Problems identified as associated with measuring the prevalence of asthma include the lack of an agreed definition, absence of standardization of questionnaires (both the content and the form in which questions are worded) the nonspecific nature of tests of bronchial responsiveness and the variation in the nature of asthma at different ages, seasonally and due to occupational exposures. Approaches to the resolution of these problems and outstanding questions are discussed.
已确定的与测量哮喘患病率相关的问题包括缺乏统一的定义、问卷缺乏标准化（包括内容和问题措辞形式）、支气管反应性测试的非特异性以及哮喘在不同年龄、季节和职业暴露情况下的性质差异。本文讨论了解决这些问题和未决问题的方法。
