Resumen
This thesis aimed to evaluate the possible relationship between maturation of the auditory
pathway, language acquisition and the presence of psychological risk in preterm infants and
term. It was also analyzed the possible relationship between maturation of the auditory
pathway and language acquisition in late preterm infants and term to describe auditory
pathway maturation patterns of these babies, analyze the possible relationship between
maturation of the auditory pathway and psychological risk. This is a cohort study, longitudinal,
in which linked variables were compared to hearing and language of 0-12 babies. The
research population was composed of late preterm infants and term without neurological
injury or obvious organic syndrome. The sample consisted of 54 babies, being 17 babies
from the late preterm group and 37 babies from the group born at term from the study 2, and
31 babies composed the no risk group and 23 babies with psychic risk from study 3. The
families went through initial and continuing interviews to collect data on pregnancy, birth,
food, among others. Hearing maturation was assessed by analysis of Cortical Auditory
Evoked Potentials in the first, sixth and twelfth month. The gathering sessions were filmed at
3, 6, 9 and 12 months for analysis and checking of some of the protocols used. To verify the
psychological risk, evaluations were conducted using IRDIS and PRÈAUT questiionnaries.
To verify the language acquisition, evaluations used Language Acquisition Enunciation Sign,
DENVER II and Vocabulary Checklist. All aspects were evaluated on the day of collection
and subsequently confirmed by the filming. Analyzing the evaluations, it was found that in all
groups there was a statistically significant hearing maturation. Preterm babies showed
greater maturity than those born at term, due to its higher latency at birth and at 6 months. In
the evaluation of 12 months, it was observed equivalent results. As for the language, it was
observed that late preterm infants had lower performance in DENVER II in Phase 4.
Regarding the Language Acquisition Enunciation Sign, which evaluates the mother-infant
interaction, in Phase 1 there wasn't statistically significant difference between the groups in
favor of the group born at term as expected. As for the test Vocabulary Checklist, it was
observed that the term infants showed better understanding of vocabulary at 12 months.
Analyzing the auditory maturation and psychological risk, infants with greater psychological
risk also had higher latencies. In this sample, there was a higher concentration of risk with
babies in Phase I of IRDlS (42.59%, n = 23) and lower concentrations in Phase IV (14.81%,
n = 8). In assessing the PRÈAUT at 4 months, 42.59% (n = 23) of the babies were at risk and
9 months only 20.37% (n = 11). Finally, there is the importance for clinical practice, the
auditory maturation of monitoring and the development of listening skills of children who
show biohazardous and / or environmental risk, such as prematurity, especially extreme
cases, as well as the psychic risk.
