Obesity should not guide shoulder dystocia risk assessment independently; leaves open macrosomia as primary mediator in larger prospective cohorts.
Is maternal obesity an independent predictor of shoulder dystocia in singleton cephalic vaginal deliveries?

Robinson et al. (2003) studied this question.
