title: [Concentration of bilirubin in the neonatal stage in relation to the use of contraceptives].
abstract: The present study was carried out with the purpose of determining whether the use of contraceptives by the mothers constitutes an important factor in the elevation of unconjugated bilirubin in breast fed newborns. One hundred mothers of full term healthy newborns with adequate weights for their gestational ages were asked on this point. Twenty-four hours after birth, breast feeding was initiated and at 72 hours, the level of bilirubins was investigated. The results showed a significant difference in favor of the total bilirubin concentration and its indirect fraction in the 45 infants from mothers who had taken contraceptives.
