Among the several risk factors are East Asian race and delayed cord clamping. Birth centers manage low\u2010risk term deliveries using physiological management, which may include delayed cord clamping.

Data were collected from March 2006 to October 2014 from healthy mothers and neonates at a birth center in a metropolitan area of Japan.
