Nigerian adolescents' exposure to fast food marketing via Instagram.

OBJECTIVES: To explore the promotion of fast food to lower-income adolescents on Instagram with the specific aims of (i) identifying the marketing strategies used by fast food brands on Instagram to promote fast food to Nigerian adolescents and (ii) examining the influence of these strategies on user engagement. DESIGN: A content analysis of posts from a 90-day period of the Instagram accounts of five fast-food brands in Nigeria was conducted. Overall, 576 posts were analysed, using a codebook developed based on the relevant literature, to identify adolescent-targeted strategies. User engagement was measured by number of likes each post received. RESULTS: The observed brands frequently utilised adolescent-targeted marketing strategies, with the most popular strategies being emotional appeal, 'teen language' and product appeal. The results of Mann-Whitney U tests revealed significant associations between the use of these promotional strategies and user engagement. Adolescent-aimed strategies like product appeal and competitions resulted in higher user engagement with fast food promotional content. CONCLUSION: Fast food companies heavily target lower income adolescents through the use of Instagram. This raises health concerns related to the consumption of unhealthy food that arises from regular advertising in that demographic. Further, this exposure increases ad interactions that could cause adolescents to view fast foods more positively. Overall, findings indicate the need for actions aiming to limit and reduce the effect of adolescents' exposure to fast food marketing on social media, to target the features of social media platforms which affords users the ability to interact with fast food advertisements.

A systematic review of the adolescent-directed marketing strategies of transnational fast food companies in low- and middle-income countries.

Introduction: Fast food consumption is associated with excessive intake of energy-dense foods; a major determinant of childhood obesity. The lack of data on the marketing strategies used to promote fast food to adolescents in low and middle-income countries (LMICs) acts as a barrier to global efforts to reduce the marketing of unhealthy foods to young people around the world. Objectives: This systematic review aimed to identify the adolescent-directed marketing strategies of transnational fast food corporations in LMICs. Methods: A systematic search of eight scientific databases (PubMed, CINAHL, Medline, Embase, ProQuest, PsycInfo, Scopus and Google Scholar) was conducted. Following PRISMA guidelines, primary research articles written in English were included if they were published between 1 January 2010 and 30 December 2022, and reported any adolescent-directed marketing activity undertaken by a transnational fast food company operating in a LMIC. Articles were excluded if they were not peer reviewed. The quality of the included articles was assessed using a condensed version of the Consolidated Criteria for Reporting Qualitative Research tool. Results: Twelve articles met the eligibility criteria and were included in this review. A narrative synthesis of these articles revealed that the most documented strategies used to promote fast food to adolescents in LMICs were the use of incentives or premium offers, product appeals, promotional characters and brand familiarity. These strategies were mostly observed on social media, suggesting that there are serious concerns about adolescent exposure to fast food via social media in developing settings, especially as contextual differences in the nature of such marketing were identified. Discussion: The promotion of fast food to adolescents in LMICs is contextual in nature, with the nature of marketing strategies employed by transnational fast food corporations varying greatly across cultural and socio-economic contexts. These findings are crucial for the development of guidelines and regulations restricting the marketing of fast food to adolescents in lower income settings, contributing to global efforts to reduce adolescent exposure to unhealthy food promotion.
