Restricting children's exposures to marketing of unhealthy foods and beverages is a global obesity prevention priority. Monitoring marketing exposures supports informed policymaking. This study presents a global overview of children's television advertising exposure to healthy and unhealthy products. Twenty-two countries contributed data, captured between 2008 and 2017. Advertisements were coded for the nature of foods and beverages, using the 2015 World Health Organization (WHO) Europe Nutrient Profile Model (should be permitted/not-permitted to be advertised). Peak viewing times were defined as the top five hour timeslots for children. On average, there were four times more advertisements for foods/beverages that should not be permitted than for permitted foods/beverages. The frequency of food/beverages advertisements that should not be permitted per hour was higher during peak viewing times compared with other times (P < 0.001). During peak viewing times, food and beverage advertisements that should not be permitted were higher in countries with industry self-regulatory programmes for responsible advertising compared with countries with no policies. Globally, children are exposed to a large volume of television advertisements for unhealthy foods and beverages, despite the implementation of food industry programmes. Governments should enact regulation to protect children from television advertising of unhealthy products that undermine their health.
限制儿童接触不健康食品和饮料的营销活动是全球预防肥胖的优先事项。监测营销活动有助于制定明智的政策。本研究概述了全球儿童电视广告对健康和不健康产品的接触情况。22 个国家提供了数据，数据采集时间为 2008 年至 2017 年。广告按照 2015 年世界卫生组织（世卫组织）欧洲营养成分模型（应允许/不允许做广告）对食品和饮料的性质进行了编码。高峰收视时段被定义为儿童前五个收视时段。平均而言，不允许做广告的食品/饮料广告数量是允许做广告的食品/饮料的四倍。与其他时段相比，高峰收视时段不允许的食品/饮料广告的频率更高（P<0.001）。在高峰收视时段，与没有政策的国家相比，有行业自律广告计划的国家的不允许的食品和饮料广告更多。尽管实施了食品行业负责任广告计划，但全球儿童仍大量接触到不健康食品和饮料的电视广告。政府应制定法规，保护儿童免受损害其健康的不健康产品的电视广告的影响。
