Abstract

Objective: To explore the potential of a sitting reduction workplace intervention for improving stress and work-performance.

Methods: A cluster randomised controlled trial evaluated an intervention to reduce and break up occupational sitting in 12 clusters (n = 89 office workers) over eight weeks. Outcomes were physiological stress (cortisol concentrations), perceived stress and work-performance.

Results: Linear mixed model group x time interaction effects were non-significant. Exploratory analyses showed a trend, with a large effect, for lower cortisol concentrations over the day in the intervention group relative to controls at 8 weeks (-0.85; 95% CI -1.70, 0.03 nmol.L-1; p = 0.06; d = 0.79). The intervention group had higher vigour and cognitive liveliness at eight weeks relative to controls (p ≤ 0.05).

Conclusions: This exploratory study suggests there could be meaningful changes in physiological stress and work-related outcomes that should be investigated in future studies.
