Association between exposure to antibiotics during pregnancy or early infancy and risk of autism spectrum disorder, intellectual disorder, language disorder, and epilepsy in children: population based cohort study

Korean cohort study (n=1,961,744 children in pregnancy analysis; 1,609,774 in early infancy analysis) found antibiotic exposure during pregnancy or early infancy was not linked to increased risk of autism spectrum disorder, intellectual disorder, or language disorder.

SPS commentary:

The results generally remained consistent across several subgroup and sensitivity analyses, except for slightly elevated risks observed among children who used antibiotics during very early life and those who used antibiotics for more than 15 days.
