title: Epidemiologic approaches for the identification of asthma.
abstract: Clinical, physiologic, and questionnaire approaches can be used to identify subjects with asthma in an epidemiologic investigation. Each method, however, may select differing subsets of the population. At present, a comprehensive asthma questionnaire is unavailable; the difficulty of defining asthma in operational terms has been a major obstacle in the development of such a questionnaire. This review describes the questionnaires prepared by the British Medical Research Council and the American Thoracic Society and suggests modifications.
