A study of the occurrence of asthma in six areas in four Nordic countries showed 18-25 percent of the populations investigated to have had wheezing or whistling in the airways during the previous 12-month period, and 2-3 percent to have had asthma attacks. The use of anti-asthmatics was found to have differed from one to another of the areas included in the study, and the result suggest the difference to depend upon corresponding differences in the extent to which an active approach to treatment was adopted for the care of patients with asthmatic problems.
一项针对北欧四个国家六个地区哮喘发病情况的研究表明，在接受调查的人群中，18%至25%的人在过去12个月内曾出现气道喘息或哮鸣，2%至3%的人曾发作哮喘。研究发现，所纳入各地区的哮喘药物使用情况存在差异，结果表明这种差异取决于对哮喘问题患者采取积极治疗方法的程度的相应差异。
