Asphyxia was defined as an Apgar score &amp;lt;7 at 5 min post-delivery with umbilical cord arterial blood pH &amp;lt; 7.2 in the infant born after 34weeks. We compared the perinatal maternal characteristics of the newborns who developed asphyxia (NA group, <jats:italic>n<\/jats:italic> = 1,152) and those who did not (no NA group, <jats:italic>n<\/jats:italic> = 86,393).
