简介：通过社交媒体进行与食品相关的品牌推广是一种越来越重要的针对青年的营销策略，但人们对青少年如何在网上与这些品牌互动知之甚少。这项研究测量了青少年对食品/饮料品牌的社交媒体参与度，参与度的社会人口统计学差异，以及参与度和屏幕时间之间的关系。美国青少年的横断面在线调查（13-17岁，N= 1564），非西班牙裔黑人和西班牙裔的过采样（更多和更少的文化适应）参与者，评估餐馆，食品和饮料品牌曾经喜欢，分享，或在社交媒体上关注。多变量逻辑回归模型研究品牌参与，社会人口变量（种族/民族，文化适应，年龄，性别和父母教育）和屏幕时间（电视和其他屏幕）之间的关联。结果：70%的青少年报告参与任何食品/饮料品牌在社交媒体上（范围从1到48），35%参与5 +品牌。非西班牙裔黑人和文化适应程度较低的西班牙裔青少年比非西班牙裔白色青少年更有可能与品牌接触。大约一半的参与者表示他们与快餐品牌（54%），含糖饮料（50%），糖果（46%）和零食（45%）有关，而只有7%的人表示他们与所有其他类别的食品/饮料品牌有关。每天看电视超过2小时与任何品牌的参与;而每天使用其他屏幕超过2小时与以下5 + brands.Conclusions：在社交媒体上与不健康食品品牌的参与在青少年中很常见。非西班牙裔黑人和文化适应程度较低的西班牙裔青年的不成比例的参与引起了更多的关注。需要进行研究，以了解这种营销如何影响青少年的食物偏好，饮食和健康。
Introduction: Food-related promotion of brands via social media represents an increasingly important youth-targeted marketing strategy, but little is known about how adolescents interact with these brands online. This study measures adolescents' social media engagement with food/beverage brands, sociodemographic differences in level of engagement, and relationships between engagement and screen time.Methods: Cross-sectional online survey of US adolescents (ages 13-17, N= 1564), oversampled for non-Hispanic Black and Hispanic (more- and less-acculturated) participants, assessed restaurant, food, and beverage brands ever liked, shared, or followed of on social media. Multivariate logistic regression models examined associations between brand engagement, sociodemographic variables (race/ethnicity, acculturation, age, gender, and parent education), and screen time (TV and other screens).Results: Seventy percent of adolescents reported engaging with any food/beverage brands on social media (ranging from 1 to 48), and 35% engaged with 5 + brands. Non-Hispanic Black and less-acculturated Hispanic adolescents were more likely than non-Hispanic White adolescents to engage with brands. Approximately one-half reported engaging with brands of fast food (54% of participants), sugary drinks (50%), candy (46%), and snacks (45%), while just 7% reported engaging with all other categories of food/beverage brands. Watching TV more than 2 h-per-day was associated with any brand engagement; while using other screens more than 2 h-per-day was associated with following 5 + brands.Conclusions: Engagement with unhealthy food brands on social media is common among adolescents. Disproportionate engagement by non-Hispanic Black and less-acculturated Hispanic youth raises additional concerns. Research is needed to understand how such marketing affects adolescents' food preferences, diets, and health.
