Office and call center workers ’ steps/day were among the lowest , while those of postal delivery workers were highest .
Office workers had the greatest ST and the lowest time in LPA both at work and during wakeful time .
Laborers had the lowest ST and spent a significantly greater proportion of their work time in LPA and MVPA .
Healthcare and protective services workers had higher levels of LPA at work compared to other occupations .
Workers in driving-based occupations tended to have a higher body mass index and blood pressure .
Conclusion This review identifies that occupational and wakeful time PA and ST differed between occupations .
Background With approximately 8 hours of one ’s waking day spent at work , occupational tasks and environments are important influencers on an individual ’s physical activity ( PA ) and sedentary behaviours .
Little research has compared device-measured physical activity , sedentary behaviour and cardiometabolic outcomes between occupational groups .
Objective To compare device-measured movement ( sedentary time [ ST ] , light intensity  physical activity [ LPA ] , moderate-to-vigorous intensity physical activity [ MVPA ] , and steps ) across occupations .
The secondary objective was to examine whether cardiometabolic and fitness outcomes differed by occupation .
Reducing sitting time in office workers: short-term efficacy of a multicomponent intervention.
OBJECTIVE To investigate the short-term efficacy of a multicomponent intervention to reduce office workers ' sitting time . METHODS Allocation for this non-r and omized controlled trial ( n=43 participants ; 56 % women ; 26 - 62 years ; Melbourne , Australia ) was by office floor , with data collected during July-September 2011 . The 4-week intervention emphasized three key messages : " St and Up , Sit Less , Move More " and comprised organizational , environmental , and individual elements . Changes in minutes/day at the workplace spent sitting ( primary outcome ) , in prolonged sitting ( sitting time accumulated in bouts ≥ 30 min ) , st and ing , and moving were objective ly measured ( activPAL3 ) . RESULTS Relative to the controls , the intervention group significantly reduced workplace sitting time ( mean change [ 95%CI ] : -125 [ -161 , -89 ] min/8-h workday ) , with changes primarily driven by a reduction in prolonged sitting time ( -73 [ -108 , -40 ] min/8-h workday ) . Workplace sitting was almost exclusively replaced by st and ing ( + 127 [ + 92 , + 162 ] min/8-h workday ) with non-significant changes to stepping time ( -2 [ -7 , + 4 ] min/8-h workday ) and number of steps ( -70 [ -350 , 210 ] ) . CONCLUSIONS This multicomponent workplace intervention demonstrated that substantial reductions in sitting time are achievable in an office setting . Larger studies with longer timeframes are needed to assess sustainability of these changes , as well as their potential longer-term impacts on health and work-related outcomes
