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 .
A Cluster Randomized Controlled Trial to Reduce Office Workers' Sitting Time: Effect on Activity Outcomes.
PURPOSE This study aim ed to evaluate the initial and long-term effectiveness of a workplace intervention compared with usual practice , targeting the reduction of sitting on activity outcomes . METHODS Office worksites ( ≥1 km apart ) from a single organization in Victoria , Australia , were cluster r and omized to intervention ( n = 7 ) or control ( n = 7 ) . Participants were 231 desk-based office workers ( 5 - 39 participants per worksite ) working at least 0.6 full-time equivalent . The workplace-delivered intervention addressed organizational , physical environment , and individual behavioral changes to reduce sitting time . Assessment s occurred at baseline , 3 months , and 12 months , with the primary outcome participants ' objective ly measured ( activPAL3 device ) workplace sitting time ( minutes per 8-h workday ) . Secondary activity outcomes were workplace time spent st and ing , stepping ( light , moderate to vigorous , and total ) , and in prolonged ( ≥30 min ) sitting bouts ( hours per 8-h workday ) ; usual duration of workplace sitting bouts ; and overall sitting , st and ing , and stepping time ( minutes per 16-h day ) . Analysis was by linear mixed models , accounting for repeated- measures and clustering and adjusting for baseline values and potential confounders . RESULTS At baseline , on average , participants ( 68 % women ; mean ± SD age = 45.6 ± 9.4 yr ) sat , stood , and stepped for 78.8 % ± 9.5 % , 14.3 % ± 8.2 % , and 6.9 % ± 2.9 % of work hours , respectively . Workplace sitting time was significantly reduced in the intervention group compared with the controls at 3 months ( -99.1 [ 95 % confidence interval = -116.3 to -81.8 ] min per 8-h workday ) and 12 months ( -45.4 [ -64.6 to -26.2 ] min per 8-h workday ) . Significant intervention effects ( all favoring intervention ) were observed for st and ing , prolonged sitting , and usual sitting bout duration at work , as well as overall sitting and st and ing time , with no significant or meaningful effects observed for stepping . CONCLUSIONS This workplace-delivered multicomponent intervention was successful at reducing workplace and overall daily sitting time in both the short term and the long term
