Des études antérieures font état d’une diminution du temps passé assis sur le lieu de travail lorsque des interventions sur les bureaux debout sont proposées aux employés de bureau. Il n’est pas clair si la diminution des comportements sédentaires est maintenue à long terme. Il s’agissait du suivi d’une étude d’intervention précédente visant à déterminer si les diminutions du temps d’assise de 30 à 50 % observées étaient maintenues 12 à 24 mois plus tard. Un objectif secondaire était de comparer l’activité physique globale des employés de bureau avec et sans bureau debout.
Previous studies report decreased workplace sitting time when standing desk interventions are provided to office workers. It is unclear whether decreased sedentary behaviours are maintained long-term. This was a follow-up to a previous intervention study to investigate whether observed sitting time decreases of 30–50% were sustained 12–24 months later. A secondary aim was to compare overall physical activity between office workers with and without standing desks. Although sitting time increased over the follow-up period, this did not reach significance and reductions in workplace sitting remained significantly lower (23.5% decrease) from baseline values. There were no differences in the physical activity measures between workers with and without access to standing desks, although this was a small sample size and further research is needed. Individuals who are motivated to try standing desks at work can benefit through decreased sitting time long-term, however this may not extend to increased overall physical activity levels. Practitioner summary: Providing standing desk options to office-based employees can have long-lasting impacts with reducing sitting time at work. Office workers who choose to stand at work do not appear to compensate with overall activity level reduction outside of work.Abbreviations: LBP: low back pain; OSPAQ: occupational sitting and physical activity questionnaire; VAS: visual analog scale; ANOVA: analysis of variance; BMI: body mass index; ICC: intraclass correlation coefficient
