Overweight and associated factors in Basic Education teachers during the Covid-19 pandemic: gender differentials / Excesso de peso e fatores associados entre professores da Educação Básica durante a pandemia de Covid-19: diferenciais de sexo

ABSTRACT Objective To estimate the prevalence of overweight among teachers in Minas Gerais during the Covid-19 pandemic and to review relevant gender associated factors. Methods Cross-sectional and analytical study, websurvey type, carried out with 15,641 teachers of public Basic Education in Minas Gerais, Brazil. Data collection took place from August to September 2020 with the use of a digital form. The dependent variable was overweight, calculated by the body mass index using the teachers' self-reported weight and height. Poisson regression was used, with robust variance. Results Among the participating teachers, 52.4% were overweight. When stratified by gender, 51.1% women and 58.2% men were considered overweight, with a significant difference between them (p<0.001). There was a higher prevalence of overweight among women in the age group of 30 to 59 years (PR=1.39) and in women 60 years or older (PR=1.45) living in the metropolitan region of the state (PR=1.06) who had children (PR=1.19), who were not exercising (PR=1.09) and with a worse dietary pattern during the pandemic (PR=1.12), much afraid of Covid-19 (PR=1.04) and with anxiety and/or depression during the pandemic (PR=1.14). Among men, there was a higher prevalence of overweight among those individuals aged 30 to 59 years (PR=1.19), who lived with a spouse (PR=1.15) working more than 40 hours per week (PR=1.12) and those with the worst dietary pattern during the pandemic (PR=1.10). Conclusion The results showed a 52.4% prevalence of overweight teachers and different associated factors between the genders.

RESUMO Objetivo Estimar a prevalência de excesso de peso entre professores de Minas Gerais durante a pandemia de Covid-19 e analisar os fatores associados segundo o sexo. Métodos Estudo transversal e analítico, do tipo websurvey, realizado com 15.641 professores da educação básica pública de Minas Gerais, Brasil. A coleta de dados ocorreu de agosto a setembro de 2020, via formulário digital. A variável dependente foi o excesso de peso, calculado pelo índice de massa corporal através do peso e altura autorreferidos pelos professores. Utilizou-se a Regressão de Poisson, com variância robusta. Resultados Entre os professores participantes, 52,4% estavam com excesso de peso. Quando estratificado por sexo, 51,1% das mulheres e 58,2% dos homens estavam com excesso de peso, apresentando diferença significativa entre eles (p<0,001).

Increased vulnerability to SARS-CoV-2 infection among indigenous people living in the urban area of Manaus.

The COVID-19 pandemic threatens indigenous peoples living in suburban areas of large Brazilian cities and has thus far intensified their pre-existing socio-economic inequalities. We evaluated the epidemiological situation of SARS-CoV-2 infection among residents of the biggest urban multiethnic indigenous community of the Amazonas state, Brazil. Blood samples of 280 indigenous people living in the surrounding area of Manaus were tested for the presence of anti-SARS-CoV-2 IgA or IgG antibodies. The risk factors and sociodemographic information were assessed through an epidemiological questionnaire. We found a total positivity rate of 64.64% (95% CI 59.01-70.28) for SARS-CoV-2 infection. IgA and IgG were detected in 55.71% (95% CI 49.89-61.54) and 60.71% (95% CI 54.98-66.45) of the individuals, respectively. Over 80% of positive individuals were positive for both IgA and IgG.No significant difference in positivity rates between genders or age groups was observed. Moreover, the age group ≥ 60 years old showed the highest antibody ratios (IgA mean ratio = 3.080 ± 1.623; IgG mean ratio = 4.221 ± 1.832), while the age groups 13-19 and 20-29 showed the lowest IgA (mean ratio = 2.268 ± 0.919) and IgG ratios (mean ratio = 2.207 ± 1.246), respectively. Individuals leaving the home more frequently were at higher risk of infection (Odds ratio (OD) 2.61; 95% CI 1.00-1.49; p = 0.048). Five or more individuals per household increased fivefold the risk of virus transmission (OR 2.56; 95% CI 1.09-6.01; p = 0.019). The disproportionate dissemination of SARS-CoV-2 infection observed among the study population might be driven by typical cultural behavior and socioeconomic inequalities. Despite the pandemic threat, this population is not being targeted by public policies and appears to be chronically invisible to the Brazilian authorities.

Comparing COVID-19 risk factors in Brazil using machine learning: the importance of socioeconomic, demographic and structural factors.

The COVID-19 pandemic continues to have a devastating impact on Brazil. Brazil's social, health and economic crises are aggravated by strong societal inequities and persisting political disarray. This complex scenario motivates careful study of the clinical, socioeconomic, demographic and structural factors contributing to increased risk of mortality from SARS-CoV-2 in Brazil specifically. We consider the Brazilian SIVEP-Gripe catalog, a very rich respiratory infection dataset which allows us to estimate the importance of several non-laboratorial and socio-geographic factors on COVID-19 mortality. We analyze the catalog using machine learning algorithms to account for likely complex interdependence between metrics. The XGBoost algorithm achieved excellent performance, producing an AUC-ROC of 0.813 (95% CI 0.810-0.817), and outperforming logistic regression. Using our model we found that, in Brazil, socioeconomic, geographical and structural factors are more important than individual comorbidities. Particularly important factors were: The state of residence and its development index; the distance to the hospital (especially for rural and less developed areas); the level of education; hospital funding model and strain. Ethnicity is also confirmed to be more important than comorbidities but less than the aforementioned factors. In conclusion, socioeconomic and structural factors are as important as biological factors in determining the outcome of COVID-19. This has important consequences for policy making, especially on vaccination/non-pharmacological preventative measures, hospital management and healthcare network organization.

Brazil: hate and intolerance in times of pandemic in a mixed-race country.

This paper intends to analyse the current political and social situation in Brazil and show how this context has influenced the management of the public health crisis generated by the COVID-19 pandemic. To this end, the authors conducted an investigation into Brazil's historical roots, which have not only engendered deep class differences but, also, social psychopathologies such as dissociation and perversion. Finally, this paper presents a symbolic analysis of social exclusion and how the mythical figure of Sophia can inspire a renewed movement of inclusion and tolerance.

Cet article se propose d'analyser la situation politique et sociale actuelle au Brésil et de montrer comment ce contexte a influencé la gestion de la crise sanitaire publique générée par la COVID-19. Dans ce but, les autrices ont conduit une enquête approfondie sur les racines historiques du Brésil, racines qui ont engendré non seulement de profondes différences de classes mais également des psychopathologies sociales, telles la dissociation et la perversion. Cet article présente en conclusion une analyse symbolique de l'exclusion sociale et montre comment le personnage mythique de Sophia peut inspirer un mouvement renouvelé d'inclusion et de tolérance.

Sleep during COVID-19 lockdown: A cross-cultural study investigating job system relevance.

Our study aimed to assess the change in the sleep patterns during the Coronavirus lockdown in five regions (Austria/Germany, Ukraine, Greece, Cuba and Brazil), using online surveys, translated in each language. Part of the cohort (age 25-65, well-educated) was collected directly during lockdown, to which retrospective cross-sectional data from and after lockdown (retrospective) questionnaires were added. We investigated sleep times and sleep quality changes from before to during lockdown and found that, during lockdown, participants had (i) worse perceived sleep quality if worried by COVID-19, (ii) a shift of bedtimes to later hours during workdays, and (iii) a sleep loss on free days (resulting from more overall sleep during workdays in non-system relevant jobs), leading to (iv) a marked reduction of social jetlag across all cultures. For further analyses we directly compared system relevant and system irrelevant jobs, because it was assumed that the nature of the lockdown's consequences is dependent upon system relevance. System relevant jobs were found to have earlier wake-up times as well as shorter total sleep times on workdays, leading to higher social jetlag for people in system relevant jobs. Cultural differences revealed a general effect that participants from Greece and Ukraine had later bedtimes (on both work and free days) and wake-up times (on workdays) than Cuba, Brazil and Austria, irrespective of COVID-19 lockdown restrictions.

Covid-19 pandemic and the motivations for demanding health service in indigenous villages.

OBJECTIVE: To discuss the fundamental aspects in the establishment of preventive measures to tackle covid-19 among indigenous people in view of the motivations for seeking health care in villages of the Terra Indígena Buriti, Mato Grosso do Sul, Brazil. METHODS: Theoretical-reflective study based on assumptions of the National Health System and previous ethnographic research that enabled the identification of the motivations to seek health care in Buriti villages. RESULTS: Indigenous people seek health centers for health care programs assistance, treatment of cases they cannot resolve and to chat. Such motivations were the basis for discussing the indigenization process in the confrontation of the new coronavirus pandemic in indigenous lands. FINAL CONSIDERATIONS: The motivations for seeking health care show the physical and social vulnerability of the Terena ethnicity. The effectiveness of the social isolation measure in the villages depends on the dialogue with indigenous leaders, professional engagement and intersectoral actions.
