A research group has recently published two meta-analyses – one on the effects of active workstations on reducing work sedentary time, and one examining the effectiveness of multi-component interventions to reduce workplace sedentary behaviour. Meta-analyses combine the results from multiple studies, and thus can provide higher quality evidence than a single study. They can also provide information on how consistent the effect of an intervention is when tested in different populations and different settings. Active workstations include sit-stand desks, under-desk cycles and treadmill desks. The first review examined the impact of different types of active workstation interventions on work-specific sedentary time. Concomitant strategies, such as prompting or individual support as well as multicomponent approaches, were also considered. A total of 23 eligible studies with 1428 office workers were included in the review. The meta-analysis showed that compared to a typical desk (i.e., a non-active one), sit-stand workstations either by themselves, or when used as part of a multi-component intervention or with promotion (e.g., prompts) were effective at reducing work sedentary time in office workers, as were treadmill workstations when used with promotion. Notably, multicomponent interventions and active workstations plus promotion showed greater effectiveness than active workstations alone – a finding consistent with…
