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.

Occupational stress is one of the major occupational health problems in industrialized countries. In Europe, the United States, Japan, and other countries, occupational stress has been included in the prevention and control of occupational hazards in the workplace. This problem has also become a major risk factor affecting the physical and mental health of the working population in China. Over the last three decades, China had carried out a lot of research on occupational stress and made significant progress, but there is still a big gap between China and industrialized countries in terms of theoretical research on occupational stress, development of measurement tools, research topics and methods, formulation of regulations and standards, and practice of prevention and control. Articles in this key issue report the research on the core scale of occupational stress measurement for the Chinese working population, the scale scoring norm of manufacturing and medical personnel, the research on the relationship between positive psychology variables, and occupational stress and its role in the relationship between occupational stress and health outcomes.
