The aim of this study was to look into the prevalence of depressive symptoms and the factors that affect them in Japan. Depressive disorder is one of the most common mental illnesses in Japan, and it is a major public health problem. The data was analysed to see whether there was a connection between high CES-D scores, socioeconomic status, and employment-related variables.
Employees in Akita prefecture completed the Center for Epidemiologic Studies Depression Scale (CES-D) between November and December 2010 as part of a study. The CES-D scores had to be at least 16 to be considered (high scorers).
Being female, young age, less hours of sleep on weekdays, and working over 8 hours a day were socio-demographic and occupation-related factors associated with a high risk of depression, while drinking alcohol one to two days per week, but only in men, was significantly associated with a low risk of depression. The current findings were consistent with those of a previous study conducted in 2007. However, the current findings on work categories and smoking habits were not substantially correlated with depression, and thus differed from those of the 2007 survey.
Conclusions: The information provided in this paper will aid in identifying workers that are at high risk of developing depressive disorders, as well as identifying the socio-demographic and work-related factors that contribute to this risk. These findings can be used as CES-D benchmark values and can aid in the prediction of depressive disorders.
