The prevalence of respiratory symptoms in 6,610 adults (3,372 men and 3,238 women); 35-36, 50-51 and 65-66 yrs of age, living in selected areas of Norrbotten, northern Sweden, were assessed in a postal survey. Response rates were identical in men and women, and at least one respiratory symptom was reported by 41% of each sex. Twenty two percent reported sputum production, and 14% reported wheezing. Despite differences in smoking habits and in the different age groups, the prevalence of symptoms did not differ between the sexes, or between urban and rural areas. Symptoms were as common in people living in the rural interior as in the industrialized coastal area. Present or past history of asthma was reported by 323 (5.9%) subjects, whilst 234 (4.1%) subjects stated that they had chronic bronchitis or emphysema. Less than half of the subjects who reported attacks of breathlessness together with wheezing stated that they had at any time had asthma. Whilst the exact prevalence of had asthma. Whilst the exact prevalence of at any time had asthma and chronic bronchitis cannot be assessed from this postal survey, its results indicate that the prevalence of asthma may be higher in northern Sweden than has been reported from the south of Sweden.
在瑞典北部诺尔伯特特定区域，对6610名成年人（3372名男性和3238名女性）进行了一项邮政调查，评估了他们在35 - 36岁、50 - 51岁和65 - 66岁年龄段的呼吸道症状患病率。男性和女性的回复率相同，每种性别中至少有41%的人报告了至少一种呼吸道症状。22%的人报告有咳痰，14%的人报告有喘息。尽管吸烟习惯和不同年龄组存在差异，但症状患病率在性别之间以及城乡地区之间并无差异。居住在农村内陆地区的人与工业化沿海地区的人症状同样常见。323名（5.9%）受试者报告有哮喘现病史或既往史，而234名（4.1%）受试者表示他们患有慢性支气管炎或肺气肿。在报告有呼吸急促发作并伴有喘息的受试者中，不到一半的人表示他们曾在任何时候患过哮喘。虽然无法从这项邮政调查中准确评估任何时候患哮喘和慢性支气管炎的患病率，但结果表明瑞典北部哮喘的患病率可能高于瑞典南部所报告的患病率。
