The 2020 World Health Organization guidelines emphasized reducing sedentary behaviors, prompting a study in Taiwan to explore the health risks associated with prolonged occupational sitting. Conducted from 1996 to 2017, the prospective cohort study aimed to identify if there's a threshold of physical activity that can mitigate these risks. Data on occupational sitting, leisure-time physical activity (LTPA), lifestyle, and metabolic parameters were analyzed to assess the impact of prolonged sitting on health.
The study followed up 481,688 participants for a mean period of 12.85 years. The researchers found that prolonged occupational sitting was linked to a 16% higher all-cause mortality risk and a 34% higher risk of cardiovascular disease (CVD) mortality. Those mainly sitting at work had elevated risks compared to those mostly nonsitting. Individuals alternating sitting and nonsitting at work did not show similar increased mortality risk. For those mainly sitting at work with low or no leisure-time physical activity (LTPA), increasing LTPA by 15 or 30 minutes daily reduced mortality risk. Those with a personal activity intelligence (PAI) score over 100 showed a notable reduction in elevated mortality risk linked to prolonged sitting.
Study reveals harms of prolonged occupational sitting, but alternating between sitting and nonsitting at work, together with adding an extra 15 to 30 minutes per day of LTPA or achieving a PAI score greater than 100, reduced these harms.
