Over recent decades, the prevalence of obesity has risen dramatically worldwide.Recent reports indicate that at least half the women in many countries are overweight or obese, including up to a third of women of reproductive age.As result of the increase in obesity in women of reproductive age, the prevalence of obesity in pregnancy has also risen dramatically.Increased complications of labour and delivery are linked to obesity in pregnancy.Maternal obesity has been found to slow cervical dilatation and increase the risk of prolonged labour.Obese pregnant women have higher rates of medical interventions around labour and birth, including higher rates of induction for prolonged pregnancy and higher rates of Caesarean section as a result of failure to progress in labour.This has implications for service delivery as higher rates of operative deliveries require greater utilisation of theatre and anaesthetic services,longer bed stays, more intensive nursing postpartum and higher rates of postpartum and longer term complications, including an increased need for Caesarean delivery in future pregnancies and potentially life threatening outcomes such as placenta praevia and accreta.One possible explanation for the dysfunctional labour mechanism in obese women is that changes occur in the composition of the membranes of uterine muscle ceils in such women.These changes may influence the electrophysiological and contractile properties of uterine muscle.A greater understanding of such changes will facilitate improved obstetric management of this increasingly important group of obstetric patients.
