A Case for Early Screening: Prenatal Alcohol Risk Exposure Predicts Risk for Early Childhood Communication Delays.

Area of Science:

• Neurodevelopmental Pediatrics
• Obstetrics and Gynecology
• Public Health

Background:

• Prenatal alcohol exposure (PAE) is a known cause of developmental deficits.
• The predictive ability of prenatal alcohol risk (PAR) screening tools for neurodevelopmental outcomes remains understudied.
• Early identification of communication delays is crucial for timely intervention.

Purpose of the Study:

• To determine if PAR screening predicts communication development in children at 12, 24, and 36 months of age.
• To assess the association between PAR screening results and the risk of communication delays.
• To evaluate the utility of PAR screening in early childhood developmental surveillance.

Main Methods:

• Analysis of data from 772 mother-child pairs in the All Our Families pregnancy cohort.
• Utilized the T-ACE tool for validated screening of PAR.
• Assessed child communication development using the Ages and Stages Questionnaire, Third Edition.
• Employed logistic regression to calculate odds ratios and 95% confidence intervals.

Main Results:

• A positive PAR screen was associated with a 1.5-fold increased risk of communication delay at 12, 24, and 36 months, independent of demographic factors.
• Significant differences in communication delay risk prevalence were observed between 12 and 24 months, and 24 and 36 months.
• Children at 24 months exhibited the highest risk for communication delays.

Conclusions:

• PAR screening during pregnancy can identify infants at elevated risk for communication delays.
• These findings support the integration of PAR screening into routine prenatal care to inform early developmental screening.
• Early identification via PAR screening may facilitate timely interventions for at-risk children.
