Abstract

Background

Food and beverage marketing drives poor diet quality and obesity risk among children. However, it is unknown how much young children are exposed to digital food and beverage marketing on mobile devices like tablets and smartphones.

Objectives

The objective of this study was to estimate how frequently young children, who are particularly vulnerable to advertising, view food and beverage marketing while using mobile devices.

Methods

Seventy-five 2–11-y olds and their parents from Massachusetts participated in this cross-sectional study from 2022 to 2023. Average estimated exposure to food and beverage advertisements and food/beverage brand appearances was calculated for 5 consecutive days using a combination of battery screenshots and average estimates of marketing collected from children’s devices. Generalized estimating equations tested for sociodemographic differences in advertising exposure.

Results

Young children’s estimated exposure to food and beverage advertisements and brand appearances on mobile devices was highly variable, with many children seeing none on a given day but a substantial minority viewing large amounts. Estimated exposure depended on how much a child used either YouTube or a gaming app; there was no exposure on other apps used by children. Higher parental educational attainment was associated with substantially reduced risk of a child viewing 2 or more food or beverage advertisements or brand appearances on a given day (adjusted odds ratio = 0.26, 95% confidence interval: 0.10, 0.70).

Conclusions

Certain children, particularly those from households with lower parental educational attainment, may be at risk for high exposure to digital food and beverage marketing, whereas other children may have minimal risk. Future research should explore exposure in more diverse samples with valid, feasible measures.
估算幼儿在移动设备上接触食品和饮料营销的情况
背景食品和饮料营销导致儿童饮食质量低下和肥胖风险增加。本研究的目的是估计特别容易受到广告影响的幼儿在使用移动设备时观看食品和饮料营销的频率。方法来自马萨诸塞州的 75 名 2-11 岁的儿童及其父母参加了 2022 年至 2023 年的横断面研究。利用电池截图和从儿童设备中收集的营销平均估计值,计算出连续 5 天的食品和饮料广告以及食品/饮料品牌出现的平均估计曝光量。结果青少年儿童对移动设备上食品饮料广告和品牌出现的估计接触量变化很大,许多儿童在某一天没有看到任何广告,但也有相当一部分儿童看到了大量广告。估计的接触率取决于儿童使用YouTube或游戏应用程序的程度;儿童使用的其他应用程序则没有接触率。结论某些儿童,特别是那些来自父母教育程度较低家庭的儿童,可能会有大量接触数字食品和饮料营销的风险,而其他儿童的风险可能很小。未来的研究应采用有效、可行的测量方法,在更多样化的样本中探索儿童接触数字食品和饮料营销的情况。
