title: Trends in caesarean section in Western Australia, 1980-1987.
abstract: During the 1980s the incidence of both emergency and elective caesarean section in Western Australia increased, accompanied by a decrease in that of all other delivery methods. The proportion of emergency caesarean sections increased from 5.9%. of all deliveries in 1980 to 8.2% in 1987 and that of elective sections from 5.3% to 8.7%. For each year studied less than 50% of primiparous women delivering singletons had a normal vaginal delivery. Emergency caesarean sections were more common in primiparas and at the teaching hospital and elective sections in multiparas and at the metropolitan private hospitals. The proportion of primiparas having either emergency or elective caesarean sections rose with maternal age, but for multiparas the proportion having elective sections rose, but there were few differences in emergency sections with increasing age. Repeat caesarean sections, which made up 28.8% of the total in 1987, have contributed increasingly to the rising proportion of caesarean section deliveries. Unless the number of emergency sections in primiparous women falls and the challenge of vaginal birth after caesarean section is met, it is likely that the caesarean section rate in Western Australia will continue to increase over the next decade.
