Skin cancer is a significant public health concern in Aotearoa New Zealand (A/NZ) where we have the highest mortality rate globally.(1) Protecting children from excessive ultraviolet radiation (UVR), sunburn, and skin damage during play activities ideally includes providing shade in public spaces where children congregate. This study aimed to assess shade availability in all playgrounds managed by local governments across A/NZ. The methods used were validated in a previous study.(2-4)
A comprehensive census of all 3,491 playgrounds available in the 67 local government areas was conducted. Recent satellite images and eye-level photographs were obtained for every playground. Google Street View was primarily utilised for eye-level photographs, with on-site photographs taken if the playground was obscured or the image was over 5 years old. A network of volunteers assisted with this. A shade audit was conducted for each playground recording the size of the play area, the 'supervision zone' (within 10 meters of the play equipment), and shade coverage in square meters. Other variables collected included shade availability for play equipment, seating, and picnic tables; shade type (built, natural, shade sails); neighborhood deprivation level; latitude and longitude; climatic factors; playground size; playground type; rurality; and other amenities. Our presentation will analyze shade coverage across different playground characteristics, considering factors that impact shade provision. Additionally, we will discuss the evidence-based advocacy tool currently being developed for local governments to encourage quality shade provision in recreational areas. This initiative aims to mitigate UVR exposure amongst children reducing their risk of skin cancer.
