据预测,到2020年,慢性阻塞性肺疾病(COPD)将成为全球第三大死亡和残疾原因。在对14个年龄在40岁及以上的人群进行的调查中,使用高质量肺量测定法估计了由正常下限定义的COPD患病率。使用随机效应荟萃分析评估关联的强度和一致性。在每个研究中心,吸烟包年与COPD风险相关。在调整了这一影响后,我们仍然观察到COPD风险与年龄的显著相关性比值比(OR):1.52/10年(95%CI:1.35,1.71),体重指数(肥胖与正常体重相比的OR:0.50(95%CI:0.37,0.67)),教育水平(OR:0.76/完成教育阶段(95%CI:0.67,0.87)),10岁前因呼吸问题住院(OR:2.35(95%CI:1.42,3.91)),被动吸烟暴露(OR:1.24(95%CI:1.05,1.47))、肺结核(OR:1.78(95%CI:1.17,2.72))和COPD家族史(OR:1.50(95%CI:1.159,1.90))。虽然吸烟是COPD最重要的危险因素,但其他危险因素也很重要。需要更多的研究来阐明低收入和中等收入国家的相关风险因素,这些国家将发生COPD的最大影响。
Chronic obstructive pulmonary disease (COPD) is predicted to become the third commonest cause of death and disability worldwide by 2020. The prevalence of COPD defined by the lower limit of normal was estimated using high quality spirometry in surveys of 14 populations aged 40 years and over. The strength and consistency of associations were assessed using random effects meta-analysis. Pack-years of smoking were associated with risk of COPD at each site. After adjusting for this effect, we still observed significant associations of COPD risk with age (Odds Ratio (OR): 1.52/10 years (95%CI: 1.35,1.71), body mass index (OR: 0.50 in obese compared with normal weight (95%CI: 0.37, 0.67)), level of education (OR: 0.76/stage of education completed (95%CI: 0.67, 0.87)), hospitalisation with a respiratory problem before age 10 years (OR: 2.35 (95%CI: 1.42, 3.91)), passive cigarette smoke exposure (OR: 1.24 (95%CI: 1.05, 1.47)), tuberculosis (OR: 1.78 (95%CI: 1.17, 2.72)), and a family history of COPD (OR: 1.50 (95%CI: 1.159, 1.90)). Although smoking is the most important risk factor for COPD, other risk factors are also important. More research is required to elucidate relevant risk factors in low and middle-income countries where the greatest impact of COPD will occur.
