Occupational Sitting Time, Leisure Physical Activity, and All-Cause and Cardiovascular Disease Mortality
jan 24 JAMA
These findings suggest that reducing prolonged sitting in the workplace and/or increasing the volume or intensity of daily physical activity may be beneficial in mitigating the elevated risks of all-cause mortality and cardiovascular disease associated with prolonged occupational sitting.
In this cohort study, we found that individuals who mostly sit at work had higher mortality risks than those who mostly do not sit at work.
Our findings have several implications for interventions. First, the observed attenuated risk among individuals who alternate between sitting and nonsitting at work suggests that incorporating regular breaks in work settings can be beneficial. These breaks can be facilitated through the use of wearable devices43 or structured employer-designed break times. Experimental studies have explored the effectiveness of such interventions, revealing positive effects on metabolic outcomes.44 Practical solutions such as standing tables and activity-permissive workstations can also reduce sedentary time at work effectively without compromising work performance.45 Second, our findings offer reassurance that the increased risks can be offset by an extra 15 to 30 minutes per day of exercise per day or by participating in more physically intense activities. Employers can play a role in facilitating this by providing designated areas for LTPA or offering company-sponsored group activities.
