Digital Marketing of Breast-Milk Substitutes: a Systematic Scoping Review

Globally, too few children are breastfed as recommended. Commercial promotion of breast-milk substitutes (BMS) is one factor undermining breastfeeding globally. Although the International Code of Marketing of BMS prohibits all forms of marketing, promotion has been observed in digital environments. We aimed to understand the scope and impact of digital marketing for the promotion of BMS.

BMS are promoted strategically and in an integrated fashion across multiple digital channels (social media, manufacturer websites, online retailers, blogs, mobile apps and digital streaming services). Traditional marketing strategies like gifts, discounts and coupons are also disseminated digitally. Data mining, real-time direct-to-consumer advertising and partnering with peer-group social media influencers are additional avenues. Exposure to digital marketing is common. Research on the impact of digital marketing is scarce, but its negative impact on breastfeeding intention and initiation has been documented. Case reports from marketing industry press corroborate academic evidence by highlighting the benefits of digital marketing to BMS companies in recruiting new users and increasing sales. To protect and promote breastfeeding, coordinated global action and strengthened national measures will be needed to implement, monitor and enforce the International Code in a digital context. Further action could include voluntary restrictions on BMS marketing by social media platforms and greater use of government-led data and health privacy regulation.
