Among perinatal factors, only the Apgar score is associated with specific language impairment

Area of Science:

• Pediatric Neurology
• Developmental Psychology
• Speech-Language Pathology

Background:

• Specific Language Impairment (SLI) affects a significant number of children, impacting their academic and social development.
• Perinatal factors are increasingly recognized as potential contributors to neurodevelopmental disorders.

Purpose of the Study:

• To investigate the relationship between perinatal risk factors and the subsequent development of Specific Language Impairment (SLI).
• To identify specific perinatal characteristics that may be associated with SLI in children.

Main Methods:

• A case-control study design was employed, matching 179 children with SLI from special needs schools with 179 unaffected children from mainstream schools.
• Data on gestational age, birthweight, delivery complications, birth characteristics, and Apgar scores were collected from health records.
• The study included children aged 4-13 years, with a balanced representation of males and females.

Main Results:

• No statistically significant differences were found in gestational age or birthweight between children with SLI and the control group.
• Apgar scores at 1 and 5 minutes were significantly lower in children with SLI compared to controls (p=0.045 and p=0.001, respectively).
• The difference in Apgar scores between groups was more pronounced in females than in males, indicating a significant sex interaction (p=0.049 and p=0.043 for 1- and 5-minute scores, respectively).

Conclusions:

• Apgar scores emerge as a potential perinatal predictor for SLI.
• The findings suggest that the interplay between Apgar scores and sex may be crucial for understanding the causal pathways of SLI.
• These results could inform predictive modeling for SLI and guide future research into its etiology.
