Abstract		Study objective: the effect of the risk factors related to the mother, pregnancy, labour, the infant and working hours of the maternity hospital on the incidence of asphyxia in singleton term breech infants, the analysis not including infants with lethal malformations and antepartum deaths. Design: retrospective cohort study based on computerized data system. The first part of investigation covers the period from 1 January 1988 to 31 December 1990 and the second part the period from 1 January 1987 to 31 December 1990. Setting: 14 maternity hospitals in Slovenia. Study populations: Mortality in 2,229 singleton term breech infants was compared to mortality in 67,139 singleton term vertex infants. Perinatal outcome of labour in 2,196 cases of singleton term breech infants, infants with lethal malformations and antepartum deaths excluded, was compared to 66,587 vertex infants. The effect of the risk factors on the incidence of asphyxia was investigated in a group of 2,952 singleton term breech infants, infants with lethal malformations and antepartum deaths excluded from the analysis. Results: Lethal malformations were in infants with breech delivery found five times more often than in infants with vertex delivery. Stillbirths occurred in 10.4%. of newborns with breech delivery, perinatal mortality in 17.1%., and neonatal mortality in 8.6%. (9.9%., 13.0%. and 4.1%. respectively after correction for lethal malformations). Mortality in newborns with breech delivery was five times greater than in newborns with vertex delivery.
