Health Management of Workers with Presenteeism is a New Challenge in Occupational Health.

There has been a growing interest in presenteeism in recent years in both the occupational health and management fields. However, the term "presenteeism" was introduced in Japan relatively recently, and only limited knowledge on the subject has since been accumulated. This review will outline the current knowledge on presenteeism and discuss the significance of addressing presenteeism in occupational health in Japan. A common definition of presenteeism is the state that showing up at the office while having health problems, and some have added a decline in productivity. Several methods have been proposed to convert a degree of presenteeism into monetary value in terms of a health economics perspective, but there is no consistent method. A new approach is needed to evaluate and support workers who are experiencing presenteeism.
