Study shows a strong correlation between childhood obesity and asthma
Ten percent of pediatric asthma cases could be avoided if childhood obesity were eliminated. This is the conclusion of a research led by Nemours Children’s Health System.
The research, published in Pediatrics, the journal of the American Academy of Pediatrics, reported on the analysis of medical records of more than 500,000 children. The study is among the first to use the resources of PEDSnet, a multi-specialty network that conducts observational research and clinical trials across eight of the nation’s largest children’s health systems.
PEDSnet is funded by the Patient-Centered Outcomes Research Institute (PCORI), a government-supported nonprofit.
Between 23 to 27 percent of new asthma cases in children with obesity are directly attributable to obesity
Pediatric asthma is among the most prevalent childhood conditions and comes at a high cost to patients, families and the greater health system. There are few preventable risk factors to reduce the incidence of asthma, but our data show that reducing the onset of childhood obesity could significantly lower the public health burden of asthma,” said Terri Finkel, MD, PhD, Chief Scientific Officer at Nemours Children’s Hospital in Orlando and one of three Nemours researchers participating in the study. “Addressing childhood obesity should be a priority to help improve the quality of life of children and help reduce pediatric asthma.”
In their analysis, the researchers found that the incidence of an asthma diagnosis among children with obesity was significantly higher than in children in a normal weight range. Between 23 to 27 percent of new asthma cases in children with obesity are directly attributable to obesity. Additionally, obesity among children with asthma appears to increase disease severity.
Being overweight was identified as a modest risk factor for asthma, and the association was diminished when the most stringent definition of asthma was used.
