Public trust in general practitioners and its association with primary care contracts: a cross-sectional study of community residents in China.

OBJECTIVES: This study aimed to assess the level of public trust in general practitioners (GPs) and its association with primary care contract services (PCCS) in China. STUDY DESIGN: Cross-sectional study. METHODS: Between September and December 2021, 4158 residents across eastern, central, and western China completed a structured self-administered questionnaire. Trust was assessed using the Chinese version of Wake Forest Physician Trust Scale. Multivariable linear regression models were established to identify predictors of trust. The effect size of PCCS on trust was estimated by the average treatment effect for the treated (ATT) through propensity score matching. RESULTS: The study participants had a mean Wake Forest Physician Trust Scale score of 36.82 (standard deviation = 5.45). Enrollment with PCCS (ß = 0.14, P < 0.01), Han ethnicity (ß = 0.03, P < 0.05), lower educational attainment (ß = -0.06, P < 0.01), higher individual monthly income (ß = 0.03, P < 0.05), better self-rated health (ß = 0.04, P < 0.05), chronic conditions (ß = 0.07, P < 0.01), and higher familiarity with primary care services (ß = 0.12, P < 0.01) and PCCS (ß = 0.21, P < 0.01) were associated with higher trust in GPs. The ATT of PCCS exceeded 1 (P < 0.05). CONCLUSIONS: PCCS are associated with higher levels of trust in GPs. PCCS may become an effective tool to attract public trust in GPs, although the relationship between the two may be bi-directional.

Improved Generative Adversarial Network for Super-Resolution Reconstruction of Coal Photomicrographs.

Analyzing the photomicrographs of coal and conducting maceral analysis are essential steps in understanding the coal's characteristics, quality, and potential uses. However, due to limitations of equipment and technology, the obtained coal photomicrographs may have low resolution, failing to show clear details. In this study, we introduce a novel Generative Adversarial Network (GAN) to restore high-definition coal photomicrographs. Compared to traditional image restoration methods, the lightweight GAN-based network generates more explicit and realistic results. In particular, we employ the Wide Residual Block to eliminate the influence of artifacts and improve non-linear fitting ability. Moreover, we adopt a multi-scale attention block embedded in the generator network to capture long-range feature correlations across multiple scales. Experimental results on 468 photomicrographs demonstrate that the proposed method achieves a peak signal-to-noise ratio of 31.12 dB and a structural similarity index of 0.906, significantly higher than state-of-the-art super-resolution reconstruction approaches.

Prevalence and predictors of depression among emergency physicians: a national cross-sectional study.

BACKGROUND: Physicians' depression can damage their physical and mental health and can also lead to prescribing errors and reduced quality of health care. Emergency physicians are a potentially high-risk community, but there have been no large-sample studies on the prevalence and predictors of depression among this population. METHODS: A nationally representative cross-sectional survey of 15,243 emergency physicians was conducted in 31 provinces across China between July and September 2019. Multivariable logistic regression analysis was performed to identify predictors of depression. RESULTS: A total of 35.59% of emergency physicians suffered from depression. Emergency physicians who were male (OR=0.91) and older [>37 and ≤43 (OR=0.83) or >43 (OR=0.71)], had high (OR=0.63) or middle (OR=0.70) level income, and participated in physical inactivity (OR=0.85) were not more likely to suffer depression. Meanwhile, those who were unmarried (OR=1.13) and smokers (OR=1.12) had higher education levels [Bachelor's degree (OR=1.57) or Master's degree or higher (OR=1.82)], long work tenure [>6 and ≤11 (OR=1.15) or >11;11 (OR=1.19)], poorer health status [fair (OR=1.67) or poor (OR=3.79)] and sleep quality [fair (OR=2.23) or poor (OR=4.94)], a history of hypertension (OR=1.13) and coronary heart disease (OR=1.57) and experienced shift work (OR=1.91) and violence (OR=4.94)]. CONCLUSION: Nearly one third of emergency physicians in China suffered from depression. Targeted measures should be taken to reduce the prevalence of depression to avoid a decline in health care quality and adversely impact the supply of emergency medical services.

Prevalence and associated factors for workplace violence among general practitioners in China: a national cross-sectional study.

BACKGROUND: General practitioners (GPs) were at risk of violence in their everyday working lives. Workplace violence (WPV) among GPs is a global public health concern. This study aimed to investigate the prevalence and factors associated with WPV among GPs in China. METHODS: A cross-sectional study was conducted among 4376 GPs in eastern, central, and western China between March and May 2021 using a structured self-administered questionnaire. The multivariable stepwise logistic regression model was used to examine the factors associated with WPV among GPs in China. RESULTS: Among these respondents, 14.26% of them reported exposure to WPV in the past 12 months. GPs who were female, practised in a rural area, made home visits occasionally, worked in a fair or good practice environment or work environment, and had a fair or good relationship with patients were less likely to encounter any type of WPV. In addition, GPs who served patients over 20 per day and worked overtime occasionally or frequently were more likely to be exposed to WPV. The determinants of WPV varied in different types of WPV and sexes. CONCLUSIONS: The prevalence of WPV among GPs is low in China. Our findings could inform the measures to reduce the WPV among GPs.

Timeliness of information disclosure during the low transmission period of COVID-19: resident-level observational study in China.

BACKGROUND: Only when people feel they have received timely disclosure will they have sufficient incentive to implement community prevention and control measures. The timely and standardized information published by authorities as a response to the crisis can better inform the public and enable better preparations for the pandemic during the low transmission period of COVID-19; however, there is limited evidence of whether people consent that information is disclosed timely and influencing factors. METHODS: A cross-sectional survey was conducted in China from 4 to 26 February 2021. Convenient sampling strategy was adopted to recruit participators. Participants were asked to filled out the questions that assessed questionnaire on the residents' attitudes to information disclosure timely. A binary logistic regression analysis was performed to identify the risk factors affecting the residents' attitudes. RESULTS: A total of 2361 residents filled out the questionnaire. 1704 (72.17%) consented COVID-19 information has been disclosed timely. Furthermore, age (OR = 0.093, 95%CI = 0.043 ~ 0.201), gender (OR = 1.396, 95%CI = 1.085 ~ 1.797), place of residence (OR = 0.650, 95%CI = 0.525 ~ 0.804), employed status (OR = 2.757, 95%CI = 1.598 ~ 4.756), highest educational level (OR = 0.394, 95%CI = 0.176 ~ 0.880), region (OR = 0.561, 95%CI = 0.437 ~ 0.720) and impact on life by the COVID-19 (OR = 0.482, 95%CI = 0.270 ~ 0.861) were mainly factors associated with residents' attitudes. CONCLUSIONS: The aims of this study were to evaluate the residents attitudes to information disclosure timely during the low transmission period in China and to provide a scientific basis for effective information communication in future public health crises. Timely and effective efforts to disclose information need to been made during the low transmission period. Continued improvements to local authority reporting will contribute to more effective public communication and efficient public health research responses. The development of protocols and the standardization of epidemic message templates-as well as the use of uniform operating procedures to provide regular information updates-should be prioritized to ensure a coordinated national response.

Occupational stress and associated factors among general practitioners in China: a national cross-sectional study.

BACKGROUND: Occupational stress among general practitioners (GPs) is a public health concern. This study aimed to investigate the prevalence and factors associated with occupational stress among GPs in China. METHODS: A cross-sectional design was used. Data were collected from 3,236 GPs in eastern, central, and western China (response rate, 99.75%) between October 2017 and February 2018 using a structured self-administered questionnaire. An ordinal logistic regression model was used to identify the factors associated with occupational stress among GPs. RESULTS: Among these respondents, 313 (9.67%), 1,028 (31.77%), and 1,895 (58.56%) of GPs had a low, medium, and high level of occupational stress, respectively. GPs from central China, with temporary work contracts, without management responsibility, receiving a moderate level of income, and with moderate occupational development opportunities had a lower level of occupational stress. GPs with greater than 40 working hours per week and those who worked overtime occasionally or frequently had a higher level of occupational stress. CONCLUSIONS: The prevalence of occupational stress among GPs is high in China. Substantial regional variation in determinants of occupational stress among GPs was observed. These findings should inform the design of policies to reduce the occupational stress of GPs.

The global prevalence of sexual violence against pregnant women: a systematic review and meta-analysis.

When committed against pregnant women, sexual violence may have adverse health consequences for both the mother and the unborn child. To date, no studies have systematically summarized the global prevalence of sexual violence against pregnant women. We conducted a comprehensive search of PubMed, Embase and Web of Science from inception dates to January 2021 for studies reporting the prevalence of sexual violence against pregnant women. Prevalence was estimated using a random-effects meta-analysis. Heterogeneity was evaluated using the I2 statistic. Differences by study level characteristics were estimated through subgroup analysis and meta-regression. A total of 10 cross-sectional studies (a total of 8,439 participants) were included. The pooled proportion of sexual violence was 0.31 (95% CI: 0.22-0.40). Subgroup analyses showed higher prevalence of sexual violence against pregnant women in the 2010-2019 period (0.35, 95% CI0.15-7.53) and developing countries (0.32, 95% CI0.19-0.45). Almost one in three (31%) pregnant women around the world has been a victim of sexual violence in their lifetime. Sexual violence against pregnant women continues to be a major public health challenge. The global prevalence of sexual violence against pregnant women warrants the collective attention of the entire society.

Ultrafast discrete swept source based on dual chirped combs for microscopic imaging.

An inertial-free, ultrafast frequency comb source based on two chirped optical frequency combs (OFCs) is proposed and experimentally demonstrated. The high linearity frequency sweeping is realized by the Vernier effect between the two OFCs rather than any mechanical motion component, so that good stability and reliability are ensured and no recalibration or resampling process is required. Swept rate up to 1 MHz is realized while keeping a narrow instantaneous linewidth of 0.03 nm, thanks to the extra-cavity frequency sweeping method. The wavelength step is proportional to the swept rate (3.8 pm at 10 kHz), and can be tuned by changing the repetition rate difference between the two OFCs. This swept source is applied for high-speed wavelength encoded imaging and achieves 4.4-µm spatial resolution at a 329-kHz frame rate. Compared with the traditional time-stretch microscopy, the signal acquisition bandwidth decreased from 3.8 GHz to below 90 MHz to achieve the same spatial resolution. Furthermore, the exposure time for a specific wavelength is much longer due to the discrete sweeping feature, which is a benefit for higher sensitivity. This discrete swept source provided a promising low-cost option for high-speed biomedical imaging systems and high-accuracy spectroscopy.

Calibration-free time-stretch optical coherence tomography with large imaging depth.

We demonstrate a calibration-free time-stretch optical coherence tomography (TS-OCT), based on an optical higher order dispersion compensation scheme, which substitutes the digital calibration with optical dispersion compensation. As a result, the acquired raw data can directly perform the Fourier transform, and data processing time is greatly reduced by 82%, compared with the digital calibration. Moreover, because of the high-sensitivity and calibration-free characteristics, the high-order dispersion compensation-based TS-OCT can increase sensitivity roll-off by 2.6 times to 6.91 mm/dB and effective imaging depth by 14.2% to 16 mm. The in vivo biological tissue imaging has been demonstrated, with the single-shot A-scan rate approaching 19 MHz. This higher order dispersion compensation scheme could provide a promising solution for the TS-OCT system to realize 3D imaging in real time and enhanced imaging quality.

Ultrafast time-stretch microscopy based on dual-comb asynchronous optical sampling.

The ultrafast time-stretch microscopy based on a single-pixel detector has become a hotspot of the research, owing to its high sensitivity compared to those pixel sensors. However, gigahertz or tens of gigahertz acquisition bandwidth is required for this scheme, resulting in great expense for the whole imaging system and hindering its wide applications. In this Letter, a dual-comb asynchronous optical sampling is applied for the conventional time-stretch microscopy, whose ultrafast temporal axis is magnified by 9200 times. The acquisition bandwidth requirement is thus greatly relaxed, and 320 kHz bandwidth successfully resolves 2.3 µm spatial resolution with tens of kilohertz frame rate.

Analysis on the relationship between professional identity and turnover intention among general practitioners: The mediating role of job burnout.

OBJECTIVE: We aimed to understand the current situation and contributory factors associated with professional identity, turnover intention and job burnout among general practitioners (GPs) in eastern, central and western China. METHODS: A total of 3244 GPs from community health service institutions in 12 provinces of China were recruited, from October 2017 to February 2018. Demographic information such as sex, region and mode of employment was sought, and issues regarding job burnout, professional identity and turnover intention of GPs were measured with the corresponding scale, and softwares such as SPSS and AMOS were used. T-test, analysis of variance, and covariance matrix were used for analysis. RESULTS: The average total scores of job burnout, turnover intention and professional identity of GPs in China were 44.12, 15.07 and 51.23, respectively. The results of intermediary effect analysis showed that in the GPs group, there were differences in the distribution of the three indicators. Professional identity had a significant negative effect on job burnout (ß = -0.373), while job burnout had a significant positive effect on turnover intention (ß = 0.528), and job burnout had an indirect effect in the relationship between professional identity and turnover intention. Job burnout played an intermediary role in professional identity and turnover intention. CONCLUSIONS: The turnover intention of GPs in China has improved, but it is still at a high level. Job burnout plays an intermediary role between professional identity and turnover intention.

The impact of burnout on turnover intention among Chinese general practitioners: The mediating effect of job satisfaction and the moderating effect of professional identity.

BACKGROUND: Turnover among general practitioners (GPs) has become a significant public health concern worldwide. AIMS: This study aimed to investigate the interrelationships between job satisfaction, professional identity, burnout, and turnover intention among GPs in China and to assess the mediating effect of job satisfaction on the association between burnout and turnover intention and the moderating effect of professional identity on the association between burnout and job satisfaction. METHOD: A cross-sectional study was conducted to collect data from 3,236 GPs in eastern, central, and western China between October 2017 and February 2018 using a self-administered questionnaire. Pearson's correlation analysis and hierarchical regression were used to identify the relationships between job satisfaction, professional identity, burnout, and turnover intention among Chinese GPs. RESULTS: Among these respondents, 65.02% reported a medium or high level of emotional exhaustion (EE), 35.38% reported a moderate or high level of depersonalization (DP), and 62.05% reported reduced personal achievement (PA). Overall, 71.08% of GPs expressed a relatively high intention to seek another position (turnover intention). We found all 3 dimensions of burnout contributed to job dissatisfaction while turnover intention arising from burnout was associated with EE and DP. Job satisfaction had a direct negative impact on turnover intention and partially mediated the impact of EE and DP on turnover intention. Professional identity played a partial moderated role between EE and job satisfaction. CONCLUSIONS: The prevalence of burnout and turnover intention among GPs is high in China. The effect of EE and DP on turnover intention is mediated by job satisfaction, and the effect of EE on job satisfaction is moderated by professional identity.

A Bibliometric Study on Global Snakebite Research Indexed in Web of Science.

Objective: To conduct a bibliometric analysis of the global snakebite literature to provide a reference for the future development of snakebite research. Methods: The Web of Science citation analysis tools, VOSviewer and CiteSpace V were used to carry out the bibliometric analysis of the literature and generate visualization maps. Results: The number of publications has increased at a considerably accelerated rate in the past 8 years. Nine distinct cooperation clusters were formed between institutions and countries. Keyword clustering yielded nine well-structured clusters covering two major topics, i.e., snakebite envenoming and antivenom. Burstiness detection revealed eight keywords with strong emergence, including neglected tropical diseases, Elapidae, Viperidae, and Russell's viper, which have sustained popularity up to the present. Conclusion: Current research on snakebites has gradually garnered attention from the academic community. Cooperation papers between nations severely affected by snakebite and those with higher economic status received more attention. The continued exploration of therapeutic mechanisms, the development of antivenoms or alternative medicines, and primary prevention of snakebites to ensure the safety of populations in impoverished regions should be prioritized by international scholars. The epidemiological evidence and the timely translation of research findings should be valued by policymakers.

Willingness to maintain contracts with family doctors among Chinese residents: results from one national cross-sectional study and a meta-analysis of 25 studies.

Background: A number of studies have investigated the influencing factors regarding the renewal of contracts associated with Family Doctor Contract Services (FDCS) in different regions of China since it was officially implemented in 2009; however, none of the previous studies have been considered using a nationally representative sample in combination with a meta-analysis. Methods: A multistage stratified sampling method was used to investigate participants' socio-demographic characteristics, health status, understanding, use, and evaluation of the FDCS, and their willingness to renew contracts in Eastern, Central, and Western China from September to November 2021. We searched the PubMed, Ovid Medline, CNKI, VIP, Wanfang, and SinoMed databases to retrieve previous studies related to the willingness of Chinese residents to renew contracts with their family doctor (FD), and a meta-analysis was performed to systematically summarize the willingness to maintain contracts and influencing factors. Results: Among 2,394 residents, 2,122 (88.64%) were willing to renew their contracts. The mixed-effect logistic regression model results demonstrated that residents who (1) preferred primary health service institutions, (2) had a better knowledge of FDCS, (3) were more willing to visit primary health service after signing the contract with FDs, (4) were not intending to change FDs, (5) were satisfied with FDCS, and (6) trusted in FDs reported a higher level of willingness to maintain contracts with FDs. Our meta-analysis confirmed that older age, being married, having chronic diseases, choosing primary medical institutions for the first contact, having a good knowledge of FDCS/FDs, being satisfied with FDCS and the medical skills of FDs, and trusting FDs were all positively associated with residents' willingness to renew contracts (p < 0.05). Conclusion: The willingness of consumers to maintain contracts with FDs in China varies in different areas. Giving priority services to groups of high need contributed to an improved rate of renewal. We suggest that in order to continue to increase annual contract renewal, it is necessary to strengthen consumer awareness through effective marketing and continue to work toward meeting consumer expectations, thereby increasing confidence and trust in FDCS.

Prevalence and Risk Factors of Workplace Violence Against Emergency Department Nurses in China.

Objectives: We aim to find out the prevalence, characteristics, and predictors of workplace violence (WPV) against current Chinese emergency department (ED) nurses. Methods: A cross-sectional survey of 20,136 ED nurses was conducted in 31 provinces in China between July and September 2019. Descriptive analyses were used to examine the prevalence and characteristics of WPV. Chi-square analysis and Binary logistic regression analysis were used to identify the predictors of WPV. Results: During the past 12 months, there are 79.39% of ED nurses exposed to any type of WPV, including 78.38% and 39.65% exposed to nonphysical and physical violence, respectively. Binary logistic regression analysis shows that ED nurses who were male, had bachelor's degrees, had average monthly salary between 5,001 and 12,000, worked in central China, had higher professional titles, were more experienced, arranging shift work, and had higher work stress were more likely to experience WPV. Conclusion: A relatively high prevalence of WPV against Chinese ED nurses has been revealed in this study. The characteristics and predictors of WPV remind us to take positive measures to reduce WPV.

Current Status and Associated Factors of Depression and Anxiety Among the Chinese Residents During the Period of Low Transmission of COVID-19.

Background: The outbreak of coronavirus disease 2019 (COVID-19) has contributed to depression and anxiety among the general population in China. The purpose of this study is to investigate the prevalence and associated factors of these psychological problems among Chinese adults during the period of low transmission, which could reflect the long-term depression and anxiety of the COVID-19 outbreak. Methods: A cross-sectional survey was conducted in China from 4 to 26 February 2021. Convenient sampling strategy was adopted to recruit participators. Participants were asked to filled out the questions that assessed questionnaire on the residents' depression and anxiety. Results: A total of 2,361 residents filled out the questionnaire. The mean age was 29.72 years (SD = 6.94) and majority of respondents were female (60.10%). Among the respondents, 421 (17.83%), 1470 (62.26%), and 470 (19.91%) were from eastern, central, and western China, respectively. 1704 (72.17%) consented COVID-19 information has been disclosed timely. 142 (6.01%) and 130 (5.51%) patients suffered from depression and anxiety symptoms. Furthermore, some influencing factors were found, including marital status, place of residence, employment status. Conclusion: This study revealed that anxiety and depression still are potential depression and anxiety for some residents, which suggested early recognition and initiation of interventions during the period of low transmission is still indispensable.

Association between alcohol consumption and the risk of stroke in middle-aged and older adults in China.

OBJECTIVE: This study aimed to investigate the association between alcohol consumption and the prevalence of stroke in Chinese adults aged 40 years and over. METHOD: We conducted a cross-sectional analysis among 113,573 Chinese adults aged ≥ 40 years in the China National Stroke Prevention Project (2014-2015) to examine correlations of alcohol consumption with the prevalence of stroke. Logistic regression models were used to calculate odds ratios (ORs) and 95% confidence intervals (CIs), controlling for various confounders, e.g., gender, age, smoking, physical activity and other health conditions. RESULTS: Within the study population, a total of 12,753 stroke survivors were identified. The prevalence of light to moderate and of heavy alcohol consumption was 10.1% and 5.7% respectively. The multivariate logistic regression results show that light to moderate alcohol consumption was associated with reduced risk of stroke of all types [0.91 (95%CI: 0.85-0.97)] and of ischemic stroke [0.90 (0.84-0.97)]. No association was found between alcohol consumption and hemorrhagic stroke. Compared with abstainers, the adjusted ORs of all stroke were 0.83 (0.75-0.92) for those who drank 11-20 years, and no association was found between 1 and 10 years or over 20 years of drinking and risk of stroke. CONCLUSIONS: These results indicate that light to moderate alcohol consumption may be protective against all and ischemic stroke, and heavy drinking was not significantly associated with risk of all stroke in China. No association between alcohol consumption and hemorrhagic stroke was found.

Another New Year, Will the Chinese Residents Wear Face Masks Again? A Cross-Sectional Survey.

Background: As more and more countries enter the low-transmission phase, maintaining prevention awareness among the population is critical to prevent a secondary outbreak. With large-scale interpersonal communication, whether Chinese residents can maintain a high awareness of prevention and control and adhere to the use of masks during the Chinese New Year of 2021 is worth studying. Methods: A cross-sectional survey was conducted in China from February 4 to 26, 2021. A convenient sampling strategy was adopted to recruit participators. Participants were asked to fill out the questions that assessed the questionnaire on face mask use. Descriptive statistics were used to assess the mask-wearing behaviors of the public. A binary logistic regression analysis was performed to identify the risk factors affecting mask-wearing behaviors. Results: A total of 2,361 residents filled out the questionnaire. In the mixed-effect logistic regression analysis, Chinese residents who were older (OR = 7.899, 95%CI = 4.183-14.916), employed (OR = 1.887, 95%CI = 1.373-2.594), had a chronic disease (OR = 1.777, 95%CI = 1.307-2.418), reused face masks (OR = 22.155, 95%CI = 15.331-32.016) and have read the face mask instructions (OR = 3.552, 95%CI = 1.989-6.341) were more likely to use face masks in interpersonal communication during the Spring Festival; while people who have breathing discomfort caused by face masks (OR = 0.556, 95%CI = 0.312-0.991) and considered that using masks repeatedly is wasteful (OR = 0.657, 95%CI = 0.482-0.895) were more unlikely to use face masks. Conclusions: Our results revealed that 83.86% of people wore face masks during the Chinese New Year; however, some aspects require further promotion. By investigating the use of masks by Chinese residents during the Spring Festival and its influencing factors, we can reflect the prevention awareness of the residents during the low transmission period of COVID-19, which can provide a reference for Chinese and global public health policymakers.

Prevalence and Risk Factors of Home Quarantine Strategy Implementation Among Chinese Residents During the Coronavirus Disease 2019 Pandemic.

Background: Home quarantine is an important strategy to contain the mass spread of the coronavirus disease 2019 (COVID-19) pandemic. However, there are a dearth of studies on the prevalence and risk factors of home quarantine strategy implementation among residents. This study aims to assess the state of home quarantine strategy implementation among Chinese residents, which could provide a reference for quarantine policymakers around the world during the pandemic. Method: We conducted a cross-sectional survey of 3,398 residents in China by adopting a convenience sampling strategy. We measured the prevalence and risk factors of home quarantine strategy implementation with the Center for Epidemiological Studies-Depression Scale (CES-D), 10-item Connor-Davidson Resilience Scale (CD-RISC 10), and Perceived Social Support Scale (PSSS). A multivariable model was used to determine the factors associated with home quarantine strategy implementation. Results: A total of 2,936 (86.4%) respondents carried out home quarantine. There were some factors significantly associated with home quarantine strategy implementation among Chinese residents during the COVID-19 outbreak. Respondents who were male, lived in western and central China, were aware of the primary symptoms of COVID-19, were willing to accept recommendations on relevant protective measures, understood local quarantine measures, had better resilience, and had better social support were more likely to engage in home quarantine. Respondents who were married, were employed, were healthy, and had high depression scores were more likely to refuse to follow home quarantine guidance. Conclusions: Gender, region, marital status, employment status, health status, awareness of the primary symptoms of COVID-19, willingness to accept recommendations on relevant protective measures, understanding of local quarantine measures, depression, psychological resilience, and perceived social support were the main factors affecting the implementation of residents' home quarantine strategy. Health service policymakers should adopt relevant measures to improve the prevalence of home quarantine strategy implementation among residents during the pandemic.

Post-traumatic Stress Disorder and Associated Factors 1 Year After the Beginning of the COVID-19 Pandemic Among Chinese Residents.

Background: By investigating the incidence of post-traumatic stress disorder (PTSD) among residents during a period of low transmission, this study reflects the long-term impact of coronavirus disease 2019 (COVID-19) and identify which categories of residents are more likely to develop PTSD due to an acute infectious disease crisis, facilitating the development of targeted strategies to protect mental health after outbreaks of similar acute infectious diseases in the future. Methods: A cross-sectional survey was conducted in China from 4 to 26 February 2021. A convenience sampling strategy was adopted to recruit participants. Participants were asked to complete the PTSD Checklist for DSM-5 (PCL-5). A multivariable linear stepwise regression analysis model was used to identify which factors were associated with PTSD in residents of China. Results: A total of 2,361 Chinese residents completed the questionnaire. The mean PCL-5 score for the respondents was 13.65 (SD = 8.66), with 219 (9.28%) patients having probable PTSD symptoms. Respondents who were female (ß = 0.038), had a relative or friend who had contracted COVID-19 (ß = 0.041), and had poor health (ß = 0.184) had higher PCL-5 scores, while the population aged over 60 years (ß = -0.063), who agreed that COVID-19 information was released in a timely manner (ß = -0.347), who had experienced a relatively limited impact of COVID-19 on their life (ß = -0.069), and who agreed that the local prevention initiatives were sophisticated (ß = -0.165) had lower PTSD scores. Conclusions: Outbreaks of acute infectious diseases can have long-term psychological health effects in the general population. In addition, health policy makers need to be concerned about and implement measures to support the mental health of vulnerable groups.
