Statistical analysis of IgE antibodies to the common inhalant allergens in 44,496 sera.
A statistical analysis of RAST screening of 44,496 sera, submitted in 1986 and 1987 for routine diagnostic allergic examination, was performed. The sera were tested on a fixed panel of allergens, regardless of the patient's history. The association of a positive RAST with age and month of birth was studied. It was concluded that among the inhalant allergens, house-dust mite was the most frequent sensitizer for all age groups, followed by grass pollen and cat dander. Sensitization to cat dander occurred twice as often as sensitization to dog dander. Among children less than 4 years of age, a different profile of sensitization was found, indoor allergens (mites, animal danders) being more important than outdoor allergens (pollen). Furthermore, we found that children born during December-February had a slightly but significantly greater chance of becoming sensitized to grass pollen compared with children born during September and November (P less than .05). Children born during July-September had a greater chance of becoming sensitized to house dust mite compared with children born during January-March (P less than .05). Finally, it was found that children born during October-December had a greater chance of becoming sensitized to dog dander compared with children born during March-May.
