The study found a significant association between the density of major fast-food chain outlets near Australian secondary schools and the frequency of students' discretionary food purchases, suggesting that restricting these outlets near schools may help reduce adolescents' discretionary food intake.
Objectives: We sought to investigate the association between food-outlet availability near Australian second-ary schools and frequency of Australian students' discretionary food purchases. Methods: Secondary-school students in Perth (Western Australia) reported the frequency of their discretion-ary food purchases from food outlets near their school (17 schools, n = 2389 students grades 7-12, ages 12-17 y). Food-outlet availability was sourced from local governments, then geocoded. A mixed-effects model was used in analyses. 3Results: Almost half of students (45%) purchased discretionary foods from food outlets near their secondary school at least weekly. Only the density of top-ranking fast-food chain outlets near secondary schools was associated with a significant increase in the frequency of discretionary food purchases. Conclusions: Availability of major fast-food chains near Australian secondary schools appears to be a key driver of Australian students' discretionary food purchasing. Restricting these outlets near schools may help reduce adolescents' discretionary food intake.3 (c) 2021 Elsevier Inc. All rights reserved.
