ADHD Linked to Pesticide Exposure

Chemicals on our produce may contribute to behavior problems in our kids, suggest three new studies. The studies, which looked at a class of pesticides called organophosphates (OP), linked exposure to the chemicals with attention disorders in children, with perhaps the most dramatic impacts to kids who are exposed in the womb and those who are genetically most susceptible. Because pesticide residues linger on fruits and vegetables, the findings suggest that people either buy organic or take the time to wash their produce well.

Organophosphates are a set of common pesticides that work by attacking the nervous systems of insects. When people are exposed to high levels of the chemicals, they can develop anxiety, confusion impaired concentration, and other serious symptoms. More recently, scientists have started to wonder how chronic exposure at low levels might be affecting people, especially kids, whose nervous systems are still developing.

1 in 100 Children Have Autism

Two new government studies indicate about 1 in 100 children have autism disorders – higher than a previous U.S. estimate of 1 in 150.

The new estimate would mean about 673,000 American children have autism. Previous estimates put the number at about 560,000.

President Barack Obama has made autism a priority for research, Insel said. Federal stimulus money has been earmarked for autism, and a 2006 law pumped millions of dollars of new federal money into autism research, screening and treatment.

TV and Your Child

Scientific evidence suggests that using the boob tube as a babysitter has its price: the more time babies spend sitting in front of the screen, the more their social, cognitive and language development may suffer. Recent studies show that TV-viewing tends to decrease babies' likelihood of learning new words, talking, playing and otherwise interacting with others.

Many studies have suggested that television impedes learning by inhibiting youngsters' ability to interact with others, and according to Dr. Dimitri Christakis, a University of Washington pediatrician, that effect may be compounded when parents get drawn into TV-watching too.

Television by nature is a passive medium that hampers rich social interaction. When the TV is switched on, youngsters spend more time in silence and solitude than they do in active social interaction. In 30% of American households, the television is on most of the day, regardless of whether anyone is watching.
