The Incidence of Atopy in a Working Population
Medical Officer, Unilever Merseyside Limited
Of 3407 United Kingdom industrial workers assessed for evidence of atopy at preplacement medical examination, 12.7 per cent were prick test positive to common allergens and reported experiencing atopic symptoms; 21.6 per cent were also prick test positive but were asymptomatic. Cat fur was the allergen most likely to produce positive results overall, but usually in the presence of another positive result, whereas grass pollens were cited as the cause of symptoms most often. The incidence of prick test positivity declined with age, and in each age group was higher in males. The use of cat fur for skin testing is more useful than that of aspergillus, which is often used. Suggestions are made concerning the application of the various factors involved in the concept of atopy when using this concept in preplacement medical examinations.
