Exact epidemiological studies about the frequency of respiratory tract disease are difficult to perform. Vague definitions and inhomogeneous examination modalities render a comparison of results difficult. Some statements can be made. Chronic bronchitis occurs more often in males. The significance increases with advancing age. Smoking habits are of utmost importance. Indoor and outdoor air pollution is without doubt a significant agent in the etiology of chronic respiratory disease.
关于呼吸道疾病发病率的精确流行病学研究很难开展。定义模糊和检查方式不统一使得结果难以比较。不过仍能得出一些结论。慢性支气管炎在男性中更为常见。其重要性随年龄增长而增加。吸烟习惯至关重要。室内外空气污染无疑是慢性呼吸道疾病病因中的一个重要因素。
