This paper employs structural topic modeling (STM) to describe the academic philosophy landscape in Brazil. Based on a public national database, a corpus consisting of 12,515 abstracts of monographs defended in philosophy graduate programs between 1991 and 2021 was compiled. The final STM model identified 74 meaningful research topics, clustered into 7 thematic categories. This study discusses the prevalence of the most significant topics and categories, their trends across three decades, and their (positive or negative) association with the supervisor's gender. Results show the first empirical evidence that Brazilian philosophical research exhibits a greater focus on philosophers than on specific themes or problems. Moreover, by visualizing the variations in topic prevalence over time, it was possible to track the rise or decline of the major interest categories and topics. Finally, results also show which topics are more influenced or less influenced by gender. [ABSTRACT FROM AUTHOR]

Objective: To analyse the direct and indirect associations of experience of racial discrimination on dietary patterns (DP), obesity and abdominal obesity. Design: This is a cross-sectional population-based study. The main exposure was self-reported experiences of racial discrimination (Experiences of Discrimination scale). The mediator variables were the DP: healthy, Brazilian traditional, sugar and carbohydrates, and fast food. The outcomes were obesity (BMI ≥ 30 kg/m2) and abdominal obesity (waist circumference ≥ 88 cm for women; ≥ 102 cm for men). Structural equation modelling was applied. Setting: Porto Alegre, Brazil. Participants: Totally, 400 adults aged between 20 and 70 years were participated. Results: The mean age of participants was 47·2 years (sd = 13·9), and 75 % were women. Experiencing racial discrimination had a positive direct effect on obesity (healthy DP: β = 0·153, P < 0·05; Brazilian DP: β = 0·156, P < 0·05; sugar and carbohydrates DP: β = 0·156, P < 0·05; and fast-food DP: β = 0·153, P < 0·05) and abdominal obesity (healthy DP: β = 0·206, P < 0·01; Brazilian DP: β = 0·210, P < 0·01; sugar and carbohydrates DP: β = 0·204, P < 0·01; and fast-food DP: β = 0·204, P < 0·01). The experience of racial discrimination did not have a direct effect on DP, nor did it exert an indirect effect on obesity and abdominal obesity through any DP. Conclusions: A higher experience of racial discrimination is associated with obesity and abdominal obesity, independent of diet. [ABSTRACT FROM AUTHOR]

Context There is no systematic review on the relationship between racial discrimination and eating habits. Objective A systematic review was conducted to synthesize evidence on the association between perceived racial discrimination (PRD) and eating habits. A conceptual model was developed to depict the most common mechanisms used to explain this association. Data Sources Articles were retrieved from the PubMed, Embase, LILACS, and PsycINFO databases from inception to January 2021. Study Selection Only observational studies were included, and there were no restrictions on age, racial group, or country. Two reviewers selected the articles independently. Data Extraction Data were extracted independently by 2 reviewers. The assessment of methodological quality was conducted using the Newcastle-Ottawa Scale. Results All studies retrieved were conducted among the US population. Nineteen studies were included. On average, the studies showed a methodological quality of 66%. Forty-six associations were evaluated: 38 between PRD and negative eating habits, 29 between PRD and eating behavior, and 17 between PRD and food consumption. Conclusions PRD negatively affects eating habits. A conceptual framework based on ecosocial theory is suggested as a guide for future research. Further studies in different countries (beyond the United States) should be conducted to understand how racial discrimination affects eating habits within different ethnic, cultural, social, and economic contexts.

The aim of this paper is the clarification of some key concepts of the methodology of biographical narratives. Despite of the fact that this methodology is widely used, its theoretical underpinnings not yet appear to have been systematically compiled. Accordingly, the objectives of this paper are as follows: [i] develop the method of narrative interview and the method of analysis of biographical narratives created by Fritz Schütze; [ii] clarify some of the theoretical points that this author assumes (as the task of sociology and its object of study) through the concepts of self, society and language; and [iii] explore the influences of the theoretical framework of the phenomenological sociology of Alfred Schutz and compare both authors. Its conclusion is the statement that the phenomenological sociology cannot be considered the only theoretical framework that underlies Schütze's methodology, which points out to new questions.

Background: Racial discrimination is linked to unhealthy food environments and a higher prevalence of food insecurity. However, no study has explored their interrelated effects. We analyzed the relationship between racial discrimination, community food environment, and food insecurity in adults of different socioeconomic status. We also investigated the potential modifying effect of the food environment on the relationship between racism and food insecurity. Methods: This was a cross-sectional study of 400 adults aged 20–70 years residing in the central area of ​​Porto Alegre, the capital of Rio Grande do Sul state. Race and racial discrimination were assessed by self-reported race/skin color using the Experiences of Discrimination scale (EOD), respectively. The food environment was assessed using the Nutrition Environment Measures Survey in Stores (NEMS-S) tool. Food insecurity was assessed using the short version of the Brazilian Food Insecurity Scale (EBIA for short, in Portuguese). Poisson regression with robust variance was employed for the multivariate analysis. Results: The prevalence of food insecurity was higher in areas with a poorer food environment (areas 1 and 3; 56.6% and 58.8%, respectively). Racial discrimination was associated with food insecurity, where every 1-point increase in the racial discrimination score increased the likelihood of food insecurity by 7% (prevalence ratio [PR] 1.07; 95% CI, 1.03–1.20). When stratifying the analyses by food environment, racial discrimination was associated with food insecurity only in areas with a poorer food environment (PR 1.06; 95% CI, 1.01–1.10). Conclusions: Experiences of racial discrimination were associated with a higher prevalence of food insecurity in the study population. The community food environment was an effect modifier of this relationship, highlighting the relevance of interventions in the food environment focused on areas with a greater presence of Black people as a way of combating racism and food insecurity.

The prevalence of overweight in Brazilian adults has grown in recent years. There is evidence indicating that environmental factors, especially social characteristics, may be involved in the aetiology of overweight, but few studies have investigated this association adequately. The main objective of this study was to identify residents' perception of their social environment (social cohesion, security and violence) and assess its relationship with overweight in a central area of Porto Alegre, Brazil. The associations between socioeconomic characteristics and social environment perception were also explored. This cross-sectional study conducted in 2018-19 had 400 participants aged from 20 to 70 years living in low- and high-income areas of the city of Porto Alegre. Participants' perception of social cohesion, security and violence were evaluated using a validated questionnaire. Participants' body mass index (BMI) was measured, and those with a BMI ≥25 kg/m2 were considered to be overweight. Unadjusted and adjusted prevalence ratios (PRs) and 95% confidence intervals (95% CIs) were estimated through Poisson regression analysis; level of significance was 5%. The prevalence of overweight in the sample was 68.8% (95% CI 64.0-73.2). Individuals with a more positive social cohesion perception had a higher prevalence of overweight (PR 1.06; 95% CI: 1.00-1.12; p=0.02) than those with a less positive perception. Brown individuals also had a higher prevalence of overweight (PR: 1.08; 95% CI: 1.02-1.15; p=0.03) than those of other skin colour/race. No association was found between overweight and perception of security or violence. Therefore, social cohesion may be an important factor in overweight and the findings highlight the importance of considering social factors, and their perceptions, when planning actions for the prevention and control of overweight in a population.

Introduction: Climate conditions may influence the transmission of COVID-19. Thus, the aim of this study was to evaluate the impact of temperature and relative humidity on COVID-19 cases and related deaths during the initial phase of the epidemic in Brazil. Methodology: An ecological study based on secondary data was conducted. Daily data on new COVID-19 cases, deaths, and climate indicators were collected from February 20 to April 18, 2020 (n = 59 days) for all state capital cities in Brazil and the Federal District (Brasília). The climate indicators included mean temperature, temperature amplitude, mean relative humidity, relative humidity amplitude, and percentage of days with mean relative humidity = 65 %. Correlation and multiple linear regression analyses were performed for all cities and stratified by quintiles of the COVID-19 incidence rate. Results: The mean daily temperature was positively correlated with the number of days until the first COVID-19 case was reported. A lower mean relative humidity was correlated with a lower number of cases and deaths in Brazil, especially when the relative humidity was = 65 %. Higher temperatures and humidity amplitudes were correlated with lower COVID-19 mortality. Additionally, after controlling for humidity, cumulative cases of COVID-19 were inversely associated with temperature in cities with mean temperatures less than 25.8 °C. Conclusions: Variations in temperature and humidity across the Brazilian territory may have influenced the spread of the novel coronavirus during the initial phase of the epidemic.
