The impact of COPD severity on labor force participation and work loss is not well known. This study aimed to describe the characteristics of occupations and to evaluate the reason for work loss based on the severity of airflow obstruction (AO). We performed a cross-sectional study using data from the Korean National Health and Nutrition Examination Survey V-VI. We identified 9,901 people aged 40 to 60 years who had normal or AO in spirometry test results. AO was defined as a pre-bronchodilator forced expiratory volume in 1 second/forced vital capacity <70%. AO was present in 7.6% of the subjects, and 81.5%, 82.9%, and 71.6% of subjects with mild, moderate, and severe-to-very severe AO were in the labor force, respectively. Multivariable analyses revealed that severe-to-very severe AO subjects were more likely to have precarious job (adjusted OR = 4.71, 95% CI = 1.70-13.06) and cite health-related problem as the reason for not being in the labor force (adjusted OR = 3.38, 95% CI = 1.03-11.02). Overall, AO was not associated with any significant changes in labor force participation. However, subjects with severe-to-very severe disease were more likely to drop out of the labor force owing to their health-related problems.
COPD 严重程度对劳动力参与和工作损失的影响尚不清楚。本研究旨在描述职业特征，并根据气流阻塞（AO）的严重程度评估工作损失的原因。我们使用韩国国家健康和营养检查调查 V-VI 的数据进行了一项横断面研究。我们确定了 9901 名年龄在 40 至 60 岁之间、肺功能测试结果正常或 AO 的人。AO 定义为支气管扩张剂前用力呼气 1 秒/用力肺活量<70%。7.6%的受试者存在 AO，轻度、中度和重度至极重度 AO 受试者的劳动力参与率分别为 81.5%、82.9%和 71.6%。多变量分析显示，重度至极重度 AO 受试者更有可能从事不稳定工作（调整后的 OR=4.71，95%CI=1.70-13.06），并将健康相关问题列为未参与劳动力的原因（调整后的 OR=3.38，95%CI=1.03-11.02）。总体而言，AO 与劳动力参与率的任何显著变化均无关。然而，由于健康相关问题，严重至极重度疾病的患者更有可能退出劳动力市场。
