WORKSITE PHYSICAL ACTIVITY INTERVENTION AND HEALTH Physical activity (PA) at the recommended levels is known to prolong life, reduce risk for cardiovascular diseases (heart attack, stroke, and atherosclerosis), risk of diabetes, and risk of certain types of cancer (American College of Sports Medicine, 2014). The most recent national survey on PA habits among Norwegian adults found that only 32% satisfied the recommendations of 150 minutes of moderate PA, or 75 minutes of high intensity PA per week (Hansen et al., 2015). Despite of public education campaigns and intensive media attention to health benefits of regular PA, the changes in activity levels among Norwegians are surprisingly small. There is a need for more knowledge on how health promotion initiatives in non-treatment settings should be designed in order to support adults in increasing and maintaining their level of regular PA. For several decades, the worksite has been regarded as an important context for health promotion initiatives aimed at increasing PA levels of the adult non-clinical population (Conn, Hafdal, Cooper, Brown, & Lusk, 2009). Due to the presence of natural social networks, employer-initiated programs can potentially enhance the degree of commitment to and support for lifestyle changes from colleagues and management (Abraham & GrahamRowe, 2009; Rongen, Robroek, van Lenthe, & Burdorf, 2013). Despite the apparent advantages of the worksite context, health promotion programs can potentially be perceived a controlling and an intrusion to private life. Fear for negative reactions or pressure from colleagues and supervisors is a common reason for not participating in such programs (Linnan, Weiner, Graham, & Emmons, 2007). Hence, carefully designing the programs in order to avoid a sense of coercion is of pivotal importance, both for long-term behavioral change and for the well-being of employees.
