The Caesarean section rate has been increasing during the last 50 years.1 The rate was 5% in the 1940s and 1950s and remained unchanged for 10 to 15 years. In the late 1970s, the rate rose to 15% and remained unchanged for the next 10 years. In the last decade there has been a dramatic increase in the Caesarean section rate worldwide, which now exceeds 30% in some regions.1 The latest Statistics Canada Caesarean section rate published in 2009 is 26.8%, with provincial rates ranging from 20.2% in Manitoba to 31.5% in Newfoundland and Labrador.2 Although several guidelines, including those issued by the World Health Organization3 and the United States Healthy People 2000 initiative,4 suggest that the optimal Caesarean section rate is 15%, there seems to be little effect on the current Caesarean section rate.
