Is there any difference between high-risk infants with different birth weight and gestational age in neurodevelopmental characters?

Abstract

Aim: This study is aimed to investigate differences between cognitive, language and motor development of high-risk infants related to birth weight and gestational age. Material and Methods:One hundred sixty high-risk infants who were born 32 weeks, 1 500 gr and below included in this study. According to corrected age, 58 infants were 1 month, 72 were at 4 months, 82 were at 8 months and 65 were 12 months old. Infants were seperated two groups according to gestational age <30 weeks and 30-32 weeks and birth weight ≤1 000 gr and 1 001-1 500 gr. Infants motor development were assessed with Bayley-III Infant and Toddler Development Motor Scale (Bayley-III) and Neuro Sensory Motor Developmental Scale (NSMDA), cognitif and lanuage development were Bayley-III cognitive and Language scales. Assessments were applied by the same physiotherapist at 1 month, 4 months, 8 months and 12 months old infants in corrected age. Mann-Whitney U Test, 2 x 2 Chi-Square test ve Fisher's exact tests were used to compare group data. Statistical significance was determined p<0.05. Results:Cognitive, motor and language developments were in normal ranges in all infants. There were no statistical differences in cognitive, language and motor development between groups (p>0.05). Conclusion:Results of this study showed that the motor, cognitive and language development were normal in all high risk infants and power gestational age and birth weight did not affect these parametes.

Habilidades do desenvolvimento de crianças prematuras de baixo peso e muito baixo peso

“…Some studies have reported that infants born premature present significantly lower scores on language tests compared with those of children born full term (2,4,9,13,18,20,22,24) and that there is correlation between GA and birth weight and altered language development (2,4,9) . A study did not find differences in the performance of infants born preterm and full term regarding language, cognition, and motor development (12) . It is worth noting that the studies that addressed the development of language skills in preterm infants emphasized that although delay in language development is a frequent condition, variability is observed even in the absence of deficiencies and interference of socioeconomic status (12,14,28) .…”

Individuals born preterm with LBW and VLBW, despite the high probability of changes in development, do not constitute a homogeneous group.…”

“…However, the nature of these deficits is not yet fully understood (11,12) considering the multiple variables involved as a result of pre-, peri-and post-natal intercurrences, GA, birth weight, intensive care management, socioeconomic and environmental factors, and the complex process subsequent to the maturational development of the infant's brain, interfering with the trajectory of typical development (3)(4)(5)13,14) . Child development is based on domains of functions related to motor, cognitive and linguistic aspects, influenced by biological, psychosocial and environmental factors (15) .…”

The Effects of Birth Weight Index on Motor, Cognitive Function and Relationship with Some Personality Characteristics of Children

“…The motor development of preterm infants and very low weight and also the results of studies on motor and cognitive development of such children indicate that premature infants appear to be physically normal, but they have significantly lower motor functional and cognitive performance than their peers [9][10][11]. However, some results showed that there was no difference in motor function between the premature children and normal children [12,13]. Therefore assessment of motor domain is not only for understanding and to promote the aspects of development but also to understand the possible delay and improve the instrument in this domain [14].…”

Habilidades do desenvolvimento infantil de crianças nascidas com prematuridade extrema, acentuada e moderada na faixa etária 0 a 24 meses

“…intercorrências maternas ou perinatais, dentre outras (PÁEZ-PINEDA; VALENCIA-VALENCIA; ORTIZ-CALDERON, 2014;COELHO et al, 2016;IONIO et al, 2016;MELLO et al, 2016;ZAMBRANA et al, 2016;ADHIKARI;RAO, 2017;GASPARINI et al, 2017;MILNER et al, 2017;SANCHES-JOYA et al, 2017;KILLEEN et al, 2017). Alguns estudos tiveram na sua casuística prematuros nascidos abaixo de 32 semanas de IG, ou seja, a casuística era composta por prematuro extremos e acentuados, associados ou não a outras variáveis (KARA et al, 2015;LINSELL et al, 2015;VELIKOS et al, 2015;WONG et al, 2016); outros, com crianças nascidas abaixo de 35 semanas de IG e baixo peso (MAGALHÃES et al, 2011) KARA et al, 2015;BENASSI et al, 2016;PAREKH et al, 2016;RIBEIRO et al, 2016;PÉRES-PEREIRA et al, 2016;TAYLOR;CLARCK, 2016;ZAMBRANA et al, 2016;JOHNSON et al, 2017;KILLEEN et al, 2017;GASPARINI et al, 2017;PUTNICK et al, 2017;SANCHES-JOYA et al, 2017;SYNNES et al, 2017;YAARI et al, 2017), com a utilização de vários instrumentos voltados para este fim.
