Recent Trends in Cesarean Delivery in the United States

In 2007, nearly one-third (32%) of all births were cesarean deliveries (1). Although there are often clear clinical indications for a cesarean delivery, the short- and long-term benefits and risks for both mother and infant have been the subject of intense debate for over 25 years (2). Cesarean delivery involves major abdominal surgery, and is associated with higher rates of surgical complications and maternal rehospitalization, as well as with complications requiring neonatal intensive care unit admission (3–5). In addition to health and safety risks for mothers and newborns, hospital charges for a cesarean delivery are almost double those for a vaginal delivery, imposing significant costs (6).
This report shows trends in cesarean delivery since 1991, focusing on the period from 1996 to 2007 when cesarean rates began to rise following a decline in the early 1990s. Data for 2007 are preliminary and 2006 data are presented when preliminary 2007 data are not available (1,7).
