NEW YORK (Reuters Health) – Children and adolescents who are overweight or obese may be more likely to have asthma, a US study showed. UU On Wednesday.

The researchers say in the journal Pediatrics, or pediatric medicine, that research has long been linked between obesity and asthma in adults, but provides contradictory evidence for young people.

The current study followed more than 500,000 children between the ages of two and 17 years to four years on average. The result was that approximately 8 percent of these children had asthma.

The study found that overweight children were 17% more likely to develop asthma than children with healthy weight, while those with obesity were 26% more likely to develop asthma.

When researchers looked at the association between asthma and obesity based on tests known as breath tests, which show how easily air is released from the lungs, they found that the correlation was stronger. The study concluded that obesity is associated with an increased risk of asthma by 29%, according to this more accurate diagnostic criteria.

"Experts believe that the abnormal growth of the lungs associated with obesity causes airflow obstruction," said Jason Lang, of the Duke University School of Medicine in Durham, Northern California, and lead author of the study.

He added that obesity can also cause the emergence of risk factors for the so-called metabolic heart disease, such as: high cholesterol and the inability to use the hormone insulin to help obtain energy from blood sugar, which can cause obstruction in the respiratory tract.

"Some studies have shown that asthma symptoms improve a lot with weight loss, but it is unknown how this happens," Lang said.

The researchers conclude that by assuming that there is no excess weight or obesity among children, 10% of asthma cases will be avoided.
