Job burnout is rampant in workplaces and has become an important global public health concern. It is one of the top occupational health problems to be addressed in the workplace in Europe and America. The prevalence rate of job burnout is also at a high level in China, and cannot be ignored for its associated health loss and economic impact of occupational population, so we should deepen the understanding of job burnout hazards, promote relevant scientific research, and develop associated prevention and control programs. This paper introduced the epidemic status of job burnout, health hazards and economic impact, development stage, influencing factors, conceptual models, measurement and evaluation methods, and prevention and control measures, and proposed scientific research directions as well as prevention and control strategies of job burnout in the future.

Job burnout is a hot topic in occupational health psychology research at home and abroad. This paper reviewed the concept and development of job burnout, introduced the common tools measuring job burnout, indicated the problems reported in the measurement tools of job burnout, proposed suggestions on the introduction, translation, development and use of burnout measurement tools, summarized the new trend of research on job burnout abroad, and prospected the future research work of job burnout in China.

OBJECTIVETo study the effects of exposed to different concentrations of carbon disulfide on neurological signs of workers.

METHODSCollection the information of concentration of carbon disulfide in the workplace or workers individuals exposed of a chemical fiber industry from 2004 to 2011, a total of 3 537 workers exposed to carbon disulfide were detected muscle strength and muscle tone, knee reflex, Achilles tendon reflex, trembling limbs, sensory function, and three chatter. Chi-square test was used for statistical analysis on abnormal neurological signs of workers.

RESULTSEight hours time-weighted average concentration range of workers exposed to carbon disulfide in this chemical fiber industry was 0.2-41.0 mg/m(3), geometric mean was 2.38 mg/m(3). Concentration of carbon disulfide exposure of 1 771 workers was from 0.2 to 2.5 mg/m3( ≤ 2.5 mg/m(3)), 642 workers was 2.6-4.8 mg/m(3) (< 5.0 mg/m(3)), other 1 051 workers was from 5.1 to 41.0 mg/m(3) ( > 5.0 mg/m(3)) in all subjects. The different detection rates of knee reflex were 3.0% (31/1 045), 3.7% (21/574), 4.8% (16/331), 3.3% (10/305), 5.9% (11/187), 6.7% (68/1 022), the different detection rates of Achilles tendon reflex were 2.2% (23/1 045), 3.7% (21/574), 2.7% (9/331), 2.3% (7/305), 2.1% (4/187), 5.6% (57/1 022), the different detection rates of sensory dysfunction were 0.4% (4/1 045), 0.5% (3/574), 0.6% (2/331), 0.0% (0/305), 2.1% (4/187), 1.7% (17/1 022) in different cumulative amount of contact groups ( ≤ 10.0, 10.1-20.0, 20.1-30.0, 30.1-40.0, 40.1-50.0, >50.0 mg/m(3) per year), and the differences were statistically significant (χ(2) = 19.53, 21.27 and 15.89, all P values were <0.01) . Stratified according to age and gender, in addition to the ≤ 25 years group the difference of detection rate analysis on Achilles tendon reflex was statistically significant in the different concentration group (the ratio of on Achilles tendon reflex in the different groups of concentration of carbon disulfide exposure of 2.5, 2.6-5.0, ≥ 5.0 mg/m(3) were 0.4% (2/511), 1.0% (1/98), 2.1% (7/327), χ(2) = 5.59, P = 0.045) , the difference of detection rate analysis on neurological sign was not statistically significant in the different concentration group on the rest of the age and gender groups (P > 0.05).

CONCLUSIONWithin the concentration range of the object of study contact actual, different concentrations of carbon disulfide in addition to individual neurological signs of individual ages influential, it has no significant effect on the various signs of nervous system of workers of most age and gender groups, expect the age below the 25 years old group.

OBJECTIVETo investigate the relationship between work in shifts and occupational stress.

METHODSA total of 5338 employees from 13 companies were investigated by cluster sampling, and occupational stress measuring tools, job content questionnaire, and effort-reward imbalance questionnaire were used to investigate occupational stress factors, stress reaction, and the condition of work in shifts.

RESULTSThe employees who worked in shifts accounted for 46.6%. The condition of work in shifts varied significantly across different companies, employees with different individual features (including sex, job title, degree of education, age, working years, smoking, and drinking), and employees with different weekly working times(P<0.01 or P<0.05); health status was associated with work in shifts(P<0.01); compared with the employees who did not work in shifts, those who worked in shifts had significantly lower scores of technology utilization, work control level, psychological need, reward, social support, and job satisfaction(P<0.01 or P<0.05), as well as significantly higher scores of physical demands, effort, depressive symptoms, and negative affectivity(P<0.01).

CONCLUSIONWork in shifts can affect health status, and is associated with occupational stress.

OBJECTIVETo investigate the relationship between emotion and plasma fibrinogen level in train crew.

METHODSA cross-sectional study was conducted in 350 male workers of passenger car, freight car, shunting locomotive for passenger service, and high-speed car from a locomotive depot. The factors involved in this study were as follows: common factors including educational level, physical exercise, smoking, drinking, and physical environment, emotional/characteristic factors including sleep quality, depression, and coping strategies, and working -related factors including effort -reward imbalance, working age, responsibility for people, responsibility for work, intragroup conflicts, and intergroup conflicts. Variables were measured with common rating scales at home and abroad. Plasma fibrinogen level was determined by immunological turbidimetry. The Spearman rank correlation test and multiple stepwise regression were used to analyse the influential factors for fibrinogen level. The original concentration of fibrinogen was subjected to logarithmic transformation in statistical analysis.

RESULTSThe Spearman rank correlation test showed that plasma fibrinogen level was significantly correlated with age(r = 0.228, P = 0.001), working age(r = 0.231, P = 0.001), and emotion (r = -0.138, P = 0.016), but showed no significant relationship with other variables (P > 0.05). The multiple stepwise regression with fibrinogen level as a dependent variable was performed in four models. Model 1 showed that emotion and age were included in the regression after adjustment for common factors (P < 0.05). Model 2 also showed inclusion of emotion and age in the regression after adjustment for common factors and occupational stress factors (P < 0.05). Model 3 showed inclusion of emotion in the regression after adjustment for common factors, occupational stress factors, and psychological factors (P < 0.05). Model 4 showed inclusion of emotion and age after adjustment for common factors, occupational stress factors, psychological factors, and relief factors (P < 0.05).

CONCLUSIONThe emotion of train crew is correlated with plasma fibrinogen level.
