The benefits of breastfeeding and the negative effects of artificial feeding in underprivileged environments were clearly brought to the public attention in the 1970s, backed by increasingly strong scientific support. As a result the International Code of Marketing of Breast-milk Substitutes and subsequent World Health Assembly Resolutions were created in the 1980s to avoid the marketing of infant foods, teats and bottles in ways that could interfere with breastfeeding. In the early 1990s, UNICEF started the "Baby-friendly Hospital Initiative" (BFHI), which decreased many of the practices in the health care system that had a negative impact on breastfeeding. Together with many of the other child health programmes during these decades these interventions contributed to a reduction in child morbidity and mortality.
