Food environments surrounding schools have a strong influence on the adolescent's food choices. Moreover, the prevalence of diet-related chronic diseases is higher in regional than metropolitan areas in Australia. Understanding school food environments in these different settings is crucial for informing future strategies to improve adolescent health.
Google Street View was used to identify food outlets within 1.6 km around all secondary schools in Wagga Wagga and Blacktown in New South Wales which were selected as regional and metropolitan case study areas. Based on food outlet type, healthfulness categories were assigned, and Chi-squared tests were performed. The Health Advisory Panel for Youth at the University of Sydney (HAPYUS) were engaged to obtain their perspectives on findings.
Unhealthful food outlets were consistently most prevalent around schools in Wagga Wagga and Blacktown over 17 years. In 2023, these were predominantly restaurants (19.4% vs. 21.1%), cafés (16.8% vs. 11.1%), fast-food franchise outlets (15.1% vs. 17.4%) and independent takeaway stores (14.1% vs. 9.6%). No significant difference in healthfulness between regional and metropolitan areas was found. Youth advisors recognised price and social reasons as major contributors to food choices.
Google Street View was used as a novel resource to examine school food environments in regional and metropolitan areas which have remained consistently unhealthful for nearly two decades. SO WHAT?: Unhealthful school food environments may encourage poor diets and exacerbate rates of adolescent overweight and obesity. Critical government action is needed to improve school food environments.
学校周边的食物环境对青少年的食物选择有很大影响。此外，在澳大利亚，与饮食相关的慢性病在地区的患病率高于大城市地区。了解这些不同环境下的学校食物环境对于制定改善青少年健康的未来策略至关重要。
利用谷歌街景视图识别新南威尔士州瓦加瓦加和布莱克敦所有中学周边1.6公里范围内的食品店，这两个地区分别被选为地区和大城市的案例研究区域。根据食品店类型划分健康类别，并进行卡方检验。悉尼大学青年健康咨询小组（HAPYUS）参与其中，以获取他们对研究结果的看法。
在17年的时间里，不健康食品店在瓦加瓦加和布莱克敦的学校周边一直最为普遍。2023年，这些主要是餐馆（19.4%对21.1%）、咖啡馆（16.8%对11.1%）、快餐连锁店（15.1%对17.4%）和独立外卖店（14.1%对9.6%）。未发现地区和大城市地区在健康程度上有显著差异。青年顾问认为价格和社会因素是食物选择的主要影响因素。
谷歌街景视图被用作一种新颖的资源，来研究地区和大城市地区的学校食物环境，近二十年来这些环境一直不健康。那又如何？：不健康的学校食物环境可能会助长不良饮食，并加剧青少年超重和肥胖率。政府需要采取关键行动来改善学校食物环境。
