ABSTRACT
OBJECTIVE:
To determine whether increasing maternal age increases the risk of operative delivery and to investigate whether such a trend is due to fetal or maternal factors. DESIGNANALYSIS:
of prospectively collected data on a maternity unit database.SETTING:
A postgraduate teaching hospital. POPULATION 6410 nulliparous women with singleton cephalic pregnancies delivering at term (3742 weeks of gestation) between 1 January 92 and 31 December 95. MAIN OUTCOMEMEASURES:
Mode of delivery, rates of prelabour caesarean section, induction of labour and epidural usage.RESULTS:
There was a positive, highly significant association between increasing maternal age and obstetric intervention. Prelabour (P < 0.001) and emergency (P < 0.001) caesarean section, instrumental vaginal delivery (spontaneous labour P < 0001; induced labour P = 0.001), induction of labour (P < 0.001) and epidural usage in spontaneous labour (P = 0.005) all increased with increasing age. In the second stage of labour fetal distress and failure to advance, requiring instrumental delivery, were both more likely with increasing maternal age (in both P < 0.001). Epidural usage in induced labour and the incidence of small for gestational age newborns did not increase with increasing maternal age (P = 0.68 and P = 0.50, respectively).CONCLUSIONS:
This study demonstrates that increasing maternal age is associated with an incremental increase in obstetric intervention. Previous studies have demonstrated a significant effect in women older than 35 years of age, but these data show changes on a continuum from teenage years. This finding may reflect a progressive, age-related deterioration in myometrial function.
