Issue Addressed: Adolescents are heavily exposed to unhealthy outdoor food advertisements near schools, however, the marketing power of these advertisements among adolescents has not yet been explored. This study aimed to investigate the teen-directed marketing features present and quantify the overall marketing power of outdoor food advertisements located near schools to explore any differences by content (ie, alcohol, discretionary, core and miscellaneous foods) school type (ie, primary, secondary, K-12) and area-level socio-economic status (SES; ie, low vs high)., Methods: This cross-sectional study audited every outdoor food advertisement (n = 1518) within 500m of 64 randomly selected schools in Perth, Western Australia, using a teen-informed coding tool to score the marketing power of each advertisement., Results: Outdoor alcohol advertisements around schools had the highest average marketing power score and number of advertising features present. Outdoor advertisements for alcohol and discretionary foods scored significantly higher in marketing power than core food advertisements (P < .001). Outdoor alcohol advertisements around secondary schools scored significantly higher in marketing power than around primary and K-12 schools (P < .001); and outdoor advertisements for discretionary foods in low SES areas scored significantly higher in marketing power than those in high SES areas (P < .001)., Conclusions: This study found outdoor advertisements for unhealthy products, such as alcohol and discretionary foods, were more powerful than advertisements for core foods around schools. SO WHAT?: These findings strengthen the need for policies which restrict outdoor advertisements for non-core foods near schools, to reduce adolescents' exposure to powerful alcohol and discretionary food advertisements., (© 2023 Australian Health Promotion Association.)

Issue Addressed: Previous research has highlighted children's frequent exposure to advertisements of unhealthy food and beverages on television. However, the food industry is increasingly utilising non-broadcast channels such as outdoor advertising (eg billboards, bus shelters, shop fronts) for product marketing. Few studies have investigated children's exposure to outdoor food advertising around primary and secondary schools. This study aimed to quantify the presence and content of outdoor food advertisements within a 500 m radius of primary and secondary schools in Perth, Western Australia., Methods: A cross-sectional design was used to capture outdoor advertisements within a 500 m radial buffer around the school boundary. The INFORMAS protocol for monitoring outdoor advertising around child-serving institutions was used. Sixty-four primary and secondary schools in Perth, Australia, were selected using random sampling within socio-economic and population density strata., Results: In total, 5636 outdoor advertisements were identified within a 500 m radius of all 64 schools combined and 30% were for food. Of the 1708 food advertisements, 74% were for unhealthy (non-core) food. The most frequently advertised food products were alcohol, fast food and sugar-sweetened beverages. Only 8% of food advertisements featured a healthy product. The majority of schools (75%) had at least one food advertisement within 500 m (mean 36, range 3-190). Schools in lower socio-economic areas had more food advertisements and a significantly higher proportion of unhealthy food advertisements within 250 m., Conclusion: Outdoor advertising around schools constitutes a potential frequent source of children's exposure to unhealthy food and alcohol advertising. SO WHAT?: Policy interventions restricting the content of outdoor food advertising near schools are needed., (© 2021 Australian Health Promotion Association.)

Supermarkets have been described as having unprecedented and disproportionate power in the food system. This scoping review synthesized the literature that describes the position and power of supermarkets in the Australian food system, and the implications for public health. A systematic search of peer-reviewed and grey literature identified 68 documents that described supermarket power. Implications for public health were also recorded. Data revealed that supermarkets hold a powerful position in the Australian food system, acting as the primary gatekeepers. Supermarkets have obtained instrumental, structural and discursive power from many sources that overlap and reinforce each other. Few positive public health impacts of supermarket power were identified, providing many opportunities for improvement in the domains of food governance, the food system and public health nutrition. There is very little public health research examining the impact of supermarket power in Australia. More research is needed, and examination of supermarket own brands is of particular importance owing to their pivotal role as a source of power and their potential to improve public health outcomes, such as obesity., (© 2017 World Obesity Federation.)
