目的：慢性呼吸困难是数百万人的日常经历，尽管目前的治疗。本研究的目的是找出人们归因于他们的呼吸困难，而不考虑卫生服务的利用，并了解每个诊断组的人口统计学特征。一项面对面的、基于人口的调查（n = 4432）向修改后的医学研究理事会询问了居住在社区的南澳大利亚人（呼吸困难）量表（mMRC），以及如果他们呼吸困难是慢性的（过去6个月中至少3个月每天一次），呼吸困难的总持续时间以及他们将呼吸困难归因于什么身体系统。分类和连续变量进行了分析appropriately.Results：与63.7%的参与率，8.9%的受访者有一个mMRC得分>= 1。上气不接下气的人年纪更大（54.3岁SD 19.5，44.9岁SD 18.7; p < 0.001），最常将其慢性呼吸困难归因于肺部疾病（65%），如果呼吸困难是肺部疾病的结果，则经历慢性呼吸困难的时间明显更长（13.8年，SD 15.8）与其他原因（5.7年，SD 9.1; p < 0.001）相比。肺部疾病在患病率和持续时间方面的负担远远超过其他原因。这突出表明，需要加紧努力，尽量减少慢性肺病的原因，并更积极地减轻慢性呼吸困难的主观症状。
Objective: Chronic breathlessness is a daily experience for millions of people, despite current therapies. The objective of this study was to find out to what people attributed their breathlessness irrespective of health service utilization, and to understand the demographic characteristics in each diagnostic group.Methods: A face-to-face, population-based survey (n = 4432) asked community-dwelling South Australians the modified Medical Research Council (breathlessness) Scale (mMRC), and, if they were breathless was it chronic (daily for at least 3 of the last 6 months), total duration of this breathlessness and to what body system they attributed their breathlessness. Categorical and continuous variables were analyzed appropriately.Results: With a participation rate of 63.7%, 8.9% of respondents had an mMRC score >= 1. Breathless people were older (54.3 years SD 19.5, versus 44.9 years SD 18.7; p < 0.001), most often attributed their chronic breathlessness to lung disease (65%) and, if breathlessness was the result of lung disease, experienced chronic breathlessness for significantly longer periods of time (13.8 years, SD 15.8) compared with other attributed causes (5.7 years; SD 9.1; p < 0.001).Conclusion: Breathlessness is widely encountered. The burden in prevalence and duration generated by lung disease greatly surpasses other causes. This underlines the need to intensify efforts to minimize the causes of chronic lung disease, and to more actively palliate the subjective symptom of chronic breathlessness.
