This study aimed to determine the risk of ischemic heart disease (IHD) and stroke among male couriers in Korea by linking the data from the National Health Insurance (NHI) and National Employee Insurance (NEI) databases.
As of 2015, the NHI and NEI databases were linked using individual IDs. A cohort of male couriers, aged between 20 and 64 years, ( = 5,012) was constructed using the Korean Employment Insurance Occupational Classification (KECO-2007). For comparison, a cohort of male total wage workers ( = 5,429,176) and a cohort of office workers ( = 632,848) within the same age group were also constructed. The follow-up was conducted until 31 December 2020 to confirm the occurrence of IHD and stroke. The diagnoses were defined using the 10th revision of the International Statistical Classification of Diseases and Related Health Problems (ICD-10) codes. The criteria included medical services for more than 1 day of hospitalization or more than 2 outpatient visits. The age-standardized incidence ratio (SIR) was calculated to evaluate the risk of occurrence. The hazard ratio (HR) was calculated using the Cox model after adjusting for age, alcohol consumption, smoking, obesity, income level, and employment duration as confounding variables.
The SIR of IHD for couriers was 1.54 (95% CI 1.31-1.78), while for office workers, it was 1.08 (95% CI 1.06-1.10), compared to male total wage workers. The SIR for stroke was higher for couriers at 1.84 (95% CI 1.40-2.28) and lower for office workers at 0.86, compared to male total wage workers. Couriers had a higher SIR for stroke at 1.84 (95% CI 1.40-2.28) and lower for office workers at 0.86 (0.83-0.89). Compared to total wage workers, couriers had a significantly higher adjusted HR for IHD at 1.60 (95% CI 1.37-1.87) and a higher HR for stroke at 1.39 (95% CI 1.07-1.79). Compared to office workers, couriers had a significantly higher HR for IHD at 1.34 (95% CI 1.13-1.59) as well as for for stroke at 1.43 (95% CI 1.08-1.88).
The incidence of IHD and stroke was higher among male couriers compared to male office workers and total wage workers, highlighting the need for implementing public health interventions to prevent IHD and stroke among couriers.
本研究旨在通过链接国民健康保险（NHI）和国民雇佣保险（NEI）数据库，确定韩国男性快递员患缺血性心脏病（IHD）和中风的风险。
截至 2015 年，使用个人 ID 对 NHI 和 NEI 数据库进行了链接。使用韩国就业保险职业分类（KECO-2007）构建了一个年龄在 20 至 64 岁之间的男性快递员队列（n=5012）。为了比较，还构建了一个男性全薪工人队列（n=5429176）和一个男性办公室工作人员队列（n=632848）。随访至 2020 年 12 月 31 日，以确认 IHD 和中风的发生情况。使用国际疾病分类第十版（ICD-10）代码定义诊断。标准包括住院超过 1 天或门诊就诊超过 2 次的医疗服务。使用年龄标准化发病率比（SIR）评估发病风险。使用 Cox 模型调整年龄、饮酒、吸烟、肥胖、收入水平和就业时间等混杂变量后，计算危险比（HR）。
与男性全薪工人相比，快递员的 IHD SIR 为 1.54（95%CI 1.31-1.78），而办公室工作人员的 SIR 为 1.08（95%CI 1.06-1.10）。与男性全薪工人相比，快递员的中风 SIR 更高，为 1.84（95%CI 1.40-2.28），办公室工作人员的中风 SIR 更低，为 0.86。与男性全薪工人相比，快递员的中风 SIR 更高，为 1.84（95%CI 1.40-2.28），办公室工作人员的中风 SIR 更低，为 0.86（0.83-0.89）。与全薪工人相比，快递员患 IHD 的调整后 HR 为 1.60（95%CI 1.37-1.87），患中风的 HR 为 1.39（95%CI 1.07-1.79），均显著更高。与办公室工作人员相比，快递员患 IHD 的 HR 为 1.34（95%CI 1.13-1.59）和中风的 HR 为 1.43（95%CI 1.08-1.88），均显著更高。
与男性办公室工作人员和全薪工人相比，男性快递员患 IHD 和中风的发病率更高，这表明需要实施公共卫生干预措施，以预防快递员患 IHD 和中风。
