To examine the efficacy of self-regulation of food marketing to children by comparing, during children's preferred viewing on television, the differences in food/beverage marketing between two groups of corporations: 17 corporations participating in the Canadian Children's Food and Beverage Advertising Initiative (CAI) and 35 corporations not participating (non-CAI) in this initiative.
The food/beverage marketing activities of CAI and non-CAI corporations during 99.5 hours of children's preferred viewing on television were compared. First, the preferred television viewing of 272 children aged 10-12 years from Ontario and Quebec who completed TV viewing journals for a seven-day period was determined. A total of 32 television stations were simultaneously recorded, and a content analysis of children's preferred viewing was conducted and included coding all food/beverage promotions and their nutritional content. Each food/beverage promotion was classified by corporation type (i.e., CAI or non-CAI).
The CAI was responsible for significantly more food/beverage promotions, and used media characters and repetition more frequently in their food/beverage promotions than the non-CAI group. Nutritionally, the CAI food/beverage promotions were higher in fats, sugar, sodium and energy per 100 grams. A significantly greater proportion of the CAI food/beverage promotions were considered 'less healthy' compared to the non-CAI promotions.
With the exception of the four corporations that did not market to children at all, the commitments that have been made in the CAI are not having a significant impact on the food and beverage marketing environment on television which is viewed by 10-12-year-olds.
通过比较两组公司在儿童偏好的电视节目时段的食品/饮料营销差异,研究食品营销自我监管对儿童的效果。这两组公司分别为:17家参与加拿大儿童食品和饮料广告倡议(CAI)的公司,以及35家未参与(非CAI)该倡议的公司。
比较了CAI公司和非CAI公司在99.5小时儿童偏好的电视节目时段内的食品/饮料营销活动。首先,确定了安大略省和魁北克省272名10至12岁儿童的偏好电视节目,这些儿童完成了为期七天的电视观看日志。同时录制了32个电视台,并对儿童偏好的节目进行了内容分析,包括对所有食品/饮料促销活动及其营养成分进行编码。每个食品/饮料促销活动按公司类型(即CAI或非CAI)进行分类。
与非CAI组相比,CAI公司的食品/饮料促销活动显著更多,并且在食品/饮料促销中更频繁地使用媒体角色和重复宣传。在营养方面,CAI公司的食品/饮料促销产品每100克的脂肪、糖、钠和能量含量更高。与非CAI促销产品相比,CAI公司的食品/饮料促销产品中被认为“不太健康 ”的比例显著更高。
除了四家完全不向儿童进行营销的公司外,CAI所做出的承诺对10至12岁儿童观看的电视上的食品和饮料营销环境没有产生重大影响。
