Iowa's C-section rates on the rise

Line chart showing the annual share of babies delivered by cesarean section in Iowa and the U.S. from 2016 to 2023. In 2016, 31.9% of U.S. babies were delivered by c-section, compared to 32.4% in 2023. In Iowa, the share changed from 30.1% to 30.3% in the time period.
Data: CDC; Chart: Axios Visuals

The rate of cesarean births in Iowa has gone up since 2016 to a little over 30%, according to new data from the CDC.

  • Nationally, the C-section delivery rate in 2023 came to 32.4%.

Why it matters: That's well above the 10-15% rate that the WHO considers "ideal."

State of play: Repeat C-sections account for many of the procedures nationally, even though most individuals can have a successful vaginal birth after a cesarean section (VBAC).

Yes, but: In Iowa, it's especially difficult to find a provider who will offer that option, says Rachel Bruns, the International Cesarean Awareness Network's local chapter leader.

  • Last year, MercyOne ended the only hospital-based midwifery program in Des Moines that offered VBAC.
  • That is directly affecting C-section rates, Bruns tells Axios as well as worse patient outcomes, such as placenta accreta, a life-threatening condition.

Between the lines: Health care system reimbursements for C-sections are generally higher than for vaginal births. "Financial incentives almost always play some role," says Emily Oster, economist and author of "The Unexpected,"

  • Some Des Moines hospitals outright ban VBAC services, while others have no policies and leave it up to the doctors to decide, Bruns says.
  • Doctors may recommend C-sections to avoid increased liability, Bruns says.

What they're saying: The country's higher C-section rate can also be attributed to care that prioritizes practitioners rather than midwives, who can provide more specific attention to patients, Bruns says.

  • Iowa's Medicaid rate reimburses certified nurse midwives at only 85% of the rate for physicians, which does not incentivize hospitals to offer midwifery care.

Reality check: Vaginal deliveries also come with their own risks.

  • And there are many situations — like in cases of breech birth, the presence of certain placenta problems or severe preeclampsia — where a C-section should be performed, says Jane van Dis, OB-GYN and assistant professor at the University of Rochester.
