    ABSTRACT: This multi-center correlational prospective study examined early neonatal predictors of neurodevelopment in 59 premature infants (mean birth weight=1713.8+/-1242.5 g; mean gestational age=31.2+/-3.6 weeks) suspected to have sustained brain injury at birth. The mental and motor development of the infants selected from five university-affiliated hospitals was assessed at baseline (59 infants), 12 (55 infants), and 18 months (46 infants) using Bayley II scales. Factors correlating with Bayley II scores at 12 and 18 months included head circumference, results of neurological and magnetic resonance imaging (MRI) examination at baseline, environmental factors such as mother-infant interactions and levels of parental stress, and infant medical factors such as Apgar scores at 5 min and length of hospital stay. Multiple regression analyses distinguished the most significant predictors of mental and motor development. The best predictors of mental and motor development at 18 months were head circumference, neurological examinations, and MRI results. These findings suggest that in infants suspected of brain injury at birth, neurological assessments and head circumference measurements are just as predictive of developmental outcome at 18 months as MRI, and this is especially relevant in developing countries or other locations where MRI is not possible. The presence of this information may offer the potential of early tailored interventions to improve the mental and motor development of children in developing countries or other facilities where MRI is unavailable.

    ABSTRACT: We investigated the influence of biological immaturity and attachment security on linguistic development and tested whether maternal language mediated the impact of security on the child’s linguistic abilities. Forty mother–child dyads were followed longitudinally, with the child’s attachment security assessed at 24 months of age through trained observers’ Attachment Q-Sorts, and linguistic abilities assessed at 24 and 30 months through observational measures and maternal reports. Both factors were found to contribute, though not independently, to the prediction of the child’s linguistic abilities, and the mediation model was confirmed.

    ABSTRACT: A cohort of 28 VLBW (less than or equal to 1500 g) infants was assessed at 1 and 3 years of age for hearing, language development and neurological status. Language delays were detected in 11 (39%) infants at 1 year, and in four (15%) at follow up at 3 years of age (P less than 0.05). Language quotients were significantly associated with perinatal variables at 1 but not at 3 years of age. Infants with neurological abnormalities had significantly lower language quotients at the 3-year follow up. No child with a normal language profile at 1 year exhibited a delay at 3 years of age.
