Full-term neonate twins from weight-discordant pairs were compared with nondiscordant
pairs on perinatal variables, minor physical anomalies, developmental status, and
temperament/interactive measures. For perinatal variables, twins from the top quartile of
discordance were found to be at higher risk than other twins. Both the total group of
discordant twins and twins with the most extreme discordance had higher weighted minor
physical anomaly scores, more minor physical anomalies, and lower developmental status …
