The Evidence

Prolonged sitting time links to subclinical atherosclerosis

A new study titled “Prolonged sitting time links to subclinical atherosclerosis”, recently been published in the Journal of the Chinese Medical Association, investigated the link between daily sitting time and subclinical atherosclerosis by using coronary computed tomography angiography (CCTA). Sitting time is a parameter that is used for the evaluation of physical activity and is associated with total mortality, but the evidence is less clear for coronary artery disease. A 2015 study reported that prolonged sitting time (>9 hours/d) is associated with the incidence of nonalcoholic fatty liver disease, and is a risk factor for obesity, suggesting that prolonged sitting time might be a risk factor for atherosclerosis. The study enrolled 203 subjects who underwent CCTA at annual medical checkups. Subjects were age 57.6 ±8.8 years. Sitting time was categorised as < 5 hours/day (short), 5 to 9 hours/day (moderate) and ≥10 hours/d (long). Researchers analysed the coronary calcium score, plaque characteristics and severity of coronary artery stenosis, including the segment involvement score (SIS) and segment stenosis score (SSS). The study found that subjects with longer sitting times tended to be male gender and have lower levels of high-density lipoprotein cholesterol. In addition, those with longer sitting time had higher…

Champion Insights – How BeUpstanding has Impacted Workplace Culture

The BeUpstanding program was developed to support work teams to address the emergent work health and safety issue of excessive sitting.  Through taking part in the program, it is hoped that the various strategies teams implement to sit less and move more in the workplace lead to sustainable changes in their organisation and create a culture where sitting less and moving more is the norm. In order to evaluate the impact of BeUpstanding, champions taking part in the national trial of BeUpstanding complete a survey through the online toolkit at three timepoints in the trial – prior to launching the program, upon completion of the 8-week program, and 12 months after launching the program. Champions also take part in a phone call with a member of the BeUpstanding team at these same time points and are asked a series of questions about their experience. During their 12-month sustainability phone call with a BeUpstanding team member, champions were asked the following question about their workplace; “To what extent do you feel the workplace culture and norms have changed to support sitting less and moving more?” Here are some of their responses: “We include the BeUpstanding program as part of our induction…
