Autism and Rainfall Linked, Study Suggests

In Health and Safety by Paul Martin1 Comment

A recent study has suggested that autism has a link to wetter climates, such as the United States’ Northwest.

There is some room for doubt, as autism diagnoses seem to be on the rise in all climates.

However, when plotted on a graph against daily precepitation reports, “Autism prevalence rates for school-aged children in California, Oregon and Washington in 2005 were positively related to the amount of precipitation these counties received from 1987 through 2001.”

The study was done based on autism rates from state and county agencies for children born in California, Oregon and Washington between 1987 and 1999.

While doctors agree that there is a genetic component to autism, many also believe that there could be an environmental effect that can trigger it as well.

The U.S. Centers for Disease Control and Prevention has launched a long-term study to find the causes of autism and other childhood conditions.

    While any studies to determine the cause of autism are needed, the inherent danger of these involves the emotions of parents. With any condition, as conjectures are made, it is easy to get caught up in the possibilities as opposed to what the actual findings might suggest. This particular study is very preliminary and does not suggest any findings consistent with other studies being done.
    Its important to note that this study does not directly suggest rainfall is the irritant, but part of it. It also suggests that rainfall causes children to play indoors where they are exposed more to household chemicals and toxins while decreasing their exposure to the sun and Vitamin D.
    Children’s Care Hospital and School practices evidence based medicine and desires to be a resource for parents as well as an advocate for children with autism. We strongly encourage all interested parties to be thoroughly versed in any studies before making a firm opinion. If you or someone you know suspects their child may have autism, have them tested/evaluated as soon as possible. Early intervention is the best method for assisting those with autism.
