Conclusion
This investigation confirms that short-term height-adjustable sit-stand interventions are effective in reducing workplace sitting time and selected health outcomes. While the effect sizes were small, the results are encouraging, and they suggest that even short-term interventions can have a positive effect on health. Further research is warranted to validate these findings and to explore the long-term impact of a sit-to-stand workstation on reducing sedentary behaviour and enhancing the health outcomes of office workers in South Africa.
