A mother’s caffeine consumption during pregnancy does not appear to have any clinically significant effect on her child’s IQ or problem behaviors, this is according to a prospective cohort published in the American Journal of Epidemiology.
Although caffeine is more commonly consumed during pregnancy, there are a few reports on the association of in utero caffeine exposure with offspring cognition or behaviour during childhood. After a series of study, it was concluded that they was no meaningful association of serum paraxanthine level (a caffeine metabolite) with childhood IQ or problem behaviours
Women who are pregnant should not however be careless about caffeine consumption. Moderation is key!
