Promoting access to leisure time physical activity (LTPA) opportunities for children and youth is crucial to promote public health. Yet, ensuring sustainable interventions in this field requires theoretically informed approaches to guide the processes of developing, implementing and evaluating LTPA programs. The objective of this review was to examine how concepts of equality and equity have been operationalized in LTPA interventions for children and youth in order to identify facilitating factors and barriers to LTPA access connected to such concepts. Using a pre-piloted search strategy, three electronic databases were searched for studies of interventions aiming to promote access to LTPA in organized or community sport for children and youth. Following a screening process, 27 publications representing 25 unique interventions were included. Through careful examination of the aim and target group of each intervention, they emerged in three categories in accordance with their (implicit) understandings of equality and equity. Also, considering the processes through which the interventions within each category had been implemented leads to the conclusion that an explicit theoretical understanding of the aim of interventions will increase communal knowledge among intervention stakeholders about which facilitating factors to pursue and barriers to bypass to contribute to more socially sustainable LTPA programs.
