INTRODUCTION: Research suggests that participating in after-school leisure activities has been related to promoting health, well-being and safety among children living in disadvantaged neighbourhoods. The United Nations Child Rights Convention emphasises the inclusion of children in decisions that concern them. However, children seldom are involved in designing implementing and evaluating health promotional environments. The aim of this programme is through a participatory process with children, parents/guardians, and peer-activity leaders explore, measure and evaluate the impact on children's overall well-being related to the social context in an already established health promotion environments in Southern Sweden.

METHODS AND ANALYSIS: The project is based on a previously implemented unique community-based participatory research (CBPR) model for equal health in three socially disadvantaged areas in Malmö. All activity house (AAH) is a meeting place for children established in schools but after school time by the culture department of the Malmö municipality. In AAH migrant children participate in need-driven after school activities that they themselves create and develop. To increase participation of the children and ensure that these environments are based on their needs, 30 children (10-12 years), parents/guardians (30), peer-activity leaders (15), and researchers create CBPR teams in the areas and engage in a participatory process. The children reflect, analyse and write about their well-being; identify and discuss key factors in an iterative process, which also includes a strategic group of stakeholders. The children then develop and validate (with 100 other children from AAH) the Socioculturally Aligned Survey Instrument for Children survey inspired by the KIDSSCREEN V.27. The survey tool so developed will further be used to evaluate AAH and will be distributed to all children participating in their activities.

ETHICS AND DISSEMINATION: This programme has been approved by the Swedish Ethical Review Authority. The results from this programme will be published as reports and scientific publication.
