背景不健康的食品营销是儿童不健康饮食和肥胖的一个强有力的决定因素。尽管众所周知，食品营销人员在社交媒体上针对年轻人，还没有研究量化儿童在这些平台上的暴露。ObjectivesTo比较儿童和青少年在社交媒体应用程序上看到的食品营销的频率和健康程度，并估计他们的每周消费量。（7- 16岁）完成了一项关于他们媒体使用的调查，并在他们通常使用的移动终端上使用他们最喜欢的两个社交媒体应用程序进行了5分钟的记录。应用程序的使用记录进行了审查，以确定食品营销exposs.ResultsOverall，72%的参与者暴露于食品营销。在确定的215个食品营销曝光中，大多数推销不健康的产品，如快餐（44%）和含糖饮料（9%）。与儿童相比，青少年平均每10分钟观看更多的食品营销实例（平均值[SD]=2.6 [2.7] vs 1.4 [2.1]，U=1606，z=2.94，P=0.003）。据估计，儿童和青少年看到食品营销30和189次，平均每周在社交媒体apps上，respectively.ConclusionsStatutory法规限制不健康的食品营销，以青少年和儿童在社交媒体上应予以考虑。
BackgroundUnhealthy food marketing is a powerful determinant of unhealthy diets and obesity among children. Although it is known that food marketers target young people on social media, no study has yet quantified children's exposure on these platforms.ObjectivesTo compare the frequency and healthfulness of food marketing seen by children and adolescents on social media apps as well as estimate their weekly exposure.Methods101 children and adolescents (ages 7-16years) completed a survey on their media use and were recorded using their two favourite social media apps for 5minutes each on the mobile device they usually use. Recordings of app use were reviewed to identify food marketing exposures.ResultsOverall, 72% of participants were exposed to food marketing. Of the 215 food marketing exposures identified, most promoted unhealthy products such as fast food (44%) and sugar-sweetened beverages (9%). Adolescents viewed more instances of food marketing, on average, per 10-minute period compared with children (Mean [SD]=2.6 [2.7] versus 1.4 [2.1], U=1606, z=2.94, P=0.003). It was also estimated that children and adolescents see food marketing 30 and 189 times on average per week on social media apps, respectively.ConclusionsStatutory regulations restricting unhealthy food marketing to adolescents and children on social media should be considered.
