Sit-stand desk interventions are deployed to reduce sedentary time and improve ergonomic adjustability in modern workplaces, with ultimate goals of improving health and productivity. Sit-stand desks, however, require workers to take an active role in changing the desk position, and usage compliance of the sit-stand function has been a challenge. This study used computer software to objectively record continuous data on electric sit-stand desk usage during computer use, to understand current desk usage behaviors in a large office environment involving ∼300 workers for 3 months. We found that workers completed roughly one desk position change per work day, and one-fourth of the workers always had the desk in a seated position (during computer use). The methods used here demonstrate a novel approach to record sit-stand desk usage continuously during active computer use.

Physical inactivity is a major public health threat: inactive adults are at an elevated risk of early death, heart disease, stroke, type 2 diabetes, and depression. Despite these dire consequences, fewer than half of American adults meet the recommended guidelines for daily physical activity. Sedentary jobs contribute to this problem, but the workplace also presents an opportunity for intervention.

"Effect of frequent interruptions of prolonged sitting on self-perceived levels of energy, mood, food cravings and cognitive function." International Journal of Behavioral Nutrition and Physical Activity, November 3, 2016.

While physical activity has been shown to improve cognitive performance and well-being, office workers are essentially sedentary. We compared the effects of physical activity performed as (i) one bout in the morning or (ii) as microbouts spread out across the day to (iii) a day spent sitting, on mood and energy levels and cognitive function.

Importance  Leisure-time physical activity has been associated with lower risk of heart-disease and all-cause mortality, but its association with risk of cancer is not well understood.

Objective  To determine the association of leisure-time physical activity with incidence of common types of cancer and whether associations vary by body size and/or smoking.
