RESUMEN
Several epidemiological studies suggested that frequency of tooth brushing may be associated with cardiovascular disease (CVD) risk, but the results remain inconclusive. Therefore, the aim of this study was to synthesize frequency of tooth brushing and CVD risk using meta-analysis. Science Direct, PubMed, CINAHL, and OVID were searched through October 15, 2022. The random-effects model was used to quantitatively assess the combined risk estimation. In addition, we performed the sensitivity analysis to evaluate the robustness of the study results by excluding the included studies one by one. A total of 9 cohort studies containing 10 reports with 803,019 individuals were included in the meta-analysis. Pooled results showed that compared with the lowest brushing frequency, the highest brushing frequency (relative risk = 0.85, 95% confidence interval: 0.80-0.90) significantly reduced the risk of cardiovascular disease. There was moderate heterogeneity among included studies (P = .002, I2 = 65.4%). The exclusion of any one study did not materially change the combined risk estimates. Our meta-analysis supported the hypothesis that higher frequency of tooth brushing can reduce the risk of CVD, which may have important implications for conducting research on the prevention strategies of CVD.
RESUMEN
BACKGROUND: Previous studies have suggested that ambient temperature is associated with the morbidity and mortality of stroke although results among these investigations remained unclear. Therefore, the purpose of present meta-analysis was to summarize the evidence of the relationship between ambient temperature and stroke morbidity and mortality. METHODS: A systematic search of the PubMed, Embase, and Web of Science databases was from inception to April 13, 2022. The pooled estimates for heat ambient temperature and cold ambient temperature, which were defined as comparison between extreme hot or cold conditions and the reference or threshold temperature, were calculated utilizing a random-effects model. A total of 20 studies were included in the meta-analysis. RESULTS: The pooled estimated show that the heat ambient temperature was significant associated with 10% (relative risk [RR], 1.10; 95% confidence interval [95%CI]: 1.02-1.18) and 9% (RR, 1.09; 95%CI: 1.02-1.17) increase in the risk of stroke morbidity and mortality, respectively. In addition, the pooled estimated show that the cold ambient temperature was significant associated with 33% (RR, 1.33; 95%CI: 1.17-1.51) and 18% (RR, 1.18; 95%CI: 1.06-1.31) increase in the risk of stroke morbidity and mortality, respectively. CONCLUSION: Integrated epidemiological evidence supports the hypothesis that both heat and cold ambient temperature have positive association with the risk of stroke morbidity and mortality. Targeted measures should be promoted in public health to reduce this risk.

BACKGROUND: Turnover has significant impact on nursing management and nursing safety. Nurses working in the Emergency Department are especially vulnerable to high turnover intention because of their increased risk of work-family conflict associated with the work characteristics. OBJECTIVE: This study aimed to investigate the effects of work-family conflict on emergency nurses' turnover intention and the role of positive and negative affect between work-family conflict and turnover intention. METHODS: A cross-sectional study. Data were collected from 17582 nurses working in emergency department in China. We employed a standardized questionnaire to collect sociodemographic information and target work-family conflict, affect and turnover intention. Mediation analyses were performed for the data analyses. RESULTS: On turnover intention, work-family conflict exerted both direct effect and indirect effect. The results also indicated that positive and negative affect partially mediated the effect of work-family conflict on turnover intention, and that 35.7% of this effect could be explained by mediating effects totally. CONCLUSIONS: The findings highlight positive and negative affect concern during the process of nursing management and nursing managers should take active measures to reduce negative affect and improve positive affect in order to reduce turnover intention and maintain the stability of the emergency nursing workforce.

BACKGROUND: In the context of the Corona Virus Disease 2019 (COVID-19) pandemic, research on personal-job fit and physical and mental health was inadequate. We aimed to explore the relationship between personal-job fit and physical and mental health among medical staff during the two years after COVID-19 pandemic and verify emotional labor and burnout as mediators. METHODS: A total of 2868 medical staff from two general hospitals, were included from July 3 to July 27, 2022, in Wuhan, China. SPSS was used for statistical description, and AMOS was used for structural equation modeling (SEM) to analyze the mediating effect of emotional labor and burnout. RESULTS: In the SEM, the total effect of personal-job fit on physical and mental health was significant (ß = 0.855, 95 % CI: 0.748-0.972). The mediating effect of surface acting between personal-job fit and physical and mental health was significant (ß = 0.078, 95 % CI: 0.053-0.110). The mediating effect of burnout was significant (ß = 0.220, 95 % CI: 0.175-0.274), but the mediating effect of deep acting was not significant (ß = 0.006, 95 % CI: -0.013-0.025). The chain mediating effect of surface acting or deep acting and burnout between personal-job fit and physical and mental health was significant (ß = 0.082, 95 % CI: 0.059-0.108; ß = 0.049, 95 % CI: 0.038-0.063). LIMITATIONS: Owing to the cross-sectional study, causal relationship, and direction of effects among variables could not be determined. CONCLUSIONS: Personal-job fit has significant direct and indirect effects on physical and mental health. Monitoring and intervening in personal-job fit, emotional labor, and burnout might be effective ways to promoting physical and mental health among medical staff during the COVID-19 pandemic.

BACKGROUND: Obesity is an established risk factor for cardiometabolic disease. Different measurements of obesity with cardiometabolic disease have been compared in recent studies in Western countries. However, obesity-related criteria for the Chinese population differ from the standard World Health Organization guidelines, and similar research in Chinese adults is limited. MEASURES: Data were obtained from a comprehensive intervention project involving a community population with cardiovascular and cerebrovascular risk factors in Shenzhen in 2015. A total of 4,000 participants (1,605 men and 2,395 women) with a mean age of 56.01±9.78 years were included in this study. Categorical data are reported as percentages, and continuous data are reported as mean ± standard deviation. Logistic regression analyses were conducted to examine the associations of body mass index (BMI), waist circumference (WC), and neck circumference (NC) with hypertension, diabetes, and dyslipidemia among Chinese adults. RESULTS: The participants had a mean BMI of 24.25±3.33 kg/m2, mean NC of 33.59±4.16 cm, and mean WC of 82.44±9.84 cm (men: 85.46±9.10 cm, women: 80.40±9.81 cm). Blood pressure, plasma glucose, and lipid levels in the BMI, WC, and NC groups were statistically significant (p < 0.05). BMI, WC, and NC were positively correlated with systolic blood pressure, diastolic blood pressure, fasting plasma glucose, total cholesterol, and triglyceride and negatively correlated with low-density lipoprotein cholesterol (p < 0.05), while the risk of hypertension, diabetes, and dyslipidemia increased with an increase in BMI, WC, and NC (p < 0.05). One SD of BMI, WC, and NC resulted in an increase of 41%, 22%, and 31% risk of hypertension; 45%, 34%, and 47% risk of diabetes; and 37%, 32%, and 23% risk of dyslipidemia, respectively. CONCLUSIONS: Compared to BMI and NC, WC was more strongly associated with cardiometabolic diseases in Chinese adults.

OBJECTIVES: This study investigated the effects of effort-reward imbalance (ERI) on emergency nurses' turnover intention and the role of depressive symptoms between ERI and turnover intention. BACKGROUND: Turnover intention is crucial for clinical practice due to its relationship with turnover behaviour and destructive effect on stability of nursing staff. The ERI is a mainstream model to explain job stress, which seems to be one of the key variables, but the direct evidence is not adequate. In addition, there have been only a few studies looking into the complexity of the relationship between ERI and turnover intention, and more research is needed. METHODS: This is a cross-sectional study conducted from July to August 2018, and the Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) guidelines were followed. We employed a standardised questionnaire to collect sociodemographic information and target turnover intention. Hierarchical multiple logistic regression and mediation analyses were performed for the data analyses. RESULTS: This study included responses from 17,582 emergency nurses in China. On turnover intention, ERI exerted both direct effect and indirect mediating effect. The results also indicate that depressive symptoms partially mediated the effect of ERI on turnover intention, and that 27.4% of this effect can be explained by mediating effects. CONCLUSIONS: To improve the turnover intention, it is necessary to consider reducing ERI and depressive symptoms of emergency nurses as powerful measures not to be ignored. RELEVANCE TO CLINICAL PRACTICE: This study provides important insights regarding how nursing administrators should better reduce the workload of caregivers and improve depressive symptoms to avoid turnover intention.

BACKGROUND: Evidence on the relationship between burnout and post-traumatic stress disorder (PTSD) is limited. We aimed to evaluate the association between burnout and PTSD symptoms among medical staff two years after the coronavirus disease 2019 (COVID-19) pandemic in Wuhan, China, and explore the mediating roles of social support and psychological resilience. METHODS: A multicenter survey was conducted online from January to March 2022 among healthcare professionals from six general hospitals. Hierarchical linear regression was used to detect the predictors of PTSD symptoms. Structural equation modeling (SEM) was used to analyze the pathways from burnout to PTSD symptoms. RESULTS: Hierarchical linear regression showed that burnout, social support, and psychological resilience were significant predictors of PTSD symptoms among medical staff. In the SEM, the standardized total effect of burnout on PTSD symptoms was 0.336(bias-corrected 95 % confidence interval [0.303, 0.367], P < 0.001). Social support and psychological resilience partially mediated the relationship between burnout and PTSD symptoms (indirect effects accounted for 22.3 % of the total effect). LIMITATIONS: Owing to the cross-sectional design, only clues to causal explanations can be provided. CONCLUSIONS: Burnout has significant direct and indirect effects on PTSD symptoms. Furthermore, social support and psychological resilience might be effective ways to reduce the impact of burnout on PTSD symptoms in medical staff after a major public health outbreak.

BACKGROUND: In December 2019, coronavirus disease (COVID-19) was first reported in Wuhan, China, and has had a negative psychological impact on the medical staff. However, the long-term psychological effects of COVID-19 were still unclear. We aimed to assess the posttraumatic stress disorder (PTSD) and depression among medical staff 2 years after COVID-19 pandemic in Wuhan, China. METHODS: We conducted a multicenter study in five general hospitals in Wuhan, China. PTSD was assessed using the PTSD Checklist-5. Depression was measured by the Center for Epidemiologic Studies Depression Scale. Multivariate adjusted logistic regression models were used to evaluate the association among demographic variables, depressive indicators, and PTSD. RESULTS: In a sample of 1795 medical staff, 295 (16.40%) participants reported PTSD and 329 (18.30%) reported depression. After multivariate adjusted logistic regression analyses, participants involved in COVID-19 clinical work, unsafe working environment, poor doctor-patient relationship, unhealth status, work dissatisfaction, and low family support were at a high risk for PTSD and depression 2 years after the outbreak of COVID-19 pandemic. CONCLUSIONS: Although it has been more than 2 years after the COVID-19 pandemic outbreak, the mental health of medical staff remains a concern. In particular, medical staff involved in the clinical care of COVID-19 patients showed a higher risk of PTSD and depression 2 years after the COVID-19 pandemic. This study may provide some useful suggestions for psychological interventions for medical staff.

Objective: Systemic lupus erythematosus (SLE) is a chronic and complex autoimmune disease characterized by multiple autoantibodies, resulting in multiple organ and tissue damages. These pathogenic autoantibodies produced by B cells are closely correlated with follicular helper T (Tfh) cell subsets that play a fundamental role in the pathogenesis of SLE. The aim of the present study was to study the phenotype and role of circulating Tfh (cTfh) cell subsets and associated B cell subpopulations in active and inactive SLE patients. Methods: Thirty SLE outpatients and 24 healthy controls (HCs) were enrolled in this study. The frequency of cTfh cell and B cell subsets in peripheral blood mononuclear cells (PBMCs) and the plasma levels of eight cytokines were determined by flow cytometry, and plasma IL-21 levels were measured by ELISA. Meanwhile, we used MRL/lpr mice as the model of SLE to research the alterations of Tfh cells in the thymus and spleen of mice. Results: Frequencies of CD4+CXCR5+CD45RA-effector cTfh cells, PD1+cTfh, PD1+ICOS+cTfh, PD1+cTfh1, PD1+cTfh2, PD1+cTfh17, and PD1+ICOS+cTfh1 cells as well as plasmablasts showed significant differences among HC, active and inactive SLE patients. Moreover, cytokines typically associated with cTfh cells, including IL-6 and IL-21, were elevated in active SLE patients compared to inactive SLE patients and HCs. Additionally, a positive correlation was observed between PD1+ICOS+ cTfh or PD1+ICOS+ cTfh1 cell frequencies and plasmablasts or IL-21 levels, as well as between plasmablasts. We also found PD1+ICOS+ Tfh cells expansion in both thymus and spleen of MRL/lpr mice, accompanied by increased frequencies in B cells and plasmablasts, meanwhile, cTfh1which expressing IFN-γ was increased in the peripheral blood of MRL/lpr mice. Conclusion: Tfh cell subsets and plasmablasts may play a fundamental role in the pathogenesis of SLE and may provide potential targets for therapeutic interventions for SLE.

BACKGROUND AND AIMS: Noise exposure is a major public health challenge with important implications for cardiovascular health. However, the association between noise exposure and stroke risk remains controversial. Therefore, we aimed to evaluate the role of noise exposure on stroke incidence and mortality by conducting a dose-response meta-analysis of cohort studies. METHODS: The relevant publications were retrieved via PubMed, Embase, Web of Science, and Scopus up to June 26, 2022. The potential linear and curve relationship between noise and stroke were fitted using the generalized least squares method and restricted cubic spline. We estimated the pooled relative risk (RR) with 95% confidence interval (CI) by random-effect models. The Grading of Recommendations Assessment Development and Evaluation (GRADE) approach was used to evaluate the strength of the results. RESULTS: In total, 21 cohort studies with 16,075,204 participants and 311,878 cases were included in the analysis. The risk of stroke incidence increased up to 4% (95% CI:1.02-1.06) and stroke mortality increased up to 3% (95% CI:1.00-1.07), every 10 dB(A) increment in noise exposure. Moreover, each 10 dB(A) increment in noise exposure was associated with a 4% (95% CI:1.01-1.07) increase in ischemic stroke and a 2% (95% CI:1.00-1.04) increase in hemorrhagic stroke. According to GRADE criteria, the evidence level in this study was rated as moderate. CONCLUSIONS: The current findings provide further evidence of a dose-response relationship between exposure to noise and the risk of stroke incidence and mortality. Additionally, we update and fill a knowledge gap that the statistically significant increase in stroke incidence when noise decibels are >65 dB(A).

BACKGROUND: The high morbidity, high mortality and low survival rate of cardiac arrest (CA) cause a heavy global burden. We aimed to analyze the changes in scientific output related to CA over the past two decades. METHODS: We analyzed the scientific output related to CA from 2000 to 2020 via the Web of Science. The data were analyzed using CiteSpace software. RESULTS: In total, 28,312 articles relating to CA were identified in the Web of Science. The volume of scientific research output in the field of global CA research was mainly distributed in the Americas, Europe and Asia, covering a wide range. Of the 28,312 articles, the research content of the highly cited literature mainly focused on CA, mild hypothermia treatment, and prognosis of CA patients. CONCLUSION: Various scientific methods were applied to reveal scientific productivity, collaboration, and research hotspots in the CA research field. Cardiopulmonary resuscitation (CPR), extracorporeal membrane oxygenation (ECMO), survival and target temperature management are research hotspots. Future research on CA will continue to focus on its treatment and prognosis to improve the survival rate of CA patients.
RESUMEN
Objectives: Wuhan is the city where coronavirus disease (COVID-19) was first reported and developed into a pandemic. However, the impact of the prolonged COVID-19 pandemic on medical staff burnout remains limited. We aimed to identify the prevalence and major determinants of burnout among medical staff 1 year after the beginning of the COVID-19 pandemic in Wuhan, China. Materials and Methods: A total of 1,602 medical staff from three hospitals in Wuhan, China, were included from November 1-28, 2021. Chi-square tests were conducted to compare the prevalence of burnout across groups based on sociodemographic and professional characteristics. A multivariate analysis was performed using a forward stepwise logistic regression model. Results: Approximately 37.39% of the medical staff experienced burnout 1 year after COVID-19 pandemic. Emotional exhaustion (EE) was the most common symptom of burnout, with 1,422 (88.76%) participants reporting a severe EE. Burnout was associated with insufficient social support and "neutral" or "dissatisfied" patient-physician relationships. Respondents who participated in the care of COVID-19 patients had a higher risk of burnout symptoms than those who did not participate. In particular, mental resilience was negatively associated with burnout among the medical staff. Conclusion: Nearly two-fifths of the participants had symptoms of burnout, with reduced personal accomplishment being the predominant symptom 1 year after COVID-19. Healthcare organizations should regularly measure and monitor burnout among the medical staff. In addition, creating positive work environments and improving the mental resilience of medical staff may be effective ways to reduce burnout.
RESUMEN
Objectives: This study aimed to evaluate the prevalence of anxiety among university teachers 1 year after the onset of the coronavirus disease 2019 (COVID-19) pandemic and provide empirical evidence of psychological intervention. Methods: A multicenter study was conducted to examine the prevalence of anxiety among 10,302 teachers in 21 Chinese universities from February 12 to April 23, 2021. The generalized Anxiety Disorder 7-item Scale (GAD-7) was used to assess symptoms of anxiety. Multivariate logistic regression models were used to analyze the relationship between potential influence and anxiety symptoms. Results: The overall prevalence of anxiety was 40.0% 1 year after the onset of the COVID-19 pandemic, which was found to be higher in women than in men (41.32% vs. 38.22%; p < 0.0001). The multivariate logistic regression showed that being the female (OR = 1.207; 95%CI: 1.103-1.318), age ≥60 years (OR = 2.004; 95%CI: 1.128-3.560), being married (OR = 1.319; 95%CI: 1.150-1.513), and poor family economic status (OR = 1.580; 95%CI: 1.321-1.891) were significantly associated with anxiety. Participants with moderate, slight, or no impact of COVID-19 on life (OR for moderate, 0.557; 95%CI, 0.508-0.611; OR for slight/no, 0.377; 95%CI, 0.323-0.439) showed a reduced risk of anxiety compared to those who reported a significant effect. Conclusions: Symptoms of anxiety were found in about two-fifths of Chinese university teachers 1 year after the outbreak of the COVID-19 pandemic. Our findings suggest that the government should improve the dynamic tracking of mental health and adopt long-term intervention strategies.
RESUMEN
The strength and shape of the dose-response relationship between different types of noise and myocardial infarction (MI) remain unclear. Therefore, we aimed to summarize the evidence of the association between various types of noise and MI incidence and mortality through a dose-response meta-analysis. We performed a systematic search of the PubMed, Embase, and Web of Science databases up to December 19, 2021. The generalized least-squares method and restricted cubic splines were used to assess the potential linear and nonlinear dose-response relationships between noise exposure and the risk of MI events. Twenty observational studies with 34 reports met the eligibility criteria. In the linear models, the pooled relative risk and corresponding 95% confidence interval (CI) for MI incidence was 1.04 (95% CI: 1.02 - 1.05), and the MI mortality was 1.02 (95% CI: 1.02 - 1.03) for each 10 dB(A) increase in noise exposure. In addition, we observed an approximately J-shaped dose-response relationship between noise and MI mortality (Pnonlinearity = 0.0037), whereas the threshold for the statistical impact of noise on MI mortality may be 42 dB(A). Our findings support the notion that various types of noise exposure have a positive dose-response relationship with the risk of MI incidence and mortality.

It is unclear whether the frequency of tooth brushing affects the risk of hypertension; thus, we conducted the first meta-analysis to focus on this topic. In this meta-analysis, we systematically searched the PubMed, Scopus, and Web of Science databases from their inception to October 2021 to identify eligible studies, while reference lists from retrieved review paper were also reviewed. We then conducted a meta-analysis of the highest compared with the lowest tooth brushing frequency, along with a dose-response meta-analysis, to explore this association. Subgroup and sensitivity analyses were conducted to identify the sources of heterogeneity. Publication bias was evaluated using Begg's and Egger's tests. We found eight relevant studies, three cohort and five cross-sectional, involving a total of 274 124 patients. Compared to the highest tooth brushing frequency, the lowest increased the risk of hypertension by 84.0% (OR 1.84; 95% CI, 1.44-2.35). Furthermore, a nonlinear dose-response relationship was observed (P < .05). The exclusion of any studies did not significantly alter the combined risk estimate, and no publication bias was detected. In conclusions, we report that epidemiological evidence supports the hypothesis that a lower frequency of tooth brushing is significantly associated with a higher risk of hypertension. Preventive interventions, such as adopting a good oral health routine, should be encouraged to maintain good general health.

BACKGROUND: Although breastfeeding is one of the top priorities for public health in China, the rate of breastfeeding is still low and a large number of women do not initiate breastfeeding due to various reasons. Hence, this study aimed to understand the decision-making of non-initiation and reveal the underlying reasons in order to protect, support, and promote breastfeeding. METHODS: In-depth, exploratory interviews were carried out with 13 new mothers who did not initiate breastfeeding. The collected data were analyzed by inductive content analysis. RESULTS: Although mothers generally understood the protective effects of breastfeeding, they believed that formula milk is a good alternative to human milk and even better in some aspects. Five core themes related to non-initiation decision-making emerged: (1) expected breastfeeding stress; (2) maladjustment to the maternal role; (3) concerns about physiological issues; (4) the lack of knowledge about the risks of artificial feeding; (5) belief that it is better not to initiate than to interrupt. CONCLUSIONS: The environment for mothers to breastfeed in China is not supportive enough, and the medical staff and families should be held responsible for the non-initiation of breastfeeding. More professionals are needed to support mothers to solve their problems and breastfeeding education should be further expanded.

BACKGROUND AND AIM: Considering the inconsistent findings of research into the associations between serum levels of liver enzymes (alanine aminotransferase [ALT], aspartate aminotransferase [AST], and gamma-glutamyltransferase [GGT]) and mortality among elderly people, we aimed to investigate the associations of ALT, AST, GGT, and De-Ritis ratio (DRR, defined as AST/ALT) and all-cause or cause-specific mortality among the US elderly people using National Health and Nutrition Examination Surveys data. METHODS: We included 6415 elderly participants (≥ 65 years). Exclusion criteria included positive test for hepatitis B virus, hepatitis C virus, and human immunodeficiency virus infection at baseline. Multivariable-adjusted Cox regression models calculating hazard ratios (HR) and 95% confidence intervals were developed for each of the liver enzyme measures. RESULTS: All-cause cumulative mortality was 33.8%, of which 23.8% were cardiovascular disease (CVD) deaths, 15.6% were cancer deaths, and 60.6% were other cause deaths. Adjusted Cox models found increased all-cause mortality risk for low ALT (HR: 1.70), low AST (HR: 1.13), high GGT (HR: 1.25), and high DRR (HR: 1.68). Low ALT and high DRR predicted CVD mortality. Low ALT (HR: 1.91), low AST (HR: 1.16), high GGT (HR: 1.40), and high DRR (HR: 1.76) predicted other cause mortality. CONCLUSIONS: Low ALT and high DRR were associated with increased CVD and cancer mortality. All serum liver enzyme measures were associated with all-cause mortality and other cause mortality in the US elderly population. Further studies may validate these findings in other elderly populations.

PURPOSE: Although a significant proportion of type 2 diabetes mellitus (T2DM) cases arose from normal-weight individuals, studies on indicators of T2DM in normal-weight people are limited. Accordingly, this study aims to investigate the predictive value of obesity indices and triglyceride glucose-related parameters (TyG-related parameters) in T2DM among normal-weight Chinese elderly. METHODS: A total of 24,215 normal-weight Chinese elderly (age ≥ 60 years) [body mass index-BMI (18.5-23.9 kg/m2)] were included. Obesity indices and triglyceride glucose-related parameters (TyG-related parameters) included waist circumference (WC), waist-to-height ratio (WHtR), visceral adiposity index (VAI), lipid accumulation product (LAP), and TyG-related parameters (TyG, TyG-BMI, TyG-WC, and TyG-WHtR). Multivariate logistic regression analysis was performed to examine the associations between obesity- and TyG-related indices and T2DM. The areas under the curve (AUC) of the receiver-operating characteristic (ROC) curve analyses were used to evaluate and compare the predictive value of the different indices. RESULTS: The prevalence of T2DM was 14.2% in normal-weight individuals. Among the indices, TyG was significantly associated with T2DM among men and women, respectively, (adjusted odds ratio-aOR per SD 3.46; 95% CI 3.23-3.71) and (aOR per SD 3.64; 95% CI 3.43-3.86). Compared with other indices, TyG had the highest AUC value for T2DM in men (AUC: 0.818, 95% CI 0.810-0.825) and women (AUC: 0.824, 95% CI 0.814-0.833). CONCLUSIONS: TyG is an effective marker and outperforms other indices when predicting T2DM in the normal-weight Chinese elderly population. LEVEL OF EVIDENCE: Level V: Opinions of authorities, based on descriptive studies, narrative reviews, clinical experience, or reports of expert committees.

Coronavirus disease 2019 (COVID-19) has significantly caused socioeconomic impacts. However, little is known about the psychological effect of COVID-19 on home-quarantined nursing students. The present study aimed to identify the prevalence and major determinants of anxiety, depression and post-traumatic stress symptoms (PTSS) in Chinese nursing students during the COVID-19 pandemic quarantine period. An online survey was conducted on a sample of 6,348 home-quarantined nursing students. Mental health status was assessed by the Generalized Anxiety Disorder 7-Item Scale (GAD-7), the Patient Health Questionnaire 9-Item Scale (PHQ-9) and the Post Traumatic Stress Disorder Check List-Civilian version (PCL-C), respectively. Logistic regression analyses were performed to identify risk factors of anxiety, depression and PTSS.
