pollution and stress linked to child asthma - indoor air cleaner
There may be a reason why children in the United States have such a high incidence of asthma. S. urban areas.
Young people under pressure
According to a study in the National Academy of Sciences journal, out-of-home parents and exposure to air pollution have a higher risk of asthma.
"New research has put forward some questions about why stressplus-
The problem caused by pollution is more serious than anyone else . "
Harold Faber, associate professor of pediatric lung at Houston Baylor College of Medicine and Texas Children's Hospital, is the author of controlling your child's asthma.
"Why is this combination more toxic than any one alone? "City-dwelling U. S.
Compared with peers living elsewhere, the risk of asthma in children is about 22-45 higher. (
About 22 million people in the United States have asthma, including 6 million children. About 2.
4 million Canadians, including nearly 600,000 children, have asthma. )
In this new study, Dr.
Rob McConnell, professor of preventive medicine at the University of Southern California's Keke Institute of Medicine in Los Angeles, tracked 2,497 children in the area.
These children are between 5 and 9 years old and have no history of asthma or breathing.
Children under pressure
Parents living in a busy area
Associated pollution is at a higher risk of developing asthma in these three years
Children without parental pressure have a one-year study period.
The researchers did not measure stress levels in children.
If parents say that their lives are unpredictable, uncontrollable and overwhelming, they will be considered stressful.
Air pollutants can cause airway inflammation, which is a major feature of asthma.
Stress may reduce the function of the immune system, or affect the autonomic nervous system, which helps regulate breathing, the authors say.
Farber said the study helped identify children with the greatest risk of respiratory diseases, and he was not involved in the new study.
"It's important to manage stress and pollution, and if two things happen at the same time, it's important above them.
"In addition, the study found that parental stress also appears to have exacerbated the effects of smoking by mothers during pregnancy.
Exposed to cigarette smoke in the womb, children whose parents are under pressure --
Children out there are two to three times more likely to develop asthma than children exposed to cigarette smoke alone.
Pressure and low socio-economic conditions (
If not completed in high school)
They themselves did not increase their children's risk of developing asthma.
Farber recommends that if your child has any signs or symptoms of asthma-such as chronic cough or breathing-check it out as soon as possible.
"If you think your child is prone to asthma, don't live near the highway.
If you do live near the highway, overcome your stress and look at the stress management plan and/or move. " Dr.
Neil shacht, director of respiratory care at Mount Sinai Medical Center in New York, and author of a good doctor's guide to colds and flu, agrees.
"Individual stress does not cause or aggravate asthma unless it is combined with other known risk factors such as traffic --
Related air pollution, "he said.
"If a child lives in the country and is not exposed to air pollution, the stress of the parents will not make the situation worse.
"You can go to a green place," he said . ".
"Use a household air purifier to remove small particles from the air.
You may not be able to control outdoor air quality on your own, but you can try to control your indoor air quality by banning smoking indoors and choosing green cleaning products, does not contain chemicals that affect indoor air quality.
