The report updates three previous systematic reviews of the nature, extent and effects of food promotion to children The Hastings et al., 2003 review, undertaken for the United Kingdom Food Standards Agency (FSA), was the first ever systematic study of the effects of food promotion on children. The McDermott et al. 2004 systematic review was commissioned by (WHO) to broaden the evidence base and examine studies on the effects of food marketing to children in developing countries. Finally, the Hastings et al. 2006 review was produced for WHO as a Technical Paper in preparation for the WHO forum and technical meeting of stakeholders on ‘Marketing food and non-alcoholic beverages to children’, held in Oslo (May 2006).
