Abstract

The percentage of United States cesarean births increased from 20.7% in 1996 to 31.1% in 2006. Cesarean rates increased for women of all ages, race/ethnic groups, and gestational ages and in all states. Both primary and repeat cesareans have increased. Increases in primary cesareans in cases of "no indicated risk" have been more rapid than in the overall population and seem the result of changes in obstetric practice rather than changes in the medical risk profile or increases in "maternal request." Several studies note an increased risk for neonatal and maternal mortality for medically elective cesareans compared with vaginal births.

摘要

美国剖宫产率从1996年的20.7%上升至2006年的31.1%。所有年龄、种族/族裔群体、孕周的女性以及所有州的剖宫产率均有所上升。初产妇和经产妇的剖宫产率都增加了。“无明确风险”情况下初产妇剖宫产率的增长速度超过了总体人群，这似乎是产科实践变化的结果，而非医疗风险状况的改变或“产妇要求”的增加。几项研究指出，与阴道分娩相比，择期剖宫产的新生儿和产妇死亡风险增加。
