in the vital statistics the cesarean section is a cause that makes reference to births and deaths.
to analyze the frequency of the cesarean section, the changes brought about in the rates of maternal, perinatal mortality and of natality, and their relation with reliable contraceptive methods.
retrospective study realized with the dices of patients of the Coordination of Reproductive Health of the Mexican Institute of the Social Insurance (IMSS) of the state of Aguascalientes (Mexico). The births were registered majors of 20 weeks of gestation, the maternal and perinatal deaths from 1990 to 2007 in the hospitals of the IMSS in Aguascalientes. The rate of cesarean calculated by means of the registry of the number of the same realized per year and they were divided between the total of vaginal and abdominal births, and the result multiplied percent.
201,563 obstetrical events were registered, of which 145,106 corresponded to vaginal childbirths and 56,457 abdominal ones. With these data a global rate of cesarean section of 28% was obtained, with 201,182 new born alive ones and 2,618 perinatal ones. The acceptance of the tubary bilateral occlusion maintained a constant increase during the period of study, like the intrauterine device. The acceptance from the bilateral occlusion was completely different tubary during the cesarean one, in comparison with the childbirth.
the long term results show positive influence in the reduction of the rate of natality.
在人口动态统计中，剖宫产是涉及出生和死亡的一个原因。
分析剖宫产的频率、孕产妇、围产期死亡率和出生率的变化，以及它们与可靠避孕方法的关系。
对墨西哥阿瓜斯卡连特斯州社会保险机构（IMSS）生殖健康协调处的患者记录进行回顾性研究。记录妊娠20周以上的分娩情况，以及1990年至2007年阿瓜斯卡连特斯州IMSS医院的孕产妇和围产期死亡情况。剖宫产率通过每年记录的剖宫产数量除以阴道分娩和剖宫产总数，结果乘以百分比来计算。
记录了201,563例产科事件，其中145,106例为阴道分娩，56,457例为剖宫产。据此得出剖宫产总率为28%，有201,182例活产新生儿和2,618例围产儿。在研究期间，双侧输卵管结扎术的接受率持续上升，宫内节育器的情况也一样。与分娩相比，剖宫产时双侧输卵管结扎术的接受情况完全不同。
长期结果显示对降低出生率有积极影响。
