By Anna Rasmussen On the 4th October it was Diabetes Australia Walk to Work Day. Walking has become an integral part of my daily routine. I spend between two and ten hours each week walking to and from destinations including university or the hospital where I study, the weekend markets, or the shops. The World Health Organisation has acknowledged active transport as a way to improve global environmental and health outcomes. My motivations are primarily to benefit my physical and mental health, but walking has other benefits such as being non-polluting, posing little danger to others, saving money, and, perhaps mostly importantly, I enjoy it. I am, however, one of the minority in Australia that uses walking as their main form of transit. The 2016 Census found that 69% Australian commuters travelled to work by car, and another 5% as car passengers, while 9% used public transport, 1% cycled, 4% walked, and 4% used multiple methods. This is largely consistent with rates from 2011, with a 0.5% rise in driving a car and a 0.7% increase in train use, while cycling and walking declined 0.1% and 0.3% respectively. Furthermore, infrastructure and culture is becoming increasingly car-centric. This is not to…
Benefits to heart health of reducing workplace sitting
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…
