YoPA: Youth-led changes to neighborhood spaces and daily routines to improve activity, sleep, and screen habits

YoPA - A Youth-centred Participatory Action Approach Towards Co-created Implementation of Socially and Physically Activating Environmental Interventions in Africa and Europe.

Not applicable Interventional Amsterdam UMC, location VUmc · NCT06181162

This project will try a youth-centred co-creation approach to change social and physical environments so 12–18 year-olds in disadvantaged urban areas are more active, sleep better, and use screens less harmfully.

What this trial studies

YoPA uses participatory action and co-creation with adolescents to design and implement social and physical environmental interventions aimed at improving 24-hour movement behaviours. The work is being carried out in disadvantaged urban neighborhoods in Denmark, the Netherlands, Nigeria, and South Africa. Local youth, caregivers, and stakeholders collaborate with researchers to tailor interventions to each setting, then implement and evaluate their effects on physical activity, sedentary behaviour, sleep, and screen use. The project emphasizes sustainable, context-sensitive changes at the neighborhood and systems level rather than one-off individual programs.

Who should consider this trial

Good fit: Adolescents aged 12–18 who live in designated disadvantaged areas of Aalborg (Denmark), Amsterdam (the Netherlands), Osogbo (Nigeria), or Soweto (South Africa) and can provide active informed consent (and parent/caregiver consent where applicable).

Not a fit: Young people who live outside the specified locations, are not in disadvantaged urban neighborhoods, or who cannot or will not engage in co-creation activities are unlikely to benefit from participation.

Why it matters

Potential benefit: If successful, the approach could produce sustainable neighborhood and school changes that improve adolescents' activity, sleep, and screen habits and reduce long-term risk for chronic diseases.

How similar studies have performed: There is growing evidence that co-designed, environment-focused interventions can improve youth activity and related behaviours, but results vary by context and sustained effects are not consistently demonstrated.
