Abstract

IMPORTANCE

Reducing children's exposure to advertisements promoting unhealthy foods and beverages has been recognized by the World Health Organization as a key strategy to improve children's diets and reduce childhood obesity.

OBJECTIVE

To examine changes in children's exposure to food-related (food, beverage, and restaurant) television advertising, including for products high in nutrients to limit (NTL; ie, saturated fat, trans fat, total sugars, and sodium) based on federal Interagency Working Group guidelines, following changes in the voluntary industry self-regulatory Children's Food and Beverage Advertising Initiative (CFBAI).

DESIGN, SETTING, AND PARTICIPANTS: This repeated cross-sectional study used US television ratings data on advertising exposure from The Nielsen Company for 2013, 2014, 2015, 2018, and 2022. Food and beverage product advertisements were assessed for nutritional content. Participants included 2- to 5-year-old and 6-to 11-year-old children. Data analysis was performed from July 2023 to January 2024.

EXPOSURE

Changes in CFBAI standards in 2014 and 2020.

MAIN OUTCOMES AND MEASURES

The primary outcome was the number of food-related advertisements seen per year and percentage of food and beverage product advertisements high in NTL, on all programming and children's programming (defined as ≥35% child audience share).

RESULTS

From 2013 to 2022, total advertisements seen per year declined by 77.6% (from 4611 to 1035) for 2- to 5-year-olds and by 78.5% (from 4860 to 1046) for 6- to 11-year-olds. Advertisements seen on children's programming decreased by 95.1% (from 1703 to 84 per year) for 2- to 5-year-olds and by 97.0% (from 1745 to 52 per year) for 6- to 11-year-olds. The percentages of advertisements for products high in NTL decreased from 2013 to 2022 but were still high: 68.9% for all programming and 63.9% for children's programming for 2- to 5-year-olds, and 68.4% for all programming and 60.6% for children's programming for 6- to 11-year-olds. The majority (51%-52%) of CFBAI-member food and beverage advertisements on children's programming remained high in NTL. Black children saw more food-related television advertisements than White children (58% more for 2- to 5-year-olds and 72% more for 6- to 11-year-olds); however, the percentage of advertisements for food and beverage products high in NTL seen was similar by race.

CONCLUSIONS AND RELEVANCE

In this repeated cross-sectional study of children's exposure to food-related television advertisements, exposure via children's programming decreased substantially. However, most advertisements seen were still for unhealthy products, and exposure from all programming remained substantial. Findings of more than 90% of advertising exposure not from children's programming and more than 1000 food-related advertisements seen per year suggest the need for government regulations based on time of day rather than programming.

摘要

重要性

世界卫生组织已经认识到,减少儿童接触宣传不健康食品和饮料的广告是改善儿童饮食和减少儿童肥胖的关键策略。

目的

根据联邦机构间工作组的指导方针,检查儿童接触食品相关(食品、饮料和餐厅)电视广告的变化,包括基于营养限制的产品(即饱和脂肪、反式脂肪、总糖和钠),这些变化是在儿童食品和饮料广告倡议(CFBAI)的自愿行业自律措施发生变化后进行的。

设计、地点和参与者:这是一项重复的横断面研究,使用了尼尔森公司的美国电视收视率数据,以评估 2013 年、2014 年、2015 年、2018 年和 2022 年的广告曝光情况。评估了食品和饮料产品广告的营养成分。参与者包括 2 至 5 岁和 6 至 11 岁的儿童。数据分析于 2023 年 7 月至 2024 年 1 月进行。

暴露情况

2014 年和 2020 年 CFBAI 标准的变化。

主要结果和措施

主要结果是每年看到的食品相关广告数量和营养限制产品(即饱和脂肪、反式脂肪、总糖和钠)的食品和饮料产品广告的百分比,所有节目和儿童节目(定义为≥35%的儿童观众份额)。

结果

从 2013 年到 2022 年,2 至 5 岁儿童每年看到的广告总数下降了 77.6%(从 4611 降至 1035),6 至 11 岁儿童下降了 78.5%(从 4860 降至 1046)。儿童节目中的广告数量减少了 95.1%(从 1703 降至每年 84 条),2 至 5 岁儿童减少了 97.0%(从 1745 降至每年 52 条)。高营养限制产品的广告百分比从 2013 年到 2022 年有所下降,但仍然很高:2 至 5 岁儿童所有节目和儿童节目中为 68.9%,6 至 11 岁儿童所有节目和儿童节目中为 63.9%。CFBAI 成员在儿童节目中的大部分(51%-52%)食品和饮料广告仍然高营养限制。黑人儿童比白人儿童看到更多的食品相关电视广告(2 至 5 岁儿童多 58%,6 至 11 岁儿童多 72%);然而,种族之间看到的营养限制食品和饮料产品广告的百分比相似。

结论和相关性

在这项对儿童接触食品相关电视广告的重复横断面研究中,儿童节目中的广告曝光量大幅下降。然而,大多数广告仍然是不健康产品,所有节目中的广告曝光量仍然很大。超过 90%的广告曝光不是来自儿童节目,每年有超过 1000 条食品相关广告的发现表明,需要根据时间而不是节目制定政府法规。
