In the first phase of a two-phase cross-sectional survey conducted in Oslo from 1972 to 1974 a questionnaire was mailed to a random sample of 19998 persons aged 15 to 70 years. Information was received from 88.7% of those alive in the sample. The completion rate for each of 11 questions on respiratory symptoms in the mail questionaire varied between 94 and 98%. The crude prevalence rates of the symptoms cough in the morning, breathlessness climbing two flights of stairs and wheezing were 24%, 11% and 17%. Only 27% of the men and 46% of the women in the survey population were non-smokers. Among non-smokers, phlegm was reported more fequently by men, irrespectively of age, whereas breathlessness was reported more often by women than by men. In both sexes of non-smokers, a linear increase in prevalence of symptoms with age was observed for breathlessness, attacks of breathlessness, and coughing in the morning and during the day. The prevalence of respiratory symptoms was closely related to the amount smoked.
在1972年至1974年于奥斯陆开展的一项两阶段横断面调查的第一阶段，一份问卷被邮寄给了19998名年龄在15至70岁之间的随机抽样人员。从样本中在世的人员那里收到了88.7%的回复。邮寄问卷中关于呼吸道症状的11个问题，每个问题的完成率在94%至98%之间。早晨咳嗽、爬两层楼梯时气喘吁吁以及喘息这些症状的粗患病率分别为24%、11%和17%。调查人群中只有27%的男性和46%的女性不吸烟。在不吸烟者中，不论年龄，男性报告有痰的情况更频繁，而女性报告气喘吁吁的情况比男性更常见。在不吸烟的两性中，气喘吁吁、气喘发作以及早晨和白天咳嗽的症状患病率均随年龄呈线性增加。呼吸道症状的患病率与吸烟量密切相关。
