This thesis was conducted within a community-based participatory research (CBPR) program, initiated as a response to preceding health inequity commissions, and aiming to find innovative forms for health promotion. The overall aim of the thesis was to develop health promotion through CBPR, together with women with experience of migration in a socioeconomically disadvantaged neighborhood in Sweden. The CBPR approach guided the process, focusing on reflective dialogues and both qualitative and quantitative data collection methods were used. As a point of departure for the process, an identification of conditions for health and of actions to promote it, was made together with participants. The actions were developed in collaboration into various activities, and the participants pointed out contributors that made them engage in health-promoting activities: lay health promoters, having a place to meet, and social cohesion. The knowledge brought forward about health issues and health promotion within the community was used in the development of a CBPR intervention addressing type 2 diabetes. The intervention was a collaboration between the community and other actors and included reflective dialogues and workshops, conducted as group activities. In the mixed-method evaluation, it was found that stress and waist circumference were reduced, and that social support was crucial throughout the process, in providing motivation to engage in the activities and in promoting health.
