KIDS who are obese are 30 percent more likely to develop asthma, new research suggests.
Both f & # 39; one of the cases & # 39; ten asthma is caused by overweight, experts say – and the obesity crisis can & # 39; only make worse figures.
Ten of & # 39; astmatiċi children can prevent symptoms of respiratory conditions if they lost weight.
About one in four & # 39; British children are overweight or obese while one in 11 is asthmatic.
The primary author Dr. Jason Lang, associate professor of pediatrics at the University of & # 39; Duke, said: "Asthma is one chronic childhood disease and some causes such as genetics and viral infections during childhood are things that we can not prevent
"Obesity can & # 39; be the only factor & # 39; risk children asthma can & # 39; avoid.
"This is further proof that keeping children active and b & # 39; health is important."
Dr. Lang and his colleagues analyzed the medical records & # 39; & # 39 507 496 child; the United States more than 19 million visit & # 39; doctor.
Those classified as having asthma were diagnosed in & # 39; two or more doctoral appointments and also received a prescription for the condition, such as an inhaler.
Tests of their lung function also confirmed to have the disease.
Children classified as obese – those with & # 39; of body mass index (BMI) in the 95th percentile or higher for age and gender – were risk & # 39; 30 percent greater to develop -ażma than their peers b & # 39; & # 39 by weight; his health.
Children were classified as overweight – a BMI in the top 85th percentile – were 17 percent more likely to develop asthma.
It is not known exactly why the risk increases, but experts believe that children's lungs and airways can develop b & # 39; a different way when they are obese or overweight.
Obesity can & # 39; also raised inflammatory markers in the body, which has been linked to & # 39; asthma.

Asthma affects people of & # 39; all ages and often starts in childhood, but can & # 39; also appears for the first time in adults.
It is caused by the inflammation breathing tubes that carry air in and & # 39; outside the lungs.
This inflammation makes breathing tubes are very sensitive, so they become temporarily narrow.
It can & # 39; occur randomly, or after exposure to a trigger such as dust, pollen, smoke and even exercise.
The main symptoms include
- tight chest
Symptoms can sometimes create worse temporarily, this is known as an asthma attack.
M & # 39; there is no known cure for asthma but symptoms can be managed with & # 39; number & # 39; treatments.
The majority of treatments & # 39; asthma are taken using the & # 39; inhaler, spray or small appliances to deliver medicine & # 39; dust your breathing tubes while breathing.
The main treatments are:
- avoiding potential return
- inhalers suppressants – used inhalers when needed to quickly alleviate the symptoms of & # 39; asthma short
- preventive inhalers – inhalers used daily to reduce inflammation in the breathing tubes

Dr. Terri Finkel, the Children Nemours Hospital & # 39; Orlando, said: "The pediatric asthma is among the childhood conditions most prevalent and is & # 39; with high costs for patients, families and the larger health system.
"There are a couple & # 39; risk factors that can be avoided to reduce the incidence of & # 39; asthma, but our data shows that reducing early & # 39; obesity in childhood can & # 39; & # 39 b lower, significantly burden public health & # 39; asthma.
"The addressing childhood obesity should be a priority to help improve the quality of life of children and help reduce pediatric asthma.
"This is the first of its kind study, which looks at obesity and the risk of developing asthma completely f & # 39; pediatric population, and it is possible through the collaboration of PEDSnet data."
The main author Prof Lang added more experiments are needed to prove overweight and obesity cause changes directly lead to asthma because scientists do not fully understand how or why this occurs.

Dr Samantha Walker, director & # 39; research and policy – asthma UK, said: "Obesity is an obstacle to good health and this study shows that, as well as cause heart conditions and diabetes, can & # 39; cause asthma in children as well.
"asthma is a condition of & # 39; long life that affects an estimated & # 39; 1.1 million children in the EU United Kingdom, Flooded allow breathing and risk dying through asthma attack.
"Every child should have the opportunity for life b & # 39; robust free it asthma, Which is why it is vital to tackle obesity and children are encouraged to exercise.
"Children who already have asthma m & # 39; should be frightened to exercise because of their condition.
"Parents concerned about their children asthma health should ensure that their child take their medications as prescribed, follow written asthma plan & # 39; action and attend annual review with a GP or asthma nurse. "
