Objective To evaluate the impact of food advertising on childhood obesity by reviewing relevant literatures, and to provide evidence support for childhood obesity prevention and control strategies in China. Methods A systematic review method was used to search relevant literatures published to November 30,2020 from 8 databases including CNKI, VIP, Wanfang Data, PubMed, Medline, SpringerLink, Web of Science, Science Direct. The high-quality systematic reviews published since 2016 were included directly, and those published before 2016 were rereviewed after combined with other literatures. Results A total of 13 articles were included for evaluation, including systematic reviews, cohort studies, randomized controlled trials and cross-sectional studies. Children’s exposure to food advertisements could increase energy intake. Television food advertising could influence children’s food choices and increase the consumption of unhealthy foods such as sweets and sugary drinks. Children’s exposure to unhealthy food advertisements could increase the risk of obesity. Conclusion Regulating the food advertisement can help reduce the risk of childhood obesity.
