Locating fast-food outlets near schools is a potential public health risk to schoolchildren, given the easy access and repeated exposure to energy-dense, nutrient-poor foods they provide. Fast-food outlet availability near schools has not been previously investigated in Perth, Western Australia. This study aimed to quantify fast-food outlet availability near Perth schools and determine whether differences in area-level disadvantage and school type exist. Fast-food outlet locations were sourced from Perth Local Governments in 2018/2019. All Perth Primary (n=454), Secondary (n=107) and K-12 (n=94) schools were assigned an area-level disadvantage decile ranking based on the Australian Bureau of Statistics Socio-Economic Index for Areas (SEIFA). Regression models assessed whether fast-food outlet availability within 400 m, 800 m and 1km of schools differed by school type (ie, Primary/Secondary/K-12) or SEIFA. Secondary schools were significantly more likely than Primary and K-12 schools to have a higher presence and density of fast-food outlets and the "Top 4" fast-food outlet chains (McDonalds, Hungry Jacks, KFC and Red Rooster) nearby. Schools located in low socio-economic status (SES) areas had a significantly higher density of fast-food outlets within 400 m, and "Top 4" fast-food outlet chains within 400 m and 1km, than schools located in high SES area. Perth schools are surrounded by fast-food outlets with densities significantly higher around secondary schools and schools located in lower SES areas. SO WHAT?: Policies and regulations aimed at reducing fast-food outlets near schools is an essential strategy to improve dietary intakes and reduce obesity in schoolchildren.
