Where in the study is it shown that 18-19 year old moms have a higher risk of proving babies with autism than 40+ moms? Because I'm not seeing it.

Did the presser just make it up?

Doesn't make sense to me...

Parents over 40 have an increased risk of producing children with Down Syndrome, not Autism.

>There was a joint effect of maternal and paternal age with increasing risk of ASD for couples with increasing differences in parental ages.
Breeding with non-age peers is positively correlated with autism, and under-20 preggos are slightly more likely to have been knocked up by a non-age peer.

source? guessing this was mainly due to socioeconomic differences between cohorts < 20 and over, access to medical care, diets, etc

Source for the greentext is the abstract of the Nature article in OP's link, it's the sentence cut off in the screenshot in >>15848180. The rest of it was revealed to me in a dream.

No, it's assortative mating. Autists, or more precisely, people with the broader autism phenotype, are more likely to breed with non-age peers because they select mates who also have the broader autism phenotype. Being selective on that trait makes them (us, although in my case I married an age-peer) less selective on age.
