We aimed to determine the frequency and content of television food advertisements during children's viewing times on various New Zealand television channels.
A content analysis was conducted of two free-to-air channels covering a total of 155 h of television time during children's viewing times (n = 858 food advertisements in 2005). Comparisons were made with data from 1997 and data from Australia.
Compared to Australian channels, both New Zealand channels (TV3 and TV2) had significantly higher proportions of food advertisements that were classified as being "high in fat and/or sugar" (54% versus 80% and 69%, respectively). Using a more detailed classification system, 70.3% of food advertisements on the New Zealand channels were for foods "counter to improved nutrition" (95% CI: 67.1%, 73.3%) compared to those "favoring improved nutrition" at 5.1% (95% CI: 3.8%, 6.9%). The number of food advertisements per hour was higher in 2005 than in 1997 for the channel (TV2) for which there was time trend data (12.8 versus 8.0 per hour for the afternoon time slot).
These findings provide further evidence that the majority of food advertising on New Zealand television is counter to nutritional guidelines. They suggest the need for further regulatory or other controls.
我们旨在确定新西兰各电视频道儿童收视时段电视食品广告的频率和内容。
对两个免费电视频道进行了内容分析，涵盖儿童收视时段总计155小时的电视节目时间（2005年有858条食品广告）。并与1997年的数据以及澳大利亚的数据进行了比较。
与澳大利亚频道相比，新西兰的两个频道（TV3和TV2）中被归类为“高脂肪和/或高糖”的食品广告比例显著更高（分别为54%、80%和69%）。使用更详细的分类系统，新西兰频道上70.3%的食品广告宣传的是“不利于改善营养”的食品（95%置信区间：67.1%，73.3%），而宣传“有利于改善营养”食品的广告占5.1%（95%置信区间：3.8%，6.9%）。对于有时间趋势数据的频道（TV2），2005年每小时的食品广告数量高于1997年（下午时段每小时分别为12.8条和8.0条）。
这些发现进一步证明，新西兰电视上的大多数食品广告与营养指南相悖。这表明需要进一步的监管或其他控制措施。
