Research description

Since the late 80-th we have investigated the prevalence and time trends of allergic diseases in childhood, the natural course allergic diseases in childhood and risk factors of allergic diseases. The research has been clinically oriented with a focus on possibilities for implementation of preventive measures in the population.

The research originates from a birth cohort started in 1994, which includes more than 4000 children of Stockholm. The study was given the name BAMSE which is also a name for a Swedish cartoon figure loved by children. BAMSE is the abbreviation for Children/Barn, Allergy, Milieu, Stockholm, an Epidemiological survey. Repeated follow ups have been performed including investigations and objective measurements. So far the response rate has been excellent; 82% at the last 12 years of age follow up. Investigated areas so far include allergic heredity incl. genetic markers, early infections, early feeding and various aspects of air pollution. The importance of early exposure to inhalant allergens has been investigated as well as gender and socio-economy in relation to development of allergic diseasesl.

Another important area is has been to investigate the role of allergic sensitisation in relation to expression of allergic disease, with a specific focus on food allergens, particularly peanut and tree nut allergens. Partially this has been in collaboration with Sachs Children´s Hospital, Stockholm.

Collaboration is established with researchers within Centre for Allergy Research, KI; Stockholm University and researchers in Oslo, Helsinki, London, Berlin and Munich. Our research group is involved in 3 major EU-funded projects (GA2LEN, GABRIEL, ENRIECO). The research group contains amongst others physicians, nurses, BMA, database manager and statistician.
