Exposure to food and non-alcoholic beverage advertisements (F&B ads) on television, which can affect children's nutrition knowledge, food consumption, diet quality, and purchasing preferences, is one aspect of the obesogenic environment. This aspect has been well-studied and assessed in many countries. In China, however, only few studies have been done in earlier years and all of them were focus on regular days. This study aimed to assess the extent and nature of F&B ads on television (TV) during the public holiday directed towards children aged 4-14 years in Beijing.
Top 3 channels viewed by children aged 4-14 years in Beijing were selected by TV viewership data, survey, and expert consultation. Each channel was recorded for 7 days (24 h) during the public holiday of the Chinese New Year in 2019. F&B ads were coded and analyzed following the adapted food promotion module of INFORMAS protocol. Three nutrient profile models were used to classify F&B ads as healthy or unhealthy F&B ads.
Of the 10,082 ads in 504-hour recorded programs, 42.9% were F&B ads. The hourly average ads and F&B ads per channel were 19.8 (SD 15.32) and 8.6 (SD 9.84), while that was higher on the national children's channel (17.15, SD 12.25) than other channels (p < 0.05). Of F&B ads classified with the three nutrient profile models, more than 55% were unhealthy for children. The categories most frequently advertised were savory snacks, milk drinks, nonpermitted milk drinks, cakes/sweet biscuits, and beverages. Unhealthy F&B ads were more likely to use promotional characters, brand benefit claims, and health claims than permitted F&B ads (p < 0.05).
Children in Beijing were exposed to a high proportion of unhealthy F&B ads during the Chinese New Year holiday. Our findings support the need to assess and regulate TV F&B ads marketing for children.
接触电视上的食品和非酒精饮料广告(F&B 广告)会影响儿童的营养知识、食物消费、饮食质量和购买偏好,这是肥胖环境的一个方面。许多国家都对这一方面进行了深入研究和评估。然而,在中国,早些年只有少数研究,而且都是针对普通日的。本研究旨在评估 2019 年中国春节期间北京面向 4-14 岁儿童的电视(TV)上 F&B 广告的数量和性质。
通过收视率调查、调查和专家咨询,选择北京 4-14 岁儿童收视率最高的 3 个频道。每个频道在 2019 年春节公共假期期间连续 7 天(24 小时)录制。根据 INFORMAS 协议的适应食品推广模块对 F&B 广告进行编码和分析。使用三种营养成分模型对 F&B 广告进行分类,分为健康 F&B 广告和不健康 F&B 广告。
在所记录的 504 小时的 10082 个广告中,有 42.9%是 F&B 广告。每小时平均广告和 F&B 广告数量分别为 19.8(SD 15.32)和 8.6(SD 9.84),而国家儿童频道(17.15,SD 12.25)的广告数量高于其他频道(p<0.05)。根据三种营养成分模型分类的 F&B 广告中,超过 55%的广告对儿童不健康。广告宣传最频繁的类别是咸味零食、牛奶饮料、未获准的牛奶饮料、蛋糕/甜饼干和饮料。与允许的 F&B 广告相比,不健康的 F&B 广告更有可能使用促销人物、品牌利益声明和健康声明(p<0.05)。
在北京,儿童在春节假期期间接触到大量不健康的 F&B 广告。我们的研究结果支持对儿童电视 F&B 广告营销进行评估和监管的必要性。
