1Sansom Institute for Health Research, University of South Australia, Adelaide, South Australia, Australia (Mr Mazzotta, Dr McEvoy); Alliance for Research in Exercise, Nutrition and Activity (ARENA), School of Health Sciences, University of South Australia, Adelaide, South Australia, Australia (Drs Ferrar, Fraysse); Department of Physiotherapy, College of Nursing and Health Sciences, Flinders University, Adelaide, South Australia, Australia (Dr Lewis).
Objective:
No studies have objectively measured habitual usage of sit-stand workstations.
Methods:
Eighteen full-time office workers participated (47.9 ± 9.2 years, 61% female). Sitting time was objectively measured (activPAL, 24 h/7 days), and time at desk, desk position, and perceptions of desk use were self-reported.
Results:
Participants sat for 39% of their daily workstation time, and changed workstation position twice daily. The most common reasons for standing included back pain (44%) and tiredness (22%). The majority of participants received no workstation occupational health (72%) or educational (61%) information. Workstation standing time had a significant moderate correlation with total daily standing time (P = 0.02).
Conclusion:
Office workers with sit-stand workstations rarely change desk position, and there is no relationship between the time spent sitting at the workstation, and total daily sitting time. Education about the workstations was limited.
