NPR (National Public Radio) may have gotten the title wrong, but the news article itself got the information correct. Click HERE to go to NPR's web page and listen to the radio broadcast.
This story is about research that looks at clusters of children diagnosed with autism and how they tend to occur in places where parents are older, more educated, and white. The study (U of California, Davis) found, and this is important to those who are convinced otherwise, there is no link to local pollution or chemical exposures. This particular result is important to all those parents that want to have all the "toxins" removed from their children, or who over protect them with fad diets and social isolation because they hear about "toxins" in the air, water and food.
The study results suggest that areas in California with apparently high rates of autism spectrum disorders are probably just places where parents are more likely to obtain a diagnosis for their child. In other words, they look like areas with high autism rates, but they are in fact the same as other areas of California, except the parents can afford medical care, psychologists and ....lawyers to help with school issues. And these are of course areas where parents have jobs that require higher education, and therefore ..... not much in the therefore area here. It's as simple as it sounds.
"It doesn't necessarily mean that higher education causes autism," says Irva Hertz-Picciotto, one of the study's authors and a researcher at the UC Davis MIND Institute. "It gets you the diagnosis more frequently."
The UC Davis study looked at the geographic distribution of about 10,000 children who were born in California from 1996 through 2000 and later diagnosed with an autism spectrum disorder. A "cluster" was defined as a community in which the proportion of children diagnosed with autism was at least 70 percent higher than in surrounding areas. 70%. That's pretty high, and tells you what money and education get for children. A diagnosis, and treatment! (This study should be done by the department of political sciences, with an action plan.)
The study found that differences in parents' age, education and ethnicity explained the cluster most of the time. It doesn't necessarily mean that higher education causes autism. Having parents with a higher education, and I suppose salary and better medical insurance, gets you the diagnosis more frequently. The study found that children of parents who finished college were at least four times more likely to be diagnosed than children of parents who didn't finish high school.Interestingly, children were also more likely to be diagnosed if they were born in a community near a regional service center for people with autism. (Some, I suppose, would think that living near a regional service center causes autism....but most of us get the point.)
The study may be most interesting because it did not find any environmental explanation for higher autism rates, says Steven Novella, a neurologist at Yale University and the author of the blogs "Neurologica," and "Science-Based Medicine." "You can't prove a negative," Novella says. But the results of this and other studies suggest that "if there are environmental factors, they're small."
The California results also show how widely autism diagnosis rates can vary from place to place, Novella says. In some areas of the state, children were four times as likely to be diagnosed as in other areas.That suggests that in many areas there are still a huge number of children with autism spectrum disorders who are slipping through the cracks, Novella says. I wonder how many, and what that says about us here in Canada, where the government won't pay for private practitioners..licensed and registered medical and psychological professionals.... to perform a diagnosis but instead put you on a long waiting list for Provincial services. (When is that going to change? WHY can't the government pay for a private practitioner to administer a diagnostic exam? Could it be a way to avoid paying for services for those they would diagnose? No, that couldn't possibly be it.)
This is a nice article, and it's an excellent way to look at what science tells us, and what it doesn't. As we always say, "correlation does not equal causation."
