Associations of occupation, employment type and company size with actions related to health examinations among Japanese employees.
Authors: Seko R, Kawado M, Saito S, Shibuya T, Miyamoto M, Yamada H, Taniwaki H, Hashimoto S Abstract Taking action in response to health examination results is important to stay healthy. We aimed to investigate the associations between occupation, employment type and company size, and having a health examination and taking action in response to the results among Japanese employees. We focused on three particular actions by employees in response to health examination results: paying attention to one's health, receiving health guidance, and visiting a medical institution. We used anonymous data from the 2010 Compreh...

Biological monitoring of occupational ethylbenzene exposure by means of urinalysis for un-metabolized ethylbenzene.
This study aimed to examine quantitative relation between ethylbenzene (EB) in air (EB-A) and un-metabolized EB in urine (EB-U) for biological monitoring of occupational EB exposure by urinalysis for EB. In total, 49 men in furniture production factories participated in the study. Time-weighted average EB-A was monitored by diffusive sampling. Urinalysis for EB was conducted by head-space gas-chromatography with end-of-shift samples. Data were subjected to regression analysis for statistical evaluation. A geometric mean (GM) and the maximum (Max) EB-A levels were 2.1 and 45.5 ppm, respectively. GM and Max for EB-U (observe...

Relationship between treatment and period of absence among employees on sick leave due to mental disease.
This study used health insurance claims data to examine the relationship between the length of sick leave and treatment administered to employees who received middle- to long-term accident and sickness benefits for ≥91 d due to mood disorders, anxiety, and dissociative, stress-related, somatoform and other nonpsychotic mental disorders. Employees who received psychotherapy had significantly shorter leaves of absence over one year compared to those that did not.

Characteristics of self-reported daily life note (LN) users in return-to-work judgment for workers on sick leave due to mental health conditions, and usefulness of the tool.
Authors: Kusumoto A, Kajiki S, Fujino Y, Namba K, Nagata T, Nagata M, Tsutsumi A, Mori K Abstract A self-reported daily life note (LN) is an effective tool used by occupational physicians to assess the capacity of workers on sick leave due to mental illness to return to work (RTW). We aimed to clarify whether there were differences in the criteria used to define recovery for RTW between LN users and non-users, whether LN users were satisfied with LN, and whether non-users wanted to use LN. In total, 363 occupational physicians (238 LN users, 125 non-users) completed self-reported questionnaires covering demographic...

The factors influencing the eating behaviour of shiftworkers: what, when, where and why.
Authors: Gupta CC, Coates AM, Dorrian J, Banks S Abstract Shiftwork leads to altered eating patterns, with workers often eating foods at all times across the 24h period. Strategies to reduce the burden of shiftwork on the workers should be prioritised and altering these eating patterns is an important area for change. This narrative review examines the current evidence on the individual and environmental factors influencing the eating behaviours of shiftworkers.

Research suggests that the functional movement screen (FMS) may provide practitioners the ability to identify tactical athletes most at risk for injury. However, there exists controversy as to the effectiveness of the FMS as a tool for classifying injury risk. The purpose of the meta-analysis was to determine the predictive value of the FMS in determining injury risk in workers engaged in tactical occupations.

Identifying shift worker chronotype: implications for health.
Authors: Hittle BM, Gillespie GL Abstract Shift workers are at risk for developing serious health issues due to short sleep. One cause of short sleep is circadian misalignment: sleep time is not synchronized with the body's natural circadian rhythms. Although circadian rhythms are strongly driven by the light/dark cycle, humans have individualized sleep time preferences (chronotypes) based on genetics, development, and external influences. Evening chronotype individuals fall asleep later than average and have a higher risk for developing various noncommunicable diseases. What is unclear is the association between c...

The cause of the accident appeared to be due to the Key-segment slipping out of the segment ring by the thrusting tailskin (wire brushes) of the TBM into the segment ring. This resulted in the collapse of the rings, causing the seabed ground and seawater to flow into the tunnel. We investigated how thin and thick segments without any circumferential joints behave under isotropic and anisotropic pressures using small-scal...
