This cross-sectional study aimed to evaluate the association between the consumption of healthy and unhealthy food markers among adolescents enrolled in the ninth grade of elementary school in municipal public schools and the food environment around the schools in two municipalities of different sizes, located in Southern Brazil. The data were collected between 2022 and 2023, with 449 adolescent participants. Of these, 347 were students from the municipality of Florianópolis, and 102 were students from the municipality of Governador Celso Ramos, all aged between 13 and 17 years. The establishments located around the schools were evaluated using AUDITNOVA, an instrument that investigates the environmental dimension and food dimension. The consumption of healthy eating markers (beans, vegetables, and fresh fruits) and unhealthy eating markers (ultra-processed foods, soft drinks, sweets, and fried snacks) among students was assessed using a food frequency questionnaire. Statistically significant associations were observed between the food environment around the school and the consumption of unhealthy food markers (OR = 0.63; 95% CI = 0.41-0.98 = 0.041) but only in the large municipality. No significant associations were found in the students' food consumption in the small municipality. A significant association between the school food environment and adolescents' consumption of unhealthy foods was observed in Florianópolis. Healthy food consumption was low among students in the small municipality, Governador Celso Ramos.
本横断面研究旨在评估南里奥格兰德州两个不同规模城市的公立学校 9 年级初中生的健康和不健康食物标志物消费与学校周围食物环境之间的关联。数据于 2022 年至 2023 年期间采集，共有 449 名青少年参与者。其中，347 名来自弗洛里亚诺波利斯市，102 名来自卡塞雷斯拉姆市长市，年龄均在 13 至 17 岁之间。使用 AUDITNOVA 评估学校周围的场所，该工具调查环境维度和食物维度。使用食物频率问卷评估学生健康饮食标志物（豆类、蔬菜和新鲜水果）和不健康饮食标志物（超加工食品、软饮料、糖果和油炸小吃）的消费情况。在校内食物环境与不健康食物标志物消费之间观察到了统计学上显著的关联（OR = 0.63；95%CI = 0.41-0.98 = 0.041），但仅在大城市中存在这种关联。在小城市中，学生的食物消费没有发现显著关联。在弗洛里亚诺波利斯，校内食物环境与青少年食用不健康食物之间存在显著关联。在小城市卡塞雷斯拉姆，学生的健康食物消费较低。
