ABSTRACT

BACKGROUND: Relatively little is known about the early social development of children born very preterm despite clear suggestions of later interpersonal difficulties. AIMS: To compare the social competence of very preterm (VPT) and full term (FT) born children at age 4 and identify infant, social and family factors associated with later risk. STUDY DESIGN: Prospective longitudinal study. SUBJECTS: A regionally representative cohort of 103 VPT (≤ 32 weeks gestation) children and a comparison group of 105 FT children (36-41 weeks gestation) born between 1998 and 2000. OUTCOME MEASURES: At corrected age 4 years, a range of parent report, observational and laboratory measures assessed children's emotional and behavioral adjustment, emotional regulation, social interactive behavior and theory of mind understanding. Extensive perinatal, social background and family functioning data were also available from birth to age 4. RESULTS: Compared to their FT peers, VPT born children had poorer emotional and behavioral adjustment, were less effective in regulating their emotions, had lower levels of positive peer play and had less synchronous interactions with their parents. Within the VPT group, predictors of poor social competence included family socioeconomic disadvantage, extreme prematurity, severity of cerebral white matter abnormalities and early childhood exposure to high levels of maternal anxiety and negative parenting. CONCLUSIONS: VPT pre-schoolers are characterized by a range of subtle social difficulties likely to adversely affect their ability to establish and maintain positive relationships with others. These difficulties need to be monitored alongside other potential neurodevelopmental concerns and parents supported to actively nurture child social competence.

ABSTRACT

OBJECTIVE: To examine the language development at corrected age 4 years of a regionally representative cohort of children born very preterm (VPT). Of particular interest was the identification of biological and socioenvironmental risk and protective factors that influence VPT children's early language development. METHOD: Data were collected as part of a prospective longitudinal study of 110 VPT (VPT: ≤ 33 weeks gestation) and 113 full-term children (full term: 37-41 weeks gestation) born in Canterbury, New Zealand from 1998 to 2000. At corrected age 4 years, all children were assessed with the preschool version of the Clinical Evaluation of Language Fundamentals. Extensive information was also collected about children's family social background, perinatal health, childrearing environment, education/intervention exposures, and neurodevelopmental progress from birth to age 4. RESULTS: At the age of 4 years, VPT children were characterized by poorer receptive and expressive language development than full-term children. These differences persisted after exclusion of children with neurosensory impairment as well as statistical adjustment for the effects of social risk. Within the VPT group, the key predictors of children's overall language development were family social risk at birth (p =.05), severity of white matter abnormalities on neonatal magnetic resonance imaging (p =.49), observed parent-child synchrony (p =.001), and concurrent child cognitive ability (p =.001). Together, these factors accounted for 45% of the variance in children's total Clinical Evaluation of Language Fundamentals-Preschool scores. CONCLUSION: By preschool age, children born VPT show early emerging mild to moderate language delays that are likely to affect their school success and longer-term developmental progress. Findings highlight the importance of potentially modifiable factors such as early brain injury and parenting quality in predicting the language outcomes of children born VPT.

ABSTRACT

BACKGROUND: Educational underachievement is a major morbidity associated with very preterm (VPT) birth. However, few studies have examined early school outcomes with most employing global, clinic based measures. OBJECTIVE: To examine the early school achievement in a cohort of children born VPT and studied to age 6 years. METHODS: A regional cohort of 102 VPT children (

ABSTRACT

This study examined the effects of being born very preterm on children's early language development using prospective longitudinal data from a representative regional cohort of 90 children born very preterm (gestational age <33 weeks and/or birth weight <1,500 grams) and a comparison sample of 102 children born full term (gestational age 38-41 weeks). The MacArthur-Bates Communicative Development Inventory: Words and Sentences (CDI-WS) was used to assess children's language development at age 2;0 (corrected for gestational age at birth). Clear linear relationships were found between gestational age at birth and later language outcomes, with decreasing gestational age being associated with poorer parent-reported language skills. Specifically, children born extremely preterm (<28 weeks' gestation) tended to perform less well than those born very preterm (28-32 weeks' gestation), who in turn performed worse than children born full term (38-41 weeks' gestation). This pattern of findings was evident across a range of outcomes spanning vocabulary size and quality of word use, as well as morphological and syntactic complexity. Importantly, associations between gestational age at birth and language outcomes persisted after statistical control for child and family factors correlated with both preterm birth and language development. These findings demonstrate the presence of pervasive delays in the early language development of children born very preterm. They also highlight the importance of gestational age in predicting later language risk in this population of infants.
