Growth discordancy in appropriate for gestational age, term twins.
We compared 14 term (37 weeks or more), discordant (15% or more birth weight difference), but not growth-retarded (2500 g or larger) twin pairs with 28 randomly selected term and appropriate for gestational age twin pairs without discordancy. The comparison of the two subgroups showed no significant difference in maternal age, parity, gestational age, incidence of maternal hypertension, or perinatal outcome. It is suggested that discordancy is not a risk factor when the twin pair has reached term and the lighter twin weighs at least 2500 g.
