Revisiting 42 Years of literature on food marketing to children: A morphological analysis

Despite the preventive measures taken by the WHO, childhood obesity is still on the rise and is expected to increase by 100% between 2020 and 2035. Food marketing continues to permeate children's environments in numerous ways and influence the food behaviour of children, thus significantly contributing to the rise of obesity. Studies suggest that the literature on the effects of food marketing on children is complex and multidimensional. To fully understand these effects, a comprehensive and systematic approach is required. Nonetheless, existing reviews have focused only on specific aspects and have not comprehensively covered the literature on food marketing to children. Therefore, this review aims to navigate potential research gaps in the existing literature through a comprehensive examination of the literature by using morphological analysis (MA) methodology, the first time in this domain. Using PRISMA, 202 papers were considered eligible for inclusion and further analysed using MA. The articles were categorised into three dimensions to develop the MA framework: Stimuli (Food well-being), Organism, and Response, and 34 variants. The review has presented future research prospects by identifying at least 218 research gaps. With these findings, researchers can further explore the gaps and develop new research questions that could foster an understanding of the multifarious literature. Moreover, these findings can also provide marketers and practitioners with a better comprehension of the current state of the literature and develop more effective strategies for responsible marketing practices and policies.
