儿童肥胖率高引起了政策制定者改善学校饮食环境和提高学生体育活动水平的兴趣。本研究的目的是调查加拿大不列颠哥伦比亚省与学校食品和饮料销售 (FBSS) 和每日体育活动 (DPA) 指南实施相关的学校层面的变化。中小学校长在 2007-08 年 (N = 513) 和 2011-12 年 (N = 490) 完成了学校食品和体育活动环境调查。分层混合效应回归用于检查以下方面的变化：1）食品和饮料的可用性； 2) 每天体育（PE）分钟； 3）PE的交付方式； 4) 学校社区支持。控制学校入学率和社区类型、教育和收入的模型。预计政策实施后，更多小学提供水果和蔬菜，而提供 100% 果汁的小学则较少。提供含糖饮料、炸薯条、烘焙食品、咸味零食和巧克力/糖果的初中/高中较少。学校更有可能为 6 年级学生提供每周 150 分钟的体育活动，并为 8 年级和 10 年级学生每周提供更多分钟的体育活动，包括改变体育教学方式。随着时间的推移，学校社区对营养和体育活动政策的支持不断增加。在学校预计实施 FBSS 和 DPA 指南后，学校食品环境发生了积极变化。据报道，学校环境的变化令人鼓舞，并为注重增加学校健康饮食和体育活动的指导方针和政策提供了支持。
High rates of childhood obesity have generated interest among policy makers to improve the school food environment and increase students’ levels of physical activity. The purpose of this study was to examine school-level changes associated with implementation of the Food and Beverage Sales in Schools (FBSS) and Daily Physical Activity (DPA) guidelines in British Columbia, Canada. Elementary and middle/high school principals completed a survey on the school food and physical activity environment in 2007–08 (N = 513) and 2011–12 (N = 490). Hierarchical mixed effects regression was used to examine changes in: 1) availability of food and beverages; 2) minutes per day of Physical Education (PE); 3) delivery method of PE; and 4) school community support. Models controlled for school enrollment and community type, education and income. After policy implementation was expected, more elementary schools provided access to fruits and vegetables and less to 100% fruit juice. Fewer middle/high schools provided access to sugar-sweetened beverages, French fries, baked goods, salty snacks and chocolate/candy. Schools were more likely to meet 150 min/week of PE for grade 6 students, and offer more minutes of PE per week for grade 8 and 10 students including changes to PE delivery method. School community support for nutrition and physical activity policies increased over time. Positive changes to the school food environment occurred after schools were expected to implement the FBSS and DPA guidelines. Reported changes to the school environment are encouraging and provide support for guidelines and policies that focus on increasing healthy eating and physical activity in schools.
