It is extremely important to understand the prevalence and influencing factors of anxiety and depression symptoms in first-line anti-epidemic medical staff and their coping styles for these negative emotions. METHODS: A cross-sectional survey was conducted in Gansu (China), with a questionnaire packet which consisted of the self-rating anxiety scale (SAS), self-rating depression scale (SDS), and the simplified coping style questionnaire (SCSQ). A total of 79 doctors and 86 nurses participated in the survey. Correlation analysis was performed to explore the relationship between SAS, SDS, and SCSQ score. A linear regression model was used to determine the influencing factors for anxiety or depression symptoms. RESULTS: The prevalence rates of anxiety and depression symptoms among doctors was 11.4% and 45.6%, respectively. History of depression or anxiety (T=-2.644, p= 0.010, 95%CI: -10.514~-1.481) was shown to be a risk factor for anxiety symptoms in doctors, while being male (T=2.970, p=0.004, 95%CI: 2.667~13.521) was a protective factor for depression. The prevalence rate of anxiety and depression symptoms among nurses was 27.9% and 43.0%, respectively. History of depression or anxiety was a common risk factor for anxiety symptoms (T=-3.635, p=0.000, 95%CI: -16.360~-4.789) and depression symptoms (T=-2.835, p=0.005, 95%CI:-18.238~-3.254) in nurses. The results of partial correlation analysis (controlled for gender and history of depression or anxiety) indicated that the total score of positive coping was negatively correlated with the total score of anxiety (r=-0.182, p=0.002) and depression (r=-0.253, p=0.001). CONCLUSIONS: The first-line anti-epidemic medical staff have high anxiety and depression symptoms and adopting positive coping styles will help to improve their negative emotions. Since mid-December of 2019, coronavirus disease 2019 (COVID-19) has been spreading from China (Wuhan) to 26 countries worldwide (1) . As of February 24 th , 41600 medical staff across the country have been fighting in the front line of the anti-epidemic campaign. Of these medical staff, 3387 of them were infected with the novel coronavirus pneumonia, accounting for 4% of all confirmed cases, while 22 were killed and accounted for 0.8% of the deaths. The front-line medical staff will not only bear the work pressure of overload, but also face the huge risk of infection (2) . Stress represents the main environmental risk factor for psychiatric illnesses, and in a long-term stress state, people can be more prone to depression or other mental disease (3) , which will also increase the risk of infection (4) (5) (6) . Therefore, it is necessary to investigate the psychological state of the first-line anti-epidemic medical staff and give them necessary psychological interventions if they have anxiety or depression. This cross-sectional study was conducted between February 1, 2020 and February 29, 2020. The research objects were the first line medical staff in the designated hospitals and fever clinics of novel coronavirus pneumonia in Gansu Province. The inclusion criteria were as follows: 1) 18 years or older; 2) doctor or nurse; 3) first-line to COVID-19; 4) without serious mental illness, such as schizophrenia or an intellectual disability; 5) without physical disease affecting anxiety or depression, such as hypothyroidism or coronary heart disease; and 6) willing to be investigated. Exclusion criteria were as follows: 1) less than 18 years old, 2) non-frontline medical or administrative staff, 3) not in Gansu, 4) serious mental illness or a combination of disorders that may affect anxiety or depression, and 5) refused to be investigated. Finally, 165 front-line medical staff working in the Wuhan isolation ward were enrolled in the study. Ethical approval was issued by the Ethics Committee of the Second Clinical Medical College of Lanzhou University, and all the participants had signed an informed consent before the study was initiated. By using the self-designed questionnaire, we have obtained the general demographic information of the respondents, including gender, age, marriage, occupation, education level, specialty, level of worry, and level of expectation. The self-rating anxiety scale (SAS) (7) and self-rating depression scale (SDS) (8) were used to assess anxiety and depression symptoms of medical staff respectively. Both SAS and SDS are 20-item Likert and norm-referenced scales, in which items tap physiological and psychological symptoms and are rated by participants according to how each applied to them within the past week, using a 4-point scale ranging from 1 (none, or a little of the time) to 4 (most, or all of the time) (9) . The choice of SAS items is based on diagnostic criteria listed in the major American psychiatry literature, whereas the SDS taps depressive symptoms based on factor analytic studies of depression symptoms (9) . The Zung Self-Rating Anxiety/Depression Scale (SAS/SDS) has been widely applied in clinical institutions and scientific research, showing convincing results and a remarkable degree of consensus among clinicians (10) . According to the conclusion of other studies (11), we also utilized the standard score of 50 as the critical value to divide depression or anxiety in the present study. The Simplified Coping Style Questionnaire (SCSQ) (12) is a 20-item self-report scale that includes two dimensions. The first entry consists of 1-12 items and reflects the traits of passive coping and active coping (8-item). The second entry consists of 13-20 questions, reflecting the traits of passive coping. This instrument has been commonly used in China and has proven to be highly reliable and valid (13) . In the current study, we used the Electronic "Questionnaire Star" Questionnaire as the survey tool, and information was collected through friend circle forwarding and WeChat group promotion. "Questionnaire Star" is a professional online survey platform, which can be used for questionnaire surveys, evaluation, voting, and other purposes. Compared with traditional survey methods, "Questionnaire Star" has the obvious advantages of being fast, low cost, easy to learn, and easy to use (14) . The categorical variables were expressed as the frequency (%), while the continuous variables were presented as mean± SD. A single sample Kolmogorov-Smirnov test was used to test whether the data conform to normal distribution. Chi square test was used to compare categorical variables, while independent sample t-test and Mann-whitney U test were respectively used to compare the continuous variables with and without normal distribution. The prevalence of anxiety and depression symptoms was calculated by splitting the total number of cases diagnosed by the total number of participants. The influence factors of anxiety or depression were analyzed by linear regression analysis. Partial correlation analysis was used to analyze the correlation between SCSQ and SDS/SAS. The statistical analysis was performed by using SPSS version 22.0 and a p-value < 0.05 was regarded as significant. Through the online survey from Questionnaire Stars, we finally received 165 qualified questionnaires, and the recovery rate of the questionnaire was 100%. The average age of the respondents was 34.16 ± 8.06 (years), the average length of employment was 11.35 ± 8.60 (years), the average working day on the fever clinic or isolation ward was 15.65 ± 46.63 (days), the average anxiety score was 42.79 ± 8.50, and the average depression score was 46.94 ± 11.60. Tables 1 and 2 show the results. With 50 points as the critical value (both for SAS and SDS), nine people were considered to have anxiety symptoms, with a prevalence of 11.4% (9/79), and 36 people were considered to have depression symptoms, with a prevalence of 45.6% (36/79). There were statistical differences (p < 0.05) in the total score of negative responses and a history of anxiety or depression between the anxiety group and non -anxiety group, while there were statistical differences (p < 0.05) in gender between the depression group and non -depression group. Table 3 presents the results. Then, by using linear regression analysis, we found that history of depression or anxiety (T=-2.644, p= 0.010, 95%CI: -10.514~-1.481) was a risk factor for anxiety symptoms in doctors, while being male (T=2.970, p=0.004, 95%CI: 2.667~13.521) was a protective factor for depression. Table 4 lists the results. With 50 points as the critical value (both for SAS and SDS), 24 people were considered to have anxiety symptoms, with a prevalence of 27.9% (24/86), and 37 people were considered to Objects of concern Heavy workload, n(%) 12 ( have depression symptoms, with a prevalence of 43.0% (37/86). There were statistical differences (p < 0.05) in the history of anxiety or depression between the anxiety group and non -anxiety group, while there were statistical differences (p < 0.05) in the total scores of active response, history of anxiety or depression, and specialty between the depression group and non -depression group. Table 5 presents the results. Then, by using linear regression analysis, we found that a history of depression or anxiety was a common risk factor for anxiety symptoms (T=-3.635, p=0.000, 95%CI: -16.360~-4.789) and depression symptoms (T=-2.835, p=0.005, 95%CI:-18.238~-3.254) in nurses. Table 6 lists the results. The results of partial correlation analysis (controlled for gender and history of depression or anxiety) indicated that the total score of positive coping was negatively correlated with the total score of anxiety (r=-0.182, p=0.002) and depression (r=-0.253, p=0.001) In the current study, we investigated the prevalence and influencing factors of anxiety and depression symptoms in the first-line medical staff fighting against novel coronavirus pneumonia in Gansu, and came to some interesting conclusions: 1) the prevalence rate of anxiety and depression symptoms among doctors was 11.4% and 45.6%, respectively; 2) the prevalence rate of anxiety and depression symptoms among nurses was 27.9% and 43.0%, respectively; 3) a history of depression or anxiety (T=-2.644, p= 0.010, 95%CI: -10.514~-1.481) was a risk factor for anxiety symptoms in doctors, while being male (T=2.970, p=0.004, 95%CI: 2.667~13.521) was a protective factor for depression; 4) a history of depression or anxiety was a common risk factor for anxiety symptoms (T=-3.635, p=0.000, 95%CI: -16.360~-4.789) and depression symptoms (T=-2.835, p=0.005, 95%CI:-18.238~-3.254) in nurses; 5) the results of partial correlation (controlled for gender and history of depression or anxiety) indicated that the total score of positive coping was negatively correlated with the total score of anxiety (r=-0.182, p=0.002) and depression (r=-0.253, p=0.001). Previous studies had suggested that the mental health status of medical staff was worse than in the general population (15, 16) . For example, Kerrien M et al. (17) found that 27% of junior doctors were suffering from depression, while 28.7% were suffering from anxiety. Paiva CE et al. (18) found that 12.3%of doctors had depression (HADS-D ≥ 11), and 19.4% had anxiety (HADS-A ≥ 11). A systematic review of 29 studies showed that the prevalence of anxiety and depression among students in medical schools in Europe, the UK, and elsewhere in the Englishspeaking world outside of North America was 7.7-65.5% and 6.0-66.5%, respectively (19) . Similarly, a cross-sectional survey showed that the prevalence of anxiety symptoms in nurses was 43.4% (20) . Another cross-sectional survey indicated that the prevalence rate of anxiety among female nurses was 41.1% (21) . Maharaj S et al. (22) found that the prevalence rates of depression and anxiety among Australian nurses were 32.4% and 41.2%, respectively. So, our conclusions were not consistent, and this difference might come from the use of different investigation tools. Interestingly, we found that the anxiety level (X 2 = 7.019. p=0.011) of nurses was significantly higher than that of doctors, but there was no difference in depression (X 2 = 0.108. p=0.756) between the two groups. So we need to pay more attention to nurses in order to relieve their anxiety. In the present study, we found that being male (T=2.970, p=0.004, 95%CI: 2.667~13.521) was a protective factor for depression in doctors. There is considerable discourse surrounding the disproportionate diagnosis of men with depression as compared to women, often times cited at a rate around 1:2 (23) . However, the view that depression rates are universally higher in women is challenged, as biological determinants, sex role changes, and social factors might also contribute to this difference (24) . What's more, meta-analyses of diagnoses and symptoms show that the gender difference peaks in adolescence but then will decline and remain stable in adulthood, and cross-national analyses also indicate that larger gender differences are found in nations with greater gender equity for major depression, but not depression symptoms (25) . But beyond that, a systematic review of nineteen studies indicates that the male gender is significantly associated with suicide in individuals with depression (26) . So, the relationship between gender and depressive symptoms needs to be verified by a large-scale longitudinal study. We also found that a history of anxiety or depression was a risk factor for anxiety symptoms in doctors, and a common risk factor for anxiety and depression symptoms in nurses. Osasona SO et al. (27) found that previous mental illness was significantly associated with anxiety, depression, or general psychiatric morbidity in a sample of inmates in a Nigerian prison. Ahmed A et al. (28) found that a history of depression and stress was associated with depressive and anxiety symptoms in a sample of 615 women in Saskatchewan from pregnancy to 5 years postpartum. Stafford L et al. (29) found that women with a psychiatric history and high neuroticism are at the greatest risk for future morbidity after adjusting for confounders, such as age, education, and living alone. Therefore, our conclusions are consistent. By using partial correlation analysis (controlled for gender and history of depression or anxiety), we finally found that a positive coping style was a protective factor for anxiety(r=-0.182, p=0.002) and depression (r=-0.253, p=0.001), suggesting that a positive coping style was helpful in resisting negative emotions. Mahmoud JS et al. (30) found that reducing maladaptive coping behaviors might have the most positive impact on reducing anxiety, depression, and stress in young adult college students. Wang Y et al. (31) found that perceived stress had some positive effects on psychological distress, and coping style might be a mediator in this relationship among Chinese physicians. In addition, Holz NE et al. (32) pointed out that stress exposure would increase rates of depression and anxiety in adults, particularly in females, and had been associated with maladaptive changes in the anterior cingulate cortex (ACC), while positive coping styles could help to increase the ACC volume. So our conclusions were consistent. We have to admit that our research has certain limitations. First, it was just a cross-sectional study that could not establish a causal link. Second, the sample size used was relatively small and therefore reduced the reliability of the study. Third, we used the selfassessment scale to evaluate the depression and anxiety symptoms of the medical staff, which might have a certain result deviation. The first-line anti-epidemic medical staff have high anxiety and depression symptoms, and adopting a positive coping style will help to improve their negative emotions.
