Abstract

Objective: To investigate the association between job change-including first-time and repeat job changes-and new-onset physical and psychological symptoms in a general population sample in Japan.

Methods: We analyzed data from 19,281 Japanese adults who completed internet-based surveys in both 2022 and 2023. Job change within the past year was self-reported. Outcomes were new-onset symptoms in 2023, including headache, lethargy, and insomnia. Weighted logistic regression was used to estimate adjusted odds ratios (aORs) and 95% confidence intervals.

Results: Job changers (6.1%) were more likely to report new-onset headache (aOR, 1.57) and lethargy (aOR, 1.63). First-time job changers (2.0%) showed stronger associations, including insomnia (aOR, 2.93), and reported more adverse workplace conditions such as workload and harassment.

Conclusions: Job change, particularly for the first time, was associated with increased symptoms and unfavorable workplace conditions.

工作变化与自我报告症状：日本全国纵向研究

目的：调查日本普通人群中工作变化（包括首次和多次工作变化）与新发生理和心理症状之间的关系。方法：我们分析了19281名日本成年人的数据，这些成年人在2022年和2023年完成了基于互联网的调查。过去一年的工作变动是自我报告的。结果为2023年的新发症状，包括头痛、嗜睡和失眠。采用加权逻辑回归估计校正优势比（aORs）和95%置信区间。结果：换工作者（6.1%）更容易报告新发头痛（aOR, 1.57）和嗜睡（aOR, 1.63）。首次换工作的人（2.0%）表现出更强的相关性，包括失眠（aOR, 2.93），并报告了更多的不利工作环境，如工作量和骚扰。结论：换工作，特别是第一次换工作，与症状增加和工作环境不利有关。
