BACKGROUND: Menopausal disorders include obscure symptomatology that greatly reduce work productivity among female workers. Quantifying the impact of menopause-related symptoms on work productivity is very difficult because no such guidelines exist to date. We aimed to develop a scale of overall health status for working women in the perimenopausal period. METHODS: In September, 2021, we conducted an Internet web survey which included 3,645 female workers aged 45-56 years in perimenopausal period. We asked the participants to answer 76 items relevant to menopausal symptomatology, that were created for this study and performed exploratory and confirmatory factor analyses for the scale development. Cronbach's alpha, receiver operating characteristic analysis, and logistic regression analysis were used to verify the developed scale. RESULTS: Approximately 85% participants did not have menstruation or disrupted cycles. Explanatory factor analysis using the maximum likelihood method and Promax rotation identified 21 items with a four-factor structure: psychological symptoms (8 items, α = 0.96); physiological symptoms (6 items, alpha = 0.87); sleep difficulty (4 items, alpha = 0.92); human relationship (3 items, alpha = 0.92). Confirmatory factor analyses found excellent model fit for the four-factor model (RMSR = 0.079; TLI = 0.929; CFI = 0.938). Criterion and concurrent validity were confirmed with high correlation coefficients between each of the four factors, previously validated menopausal symptom questionnaire, and Copenhagen Burnout Inventory scales, respectively (all ps < 0.0001). The developed scale was able to predict absenteeism with 78% sensitivity, 58% specificity, and an AUC of 0.727 (95%CI: 0.696-0.757). Higher scores of each factor as well as total score of the scale were more likely to be associated with work absence experience due to menopause-related symptoms even after adjusting for Copenhagen Burnout Inventory subscales (all ps < 0.0001). CONCLUSION We found that the developed scale has high validity and reliability and could be a significant indicator of absenteeism for working women in perimenopausal period.

Objective: To investigate the level of psychosocial factors in workplace and their health effects among workers in a natural gas field. Methods: A prospective and open cohort of natural gas field workers was established to study the level of workplace psychosocial factors and their health effects, with a follow-up every 5 years. In October 2018, a cluster sampling method was used to conduct a baseline survey of 1737 workers in a natural gas field, including a questionnaire survey on demographic characteristics, workplace psychosocial factors and mental health outcomes, physiological indicators such as height and weight, and biochemical indicators such as blood routine, urine routine, liver function and kidney function. The baseline data of the workers were statistically described and analyzed. The psychosocial factors and mental health outcomes were divided into high and low groups according to the mean score, and the physiological and biochemical indicators were divided into normal and abnormal groups according to the reference range of normal values. Results: The age of 1737 natural gas field workers was (41.8±8.0) years old, and the length of service was (21.0±9.7) years. There were 1470 male workers (84.6%). There were 773 (44.5%) high school (technical secondary school) and 827 (47.6%) college (junior college) graduates, 1490 (85.8%) married (including remarriage after divorce), 641 (36.9%) smokers and 835 (48.1%) drinkers. Among the psychosocial factors, the detection rates of high levels of resilience, self-efficacy, colleague support and positive emotion were all higher than 50%. Among the mental health outcomes evaluation indexes, the detection rates of high levels of sleep disorder, job satisfaction and daily stress were 41.82% (716/1712), 57.25% (960/1677) and 45.87% (794/1731), respectively. The detection rate of depressive symptoms was 22.77% (383/1682). The abnormal rates of body mass index (BMI), triglyceride and low density lipoprotein were 46.74% (810/1733), 36.50% (634/1737) and 27.98% (486/1737), respectively. The abnormal rates of systolic blood pressure, diastolic blood pressure, uric acid, total cholesterol and blood glucose were 21.64% (375/1733), 21.41% (371/1733), 20.67% (359/1737), 20.55% (357/1737) and 19.17% (333/1737), respectively. The prevalence rates of hypertension and diabetes were 11.23% (195/1737) and 3.45% (60/1737), respectively. Conclusion: The detection rates of high level psychosocial factors in natural gas field workers are high, and their effects on physical and mental health remain to be verified. The establishment of a cohort study of the levels and health effects of psychosocial factors provides an important resource for confirming the causal relationship between workplace psychosocial factors and health.

OBJECTIVES: Health workers are at risk of workplace violence, which can seriously affects their mental health and work status. This study aims to explore the mediating role of depression between workplace violence and job burnout among healthcare workers. METHODS: From January 10 to February 5, 2019, a questionnaire was distributed to frontline healthcare workers through the wenjuanxing platform using convenient sampling (snowball sampling). The questionnaire included the Chinese version of the Workplace Violence Scale, Maslach Burnout Inventory, and Patient Health Questionnaires (PHQ-2). Descriptive statistics, correlation analysis, and mediation model tests were conducted on the cross-sectional data collection. RESULTS: The study included 3 684 participants, with (31.63±7.69) years old. Among them 2 079(56.43%) were experienced workplace violence, 687(18.65%) were screened positive for depression, and 2 247(60.99%) were experienced high levels of occupational burnout. Correlation analysis showed positive association between workplace violence and depression, workplace violence and occupational burnout, depression and occupational burnout (r=0.135, r=0.107, r=0.335, respectively, all P<0.001). After controlling for covariates, workplace violence had an indirect effect on occupational burnout through depression, with a standardized coefficient of 0.25 (SE=0.02, 95% CI 0.21 to 0.28), accounting for 13.87% of the total effect. CONCLUSIONS The study highlights the close relationship between workplace violence, depression, and occupational burnout among healthcare workers, with depression acting as a mediator between workplace violence and occupational burnout. This study suggests that it is necessary to improve the communication skills of healthcare workers, increase the installation of security systems and emergency plans, use new media platforms to convey positive energy between doctors and patients, and open channels for medical consultation and complaints. It is also necessary to provide guidance for healthcare workers' depressive emotions. Addressing depression among health care workers will help reduce the harm caused by workplace violence, protect the physical and mental health of healthcare workers, and reduce work burnout.

BACKGROUND AND AIM: A healthy work environment is one in which workers and managers cooperate in the process of continuous improvement regarding the protection, and promotion of workers' health and well-being, for the sake of work sustainability. The current state of the art shows that an unfavourable work environment contributes to nurses' dissatisfaction, burnout and emotional exhaustion, and the intention to leave the workplace/service. This study aimed to identify the Nurses' Work Environment in a small Portuguese Hospital, diagnose the situation, and focus on a healthy work environment. METHODS AND MATERIALS: This is a quantitative, descriptive, and cross-sectional study, with a convenience sample of 90 nurses. The “Escala de Ambiente de Trabalho da Prática de Enfermagem” (Nursing Practice Work Environment Scale), validated and adapted by Ferreira & Amendoeira (2014) for the Portuguese population, was applied. The statistical treatment was performed using SPSS 27. RESULTS: The sample is mostly composed of female nurses (87%) with an average age of 26 years, and 75.5% are single. The dimension "Management and Leadership of the Head Nurse" had a mean value of x̅ =3.3 (out of 4) and σ=0.5, which was the dimension with the best assessment. The dimension with less encouraging results was "Nurses' Participation in Hospital Affairs" with x̅ =2.8 (out of 4) and σ=0.7. Overall, all domains assessed had a mean value above 2.5, which was considered a favourable work environment by the nurses. CONCLUSION The results, although generally satisfactory, show the need to carefully intervene and assess each dimension in an integrated perspective, to promote a healthy work environment and workers' well-being, since its imbalance may negatively affect quality of their work, impacting the quality of health care provided to the user . In addition, these results should be understood as an important factor to be considered in the design of future care teams. Regardind future research, it would be important to consider large samples and deepen the topic explored among different departments in the health care facilities.

Objective: To explore the influence mechanism of intrusive thoughts and ego depletion between effects of workplace violence on burnout sense in clinical nurses. Methods: In May 2019, 10 cities in Henan Province and Fujian Province were selected as sampling cities by the method of grabbing random balls. Using the stratified cluster sampling method, nurses in clinical nursing posts in 22 third class hospitals and 23 second class hospitals were selected as the research objects for a cross-sectional epidemiological survey, including 1200 nurses. A total of 1159 valid questionnaires were collected, and the effective rate was 96.6%. 1159 clinical nurses were investigated by workplace violence scale, event impact scale, self-regulation fatigue scale and job burnout scale. The items contained in the questionnaire were analyzed by exploratory factor analysis with Harman single factor test, and the demographic characteristics of nurses' workplace violence, invasive thinking, self loss and job burnout were compared and analyzed with s-n-k. Results: Those with less than 3 years of service, those with more than 3 years of aggressive thinking and self loss score, and those with less than 3 years of job burnout score; The score of job burnout of unmarried was lower than that of married; The scores of invasive thinking and self loss of non editors were higher than those of current editors; The scores of workplace violence, aggressive thinking, self loss and job burnout of clinical nurses in tertiary hospitals were higher than those in secondary hospitals; The score of job burnout of undergraduate and above is higher than that of junior college and below; The scores of workplace violence, aggressive thinking and self loss of clinical nurses in surgical departments were higher than those in non-surgical departments; The job burnout score of those aged 36 and above was higher than that of those aged <36, The difference was statistically significant (P< 0.05) . Aggressive thinking and self attrition played a mediating role between workplace violence and job burnout. Workplace violence affected job burnout through the single mediating role of aggressive thinking, the single mediating role of self attrition, and the chain mediating role of aggressive thinking self attrition (β=0.16、0.08、0.03, 95%CI: 0.251~0.190、0.121~0.028、0.050~0.012, P<0.05) . Conclusion: Workplace violence affects burnout sense through the independent mediating role of intrusive thoughts and ego depletion and the chain mediating role of intrusive thoughts and ego depletion in clinical nurses.
