Objective: This study aims to analyze the relationship between employment status and the prevalence of chronic obstructive pulmonary disease (COPD) for manufacturing and construction workers.
Methods: Subjects, who had or have worked as temporary workers in manufacturing or construction worksites for the longest career years, were extracted from the KNHANES(2007-2009) database. Characteristics of demographical, socio-economic, and smoking history were treated as independent variables. Considering that smoking experience and age are significantly influential in the prevalence of COPD, logistic regressions were analyzed after stratifying subjects according to their smoking experience and age. A two-stage stratified systematic sampling method was applied for the logistic regression analysis.
Results: Age, gender, and household income level were associated with the prevalence of COPD in both smoking and non-smoking groups. However, employment status was only significant among smoking group. Smoking experience and age were significantly related to the prevalence of COPD among all age groups. In addition, employment status and household income level were also associated with the prevalence of COPD in young aged group. But gender was the only significant factor among the elder group.
Conclusions: This study confirmed that employment status was a major social factor which may be related to the prevalence of COPD. Proper supports such as providing safety measures should be provided to temporary workers to manage their respiratory health.
