allergic rhinitisPHILADELPHIA, Nov. 15 (UPI) -- There is epidemiological evidence that the prevalence of allergic rhinitis is rising worldwide, according to U.S. researchers.

"Reports indicate (allergic rhinitis) has increased 100 percent in each of the last three decades in developed countries," said Dr. Eli O. Meltzer, co-director of the Allergy & Asthma Medical Group & Research Center and of the University of California in San Diego.

"With allergic disorders estimated to affect some 1.4 billion people globally, there appears to be a worldwide epidemic of allergic diseases. Studies suggest this is likely a consequence of our changing environment, reduced infections and genetic susceptibilities," said Meltzer.

Allergic rhinitis symptoms profoundly affect the quality of life as well as work productivity, according to Dr. Myron J. Zitt of the State University of New York at Stony Brook. "Adults may have mood swings and be less efficient at work or at home," he said. "They often have a poor quality of sleep, may suffer from obstructive sleep apnea and thereby experience daytime fatigue."

The data was presented at the annual meeting of the American College of Allergy, Asthma and Immunology in Philadelphia.
