A new study from California, children with autism spectrum disorder were more likely to be mothers who lived near fields that deal with certain pesticides during pregnancy.The proximity of agricultural pesticides during pregnancy also joined other types of developmental delay among children.
"We need in the third study, in particular, the link with autism spectrum disorders have shown links between exposure to pesticides and more papers with developmental delay, says lead author Janie f. Shelton, University of California, Davis.
More research is needed before scientists say pesticides cause autism, she told Reuters Health in an email. But the pesticides affect the nervous system of signaling cells, he added, so the direct link is credible.
California has only a few States in the United States, where the agricultural use of pesticides is strictly reported and connected. The new study, the researchers used those maps to track exposures during pregnancy 970 children's mothers.
The children included a 486 with autism spectrum disorder (ASD) 168 developmental delay and typical development with 316.
Developmental delay, where the children will use the extra time to get to the communication, social and motor skills milestones, affects about four percent of US kids, the researchers write. The Centers for Disease Control and Prevention estimates that one in 68 children with ASD also have marked deficiencies in social interaction and language.
In the new study, about a third of mothers who lived within a radius of the fields most commonly treated with pesticides, Organophosphates.
Of mothers exposed to Organophosphates were 60 percent more likely to have an ASD than children-exposed mothers, the authors report in Environmental Health Perspectives.
Autism risk exposure was added to so-called "sensory bias of insecticides, because there was a risk of developmental delay. Carbamate pesticides, joined by developmental delay, but not broad-based.
Some pesticides exposure seemed to be the most important in the design and just prior to the third trimester, but for others, it seemed not to matter when during pregnancy, women were exposed to.
Dr. Philip j. Landrigan speculated that pesticides probably drifted from plants in the air, and it is how pregnant women were exposed to. The new study does not measure the maximum of pesticides in the air, however.
Landrigan is guided by the children's Environmental Health Center in Icahn's School of Medicine in New York at Mount Sinai, and was not involved in the new study.
"We knew we were already in the animal studies, as well as epidemiological studies of women's and children's exposure to birth (pesticides) is linked to lower IQ," Landrigan told Reuters Health. "This study is a continuation of, the use of the entire State population, looking at a number of different types of pesticides and find the template a broad association between exposure to pesticides and the development of disability."
In addition, in this study almost certainly underestimates the true strength of the association between pesticides and neurological problems, he said, because it is not just a measure of the exposure of each woman.
The registers of pesticides, such as in California, the one and the other in New York are rare, but are critical to public health efforts in this area, Landrigan said. Concerned parents to advocate for their registers in their countries, he added.
"The one lesson or message to parents is to minimize or eliminate the plant protection agents in their own homes," Landrigan said.
Months prior to and during pregnancy, it would be wise to avoid the application of pesticides in the home or on the grass, he said.
City-dwelling families instead of spraying for cockroaches every month, integrated pest management is the better option. The approach makes the chemical pesticides as a last resort – first steps to seal the cracks and crevices in the clean up of food residue and then try a relatively non-toxic alternatives, such as Roach Motels.
"If there's one thing that parents can control is what will become of his house," he said.
"Would be a good first step to stop the Organophosphates and pyrethroids inside the" Shelton agreed.
Comment:Information and studies of pesticides such as Organophosphates and pyrthroids, causing developmental delays, ADHD, and autism is not new. The information has been for years! It seems that if toxic chemicals (pesticides) affect the Neurology of bugs (thus killing them), these same combat unintentionally affect the neurological function of children, too. Looks simple enough, back in the year 2010, the Harvard study blamed the pesticides found in the urine of children with ADHD. The study was conducted over 4 years ago! Even if the information is on the increase in serious neurological effects of pesticides, in particular of children, the use of pesticides in agriculture in the United States continues to grow! It is safe to say that Big Ag in America does not want you to worry about pesticides:
