Intervention
A single-blinded randomized controlled trial (RCT) was conducted with a total of 122 participants that were randomly assigned to either the intervention or control group. The group allocation was conducted by a qualified biostatistician independent from the core research team to randomly assign participants into control and intervention. The intervention group consisted of (n = 62, 51%) participants, while the control group had (n = 60, 49%) participants. Participants in the intervention group were provided with a height adjustable sit-to-stand workstation (JUMBO DeskStand™, DeskStand, South Africa) as previously described in the protocol [The control group participants continued to use their traditional desks and were informed verbally about the negative health effects of prolonged sitting. The researcher did not interact with the control group participants during the intervention period, except to collect baseline and follow-up data at 12 weeks.
