Objective. Reducing sedentary behaviours at work is imperative. Before effective strategies can be developed there is a need to understand profiles of activity within particular roles and organizations. This study aimed to determine activity profiles of staff by job title at a UK university. Methods. Three-hundred and seventeen participants completed the international physical activity questionnaire - short form to determine physical activity profiles. Fifty-one participants also wore a wrist-worn GENEActiv accelerometer for 7 days and completed a self-report diary denoting work and leisure hours. Results. Twenty-one per cent of respondents were categorized as inactive and achieved 298 ± 178 metabolic equivalent minutes (MET-min)/week. Those in administrative roles were most sedentary (501 ± 161 min/day). Accelerometer data highlighted that sedentary time was identical between job roles (pooled mean 8746 ± 823 counts) and equated to 84 ± 9% of total time. During working hours, management, professional and specialist job roles had the highest level of sedentary time (2066 ± 416 counts). Conclusion. Time spent undertaking sedentary activities during working hours contributes to reduced overall activity and can impede productivity, performance and health. Interventions encouraging regular movement and preventing sedentary behaviours at work are therefore required.
