Secondary objectives: - To study the onset and development of respiratory allergies and COBP in men and women from the general population, and to research associations with lifestyle and environmental factors, taking into account interactions between these factors and other personal and biological determinants. - To research associations with sensitisation to allergens (atopy), respiratory allergies, accelerated lung function decline and the development of COBP. - To investigate the natural history of allergic and non-allergic asthma (incidence, remission, severity) according to age and gender. - To evaluate the effects of obesity and importance of weight loss and physical activity on asthma severity and decline in lung function, as well as investigate the role of sex hormones and hormones linked to obesity such as leptin.null null United Kingdom Sweden Norway Germany Italy Spain France Belgium Congo Iceland Denmark Individuals General population Male Female Young Adult (19 to 24 years) Adult (25 to 44 years) Men and women from the general population between 20 and 44 years old in 1990-92 Clinical dataParticipant-reported health dataBiological data Health event/morbidity Health event/mortality Other Through organizations (health services or institutions schools businesses etc.) [1000-10000[ individuals Self-administered questionnaire Interview with the participant (including clinical) Observational Study Observational Study Cohort study 1173 Unknown Restricted access Data may be used by academic teams according to the steering committee's decision.
