Prevalence of Smartphone Addiction and its Relation with Depression among School-going Adolescents

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.

We conducted a questionnaire survey among 620 staffs selected by convenience sampling, and a qualitative interview among 40 leaders and experts from CDCs and general hospitals in Zhejiang Province. @*Results @#By the year 2020, there were 105 CDCs in Zhejiang Province, including 1 province-level, 11 prefecture-level, 90 county-level and 3 development zone-level ones. The revenues were mainly from financial subsidy and business incomes, which were over expenditures. There were 7 008 posts in CDCs, with a staffing allocation ratio of 1.29/10 000. Among the reform measures of operation mechanism of CDCs, the flexible communication between clinicians and public health doctors was highly approved (90.03%); among the reform measures of enhancing the integration of prevention and treatment, further clarifying the public health functions of hospitals and ensuring financial compensation was highly approved (74.01%).@*Conclusion @#We should further stimulate the endogenous power and vitality of CDCs, strengthen the construction of talent team, promote the active integration of hospitals and CDCs, and improve public health level.

The public health human resource of CDCs in Zhejiang Provincefrom 2016 to 2020 / 预防医学

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.

Social distancing measures could have reduced estimated deaths related to COVID-19 in Brazil / Medidas de distanciamento social podem ter reduzido as mortes estimadas relacionadas à COVID-19 no Brasil

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

Changes of Global Infectious Disease Governance in 2000s: Rise of Global Health Security and Transformation of Infectious Disease Control System in South Korea / 의사학

This paper focus upon the changes of global infectious disease governance in 2000s and the transformation of infectious disease control system in South Korea. Traditionally, infectious disease was globally governed by the quarantine regulated by the international conventions. When an infectious disease outbreak occurred in one country, each country prevented transmission of the disease through the standardized quarantine since the installation of international sanitary convention in 1892. Republic of Korea also organized the infectious disease control system with quarantine and disease report procedure after the establishment of government. Additionally, Korea National Health Institute(KNIH) was founded as research and training institute for infectious disease. However, traditional international health regulation system faced a serious challenge by the appearance of emerging and re-emerging infectious disease in 1990s. As a result, global infectious disease governance was rapidly changed under the demand to global disease surveillance and response. Moreover, global health security frame became important after 2001 bioterror and 2003 SARS outbreak. Consequently, international health regulation was fully revised in 2005, which included not only infectious disease but also public health emergency. The new international health regime was differently characterized in several aspects; reinforcement of global cooperation and surveillance, enlargement of the role of supranational and international agencies, and reorganization of national capacity. KNIH was reorganized with epidemic control and research since late 1990s. However, in 2004 Korea Center for Disease Control and Prevention(KCDC) was established as a disease control institution with combining quarantine and other functions after 2003 SARS outbreak. KCDC unified national function against infectious disease including prevention, protection, response and research, as a national representative in disease control. The establishment of KCDC can be understood as the adoption of new international health regulation system based upon SARS experience.

2000 CDC or 2007 WHO – What is the most sensitive anthropometric reference for determination of overweight and cardio-metabolic risk in children aged 6–10 years?

Objective To compare the two anthropometric standards for screening of overweight and cardio-metabolic risk in 6–10-year-old children.Subjects and methods This cross-sectional study included 175 subjects attending the Referral Center for the Treatment of Children and Adolescents in Campos, Rio de Janeiro. They were classified according to CDC and WHO BMI z scores as normal-weight (z-score > –1 and < 1), overweight (z-score ≥ 1 and < 2) or obese (z-score ≥ 2). Sensitivities and specificities in predicting systolic (SBP), diastolic (DBP) blood pressure and homeostatic model assessment insulin resistance index (HOMA-IR) alterations were calculated.Results There was a major difference in 11 children who rated overweight by the CDC but were reclassified as obese by the WHO. Their mean z-scores for SBP (1.71 ± 1.54), DBP (2.64 ± 1.83) and HOMA-IR (1.84 ± 0.98) were higher than those classified as overweight by both references (SBP = 0.49 ± 1.34, p < 0.023, DBP = 1.45 ± 0.97, p < 0.04 and HOMA = 1.24 ± 0.67, p < 0.04), but were similar to those classified as obese by both criteria (SBP = 1.25 ± 2.04, p = 0.60, DBP = 1.94 ± 1.19, p = 0.50 and HOMA = 2.09 ± 1.12, p = 0.76).Conclusion the 2007 WHO reference was the most sensitive in screening for overweight and alterations in blood pressure and HOMA-IR in 6–10-year-old children.

MATERIALES Y MÉTODO Se realizó un estudio observacional transversal descriptivo en una población de 58 pacientes adultos de 35-44 años pertenecientes al CESFAM Lorenzo Arenas, Concepción, en el año 2013. Los examinadores fueron calibrados. Se realizó un examen con registro de boca completa midiendo 6 sitios por diente, con exclusión de los terceros molares, para medir pérdida de inserción clínica, profundidad de sondaje y hemorragia al sondaje. Los resultados se analizaron mediante el programa estadístico EPIDAT 3.0. RESULTADOS Se determinaron unos valores de prevalencia de EP muy distintos entre los indicadores evaluados, obteniéndose una variación de incluso 31 puntos en una escala porcentual. El análisis de la concordancia de los índices periodontales con el indicador CDC/AAP mostró que tanto ICEP, como CPI y CPITN lograron un buen valor kappa. CONCLUSIÓN A pesar de la gran diversidad de los índices con respecto a su formulación, se observó cierta concordancia entre algunos de ellos.

INTRODUCTION The study of periodontal disease (PD) has shown inaccurate and heterogeneous results due to various factors, among them: most used methods to measure the illness, differences at the time of deciding the level in which it affects patients and the values from which a patient would be considered to suffer from PD. There are numerous periodontal indexes frequently used in epidemiological studies, each one with different criteria and measurement protocols. OBJECTIVE To establish the agreement in PD prevalence value given by some periodontal indexes used. MATERIALS AND METHOD A descriptive cross-sectional observational study was conducted on 58 adult patients between 35-44 years old belonging to Lorenzo Arenas Primary Health Care Center in Concepcion during the year 2013. All examiners who participated in the study were calibrated. A full mouth registration exam was carried out, measuring 6 places per tooth, not including the third molars, in order to measure the clinical attachment loss, probing depth, and bleeding on probing. The results were analyzed using EPIDAT 3.0 statistical program. RESULTS Very different PD prevalence values were obtained using the measured indicators, having a variation of up to 31 points in a percentage scale. The analysis of the agreement in periodontal indexes with the CDC/AAP indicator showed ICEP, CPI and CPITN scored a good kappa value. CONCLUSION Despite the great diversity of the indices with respect to their formulation, some correlation between them was observed.

Trends of Recent Food-Borne Disease Outbreaks in Korea

This report summarizes recent food-borne disease outbreaks in Korea by month, pathogen, dining place, and scale. In particular, imported cases are described separately. Sources of information include surveillance and statistic data and reports of KCDC/MOHW and KFDA, and scientific journals from home and abroad. Investigation results indicate that reports of food-borne disease cases and imported cases are increasing continuously in Korea. Many cases still occur in May and June, and new cases increasingly occur in December. Other new characteristic of the recent outbreaks is that they are increasingly attributable to pathogens such as Norovirus and EHEC. Outbreaks at mass meal preparation facilities represent a large proportion of cases, mainly due to the increase in the possibilities for common exposure, pathogen mobility, meat consumption, and the detection itself. To address this health problem, water and sewer service must be widely provided, food materials must be handled thoroughly, and good personal hygiene including proper hand washing must be further underscored. As a responsible agency, KCDC will also need to conduct thorough epidemiological investigations, establish an efficient surveillance system, work in a prompt manner, and enhance partnerships with various agencies.
