Abstract
Videogame livestreaming platforms are an emerging form of digital media, popular with young people, where users watch gaming influencers play videogames. Food and non-alcoholic beverage (hereafter: food) brands have a substantial presence on these platforms, yet no studies have examined the impact of this food marketing on young people. This systematic review and meta-analysis examined the evidence (quantitative or mixed-method) for a relationship between exposure to digital game-based or influencer food marketing, and food-related (brand awareness, attitudes, preferences, purchase, and consumption), and post-consumption (weight, body mass index [BMI], and dental caries) outcomes in young people (≤18 years). Twenty-three databases were searched in March 2021. Twenty-two studies met the inclusion criteria, of which 20 were included in the quantitative synthesis. Meta-analyses indicated food marketing was associated with more positive attitudes and greater preferences (OR = 1.74, p < 0.001 [95%CI: 1.355, 2.232]), and increased consumption (SMD = 0.37, p < 0.001 [95%CI: 0.219, 0.529]). Narrative synthesis indicated that food marketing may increase brand awareness but not pester intent, although data were limited. Evidence suggests that there is a relationship between exposure to food marketing via influencers and digital gaming media, and several food-related outcomes. This is the first quantitative synthesis to demonstrate these relationships; this work has implications for food marketing policy.
