We investigated the extent to which a sample of Ontario and Alberta secondary schools are being compliant with their respective provincial nutrition policies, in terms of the food and beverages sold in vending machines.
This observational study used objective data on drinks and snacks from vending machines, collected over three years of the COMPASS study (2012/2013-2014/2015 school years). Drink (e.g., sugar-containing carbonated/non-carbonated soft drinks, sports drinks, etc.) and snack (e.g., chips, crackers, etc.) data were coded by number of units available, price, and location of vending machine(s) in the school. Univariate and bivariate analyses were undertaken using R version 3.2.3. In order to assess policy compliancy over time, nutritional information of products in vending machines was compared to nutrition standards set out in P/PM 150 in Ontario, and those set out in the Alberta Nutrition Guidelines for Children and Youth (2012) in Alberta.
Results reveal a decline over time in the proportion of schools selling sugar-containing carbonated soft drinks (9% in 2012/2013 vs. 3% in 2014/2015), crackers (26% vs. 17%) and cake products (12% vs. 5%) in vending machines, and inconsistent changes in the proportion selling chips (53%, 67% and 65% over the three school years). Conversely, results highlight increases in the proportion of vending machines selling chocolate bars (7% vs. 13%) and cookies (21% vs. 40%) between the 2012/2013 and 2014/2015 school years.
Nutritional standard policies were not adhered to in the majority of schools with respect to vending machines. There is a need for investment in formal monitoring and evaluation of school policies, and the provision of information and tools to support nutrition policy implementation.
我们调查了安大略省和艾伯塔省的中学样本在自动售货机销售的食品和饮料方面，遵守各自省级营养政策的程度。
这项观察性研究使用了在COMPASS研究的三年（2012/2013 - 2014/2015学年）中收集的自动售货机饮料和零食的客观数据。饮料（如含糖碳酸/非碳酸软饮料、运动饮料等）和零食（如薯片、饼干等）数据按学校中可用单位数量、价格和自动售货机位置进行编码。使用R 3.2.3版本进行单变量和双变量分析。为了评估随时间推移的政策合规情况，将自动售货机中产品的营养信息与安大略省P/PM 150中规定的营养标准以及艾伯塔省《儿童和青少年营养指南（2012年）》中规定的标准进行了比较。
结果显示，随着时间的推移，自动售货机中销售含糖碳酸软饮料的学校比例下降（2012/2013年为9%，2014/2015年为3%），销售饼干的学校比例下降（26%对17%），销售蛋糕产品的学校比例下降（12%对5%），而销售薯片的学校比例变化不一致（三个学年分别为53%、67%和65%）。相反，结果突出显示在2012/2013学年和2014/2015学年之间，销售巧克力棒的自动售货机比例增加（7%对13%），销售饼干的自动售货机比例增加（21%对40%）。
大多数学校在自动售货机方面未遵守营养标准政策。需要对学校政策进行正式监测和评估，并提供信息和工具以支持营养政策的实施。
