Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Participants allocated to the intervention group will participate in a 12-week worksite-based physical activity intervention based around increasing their average daily work day steps. The intervention will comprise 2 distinct treatment phases targeting behaviour adoption (weeks 1-4) and adherence (weeks 5-12) using ‘Stages of Behaviour Change’ principles. The adoption phase of the walking intervention will consist of individually targeted supervised 60-minute education/information group sessions of 5-6 participants held once per week. The adoption pahase group sessions will be facilitated by a physiotherapist or exercise physiologist. Participants will discuss the benefits of becoming more active; how to initiate behaviours to achieve activity goals; how to identify strategies for overcoming lapses etc); how to set individual steps per day goals; and how to self monitor progress using the pedometer and a walking diary to record work day steps. Each session will conclude with a 20 minute group walk. The adherence phase of the walking intervention will be self-directed and remotely monitored to encourage participant compliance and progression. Participants will select their own preferred walking option(s) from three alteratives, depending on their own life circumstances or individual preference with the intention of progressively increasing average work day steps. The first of these walking options, termed “walking routes” will use prescribed walks around the campus over which participants will be asked to complete at least 20-30 minutes of continuous, brisk walking every work day. The second walking option, termed “walking within tasks” will encourage participants to accumulate step counts throughout the working day. Rather than prescribed routes, the office, lectures and seminars will be targeted as environments where tasks could be completed standing and walking, rather than sitting, for example “walk and talk” tutorials or meetings. The third walking option, termed “walking for transport” will provide participants with an information pack to facilitate safe walking to and/or from work, using identified walking paths and public transport facilities. Particpiants will be encouraged to select a mix the options from day-to-day depending on their preferences.

Outcomes
Primary outcome [1] 258213 0
Average work day step count: will be measured by pedometer (Yamax SW-200) and averaged over five working days at each time point
Timepoint [1] 258213 0
Pre-intervention (baseline), end adoption phase (end week 4) and post-intervention (end week 12).
Secondary outcome [1] 263862 0
Physical health status: will be measured by three standard measures of cardiovascular and metabolic health
1. Blood pressure: duplicate measures of systolic and diastolic blood pressure (BP) will be taken two minutes apart using an automated device Microlife BP A 100; Microlife AG, Widnau, Switzerland) after the participant has rested in a seated position for five minutes.
2. Waist circumference: duplicate measurements of the waist circumference will be made at the level of the trunk where the girth is minimal (i.e. where there is a noticeable indentation of the trunk), usually 1 inch or 2.5 cm above the umbilicus, or if there is no noticeable indentation the tape will be located at the umbilicus. A steel tape measure KDS F10-02 (KDS Corporation, Japan) will be used to ensure the tape does not stretch during measurement.
3. Body fat percentage will be assessed by bioelectrical impedance analysis procedures using an electronic body composition analyzer (Tanita BF 350; Tanita Corporation, Tokyo Japan) following recommended procedures.
Timepoint [1] 263862 0
Pre-intervention (baseline), and post-intervention (end week 12).
Secondary outcome [2] 263863 0
Mental health status: The psychological wellbeing of participants will be measured by a validated self-administered questionnaire; Kessler-10.
Timepoint [2] 263863 0
Pre-intervention (baseline), and post-intervention (end week 12).
Secondary outcome [3] 263864 0
Physical activity participation: will be measured by the validated Active Australia Survey
Timepoint [3] 263864 0
Pre-intervention (baseline), and post-intervention (end week 12).
Secondary outcome [4] 263865 0
Work ability - will be measured by two self administered questionnaires: the Work Ability Index (Australia) which is an adaption of the Work Ability Index (WAI); and by the Work Ability Survey (WAS).
Timepoint [4] 263865 0
Pre-intervention (baseline), and post-intervention (end week 12).

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Participants will be randomly allocated to treatment group using sealed opaque envelopes.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
The computer program generated allocation sequence will be produced by a researcher not involved in recruitment or assessment of participants at baseline prior to group allocation
