Objectives-To assess the prevalence of atopy in a vocational school so as to evaluate the feasibility of pre-employment screening.
Methoss-The prevalence of atopy by family diathesis, prick tests, immunoglobulin E (IgE) concentrations, and personal history of allergic respiratory diseases was investigated in 144 trainee bakers and 81 students on a graphic artists course (mean age 15.4 years).
Skin sensitisation to wheat, rye, and barley flours, to a amylase, and to storage mites was also evaluated.
Personal allergic symptoms were reported by 13.2% of the bakers and 14.7% of the graphic artists and there was a significant association between symptoms and atopy by prick tests (odds ratio (OR) 17.2 ; 95% confidence interval (95% CI) 5.27-56.4) and by family history (OR 3.11 ; 95% CI 1.02-9.53).
When bakers were grouped according to the presence of allergic symptoms and results of immunological tests, 6.9% had asthma, 6.3% had rhinoconiunctivitis, and a high percentage (28.5%) were without symptoms but scored positive on prick tests or family symptoms.
Skin sensitisation to storage mites had similar prevalences (16%) in the two groups of trainees and occurred nearly always in atopic people.
Positive skin tests to wheat flour (3-5%), rye (0.7%), and a amylase (0.7%) were specific to bakers.
Conclusions-Pre-employment screening is a useful source of medical information and allows for counselling.
