Prenatal alcohol use as a risk for attention-deficit/hyperactivity disorder

Area of Science:

• Perinatal mental health
• Child developmental psychology
• Public health

Background:

• Maternal alcohol consumption during pregnancy is a known risk factor for adverse child outcomes.
• The specific association between patterns of alcohol use and childhood mental disorders requires further investigation.
• Longitudinal studies are crucial for understanding the long-term effects of prenatal exposures.

Purpose of the Study:

• To investigate the association between maternal alcohol use during pregnancy and the development of mental disorders in offspring.
• To control for confounding risk factors in a longitudinal study design.
• To specifically examine the link between prenatal alcohol exposure and attention-deficit/hyperactivity disorder (ADHD).

Main Methods:

• A longitudinal study followed 81 mother-child pairs from pregnancy for 12 years.
• Maternal alcohol use was assessed during pregnancy using questionnaires and interviews.
• Child mental disorders, including ADHD, were evaluated using the Kiddie Schedule for Affective Disorders and Schizophrenia for School-Age Children-Present and Lifetime Version (K-SADS-PL).

Main Results:

• Binge drinking or low-moderate alcohol consumption throughout pregnancy was associated with a fivefold increased odds of childhood ADHD.
• The combination of binge drinking and regular low-moderate alcohol use increased ADHD occurrence variance by 19%.
• Episodic heavy drinking (≥4 drinks) or regular low-moderate drinking during pregnancy significantly elevated ADHD risk.

Conclusions:

• Maternal alcohol use, particularly binge drinking and consistent low-moderate consumption, is significantly associated with an increased risk of ADHD in children.
• Interventions aimed at reducing alcohol consumption in pregnant women could potentially decrease the incidence of ADHD in offspring.
• These findings underscore the importance of prenatal alcohol abstinence for child neurodevelopmental health.
