Reducing office workers’ sitting time: rationale and study design for the Stand Up Victoria cluster randomized trial
Background Excessive time spent in sedentary behaviours ( sitting or lying with low energy expenditure ) is associated with an increased risk for type 2 diabetes , cardiovascular disease and some cancers . Desk-based office workers typically accumulate high amounts of daily sitting time , often in prolonged unbroken bouts . The St and Up Victoria study aims to determine whether a 3-month multi-component intervention in the office setting reduces workplace sitting , particularly prolonged , unbroken sitting time , and results in improvements in cardio-metabolic biomarkers and work-related outcomes , compared to usual practice . Methods / Design A two-arm cluster-r and omized controlled trial ( RCT ) , with worksites as the unit of r and omization , will be conducted in 16 worksites located in Victoria , Australia . Work units from one organisation ( Department of Human Services , Australian Government ) will be allocated to either the multi-component intervention ( organisational , environmental [ height-adjustable workstations ] , and individual behavioural strategies ) or to a usual practice control group . The recruitment target is 160 participants ( office-based workers aged 18–65 years and working at least 0.6 full time equivalent ) per arm . At each assessment ( 0- [ baseline ] , 3- [ post intervention ] , and 12-months [ follow-up ] ) , objective measurement via the activPAL3 activity monitor will be used to assess workplace : sitting time ( primary outcome ) ; prolonged sitting time ( sitting time accrued in bouts of ≥30 minutes ) ; st and ing time ; sit-to-st and transitions ; and , moving time . Additional outcomes assessed will include : non-workplace activity ; cardio-metabolic biomarkers and health indicators ( including fasting glucose , lipids and insulin ; anthropometric measures ; blood pressure ; and , musculoskeletal symptoms ) ; and , work-related outcomes ( presenteeism , absenteeism , productivity , work performance ) . Incremental cost-effectiveness and identification of both workplace and individual-level mediators and moderators of change will also be evaluated . Discussion St and Up Victoria will be the first cluster- RCT to evaluate the effectiveness of a multi-component intervention aim ed at reducing prolonged workplace sitting in office workers . Strengths include the objective measurement of activity and assessment of the intervention on markers of cardio-metabolic health . Health- and work-related benefits , as well as the cost-effectiveness of the intervention , will help to inform future occupational practice .Trial registration
