Abstract
OBJECTIVES
In recent years, occupational injuries have sparked a huge social and political debate. Thus, in this study, we focused on the characteristics and trends of occupational injuries requiring hospitalization in Korea.
METHODS The Korea National Hospital Discharge In-depth Injury Survey was designed to estimate the annual number and characteristics of all injury-related hospitalizations in Korea. The annual number of hospitalizations due to occupational injuries and the age-standardized rates (ASRs) were estimated from 2006 to 2019. The annual percentage change (APC) and average annual percentage change (AAPC) of ASRs and their 95% confidence intervals (CIs) were calculated using joinpoint regression. All analyses were stratified by gender.
RESULTS In men, the APC of the ASRs of all-cause occupational injuries was -3.1% (95% CI, -4.5 to -1.7) in 2006-2015. However, a non-significant upward trend was observed after 2015 (APC, 3.3%; 95% CI, -1.6 to 8.5). In women, the APC of all-cause occupational injuries was -8.6% (95% CI, -12.1 to -5.1) in 2006-2012. However, a non-significant upward trend was observed after 2012 (APC, 2.1%; 95% CI, -0.9 to 5.2). A recent upward trend in stabbing injuries was observed after 2012 (APC, 4.7%; 95% CI, -1.8 to 11.8) in women. A non-significant overall increasing trend was also observed for occupational injuries caused by exposure to extreme temperatures (AAPC, 3.7%; 95% CI, -1.1 to 8.7) in women.
CONCLUSIONS A recent upward trend in all-cause injury hospitalizations and hospitalizations caused by stabbing injuries was observed. Therefore, active policy interventions are required to prevent occupational injuries.

본 연구는 퇴원환자 심층조사를 사용하여 2006년부터 2019년까지 우리나라에서 발생한 업무상 손상의 추세를 연령표준화발생률을 구함으로써 분석하였다. 남녀 모두에서 2010년대 초반 까지는 발생률이 유의하게 감소하는 추세를 보였지만, 2013-2015년 이후부터는 통계적으로 유의하지 않은 점진적 상승 추세가 관찰되었다. 이러한 연구 결과는 업무상 손상을 예방하기 위해 적극적인 정책적 개입이 필요하다는 것을 시사한다.
Key Message
This study analyzed the trends in work-related injury occurrences in South Korea from 2006 to 2019 based on a nationally representative, repeated cross-sectional dataset. Age-standardized rates were calculated and their annual trend was estimated using a JointPoint regression. While both males and females exhibited a significant decline in occupational injury rates until the early 2010s, a non-significant but gradual upward trend has been observed since 2013-2015. These findings underscore the need for active policy interventions to prevent work.

Abstract
OBJECTIVES
Construction workers face an elevated risk for several types of cancer. Nevertheless, there is a lack of large-scale epidemiological studies examining the risk of all cancers in construction workers. This study aimed to investigate the risk of various cancers in male construction workers using the Korean National Health Insurance Service (NHIS) database.
METHODS We used data from the NHIS database from 2009 to 2015. Construction workers were identified using the Korean Standard Industrial Classification code. We calculated the age-standardized incidence ratios (SIRs) and 95% confidence intervals (CIs) for cancer occurrence in male construction workers compared to all male workers.
RESULTS Compared to all male workers, the SIRs for esophageal cancer (SIR, 1.24; 95% CI, 1.07 to 1.42) and malignant neoplasms of the liver and intrahepatic bile ducts (SIR, 1.18; 95% CI, 1.13 to 1.24) were significantly higher in male construction workers. The SIRs for malignant neoplasms of the urinary tract (SIR, 1.19; 95% CI, 1.05 to 1.35) and non-Hodgkin lymphoma (SIR, 1.21; 95% CI, 1.02 to 1.43) were significantly elevated in building construction workers. The SIR for malignant neoplasms of the trachea, bronchus, and lung (SIR, 1.16; 95% CI, 1.03 to 1.29) was significantly higher in heavy and civil engineering workers.
CONCLUSIONS Male construction workers have an increased risk for esophageal cancer, liver cancer, lung cancer, and non-Hodgkin’s cancer. Our results indicate that tailored strategies for cancer prevention should be developed for construction workers.

건설 노동자는 작업환경에서 수많은 유해 인자에 노출되지만, 건설 노동자에서 암의 연령 표준화 발생비를 조사한 역학 연구는 부족하다. 이번 연구에서 식도암과 간담도암의 연령 표준화 발생비는 전체 남성 근로자에 비해 남성 건설 근로자에게서 증가하였다. 이러한 결과는 건설 근로자에서 암 위험이 증가했음을 나타내며, 이 직업군에서 암 예방을 위한 추가 연구와 정책이 필요함을 의미한다.
Key Message
Despite the exposure of construction workers to numerous hazardous substances at workplace, epidemiological studies investigating the risk of all cancers in this occupational group are lacking. In this study, the age-standardized incidence ratio of esophageal cancer and hepatobiliary cancers increased in male construction workers compared to all male workers. Our results underscore the increased several cancer risks faced by male construction workers, necessitating the development of tailored strategies for cancer prevention in this occupational group.
