Authors: Ida Høgstedt Danquah (presenting and corresponding), Stine Kloster, Janne Schurmann Tolstrup Purpose Multicomponent workplace-based sitting interventions targeting office workers are becoming increasingly popular, however, the implementation process is often not evaluated. Take a Stand! was a multicomponent workplace-based sitting intervention targeting office workers that resulted in reduced sitting time by 71 minutes after one month. Participants in the intervention group came from offices with different characteristics and the implementation process varied between offices. Thus, the aim is to assess which factors, e.g. in the context or initiation, affected the implementation process and how these factors are related to the effect size in Take a Stand! Methods In the present study the intervention offices from Take a Stand!, a cluster-randomized controlled trial, were included, resulting in 173 participants from 10 offices (office size ranged from 10 to 33 with a mean of 17 (SD=8)). Descriptive statistics were used to analyze questionnaire data and activity data from participants clustered at office level. Directed content analysis was used for the qualitative analysis of interviews with participants, ambassadors and leaders. Categories for analysis were taken from the Framework for Evaluating Organizational-level Interventions. Results/findings Changes in sitting time compared to baseline varied between offices from -4 to -133 minutes at 1 month and 4 to -72 minutes at 3 months. Preliminary results from the qualitative analyses showed that participants found management support very important, especially because they felt they needed approval to participate in intervention activities. Additionally, it seemed that involving employees and ensuring positive attitude at the very beginning of the project was crucial, as well as the timing of the project in relation to other changes at the workplace. Conclusions This study systematically describes factors that are important for successful implementation of a multicomponent sitting intervention at the workplace. This is relevant for future workplace interventions, mainly related to sitting, but results could also be relevant for other health interventions at the workplace, e.g. on physical activity or nutrition.
