduction in objectively-assessed (using physical activity monitors) workplace sedentary time
Timepoint [1] 262312 0
baseline, 3 months, 9 months
Primary outcome [2] 269211 0
An increase of 5 breaks/day in workplace sedentary time, objectively measured using physical activity monitors
Timepoint [2] 269211 0
baseline, 3 months, 9 months
Secondary outcome [1] 273507 0
Objectively measured non-workplace sedentary time and physical activity time. Sitting time and physical activity levels will be measured using an ActiGraph accelerometer (instensity of activity) and an activPAL inclinometer (posture)
Timepoint [1] 273507 0
baseline, 3 months, 9 months
Secondary outcome [2] 273508 0
Examine the effect of the intervention on cardiometabolic markers of health and disease including:
1) body composition inclusing waist circumference, BMI, and percent fat mass using bioimpedance analysis
2) fasting blood levels of glucose, insulin and lipids analysed by an accredited pathology laboratory
3) blood pressure will be measured by an Omron automatic blood pressure monitor
Timepoint [2] 273508 0
baseline, 3 months, 9 months
Secondary outcome [3] 279130 0
Explore workplace and individual-level mediators (how did the intervention work?) and moderators (for whom did it work?) of change using a specially formulated questionnaire
Timepoint [3] 279130 0
baseline, 3 months, 9 months

Study design
Purpose of the study
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
This trial involves cluster randomisation of whole workplaces to the Intervention or Control arms, rather than individual partcipants. Stratification will be based on workplace size (small: 20-50 employees, large: 51-70 employees) in order to obtain balanced numbers of sites and employees in the Intervention and the Control arms. Sites will be enrolled and then randomised until the required sample size is reached.

Allocation concealment is done via central randomisation by computer.

Brief summary
Researchers from the Baker IDI Heart & Diabetes Institute in Melbourne, University of Queensland, University of Melbourne and Deakin University are collaborating with Department of Human Services to measure the physical activity levels of office workers and to investigate the relationship between physical activity and health. Research over the last decade has shown that low overall activity patterns throughout the day increase the risk of many chronic conditions such as type 2 diabetes, heart disease, and some cancers.
Findings from this project will provide us with valuable information to develop and improve workplace health promotion programs.
