To study changes in food advertising on television after Chile's food marketing restriction was implemented in June 2016. Food advertisements shown between 6 am and 12 am on the 4 primary broadcast and 4 cable channels with the largest Chilean youth audiences during 2 random weeks in April and May 2016 and 2017 were analyzed for product nutrition and child-directed marketing. The percentage of ads for foods high in energy, saturated fats, sugars, or sodium (HEFSS) decreased from 41.9% before the regulation to 14.8% after the regulation ( < .001). This decrease occurred in programs intended for children (from 49.7% to 12.7%; < .001) as well as general audiences (from 38.5% to 15.7%; < .001). The largest declines were seen for sodas, desserts, breakfast cereals and industrialized fruit- and vegetable-flavored drinks. Fewer HEFSS ads featured child-directed content (a decrease from 44.0% to 12.0%; < .001), and the remaining child-directed HEFSS ads primarily aired on internationally owned cable channels. The significant postregulation decrease in the prevalence of HEFSS television ads suggests that children in Chile are now less exposed to unhealthy food advertising. However, television originating from national and international outlets should still be monitored for compliance.
研究智利 2016 年 6 月实施食品营销限制后，电视食品广告的变化。在 2016 年 4 月和 2017 年 5 月的两个随机周内，分析了在早上 6 点至 12 点之间播出的 4 个主要广播频道和 4 个拥有最大智利青年观众的有线电视频道上的食品广告，以研究产品营养和面向儿童的营销情况。高能量、饱和脂肪、糖或钠（HEFSS）食品广告的比例从监管前的 41.9%下降到监管后的 14.8%（ < .001）。这种下降不仅发生在针对儿童的节目中（从 49.7%降至 12.7%； < .001），也发生在一般受众的节目中（从 38.5%降至 15.7%； < .001）。降幅最大的是苏打水、甜点、早餐麦片和工业化水果味及蔬菜味饮料。面向儿童的 HEFSS 广告的儿童导向内容减少（从 44.0%降至 12.0%； < .001），而其余面向儿童的 HEFSS 广告主要在国际拥有的有线电视频道播出。监管后 HEFSS 电视广告的流行率显著下降表明，智利儿童现在接触到的不健康食品广告减少了。然而，仍应监测来自国内和国际渠道的电视节目，以确保其合规性。
