RESUMEN

Current international infant and young child (IYC) feeding recommendations consider nutrition and health but not environmental impacts. Only a handful of countries have dietary guidelines that provide quantitative recommendations for food groups of environmental concern. OBJECTIVE: To perform a narrative review of the environmental impacts of commercial milk formula vs. breastfeeding, and to analyze the degree to which current country-specific IYC feeding recommendations are aligned with sustainable dietary targets. METHODS: A mixed methods review was conducted, including : a) a narrative review of the environmental impact of commercial milk formula compared with breastfeeding, and b) a comparison of recommended intake of meats and dairy for children IYC based on country-specific dietary guidelines vs. the Eat-Lancet Commission dietary targets (ELCT) for children 24 months or older and adults and if the ELCT should be adjusted for the energy needs of IYC. RESULTS: Formula feeding has a greater environmental impact (∼48% higher carbon footprint) compared to exclusive breastfeeding. Available country-specific dietary guidelines for meat and dairy products in children IYC are, in general, at or below the upper limits of the ELCT recommended ranges for older children and adults but are in most cases above the upper limit when adjusting for the energy needs of IYC. CONCLUSIONS: Exclusive breastfeeding should be protected and promoted not only as the healthier but also as the most sustainable alternative. Available complementary dietary feeding recommendations of non-processed meat and dairy fall below current ELCT for older children and adults. Given that IYC requiere a more nutrient-dense diet than older children and adults, and considering the small quantities they consume, we recommend using the unadjusted ELCT as reference for IYC feeding while specific international consumption recommendations are developed for this age group.

RESUMEN

BACKGROUND: Parents are exposed to breastmilk substitutes and baby foods marketing on the internet and social media, which hinders adequate breastfeeding and complementary feeding. This study identifies digital marketing strategies for breastmilk substitutes, specifically commercial milk formula and baby foods used by the industry to influence infant and young children's feeding practices in Mexico and proposes regulatory recommendations that can be useful for similar countries. METHODS: Qualitative study based on the CLICK monitoring framework developed by the World Health Organization, adapted for digital marketing of commercial milk formula and baby foods. Semi-structured interviews (n = 53) with key actors were conducted between November 2020 and March 2021, and used grounded theory for the analysis and interpretation with the MAXQDA 20 software. RESULTS: Commercial milk formula and baby food companies use digital media to contact and persuade parents to use their products by sending electronic newsletters with advertising. Companies hire influencers to market their products because there is no regulation prohibiting the advertisement of breastmilk substitutes on social media, and promote formula among health professionals inviting them to participate in sponsored webinars on infant nutrition, ignoring conflict of interest and the International Code of Marketing of Breastmilk Substitutes. Parents trust formula and baby food advertisements, which use emotional messages and health and nutrition claims to encourage their consumption. Health professionals consider that claims contribute to the indiscriminate use of formula, and some actors propose the use of plain packaging for these products. CONCLUSIONS: Breastmilk substitutes companies promote their products in digital media using unethical strategies that fail to comply with the International Code of Marketing of Breastmilk Substitutes. They generate strong conflicts of interest with health professionals, taking advantage of legal framework gaps and the lack of monitoring and effective sanctions for non-compliers. Updating the legal framework and monitoring compliance, including digital media, is urgently needed to protect children's right to breastfeeding, healthy nutrition and life, and the rights of women to health and informed decision-making.

RESUMEN

BACKGROUND: There is little evidence of the association between digital marketing of formula and baby food and infant and young child feeding (IYCF) practices. OBJECTIVE: Assess parents' exposure to digital marketing of formula and baby food for children <2 years and its association with the purchase and IYCF practices in Mexico. METHODS: Parents ≥18 years recruited from a market research panel completed an online survey (n=1074) and capture-on-screen (n=95) between December 2020 and January 2021. Logistic regressions were used to estimate the association between exposure to digital marketing of formula and baby foods with its purchase, motivation, consumption and IYCF practices. RESULTS: Digital marketing of formula and baby food was self-reported by 93.9% of parents in the online survey and observed by 93.7% in the capture-on-screen. Recorded ads did not comply with the International Code of Marketing of Breast-milk Substitutes. Parents who self-reported seeing a higher versus lower number of ads were less likely to exclusive breast feed (OR=0.38; 95% CI: 0.19 to 0.78), and more likely to give mixed feeding (OR=2.59; 95% CI: 1.28 to 5.21), formula (OR=1.84; 95% CI: 1.34 to 2.53), processed foods (OR=2.31; 95% CI: 1.59 to 3.32) and sugary drinks (OR=1.66; 95% CI: 1.09 to 2.54). Higher exposure to ads was associated with a higher chance of purchasing products motivated by nutritional (OR=2.1; 95% CI: 1.32 to 3.28) and organic claims (OR=2.1; 95% CI: 1.21 to 3.72). CONCLUSIONS: Digital marketing of formula and baby food may negatively influence IYCF and should be regulated to ensure children's nutrition and health.
