Analysis of Occupational Stress and Its Relationship with Secretory Immunoglobulin A in the Xinjiang Plateau Young Military Recruits

Abstract

Background. With the continuous improvement of the modernization of the Chinese military and the major adjustments made by the state to the recruitment policy, the newly recruited military undergone multiple pressures such as targeted high-intensity military training and environmental changes. The mental health of military has become a crucial factor of improving the fighting capacity effectiveness of the troops. Objectives. To explore occupational stress of young recruits in the Xinjiang plateau environment during their basic military training period and analyze the relationship between occupational stress and secretory immunoglobulin A (sIgA) levels. Methods. Using multistage stratified cluster random sampling, 625 recruits stationed at Xinjiang plateau command in 2014 were enrolled as subjects. Occupational stress was assessed by the Occupational Stress Inventory Revised Edition (OSI-R). sIgA in saliva was quantified by enzyme-linked immunosorbent assay. The resulting data were analyzed using descriptive statistics, nonparametric tests, and correlation analysis. Results. Based on demographic characteristics, occupational stress was higher in the urban group than the rural group, coping ability for stress was greater in individuals who were students before joining the army than nonstudents, occupational stress was higher in smokers than nonsmokers, and coping ability for stress was higher in nonsmokers than in smokers (all P<0.05). Being an only child, educational level and age were not significantly related to occupational stress scores (P>0.05). Salivary sIgA level was higher in the high occupational stress group than in the low stress group (P<0.01). Salivary sIgA was positively correlated with scores on the occupational role and personal strain questionnaires (rs=0.229, rs=0.268, P<0.01). Conclusion. Demographic characteristics influenced occupational stress among young recruits in cold and high-altitude area. Further, there were some relationships between occupational stress and salivary sIgA in young military recruits.

Effect of 1% H2O2 on Three Salivary Stress Biomarkers, Cortisol, Alpha-Amylase, and sIgA

“…Previous research has suggested that acute stress caused by environmental changes can result in an increase in s-IgA synthesis as an adaptive response by the body. 65 One study reported that the increase in s-IgA concentration occurred within the first 15 minutes of acute stress and was reduced to baseline levels, thereafter; although salivary cortisol levels increased and were mainatained due to continued stress. 54 In our study, acute stress might occur during the first saliva collection during adaptation to a new environment, whilst the levels of salivary cortisol may not increase in the absence of stress.…”

Exploring links between Chinese military recruits' psychological stress and coping style from the person-environment fit perspective: The chain mediating effect of self-efficacy and social support

“…Under such circumstances, the choice of their coping style is related to the army's combat effectiveness, especially in psychological warfare plays a decisive and dominant role. Therefore, efforts to improve their psychological stress coping ability and coping style selection can help improve military mission execution effectiveness (Tao et al, 2020).…”

Promotion of Intelligent Digital Computer-Aided Design to the Improvement of Rural Public Environment Design

“…Tao et al mentioned that on the basis of adhering to the traditional architectural features, most of the rural architectural features of Japan still maintain the original form, and the application of building materials is rarely affected by western architectural standards, which is highly humanistic. is feature is also inseparable from the attitude of Japanese rural residents in actively participating in the construction of new villages and controlling the architectural features and forms [18]. On the basis of existing research, this paper proposes to develop and research a digital design platform based on digital computer model, and take parallel robot (Cross IV) as the object.…”
