Advanced maternal age is a risk factor for Caesarean section following induction of labour. A recent publication by Dunne and Kumar (ANZJOG 17th March 2017), found that after induction of labour in women with a maternal age of over 35, the risk of delivery by Caesarean section was twice that of the general population. Despite this the majority of women over 35 delivered vaginally. It is known that women over 35 were more likely to have a medical indication as the reason for the induction e.g. hypertension or diabetes. The reason for the increased Caesarean section rate may be that as the muscle in the uterus ages, it is less effective in oxygenating the foetus. Also, with an increased risk of medical problems as mothers age there is a decreased tolerance for labour. These are interesting findings and warrant further observation.
