Conducting systematic literature review of Front-of-Pack-Labelling: integrative framework, themes formation, and path for future research

Abstract

Purpose The escalating prevalence of non-communicable diseases has underscored the crucial role of Front-of-Pack-Labelling (FoPL) in shaping consumer decisions. However, the research in this field is still in its developing stage, leading to a fragmented and limited body of work. Given the critical importance of FoPL, it is imperative to conduct a comprehensive literature review of existing research to outline the academic aspect of FoPL research. This research paper aims to combine the available research to generate a systematic compilation of literature, thereby contributing to the advancement of knowledge in this vital area. Design/methodology/approach To achieve the objectives, a systematic literature review technique was followed. The database used for the extraction of documents was Scopus. Sixty-three articles were critically examined to extract the relevant information. Findings Based on the analysis types of a study conducted, data collection source, types of FoPL studied, key themes, theoretical model, antecedents, dependent/independent variables and outcome were identified. It also explained the underlying phenomenon of FoPL’s impact on the various outcomes. An integrative theoretical model was also proposed based on the underlying mechanism, antecedents, moderator, mediator and outcome. Towards the end of the paper, research gaps were also identified for future paths in unexplored areas. Originality/value To the best of the authors’ knowledge, this paper is the first attempt in the field of FoPL to comprehensively include all the dependent and independent variables involved and propose a framework along with future research prospects. The findings will guide researchers and policymakers.
