Abstract

Introduction: Construction sites generate high levels of air pollution, contributing to more than 4% of particulate matter in the atmosphere. Literature indicates that on-site pollution is an important factor that contributes to lung impairments in construction workers. Chronic obstructive pulmonary disease (COPD) and acute respiratory distress syndrome (ADRS) are known to be exacerbated because of exposure to a variety of construction pollutants mainly particulate matter (PM10, PM2.5).

Methods: We conducted a systematic review and meta-analysis to assess whether exposure to construction site pollutants is associated with impairment of pulmonary parameters like Forced vital capacity (FVC), Forced expiration volume in 1 sec (FEV1) and FEV1/FVC. A total of 221 publications of observational studies were reviewed and 18 were selected; the data of which were meta-analyzed.

Results and discussion: In all studies the test subjects (construction workers) exposed to occupational air pollutants showed significantly lower FVC and FEV1 as compared expected levels (p≤ 0.01). The calculated Odds ratio indicates that there is positive association between COPD as compared to ARDS and exposure to pollutants.

建筑工人职业性空气污染物暴露与COPD高风险:一项荟萃分析研究
导言:建筑工地产生高水平的空气污染,占大气中颗粒物的4%以上。文献表明,现场污染是造成建筑工人肺部损伤的重要因素。已知慢性阻塞性肺疾病(COPD)和急性呼吸窘迫综合征(ADRS)因暴露于各种建筑污染物(主要是颗粒物(PM10, PM2.5))而加剧。方法:我们进行了系统回顾和荟萃分析,以评估暴露于建筑工地污染物是否与肺参数如强迫肺活量(FVC)、1秒强迫呼气量(FEV1)和FEV1/FVC受损有关。共审查了221篇观察性研究的出版物,并选择了18篇;数据进行meta分析。结果与讨论:在所有研究中,暴露于职业性空气污染物的测试对象(建筑工人)的FVC和FEV1明显低于预期水平(p≤0.01)。计算出的优势比表明,与ARDS相比,COPD与暴露于污染物之间存在正相关。
