! Given the links between sedentary behavior and health, this study examines the relationships between office workers' objectively measured sedentary behavior patterns, several workplace spatial characteristics, presenteeism (the extent to which health conditions adversely affect at-work productivity), and levels of environmental satisfaction. Several significant links were identified between workplace spatial characteristics and sedentary behavior at work, with the most significant being self-reported distance from coffee/break area and the Space Syntax measure of connectivity. The evidence collected was used to inform design suggestions to encourage more active work styles for office workers. !
