As the smoking ban in public places affects children with asthma

smoking banThe new study focuses on the urgent issue of whether the smoking ban has helped improve the health of people in public places. Studies show that the number of children attending the emergency department with complaints of asthma, decreased by 17 percent.

"In the 20 urban areas where a ban during the 2000s, fewer children were sent to the emergency department with an exacerbation of asthma, - says senior study author Teresa Shayerman, a professor at Brown University School of Public Health -. Clean Air Act reduced the expensive health care in the rooms and helped parents and children to avoid stressful situations. "

Shayerman and other researchers from the University of Chicago and the University of Kansas say that all cities have to accept the limitations that do not allow smoking in enclosed public places such as restaurants.

"Children can not control the environment, - says one expert -. Research shows that even a brief exposure to the public of passive smoking has an effect on asthma."

In a study published in the Annals of Allergy, Asthma & Immunology, studied the cases of exacerbation of asthma in 20 children's hospitals in 14 states, Washington, DC. In each hospital, the researchers counted the number of visits during the three years before and after the ban on smoking on the premises.

In total, they counted 335.588 visits from 2000 to 2014. This excludes such factors as the patient's sex, age and race. 

In each area, the number varied showing a decrease or, conversely, increase. The total for all 20 visits to hospitals decreased after the ban came into force: 8 percent in one year since the adoption, 13 percent after two years and 17 percent after three years.

To see the long-term measurements, which had nothing to do with the smoking policy, the researchers conducted a test where an arbitrarily determined date of January 1, 2007 as a point of reference for each hospital. This test did not show a decrease in the number of visits, which means that there is no reduction of national emergency asthma.

Scientists recognize that the study only shows the connection and does not prove that the bans have led to a reduction in emergency room visits. It was recognized that secondhand smoke is a trigger for asthma.

"In conjunction with other research results make it clear that legislation on clean indoor air improves the health of the population", - says Shayerman.
