Military hierarchy, job stress and mental health in peacetime

Oral habits and temporomandibular joint disorders according to stress levels among military personnel in South Korea: A cross-sectional study

BACKGROUND

Military personnel suffer from stress-induced temporomandibular joint disorders (TMD). No previous studies have evaluated the oral habits and TMD in military personnel based on their stress levels.

OBJECTIVES

To examine the correlation between oral habits and TMD based on stress levels. In addition, we assessed the relationship between stress levels and TMD by military rank as well as the impact of oral habits on TMD.

METHOD

This cross-sectional survey included 89 military personnel who visited the Armed Forces Medical Center in Korea with discomfort in the temporomandibular joint (TMJ) discomfort. Oral habits, stress level, TMD and general characteristics of the subjects were investigated. A questionnaire was distributed to the subjects who agreed to the study, and they were asked to respond in a self-written form. Multiple linear regression analysis was performed to examine the factors that affect oral habits and TMJ symptoms.

RESULTS

Stress scores and oral habits were highest in the 'Private' rank. In contrast, temporomandibular joint symptoms were highest in the 'Corporal' rank. Additionally, the high-risk stress group exhibited higher scores in oral habits and TMD compared to the potential stress group. Furthermore, there was a positive correlation between an increase in high-risk stress scores and a rise in oral habits. And individuals with more oral habits are at an increased likelihood of experiencing TMD.

CONCLUSION

Our study findings suggest that military personnel with prevent TMD and improve oral habits by addressing stress levels.

Effects of resilience training on mental, emotional, and physical stress outcomes in military officer cadets

Resilience is an important factor in counteracting the harmful effects of stress and is associated with healthy physiological and psychological responses to stress. Previous research has demonstrated the effectiveness of resilience fostering training programs in psychobiological stress response and recovery. Few studies, however, have examined training effects in real-life high-stress situations. In this study, we compare effects of a brief resilience training (RT) and an active control training in diversity management (DMT) on psychobiological stress response to and recovery from an intense military exercise of 81 male officer cadets. Five weeks after training completion, autonomic, endocrine, and subjective state measures of cadets were measured while undergoing stressful military exercise. The RT group perceived the military stressor as more challenging, and showed higher values in motivation and positive affect than the DMT group. Cortisol increased in both groups during stress, but showed a lower cortisol increase in the RT group thereafter. These results suggest that this brief resilience training helped cadets reframe the stressful situation in a more positive light, experiencing more positive emotions, and recovering faster from stress. To strengthen young military leaders in stressful situations, resilience promoting programs should become part of basic or leadership trainings.

The influence of job burnout on the attention ability of army soldiers and officers: Evidence from ERP

Job burnout is one of the most widespread mental problems in today's society and seriously affects the mental health and combat effectiveness of soldiers and officers. Herein, the effect of burnout on individual attention is studied from the perspective of neuroelectrophysiology. A total of 1,155 army soldiers and officers were included in this investigation and completed the Job Burnout Scale for Military Personnel. A total of 42 soldiers and officers were randomly selected from those with and without burnout to participate in an event-related potential (ERP) study using a visual oddball task. The characteristics of visual P3a and P3b at Fz, FCz, Cz, CPz, and Pz were recorded and analyzed by repeated-measures analysis of variance (ANOVA). P < 0.05 was the criterion for a significant difference. The total average score on the Job Burnout Scale for Military Personnel among the participants was 0.74 ± 0.46, and the detection rate of job burnout was 29.85%. In the Oddball task, the average number of target stimuli counted in the burnout group was lower than that in the control group, but no significant difference was found. For P3a, the Fz, FCz, Cz, CPz, and Pz amplitudes in the burnout group were significantly lower than those in the control group. The average amplitude of P3a evoked in the central parietal area was larger than that in the prefrontal area. For P3b, the amplitudes of the five electrodes in the burnout group were significantly lower than those in the control group. The average amplitude of P3b evoked in the parietal region was larger than those in the prefrontal and central parietal regions. A certain degree of job burnout is evident in army soldiers and officers. The voluntary attention and involuntary attention of individuals with burnout are both affected to some extent, as reflected by the lower amplitudes of P3a and P3b. The results suggest that P3a and P3b can be used as indicators to monitor cognitive neural function in soldiers and officers with burnout and can also be used as references for evaluating the effects of cognitive training and screening methods. In this study, ERP was used to research the attention ability of soldiers and officers with job burnout, and related issues were discussed from the aspects of the burnout results, behavioral results, ERP results, compensation effect of cognitive resources, application in the military field, limitations, and prospects.

Queen Bees: How Is Female Managers' Happiness Determined?

This paper aims to study the determinants of subjective happiness among working females with a focus on female managers. Drawn on a large social survey data set (N = 10470) in China, this paper constructs gender development index at sub-national levels to study how institutional settings are related to female managers' happiness. We find that female managers report higher levels of happiness than non-managerial employees. However, the promoting effect is contingent on individual characteristics and social-economic settings. The full sample regression suggests that female managers behaving in a masculine way generally report a high level of happiness. Meanwhile, female managers who refuse to support gender equality report low happiness levels. Sub-sample analysis reveals that these causalities are conditioned on regional culture. Masculine behavior and gender role orientation significantly predict subjective happiness only in gender-egalitarian regions. This study is one of the first to consider both internal (individual traits) and external (social-economic environment) factors when investigating how female managers' happiness is impacted. Also, this study challenges the traditional wisdom on the relationship between female managers' job satisfaction and work-home conflict. This study extends the literature by investigating the impacts of female managers' masculine behavior on their happiness. This study is useful for promoting female managers' leadership effectiveness and happiness.

Mental health problems and their related factors among seafarers: a scoping review

BACKGROUND

Seafarers are often reported to be engaged in a dangerous physical and psychosocial work environment. However, mental health status among seafarers has not been focused on compared with physical health issues. Systematic, comprehensive reviews of mental health problems and their relevant factors are lacking. This review aimed to clarify beneficial approaches to the mental health problems faced among seafarers using a scoping review to systematically map the evidence regarding mental health issues and their related factors.

METHODS

Studies were searched on MEDLINE/PubMed, Science Direct, Academic search complete using EBSCOhost databases, SCOPUS, EMBASE, and Web of science on 20, August 2020. This scoping review was conducted based on the framework of Arksey and O'Malley and Preferred Reporting items for Scoping Reviews flow diagram. The inclusion criteria were studies which determined the relationship between factors relevant to working conditions or working environment, and mental health in seafarers, and etc. Data were narratively summarized and reported.

RESULTS

Twenty-four were included in this review while two major findings were clarified. Firstly, the prevalence of stress, depressive symptoms, and burnout have been mentioned for decades. Secondly, factors related to mental health and psychological issues can be categorized as individual and work environmental factors. The individual factors include experience, age, health status (high BMI, poor sleep, and diabetics), and resilience. The work environmental factors consist of two parts. Job demands comprise pressure from contractors/customers/time, working hours, ship department, job title, voyage episodes, period of seafaring, noise, and vibration. The job resources included instrumental support, team cohesion, shipboard caring and effort-reward imbalance.

CONCLUSIONS

A beneficial approach to mental health problems faced among seafarers is necessary to understand comprehensively at individual and organization levels. Promoting health behaviors, training resilience, and managing obesity and chronic diseases comprise individual level strategies. Providing seafarers with adequate instrumental support, and practical support to communicate with customers, managing their distinct work-rest hours and adequate effort-reward balance comprise organization level methods.

Prevalence of common mental disorders among Brazilian workers: systematic review and meta-analysis

Abstract The aim of the present study was to summarize the prevalence of common mental disorders (CMD) among Brazilian workers through a systematic review and meta-analysis. Searches were conducted in SciELO, LILACS, PubMed, Scopus, and Web of Science. Articles were included if they had; an observational design, a sample of Brazilian workers, used a validated instrument and cut-off to assess CMD, and provided the prevalence value. A random-effect meta-analysis using professional categories as subgroups and a meta-regression were conducted. In total, 89 studies were included, with a total of 56,278 workers from 26 professional categories. The overall pooled prevalence of CMD was 0.30 (95%CI: 0.27-0.34), varying from 0.07 to 0.58. Professional categories that presented higher prevalences of CMD were: Prostitutes 0.58 (95%CI: 0.51-0.65), Social Educators 0.54 (95%CI: 0.50-0.59), Banking Workers 0.45 (95%CI: 0.44-0.47), Ragpickers 0.45 (95%CI: 0.40-0.49), and Teachers 0.40 (95%CI: 0.32-0.48). No other variable in addition to profession was associated with prevalence of CMD in the meta-regression analysis. Workers from the most affected professional categories should be monitored to prevent social, occupational, and health impairment from CMD.

Mental Health and Health Risk Behaviors of Active Duty Sexual Minority and Transgender Service Members in the United States Military

Purpose: The aim of this study was to examine health risk behaviors and mental health outcomes among sexual minority and transgender active duty military service members and their heterosexual and cisgender counterparts. Methods: Participants (N = 544) were recruited by using respondent-driven sampling between August 2017 and March 2018 and completed an online survey by using validated measures of cigarette smoking, alcohol use, anxiety, depression, post-traumatic stress disorder (PTSD), and suicidality. Bayesian random intercept multiple logistic regressions were used to understand differences between sexual minority participants and heterosexual participants as well as between transgender participants and both their cisgender sexual minority and cisgender heterosexual peers. Results: Cisgender sexual minority women service members were more likely to meet criteria for problematic alcohol use (adjusted odds ratio [aOR] = 10.11) and cigarette smoking (aOR = 7.12) than cisgender heterosexual women. Cisgender sexual minority men had greater odds of suicidality (aOR = 4.73) than their cisgender heterosexual counterparts. Transgender service members had greater odds of anxiety, PTSD, depression, and suicidality than their cisgender peers. Conclusion: Military researchers and policymakers who seek to improve the overall health and well-being of sexual minority and transgender service members should consider programs and policies that are tailored to specific health outcomes and unique sexual minority and transgender subgroups.

Psychological morbidity, quality of life, and self-rated health in the military personnel

OBJECTIVE

The mental health of military personnel varies as a result of different cultural, political, and administrative factors. The purpose of this study was to evaluate the psychological morbidity and quality of life of military personnel in Taiwan.

MATERIALS AND METHODS

This cross-sectional study utilized the World Health Organization Quality of Life Instrument, brief version, Taiwan version, the General Health Questionnaire-12, Chinese version, and the Visual Analog Scale (VAS) in several military units.

RESULTS

More than half of the subjects (55.3%) identified themselves as mentally unhealthy on the General Health Questionnaire-12, Chinese version; however, a higher percentage of officers perceived themselves as healthy (57.4%) than did noncommissioned officers (38.5%) or enlisted men (42.2%). Officers also had higher total quality of life (QOL) scores (83.98) than did enlisted men (79.67). Scores on the VAS also varied: officers: 72.5; noncommissioned officers: 67.7; and enlisted men: 66.3. The VAS and QOL were positively correlated with perceived mental health among these military personnel.

CONCLUSION

Our subjects had higher rates of perceiving themselves as mentally unhealthy compared to the general population. Those of higher rank perceived themselves as having better mental health and QOL. Improving mental health could result in a better QOL in the military. The VAS may be a useful tool for the rapid screening of self-reported mental health, which may be suitable in cases of stressful missions, such as in disaster rescue; however, more studies are needed to determine the optimal cut-off point of this measurement tool.

Effects of occupational stress on the gastrointestinal tract

The aim of this review is to provide a general overview of the relationship between occupational stress and gastrointestinal alterations. The International Labour Organization suggests occupational health includes psychological aspects to achieve mental well-being. However, the definition of health risks for an occupation includes biological, chemical, physical and ergonomic factors but does not address psychological stress or other affective disorders. Nevertheless, multiple investigations have studied occupational stress and its physiological consequences, focusing on specific risk groups and occupations considered stressful. Among the physiological effects of stress, gastrointestinal tract (GIT) alterations are highly prevalent. The relationship between occupational stress and GIT diseases is evident in everyday clinical practice; however, the usual strategy is to attack the effects but not the root of the problem. That is, in clinics, occupational stress is recognized as a source of GIT problems, but employers do not ascribe it enough importance as a risk factor, in general, and for gastrointestinal health, in particular. The identification, stratification, measurement and evaluation of stress and its associated corrective strategies, particularly for occupational stress, are important topics to address in the near future to establish the basis for considering stress as an important risk factor in occupational health.

Rank, job stress, psychological distress and physical activity among military personnel

Background

Physical fitness is one of the most important qualities in armed forces personnel. However, little is known about the association between the military environment and the occupational and leisure-time dimensions of the physical activity practiced there. This study assessed the association of rank, job stress and psychological distress with physical activity levels (overall and by dimensions).

Methods

This a cross-sectional study among 506 military service personnel of the Brazilian Army examined the association of rank, job stress and psychological distress with physical activity through multiple linear regression using a generalized linear model.

Results

The adjusted models showed that the rank of lieutenant was associated with most occupational physical activity (β = 0.324; CI 95% 0.167; 0.481); “high effort and low reward” was associated with more occupational physical activity (β = 0.224; CI 95% 0.098; 0.351) and with less physical activity in sports/physical exercise in leisure (β = −0.198; CI 95% −0.384; −0.011); and psychological distress was associated with less physical activity in sports/exercise in leisure (β = −0.184; CI 95% −0.321; −0.046).

Conclusions

The results of this study show that job stress and rank were associated with higher levels of occupational physical activity. Moreover job stress and psychological distress were associated with lower levels of physical activity in sports/exercises. In the military context, given the importance of physical activity and the psychosocial environment, both of which are related to health, these findings may offer input to institutional policies directed to identifying psychological distress early and improving work relationships, and to creating an environment more favorable to increasing the practice of leisure-time physical activity.

Association of work-related stress with mental health problems in a special police force unit

OBJECTIVES

Law and order enforcement tasks may expose special force police officers to significant psychosocial risk factors. The aim of this work is to investigate the relationship between job stress and the presence of mental health symptoms while controlling sociodemographical, occupational and personality variables in special force police officers.

METHOD

At different time points, 292 of 294 members of the 'VI Reparto Mobile', a special police force engaged exclusively in the enforcement of law and order, responded to our invitation to complete questionnaires for the assessment of personality traits, work-related stress (using the Demand-Control-Support (DCS) and the Effort-Reward-Imbalance (ERI) models) and mental health problems such as depression, anxiety and burnout.

RESULTS

Regression analyses showed that lower levels of support and reward and higher levels of effort and overcommitment were associated with higher levels of mental health symptoms. Psychological screening revealed 21 (7.3%) likely cases of mild depression (Beck Depression Inventory, BDI≥10). Officers who had experienced a discrepancy between work effort and rewards showed a marked increase in the risk of depression (OR 7.89, 95% CI 2.32 to 26.82) when compared with their counterparts who did not perceive themselves to be in a condition of distress.

CONCLUSIONS

The findings of this study suggest that work-related stress may play a role in the development of mental health problems in police officers. The prevalence of mental health symptoms in the cohort investigated here was low, but not negligible in the case of depression. Since special forces police officers have to perform sensitive tasks for which a healthy psychological functioning is needed, the results of this study suggest that steps should be taken to prevent distress and improve the mental well-being of these workers.

Prevalência de transtornos mentais comuns em jovens brasileiros recém-incorporados ao Serviço Militar Obrigatório e fatores associados

A saúde mental de militares das Forças Armadas é uma área de investigação ainda pouco explorada no Brasil. O presente estudo teve por objetivo estimar a prevalência de transtornos mentais comuns (TMC) e identificar os fatores a estes associados em jovens brasileiros recém-incorporados ao serviço militar obrigatório: os recrutas. A população de estudo foi composta de 78 jovens adultos do sexo masculino. A ocorrência de TMC (variável dependente) foi avaliada por meio do General Health Questionnaire, versão 12 itens (GHQ-12). Para estimar as associações entre TMC e as variáveis independentes foram utilizados o teste χ²(Qui-quadrado)e a regressão logística. Os resultados mostraram uma prevalência de TMC de 43,6% (IC 95% 33,14 - 54,64). As razões de prevalência de TMC mostraram-se entre 4 e 5 vezes maiores entre os que apresentavam distúrbios do sono, sendo que estes se mostraram como único fator associado a TMC. Estes resultados parecem indicar que as situações vivenciadas pelos recrutas em seu ambiente de trabalho podem estar associadas com TMC de forma causal. Outros estudos, com desenho longitudinal, são necessários para que tal efeito seja confirmado.
