Prevalence of atopy and pollinosis in the adult population of Switzerland (SAPALDIA study).
We present here prevalence data for atopy, pollinosis and atopic asthma obtained from a random sample of 8,357 adults (18-60 years) assessed by standardized computer-based interview as well as by allergy skin prick tests (SPTs) to grass, birch and Parietaria pollen, house dust mite, cat and dog epithelia and the moulds Alternaria and Cladosporium and by an in vitro allergy screen test.
On the basis of a positive Phadiatop (total 23.9% ; males 32.9%, females 25.0% ; p<0.001) and/or a positive SPT (total 23% ; males 25.0%, females 20.8% ; p<0.001), 32.3% of the study population were considered atopic (males 35.7%, females 28.8% ; p<0.001).
Concerning the prevalence of skin sensitization (SPT wheal=3 mm), the highest rate was observed for grass (12.7%), followed by house dust mite (8.9%), silver birch (7.9%), cat (3.8%) and dog (2.8%). The prevalence of atopic rhinitis was 13.5% and the prevalence ofcurrent hay fever varied between 9.1%, 11.2% (questionnaire answer and presence of atopy) to 14.2% (questionnaire answer only) with no significant difference by sex.
However, a significant difference for the prevalence rate of hay fever was observed between Swiss citizens with 11.6% and foreign citizens living in Switzerland with 8.7% (p<0.01).
Pollen-induced asthma (seasonal asthma symptoms and presence of a positive SPT to pollen) was judged to be present in at least 4.3%. These data confirm the high rate of atopy and atopic respirator.
