[Neurodevelopment of children born very preterm with extremely low and very low body weight].

AIM: To evaluate the characteristics of neurodevelopment by the age of 5-8 years in children who were born very preterm with extremely low body weight (ELBW) and very low body weight (VLBW).

MATERIAL AND

METHODS

Seventy-two patients, aged from 5 years to 8 years were examined. Patients were divided into group I (36 patients born preterm with ELBW (16 boys, 20 girls)) and group II (36 patients born with VLBW (16 boys, 20 girls)). The control group included 30 healthy peers (16 boys, 14 girls). All children were assessed by means of the Griffiths Mental Development Scales, Extended Revised: 2 to 8 years (GMDS-ER 2-8).

RESULTS

The value of general quotient (GQ) in patients born with ELBW (73.4±2.1) was significantly lower compared to their healthy peers (80.9±2.1; p=0.036). The same tendency was found in patients born with VLBW who's GQ was decreased by 73.1±3.0 (p=0.101). Concurrently the patients demonstrated lower scores on all six scales, which achieved significant difference with the controls for the 'Locomotor' and 'Performance' scales in group I, and for the 'Performance' and 'Practical reasoning' scales in group II. The boys born with ELBW tended to demonstrate lower results on all six scales and received significantly lower scores on the 'Locomotor' and 'Language' scales. The boys born with VLBW demonstrated significantly lower scores on the 'Language', 'Eye and hand co-ordination' and 'Practical reasoning' scales. In girls significantly lower score on the 'Performance' scale only was shown for those, who were born with ELBW.

CONCLUSION

Early diagnosis and characterization of developmental delays in children born very preterm determine the effectiveness of therapeutic measures based on the individual approach and comprehensive medical-psychological-pedagogical support.
