Objective: to analyze the frequency and associated risk factors for COVID-19 infection and the availability of Personal Protective Equipment used by primary healthcare workers., Method: a cross-sectional study was conducted over six months in Rio Grande do Sul. Descriptive analysis was performed, with the comparison of independent samples using Pearson's Chi-square test and Fisher's Exact test (p<.05)., Results: the study included 206 (27%) healthcare workers who presented COVID-19 symptoms. There was a statistical association for the following variables: availability of surgical masks (p=.003), seeking information on the correct use of personal protective equipment (p=.045), having attended people with flu-like syndrome (p=.024), and believing that the highest risk of contamination is when attending a patient positive for coronavirus disease (p=.001)., Conclusion: the availability of personal protective equipment is indispensable for COVID-19 prevention, with special emphasis on the use of surgical masks. Furthermore, the study highlighted the importance of providing Personal Protective Equipment in conjunction with guidance on its use., Highlights: (1) Highlighted impacts on the distribution of PPE necessary for worker safety.(2) Emphasized the need for training and education regarding the use of PPE.(3) Found significance regarding the availability of surgical masks.(4) Identified the need for further research on health safety topics.(5) Revealed a high incidence of symptomatic workers and positive cases of COVID-19.

Objective: To assess the association between household food insecurity (FI) and major depressive episodes (MDE) amid Covid-19 pandemic in Brazil., Design: Cross-sectional study carried out with data from four consecutive population-based studies., Setting: The study was conducted between May and June 2020, in Bagé, a Brazilian southern city. Household FI was measured using the short-form version of the Brazilian Food Insecurity Scale. Utilising the Patient Health Questionnaire-9, we used two different approaches to define MDE: the cut-off point of ≥ 9 and the diagnostic criteria proposed by the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR). Association between FI and MDE was analysed using crude and adjusted Poisson regression models., Participants: 1550 adults (≥ 20 years old)., Results: The prevalence of household FI was 29·4 % (95 % CI 25·0, 34·4). MDE prevalence varied from 4·4 % (95 % CI 3·1, 6·0), when we used the DSM-IV-TR criteria to define this condition, to 9·6 % (95 % CI 7·3, 12·5) of the sample, when we used the cut-off point of ≥ 9 as definition. The prevalence of MDE was more than two times higher in those individuals living with FI, independent of the criteria adopted to define the outcome. Adjustment for potential confounders did not change the association's magnitude., Conclusions: Household FI has been positively associated with MDE amid Covid-19 pandemic, independent of socio-demographic characteristics of participants. Actions are needed to warrant basic living conditions to avoid FI and hunger and its consequences for the Brazilian population, especially those consequences linked to mental health disorders.

Background: This study aims to investigate inequalities in leisure-time physical activity (PA) practice amid the COVID-19 pandemic in a southern Brazilian city., Methods: Four repeated population-based surveys were carried out. PA was collected using a questionnaire proposed by the authors and an adapted version of the leisure-time section of the International Physical Activity Questionnaire. The sociodemographic variables were sex, age, skin color, and education level. The participants also answered questions regarding social distancing measures compliance. Descriptive analyses based on proportions and their respective P values for categorical variables were presented. The chi-square test for heterogeneity and linear trend was used., Results: The sample is composed of 1556 individuals (66.1% female). Overall, between rounds 1 and 2, PA prevalence declined, followed by a gradual increase thereafter. PA practice during the pandemic was higher among men, individuals with higher education level, and individuals with white skin color in all rounds. In rounds 2, 3, and 4, PA was lower among individuals who were practicing more social distancing., Conclusion: To tackle the PA inequalities, policymakers and stakeholders need to confront disparities, defending greater availability of public policies that are attentive to inequalities, especially regarding gender, skin color, and educational level, to promote PA as a human right.

The objective was to analyze trends and inequalities in the prevalence of food insecurity during the COVID-19 pandemic according to sociodemographic factors and social distancing measures. We analyzed data from four serial epidemiological surveys on COVID-19 in May and June 2020, with adults and elderly living in Bagé, Rio Grande do Sul State, Brazil. Food insecurity was assessed with the short version of the Brazilian Food Insecurity Scale (EBIA), with the recall period adapted to the beginning of the social distancing period in the city. Sociodemographic characteristics and the adoption of social distancing measures were analyzed, and their associations with food insecurity were assessed with chi-square test. The temporal trend in food insecurity according to these characteristics was assessed via linear regression. Inequalities in food insecurity were assessed with the angular inequality index and concentration index. Of the 1,550 individuals studied, 29.4% (95%CI: 25.0; 34.4) presented food insecurity. Analysis of inequality showed higher concentration of food insecurity among the younger and less educated and those living with five or more residents in the same household. Over the course of the four surveys, prevalence of food insecurity decreased most sharply among the younger, those living in households with up to two residents, and those with two or more workers. There was a strong association between food insecurity and sociodemographic factors, which may indicate the pandemic´s potential economic impact on households' food situation.
