ABSTRACT
Background: Smartphone addiction among adolescents is an increasingly recognized problem worldwide. It affects the psychological well-being of an individual. Aim and objective: The current study aimed to assess smartphone addiction’s prevalence and its relation to depression among adolescents. Methods: This cross-sectional study was conducted among 400 school-going adolescents. Smartphone Addiction Scale - Short version (SAS-SV) and Patient Health Questionnaire (PHQ-9) were used to assess the prevalence of smartphone addiction and depression. Data were analyzed using Epi info software for windows (CDC, Atlanta). Statistical significance was set at p < 0.05. Results: The mean age of study participants was 14.4 years (SD=1.5 years). The prevalence of smartphone addiction was 23%, while depression was present among 45% of the study participants. Comparatively higher duration of smartphone use was significantly associated with smartphone addiction. Depression was significantly higher among smartphone addicts (77.2%) as compared to their counterparts (35.4%). Conclusion and Recommendation: The smartphone usage of adolescents, if not monitored, could lead to its addiction and thus increase the risk of depression among them. To prevent smartphone addiction, limiting children’s screen time is recommended. In this regard, parents can play a pivotal role by becoming responsible digital role models for their children.
ABSTRACT
Objective@#To construct an evaluation index system of public health emergency preparedness capacity in county-level centers for disease control and prevention (CDC), so as to provide the evidence for improving the public health emergency preparedness capacity in county-level CDC.@*Methods@#An index system framework was created based on review of health emergency policies, laws and regulations released in China from 2003 to 2023. The importance, sensitivity and accessibility of indicators were scored and screened through two rounds of Delphi expert consultations, and the weights of indicators were calculated using precedence charts. The efficiency of Delphi expert consultations was evaluated using the active coefficient, authority coefficient and coordination coefficient. @*Results@#Eighteen experts participated in consultations, including 9 men, 15 with educational levels of master degree and higher, 12 with preventive medicine or public health as the specialty, and 12 with deputy senior professional titles and higher. The active coefficients of two rounds of consultations were 100.00% and 94.44%, and the authority coefficients were 0.83 and 0.84, respectively. The coordination coefficients of secondary and tertiary indicators during the second round consultation were 0.341 and 0.241, which were both higher than those during the first round (both P<0.05). The final evaluation index system included 8 primary indicators, 21 secondary indicators and 58 tertiary indicators. Among primary indicators, health emergency organization and management (0.203 1), health emergency team building (0.203 1) and financial support for health emergency (0.203 1) had the highest weights, and of secondary indicators, completion degree of health emergency administration regulations (initial weight/global weight: 0.750 0/0.152 3), health emergency team building (0.750 0/0.152 3) and financial support for emergency (0.750 0/0.152 3) had the highest weights, while among tertiary indicators, defining the duty of health emergency administration sectors had the highest weight (0.750 0/0.114 2). @*Conclusion@#The created evaluation index system is feasible for evaluation of the public health emergency preparedness capacity in county-level CDC.
ABSTRACT
Objective:To evaluate the implementation of national continuing medical education (CME) base programme about infectious disease control and prevention during 2013-2020, so as to improve the quality management of CME.Methods:According to data from national CME system, Excel and SPSS 27.0 were used to analyze project hosting days, places, teachers, students, project directors and training effect. The counting data were expressed by frequency and percentage [cases (%)], chi-square test was used to make comparison between groups, Mantel-Haenszel chi-square test was used for trend test, and the significance test level of the difference was α = 0.05. Results:A total of 116 projects were conducted from 2013 to 2020, with execution rate of 87.9%(116/132). Most hosting days were 2 to 3 days [57.8% (67/116)]. The majority [65.2% (5 785/8 871)] of trainees had junior and intermediate technical titles. As for trainers, trainers with senior technical titles accounted for 87.6% (758/865), and those with intermediate titles accounted for 12.4% (107/865). Mantel-Haenszel chi-square test showed that there was a linear relationship between the proportion of technical titles and the year ( χ2趋势 = 4.97, P趋势 = 0.026). Project directors almost had senior professional title, and nearly one third of them had the experience of undertaking three or more base projects within 8 years. The top three training modules were parasitic diseases prevention and control, AIDS prevention and control, and viral diseases prevention and control. Trainees were highly satisfied with the training contents. Conclusion:The implementation of the infectious disease prevention and control base programme went well in general from 2013 to 2020. In the future, it’s needed to be demand-oriented, rationally design training programs, enhance the evaluation of training effects, strengthen the construction of public health core capacity, and adopt a strategy of brand development in the process of the infectious disease prevention and control base programme.

ABSTRACT
India started Point of entry (PoE) surveillance at Mumbai International Airport, screening passengers returning from coronavirus disease (COVID?19)?affected countries using infrared thermometers. We evaluated in July 2020 for March 1–22 with the Centers for Disease Control and Prevention evaluation framework. We conducted key informant interviews, reviewed passenger self?reporting forms (SRFs) (randomly selected) and relevant Airport Health Organization and Integrated Disease Surveillance Programme (IDSP) records. Of screened 165,882 passengers, three suspects were detected and all were reverse transcription?polymerase chain reaction negative. Passengers under?quarantine line?listing not available in paper?based PoE system, eight written complaints: 6/8 SRF filling inconvenience, 3/8 no SRF filling inflight announcements, and standing in long queues for their submission. Outside staff deployed 128/150 (85.3%), and staff: passenger ratio was 1:300. IDSP reported 59 COVID?19 confirmed cases against zero detected at PoE. It was simple, timely, flexible, and useful in providing information to IDSP but missed cases at PoE and had poor stability. We recommended dedicated workforce and data integration with IDSP.
ABSTRACT
ObjectiveTo evaluate the current situation of human resource allocation in district and county centers for disease control and prevention （CDCs） in Kashgar ， identify existing problems and influencing factors， and to provide scientific evidence for optimizing the human resource allocation. MethodsA survey was conducted among all CDCs in Kashgar in February 2022. The questionnaire included the institutional and individual questions. ResultsThe overall staff size approved for the CDCs in Kashgar was 604， with a staffing rate of 76.17%， among which the staffing rates in 5 county CDCs were less than 60%. Currently， there were a total of 524 approved staff members in all CDCs， resulting in a vacancy rate of 13.25%. In the district CDC， 85 staff members were on duty， while the median of staff on duty was 34 in each county CDC. The staff in the district CDC was ageing， of which those aged over 45 accounted for 67.06%. The staff in the county CDCs was generally young， of which those aged less than 35 accounted for 54.22%. Moreover， the proportion of staff with bachelor’s degree or above in the district and county CDCs was 31.76% and 24.95%， respectively. The proportion of staff without professional title was 32.94% and 48.03%， respectively. In contrast， the proportion of those with middle and senior professional title was 57.89% and 22.02%， respectively. In addition， in recent 3 years， 24 staff members resigned in the CDCs， all of whom had professional titles. ConclusionHuman resources are insufficient in CDCs in Kashgar. Furthermore， staff structure is unreasonable， with a serious loss of human resources. In particular， the district CDC needs to optimize the allocation of human resources.
ABSTRACT
Objective:To analyze the horizontal scientific research projects from 2015 to 2019 by the provincial Centers for Disease Control and Prevention (CDC) in China, and to compare the regional differences, in order to provide the suggestion on the scientific management of CDC.Methods:The horizontal scientific research projects from 2015 to 2019 were retrospectively analyzed by questionnaire survey. Multiple linear regression models were adopted to examine the trend, and variance analyses were used to test the differences in horizontal scientific research projects among the Eastern, Central, and Western regions.Results:From 2015 to 2019, provincial CDC have received RMB 124.3 million of horizontal scientific research project funds totally, of which 51.9% were funded by enterprises, and 86.9% were undertaken by provincial CDC themselves. There were no statistical significance in the change of research project funds obtained by provincial CDC ( F=0.46, P = 0.764) during this period.The number of horizontal scientific research projects undertook or participated by provincial CDC in the Eastern region were more than that of the Central and Western region ( F = 5.85, P = 0.004; F = 5.03, P = 0.008). Conclusions:The horizontal scientific research projects obtained by the provincial CDC remained stable in recent years while distribution was unbalanced in the region areas. It is suggested to innovate the management mode of scientific research projects with strengthening the trans-agency, trans-department and trans-regional cooperation.

ABSTRACT
Objective To assess the psychological status of staff at the centers for disease control and prevention(CDC) in Sichuan during the outbreak of coronavirus disease 2019(COVID-19) and explore the influencing factors. Methods The staff at Sichuan provincial,municipal,and county(district)-level CDC were selected by convenience sampling.Their basic information,work status,training status,work difficulties,and support from the work group were collected from the self-filled questionnaires online.The Generalized Anxiety Disorder Scale and the 9-question Patient Health Questionnaire were respectively employed to measure the anxiety and depression of the staff.The stepwise Logistic regression was carried out to analyze the influencing factors of anxiety and depression in CDC staff. Results Among the 653 staff,58.35% and 50.06% presented anxiety and depression,respectively.The regression results showed that age(OR=0.95,95%CI=0.92-0.97) and mental support from the work group(OR=0.61,95%CI=0.45-0.82) were the protective factors while physical fatigue(OR=1.82,95%CI=1.20-2.74),work pressure(OR=1.61,95%CI=1.21-2.12),and insufficient protective equipment(OR=1.92,95%CI=1.06-3.49) were the risk factors for depression of CDC staff.Age(OR=0.97,95%CI=0.94-0.99),length of sleep per day(OR=0.74,95%CI=0.56-0.96),and participation in technical training(OR=0.33,95%CI=0.12-0.95) were the protective factors while mental fatigue(OR=1.68,95%CI=1.18-2.41),work pressure(OR=2.94,95%CI=2.08-4.17),and unclear incentive system for overtime(OR=1.99,95%CI=1.23-3.23) were the risk factors for the anxiety of CDC staff. Conclusion The anxiety and depression status of CDC staff during the COVID-19 outbreak were worrying,which were mainly affected by age,sleep,supply of protective equipment,incentive system,fatigue,and work pressure.

Background Since the outbreak of the COVID-19 epidemic, staff of the centers for disease control and prevention (CDC) have been burdened with heavy epidemic prevention control, and excessive occupational stress can cause depression and other psychological problems. Objective To explore the status of occupational stress, resilience, and depression of CDC staff and potential relationships between them. Methods From December 2020 to April 2021, a survey was conducted at provincial and municipal levels, and the stratified cluster sampling method was used at county (district) level to select a total of 3514 samples. Their occupational stress, resilience, and depression status were evaluated using the Chinese Effort-Reward Imbalance Scale (ERI), the Chinese Connor-Davidson Resilience Scale (CD-RISC), and the Patient Health Questionnaire (PHQ-9). Independent sample t test, analysis of variance, χ2 test, Pearson correlation analysis, and mediation test (structural equation model) were conducted. Results The positive rate of occupational stress was 34.29% in the CDC staff, the resilience score was 66.28±15.32, and the positive rate of depression was 48.58%. Significant differences were found in the positive rates of occupational stress among different groups of gender, age, education background, marital status, administrative duty, weekly exercise frequency, chronic disease prevalence, and participation in epidemic control (P<0.05); in the resilience scores among different groups of gender, age, administrative duty, weekly exercise frequency, chronic disease prevalence, and participation in epidemic control (P<0.05); in the positive rates of depression among different groups of gender, age, educational background, personal monthly income, weekly exercise frequency, chronic disease prevalence, and participation in epidemic control (P<0.05). Occupational stress was negatively correlated with resilience (r=−0.165, P<0.01). Resilience was negatively correlated with depression (r=−0.383, P<0.01). Occupational stress was positively correlated with depression (r=0.343, P<0.01). The structural equation embracing a partial mediating effect of resilience on the relationship occupational stress and depression was established, and the partial mediating effect was 0.039, accounting for 10.46% of the total effect. Conclusion High positive rates of occupational stress, reduced resilience, and depression are shown among CDC staff in the context of the COVID-19 epidemic, and resilience partially mediates the effect of occupational stress on depression. The study findings suggest that improving resilience may reduce occupational stress and depression in CDC staff.
ABSTRACT
Background By analyzing the publication of scientific and technological papers of the provincial centers for disease control and prevention (CDCs) in China, we can understand their scientific research strength, dominant disciplines, research hotspots, and talent development, which is conducive for further optimizing the scientific research construction of the disease control system. Objective To conduct a bibliometric analysis and draw a visual map of the Chinese Science Citation Database (CSCD) sourced papers published by 31 provincial CDCs in China from 2011 to 2020, to understand the scientific research status of China's provincial CDC system in the past ten years. Methods In April 2021, China National Knowledge Infrastructure was used to retrieve CSCD sourced papers published by 31 provincial CDCs (excluding Taiwan Province, Hong Kong and Macau Special Administrative Regions) in China as the primary unit from 2011 to 2020, and finally 5231 CSCD papers were included. Bibliometric analysis indicators include number of CSCD papers published and financial support rate, proportion of CSCD papers to total Chinese papers, distribution of CSCD papers published in high-volume journals, and number of papers for a specific CDC that their first authors affiliated with. Citespace 5.8.R1 software was used to draw author's cooperation network map, keyword co-occurrence map, keyword clustering information table, and keyword emergence map. Results The number of CSCD papers published every year showed a stationary trend, and the total funding rate was 61%, showing an year-by-year upward trend (increased from 49.3% in 2011 to 68.7% in 2020). Jiangsu Province, Fujian Province, and Beijing CDCs ranked the top three in the total number of CSCD papers contributed by a specific CDC. The Chinese Journal of Epidemiology, Chinese Journal of Public Health, Chinese Journal of Zoonoses, Chinese Journal of Preventive Medicine, and Chinese Journal of Endemic Diseases were the top five high-volume journals. The top three authors of CSCD papers (counted as co-authors) were Xu Bianli of Henan Provincial Center for Disease Control and Prevention (110 papers), Yan Yansheng of Fujian Provincial Center for Disease Control and Prevention (72 papers), and Wang Quanyi of Beijing Center for Disease Prevention and Control (71 papers), and they studied the epidemiology of parasitic diseases and infectious diseases, the prevention and treatment of natural epidemic diseases and AIDS, and the epidemiology of infectious diseases, respectively. The keyword co-occurrence map showed that AIDS, zoonotic diseases, hand-foot-mouth disease, etc. (frequency ≥90) were the key research directions of provincial CDCs in the past ten years. The keyword clustering categories were closely related, although there were subtle differences, the topics focused on virus and chronic disease research. The keyword emergence results suggested that the frontiers of research had gradually shifted from infectious diseases such as enterovirus, hantavirus, and Zika virus to food-borne diseases and chronic non-communicable diseases such as tumors and senile diseases over time. Conclusion The number of papers issued by the provincial CDCs in China in the past ten years has shown an overall steady and rising trend. The leading themes of researchers and institutions are infectious diseases, parasitic diseases, etc., while food-borne diseases and elderly diseases are the hot frontiers.
ABSTRACT
Objective@#To investigate the development of public health human resource of the Centers for Disease Control and Prevention (CDCs) in Zhejiang Province from 2016 to 2020, so as to put forward the strategies for the talent team construction of CDCs.@*Methods@#The general information of personnel of CDCs in Zhejiang Province from 2016 to 2020 was collected through China Information System for Disease Control and Prevention. A questionnaire survey and a qualitative interview were conducted to collect the data of staffing, talent training, salary and employee turnover, and to analyze the development of the talent team of CDCs. @*Results@#By 2020, there were 105 CDCs, including 1 provincial, 11 prefectural and 93 county-level CDCs, and 5 277 staff on-the-job. From 2016 to 2020, the number of staff per 10 000 permanent residents in the province, prefecture and county levels were 0.062-0.070, 0.170-0.188 and 0.585-0.604, respectively, which did not meet the standard for the personnel establishment in Zhejiang CDCs; the proportion of the staff with bachelor degree or above increased from 90.05% to 94.25%; the proportion of the health professionals decreased from 82.91% to 80.01%; the proportion of the staff with senior professional titles increased from 35.20% to 45.25%. The results of the qualitative interview indicated a lack of health professionals and high-end talents, a gap between the approved staffing and post requirements, as well as demands for a stable team and higher pay. @*Conclusion@#From 2016 to 2020, the structure of educational background, major and professional title among the on-the-job staff of CDCs in Zhejiang Province has been improving; however, the total allocation of human resource is insufficient, and the stability and treatment of staff need to be further improved.

ABSTRACT
Objective:To determine the current situation of food safety risk monitoring ability of centers for disease control and prevention （CDCs） in a province， and provide reference for strengthening the construction of food safety monitoring ability in the future. Methods:A self-administered questionnaire survey was conducted among 14 CDCs who are responsible for food safety risk monitoring in the province in 2018. Results:The ratio of food inspection staff with senior， middle， and primary professional titles was 1∶1∶1. The educational background of food inspection staff at the provincial and municipal levels was mainly bachelor degree or above， while that of county level directly under the administration of the province was mainly college degree. The age composition of the staff at the provincial level tended to be elder； however， there were more staff with less working experience at the county level. The qualification proportion of laboratory area was 50%. The distribution proportion of food inspection equipment in the CDC at all levels was 83.3%， 79.5% and 36.3%， respectively. In total， 14 CDCs completed the monitoring task as required. They were all accredited with laboratory qualifications； however， one CDC did not conduct re-evaluation after the certification of food inspection qualification expired. Each CDC ensured the accuracy and reliability of monitoring data through the supervision in food testing. Conclusion:The food safety risk monitoring ability of the CDCs in the province is continuously improved， which can meet the needs of routine monitoring. However， the composition of professional titles of food inspection staff is not very reasonable. There is still a gap between the equipment configuration and the national requirements. The ability of food inspection needs to be improved， in which quality management and laboratory qualification should be further strengthened.
ABSTRACT
After the epidemic of novel Coronavirus Disease 2019(COVID-19), construction of disease prevention and control has become a top priority. As a pioneer in the recovery of global economy and society, Shanghai should play a fundamental role in building a comprehensive system of public health and advanced disease prevention and control in the new era. In this article, we systematically categorize the requirements for the construction of disease prevention and control system in the new era, identify the weakness and challenges during and after the epidemic, and then make suggestions. It is proposed that we should utilize the important window period of the"14th Five-Year Plan", with the"Healthy China"strategy and municipal"20 Tasks for Public Health Construction"as the starting point, to make substantial contribution to the functional orientation, investment of resources, capacity building, operational mechanism and team building, which may provide scientific evidence for the reform and development of disease prevention and control system.
ABSTRACT
Objective To analyze the current situation of financing in disease control and prevention constitutions in China, to identify existing problems, to explore potential reasons, and to make policy recommendations accordingly. Methods Financial related indicators, including revenue and expense of disease control and prevention institutions, were collected through questionnaire survey. Moreover, some disease control and prevention institutions were selected for on-site survey. Results The proportion of public health institutions in the Total Health Expenditure had fallen from 7.0% in 2014 to 5.6% in 2018. The proportion of financial compensation in the operation of disease control and prevention institutions was less than 50%. The gap between revenue and expenditure had not been covered completely after the cancellation of three categories of administrative charges. In addition, financing mechanism of public health service funds remained unclear. Conclusion We recommend the strategies, including optimizing financing structure, increasing investment in disease control and prevention, increasing the level of financial guarantee, improving the mechanism of public health service funds, and multi-channel financing.
ABSTRACT
Objective To analyze the staff structure, turnover and income of human resources in disease control and prevention institutions(CDCs)at different levels in China, to identify the existing problems, and to make policy recommendations accordingly. Methods A questionnaire survey was used to collect the data on the staff of CDCs at different levels in China from 2016 to 2018. Descriptive analysis and trend analysis were conducted on the number of staff, recruitment and turnover, income and other indicators in the three years. Results A total of 606 CDCs were included in the study. The proportion of job openings was 11.97% in 2018. Although the median proportion of professional personnel and health professional personnel in the CDCs reached the national standard(85% and 70%, respectively), a considerable number of institutions failed to meet the national standard. From 2016 to 2018, staff turnover in the CDCs has been increasing, with a minimum of 0.73(in 2016, municipal CDCs)and a maximum of 10.52(in 2018, provincial CDCs). In the staff who quit the CDCs, the proportion of junior professionals was the highest, while that of medium and senior professional increased gradually. Of them, the proportion of staff with graduate education in eastern China and provincial CDCs was higher than that of undergraduate education, while the proportion of staff with graduation education in other regions also increased. From 2016 to 2018, the average annual income in the CDCs in most regions did not reach the national average wage level of urban employees in health, social security and social welfare field in the same period. In county and district level CDCs in central and western China, personal income in 2018 was even less than the national average wage level in 2016. Conclusion Human resources in the CDCs at different levels in China remains insufficient and unbalanced, which warrants a"supporting policy"mechanism for public health personnel. The loss of the personnel in the CDCs continues to increase, in which the loss of senior professionals become increasingly serious. It raises a new concern to establish and improve the incentive mechanism of public health personnel. Furthermore, personal income in the CDCs is lower than the local average level. It is necessary to set personal income reasonably according to local economic level.
ABSTRACT
Social distancing was planned as a preventive measure to control the extensive spread of COVID-19. COVID-19-related deaths in Brazil were analyzed during the period of social distancing measures. Mortality data for COVID-19 was obtained from the Worldometer website (www.worldometer.info). Deaths were estimated up to the 31st day after the occurrence of the 5th COVID-19-related death in Brazil. Social distance was measured using Google's community mobility reports (https://www.google.com/covid19/mobility/). The Brazilian epidemic curves were interconnected, and mathematical models were evaluated to fit the mortality estimation curves. The optimistic model was defined in the opening period of social distancing and, therefore, in the lower mobility (40-60%). The realistic model was calculated according to relaxed social distance measures (<40%) and the pessimistic model was calculated based on the transmission rate between 2-3. Thus, the equations of the mathematical models provided the outcomes for the date of June 9, 2020, as follows: realistic model with 40,623 deaths, pessimistic model with 64,310 deaths and the optimistic model with a projection of 31,384 deaths. As a result of these analyzes, on May 24, 2020, there were a total of 22,965 deaths related to COVID-19, and those deaths included within the proposed mathematical models were 17,452 for the optimistic model, 22,623 for the realistic model and 32,825 for the pessimistic model. Thus, it is concluded that social distancing measures promoted by the Brazilian public managers contributes to the reduction in approximately ten thousand deaths related to COVID-19 in the current pandemic scenario.
INTRODUÇÃO: O distanciamento social foi planejado como uma medida preventiva para controlar a disseminação extensiva da COVID-19. Nós analisamos as mortes relacionadas à COVID-19 no Brasil durante o período de medidas de distanciamento social. Os dados de mortalidade do COVID-19 foram obtidos no site da Worldometer (www.worldometer.info). As mortes foram estimadas até o 31º dia após a 5ª morte. O distanciamento social foi medido por meio dos relatórios de mobilidade comunitária COVID-19; Google (https://www.google.com/covid19/mobility/). As curvas epidêmicas brasileiras foram interligadas e os modelos matemáticos foram avaliados para se ajustarem às curvas de estimativa de mortalidade. O modelo otimista foi fundado no período de abertura da distância social e, portanto, na menor mobilidade (40-60%). O modelo realista foi calculado de acordo com medidas de distanciamento social relaxado (<40%) e o modelo pessimista foi calculado com base em R0 entre 2-3. Sob essa situação, o modelo matemático realista estimou 40.623 mortes em 9 de junho de 2020, enquanto o modelo pessimista antecipou 64.310 mortes e o modelo otimista projetou 31.384. Até hoje (24 de maio de 2020), um total de 22.965 foram relatadas, enquanto nosso modelo projetou 17.452 para o modelo otimista, 22.623 para o modelo realista e 32.825 para o modelo pessimista. Observamos movimento reduzido ao longo deste período. Em resumo, o modelo matemático sugere que a mobilidade reduzida da comunidade diminuiu o total estimado de mortes relacionadas à COVID-19 no Brasil. Enfatizamos que mais procedimentos metodológicos serão necessários para confirmar esta teoria
