Abstract

Background

Exposure to cooking fumes exposure likely increases the lung cancer risk in school cooks, but research on the incidence of lung cancer in school cooks is lacking. Therefore, this study aimed to examine a nationwide cohort of school cooks for lung cancer by linking three Korean social insurance databases to determine whether working as a school cook increases lung cancer risk.

Methods

A nationwide retrospective cohort of school cooks and clerks with lung cancer was established by linking Employment Insurance, Industrial Accident Compensation Insurance, and National Health Insurance Service databases. Covariates were matched using 1:1 propensity score matching (PSM) for school cooks and clerks. Age-standardized incidence and hazard ratios (HRs) for lung cancer were calculated using the Cox proportional hazards model. Fine–Gray subdistribution HRs were used for sensitivity analysis. After further categorization into never- and ever-smoked subcohorts, the same analyses were performed.

Results

Post PSM, we identified 76 cases of lung cancer in school cooks during 259,819 person-years of follow-up. The age-standardized incidence was 199.8 (95% confidence interval [CI]: 120.7–278.9) and 166.8 (95% CI: 95.8–237.7) for school cooks and clerks, respectively. The subdistribution HR for school cooks post PSM was 1.72 (95% CI: 1.14–2.60). In the never-smoked subcohort, the subdistribution HR for school cooks post PSM was 4.23 (95% CI: 2.36–7.58).

Conclusion

School cooks were at an elevated risk of developing lung cancer, likely due to exposure to cooking fumes, highlighting the need for improved ventilation and preventive measures in school kitchens to reduce lung cancer risk.
女性学校厨师患肺癌的风险:韩国全国回顾性队列研究
学校厨师暴露在烹饪烟雾中可能会增加患肺癌的风险,但缺乏对学校厨师肺癌发病率的研究。因此,本研究旨在通过连接三个韩国社会保险数据库来检查全国范围内的学校厨师肺癌队列,以确定作为学校厨师是否会增加肺癌风险。方法通过连接就业保险、工伤赔偿保险和国民健康保险数据库,建立全国范围内患肺癌的学校厨师和文员回顾性队列。用1:1的倾向得分匹配(PSM)对学校厨师和文员进行协变量匹配。使用Cox比例风险模型计算肺癌的年龄标准化发病率和风险比(hr)。采用细灰色亚分布hr进行敏感性分析。在进一步分为从不吸烟和曾经吸烟的亚队列后,进行了相同的分析。结果在259,819人-年的随访中,我们发现76例学校厨师肺癌。学校厨师和职员的年龄标准化发病率分别为199.8(95%可信区间[CI]: 120.7-278.9)和166.8 (95% CI: 95.8-237.7)。学校厨师PSM后的子分布HR为1.72 (95% CI: 1.14-2.60)。在从不吸烟的亚队列中,PSM后学校厨师的亚分布HR为4.23 (95% CI: 2.36-7.58)。结论:学校厨师患肺癌的风险较高,可能是由于暴露于烹饪烟雾中,这突出了改善学校厨房通风和预防措施以降低肺癌风险的必要性。

期刊介绍: Safety and Health at Work (SH@W) is an international, peer-reviewed, interdisciplinary journal published quarterly in English beginning in 2010. The journal is aimed at providing grounds for the exchange of ideas and data developed through research experience in the broad field of occupational health and safety. Articles may deal with scientific research to improve workers'' health and safety by eliminating occupational accidents and diseases, pursuing a better working life, and creating a safe and comfortable working environment. The journal focuses primarily on original articles across the whole scope of occupational health and safety, but also welcomes up-to-date review papers and short communications and commentaries on urgent issues and case studies on unique epidemiological survey, methods of accident investigation, and analysis. High priority will be given to articles on occupational epidemiology, medicine, hygiene, toxicology, nursing and health services, work safety, ergonomics, work organization, engineering of safety (mechanical, electrical, chemical, and construction), safety management and policy, and studies related to economic evaluation and its social policy and organizational aspects. Its abbreviated title is Saf Health Work.
