[Evaluation of some aspects of the acquisition and development of language in pre-term born children].
The correction of the age of pre-term infants for the motor evaluation has been the accepted practice but it has not been clear in other areas. This study compared indicators of the acquisition and development of language, considering corrected and chronological ages. Twenty healthy infants born between the 28th and 36th week of gestation (median 32 weeks), weighing 800g to 2380g (median 1590g), 9 AGA and 11 SGA, were followed up to 15 months age. As a reference for normality, evaluation of Costa et al. (1992) was used, which groups predictable behavior in 5 levels. For receptive language, considering the chronological age, normal performance occurred at all levels except for Level I (0-3 months). For expressive language, considering the chronological age, 6 (12%) of the 50 evaluations showed normal performance. With their age corrected, in 16 evaluations (40%) the infants achieved the expected level, mainly at 6 and 12 months age. On the whole, for the chronological age, there was a larger number of AGA with normal performance (p<0.05). We conclude that with the use of the Costa method, it was unnecessary to correct the age for receptive language evaluation, and that, for the expressive, the high frequency of normal results at the corrected ages for 6 and 12 months, suggests that these ages constitute periods of intensification of vigilance.
