"It's Just Addictive People That Make Addictive Videos": Children's Understanding of and Attitudes Towards Influencer Marketing of Food and Beverages by YouTube Video Bloggers.

Exposure to influencer marketing of foods and beverages high in fat, sugar, and/or salt (HFSS) increases children's immediate intake. This study qualitatively explored children's understanding of, and attitudes towards, this marketing, to elucidate potential mechanisms through which exposure affects behavior. In six focus groups (n = 4) children (10-11 years) were shown a YouTube video featuring influencer marketing of an HFSS product. Inductive thematic analysis identified six themes from children's discussions of this marketing: (1) YouTubers fill a gap in children's lives, (2) the accessibility of YouTubers increases children's understanding of their actions, (3) influencer marketing impacts all-the influencer, the brand, and the viewer, (4) attitudes towards influencer marketing are most affected by a YouTuber's familiarity, (5) YouTuber influencer marketing is effective because they are not 'strangers', (6) children feel able to resist influencer marketing of HFSS products. Children had an understanding of the persuasive intent of this marketing, and although most were sceptical, familiar YouTubers elicited particularly sympathetic attitudes. Children felt affected by influencer marketing of HFSS products, but believed they were able to resist it. Beyond theoretical insight, this study adds to the growing body of evidence to suggest children's exposure to HFSS influencer marketing should be reduced.

The effect of influencer marketing of food and a "protective" advertising disclosure on children's food intake.

BACKGROUND: Children are active on social media and consequently are exposed to new and subtle forms of food marketing. OBJECTIVES: To examine whether exposure to a YouTube video featuring influencer marketing of an unhealthy snack affects children's ad libitum snack intake and whether inclusion of an advertising disclosure moderates this effect. METHODS: In a randomized between-subjects design, 151 children (aged 9-11 y; mean, 10.32 y ± 0.6) were exposed to influencer marketing of a non-food product (n = 51), or an unhealthy snack with (n = 50) or without (n = 50) an advertising disclosure. Participants' ad libitum intake of the marketed snack and an alternative brand of the same snack was measured. RESULTS: Children exposed to food marketing with (P < .001, d = 1.40) and without (P < .001, d = 1.07) a disclosure consumed more (kcals) of the marketed snack relative to the alternative; the control did not differ (.186, d = 0.45). Consumption of the alterative brand did not differ across conditions (.287, ηp2 = .02). Children who viewed food marketing with a disclosure (and not those without) consumed 41% more of the marketed snack (.004, ηp2 = .06), compared with control. CONCLUSIONS: Influencer marketing increases children's immediate intake of the promoted snack relative to an alternative brand. Advertising disclosures may enhance the effect.
