Correlation or causation?
A Danish study simply links the two. See PhysOrg: Newborns with jaundice more likely to develop autism: study
My first reaction is that this is an example of correlation and there's nothing here to indicate a shared causal agent in autism and jaundice.
Except for this part: "the risk of autism was higher... if the child was born between October and March."
Is this another argument for Vitamin D? Research is indicating this vitamin is a super-agent for health. Hopefully further studies of the jaundice-autism link will be forthcoming.
