This study from Danish general practice with the participation of 131 practices covering a population of 450,000 persons assesses all consultations concerning asthma during a 1-year period from June 1977. Asthma was defined as paroxysmal bouts of dyspnoea of an expiratory type. Results are presented from three groups of practices differing in their self-estimated rate of reporting. A total of seven to nine per 1000 of the population contacted a general practice during the study year (men: 7-10, women: 6-8). The prevalence may be described by a two-peaked curve with maxima at ages 5-14 years and 50-70 years. In the former group the prevalence rate among boys is double that of girls. In the later group asthma is more common among women until the age of 55, after that age it is more common among men. More than half of the patients consulted with symptoms during the study year. The isle of Fyn had a lower prevalence rate with and without symptoms that all other regions. The consultation rate was 5.7 per asthma patient per year. In about 25-30% of these consultations patients presented with symptoms. The isle of Fyn had the lowest consultation rate.
这项来自丹麦全科医疗的研究有131家诊所参与，覆盖45万人，评估了1977年6月起1年期间内所有有关哮喘的诊疗情况。哮喘被定义为呼气型阵发性呼吸困难。研究结果来自三组自我评估报告率不同的诊所。在研究年度，每1000人中共有7至9人前往全科医疗就诊（男性：7至10人，女性：6至8人）。患病率可用双峰曲线描述，在5至14岁和50至70岁出现峰值。在前一组中，男孩的患病率是女孩的两倍。在后一组中，55岁之前哮喘在女性中更常见，55岁之后在男性中更常见。超过一半的患者在研究年度因症状前来就诊。菲英岛无论有无症状，患病率都低于所有其他地区。哮喘患者的年诊疗率为每人每年5.7次。在这些诊疗中，约25%至30%的患者有症状。菲英岛的诊疗率最低。
