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.Data are available upon reasonable request.
