Abstract
Data from a national sample of 6,688 infants from birth to one year old are analysed. The children were studied by the “status quo” method, using univariate logistic regression, together with several specially created indices, which constitute a methodological contribution. Very low/levels of exclusive breast-feeding were found, particularly at three months of age (prevalence of 25% for the whole country, when it should still be being practiced for all children. In a considerable number of cases it had been begun but then abandoned: flour out of ten babies who were breast-fed at birth were consuming other milk 90 days/later. The geographic pattern of breast-feeding across the country reveals a historical/truck of cultural influence that has weakened natural/habits through the incorporation of Western behavioural values.
