Health data An analysis that includes more than 500,000 children in health data may be considered as obese, one in four percent of obese children with obesity (23-27%).
This means that children who have been diagnosed with 10% of all children between 2 and 17 years of age, almost one million children in the U.S., have been prevented from maintaining healthy weight, researchers from Duke University, and Pediatric National Learning. Health System (PEDSnet). The discovery will announce the 26th edition of the magazine Paediatrics.
"Asthma is a chronic disease of children 1. In the case of children, some causes of genetic and viral infection can not be avoided," said Jason E. Lang, MD, associate professor of pediatrics in Duke and principal author of the research. "Obesity can be the only risk factor in childhood that can be susceptible to childhood, as it may be preventative, this is another proof that it is important to keep children's assets and healthy weight."
For retrospective research, researchers surveyed 507,496 children's data with more than 19 million doctoral visits in six child health centers.
The data was included in a clinical data network of PEDSnet between 2009 and 2015.
Those classified as amputees have been diagnosed in two or more medical appointments and have received prescription, such as an inhaler. The lung function tests also confirmed the illness.
Children classified as obesity – those with a body mass index of 95% of age and sex – have a greater risk of developing asthma than having a healthy weight of 30 percent. Asthma was less than obesity. Adolescent with overweight but not obese (IME 85-94 percent) 17% increase asthma risk compared to healthy weight.
Researchers calculate asthma risk using different models and have been adjusted according to the risk factors, such as sex, age, socioeconomic status and allergies. The results were similar.
The study has several limitations, Lang said, including data collected during the doctor's visit and not included in controlled clinical research. Lang said that more experiments are needed to overweight and obesity to demonstrate changes that cause asthma directly cause scientists to not fully understand why or why it happens.
Scientists have examined the hypothesis when they explain how developing children's lungs and ventilation develops as obesity due to obesity and inflammatory changes.
However, such findings and others, such as how much asthma improves weight loss, suggests that obesity is key or directly guilty, Lang said.
"I think it is reasonable that it is a relationship of cause," said Lang. "Being overweight or obese, develops an asthma that increases the risk of child development, and is a significant increase, paying close attention to the importance of preventing obesity."
