[Neurologic evolution of children of low birth weight]
Insights
This study followed 129 low birth weight children for up to 9 years, assessing neurological development and correlating it with developmental quotients to understand prematurity impacts.
Area of Science:
- Pediatrics
- Neuropediatrics
- Developmental Psychology
Context:
- Prematurity and low birth weight remain significant pediatric challenges.
- Etiology involves complex genetic and intrauterine environmental factors.
- Longitudinal studies are crucial for understanding developmental trajectories.
Purpose:
- To investigate the neurological evolution and developmental outcomes in low birth weight children.
- To correlate neurological development with developmental quotients (DQ) using Gesell's tests.
- To examine the "continuum of lesion" hypothesis in this cohort.
Summary:
- A 9-year study followed 129 low birth weight infants (categorized by weight) up to age 9.
- Neurological assessments were performed using standardized methods.
- Results were correlated with DQ derived from Gesell's tests to analyze developmental progression.
Impact:
- Provides insights into the long-term neurological and developmental consequences of low birth weight.
- Contributes to understanding the "continuum of lesion" in pediatric neurology.
- Informs clinical practice for managing and supporting children born with low birth weight.
Abstract:
The prematurity is still an important problem for either pediatricians and neuropediatricinas. All the mechanisms that can produce lowbirth weight, are not known, although many of them are related to genetics and environmental intra-uterine factors. Having in mind tha study of the development of such type of children, a group of investigators has been working for 9 years now, envolving aspects related to the Pediatry, Social Pediatry, Neuropediatry, Psychiatry, Otorhynolaringology, Ophtalmology and Odontology. In this study they are trying to envolve all the possible aspects on growth and development of children with lowbirth weight. In 189 children, 129 were followed during several years. Most of them were observed up to 5 years of age and few of them up to 9 years of age. The children were divided into three groups as follow: Group I-Children with weights under 1.750 g; Group II-Children with weights between 1.751 and 2.000 g; Group III-Children with weights over 2.001 g and under 2.500 g. The neurol-gical tests were done according to the used system at the Neurologic Clinic of the Faculty of Medicine (University of São Paulo). The present work starts with a general revision on the most important existent papers on the prematures neurological evolution. After presenting his own results, the authors make a correlaction of the neurologic evolution with the developmental quotient (DQ), which were gotten through Gesell's tests and its variations, in order to verify the existence of what is known as "continuum of lesion" of Knobloch and col.
