A systematic review of the risk factors and interventions for the prevention of playground injuries

Objectives The primary objectives of this work were to (1) identify the risk and/or protective factors associated with playground injuries among children less than 18 years of age and (2) identify interventions/programs/policies aimed at preventing playground-related injuries among children less than 18 years of age. Secondary objectives include a summary of the data that reflect alignment with current playground standards. Methods For the primary outcome, 4 databases and 12 online resources were systematically searched to include observational and experimental studies examining risk and/or protective factors or interventions associated with playground injury or outcomes related to playground injury (e.g., risky playground behaviour). Data extraction included study design, participants, outcome, exposure or intervention, data analysis, and effect estimates. The quality of evidence for all studies was assessed using the Downs and Black criteria. Results This review included studies of moderate quality, revealing a number of risk factors and effective interventions for playground injury. Risk factors included absence of handrails and guardrails on playground equipment, non-impact-absorbing surfacing, and critical fall heights. Effective interventions included modifying playground surfacing and reducing equipment height to less than 1.5 m. Conclusion Equipment-and structure-based playgrounds should adhere to and maintain playground standards in order to reduce the risk of serious injury. Organizations responsible for installing and maintaining playgrounds should consider alternative play spaces that allow children to play outdoors, in a natural environment that supports healthy child development and promotes physical activity.
