无症状慢性阻塞性肺疾病患者相关特征分析

[目的]了解鄂南农村居民无症状慢性阻塞性肺疾病(COPD)患病状况及患者的流行病学特征,为防治COPD提供科学依据。[方法]以多阶段抽样方法,抽取鄂南农村居民1883例进行问诊、体检和肺功能检测,并采用统一的问卷进行调查。[结果]共检出COPD患者186例,总患病率为9.88%,其中无症状者71例,占38.17%;有症状者115例,占61.83%。无症状COPD的患病率为3.77%。无症状组和有症状组患者年龄、性别、职业、受教育程度、行饮情况,使用燃料情况和吸烟史比较,差异均无统计学意义(P﹥0.05)。两组吸烟指数差异有统计学意义(P﹤0.01),肺功能检测显示,有症状组第1s用力呼气容积(FEV1)、第1s用力呼气容积占预计值百分比(FEV1占预计值%)与无症状组比较,差异均有统计学意义(P﹤0.05或P﹤0.01)。[结论]该地区COPD患病率较高,其中无症状COPD的比例也较高。如果单凭症状,易造成COPD的漏诊和对疾病危害的低估。
