Food and non\u2010alcoholic 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\u2010analysis examined the evidence (quantitative or mixed\u2010method) for a relationship between exposure to digital game\u2010based or influencer food marketing, and food\u2010related (brand awareness, attitudes, preferences, purchase, and consumption), and post\u2010consumption (weight, body mass index [BMI], and dental caries) outcomes in young people (\u226418\u2009years). Twenty\u2010three databases were searched in March 2021. Twenty\u2010two studies met the inclusion criteria, of which 20 were included in the quantitative synthesis. Meta\u2010analyses indicated food marketing was associated with more positive attitudes and greater preferences (OR\u2009=\u20091.74,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001 [95%CI: 1.355, 2.232]), and increased consumption (SMD\u2009=\u20090.37,\n                    <jats:italic>p<\/jats:italic>\n                    \u2009&lt;\u20090.001 [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\u2010related outcomes. This is the first quantitative synthesis to demonstrate these relationships; this work has implications for food marketing policy.\n                  <\/jats:p>","DOI":"10.1111\/obr.13630","type":"journal-article","created":{"date-parts":[[2023,8,23]],"date-time":"2023-08-23T02:02:00Z","timestamp":1692756120000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":30,"title":["A systematic review and meta\u2010analysis of the effect of digital game\u2010based or influencer food and non\u2010alcoholic beverage marketing on children and adolescents: Exploring hierarchy of effects outcomes"],"prefix":"10.1111","volume":"24","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8894-5938","authenticated-orcid":false,"given":"Rebecca K.","family":"Evans","sequence":"first","affiliation":[{"name":"Department of Psychology The University of Liverpool  Liverpool UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Paul","family":"Christiansen","sequence":"additional","affiliation":[{"name":"Department of Psychology The University of Liverpool  Liverpool UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Amy","family":"Finlay","sequence":"additional","affiliation":[{"name":"Department of Psychology The University of Liverpool  Liverpool UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Andrew","family":"Jones","sequence":"additional","affiliation":[{"name":"School of Psychology Liverpool John Moores University  Liverpool UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Michelle","family":"Maden","sequence":"additional","affiliation":[{"name":"Liverpool Reviews and Implementation Group, Institute of Population Health The University of Liverpool  Liverpool UK"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8384-4994","authenticated-orcid":false,"given":"Emma","family":"Boyland","sequence":"additional","affiliation":[{"name":"Department of Psychology The University of Liverpool  Liverpool UK"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2023,8,22]]},"reference":[{"key":"e_1_2_9_2_1","unstructured":"WHO.Obesity and overweight. 9 June 2021.
