Health and Work Performance Consequences of Working From Home Environment: A Nationwide Prospective Cohort Study in Japan

Abstract

Objectives The physical work environment while working from home (WFH) is a key component of WFH, which, if inadequate, can impair workers' health and work functioning. We investigated environmental factors in WFH and worsening of work functioning. Methods A 1-year prospective cohort study was conducted involving 2530 Japanese workers who worked from home. Environment while WFH was assessed using binary subjective assessments based on existing guidelines. Existence of impaired work function was assessed using the Work Functioning Impairment Scale. We performed multilevel logistic regression analysis nested in the prefecture of residence. Results Lack of room/space for concentration, lack of enough light and foot space, inadequate temperature and humidity, and use of a sitting table were associated with work functioning impairment. Conclusions An inappropriate environment while WFH can have a negative impact on workers' health.
