Abstract

Objectives: Japan faces the need for occupational health management based on an understanding of workers' health and its impact on work productivity. With a paucity of comprehensive studies, we conducted this study to investigate work productivity by diseases among workers of various occupations in Japan, by using a large-scale database.

Methods: This retrospective, descriptive study utilized pre-existing data derived from health insurance claims and two surveys conducted in 2021. The analysis included the data of ≥19-year-old current workers with response data to the questions regarding Work Productivity and Activity Impairment (WPAI). The WPAI of the target diseases, defined by claims diagnosis codes, was plotted against the 1-year prevalence of each disease. The cost of lost productivity was estimated based on the response data regarding the WPAI.

Results: Overall, 31,540 individuals participated, and the analysis showed that psychiatric disorders, headache, epilepsy, and insomnia had a high percentage of participants reporting any level of WPAI, although the prevalence of these diseases was low. We also explored the cost of lost productivity to supplement the interpretation of the overall impact of health problems; however, no clear trend was observed.

Conclusions: Many Japanese workers with psychiatric disorders, headaches, epilepsy, and insomnia have impaired work productivity and daily activities.

工人诊断出的疾病对工作效率的影响：一项使用大规模索赔数据和日本工人调查数据的研究。

目标：日本需要在了解工人健康及其对工作生产力的影响的基础上进行职业健康管理。由于缺乏全面的研究，我们通过使用大型数据库进行了这项研究，以调查日本各种职业工人的工作效率与疾病的关系。方法：本回顾性描述性研究利用了来自健康保险索赔的已有数据和2021年进行的两次调查。分析包括≥19岁的在职工人的数据以及对工作效率和活动障碍（WPAI）问题的回答数据。根据索赔诊断代码定义的目标疾病的WPAI与每种疾病的1年患病率进行了对比。根据WPAI的响应数据估计了生产力损失的成本。结果：总共有31,540人参与了这项研究，分析表明，精神疾病、头痛、癫痫和失眠在报告WPAI水平的参与者中所占比例很高，尽管这些疾病的患病率很低。我们还探讨了生产力损失的成本，以补充对健康问题总体影响的解释；然而，没有观察到明显的趋势。结论：许多患有精神疾病、头痛、癫痫和失眠的日本工人的工作效率和日常活动受损。
