[Determination of newborn feeding in maternity hospital care. Part I: Factors associated with breast feeding initiation].

The data on 11,750 newborns collected in 427 hospitals during the survey of maternity words practices in 1995 were used to analyse the factors related to breastfeeding initiation while in hospital. The statistical analyses were done using percentage of newborn breastfed as well as odds ratio (OR) and population attributable risk in percent (PAR%) of artificial feeding. The identified factors of artificial feeding were: newborn birth weight < 2500 g (OR = 28.2; PAR = 52%), complications in neonatal period (OR = 10.3; PAR = 64%), caesarean section (OR = 4.3; PAR = 32.2%), mother and newborn separation longer than 1h/24h (OR = 13%; PAR = 87.2%), lack of skin-to-skin contact after birth (OR = 8.5; PAR = 60.9%).
