Sociodemographic and Health-Related Risk Factors Associated With Planned and Emergency Cesarean Births in Mexico.

Background: Cesarean delivery is a contributing factor to many delivery care and postpartum maternal morbidities, especially when a cesarean delivery is unnecessary. Mexico has one of the highest cesarean birth rates in Latin America, and as such, our objective was to identify the sociodemographic, reproductive, maternal care, and health-related characteristics associated with the prevalence of planned and emergency cesarean births in Mexico.

Methods: Using nationally representative data from a Mexican probabilistic survey (ENSANUT 2021), we examined and developed a cross-sectional analysis of women aged 12 to 19 with a live-birth and women 20 to 49 years who had their last live-birth within five years before the survey (n = 1330). We used multinomial logistic regression analysis to examine predictors associated with planned and emergency cesarean births.

Results: The live-births within our sample included 50.7% vaginal, 27.5% emergency cesarean births, and 21.8% planned cesarean births. Younger age groups at delivery, speaking an indigenous language, and receiving delivery care at open public services are negatively associated with having any cesarean birth. Receiving delivery care at private institutions and having hypertension during pregnancy increases the odds of having both planned and emergency cesarean births. Emergency cesarean births are positively associated with tertiary education and negatively correlated with the parity of three or more children, while planned cesarean births are more likely for women with a parity of two.

Discussion: Efforts to reduce unnecessary cesarean births should include evidence-based medicine recommendations, actions to avoid the first cesarean birth, and providing pregnant women with counseling to support informed decisions.
