(HealthDay News) — The rate of cesarean sections in a subset of U.S. states increased between 2006 and 2009 and then declined through 2012, according to a report published in the Jan. 23 issue of the U.S. Centers for Disease Control and Prevention’s National Vital Statistics Reports.
In an effort to assess trends in primary cesarean delivery rates, Michelle J.K. Osterman, M.H.S., and colleagues from the National Vital Statistics System in Hyattsville, Md., analyzed all singleton births from 2006 to 2012 from states that implemented the 2003 U.S. Standard Certificate of Live Birth.
For the 2006 reporting area (19 states), the researchers found that the cesarean rate increased from 21.9% in 2006 to 22.4% in 2009 and decreased to 21.9% in 2012. For the 2009 reporting area (28 states and New York City), the rate decreased from 22.1%t in 2009 to 21.5% in 2012. Cesarean rates at 38 weeks of gestation declined for 18 of the 29 areas from 2009 to 2012 but remained unchanged at other gestational ages. In 2012, cesarean rates ranged from 12.5% in Utah to 26.9% in Florida and Louisiana.
“Overall, primary cesarean delivery rates for the 19 states that implemented the revised birth certificate by 2006 increased from 2006 to 2009 and then declined from 2009 to 2012,” Osterman and colleagues write.
