Insights
Very low birth weight preterm infants show delayed cognitive and expressive language development compared to term infants. These delays persist beyond infancy, highlighting the need for early intervention.
Area of Science:
- Developmental Pediatrics
- Neuroscience
- Speech-Language Pathology
Background:
- Very low birth weight (VLBW) preterm infants are at risk for developmental delays.
- Cognitive and expressive language development are crucial areas affected by preterm birth.
Purpose of the Study:
- To compare the cognitive and expressive language development of VLBW preterm infants with term infants.
- To identify the developmental trajectory and timing of delays in VLBW infants.
Main Methods:
- Longitudinal study involving monthly evaluations of 12 VLBW preterm infants and 20 term infants.
- Utilized the Protocol for Expressive Language and Cognition Development Observation (PELCDO).
- Videotaped sessions and analyzed data according to the PELCDO protocol.
Main Results:
- VLBW preterm infants demonstrated significantly later development in cognition and expressive language compared to term infants.
- Positive correlations were observed between cognitive and expressive language development.
- Developmental delays became more pronounced after 6 months of age, extending through the sensorimotor and into the preoperational periods.
Conclusions:
- Cognitive and expressive language delays are significant in VLBW preterm infants.
- Continuous follow-up evaluations are essential for these infants.
- Identifying the optimal timing for speech-language intervention is crucial for addressing these developmental needs.
Abstract:
The performance of very low birth weight preterm infants, in terms of cognition and expressive language, was analyzed and compared with that of term infants with the Protocol for Expressive Language and Cognition Development Observation (PELCDO). The study involved 12 very low birth weight preterm infants and 20 term infants, all of whom were evaluated monthly. Sessions were videotaped, and data were analyzed according to this specific protocol. Our results suggest that cognition and expressive language develop significantly later in very low birth weight preterm infants than in the term. We found positive correlations for cognitive and expressive language development, the delay becoming more evident after 6 months of age, persisting through the sensorimotor period, and continuing into the beginning of preoperational period, indicating the importance of follow-up evaluation, defining the true needs of such infants and identifying the ideal moment for speech-language intervention.
