Main aim of cohort, please briefly describe the main objectives of the cohort
BAMSE stands for children, allergy, environment, Stockholm and epidemiology (the Swedish words barn, allergi, miljö, Stockholm and epidemiologi) and is a collaborative project between Karolinska Institutet and Region Stockholm. The original aim of the project was to study the impact of environmental factors for the development of allergic diseases.
