We know that significant reductions in workplace sitting are achievable. But how does reducing sitting impact on workers’ health? We examined this using data from our Stand Up Victoria intervention – a 12 month intervention in office workers that used organizational-, environmental- (including sit-stand workstations) and individual-level approaches to reduce prolonged workplace sitting time in desk-based workers. What did we do? We recruited 14 work teams and over 200 workers (136 intervention; 95 control) from the one organisation to take part in this cluster randomised controlled trial. We measured 14 biomarkers of body composition, blood pressure, glucose metabolism, lipid metabolism and a composite overall cardio-metabolic risk score in both the intervention and control participants at three time points: before the intervention, after three months of the intervention (end of the intensive intervention phase), and after 12 months. What did we find? We found a significant, beneficial intervention effect for fasting glucose and the clustered metabolic risk score at the 12 month assessment. This beneficial effect for fasting glucose was mainly due to the control group getting worse over the 12 months. There were no significant intervention effects observed at 3 months. Notably, sitting was primarily replaced with standing. What does this…
