According to research in the United States, asthma can develop in overweight or obese children and teens.
Researchers say in the journal Pediatrics that research has long been linked between obesity and asthma in adults, but this provides conflicting evidence for this for young people.
In the current study, more than 500,000 children aged two to 17 years old participated on average for four years. As a result, 8% of these children had asthma.
The study showed that overweight children are 17% more likely to suffer from asthma than children with a healthy weight.
Obese young people are 26% more likely to develop asthma.
When researchers looked at the connection between asthma and obesity based on tests known as breath tests, it was clear how easy it was to get air out of the lungs.
The study showed that obesity is associated with an increased risk of developing asthma by 29 percent, based on this standard. “Experts believe that the abnormal lung growth associated with obesity blocks airflow,” said Jason Lang from Duke University School of Medicine, Northern California, lead author of the study.
He added that obesity can also cause the risk of so-called metabolic heart disease, such as high cholesterol, and the inability to use hormonal insulin to help get energy from blood sugar.
