J Occup Environ Med. 2020 Jan;62(1):30-36. doi: 10.1097/JOM.0000000000001737.


Objective: Take a Stand! was a multicomponent workplace-based intervention reducing sitting among office-workers. This study tested whether the effect of Take a Stand! differed across subgroups.

Methods: A cluster-randomized controlled trial with objectively measured sitting-time as primary outcome evaluated Take a Stand! Main analysis was reanalyzed in strata defined by four levels of preselected factors: socio-demographic (eg, sex); health-related (eg, smoking); work-related (eg, workhours); and psychosocial (eg, motivation to change sitting).

Results: No notable differences in the effect were observed: across all assessed subgroups sitting time was ∼60 minutes less after 1 month and ∼40 minutes less after 3 months in intervention as compared with control group.

Conclusion: There was no differential effect of Take a Stand! indicating that the intervention was effective in all groups. This knowledge is advantageous when disseminating similar interventions to different populations of office workers.
