[Maternal and neonatal factors determining bilirubinemia during the 1st four days of life]. / Fattori materni e neonatali nel determinismo della bilirubinemia nei primi quattro giorni di vita.

The influence of various maternal and neonatal factors on blood bilirubin is examined. An increase in neonatal values may be due to the relatively advanced age of the mother, whereas neonatal age, sex and weight, increase in maternal weight during pregnancy, and maternal body surface area would appear to be without influence.
