Children who are too heavy, obese higher risk of asthma

(Reuters Health) – Children and young people who are overweight or obese may be more likely to develop asthma, an U.S. study suggest.

Although obesity has been associated with asthma in adults for a long time, research so far has provided conflicting evidence as to whether this is also true for young people, and researchers point out in Pediatrics.

The current study followed more than 500,000 children, aged 2 to 17, for an average of four years. Overall, about eight per cent had been diagnosed with asthma.

When compared to children with healthy weight, children overweight were 17 percent more likely to have an asthma diagnosis and obese young people were 26 per cent more likely to be diagnosed with asthma, the study was discovered. This is based on the diagnosis or asthma drug but not on the results of breathing tests.

When researchers looked at the connection between asthma and obesity based on the so-called inspirational tests, which shows how easy people can breathe air out of their lungs, the link was stronger . Obesity was associated with a higher risk of 29 per cent of asthma based on these stronger diagnostic criteria, the study was discovered.

The study was a controlled experiment designed to prove that it could be overweight or obese directly causing asthma, but the results offer some of the most evidence motivating so far suggesting a connection really, says lead study author Dr. Jason Lang from Duke University School of Medicine in Durham, North Carolina.

"Experts have guessed that the unusual growth of lungs related to obesity causes an air flow barrier," said Lang by email.

Obesity can also trigger the development of cardiometabolic risk factors such as high cholesterol and inability to use hormone insulin to contribute blood sugar into energy that could lead to an impairment on the airway, Lang added.

"A number of studies have shown that asthma symptoms improve better with weight loss, but the exact mechanism is not anonymous," said Lang.

Someone from 23 per cent can attribute to 27 per cent of new asthma cases in obesity children directly to obesity, researchers are counted.

If children were not overweight or obese, they would avoid 10 percent of asthma cases, they are estimated.

A restriction of the study is that researchers rely on medical records kept by clinicians, and that asthma diagnosis documentation or the order of psychometry is a doctor's discretion, identifies the researchers.

It is also impossible to determine the pseudonymic study that could lead to obesity or may obesity lead to asthma.

However, the results suggest that asthma development can be prevented by helping children keep healthy weight, says Dr Deepa Rastogi, director of the Pediatric Asthma Center at the Montefiore Children's Hospital in Bronx, New York.

Even with asthma, children can help them to achieve and maintain a healthy weight, Rastogi said by e-mail.

"Children with asthma can be as active as they want to be – we have had Olympic level asthma athletes," said Rastogi, who wrote an editor who was published with the study.

"There is no activity that children with asthma need to avoid," added Rastogi. "They need to be aware of their symptoms and if they link a specific activity with asthma, they should take their asthma medication from the albuterol name 20 to 30 minutes before they take part in that activity."
