Fetal alcohol spectrum disorders--a case-control study from India

Area of Science:

• Neuroscience
• Developmental Pediatrics
• Public Health

Background:

• Maternal alcohol consumption during pregnancy is a significant risk factor for fetal neurotoxicity.
• This exposure can lead to Fetal Alcohol Spectrum Disorder (FASD), characterized by a range of developmental issues.
• Understanding the specific neurobehavioral consequences is crucial for early intervention and support.

Purpose of the Study:

• To compare clinical features and neurobehavioral outcomes in children with prenatal alcohol exposure versus controls.
• To identify specific anomalies and functional deficits associated with in utero alcohol exposure.

Main Methods:

• A cohort of 26 children with in utero alcohol exposure was compared to 27 age- and sex-matched controls.
• Assessments included Fetal Alcohol Syndrome (FAS) facial features, minor physical anomalies (MPAs), anthropometry, behavioral problems (Childhood Behavior Checklist), and intellectual functioning.
• Statistical analysis was performed to determine significant differences between the exposed and control groups.

Main Results:

• Minor physical anomalies (MPAs) were significantly more prevalent in the alcohol-exposed group (p=0.001).
• Philtrum smoothness was the only significant facial feature difference (p=0.001).
• Children exposed to alcohol exhibited more pronounced behavioral problems (p=0.001) and significantly poorer intellectual functioning (p=0.001) compared to controls.

Conclusions:

• Prenatal alcohol exposure is associated with a range of neurobehavioral problems in children.
• These findings highlight the persistent impact of alcohol on fetal neurodevelopment.
• Potential confounding factors, such as malnutrition, may influence clinical presentations.
