PURPOSE
The aim of this study was to examine the effects of exposure to air pollution and cigarette smoke on respiratory function, respiratory symptoms, and the prevalence of COPD in individuals aged ≥50 years.
PATIENTS AND METHODS
We used spirometry and medical questionnaires to screen 433 individuals from Omuta City, Japan, an area with high levels of air pollution.
RESULTS
Non smokers had a high estimated COPD prevalence rate of 16%. Among smokers, the estimated prevalence of COPD was 29% in seniors (50- to 74-years group) and 37% in the elderly (>75 years group). We also found a correlation between levels of suspended particulate matter and COPD.
CONCLUSION
Both smoking and chronic exposure to air pollution (>5 years) decreased respiratory function, exacerbated respiratory symptoms, and increased the prevalence of COPD. We strongly recommend periodic screening for the elderly patients to facilitate early detection of respiratory disease.
目的
本研究旨在探讨空气污染和香烟烟雾暴露对≥50 岁人群的呼吸功能、呼吸症状和 COPD 患病率的影响。
患者与方法
我们使用肺活量计和医学问卷对日本大牟田市的 433 名成年人进行了筛查，该地区空气污染水平较高。
结果
不吸烟者 COPD 的预估患病率较高，为 16%。在吸烟者中，老年人（50-74 岁组）的 COPD 预估患病率为 29%，而老年人（>75 岁组）为 37%。我们还发现悬浮颗粒物水平与 COPD 之间存在相关性。
结论
吸烟和长期暴露于空气污染（>5 年）会降低呼吸功能，加重呼吸症状，并增加 COPD 的患病率。我们强烈建议对老年患者进行定期筛查，以便及早发现呼吸疾病。
