31% of children had a non-optimal (14%) or questionable (17%) Behavior Rating Scale score for Emotional Regulation, and 27% for Orientation/Engagement (O/E). These children were more likely to have MDI and PDI scores <70 and be unable to walk. Antecedents of low scores include multi-fetal pregnancy, indicators of socioeconomic disadvantage, and male sex. Over 25% of children born extremely premature exhibit socio-emotional delays during developmental assessment at age 2 years.
