Insights
Autism Spectrum Disorder (ASD) affects 9.1% of infants with NICU stays. Risk factors include prematurity and respiratory support needs, highlighting the need for early screening in high-risk infants.
Area of Science:
- Pediatric Neurology
- Developmental Pediatrics
- Neonatal Medicine
Background:
- Autism Spectrum Disorder (ASD) is a complex neurodevelopmental condition.
- Infants and children admitted to the Neonatal Intensive Care Unit (NICU) may face increased risks.
- Identifying early indicators and risk factors for ASD in this population is crucial.
Purpose of the Study:
- To determine the prevalence of ASD in children with a history of NICU admission.
- To identify significant risk factors associated with ASD development in this cohort.
- To explore neurophysiological markers using Auditory Brain Response (ABR) in relation to ASD.
Main Methods:
- A cross-sectional study involving 66 pediatric outpatients under 3 years old with prior NICU admission.
- Utilized the Childhood Autism Rating Scale-Second Edition (CARS-2St) questionnaire for ASD assessment.
- Employed Auditory Brain Response (ABR) testing to evaluate auditory pathway function.
Main Results:
- The prevalence of ASD was found to be 9.1% (6 out of 66 children).
- Significant risk factors included premature rupture of membranes, prematurity, extended NICU stay duration, and need for respiratory support.
- ABR testing revealed significantly increased latencies and intervals in children with ASD, indicating auditory pathway abnormalities.
Conclusions:
- The study highlights a notable prevalence of ASD among children with a NICU history.
- Early screening for ASD is recommended for infants and children with NICU admission, even without other apparent neurological signs.
- Findings support further research into neurophysiological markers for early ASD detection in at-risk infants.
Background And Objective:
Autism Spectrum Disorder (ASD) is a diverse neurodevelopmental condition. This study aimed to highlight the prevalence and risk factors associated with the development of ASD in infants and children who have been admitted to the NICU.
Methods:
A cross-sectional study was conducted on 66 pediatric outpatient clinic infants and children <3 years of age with a history of admission to NICU. CARS-2St questionnaire and Auditory brain response (ABR) were used.
Results:
The percentage of ASD was 9.1% (6/66) and the mean total CARS-2-St-test score of ASD vs non-ASD cases was 35 ± 2.7 vs 18.58 ± 2.74, p = 0.001. Significant risk factors for ASD included premature rupture of membranes (p = 0.001), prematurity (p = 0.002), longer duration of admission (p = 0.038), and increased need for respiratory support (p = 0.034). The mean values of the absolute latencies of ABR waves III, IV, and V and the I-III and I-V intervals of the right and left ear were significantly increased in those with ASD.
Conclusions:
This study is exploratory and hypothesis-generating and highlights the importance of screening infants and children with a history of admission to NICU who have an increased risk of ASD, and should be screened even if they have no other neurological manifestations.
