Ethics approval and consent to participate
: The study was approved by and carried out under the guidelines of the medical ethics committee at Shiraz University of Medical Sciences, Shiraz, Iran. Written informed consents and filled questionnaires on age and education from the neonates’ parents and participating mothers (mean age 27.7; range: 18–45 years) were obtained for sample collection and subsequent analysis. In doing so, we used written forms filled by the participants themselves (those who were educated) or by the visitors, who accompanied the illiterate ones and on behalf of them. The items in both consent form and questionnaires were initially read for the illiterate participants and filled by the accompanying visitors based on their answers.
