Abstract

Purpose: To explore the relationships between second-trimester anthropometric obesity indicators and cesarean section (CS).

Methods: A retrospective study was conducted at West China Second University Hospital, utilizing electronic health records from 15,304 pregnant women who received routine prenatal care and delivered between January 2021 and June 2022. Second-trimester anthropometric indicators, including body roundness index (BRI), body mass index (BMI), body fat percentage (BFP), and waist circumference (WC), were measured using bioelectrical impedance analysis (BIA). Logistic regression models were employed to assess the associations between these indicators and CS risk, with additional subgroup analyses based on maternal age and fetal sex.

Results: The mean maternal age was 30.13 years. After adjusting for covariates, BRI (OR 1.22, 95%CI 1.15-1.30), BMI (OR 1.07, 95%CI 1.05-1.08), BFP (OR 1.03, 95%CI 1.02-1.04), and WC (OR 1.02, 95%CI 1.01-1.03) were all significantly associated with CS. Stratified analyses based on maternal age and fetal sex further confirmed these independent associations.

Conclusion: Second-trimester BRI, BMI, BFP, and WC were all significantly associated with CS risk, with BRI potentially demonstrating the strongest independent correlation. An integrated approach incorporating BMI and WC is recommended for CS risk, particularly in time-sensitive or resource-limited settings. The effect of anthropometric changes during pregnancy on CS may be explored in the future.

剖宫产妊娠中期人体测量指标：体圆度指数、体重指数、体脂率和腰围之间的一致性。

目的：探讨妊娠中期人体测量肥胖指标与剖宫产（CS）的关系。方法：利用2021年1月至2022年6月期间接受常规产前护理的15304名孕妇的电子健康记录，在华西第二大学医院进行回顾性研究。采用生物电阻抗分析法（BIA）测量孕中期人体测量指标，包括体圆度指数（BRI）、体重指数（BMI）、体脂率（BFP）和腰围（WC）。采用Logistic回归模型来评估这些指标与CS风险之间的关系，并根据母亲年龄和胎儿性别进行额外的亚组分析。结果：产妇平均年龄30.13岁。调整协变量后，BRI （OR 1.22, 95%CI 1.15-1.30）、BMI （OR 1.07, 95%CI 1.05-1.08）、BFP （OR 1.03, 95%CI 1.02-1.04）和WC （OR 1.02, 95%CI 1.01-1.03）均与CS显著相关。基于母亲年龄和胎儿性别的分层分析进一步证实了这些独立的关联。结论：妊娠中期BRI、BMI、BFP和WC均与CS风险显著相关，其中BRI可能表现出最强的独立相关性。对于CS风险，特别是在时间敏感或资源有限的情况下，建议采用结合BMI和WC的综合方法。妊娠期人体测量变化对CS的影响有待进一步探讨。
