Exploring experiences and perceptions of early withdrawal from a height-adjustable sit-to-stand desk intervention among South African office workers

BACKGROUND

The increasing sedentary behaviour and burden of non-communicable diseases among office workers raise significant concerns. Height-adjustable sit-to-stand desks offer a potential solution, yet uptake remains challenging, limiting their effectiveness and long-term adoption. The experiences of office workers who withdrew from a height-adjustable sit-to-stand desk intervention need to be explored to inform program refinement.

METHODS

A qualitative approach was used, with pre-identified themes guiding data collection, while subthemes emerged inductively from transcripts and field notes. Twelve participants with a mean age of 46.0 years were conveniently sampled. These office workers withdrew from a height-adjustable standing desk randomised controlled trial and did not form any part of other studies. One-on-one semi-structured interviews guided data collection about the participants' experiences and reasons for early withdrawal from the intervention. Data were thematically analysed using Atlas.ti 23.

RESULTS

Most participants were female (n = 10, 83.3%). All participants completed high school, while 41.7% completed a postgraduate degree from a university and credit bureau company. Despite the participants' understanding of the benefits of height-adjustable sit-to-stand workstations, most of the participants discontinued the intervention due to perceived barriers that aligned with the themes: "discomforts and dislikes", "applicability and practicality", "people's perception-i.e., what other people will say" and "transitioning to electronic sit-to-stand desks".

CONCLUSIONS

The findings of this study may assist in formulating a policy to improve compliance with height-adjustable sit-to-stand workstations in the workplace. Future studies should consider individual preferences, design, functionality, knowledge, and motivation to ensure effective implementation, utilisation, and compliance with height-adjustable sit-to-stand workstations.

Ukumela impilo randomised trial: preliminary findings of height-adjustable sit-to-stand workstations on health outcomes of South African office workers

BACKGROUND

The prevalence of sedentary behaviour has concurrently risen with multiple cardiometabolic risk markers independent of physical activity levels. Office-based workers accumulate the highest levels of sitting time during occupational times. This study aims to investigate the short-term effects of using height-adjustable sit-to-stand workstations on cardiometabolic risk markers of office-based workers in South Africa.

RESULTS

Sixty-two office-based workers were randomized into intervention (n = 44), and the control group (n = 18). Small improvements were observed in BMI, blood pressure, and cholesterol levels in this cohort.

CONCLUSION

This preliminary investigation confirms that short-term height-adjustable sit-stand interventions are effective in reducing workplace sitting time and selected health outcomes. South Africa has been attributed with the highest burden of obesity in Sub-Saharan Africa, as a result, there is a need to implement long-term workplace intervention to reverse these implications.
