To quantify food/beverage advertising on television in Montreal (Quebec), to estimate and characterise children's exposure and to examine trends over time.
Television food advertising data were licensed for nineteen food categories and eighteen stations for May 2011, 2016 and 2019. The frequency of advertisements and the average number viewed per child aged 2-11 years overall, by food category and by station type (i.e. youth-appealing (n 3) and generalist (n 15) stations) were determined. The percent change in advertising frequency and exposure between May 2011 and 2019 was calculated.
Montreal, Quebec, Canada.
This study used media data and did not directly involve human participants.
The total number of television advertisements increased by 11 % between May 2011 (n 41 084) and May 2019 (n 45 406); however, exposure to food/beverage advertisements decreased by 53 %, going from 226 ads/child in May 2011 to 107 ads/child in May 2019. Overall, the most advertised food categories in both May 2011 and 2019 were fast food (29·8 % and 39·2 %, respectively) followed by chocolate (14·2 %) in 2011 and savory snacks (9·7 %) in 2019. In May 2019, children were predominantly exposed to unhealthy food categories such as fast food (41·3 % of exposure), savory snacks (7·5 %), chocolate (5·0 %) and regular soft drinks (4·5 %), and most (89·3 %) of their total exposure occurred on generalist television stations.
Despite Quebec's restrictions on commercial advertising directed to children under 13 years, Quebecois children are still frequently exposed to unhealthy food advertising on television. Government should tighten restrictions to protect children from this exposure.
量化蒙特利尔(魁北克省)电视上的食品/饮料广告,估计和描述儿童的暴露情况,并考察随时间的变化趋势。
为 2011 年 5 月、2016 年 5 月和 2019 年 5 月,购买了 19 个食品类别和 18 个电视台的电视食品广告数据。确定了所有 2-11 岁儿童的广告频率和平均观看次数,按食品类别和电视台类型(即针对年轻人的(n=3)和综合的(n=15)电视台)进行了划分。计算了 2011 年 5 月至 2019 年广告频率和暴露量的百分比变化。
加拿大魁北克省蒙特利尔。
本研究使用了媒体数据,并未直接涉及人类参与者。
2011 年 5 月(n=41484)和 2019 年 5 月(n=45406)之间,电视广告总数增加了 11%;然而,食品/饮料广告的暴露量减少了 53%,从 2011 年 5 月的每个儿童 226 个广告减少到 2019 年 5 月的 107 个广告。总体而言,2011 年和 2019 年广告最多的食品类别均为快餐(分别为 29.8%和 39.2%),其次是巧克力(14.2%)和2011 年的咸味小吃(9.7%)和 2019 年的咸味小吃(9.7%)。2019 年 5 月,儿童主要接触到快餐(41.3%的暴露)、咸味小吃(7.5%)、巧克力(5.0%)和普通软饮料(4.5%)等不健康食品类别,并且他们的总暴露量中(89.3%)大部分发生在综合电视台。
尽管魁北克省对 13 岁以下儿童的商业广告有限制,但魁北克儿童仍经常在电视上接触到不健康的食品广告。政府应加强限制,以保护儿童免受这种暴露。
