표준화된 역학조사를 수행하기 위하여 현재까지의 산업안연보건연구원에서 수행된 직업성천식 역학조사의 변천사를 파악하고, 기존 역학조사 보고서를 고찰하여 직업성천식의 업무관련성 평가기준을 작성하고자 하였다. 업무관련성 평가를 위해 근로복지공단 등에서 직업성 천식으로 분류되어 검토 의뢰되어 수행된 산업안전보건연구원 역학조사 보고서 90건 중 최종진단이 천식으로 확인된 환례는 81건이었으며, 이중 직업성 천식이 64건, 직업악화성천식이 4건, 그리고 비직업성천식이 13건이었다. 사망환례 7건을 제외한 생존환례 74건을 고찰한 결과 의뢰기관의 역학조사 요청이 부적절한 경우(예: 천식의 직업종사 후 진단과 인정기준이 있는 물질의 노출이 확인된 경우)가 6건(8.1%)이었으며, 역학조사과정 또는 의뢰당시에 객관적 검사방법에 의해 천식을 진단(비특이 또는 특이 흡입유발 검사, 기관지 확장제 투여후 기관지 확장반응, 최대호기 유속 변화)한 환례가 70건(94.6%), 한 가지 이상의 객관적 검사방법에 의해 작업관련성을 확인(노출물질의 특이 유발검사, 작업중 FEV1, PEFR의 변화, 작업관련 연속적 비특이 유발검사의 변화)한 환례는 42건(65.5%)이었다. 직업성 천식 64건 중 디이소시아네이트가 원인물질인 환례가 32건(50%)로 가장 많았고, 의뢰 된 환례 중 알려진 천식유발 물질에 의한 천식의 빈도는 최근 들어 감소 추세를 보였다. 이 작업을 통해 직업성천식의 업무관련성 평가에 필수적인 지침, 부가적인 지침, 기타 확보해야 할 변수를 중심으로 가이드라인을 제시하고자 하였다.

Background: The prevalence of anxiety disorders has been increasing in South Korea, with recent studies reporting anxiety disorders as the most common mental disorder among all South Korean females. Anxiety disorders, which are independent risk factors of suicidal ideation and suicide attempts, are significantly correlated with productivity loss, high medical costs, impaired work performance, and frequent worker absence, and thus are potentially serious problems affecting the health of South Korean female workers. In previous studies, anxiety disorders were shown to have a significant correlation with occupational stress. This study seeks to examine the prevalence of anxiety symptoms as well as the relationship between occupational stress and anxiety symptoms among South Korean female manufacturing workers. Methods: A structured self-reported questionnaire was administered to 1,141 female workers at an electrical appliance manufacturing plant. The questionnaire collected data on general characteristics, health behaviors, sleep quality, job characteristics (shift work, shift work schedule, and job tenure), occupational stress, and anxiety symptoms. Sleep quality was measured using the Pittsburgh Sleep Quality Index, occupational stress with the Korean Occupational Stress Scale-Short Form (KOSS-SF), and anxiety symptoms with the Korean version of the Beck Anxiety Inventory. A chi square test was conducted to determine the distribution differences in anxiety symptoms based on general characteristics, health behaviors, job characteristics, and sleep quality. A linear-by-linear association test was used to determine the distribution differences between anxietysymptoms and the levels of occupational stress. Last, logistic regression analysis was used in order to determine the association between occupational stress and anxiety symptoms. Results: The prevalence of anxiety symptoms was 15.2 %. In the multivariate logistic regression analysis that adjusted for sleep quality and general characteristics, a significantassociation was found for those with anxiety disorders; the odds ratios (OR) were significantly higher the greater the total KOSS-SF score (moderate-risk group OR=2.85, 95 % CI=1.79–4.56; high-risk group OR=5.34, 95 % CI=3.59–7.96). In addition, excluding insufficient job control, all other KOSS-SF subscales were significantly associated with anxiety symptoms, and a relatively high OR was seen in the high-risk group for job demand (OR=3.19, 95 % CI=2.27–4.49), job insecurity (OR=4.52, 95 % CI=2.86–7.13), and occupational culture (OR=4.52, 95 % CI=2.90–7.04). Conclusion: There was a significant association between anxiety symptoms and occupational stress stemming from the psychosocial work environment among these South Korean female manufacturing workers. Future longitudinal studies are needed to examine the association between the occupational stress caused by the psychosocial work environment and the incidence of anxiety disorders and anxiety symptoms. Furthermore, intervention programs that aim to address the prevalence of anxiety symptoms and improve the psychosocial work environment, especially for younger female manufacturing workers, are needed.
