BackgroundThe proportion of Japanese workers experiencing intense worry or stress during working life is in excess of 60%, and the incidence of psychiatric disorders and suicide due to psychological burden from work duties is increasing. To confirm whether the stress response measured by the Brief Job Stress Questionnaire (BJSQ) can identify risk for depression, a cohort study was conducted to evaluate whether the stress response measured by BJSQ was associated with the onset of depression.MethodsA total of 1,810 participants aged 20–70 years in 2005 completed the stress response of the BJSQ and were followed-up until August, 2007 by examining sick pay records. Depression was defined by a description in sick pay records that included “depression” or “depressive symptoms” as a reason for sick leave according to a physician's medical certificate. The participants were divided into quartiles (Ql, Q2, Q3, and Q4) according to the total stress response score of BJSQ at baseline. Furthermore, the participants were divided into a higher score category (Q4) and a lower score category (Q1–Q3). Risk ratios of the stress response of the BJSQ for onset of depression were calculated using a multivariable Cox proportional hazard model.ResultsAmong 1,810 participants, 14 developed depression during a mean of 1.8 years of follow-up. The risk ratio was 2.96 (95% confidence interval [CI], 1.04–8.42, p for trend = 0.002) when the higher stress response score category of BJSQ was compared with the low stress response score category for sick leave due to depression. After adjusting for gender, age, marital status, and having children, the risk ratios were similar to no adjustment.ConclusionsThese findings suggest that the stress response measured by the BJSQ can demonstrate risk for the onset of depression.

The identification of risk factors for depression is necessary for the primary prevention of depression. The aim of this study is to determine whether self-efficacy (SE) is associated with onset of depression among workers. Medical expenditure records of 1,803 workers, who were clerks, system engineers, researchers, and service and sales workers in a software development company, were analyzed. Gender, age, job post, marital status, working hours, and SE were measured at baseline. Participants were divided according to quartiles of SE points. Risk ratios for undergoing a medical consultation due to depression were calculated using a multivariable Cox proportional hazards model. Of the 1,803 participants, 58 underwent medical consultation due to depression during a mean of 1.8 years of follow-up. Compared with the lowest quartile (Q1) of SE, adjusted hazard ratios (HR) were 0.65 (95%CI 0.34-1.25) for Q2, 0.49 (0.24-1.00) for Q3, and 0.40 (0.18-0.88) for Q4. In men, adjusted HRs were 0.87 (0.41-1.86) for Q2, 0.61 (0.26-1.41) for Q3, and 0.37 (0.14-0.98) for Q4. In women, no significant association was found. The present study suggests that low SE is a risk factor for onset of depression among male Japanese workers.

Aim To explore the experiences of Certified Nurses in Dementia Nursing (DCNs) concerning the effective education of staff in acute hospitals. Background In Japan, the number of inpatients with dementia who need medical care continues to increase. DCNs play an important role in educating medical staff about dementia care in acute hospitals. However, there is a lack of a clear understanding in this regard. Design A qualitative design using a thematic analysis. Methods Data were extracted from a focus group discussion conducted with 10 DCNs working in 10 different acute hospitals in central Japan. Participants answered semi‐structured, open‐ended questions about their experiences related to effective staff education. Categories, subcategories and themes were created. This study complied with the Standards for Reporting Qualitative Research. Results The two themes identified were “building a foundation for dementia care education” and “continuous support based on practical processes.”

Objectives: The objective of this study is to provide road centerline data for professionals of disaster medicine areas who are often beginners in GIS use. Methods: Newly developed vector tile format data were converted into shapefile format data, then were organized as second level medical districts to which medical professionals are accustomed. Results: Road centerline data in Japan is being prepared to release from Association for Promotion of Infrastructure Geospatial Information Distribution free of charge. Conclusion: Professionals of disaster medicine areas increased their accessibility of GIS. Logistic planning for evacuation activities and dispatching of rescue teams were improved.
