Project description

South Karelian Allergy Research Project focuses on quantifying the occurrence of allergies and their risk factors in general child population. In 2005-6, the questionnaire survey with complementary interviews for parents was carried out in all child health clinics of South Karelian area. In addition, results of allergy tests performed for children were retrospectively collected from patient records. The target population included all children living in the area and born between April 1, 2001 and March 31, 2006. The parents of almost 4000 children returned the questionnaire.
