Abstract: | Objective: The aim of the study is to explore the potential of a sitting reduction workplace intervention for improving stress and work performance. Methods: A cluster randomized controlled trial evaluated an intervention to reduce and break up occupational sitting in 12 clusters (n = 89 office workers) over 8 weeks. Outcomes were physiological stress (cortisol concentrations), perceived stress, and work performance. Results: Linear mixed model group × time interaction effects were nonsignificant. 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% confidence interval, −1.70 to 0.03 nmol·L−1; P = 0.06, d = 0.79). The intervention group had higher vigor and cognitive liveliness at 8 weeks relative to controls (P ≤ 0.05). Conclusions: This exploratory study suggests that there could be meaningful changes in physiological stress and work-related outcomes that should be investigated in future studies. |
Description: | The study presented in this article adhered to the CONSORT reporting guidelines for cluster randomized trials. |
