Are Non-Stick Chemicals And Aging Dads More Dangerous To Babies Than Cocaine?

Last week the New York Times printed good news about a worrisome issue in childhood development. As it turns out, children whose mothers used cocaine during pregnancy have only slightly lower IQ scores than children whose mothers didn’t use. The difference between the children’s scores was so low it was deemed “scientifically insignificant.” In fact, the effect of alcohol on the fetus is more detrimental than cocaine’s, while tobacco’s is about the same.

But potential parents have some other science to consider this week. In the latest issue of Human Reproduction scientists found that women with higher levels of perfluorinated chemicals (PFCs, or the chemicals that make products “non-stick”) in their blood had more trouble getting pregnant. Women with higher levels of the two main chemicals—PFOA and PFOS—were up to 154 percent more likely to be infertile. Exposure is a particular problem for developed countries like the US, where eight percent of women of childbearing age have consulted a doctor about infertility. And, like we’ve said before, Teflon is forever.Also this month, the February issue of Scientific American notes that while the risks and difficulties for mothers over 40 and their babies have long been studied, journalist Paul Raeburn points out that babies born to men over 40 are six times more likely to have autism and twice as likely to have schizophrenia than babies whose fathers are under 30. For fathers age 50 and older, the risk of having an autistic child increases to nine times the rate of fathers under 30.
In other words, “A 40-year-old man’s risk of having a child with schizophrenia is the same as a 40-year-old woman’s risk of having a child with Down syndrome,” says Raeburn. Looks like it’s time to stop pinning women with the blame for a baby’s health.

We've never been very good at being conservative.

And usually, that serves us well in doing the ambitious, hard-hitting journalism that you turn to Mother Jones for. But it also means we can't afford to come up short when it comes to scratching together the funds it takes to keep our team firing on all cylinders, and the truth is, we finished our budgeting cycle on June 30 about $100,000 short of our online goal.

This is no time to come up short. It's time to fight like hell, as our namesake would tell us to do, for a democracy where minority rule cannot impose an extreme agenda, where facts matter, and where accountability has a chance at the polls and in the press. If you value our reporting and you can right now, please help us dig out of the $100,000 hole we're starting our new budgeting cycle in with an always-needed and always-appreciated donation today.
