This review examines the challenges associated with occupational disease surveillance in Korea, particularly emphasizing the limitations of current data sources such as the Industrial Accident Compensation Insurance (IACI) statistics and special health examinations. The IACI system undercounts cases due to its emphasis on severe diseases and restrictions on approvals. Special health examinations, although they cover a broad workforce, are constrained by their annual scheduling, which leads to missed acute illnesses and subclinical conditions. The paper also explores the history of occupational disease surveillance in Korea, highlighting the fragmented and disease-specific approach of earlier systems. The authors introduce the newly established Korea Occupational Disease Surveillance Center (KODSC), a comprehensive nationwide system designed to gather, analyze, and interpret data on occupational diseases through a network of regional centers. By incorporating hospital-based surveillance and focusing on acute poisonings and other sentinel events, the KODSC aims to overcome the limitations of previous systems and promote collaboration with various agencies. Although it is still in the early stages of implementation, the KODSC demonstrates potential for improving data accuracy and contributing valuable insights for public health policy.

Occupational cancers arise from exposure to carcinogenic agents during work activities and represent a significant public health challenge. In Korea, compensation for occupational cancers has been available since 1964, with asbestos related mesothelioma recognized in 1993. Estimating the population attributable fraction (PAF) using national surveys and epidemiological studies is critical for assessing regulatory impact and forecasting future disease burden.Current Concepts: The International Agency for Research on Cancer categorizes carcinogens into distinct groups, and nearly 47 agents have been identified as relevant to occupational exposures. Advanced assessment tools, including job exposure matrices and the CAREX (CARcinogen EXposure) program, have been developed to accurately estimate exposure prevalence across industries. Comparative studies from Korea, the United Kingdom, France, Canada, Italy, and China indicate that the occupational cancer PAF ranges from approximately 1% to 8%. Notably, asbestos, welding fumes, diesel engineexhaust and emerging exposures such as night shift work are consistently recognized as major contributors to occupational cancer risk.Discussion and Conclusion: Although regulatory measures have successfully reduced exposure to several known carcinogens, long latency periods and evolving industrial practices continue to sustain the burden of occupational cancers. Incorporating detailed occupational histories in clinical assessments can facilitate early detection and targeted interventions. Ongoing refinement of exposure estimation methods and international collaboration remain essential for updating PAF calculations. Ultimately, proactive primary prevention and evidence-based regulatory policies are imperative to mitigate the impact of occupational carcinogens on cancer incidence and mortality. These findings underscore the urgency of continuous monitoring and targeted occupational health initiatives.

Background: The increasing rate of excess body weight (EBW) in the global population has led to growing health concerns, including cancer-related EBW. We aimed to estimate the population attributable fraction (PAF) of cancer incidence and deaths linked to EBW in Korean individuals from 2015 to 2030 and to compare its value with various body mass index cutoffs. Methods: Levin’s formula was used to calculate the PAF; the prevalence rates were computed using the Korean National Health and Nutrition Examination Survey data, while the relative risks of specific cancers related to EBW were estimated based on the results of Korean cohort studies. To account for the 15-year latency period when estimating the PAF in 2020, the prevalence rates from 2015 and attributable cases or deaths from 2020 were used. Results: The PAF attributed to EBW was similar for both cancer incidence and deaths using either the World Health Organization (WHO) Asian-Pacific region standard or a modified Asian standard, with the WHO standard yielding the lowest values. In the Korean population, the PAFs of EBW for cancer incidence were 2.96% in men and 3.61% in women, while those for cancer deaths were 0.67% in men and 3.06% in women in 2020. Additionally, PAFs showed a gradual increase in both sexes until 2030. Conclusion The EBW continues to have a significant impact on cancer incidence and deaths in Korea. Effective prevention strategies targeting the reduction of this modifiable risk factor can substantially decrease the cancer burden.

The Korean Atomic Bomb Survivor Cohort (K-ABC) study was designed to investigate the health impacts of atomic bomb exposure on Korean survivors and to explore whether these effects are passed down genetically to their descendants. This paper outlines the study’s design, data collection methods, baseline socio-demographic characteristics, exposure status, and disease prevalence among the participants, based on survey responses and health examinations. From 2020 to 2024, a total of 2,544 individuals, comprising 1,109 atomic bomb survivors (G1), 1,193 children of G1 (G2), and 242 grandchildren of G1 (G3), consented to participate in the study. Of these, 1,828 participants (659 in G1, 927 in G2, and 242 in G3) completed the survey and underwent health examinations, representing a participation rate of 71.9%. Exposure information was gathered using a questionnaire and verified through records from the Korean Red Cross and a handbook issued by the Japanese government. Disease prevalence was determined based on participants’ self-reported physician diagnoses. This study presents details about the K-ABC study and provides baseline data on the participants recruited. These data will be valuable for interpreting the results of future K-ABC studies.
