To assess the impact of the quick-service restaurant industry (QSRI) self-regulatory initiative on fast-food advertising to children on Australian commercial television.
Analysis of advertisements for foods on the three main free-to-air commercial television channels (channels 7, 9 and 10) in Sydney, Australia, over 4 days in both May 2009 and April 2010 in terms of: number of advertisements; types of food (coded core [healthy] foods, non-core [unhealthy] foods, miscellaneous foods; or fast foods); whether advertised meals were intended for children; whether advertisements were broadcast during children's peak viewing times; and whether the company in question was a signatory to the QSRI initiative.
Change in the mean frequency and rate of food advertisements per hour from 2009 to 2010; change in the types of fast-food meals (healthier alternatives [at least one nutrient-dense, low-energy food considered part of a healthy diet for children], non-core [high in undesirable nutrients and not considered part of a healthy diet for children], and other) being advertised; and proportion of children's energy requirements provided by fast-food meals.
From 2009 to 2010, the mean frequency of fast-food advertisements increased from 1.1 to 1.5 per hour. While non-core fast foods comprised a lesser share of fast-food advertising in 2010 than 2009, the mean frequency at which they were advertised during times when the largest numbers of children were watching television remained the same (1.3 per hour in both 2009 and 2010). Family meals advertised for children's consumption in 2010 provided energy far in excess of children's requirements.
Children's exposure to unhealthy fast-food advertising has not changed following the introduction of self-regulation, and some fast foods advertised for children's consumption contain excessive energy. The limited impact of self-regulation suggests that governments should define the policy framework for regulating fast-food advertising to children.
评估快餐服务行业(QSRI)自律倡议对澳大利亚商业电视上儿童快餐广告的影响。
对澳大利亚悉尼的三个主要免费电视台(7 频道、9 频道和 10 频道)在 2009 年 5 月和 2010 年 4 月的四天内播出的食品广告进行分析,分析内容包括:广告数量;食品类型(编码核心[健康]食品、非核心[不健康]食品、杂项食品;或快餐);广告食品是否针对儿童;广告是否在儿童高峰收视时段播出;以及相关公司是否签署了 QSRI 倡议。
2009 年至 2010 年,每小时食品广告的平均频率和比率的变化;广告的快餐食品类型(更健康的选择[至少一种营养丰富、低能量的食物,被认为是儿童健康饮食的一部分]、非核心[含有不良营养且不被认为是儿童健康饮食的一部分]和其他)的变化;以及快餐食品提供的儿童能量需求比例。
从 2009 年到 2010 年,快餐广告的平均频率从每小时 1.1 次增加到 1.5 次。虽然 2010 年非核心快餐食品在快餐广告中的比例低于 2009 年,但在儿童观看人数最多的时段,它们的广告频率保持不变(2009 年和 2010 年每小时都为 1.3 次)。为儿童消费而宣传的家庭餐提供的能量远远超过儿童的需求。
引入自律措施后,儿童接触不健康快餐广告的情况并未改变,一些针对儿童消费的快餐食品含有过多的能量。自律措施的影响有限,表明政府应制定监管儿童快餐广告的政策框架。
