33% of new cases of childhood asthma in Europe caused by air pollution

Another piece of research, this time conducted by a Spanish institute, confirms that among the main factors of asthma for children is air pollution.

According to the new study, published in the European Respiratory Journal and conducted by the Institute for Global Health in Barcelona (ISGlobal), 33% of new annual cases (over 190,000 cases) of childhood asthma could be avoided if European countries “were able to reduce air pollution levels to the lowest levels recorded in the literature.”

This means that air pollution is basically the basis of one-third of children’s asthma cases. According to the study, up to 11% of new cases (over 66,000 cases) of childhood asthma could also be avoided every year if European countries “respected the WHO guidelines on air quality of PM 2.5.” The latter is a classification that indicates that fine particulate matter, essentially the powders, whose grains are fine to this point (at least 2.5 ┬Ám, or a quarter of a 100th of a millimeter) to be able to penetrate into the human lungs.

Researchers analyzed data from 18 European countries while data on exposure to air pollutants were obtained through a statistical model based on multiple measurements performed in Europe.
