The aim of this study is to investigate how daily activity centers in Sweden work to promote physical health for people with intellectual disabilities. According to Swedish authorities, people with intellectual disabilities experience poorer physical health compared to the general population. The vulnerability of this group is further supported by previous research, which highlights their increased risk of physical conditions and an elevated risk of premature death. Some obstacles in the health-promoting work are mentioned in previous research, however, there is limited knowledge about how these obstacles can be addressed, as well as about the conflict between the individual´s self-determination and the staff´s health-promoting role. This study was carried out using a qualitative method through eight semi-structured interviews with managers and employees at daily activity centers in a municipality in southern Sweden. The empirical material was analyzed using a reflexive thematic analysis. The results indicated that the employees use different strategies to be able to motivate participants of daily activity centers to physical activities. Our results also found that daily activity centers face different opportunities in health-promotion work based on a variety of factors, such as the structures of the activity centers or the needs of the participants. A key conclusion we drew was that motivation and self-determination are important factors in increasing participants' willingness to engage in physical activity.
