Association between the telecommuting environment and somatic symptoms among teleworkers in Japan

Objectives: This study aimed to clarify the association between telecommuting environments and somatic symptoms among teleworkers in Japan. Methods: This cross-sectional study, conducted from September 27 to October 29, 2021, used data from the Japan COVID-19 and Society Internet Survey (JACSIS study) in Japan. Of the 31,000 male and female respondents, who were Japanese residents aged 15–79 years and were randomly selected from the panel members of an Internet survey company, 4,569 home-based teleworkers were finally included in the analysis; 26,431 respondents who met the exclusion criteria were excluded. The analysis included four cut-offs (≥4, 8, 12, and 16 points) for somatic symptoms on the somatic symptom scale-8 as objective variables, and the telecommuting environment, such as having adequate desk light and a quiet environment as explanatory variables. Adjusted Poisson regression analysis was conducted using demographic variables as covariates. Results: The prevalence ratio (PR) for somatic symptoms increased significantly as the number of poor telecommuting conditions increased, regardless of the cut-off value for somatic symptoms or the frequency of teleworking. In the telecommuting environment, the PR for somatic symptoms was significantly higher for the following six items: poor teleworking space to concentrate, inadequate foot space, poor communication environment, poor space for relaxation, noise, and inappropriate temperature and humidity. Conclusions: These results suggest that for home-based teleworkers, the more inadequate the telecommuting environment, especially in the aforementioned six areas, the higher the likelihood of somatic symptoms. Improving these environments may be useful in preventing various somatic symptoms.
