In 1990 and again in 1998 a study on the prevalence of contact allergy in the population was carried out by the Capital Region's Research Centre for Prevention and Health. These studies documented that contact allergy is of common occurrence.
A new study of the population began in 2006. The survey covered a representative sample of 3,600 residents over 18 years of age in 11 municipalities in the western part of Greater Copenhagen.
All were examined with patch tests and answered a questionnaire with background variables and specific questions aimed at allergy and eczema. Furthermore, all were tested for genes that predispose to sensitive skin.
These studies provide an opportunity to study the connection between individual susceptibility and environmental factors. Some results have already been reported including as a doctoral dissertation, but numerous studies are underway. Currently, the focus is on the correlation between nickel allergy and individual susceptibility due to lack of certain proteins (filaggrin) in the skin.
The activities will include an analysis of the link between exposure to various irritants for instance in consumer products and the risk of hand eczema.
In 2011 a new survey will begin. This time including questions on tattoos.
The studies are carried out in collaboration with the Research Center for Prevention and Health.
