Although desk-based workers spend much of their time at work sitting, little is known about how office spaces may be related to workplace sitting time. This study examined cross-sectional associations of the perceived availability of office shared spaces with workersĄŻ sitting time, and the potential role of workplace normative-social factors in the relationship. Participants (N = 221) wore an activity monitor (activPAL3) and reported availability of shared spaces (for formal meetings, informal discussion, collaborative working), organizational norms, and workplace behavioral autonomy. No shared-space variables were associated with workplace sitting time. However, the perceived availability of sufficient informal discussion space was associated with lower levels of sitting among those who reported more-supportive organizational norms and greater behavioral autonomy. These findings highlight environmental, organizational, and psychosocial factors that will be important to address in future initiatives to reduce work place sitting time %K sedentary behavior %K office environment %K work space %K desk-based work %K prolonged sitting %U https://journals.sagepub.com/doi/full/10.1177/0013916518772014
