Maternal smoking is a modifiable risk factor linked to adverse neurodevelopmental outcomes in offspring, including ADHD, ASD, and intellectual disability.
2

The study utilized a large nationwide cohort of over 860,000 mother-child pairs from Korea to investigate the impact of maternal smoking on neurodevelopment.
3

Maternal smoking status was assessed through health examination records, allowing for a more accurate evaluation of smoking exposure compared to previous studies.
