and sleep, posing major risks for developing multiple non-communicable diseases. Unhealthy lifestyles seem more prevalent in urban than rural areas, with the neighbourhood environment as a mediating pathway linking urban living and poor health. How to develop and implement sustainable and effective interventions focused on adolescent health and wellbeing in urban vulnerable life situations is a key challenge and research gap. This paper describes the protocol of a Youth-centred Participatory Action (YoPA) project aiming to tailor, implement, and evaluate social and physical environmental interventions using an evidence-informed youth-centred co-creation approach, for structural improvement of the lifestyles of adolescents in urban vulnerable life situations.\n\nMethods\n\nIn diverse urban environments in Denmark, the Netherlands, Nigeria, and South Africa, academic researchers will engage adolescents (12-19 years) growing up in vulnerable life situations and other key stakeholders (e.g., policy makers, urban planners, community leaders) in local co-creation communities. Together with academic researchers and local stakeholders, adolescents will take a leading role in mapping the local system for needs and opportunities; tailoring interventions to their local context; implementing and evaluating interventions during participatory meetings over the course of three years. YoPA applies a participatory mixed methods design guided by the newly developed SUPER-AIM framework assessing: (i) the local Systems, (ii) User perspectives, (iii) the Participatory co-creation process, (ii) Effects, iv) Reach, (vi) Adoption, (vii) Implementation, and (viii) Maintenance of interventions, in an integrated manner.\n\nDiscussion\n\nYoPA aims to fill various research gaps, including the development of a practical protocol guiding the application of co-creation to tailor evidence-informed interventions to divers, multi-country contexts. Additionally, it focuses on advancing the research gap in physical activity and health within Sub-Saharan Africa and the involvement of adolescents in shaping their physical and social environments. Academic researchers envision that the YoPA co-creation approach will serve as a guide for participation of adolescents in vulnerable life situations in implementation of health promotion and urban planning in Europe, Africa and globally.",[168,169,170,171],"Physical Activity","Health Promotion","Sleep","Screen Use",[173,169,174,175,176,177,178],"Participatory Action Research","Systems Approach","Adolescents","24-hour movement behaviour","Physical activity","Urban health","2025-09-11",{"date":181,"type":182},"2025-09-17","ACTUAL",{"date":184,"type":182},"2023-11-01",{"date":186,"type":162},"2026-12-31",{"name":5,"class":6},4]
