[Epidemiology of chronic cough in China: current status and future perspective].

Chronic cough is one of the most common major complaints in medical outpatient. Chronic cough not only seriously affects quality of personal life, but also burdens public health. Large-scale and high-quality epidemiological study on chronic cough has not been carried out in China, and relevant reviews are also lacking. Therefore, based on the studies concerning epidemiology of chronic cough in China, we reviewed the prevalence, risk factors, etiology, quality of life and economic burden. In addition, future perspectives and reasonable suggestions for the development of epidemiology of chronic cough were also proposed.慢性咳嗽是内科门诊最常见的主诉之一，不仅严重影响患者生活质量，还给社会造成了巨大的公共卫生资源负担。目前我国仍未开展大规模的、高质量的慢性咳嗽流行病学研究，相关综述也比较缺乏。本文结合国内已发表的慢性咳嗽流行病学有关文献，分别从患病率、危险因素、病因分布、生活质量状况、经济负担5个方面进行了综述，并对慢性咳嗽流行病学学科发展进行了展望及建议。.
