Objective: Many companies in Japan have been increasingly interested in "health and productivity management (H&PM)." In terms of H&PM, we supposed that companies can enhance their employees' perceived workplace health support (PWHS) by providing support for workers' lively working and healthy living. This could then improve health-related QOL (HRQOL) by increasing PWHS. This study explored the relationship between PWHS and health-related quality of life (HRQOL). Methods: During the COVID-19 pandemic in December 2020, we conducted an Internet-based nationwide health survey of Japanese workers (CORoNaWork study). A database of 27,036 participants was created. The question regarding the intensity of PWHS was measured using a four-point Likert scale. We used a linear mixed model (LMM) to analyze the relationship between the intensity of PWHS and the four domains of CDC HRQOL-4 (self-rated health, number of poor physical health days, number of poor mental-health days, and activity limitation days during the past 30 days). Results: In the sex- and age-adjusted and multivariate models, the intensity of PWHS had a main effect on self-rated health and the three domains of unhealthy days (physical, mental, activity limitation). There was also a trend toward worse HRQOL scores as the PWHS decreased. Conclusions: This study aimed to document the relationship between PWHS and HRQOL. We found that the higher the PWHS of Japanese workers, the higher their self-rated health and the lower their unhealthy days. Companies need to assess workers' PWHS and HRQOL and promote H&PM. H&PM is also necessary to maintain and promote the health of workers during the COVID-19 pandemic.
