RESUMO

Previous studies in the context of the COVID-19 pandemic indicated that wearing a medical-style mask affects whether a stranger's face is judged as more trustworthy, socially desirable, or likely to be ill. However, given political controversies around mask use, these effects might vary by political orientation. In a pre-registered online experiment, we measured evaluations of trustworthiness, social desirability and perceived illness in masked and unmasked faces by 1241 British and US participants. We included questions on political orientation, along with the implicit online-VAAST approach/avoid task to test reaction times to masked/unmasked faces. There was a medium-sized effect of masks on trustworthiness and a significant interaction with political orientation, in that conservatives found masked faces less trustworthy than did liberals. Participants were quicker to approach masked than unmasked faces, but conservatives were relatively slower than liberals. The effects on trustworthiness suggest that differential moralization of novel social norms can affect how their adherents are evaluated in terms of their suitability for social interactions. Furthermore, the congruence between implicit and explicit methods implies that such differences can have deep-seated effects on reactions.

RESUMO

Until this moment, no research has been found that has assessed adherence to online nutritional monitoring by adults with Diabetes Mellitus Type 1 (T1DM) during the pandemic. This article aims to analyze the association between eating habits and adherence to nutritional online care by adults with T1DM during social distancing because of the COVID-19 pandemic in Brazil. A cross-sectional study was carried out in July 2020. An online form was used to collect sociodemographic data, financial status, eating habits, carrying out online nutritional monitoring, and adherence to social distancing. Pearson's chi-squared test was performed with adjusted residual analysis and binomial logistic regression analysis (p < 0.05). Out of the 472 adults, only 8.9% had consulted with a nutritionist. Doing nutritional monitoring online during social distancing was associated with a reduction in the consumption of ultra-processed foods (p = 0.021), eating more servings of fruit (p = 0.036), and doing carbohydrate counting (CC) more frequently (p = 0.000). Doing nutritional monitoring online increased adherence to carbohydrate counting by 2.57 times and increased the consumption of fruits by 0.423 times. Therefore, nutritional monitoring, even if performed remotely, can influence the acquisition and maintenance of healthier eating habits, in addition to assisting adherence to the practice of CC.

RESUMO

The epidemiology of COVID-19 presented major shifts during the pandemic period. Factors such as the most common symptoms and severity of infection, the circulation of different variants, the preparedness of health services, and control efforts based on pharmaceutical and non-pharmaceutical interventions played important roles in the disease incidence. The constant evolution and changes require the continuous mapping and assessing of epidemiological features based on time-series forecasting. Nonetheless, it is necessary to identify the events, patterns, and actions that were potential factors that affected daily COVID-19 cases. In this work, we analyzed several databases, including information on social mobility, epidemiological reports, and mass population testing, to identify patterns of reported cases and events that may indicate changes in COVID-19 behavior in the city of Araraquara, Brazil. In our analysis, we used a mathematical approach with the fast Fourier transform (FFT) to map possible events and machine learning model approaches such as Seasonal Auto-regressive Integrated Moving Average (ARIMA) and neural networks (NNs) for data interpretation and temporal prospecting. Our results showed a root-mean-square error (RMSE) of about 5 (more precisely, a 4.55 error over 71 cases for 20 March 2021 and a 5.57 error over 106 cases for 3 June 2021). These results demonstrated that FFT is a useful tool for supporting the development of the best prevention and control measures for COVID-19.

RESUMO

A Covid-19, doença infecciosa causada pelo vírus SARS-CoV-2, emergiu na China em dezembro de 2019 e rapidamente se espalhou por todo o mundo. A infecção foi declarada pandemia pela Organização Mundial de Saúde (OMS) em 11 de março de 2020. Desde então, o distanciamento social, entre outras medidas de proteção, foi adotado para desestruturar a cadeia de transmissão do vírus. Contudo, as desigualdades nas oportunidades para se valer dessa medida de proteção foram constatadas. O presente estudo examinou as chances de desligamento por morte de empregados celetistas em Minas Gerais, no período de 2019 a 2021, de acordo com as características sociodemográficas e ocupacionais da força de trabalho registrada no Cadastro Geral de Empregados e Desempregados (Novo - CAGED), do Ministério do Trabalho e Emprego (MTE). A hipótese central diz respeito à variação da chance de desligamento por morte em atividades consideradas essenciais no período pandêmico e pós-pandêmico. Estudo transversal utilizou dados secundários disponíveis para acesso no site do MTE. A Classificação Nacional de Atividades Econômicas (CNAE) e a Classificação Brasileira de Ocupações (CBO) foram tomadas como referência para examinar a hipótese principal. As covariáveis de interesse foram sexo, idade, escolaridade, raça/cor, renda. A distribuição do total de empregados registrados e daqueles desligados por morte, em 2019, 2020 e 2021, foi descrita de acordo com os grandes grupos e subgrupos da CBO. Modelos probabilísticos estimados por regressão logística (RL) binária foram usados para avaliar as chances de desligamento por morte. Foram desenvolvidas RL geral por natureza da ocupação e específicas por subgrupos ocupacionais de três grupos ocupacionais estruturados para fins do estudo, sendo os seguintes: setor saúde, setor essencial fora da saúde e setor não essencial. Homens, pessoas mais velhas, com menor nível de escolaridade e de raça/cor branca tiveram maior chance de desligamento por morte. Esse resultado foi mantido em todos os modelos nos três grupos ocupacionais de interesse. Em relação à natureza da ocupação, trabalhadores dos setores saúde e essencial fora da saúde tiveram maior chance de desligamento por morte. No setor saúde, médicos, trabalhadores da enfermagem e cuidadores tiveram maior chance de desligamento por morte. No setor essencial fora da saúde, a maior chance de desligamento por morte foi observada entre os operadores de utilidades (operadores de máquinas a vapor, de instalações de captação e tratamento de água, esgoto e gases) nos três períodos estudados. A taxa de variação da incidência de desligamentos por morte foi considerada marcador próximo da proporção de mortes causadas direta e indiretamente pela Covid-19. Foi observado aumento dessa taxa no período pandêmico, em relação ao período pré-pandêmico. O perfil sociodemográfico da amostra desligada por morte, em 2020 e 2021, é convergente com os estudos sobre mortalidade causada direta e indiretamente pelo SARS-CoV-2, à exceção do resultado sobre raça/cor branca. Essas evidências serão pistas tanto para fomentar o debate sobre as desigualdades nas oportunidades de proteção durante crises sanitárias, quanto impulsionar a formulação de estratégias para reverter a situação de vulnerabilidade dos trabalhadores de setores considerados essenciais.

Covid-19, an infectious disease caused by the SARS-CoV-2 virus, emerged in China in December 2019 and quickly spread worldwide. The infection was declared a pandemic by the World Health Organization (WHO) on March 11, 2020. Since then, several protective measures have been recommended in order to decrease the transmission of the virus. Among the measures recommended by the WHO, social distancing was adopted to disrupt the virus transmission chain. However, inequalities in opportunities to avail of the protective measure have been documented. The present study examined the odds of shutdown due to death of celetal employees in Minas Gerais, in the period from 2019 to 2021, according to the sociodemographic and occupational characteristics of the population registered in the General Cadastre for the Employed and Unemployed (Novo - CAGED), of the Ministry of Labor and Employment (MTE). The central hypothesis concerns the greater odds of shutdown due to death in activities considered essential. This cross-sectional study used secondary data available for access on the MTE website. The National Classification of Economic Activities (CNAE) and the Brazilian Classification of Occupations (CBO) were used as reference to examine the main hypothesis. The covariates of interest were gender, age, education, race/color, and income. The distribution of total registered employees and those dismissed due to death in 2019, 2020, and 2021 was described according to the major groups and subgroups of the CBO. Probabilistic models estimated by binary logistic regression (LR) were used to assess the odds of shutdown due to death. General RL were developed by nature of occupation and specific by occupational subgroups of three occupational groups structured for the purposes of the study, as follows: health sector, essential sector outside of health and non-essential sector. Men, older people, with a lower level of and people of white race/color had a higher odd of shutdown due to death. This result was maintained in all models in the three occupational groups of interest. Regarding the nature of the occupation, workers in the health and non-health essential sectors had a higher odd of shutdown due to death. In the health sector, physicians, nursing workers, and caregivers had the highest odds of being dismissed due to death. In the non-health essential sector, the highest odds of shutdown due to death was evidenced among utility operators (steam machine operators, water, sewage and gas capture and treatment facilities) in the three periods studied. The rate of change in the incidence of shutdown due to death was considered a marker close to the proportion of deaths directly and indirectly caused by Covid-19. An increase in this rate was observed in the pandemic period, in relation to the pre-pandemic period. The sociodemographic profile of the sample shutdowned due to death, in 2020 and 2021, is consistent with studies on mortality directly and indirectly caused by SARS-CoV-2, with the exception of the result on white race/color. This evidence will be clues both to foment the debate on inequalities in protection opportunities during health crises, and to boost the formulation of strategies to reverse the vulnerable situation of workers in sectors considered essential.

RESUMO

A corrupção se configura como um importante problema no Brasil, embora seja entendido como um "crime sem vítimas". Frente à importância do tema, o presente estudo buscou avaliar a influência da categoria social de uma vítima de corrupção na relação entre crenças no mundo justo e intenção de corrupção. A amostra foi composta por 127 estudantes universitários de cursos relacionados às áreas de gestão e negócios. Os participantes responderam a medidas de CMJ, intenção de corrupção e informaram dados sociodemográficos. Verificou-se que, quando uma vítima de corrupção é alguém distante do indivíduo, a intenção de corrupção é maior se comparado a uma condição em que a vítima é próxima. Adicionalmente, verificou-se que o efeito da CMJ na corrupção foi restrito quando da avaliação de uma vítima próxima. Os resultados indicam a importância de articular variáveis grupais (distância social) e pessoais (CMJ) no estudo da corrupção.

Corruption is a major problem in Brazil, although it is understood as a "victimless crime". Given the importance of the topic, this study aimed to assess the influence of the social category of a corruption victim on the relationship between beliefs in a just world and the intention of corruption. The sample consisted of 127 university students from courses related to the areas of management and business. Participants responded to measurements of BJW, the intention of corruption and reported sociodemographic data. It was found that, when a victim of corruption is someone distant from the individual, the intention of corruption is greater compared to a condition in which the victim is close. Additionally, it was found that the effect of BJW on corruption was restricted when assessing a close victim. The results indicate the importance of articulating group (social distance) and personal variables (BJW) in the study of corruption.

La corrupción es un problema importante en Brasil, aunque se entiende como un "crimen sin víctimas". Dada la importancia de la temática, el presente estudio buscó evaluar la influencia de la categoría social de una víctima de corrupción en relación a las creencias del mundo justo (CMJ) y la intención a la corrupción. La muestra consistió en 127 estudiantes universitarios de grados de gestión y negocios. Los participantes respondieron a las escalas de CMJ, intención de corrupción y reportaron datos sociodemográficos. Se ha encontrado que cuando una víctima de corrupción está lejos del individuo, la intención de corrupción es mayor en comparación a una condición en la cual la víctima está cerca. Además, se descubrió que el efecto de CMJ sobre la corrupción estaba restringido al evaluar a una víctima cercana. Los resultados indican la importancia de articular las variables grupales (distancia social) y personales (CMJ) en el estudio de la corrupción.

RESUMO

OBJECTIVE: This study aimed to analyze meal preparation and the place of its consumption by university students before and during the COVID-19 pandemic, according to their individual characteristics and cooking skills. METHODS: Data were collected with 1919 Brazilian university students using the Brazilian Cooking Skills Questionnaire (BCSQ) and questions about gender, living arrangement, knowing how to cook and location of meal consumption. Bayesian multilevel ordinal regression models were used to estimate the probabilities of meal preparation and local location of its consumption by Brazilian university students before and during the COVID-19 pandemic, according to their individual characteristics and cooking skills. RESULTS: Most of participants showed reported a high level of cooking skills (70.7%). Also, they reported a decrease in ordering delivery of take-away food and eating fast-food, while increasing homemade meals with fresh ingredients, ultra-processed food or both during the pandemic compared to the period before the quarantine. Lastly, they increased their cooking frequency during the pandemic, regardless of their cooking skills level. However, the group with high cooking skills had a greater increase in the use of fresh ingredients. CONCLUSIONS: The study showed that the pandemic was an opportunity for university students to increase their cooking skills and frequency of cooking at home with a variety of foods. Particular attention should be given to those with low cooking skills and that use ultra-processed foods, promoting interventions to disseminate information and with behavior change components to teach about healthy cooking to increase cooking knowledge and skills, focusing on preparation of fresh ingredients.

RESUMO

Abstract The objective of this study was to evaluate perception and feelings experienced by dentistry professors and students about distance learning during the COVID-19 pandemic. Fifty professors and fifty- two students reported the perceptions and implications of distance learning imposed by the pandemic of COVID-19. The participants' answers were analyzed using the qualitative-quantitative method of the collective subject's discourse. The answers were summarized in central ideas, distributed in absolute and relative frequency. The answers with similar central ideas were grouped, obtaining the discourse of the collective subject. The similar central ideas about distance learning addressed by professors and students were: suitable for didactic courses; limited laboratory and clinical courses, and internet access difficulties. Specifically for professors: a complement to classroom teaching; stress and learning with digital technologies; difficulty in reconciling classes with domestic activities; concerns with motivation and interaction with students; asynchronous lectures favor knowledge fixation, and synchronous lectures favor interaction with students; unreliable assessment methods; concern about returning to face-to-face classes. For the students: it was applied to all courses; demotivating; fundamental to guide studies; professors' commitment; long lectures; excessive school activities; difficult attendance control and evaluation; the comfort of being at home; impact on research. Professors considered distance learning as a learning opportunity on how to use digital technologies but too limited for lab and clinical activities and interaction with students. Students found it discouraging due to the absence of practical classes and excessive school activities.

Resumen: Evaluar la percepción y los sentimientos manifestados por profesores y estudiantes de odontología sobre la educación a distancia durante la pandemia por COVID-19. 50 profesores y 52 estudiantes informaron las percepciones e implicaciones del aprendizaje a distancia impuestas por motivo de la pandemia de COVID-19. Respuestas de los participantes fueron analizadas utilizando el método cualitativo-cuantitativo del discurso del sujeto colectivo. Respuestas se agruparon en ideas centrales, obteniendo el discurso del sujeto colectivo y fueron distribuidas en frecuencia absoluta y relativa. Ideas centrales similares entre profesores y estudiantes sobre el aprendizaje a distancia fueron: a) es adecuado para cursos didácticos; b) limitado para cursos de laboratorio y clínicos; c) presenta dificultades devido al acceso a Internet. Específicamente para profesores: a) complemento a la docencia en el aula; b) aumenta el estrés devido a la curva de aprendizaje con tecnologías digitales; c) dificultad para conciliar las clases con las actividades domésticas; d) preocupaciones con la motivación y la interacción con los estudiantes; e) las clases asincrónicas favorecen la fijación del conocimiento y las clases sincrónicas favorecen la interacción con los estudiantes; f) métodos de evaluación poco fiables; y g) preocupación por volver a las clases presenciales. Para los estudiantes: a) se aplicó a todos los cursos; b) desmotivador fundamental para orientar los estudios; c) compromiso de los profesores; d) conferencias largas; e) actividades escolares excesivas; f) difícil control y evaluación de asistencia; g) la comodidad de estar en casa; y h) impacto en la investigación. Profesores consideraron el aprendizaje a distancia como una oportunidad de aprendizaje sobre cómo utilizar las tecnologías digitales, pero demasiado limitado para las actividades de laboratorio y clínicas y la interacción con los estudiantes. Estudiantes lo encontraron desalentador debido a la ausencia de clases prácticas y al exceso de actividades escolares.

RESUMO

Introduction and Aims: The behavioral changes that arose from quarantine due to the COVID-19 pandemic may have impacted the weight of people. This study aims to investigate the incidence and predictors of weight gain during the quarantine period. Methods: An online survey was performed five months after the social distance measures implementation. Participants recorded their current and usual weight before lockdown. A multivariate logistic regression model was performed. Results: Data on 1334 participants were evaluated (33.6y, 79.8% females), and 58.8% have gained weight (3.0 kg; 0.1 to 30.0 kg). Predictors of weight gain were increased food intake (OR = 5.40); snacking (OR = 2.86); fast food (OR = 1.11); canned products (OR = 1.08); and in physical activity (OR = 0.99) concerning the period before the pandemic; also time spent at work, including household chores (OR = 1.58); evening snack (OR = 1.54); higher frequency of alcoholic beverage intake (OR = 1.59) and dose of alcoholic beverage (OR = 1.11); uncontrolled eating (OR = 1.01), and vegetable intake (OR = 0.92) during the quarantine and physical activity before pandemic period (OR = 0.99). Conclusion: Most participants have gained weight during the pandemic because of working changes, lifestyle, eating habits changes, and uncontrolled eating behavior. These results can be useful to encourage changes during future quarantine periods to prevent weight gain.

RESUMO

ABSTRACT: The objective of this study was to assess the use and experience with digital communication tools among dentistry professors and students to adapt to distance learning during the Covid-19 pandemic. Nine hundread and ninety five participants (479 dentistry professors and 516 students) from countries in North America, Latin America, Brazil, Europe, Asia, Oceania, and the Middle East answered a questionnaire about motivation/stress/anxiety; practice with digital technologies; synchronous/asynchronous communication technologies (difficulties/benefits), and which ones would they prefer using when returning to college. Data were analyzed by the Chi-square test and Fisher's exact (α=0.05). Motivation was more affected among the female professors, male students, and Brazilians (p<0.05). Concern about the academic future, was higher among female students, up to 30 years old, from Latin America and Brazil, and lower for European professors (p<0.05). Anxiety and stress were higher for undergraduate students up to 20 years old from Latin America and Brazil (p<0.05). European professors used more synchronous videoconferencing services for lectures/questions, while Brazilians used more text messaging applications for answering questions (p<0.05). Latin American professors used more surveys for evaluation (p<0.05). Brazilian professors indicated that they would use "online meetings" and "survey administration services" when returning to face-to-face activities and European professors/students would use "email" (p<0.05). Professors from Asia/Oceania/Middle East and professors/students from Brazil indicated "remote activities were important for students not to be inactive" (p<0.05). Efforts were made to adapt Dentistry's teaching to distance learning during the COVID-19 pandemic. However, the technologies used for this, feelings, and experiences differed between professors and students.

RESUMEN: El objetivo de este estudio fue evaluar el uso y la experiencia con herramientas de comunicación digital entre profesores y estudiantes de odontología para adaptarse al aprendizaje a distancia durante la pandemia Covid-19. Novecientos noventa y cinco participantes (479 profesores y 516 estudiantes de odontología) de países de diferentes regiones de América del Norte, América Latina, Brasil, Europa, Asia, Oceanía y Oriente Medio respondieron un cuestionario sobre motivación/ estrés/ansiedad; práctica con tecnologías digitales; tecnologías de comunicación sincrónicas/asincrónicas (dificultades/beneficios), y cuáles continuarían usando al regresar a la universidad. Los datos se analizaron mediante las pruebas Chi-cuadrado y exacta de Fisher (α=0,05). La motivación se vio más afectada entre las profesoras, estudiantes y brasileños (p<0,05). La preocupación por el futuro académico fue mayor entre las estudiantes, hasta los 30 años, de América Latina y Brasil, y menor para el profesorado europeo (p<0,05). El estrés fue mayor para el estudiantado de pregrado de Latinoamérica y Brasil hasta los 20 años (p<0.05). El profesorado europeo utilizó más servicios de videoconferencia sincrónica para clases y consultas, mientras que el brasileño utilizó más aplicaciones de mensajería de texto para consultas (p<0,05). El profesorado latinoamericano utilizó más encuestas para evaluación (p<0.05). El profesorado brasileño indicó que utilizaría "reuniones en línea" y "servicios de encuestas" cuando regresaran a la presencialidad, mientras que el profesorado/ estudiantado europeo utilizaría "correo electrónico" (p<0,05). El profesorado de Asia/ Oceanía/Medio Oriente y profesorado/estudiantado de Brasil indicó que "las actividades remotas eran importantes para que el estudiantado no estuviera inactivo" (p<0,05). Se relizaron esfuerzos para adaptar la enseñanza de la Odontología al aprendizaje a distancia durante la pandemia de COVID-19. Sin embargo, las tecnologías utilizadas y las experiencias difirieron entre profesores y estudiantes.

RESUMO

Objetivo: Determinar la relación de los factores sociodemográficos con el uso adecuado de las mascarillas y el distanciamiento social apropiado para evitar el contagio del SARS-CoV-2 en las personas que visitan el mercado n.º 2 de Surquillo (Lima, Perú). Materiales y métodos: Estudio cuantitativo, observacional, descriptivo, transversal y prospectivo comunitario. Se encuestó a 385 sujetos que acudieron al mercado de Surquillo entre septiembre y octubre del 2020 y se aplicó una lista de cotejo a los participantes. El tamaño muestral se obtuvo mediante EPIDAT 4.2 con una proporción esperada de prácticas inadecuadas del 50 %, nivel de confianza 95 % y precisión absoluta del 5 %. El muestreo fue no probabilístico por conveniencia. La información fue analizada mediante SPSS v25. Se aplicó estadística descriptiva y analítica usando prueba de X2 y regresión logística, con un nivel de confianza del 95 % y un p < 0,05. Resultados: El 48,80 % de los participantes fueron hombres. La edad promedio fue 42,61 ± 13,84 años. El 64,70% (n = 249) tuvo instrucción superior (técnico y universitario). El 47,50% (n = 183) de los encuestados procedía del distrito de Surquillo, y el 42,90 % (n = 165) fueron empleados independientes. El 48,80 % (n = 188) portaba una mascarilla en óptima condición. El 32,20 % (n = 124) cubría nariz y boca con un buen acople. La mascarilla de algodón fue la más usada: 35,10 % de los participantes (n = 135). El 70,00 % opinó que el distanciamiento debe ser de 1,5 m. Durante la observación, el 94 % mantuvo una distancia menor de 1,5 m. Existió una relación significativa entre el grado de instrucción superior y el uso adecuado de la mascarilla con p < 0,00, pero no para el distanciamiento social. Conclusiones: Existe una relación significativa entre el grado de instrucción y el uso adecuado de la mascarilla.

Objective: To determine the relationship that sociodemographic factors have with the proper use of masks and appropriate social distancing to prevent the spread of SARS-CoV-2 in people who attend the Surquillo No. 2 market (Lima, Peru). Materials and methods: A quantitative, observational, descriptive, cross-sectional and prospective community study. Both a survey and a checklist were administered to 385 subjects who attended the Surquillo market between September and October 2020. The sample size was obtained using Epidat 4.2 with an expected proportion of inadequate practices of 50 %, a confidence level of 95 % and an absolute precision of 5 %. Non-probability convenience sampling was used. The information was analyzed using IBM SPSS Statistics V25. Descriptive and analytical statistics were performed using the chi-square test and logistic regression with a confidence level of 95 % and p < 0.05. Results: Forty-eight point eight zero percent (48.80 %) of the research participants were males. Their mean age was 42.61 ± 13.84 years. Sixty-four point seven zero percent (64.70 %) (n = 249) had higher (technical and university) education, 47.50 % (n = 183) lived in Surquillo, 42.90 % (n = 165) were self-employed, 48.80 % (n = 188) wore a well-fitting mask in good condition, 32.20 % (n = 124) covered their nose and mouth properly, 35.10 % (n = 135) used cotton masks, 70.00 % thought that a distance of 1.5 m should be kept from others, and 94 % maintained a physical distance of less than 1.5 m during the observation. There was a significant relationship between the higher education level and the proper use of masks (p < 0.001) but not between the education level and social distancing. Conclusions: There is a significant relationship between the education level and the proper use of masks.

RESUMO

We assessed the associations of social distancing and mask use with symptomatic, laboratory-confirmed severe acute respiratory syndrome coronavirus 2 infection in Porto Alegre, Brazil. We conducted a population-based case-control study during April-June 2020. Municipal authorities furnished case-patients, and controls were taken from representative household surveys. In adjusted logistic regression analyses of 271 case-patients and 1,396 controls, those reporting moderate to greatest adherence to social distancing had 59% (odds ratio [OR] 0.41, 95% CI 0.24-0.70) to 75% (OR 0.25, 95% CI 0.15-0.42) lower odds of infection. Lesser out-of-household exposure (vs. going out every day all day) reduced odds from 52% (OR 0.48, 95% CI 0.29-0.77) to 75% (OR 0.25, 95% CI 0.18-0.36). Mask use reduced odds of infection by 87% (OR 0.13, 95% CI 0.04-0.36). In conclusion, social distancing and mask use while outside the house provided major protection against symptomatic infection.

RESUMO

OBJECTIVE: The present study's objective was to investigate the pandemic's impact on mental health and identify variables that can increase or decrease the chances of stress, anxiety, and depression, in both a sample with and one without self-reported mental health issues, in a Brazilian population. DESIGN: a cross-sectional quantitative study. Data were collected online in May and June of 2020. Participated 1130 adults between 18-78 years old (mean = 37.46 years, SD = 12.18), from 20 Brazilian states, with an average of 58.61 days (SD = 23.2) of social distancing. MAIN OUTCOME MEASURES: Depression, anxiety and stress symptoms, characterization of social distancing, and Coping strategies. RESULTS: A significantly higher prevalence of severe depression was found in those who practiced social distancing. Multinomial logistic regressions identified the explanatory model with risk and protection variables to mental health. For the group without a previous mental health diagnosis, using confrontation (OR = 1.39, CI95% 1.23-1.58) and escape strategies (OR = 1.48, CI95% 1.19-1.84) increases the odds of presenting severe depression, while positive reappraisal (OR = 0.85, IC95% 0.78-0.93) and problem-solving (OR = 0.75, CI95% 0.63--0.88) were protective factors. In the group with mental disorders, using confrontation (OR = 1.33, CI95% 1.10-1.60) and escape strategies (OR = 1.49, CI95% 1.12-1.98) were also risk factors for severe depression and no coping protective factors were found. CONCLUSIONS: Problem-solving and positive reappraisal were protective strategies that potentially reduced the odds of presenting depression and anxiety, but only in people without a previous mental health diagnosis. Public policies must offer psychological support to the most vulnerable, as well as orientation based on scientific evidence, aiming at improving quality of life.

RESUMO

Abstract Introduction The concept of social isolation is currently understood as a measure of epidemiological containment that aims to reduce the speed of spread of the disease, enabling health services to prepare their resources to cope with the likely increase in demand, while also seeking to provide additional protection to groups considered to be at higher risk. Objective The present narrative review aims to compile and synthesize the literature related to social isolation produced during the COVID-19 pandemic in 2020. Method This study is a narrative review of the literature on social isolation in the context of the COVID-19 pandemic. Results 73 publications were included for full-text reading and were classified into the following categories: levels of social isolation, economic effects, family relationships, health system, mental health of the population, and use of technology. Conclusions It is necessary to plan an escalation of responses to the consequences of the pandemic, especially in view of the increased demand on the health sector and social services. The negative effects of social isolation can be prevented by public policies that offer a response to the economic recession, maintenance of social work, encouragement of quality care in mental health services, and community support for vulnerable families.

RESUMO

From its very beginning, sociological thought has been concerned with a topic central to our daily lives: social distance. Since inception, the concept of social distance has referred to the relationships of familiarity and strangeness between social groups, which is experienced in the social world in terms of "We" and "They". This article covers the main tenets of a Schutzian phenomenological approach to the study of social distance and group relationships. Specific focus is placed on the different attitudes and valuations of the in-group towards the out-group considered as a stranger, the invisible excess of meaning that emerges in these types of social relationships and the conceptual construction of the Other that explains the phenomenon of discrimination.

RESUMO

COVID-19 is an acute respiratory illness with higher mortality in older adults. This condition is spread person-to-person through close contact, and among policies employed to decrease transmission are the improvement of hygiene habits and physical distancing. Although social distancing has been recognized as the best way to prevent the transmission, there are concerns that it may promote increased depression symptoms risk and anxiety, mainly in older adults. This cross-sectional study aimed to verify self-concept of social distancing in adults compared to older adults. All participants, over 18 years and residents of São Paulo state (Brazil), were invited to join this research study by a message application and answered an interdisciplinary questionnaire during the period from May 23 to June 23, 2020. The questions were divided into the following aspects: sociodemographic data, financial conditions, routine-related perception, perception of health, physical and emotional state, and eating habits. The younger adult group was composed of 139 participants, with a mean age of 43.15 years (±10.92), and the older adult group was composed of 437 participants with a mean age of 67.59 years (±6.13) of both sex. Changes in routine during the period of social distance were reported by 95% of adults and 96.8% of older adults, but adults indicated more significant alterations in routine. Although there was no difference between groups for several aspects, adults revealed greater alterations in sleep quality, evacuation frequency, and more difficulty to perform daily activities at home. Further studies are necessary to follow up the impacts of social distancing among adults and older adults in different socioeconomic contexts to better understand the long-term alterations and the necessity of interventions.

RESUMO

Abstract INTRODUCTION: This study evaluates the impact of social distancing on the spread of coronavirus disease (COVID-19). METHODS: Using data from the Brazilian Ministry of Health, we conducted an interrupted time series analysis to estimate the impact of lockdown on the number of daily cases of COVID-19 in Araraquara, São Paulo. RESULTS: Policy changes neutralized the positive trend of the disease. To provide more reliable evidence, we added two control cases from Araçatuba and São Carlos to the regression model, and the results remained consistent. CONCLUSIONS: Social distancing interventions are effective tools for flattening epidemic curves.

RESUMO

Objetivo: Descrever as medidas de contenção de tipo lockdown e a incidência da COVID-19 em sete países: África do Sul, Alemanha, Brasil, Espanha, Estados Unidos, Itália e Nova Zelândia. Métodos: Estudo ecológico descritivo, com dados da incidência diária dos casos confirmados de COVID-19 entre 22 de fevereiro e 31 de agosto de 2020, e informações sobre medidas de lockdown implementadas pelo governo de cada país. Resultados: Os países que implementaram lockdown tiveram diminuição da incidência diária de COVID-19 (casos por milhão de habitantes) no período de três semanas, a contar do início da medida: África do Sul (3,7 a 1,7), Alemanha (37,5 a 33,7), Espanha (176,3 a 82,0), Itália (92,0 a 52,1) e Nova Zelândia (7,5 a 1,7). O Brasil e os Estados Unidos, que não implementaram lockdown, não apresentaram uma diminuição considerável. Conclusão: Após a implementação de lockdown, houve uma diminuição considerável do número de casos confirmados.
