Differential exposure to, and potential impact of, unhealthy advertising to children by socio-economic and ethnic groups: A systematic review of the evidence

Differential exposure to, and potential impact of, unhealthy advertising to children by socio-economic and ethnic groups: A systematic review of the evidence

This systematic review examines the differential potential exposure and impact of unhealthy food advertising to children according to socio-economic position (SEP) and/or ethnicity. 

Most studies (n = 19) revealed a higher potential exposure or a greater potential impact of unhealthy food advertising among ethnic minority or lower SEP children. Few studies reported no difference (n = 3) or mixed findings (n = 3). Children from minority and socio-economically disadvantaged backgrounds are disproportionately exposed to unhealthy food advertising.

Regulations to restrict unhealthy food advertising to children should be implemented to improve children’s diets and reduce inequities in dietary intake.
