Tijdschriftbijdrage - Tijdschriftartikel

The media marketing's effect on child and adult eating has been extensivelyresearched, yet, little is known about its effect on adolescents. The aim of this reviewis to synthesize available research on the relation between media food marketing andeating‐related cognitions, attitudes, and behaviors among pre‐adolescents (8‐11) andadolescents (12‐19). We systematically screened and retrieved 9324 articles, ofwhich 28 were included in the review‐analysis and 19 in the meta‐analysis. Robustvariance estimation with random effect weights indicated a positive small standardeffect size (d= 0.26,P< .001) of media food marketing on all unhealthy eating out-comes, and a subgroup analysis revealed a small effect size (d= 0.26,P< .001) onunhealthy eating behaviors specifically. Another subgroup analysis among adoles-cents revealed an effect of marketing (d= 0.22,P< .05) on unhealthy eating out-comes. This review demonstrates the significance of media marketing on eating inpre‐adolescents and adolescents, and highlights limitations in the food marketingand adolescent eating literature specific to eating outcomes and marketing mediastudied and research designs utilized. We call for properly designed food marketingresearch exploring digital media's effect on eating attitudes and cognitions, especiallyamong older adolescents.
