Objective:

To clarify the association between maternal smoking and the risk of neurodevelopmental disorders in offspring, specifically intellectual disability, ASD, and ADHD.

Approach:

Key Findings:

• Maternal smoking is associated with an increased risk of neurodevelopmental disorders in offspring, particularly ADHD.
• The association with intellectual disability and ASD is less robust.
• Cumulative smoking exposure shows a dose-response relationship with neurodevelopmental outcomes.

Interpretation:

The findings suggest that maternal smoking is a significant modifiable risk factor for neurodevelopmental disorders, emphasizing the need for targeted smoking cessation strategies among pregnant women.

Limitations:

• The study relies on self-reported smoking status, which may introduce bias and affect the reliability of findings.
• Causal relationships cannot be definitively established due to the observational nature of the study.
• The inability to ascertain smoking status specifically during pregnancy limits the precision of exposure assessment.

Conclusion:

Addressing maternal smoking during pregnancy could be crucial in preventing neurodevelopmental disorders in children and should be a public health priority.
