OBJECTIVE: To analyze the factors associated with mental distress among health workers who cared for patients with a suspected or confirmed diagnosis of coronavirus disease 2019 (COVID-19). METHODS: A cross-sectional analytical study of national scope, carried out between in the second quarter of 2020. A total of 437 health professionals, who filled out an electronic form about sociodemographic data, occupational aspects, psychosocial characteristics of work and mental distress. Multiple logistic regression was performed to analyze the covariables associated with mental distress. RESULTS: There was a predominance of workers on the nursing team (65.0%), female (71.0%), from Southeastern region of the country (68.6%) and with no morbidities (36.2%). The prevalence of mental distress was 61.6%. Job strain was reported by 24% of participants, and the perception of low support from coworkers was described by 52.9%. The final multiple regression model showed that mental distress was associated with females (odds ratio - OR: 1.93; 95%CI: 1.22-3.07), age up to 40 years (OR: 1.64; 95%CI: 1.07-2.52), weekly working hours equal or over 60 hours (OR: 1.87; 95%CI: 1.15-3.11), job strain (OR: 2.45; 95%CI: 1.41-4.40) and low support from co-workers (OR: 3.47; 95%CI: 2.26-5.38). CONCLUSION: Six out of ten participants presented mental distress, which was associated to both individual characteristics and factors related to the work carried out during the pandemic. There is an urgent need to map services that have such characteristics, to outline actions to promote mental health and prevent emotional distress at different levels of health care.

einstein (São Paulo). 2021;19:1-8 psicossociais do trabalho e sofrimento mental. Foi realizada regressão logística múltipla para analisar as covariáveis associadas ao sofrimento mental. Resultados: Predominaram trabalhadores da equipe de enfermagem (65,0%), do sexo feminino (71,0%), da região Sudeste do país (68,6%) e sem morbidades (36,2%). A prevalência de sofrimento mental foi de 61,6%. O trabalho de alta exigência psicossocial foi informado por 24% dos participantes e a percepção de baixo apoio dos colegas de trabalho foi relatada por 52,9%. O modelo de regressão múltiplo final demonstrou que o sofrimento mental estava associado a: sexo feminino (razão de chance -RC: 1,93; IC95%: 1,22-3,07), idade até 40 anos (RC: 1,64; IC95%: 1,07-2,52), jornada semanal de trabalho igual ou superior a 60 horas (RC: 1,87; IC95%: 1,15-3,11), trabalho de alta exigência (RC: 2,45; IC95%: 1,41-4,40) e baixo apoio dos colegas (RC: 3,47; IC95%: 2, 38) . Conclusão: Seis em cada dez participantes apresentavam quadro de sofrimento mental associado tanto a características individuais, quanto a fatores relacionados ao trabalho realizado durante a pandemia. É urgente a necessidade de mapear os serviços que tenham tais características, para delinear ações de promoção da saúde mental e prevenção do desgaste emocional nos diversos níveis de atenção em saúde.

In March 2020, the World Health Organization (WHO) declared a global state of emergency due to the coronavirus disease 2019 (COVID- 19) , caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a rapidly spreading etiologic agent that causes severe disease. (1, 2) It brought repercussions not only to people affected by the disease, but also to healthcare workers responsible for their care. Contamination and illness of professionals involved in patient care are realities in the pandemic, including the record of 364 deaths of healthcare workers due to this infection up to the 49 th epidemiological week of 2020, in Brazil. (3) There is an urgent need to monitor these groups with greater potential for illness, based on the actions of specific sectors, such as the frontline of health care. (4) The patient care services underwent abrupt organizational and environmental changes, culminating in modification of their routines. Work intensification was revealed as one of the main characteristics of this process, especially regarding health care activities at the various levels of care. Overcrowded units, lack of equipment, and beds for hospitalization, are problems in the organization of work that impacted the health of the teams in this pandemic context. (5, 6) The psychosocial stressors at work can trigger negative emotions of the frontline professionals working against the epidemic, requiring coping strategies for maintenance of their mental health. (7) Therefore, one should reflect on the different possibilities of illness in healthcare workers, beyond the diagnosis of COVID- 19. In this perspective, the recognition of the state of vulnerability, together with the uncertainties experienced in the pandemic period, can have a negative influence on the well-being of healthcare workers. (7) Those who are in direct and frequent contact with patients with suspected or confirmed infection tend to present with a greater risk of psychological overload, (8) and development of both depressive and anxious conditions. (7, 9, 10) Brazilian data from the Instituto Nacional de Seguro Social (INSS) [National Institute of Social Security] indicate, in recent years, such diagnoses are the most frequent reasons for grant disability benefits due to psychiatric illnesses among workers in Brazil. Thus, the early recognition of signs of psychological distress can help in the direction of adequate support and care, to protect the physical and mental health of this group. (10) ❚ OBJECTIVE To analyze the factors associated with mental suffering among healthcare workers who were caring for patients with suspected or confirmed diagnosis of COVID-19.

An analytical cross-sectional study, conducted between April and June 2020, contemplating data from the first phase of the research entitled Potentials for Strain and Strengthening of Healthcare Workers Acting in Coronavirus Disease 2019 (COVID-19) Care Settings, developed at the Faculdade de Enfermagem da Universidade do Estado do Rio de Janeiro (FE-UERJ) and partner organizations.

It was a convenience sample, considering the limitations of face-to-face access of the research subjects and organizations at the critical moment of increase in cases seen in Brazil. Health professionals from several areas, working at all levels of the frontline of care for patients with COVID-19, were invited. The invitation was made through virtual dissemination, via email and social networks, which included the website address with a form to collect sociodemographic data (sex, age, and region of the einstein (São Paulo). 2021;19:1-8 country where they lived/worked), occupational data (profession, level of care, complexity of health care, characterization of employment status, weekly work hours, and psychosocial factors of work), and clinical data (clinical morbidities and mental distress).

To evaluate the psychosocial characteristics of work, we used the validated version in Brazilian Portuguese of the Job Stress Scale (JSS), (11) based on the model that discusses the workers´ perceptions about the interface between qualitative and quantitative demands of the job, the decision latitude to perform tasks, and the support offered by supervisors and colleagues. (12) The questionnaire contains 17 items, with four response options, on a Likert scale, to evaluate the three dimensions. (11) In assessing mental distress, we used the version validated for Brazilian Portuguese of the Self-Reporting Questionnaire (SRQ-20), developed by the WHO for screening mental disorders. (13, 14) There are 20 questions about symptoms of depression, anxiety, and stress, with a dichotomous response (yes/no). Mental suffering is considered when there are seven or more positive responses, regardless of the participant's sex. (15) Numerical data were presented by means of descriptive statistics (frequencies, means, and standard deviation), and were categorized for analysis. The categorical independent variables were submitted to the test χ 2 with the outcome of mental distress. Variables with p≤0.20 were selected for the multiple logistic regression model, built with the inclusion of variables according to the increasing order of p value. The stepwise forward method was used, maintaining in the modeling the variables associated with the outcome (p≤0.05), presenting the odds ratio (OR) of the univariate and multiple regression, as well as the 95% confidence interval (95%CI). Data were tabulated in Microsoft ® Excel ® spreadsheets for Office 365 MSO, version 16 

The group participating in the study comprised 437 healthcare workers. Their characteristics are presented on table 1. Most participants were from the nursing staff (65.0%), with a mean age of 38.4 years (standard deviation -SD±10.0). Most were female (71.0%), living and working in the Southeast region of Brazil (68.6%), and with no morbidities (63.8%). The prevalence of mental distress was 61.6%. Most of them were employed only in the public health network (70.1%), in a single organization (60.9%), with a workload of 40 to 59 hours per week (49.3%), under a labor contract (33.3%), and most often working in Primary Care (31.5%).

As for the psychosocial characteristics of the work, the high job strain, with high level of demands and low control over the work, was reported by 24% of participants. The perception of low support from coworkers was described by the majority (52.9%).

The variables sex, age group, occupation, weekly working hours, morbidities, and psychosocial characteristics of the work, including social support, were selected for logistic regression modeling. In the multiple model, it was observed female participants had a greater than 93.0% odds of reporting mental suffering than males; and those younger than 40 years had a 64.0% greater odds of mental distress than those aged 40 years or older. Regarding characteristics of the work organization, workloads of 60 hours a week or more increased by 87.0% the odds of the outcome among participants of the group. The odds of mental suffering in the group studied was 2.45 times greater when the work was characterized as highly demanding, and 3.47 times greater when there was a perception of low social support at work ( 

The prevalence of mental suffering found in the present study is higher than that of other national surveys before the pandemic caused by SARS-CoV-2, which analyzed samples of healthcare workers from different areas, and used the same cut-off point in the SRQ-20, indicating a prevalence variability between 21% and 42.6% of mental distress. (16) (17) (18) The higher rate of cases found in the present study can be explained by the aspects inherent to the context of the COVID-19 pandemic and its impacts throughout society, particularly among healthcare workers. (6) A Brazilian population-based study with more than 45 thousand individuals conducted during the first half of 2020, found that 40.4% of participants often felt sad or depressed, and 52.6% felt anxious or nervous. (19) As for healthcare workers, in Asia, a systematic review of 13 studies conducted during the pandemic with more than 33 thousand participants measured a combined prevalence of anxiety in 23.2% and depression in 22.8%. (9) Those who were on the frontline and involved in direct care of patients with viral infection were at higher risk of depression, anxiety, insomnia, and stress. (20) Since this Brazilian study used the WHO questionnaire, which addresses less specific psychoemotional signs and symptoms, its result may generate a broader estimate of mental distress, and for this reason, it is indicated for screening in health services. (14) The predominance of female participants in the sample is consistent with global data, indicating a higher frequency of women in the healthcare workforce (70%). (21) Data from the present study demonstrated the odds of mental distress among female Brazilian workers was twice as high as among men. In Asia, female healthcare workers had a higher frequency of depressive (26.9% versus 20.3%) and anxious (29.1% versus 20.9%) symptoms, (9) in addition to more severe mental disorders. (20) This difference between sexes has several psychosocial explanations related to work context, such as women's lower pay and occupation of less valued positions within the context of health sector of economy. (21) The issue of the double burden (work-home) may be a relevant factor for this result, considering the risk of increasing the overall workload in this pandemic scenario, with the intensification of work and home tasks.

Participants younger than 40 years had a higher odds of mental distress, a result that is in line with prepandemic data. (22, 23) In a study conducted in the United Kingdom during the global SARS-CoV-2 outbreak, there was no difference between age groups regarding psychological symptoms, (10) but in previous viral outbreak scenarios, younger workers and those with less experience were more likely to present psychoemotional disorders. (24) One hypothesis for this result would be that older workers, and probably those with more years of occupation, developed strategies that allowed less traumatic coping with the personal and professional stressors arising from the COVID-19 setting.

No difference was found in the frequency of mental distress among the occupations of the research participants. However, a systematic review indicated that the nursing team had a higher frequency of depressive and anxious conditions than did the medical staff; (9) and a Chinese study showed more severe symptoms among nursing staff. (20) Perhaps the complexity of the Brazilian pandemic context, with collective stressors of the work environment and organization, promoted an equanimous negative impact among professionals, regardless of the specific issues of each job. For example, the unavailability of personal protection equipment and work overload, (25) in addition to the fear of being contaminated, may be common and frequent psychological stressors among those who are on the frontline of patient care. (8) The qualitative study with nursing professionals in China showed the team exhibited both positive and negative feelings during the pandemic, requiring the development of individual and collective coping strategies to mitigate the negative impacts of work, and to maintain their professional performance. (7) The review by Shaukat et al., (6) relates mental distress to psychosocial conditions of work of healthcare professionals during this pandemic. The data from the present Brazilian study showed psychosocial work characteristics were significantly associated with mental suffering. The high job strain, with high qualitative and quantitative demand of tasks and low decision latitude to perform them, was not a frequent characteristic among participants, but it increased the odds of illness under study by almost 150%. In Germany, increased workload and organizational changes were found to be associated with burnout and psychological distress among healthcare workers. (8) Other studies conducted with healthcare workers before the pandemic found similar results regarding the association between toxic work stressors and mental distress. (16, 18) In addition to the stressors common to work in health services, there are probably characteristics inherent to the Brazilian public health system, such as job strain, reduced availability of supplies, and precarious labor relations, which may have been aggravated by the scenario of fighting COVID-19. (26) Another example of work stressors is the long working day. A weekly workload of 60 hours or more increased the chance of fatigue in the group studied. With an increase in the overall workload, the change in work organization after the onset of the pandemic was associated with depression (OR: 2.00; 95%CI: 1.33einstein (São Paulo). 2021;19:1-8 3.02) and anxiety (OR: 2.24; 95%CI: 1.50-3.36) among healthcare workers in China. (27) After all, a longer workday like that of the participants in this study, increases the time in contact with negative aspects at work, deteriorating physical and emotional health. (28) In a scenario of infection risk, management of the effectiveness of actions to protect workers from the biological agent should be permanent. (6) In Germany, workers suggested actions to improve working conditions during the pandemic, such as adaptation of teams to the demand for services, clarity in organizational and planning guidelines, and better communication between managers and the team. (8) China, the first country affected by the infection, established guidelines (29) to control the negative impact of the pandemic on workers' health, such as the balance between working and resting hours, strengthening safety actions, and offering health support. (28) The perception of good relationships among coworkers and managers can influence health positively. (12) This social support can modulate and balance stressgenerating contexts, and can cause demands to be experienced as stimuli, resulting in a lower "cost of accomplishment" of the task to be performed. (30) In this sense, as observed in the present study and in other investigations, (16, 18) healthcare workers with perception of low social support at work had a greater chance of mental suffering. (16, 18) In the pandemic scenario, with increased physical and emotional burden at work, combined with limited access to psychological support services, (28) the high odds of mental distress with a lower level of support from colleagues, is understandable. (8, 31) In this pandemic context, the Chinese recommendations include face-to-face support to deal with the psychological burden and the offer of telehealth services. (29) Therefore, in addition to improving working conditions, there are gains when organizing teams offer shelter, support, and collective and individual interventions to workers. (6, 31) Strategies can be developed to minimize fear of the risk of getting sick or infecting acquaintances, living with pain and death of patients and coworkers, and other issues that cause stress, such as the precarious working conditions illustrated in the results of this research. It is important that such actions be implemented in a preventive manner for all workers, and established as a permanent organizational policy of health and safety at work.

Considering that this is a pioneer study in the evaluation of workers' mental health and psychosocial stressors at work during the pandemic of COVID-19, with validated psychometric scales and statistical control techniques for confounding variables, there are limitations that should be taken into consideration when extrapolating its results. Notably, there was the participation of individuals with better access to technological tools and internet connectivity; despite the national scope, there is a mismatch between the demographic distribution of the country and the place of residence of participants; the greater research interest of people with signs and symptoms of mental distress and the impossibility of assessing losses; the use of selfreported questionnaires, which may be impacted by the cognitive repercussion of the participants' clinical condition; and the cross-sectional design of the study, which does not allow inferring causality among outcome and covariates.

Mental suffering was present in six out of ten healthcare workers, who participated in the study and were engaged in patient care during the COVID-19 pandemic. Individual factors influenced the increased chance of mental distress, such as female sex and age under 40 years.

Psychosocial characteristics of the job showed a strong association with the outcome, such as perceived high job strain at work, weekly workload of 60 or more hours, and low level of support from coworkers. Thus, there is an urgent need to map health services with these characteristics, to plan actions that promote mental health and prevent emotional distress at the various levels of care.

Considering the impact of the aspects of work context, and the content found in this group, a national policy for the evaluation and mitigation of psychosocial work risk is mandatory. The implementation of strategies that protect healthcare workers from stressful conditions may help to control the permanent negative repercussions on the workers' emotional wellbeing and quality of life.

Finally, additional longitudinal design studies with representative samples from each region of the country are suggested, to deepen the national discussion about the impact of work on workers' health, and to enable indicating effective interventions.
