Study: Allergy Risks Are Elevated In Children Born In America
ATLANTA (CBS Atlanta) - New research indicates that children born in the United States are more likely to develop allergy-based diseases such as asthma than kids born abroad.
CBS News is reporting that researchers at St. Luke’s-Roosevelt Hospital Center in New York City noticed the trend while examining data collected by the National Survey on Children’s Health.
“Foreign-born Americans have significantly lower risk of allergic disease than U.S.-born Americans,” authors of the new study were quoted as saying. “However, foreign-born Americans develop increased risk for allergic disease with prolonged residence in the United States.”
The survey from which researchers drew their conclusions represented over 91,600 children, from newborns to those who are 16 years of age. All of them had been studied since 2007 or 2008, CBS News found.
Of those, a reported 34.5 percent of kids born in America had an allergic disease, as compared to just 20.3 percent born outside of the United States also diagnosed with an allergy-related disorder.
Additionally, children born outside of the United States but living here longer than 10 years showed a greater risk of developing diseases such as eczema and hay fever, though were said to be more immune to onsets of asthma and food allergies than their American-born counterparts.
“The results of the study suggest that there are environmental factors in the U.S. that trigger allergic disease,” study author Dr. Jonathan Silverberg of St.Luke’s-Roosevelt and the Beth Israel Medical Center was quoted as telling Reuters.
He added, “Children born outside the U.S. are likely not exposed to these factors early in life and are therefore less likely to develop allergic diseases.”
The study was published in JAMA Pediatrics late last month, CBS News learned.
According to the Centers for Disease Control and Prevention in Atlanta, allergies presently affect millions of Americans of all ages.
“[Those affected] suffer from allergies caused by everyday exposures to agents such as dust mites, cat dander, and pollens,” the CDC noted on its official website. “Agents encountered by workers can also cause allergic problems such as asthma, nasal and sinus allergies, hives, and even severe anaphylactic reactions.”
