Introduction and aim

An alarmingly low number of children meet public health guidelines for physical activity and healthy dietary behaviors, and are at increased risk of developing lifestyle-related diseases. Importantly, this burden is already unequally distributed at an early age. Unhealthy lifestyle behaviors are driven by complex mechanisms that differ across boys and girls growing up under different socio-economic circumstances.

Outdoor play is an important contributor to children’s levels of physical activity. Yet, children growing up in underprivileged neighborhoods play less outside due to limited access to safe and attractive outdoor spaces and appropriate and affordable after-school activities than other children. At the same time, today’s children have abundant access to inexpensive energy-dense foods and online sedentary activities.

B-challenged aims to tackle the complexity of equality in children’s active outdoor play and healthy dietary behaviors by co-creating, implementing, and evaluating interventions in the physical and social environment together with children growing up in socio-economically underprivileged neighborhoods and other key actors (e.g., parents, teachers, and policymakers).

Our study

This study is an EU project and will be conducted in underprivileged neighborhoods across four countries: the Netherlands, Poland, Spain, and Denmark. The Danish segment of the study is led by the World Playground Research Institute and will be centered in Rudkøbing, Langeland.


This study runs from 2024-2027.

What we expect

This study holds significant potential for real-world impact as it strives to address challenges related to healthy lifestyles and generate new insights into co-creating health interventions with children living in underprivileged neighborhoods.
