Hyperbilirubinemia and Language Delay in Premature Infants

2009

Objective To evaluate if language delay at three years in premature infants is associated with prior exposure to hyperbilirubinemia during the first two weeks after birth. Patients and Methods We performed retrospective case-control study of infants admitted to the Neonatal Intensive Care Unit between January and October 2003. Inclusion criteria included a birth weight ≤ 1500 grams and follow-up to age three years. Exclusion criteria included genetic disorders and hearing loss or recurrent ear infections. Peak total serum bilirubin (TSB) during the first two weeks and duration of hyperbilirubinemia (days with TSB > 8 mg/dl) were determined. Infants with language delay and receiving speech therapy by three years were identified through developmental clinic charts and tracking program and compared to infants who had normal language development. Results 125 infants with birth weight ≤ 1500 grams were admitted to the Neonatal Intensive Care Unit between January and October 2003. Fifteen infants died and 110 were discharged home. 102/110 (93%) of infants had follow-up to age three years. Four infants were excluded (1 genetic disorder, 3 delayed hearing loss or recurrent ear infections). 24 infants had a language delay and received speech therapy while 74 infants had normal language development. There was no significant difference in peak TSB and duration of hyperbilirubinemia between the two groups. On logistic regression, only bronchopulmonary dysplasia was associated with language delay (Adjusted odds ratio 7.3, 95% confidence interval 2.5 – 22). Conclusions Hyperbilirubinemia defined as peak TSB level or duration of elevated bilirubin in days is not associated with language delay in premature infants. However, this issue deserves investigation since other measures of bilirubin, such as unbound bilirubin may be associated with language delay.

Preterm Birth: Neuropsychological Profiles and Atypical Developmental Pathways

Preterm birth is characterized by multiple interacting atypical constraints affecting different aspects of neuropsychological development. In the first years of life, perceptual, motor, and communicative-linguistic abilities, as well as attention, processing speed, and memory are affected by preterm birth resulting in cascading effects on later development. From school age to adolescence, a catch-up of simpler competencies (i.e., receptive lexicon) along with a more selective effect on more complex competencies (i.e., complex linguistic functions, math, motor, and executive functions) are observed, as well as a relevant incidence of behavioral outcomes. A wide heterogeneity in preterm children's neuropsychological profiles is described depending on the interaction among the degree of neonatal immaturity, medical complications, neurological damages/alterations, environmental and social factors. Severe neuromotor and sensory damages are not frequent, while low severity impairments are common among preterm children. It is argued that developmental pathways of preterm children are atypical, and not merely delayed, and are characterized by different developmental patterns and relationships among competencies.

“…A longitudinal study has shown that preterms at risk for lexical and grammatical problems in the first years of life had several delays (34%) on reading at age 7; 0 (Crunelle et al, 2003). Notwithstanding the relevance of this field of research, relationships between language and literacy have not been investigated in at-risk populations, such as preterm children, except for two studies.…”

“…Although not completely concordant in their results, these studies revealed that the preterm population in general did not differ from full-term children in lexical production, but some difficulties characterised preterms with greater immaturity (birthweight f1000 grams or gestational age f32 weeks). Preterms have been found to have a shorter mean length of utterance (MLU) at age 2 ; 6 (in preterms with greater immaturity ; Sansavini et al, 2006), at age 3 ; 6 (Sansavini, Guarini, Alessandroni, Faldella, Giovanelli & Salvioli, 2007) and at age 5 ; 0 (Crunelle, Le Normand & Delfosse, 2003). The results found in the first years of life and until school age highlighted how preterm birth may similarly affect lexical development across different languages.…”

Long-term effects of preterm birth on language and literacy at eight years

et al. 2009

View full text Add to dashboard Cite

The aims of this study were to investigate whether specific linguistic difficulties in preterm children persist at eight years and to examine the interrelationships between language and literacy in this population, compared with a control group of full-term children. Sixty-eight monolingual Italian preterms and 26 chronologically matched controls were recruited. Language (grammar comprehension, lexical production and phonological awareness), literacy (reading comprehension, reading and writing) and general cognitive development were investigated. Results showed no general delay in preterms, but slight difficulties in specific linguistic abilities (grammar, lexicon, phoneme synthesis and deletion of the first syllable), more difficulties in literacy (speed in reading and accuracy in writing) and certain correlations among competencies turning out to be different from the control group. In conclusion, our study established that a partially atypical trajectory emerged in preterms, showing specific long-term effects of preterm birth on language and literacy development.
