Improvement of surgical techniques, innovation, and technological development have increased the frequency of cesarean section.
To identify the sociodemographics, obstetrical, attention and medical practice factors of risk most frequently associated to cesarean section.
From January to June 2007, we carried out a study of cases and controls with 222 cases of cesarean section and 358 controls of vaginal childbirth in Hospital General no. 6 of Ciudad Juárez. We compared frequency of sociodemographics, obstetrical, attention, and medical practice variables, by means of chi2 and Fisher exact tests; association among these variables and cesarean section was considered with odds ratio. In all cases chosen confidence interval was 95%.
Risk factors associated with cesarean section were: maternal age over 28 years, previous cesarean section, complicated pregnancy, fetal suffering, cephalopelvic disproportion, deficient prenatal care; fetal podalic version, oxytocin administration, abnormal amniotic fluid, double- or triple-circle umbilical cord; patient attended by a gynecologist with more than 16 years of experience and by a resident; and medical care in evening shift. There was no association with age, menarche, beginning of sexual relationships, body mass index, smoking, or addictions.

手术技术的改进、创新和技术发展增加了剖宫产的频率。
确定与剖宫产最常相关的社会人口统计学、产科、护理及医疗实践风险因素。
2007年1月至6月，我们在华雷斯市第6综合医院对222例剖宫产病例和358例阴道分娩对照进行了病例对照研究。我们通过卡方检验和费舍尔精确检验比较了社会人口统计学、产科、护理及医疗实践变量的频率；这些变量与剖宫产之间的关联通过比值比来考量。在所有选定的病例中，置信区间为95%。
与剖宫产相关的风险因素有：产妇年龄超过28岁、既往剖宫产史、妊娠合并症、胎儿窘迫、头盆不称、产前检查不足；胎位异常、使用缩宫素、羊水异常、脐带双绕或三绕；由经验超过16年的妇科医生和住院医师诊治的患者；以及夜班医疗护理。与年龄、初潮、开始性行为、体重指数、吸烟或成瘾无关。
