This study had the following specific objectives: a to describe the prevalence and severity of asthma, rhinitis and eczema among children living in various locations and to draw comparisons among countries and among locations within specific countries; b obtain baseline values in order to assess future tendencies in the prevalence and severity of these diseases; c provide a structure for further etiologic studies into genetics, lifestyle, medical care and environmental factors that may affect these diseases 1. The ISAAC was born out of two collaborative multinational studies of asthma in children, making it possible to standardize the written questionnaire WQ and video questionnaire VQ research instruments, both of which had been validated through pilot studies conducted in various countries, confirming their applicability and reproducibility 1.

International Study of Asthma and Allergies in Childhood (ISAAC): rationale and methods.

ISAAC, the International Study of Asthma and Allergies in Childhood , was formed in to facilitate research into asthma, allergic rhinitis and eczema by promoting a standardised methodology able to be used in diverse locations around the world. ISAAC developed from a merging of two multinational collaborative projects each investigating variations in childhood asthma at the population level. These were an initiative from Auckland, New Zealand to conduct an international comparative study of asthma severity, and an initiative from Bochum, Germany to conduct an international study to monitor time trends and determinants of the prevalence of asthma and allergies in children. ISAAC is a unique project investigating variations in the prevalence of these conditions at the population level and their potential causes. ISAAC has had three data collection phases.

 Сеньор, у нас нет рыжеволосых. У нас только настоящие андалузские красавицы. - Рыжие волосы, - повторил Беккер, понимая, как глупо выглядит. - Простите, у нас нет ни одной рыжеволосой, но если вы… - Ее зовут Капля Росы, - сказал Беккер, отлично сознавая, что это звучит совсем уж абсурдно.
