Recent study investigated the relationship between second-trimester anthropometric obesity indicators and cesarean section (CS) in Chinese pregnant women, aiming to identify effective predictors to reduce unnecessary CS rates. Maternal obesity during the second trimester has been linked to an elevated CS risk, emphasizing the need for reliable obesity indicators for prenatal risk assessment. The study included a large sample of Chinese pregnant women, and statistical analyses revealed significant correlations between anthropometric indicators and CS risk after adjusting for covariates. Recommendations for CS Risk AssessmentIntegrated approaches combining BMI and WC were recommended for effective CS risk assessment, with BRI being a superior indicator despite its complexity.
