Fresher Air Linked to Drop in Asthmatic Children
A recent study from the University of Southern California has linked that the lessening of air pollution in southern California has greatly facilitated the respiratory health of the child demographic in the area.
An observational research method was spearheaded by Kiros Berhane, a professor of preventive medicine at the said university comprised their same subject study of 4602 children with an age range of 5 to 18, according to The New York Times.
The study setting which was overseen from the years 1993-2001, 1996-2004, and 2003-2012 years and involved 8 communities that belonged to the Southern California area. Fourth graders until they reached high school graduation within the entirety observed in the study.
To make a factual relationship between pollution levels and bronchitis, parents handed-out day to day updates on their children which included warning signs like coughs and presence of phlegm to concur with records registered on levels of ozone and nitrogen dioxide.
A case in point was that test subjects with asthma showed fewer indicators of the respiratory disease during reduction of air pollution. Nevertheless, the research as revealed by the university still has no direct premise on the improvement of the children's breathing, the majority of them believe that the results themselves can warrant the speculation.
"I think we can safely say this is one of the clearest pieces of scientific evidence to say reduction of air pollution can lead to improvement in respiratory health for children," Berhane pointed out while adding that this could be a springboard for a future policymaking.
This may be a light at the end of the tunnel for the state of California as most of its key cities which included Los Angeles, were ranked in 2014 to be the most polluted, according to CNN.
