Asthma is one of the most common chronic disease in children. The affected individuals respond to certain causes such as allergens, infections or chemical stimuli with acute spasm and bronchial constriction. Cutting & # 39; & # can breathe resulting 39; be & # 39; threatening. But how would the suffering? Researchers now know that in addition to genetic predisposition, environmental factors also play a role – for example emissions of automotive exhaust, but also influences birth and child diet.
30 percent & # 39; higher risk
Another feature of & # 39; potential flu has now been discovered by Jason Lang of Duke University in & # 39; Durham and his colleagues: the body weight. For their study, researchers analyzed data from 507 496 boy and girl between the ages of & # 39; two and 17 years. The young patients together more than 19 million visits to the doctor between 2009 and 2015 – the results of & # 39; these appointments were introduced in & # 39; database for & # 39 purposes; research.
The evaluation showed that children with weight problems suffered by & # 39; significantly more frequently from asthma than children with & # 39; bw b & # 39; his health. Therefore, obese subjects had about 30 percent increased risk of disease. In overweight but not yet obese, the risk compared with normal weight was at least 17 percent higher. This relationship remained even after persistent team calculate other relevant factors such as age, gender or allergies.
Most cases can be avoided?
According to the researchers, it can & # 39; mean that obesity plays an essential role in the development of & # 39; asthma. It is true that, according to them, can & # 39; is ten percent of all asthma cases in the United States avoidable – which corresponds to about one million affected. "We can not do anything against several causes, such as genetic predisposition," says Lang. "Obesity and overweight are factors & # 39; risk can be avoided, which is further evidence of & # 39; how important style & # 39; an active lifestyle and weight b & # 39; his health in children. "
As highlighted by the authors & # 39; the study, their study is a controlled clinical trial. If indeed there is a causal relationship between obesity and asthma and what mechanisms causing injury to excessive pounds of lung health have yet to appear in & # 39; further studies. "But I think it appropriate to suspect a causal link here", says Lang. (Pediatrics, 2018)
