Population-based data from the Cardiff Births Survey has been used to examine the trends in obstetric intervention with increasing maternal age. As maternal age increases, spontaneous vaginal delivery rates fall, instrumental delivery rates, elective and emergency caesarean section, induction of labour and epidural rates rise. Induction of labour and epidural in labour are both associated with decreased spontaneous vaginal delivery rates and an increase in instrumental delivery rates and emergency caesarean section.
来自加的夫出生调查的基于人群的数据已被用于研究随着产妇年龄增加产科干预的趋势。随着产妇年龄的增长，自然阴道分娩率下降，器械助产率、择期和急诊剖宫产率、引产率和硬膜外麻醉率上升。引产和分娩时硬膜外麻醉均与自然阴道分娩率降低以及器械助产率和急诊剖宫产率增加有关。
