Caesarean Births Doubled Around the World Amid Signs of Both Overuse and Underuse

Allison Inserro
The number of infants born through caesarean section (C-section) almost doubled between 2000 and 2015—from 12% to 21% of all births—according to The Lancet. The surgery is still unavailable for many women in low-income countries and regions, yet is overused in many middle- and high-income settings, said the journal, which published a series of papers on the topic Thursday.
C-section continues to be overused in North America, Western Europe and Latin America and the Caribbean, where rates increased by around 2% per year between 2000 to 2015. C-section use increased from 24.3% to 32% in North America, from 19.6% to 26.9% in Western Europe, and from 32.3% to 44.3% in Latin America and the Caribbean. 

The global increases in C-section use are attributed both to more births taking place in health institutions (about two-thirds of the increase) and to greater frequency of intervention through C-section (about one-third of the increase). C-sections are underused across sub-Saharan Africa (around 2% per year), where C-section use has remained low. 

C-section harms
There are no benefits of C-section in cases without a medical indication, and there are short and long-term risks associated with C-sections for both mothers and children.2 Harm and even death can occur, especially when there are not sufficient facilities, skills, and health care available, the researchers noted.

For mothers, maternal death and disability is higher after C-section than vaginal birth. C-sections have a more complicated recovery, and lead to scarring of the womb, which is associated with bleeding, abnormal development of the placenta, ectopic pregnancy, stillbirth, and preterm birth in subsequent pregnancies. 

For infants, there is emerging evidence that C-section births can lead to different hormonal, physical, bacterial, and medical exposures during birth, which can subtly alter their health. While the long-term risks of this are not well-researched, the short-term effects include changes in immune development, which can increase the risk of allergies and asthma and alter the microbiome. 

Talking about C-section overuse with patients
According to the series, some women request C-sections because of past negative experiences of vaginal birth, fear of labor pain or of the effects of labor such as pelvic floor damage or urinary incontinence.3 To address this, the authors recommend further research to study relaxation training, childbirth training workshops, educational outreach, and meeting with healthcare professionals. 

For healthcare professionals, improved education, guidelines and communication, and second-opinion policies may also be helpful to address influences such as women’s requests, convenience, financial incentives, and fear of litigation. In particular, in some regions C-sections are seen as protective, and physicians are less likely to be sued if complications occur, than during vaginal delivery. 

The authors warn that young physicians are becoming experts in C-section, while losing confidence in their skills to assist in vaginal birth.
