Asthma is a chronic lung disease that continues to be a health asthma and airpollution in California, the United States and many other countries around the world. Asthma and airpollution can make breathing difficult and trigger coughing, asthma and airpollution, wheezing and shortness of breath. Children and certain racial groups, asthma and airpollution, especially African Americans and Native Americans, have experienced relatively greater increases in asthma prevalence.

Low income individuals also experience higher rates of asthma. Among children under age 18, This translates to approximately 4 million adults and 1. There are many asthma triggers in addition to air pollution. These include pollens, dust mites, animal dander, and fragrances, among others.

Typically an individual asthmatic responds to a unique subset of asthma triggers. Air pollution is a well-documented asthma trigger for some asthmatics; however, the role air pollution plays in initiating asthma is still under investigation and likely involves a complex set of interactions between indoor and outdoor environmental exposures and individual genetic susceptibility. There are a number of organizations that provide information on asthma management as well as conducting surveillance on asthma outcomes in California and nationwide.

Below lists a selection of these studies along with brief summaries of the study findings. Among many asthma and airpollution, the study found that children who participated in several outdoor sports and lived in communities with high ozone levels were more likely to develop asthma than similarly active children living in areas with less ozone pollution.

Also, children living near busy roads had an increased risk of asthma, and asthmatic children exposed to higher levels of air pollution were more likely to develop symptoms of bronchitis.

Living in areas of high air pollution has been shown to cause measurable lung damage in children aged 10 Risk of pediatric asthma morbidity from multipollutant exposures.

This study found that emergency department visits and hospital admissions for asthma increased in children who experienced higher levels of PM2. Hispanic and African American children, and those without private insurance tended to live in asthma and airpollution with higher levels of traffic-related air pollution. Is disparity in asthma among Californians due to higher pollutant exposures, greater susceptibility, or both?

The study found that some lower income and minority groups are more impacted by air pollution due to higher exposures than other groups. The study also found that certain lower income and minority groups are more vulnerable to the effects of air pollution exposures than other groups at the same levels of exposures, asthma and airpollution. Effect of GSTM1 genotype on ozone-induced allergic airway inflammation.

This study investigated the lung function and allergic responses to controlled ozone exposure in a group of allergic asthma and airpollution adults. The results indicate that exposure to ozone can intensify responses to inhaled allergen. Traffic-related air pollution and asthma in economically disadvantaged and high traffic compatability for cancer and capricorn neighborhoods in Los Angeles County, California, asthma and airpollution.

Higher levels of exposure to traffic air pollution increased the likelihood that a child had doctor-diagnosed asthma, asthma and airpollution, used asthma medication, asthma and airpollution, and had current wheeze, wheeze during the past year, orreduced measures of lung function.

Children living in lower socioeconomic status neighborhoods had greater risk than those in more affluent neighborhoods. Differences between the responses of girls and boys suggest that gender may influence susceptibility to air pollution.

This was a study of children living at varying distances from high-traffic roads in Alameda County, California, a highly asthma and airpollution region characterized by good regional air quality due to coastal breezes. The findings support the conclusion that even in an area with good regional air quality, proximity to traffic is associated with adverse respiratory health effects in children.

The results from this study suggest an association between exposure to NO 2 and both short and long-term reductions in lung function. Asthma and airpollution to traffic derived air pollution was also associated with reduced lung function. Lung function tended to be better in children that lived further from busy roads, indicating that exposure to traffic-related air pollution could negatively impact lung function.
