Exposure and power of TV food advertising during the COVID-19 pandemic in Brazil: a content analysis.

BACKGROUND: With the COVID-19 pandemic and the restrictions imposed to contain the spread of SARS-CoV-2, the Brazilian population has increased the time spent at home and watching television (TV). Since food advertising exposure is a key driver of food choices, this study described the content of food advertisements (ads) on Brazilian TV during the COVID-19 pandemic. METHODS: This is an exploratory study. A total of 684 h of TV programming comprised of three free-to-air channels and two pay-per-view channels was recorded from 06 a.m. to 12 a.m. for eight non-consecutive days in June 2020. A content analysis of all the food-related ads was carried out. The data collection process followed INFORMAS Protocol for TV food advertising monitoring. RESULTS: The sample was composed of 7,083 ads, 752 (10.6%) of which were food-related and 487 (6.9%) were promoting ultra-processed foods. The content analysis indicated seven thematic categories, all of them with reference to the COVID-19 pandemic: brand and product differentials (79.8%); visual and sound effects (70.2%); thematic campaigns (56.0%); digitization (22.9%); convenience (16.5%); economic benefits (11.9%); and commensality and social interaction (6.1%). Ads content varied according to the day of the week, the time of the day, the length of the ad, and the channel type. CONCLUSIONS: The thematic of food advertising on Brazilian TV during the COVID-19 pandemic is aligned with the country's health crisis context and varied during the programming.

Sodium intake according to NOVA food classification in Brazil: trends from 2002 to 2018.

Excessive sodium intake is a major global public health issue and the identification of dietary sources and temporal trends in its consumption are a key to effective sodium reduction policies. This study aims to update estimates of sodium intake and its dietary sources in Brazil according to the NOVA food classification system. Records of 7-day food purchases of households from the Brazilian Household Budgets Survey of 2002-2003, 2008-2009, and 2017-2018 were converted into nutrients using food composition tables and the mean availability was estimated per 2,000kcal/day. Mean daily sodium available for consumption in Brazilian households has increased from 3.9 to 4.7g per 2,000kcal, from 2002-2003 to 2017-2018, over twice the recommended levels of sodium intake. From 2002-2003 to 2017-2018, the processed culinary ingredients, including table salt, represented the largest dietary source of sodium, although their participation in dietary sodium was reduced by 17% (66.6% to 55%), while the percentage of dietary sodium from processed foods increased by 20.3% and from ultra-processed foods increased by 47.6% (11.3% to 13.6% and 17% to 25.1%, respectively). In conclusion, the total household sodium availability remains high and has increased over time in Brazil, yet the participation of different dietary sources of sodium have gradually changed.

Revolutionising food advertising monitoring: a machine learning-based method for automated classification of food videos.

OBJECTIVE: Food advertising is an important determinant of unhealthy eating. However, analysing a large number of advertisements (ads) to distinguish between food and non-food content is a challenging task. This study aims to develop a machine learning-based method to automatically identify and classify food and non-food ad videos. DESIGN: Methodological study to develop an algorithm model that prioritises both accuracy and efficiency in monitoring and classifying advertising videos. SETTING: From a collection of Brazilian television (TV) ads data, we created a database and split it into three sub-databases (i.e. training, validation and test) by extracting frames from ads. Subsequently, the training database was classified using the EfficientNet neural network. The best models and data-balancing strategies were investigated using the validation database. Finally, the test database was used to apply the best model and strategy, and results were verified with field experts. PARTICIPANTS: The study used 2124 recorded Brazilian TV programming hours from 2018 to 2020. It included 703 food ads and over 20 000 non-food ads, following the protocol developed by the INFORMAS network for monitoring food marketing on TV. RESULTS: The results showed that the EfficientNet neural network associated with the balanced batches strategy achieved an overall accuracy of 90·5 % on the test database, which represents a reduction of 99·9 % of the time spent on identifying and classifying ads. CONCLUSIONS: The method studied represents a promising approach for differentiating food and non-food-related video within monitoring food marketing, which has significant practical implications for researchers, public health policymakers, and regulatory bodies.

Availability and price of fruits and vegetables in the surroundings of food and nutrition public establishments.

BACKGROUND: Inequalities of access to healthy food reinforce the need to strengthen public policies on Food and Nutritional Security. In this context, Food and Nutrition Public Establishments, which are public spaces for distribution and commercialization of healthy foods, stand out. However, in middle-income countries there is little monitoring of the impacts of public policies on food environments, which are fundamental for strengthening these actions. Thus, the purpose of the study was to evaluate the availability and price of fruits and vegetables in areas with and without Food and Nutrition Public Establishments. METHODOLOGY: A cross-sectional study carried out in Belo Horizonte, Brazil. Audits were conducted in the retail food environment of a representative sample of Food and Nutrition Public Establishments (n = 10) and corresponding census sectors, without Food and Nutrition Public Establishments (n = 10). Information was collected on the availability and price of the most consumed fruits and vegetables in Belo Horizonte. The food retailers were grouped into fresh food retailers and mixed food retailers. The Chi-Square test was used to compare the availability of fruits and vegetables between areas. The Mann Whitney test was used to compare the prices of fruit and vegetables and the price differences between fresh food retailers and mixed food retailers between areas. RESULTS: 148 food retailers were audited, including 17 Food and Nutrition Public Establishments. In fresh food retailers, the availability of vegetables was higher in areas with Food and Nutrition Public Establishments (p = 0.024). In mixed food retailers there was low availability of fruit and vegetables in both areas (34.0% vs. 26.2%; p>0.05). The price difference between fresh food retailers and mixed food retailers differed significantly between areas (p<0.001). In general, fresh food retailers had lower prices than mixed food retailers only in areas with Food and Nutrition Public Establishments. CONCLUSIONS: The presence of Food and Nutrition Public Establishments was associated with the availability of vegetables, and with lower prices in fresh food retailers compared with mixed food retailers. Monitoring and understanding the impacts of public policies on the food environment are essential to register trends and provide relevant information to civil society and government authorities.

Leisure time physical activity among older adults in Brazil: a time series analysis of a population-based survey (2009-2020).

The practice of leisure time physical activity brings several health benefits, such as the prevention of noncommunicable diseases. Investigating the temporal trend of physical activity practice in older adults by sociodemographic characteristics and geographical regions could be important to plan public health policies and effective interventions. This is a time series study that analyzes the temporal trend of leisure time physical activity among Brazilian older adults with data from 2009 to 2020. For this, we used a sample of 186,097 older adults (≥ 60 years old) obtained from the Risk and Protective Factors Surveillance System for Chronic Noncomunicable Diseases Through Telephone Interview (Vigitel) (2009-2020). Information on leisure time physical activity and sociodemographic and health characteristics were collected. Prais-Winsten regression was used to identify significant trends in the annual variation of the leisure time physical activity indicators. Practice of ≥ 150 minutes/week of moderate intensity leisure time physical activity varied from 23.3% to 27.5% (0.41p.p./year) (2009-2020), with a higher increase during 2015-2020 (0.59p.p./year). The increase in the most recent period occurred among men, aged from 60 to 69 years, with lower educational level, residing in the Northeast Region, and without self-reported chronic diseases. These results may contribute to the evaluation of Brazilian health policies targeting the leisure time physical activity practice in older adults.

Changes in dietary markers during the covid-19 pandemic in Brazil.

OBJECTIVE: Evaluate changes in the Brazilian population's diet and its determinants during the covid-19 pandemic. METHODS: We used diet data collected by the Datafolha Institute in 2019 (n = 1,384), 2020 (n =1,214), and 2021 (n = 1,459) from independent and representative samples of the adult population (aged 18 to 55 years) from all socioeconomic classes and geographic regions of Brazil. Food consumption was measured by checking the consumption of 22 sets of food on the day before the survey. The third cycle also included questions about changes in eating habits during the pandemic. We estimated the prevalence of consumption of the food sets in each cycle of the survey and used statistical tests for comparisons of proportions between the three cycles. RESULTS: Between 2019 and 2020, we observed a significant increase in the consumption of cereals, milk, packaged snacks or salty cookies, and industrialized sauces, as opposed to a decrease in the consumption of eggs. Between 2019 and 2021 and between 2020 and 2021, on the other hand, there was a significant decrease in the consumption of cereals, vegetables, fruits, and industrialized fruit juices and an increase in the consumption of soda, sweets, cookies, sausages, industrialized sauces, and ready meals. When asked about the main changes in the purchase and preparation of meals, 46.3% of the respondents reported consuming more food prepared at home during the pandemic. Regarding changes in eating habits, 48.6% of the respondents reported a change in their eating habits during the pandemic. The main reasons for such changes were greater concern with health (39.1%) and self-reported decreased family income (30.2%). CONCLUSIONS: The covid-19 pandemic had a negative impact on the diet of the population, and increased consumption of ultra-processed foods was reported for that period.

Impact of implementation of front-of-package nutrition labeling on sugary beverage consumption and consequently on the prevalence of excess body weight and obesity and related direct costs in Brazil: An estimate through a modeling study.

RATIONALE: Intake of sugary beverages has been associated with obesity and chronic non-communicable diseases, thereby increasing the direct health costs related to these diseases. Front-of-package nutrition labeling (FoPNL) aims to help consumers understand food composition, thereby improving food choices and preventing the development of such diseases. OBJECTIVE: To estimate, over five years, the impact of implementing FoPNL in Brazil on the prevalence of excess body weight and obesity in adults who consume sugary beverages and the direct costs related to such problems. METHODS: A simulation study to performed to estimate the effect of FoPNL implementation on the prevalence of excess body weight and obesity. The VIGITEL research database (2019), published in the 2020 report, was used in this study (the final sample consisted of 12,471 data points representing 14,380,032 Brazilians). The scenarios were considered: base (trend in sugary beverage intake); 1 (base scenario associated with the changes in energy content of the purchased beverages observed after the first phase of the Chilean labeling law (-9.9%); and 2 (scenario 1 associated with reformulation of beverages, total energy reduction of -1.6%). Changes in body weight were estimated using the simulation model of Hall et al. (2011) over five years. A linear trend in the prevalence of obesity and excess body weight in the Brazilian population was considered. The impact of the prevalence of obesity and excess body weight on body mass index was estimated. In addition, the direct health costs related to obesity were estimated. RESULTS: Energy consumption from sugary beverages after FoPNL implementation is expected to be reduced by approximately 28 kcal/day (95% CI, -30 to -27) considering scenario 1. In scenarios 1 and 2, without FoPNL, the prevalence of obesity and excess body weight over five years was estimated to be 25.3% and 25.2%, and 64.4% and 64.2%, respectively. By extrapolating the results to the entire Brazilian population, it was observed that the implementation of FoPNL may reduce the prevalence of obesity by -0.32 percentage points and -0.35 percentage points (scenario 1 and 2, respectively) and excess body weight by -0.42 percentage points and -0.48 percentage points (scenarios 1 and 2, respectively) in five years. It is estimated that after five years of implementation, it will be possible to save approximately US$ 5,5 millions (95% CI 4,7 to 8,8) in scenario 1, reaching approximately US$ 6,1 millions (95% CI 5,3 to 9,8) in scenario 2. CONCLUSION: The results of this modeling study indicate that FoPNL may reduce prevalence of excess body weight and obesity, representing strategic public policies for obesity prevention.

Nova diet quality scores and risk of weight gain in the NutriNet-Brasil cohort study.

OBJECTIVE: To assess the prospective association of two diet quality scores based on the Nova food classification with BMI gain. DESIGN: The NutriNet-Brasil cohort is an ongoing web-based prospective study with continuous recruitment of participants aged ≥ 18 years since January 2020. A short 24-h dietary recall screener including 'yes/no' questions about the consumption of whole plant foods (WPF) and ultra-processed foods (UPF) was completed by participants at baseline. The Nova-WPF and the Nova-UPF scores were computed by adding up positive responses regarding the consumption of thirty-three varieties of WPF and twenty-three varieties of UPF, respectively. Participants reported their height at baseline and their weight at both baseline and after approximately 15 months of follow-up. A 15-month BMI (kg/m2) increase of ≥5 % was coded as BMI gain. SETTING: Brazil. PARTICIPANTS: 9551 participants from the NutriNet-Brasil cohort. RESULTS: Increasing quintiles of the Nova-UPF score were linearly associated with higher risk of BMI gain (relative risk Q5/Q1 = 1·34; 95 % CI 1·15, 1·56), whereas increasing quintiles of the Nova-WPF score were linearly associated with lower risk (relative risk Q5/Q1 = 0·80; 95 % CI 0·69, 0·94). We identified a moderate inverse correlation between the two scores (-0·33) and a partial mediating effect of the alternative score: 15 % for the total effect of the Nova-UPF score and 25 % for the total effect of the Nova-WPF score. CONCLUSIONS: The Nova-UPF and Nova-WPF scores are independently associated with mid-term BMI gain further justifying their use in diet quality monitoring systems.

Health characteristics and behaviors associated with self-reported depression among Brazilian reproductive-aged women: Data from a population-based survey (2020-2021).

This cross-sectional study aimed to evaluate the health characteristics and behaviors associated with depression in a large probabilistic sample of Brazilian reproductive-aged women. A total of 11,698 non-pregnant women aged 18-49 years old from the 26 Brazilian capitals and Federal District were interviewed by landline between 2020 and 2021. Logistic regression models were used to estimate the Odds Ratio (OR) of health characteristics and behaviors (smoking, alcohol abuse, physical activity, regular intake of fruits and vegetables, overweight, obesity and poor self-rated health) according to the presence of depression and drug treatment for depression. Medical diagnosis of depression, and other health characteristics and behaviors were self-reported. Analyses were adjusted by age, race/skin color, education, and marital status. Prevalence of self-reported depression was 13.3% and drug treatment for depression was reported by 5.3% of the total studied population. The presence of self-reported depression was associated with smoking (adjusted OR - aOR 2.15; CI95%:1.44-3.20), regular intake of fruits and vegetables (aOR 0.75; CI95%:0.59-0.95), overweight (aOR 1.38; CI95%:1.10-1.71), obesity (aOR 1.34; CI95%:1.04-1.71) and poor self-rated health (aOR 4.34; CI95%:3.04-6.21). Drug treatment for depression was associated with smoking (aOR 2.29; CI95%:1.33-3.95), overweight (aOR 1.65; CI95%:1.18-2.30) and poor self-rated health (aOR 4.20; CI95%:2.59-6.83). Self-reported depression and drug treatment for depression were associated with unfavorable health characteristics and behaviors among reproductive-aged women in Brazil.

Temporal Trend in the Coexistence of Risk Behaviors for Noncommunicable Diseases in Brazil: 2009-2019.

INTRODUCTION: Individuals can accumulate multiple risk factors for noncommunicable diseases, increasing the chance of adverse health outcomes. We aimed to analyze the temporal trend in the coexistence of risk behaviors for noncommunicable diseases and their association with sociodemographic characteristics among adults in Brazil from 2009 through 2019. METHODS: This cross-sectional study and time-series analysis was based on data collected by the Surveillance System for Risk Factors and Protection for Chronic Diseases by Telephone Survey (Vigitel) from 2009 through 2019 (N = 567,336). We used item response theory to identify the coexistence of risk behaviors (infrequent consumption of fruits and vegetables, regular consumption of sugar-sweetened beverages, smoking, abusive alcohol consumption, insufficient leisure-time physical activity). We used Poisson regression models to assess the temporal trend in the prevalence of the coexistence of noncommunicable disease-related risk behaviors and associated sociodemographic characteristics. RESULTS: Risk behaviors that most contributed to the occurrence of coexistence were smoking, consumption of sugar-sweetened beverages, and alcohol abuse. Coexistence was more frequent among men and was inversely associated with age and education level. During the study period, we found a significant decrease in coexistence (adjusted prevalence ratio decreased from 0.99 in 2012 to 0.94 in 2019; P = .001), especially before 2015 (adjusted prevalence ratio = 0.94; P = .001). CONCLUSION: We found a reduction in the frequency of the coexistence of noncommunicable disease-related risk behaviors and their association with sociodemographic characteristics. It is necessary to implement effective actions to reduce risk behaviors, especially behaviors that lead to a greater coexistence of those behaviors.

Social Vulnerability of Brazilian Metropolitan Schools and Teachers' Absence from Work Due to Vocal and Psychological Symptoms: A Multilevel Analysis.

Teachers' voices and psychological symptoms are the main reasons for absence from work. The objectives of this study were: (i) to spatially represent, through a webGIS, the standardized rates of teachers' absences due to voice (outcome 1) and psychological symptoms (outcome 2) in each Brazilian Federative Unit (FU = 26 states plus Federal District) and (ii) to analyze the relationship between each national outcome rate and the Social Vulnerability Index (SVI) of the municipality where urban schools are located, adjusted for sex, age, and working conditions. This cross-sectional study comprised 4979 randomly sampled teachers working in basic education urban schools, of which 83.3% are women. The national absence rates were 17.25% for voice symptoms and 14.93% for psychological symptoms. The rates, SVI, and school locations in the 27 FUs are dynamically visualized in webGIS. The multilevel multivariate logistic regression model showed a positive association between voice outcome and high/very high SVI (OR = 1.05 [1.03; 1.07]), whereas psychological symptoms were negatively associated with high/very high SVI (OR = 0.86 [0.85 0.88]) and positively associated with intermediate SVI (OR = 1.15 [1.13; 1.16]), in contrast with low/very low SVI. Being a woman (voice: OR = 1.36 [1.35; 1.38]; psychological: 1.22 [1.21; 1.24]) and working in schools with various precarious conditions (17 variables) increased the odds of being absent due to voice and psychological symptoms. The results confirm the need for investments to improve working conditions in schools.

Changes in Screen Time in Brazil: A Time-Series Analysis 2016-2021.

PURPOSE: To analyze the temporal trend of leisure screen time among adults in Brazil between 2016 and 2021. DESIGN: Time-series analysis of six cross-sectional surveys. SETTING: Data from the Surveillance System for Risk and Protective Factors for Chronic Diseases by Telephone Survey (Vigitel) (2016/21). SUBJECTS: A probabilistic sample of 265 252 adults (≥18 years). MEASURES: Time watching television (TV), or using cell phone, computer, or tablet (CCT) during leisure time, and indicators of prolonged exposure for the total population and sociodemographic groups. ANALYSIS: Prais-Winsten regression models were used to identify trends in the studied period. RESULTS: Mean time watching TV remained stable (2.3 h to 2.2 h/day) as the frequency of adults watching TV ≥ 3 hours/day (25.7% to 25.1%) for 2016/21. There was an increase in mean time spent on CCT (1.7 h to 2.0 h/day; .08 h/day/year; P < .001) and in the frequency of adults spending ≥ 3 hours/day on CCT (19.9% to 25.5%; 1.33 pp/year; P < .001) for 2016/21. The increase in screen time was relevant in all sociodemographic groups. CONCLUSION: Leisure screen time has increased in Brazil, with greater intensity over time.

When asked about the main changes in the purchase and preparation of meals, 46.3% of the respondents reported consuming more food prepared at home during the pandemic. Regarding changes in eating habits, 48.6% of the respondents reported a change in their eating habits during the pandemic. The main reasons for such changes were greater concern with health (39.1%) and self-reported decreased family income (30.2%). CONCLUSIONS The covid-19 pandemic had a negative impact on the diet of the population, and increased consumption of ultra-processed foods was reported for that period.

No terceiro ciclo, também foram incluídas questões sobre mudanças nos hábitos alimentares durante a pandemia. Estimou-se a prevalência de consumo dos conjuntos de alimentos em cada ciclo da pesquisa e foram utilizados testes estatísticos para comparações de proporções entre os três ciclos. RESULTADOS Observou-se, entre 2019 e 2020, aumento significativo no consumo de cereais, leite, salgadinhos de pacote ou biscoitos salgados e molhos industrializados, em contraponto à diminuição do consumo de ovos. Entre 2019 e 2021 e entre 2020 e 2021, por outro lado, houve diminuição significativa no consumo de cereais, hortaliças, frutas e sucos de fruta industrializados e aumento no consumo de refrigerante, biscoito doce, recheado ou bolinho de pacote, embutidos, molhos industrializados e refeições prontas. Quando questionados sobre as principais mudanças na compra e preparo das refeições, 46,3% dos entrevistados relataram consumir mais alimentos preparados em casa durante a pandemia. Em relação a mudanças nos hábitos alimentares, 48,6% dos entrevistados relataram alteração na alimentação durante a pandemia. Os principais motivos para tais mudanças foram maior preocupação com a saúde (39,1%) e autorrelato de diminuição da renda familiar (30,2%). CONCLUSÕES A pandemia de covid-19 teve impacto negativo na alimentação da população, e foi reportado aumento no consumo de alimentos ultraprocessados durante esse período.

Leisure time physical activity among older adults in Brazil: a time series analysis of a population-based survey (2009-2020) / Atividade física no lazer entre idosos no Brasil: análise de séries temporais de um inquérito de base populacional (2009-2020) / Actividad física por ocio entre adultos mayores en Brasil: análisis de series temporales de una encuesta basada en la población (2009-2020)

The practice of leisure time physical activity brings several health benefits, such as the prevention of noncommunicable diseases. Investigating the temporal trend of physical activity practice in older adults by sociodemographic characteristics and geographical regions could be important to plan public health policies and effective interventions. This is a time series study that analyzes the temporal trend of leisure time physical activity among Brazilian older adults with data from 2009 to 2020. For this, we used a sample of 186,097 older adults (≥ 60 years old) obtained from the Risk and Protective Factors Surveillance System for Chronic Noncomunicable Diseases Through Telephone Interview (Vigitel) (2009-2020). Information on leisure time physical activity and sociodemographic and health characteristics were collected. Prais-Winsten regression was used to identify significant trends in the annual variation of the leisure time physical activity indicators. Practice of ≥ 150 minutes/week of moderate intensity leisure time physical activity varied from 23.3% to 27.5% (0.41p.p./year) (2009-2020), with a higher increase during 2015-2020 (0.59p.p./year). The increase in the most recent period occurred among men, aged from 60 to 69 years, with lower educational level, residing in the Northeast Region, and without self-reported chronic diseases. These results may contribute to the evaluation of Brazilian health policies targeting the leisure time physical activity practice in older adults.

A prática de atividade física no lazer traz diversos benefícios à saúde, como a prevenção de doenças não transmissíveis. Investigar a tendência temporal da prática de atividade física em idosos de acordo com características sociodemográficas e regiões geográficas pode ser importante para formular políticas públicas de saúde e intervenções efetivas. Este é um estudo de série temporal para analisar a tendência temporal de idosos brasileiros à prática de atividade física no lazer entre 2009 e 2020. Uma amostra de 186.097 idosos (≥ 60 anos) foi obtida do Sistema de Vigilância de Fatores de Risco e Proteção para Doenças Crônicas por Inquérito Telefônico (Vigitel) (2009-2020). Foram coletadas informações sobre prática de atividade física no lazer e características sociodemográficas e de saúde. A regressão de Prais-Winsten foi utilizada para identificar tendências significativas na variação anual dos indicadores de prática de atividade física no lazer. A prática de atividades físicas moderadas por ≥ 150 minutos/semana variou de 23,3% a 27,5% (0,41p.p./ano) (2009-2020) com maior aumento em 2015-2020 (0,59p.p./ano). O aumento mais recente ocorreu entre homens, indivíduos entre 60 e 69 anos de idade, aqueles com menor escolaridade, residentes na Região Nordeste e sem doença crônica autorreferida. Esses resultados podem contribuir para a avaliação das políticas de saúde brasileiras voltadas à prática de atividade física no lazer em idosos.

Time trends and COVID-19 post-pandemic changes in physical activity and sedentary behavior prevalence among Brazilian adults between 2006 and 2021 / Tendências temporais e mudanças pós-pandemia de COVID-19 na prevalência de atividade física e comportamento sedentário em adultos brasileiros entre 2006 e 2021

ABSTRACT Objective: To analyze time trends and prevalence of physical activity and sedentary behavior among adults of Brazilian capitals between 2006 and 2021, including the pandemic period. Methods: This is a time-series of cross-sectional surveys based on the National Surveillance System for Risk and Protective Factors for Chronic Diseases by Telephone Survey. Trends of sufficient leisure-time physical activity, sufficient physical activity while commuting, insufficient practice of physical activity, and total screen time were estimated by using Prais-Winsten regression. Annual prevalences and time trends were estimated for each indicator by sex, age group and education. Results: For total population, significant time trends were found for leisure-time physical activity (β=0.614) and total screen time (β=1.319). As for prevalence, leisure-time physical activity increased from 29% in 2009 to 39% in 2019, followed by a reduction of 2.3% between 2020 and 2021. Total screen time prevalence increased considerably between 2019 and 2020 (4.7%). Though physical inactivity tended to reduce along the series, its prevalence increased by 3.4% between 2019 and 2021, as well as physical activity while commuting decreased by 3,7% in the same time period. Conclusion: Whereas leisure-time physical activity increased over the years, it is uncertain whether this trend will be the same in the years following COVID-19. Not only did people alter their leisure-time habits, but also there was an increasing dominance of screen time due to the change in work and social patterns. More strategies need to be addressed to tackle physical inactivity and sedentary behavior, and to review the post-pandemic national targets.

RESUMO Objetivo: Analisar as tendências temporais e a prevalência dos indicadores de atividade física e comportamento sedentário em adultos das capitais brasileiras entre 2006 e 2021, incluindo o período de pandemia. Métodos: Trata-se de estudo de série temporal de inquéritos transversais baseado no Sistema de Vigilância Telefônica de Doenças Crônicas. As tendências de atividade física suficiente no lazer, atividade física suficiente no deslocamento, prática insuficiente de atividade física e tempo total de tela foram estimadas por meio da regressão de Prais-Winsten. As tendências temporais e as prevalências anuais foram calculadas por sexo, faixa etária e escolaridade. Resultados: Na população total, foram encontradas tendências temporais significativas para atividade física suficiente no lazer (β=0,614) e tempo total de tela (β=1,319). Quanto à prevalência, a atividade física suficiente no lazer aumentou de 29% em 2009 para 39% em 2019, seguida de redução de 2,3% entre 2020 e 2021. A prevalência do tempo total de tela aumentou consideravelmente entre 2019 e 2020 (4,7%). Embora a inatividade física tendesse a diminuir ao longo da série, sua prevalência aumentou 3,4% entre 2019 e 2021, assim como a atividade física no deslocamento diminuiu 3,7% no mesmo período. Conclusão: Enquanto a atividade física suficiente no lazer aumentou ao longo dos anos, é incerto se essa tendência se manterá nos anos seguintes à COVID-19. Não apenas as pessoas alteraram seus hábitos de lazer, mas também há um domínio crescente do tempo de tela em razão da mudança nos padrões sociais e de trabalho. Mais estratégias precisam ser abordadas para o enfrentamento da inatividade física, do comportamento sedentário e para a revisão das metas nacionais pós-pandemia.

Educational inequality in consumption of in natura or minimally processed foods and ultra-processed foods: The intersection between sex and race/skin color in Brazil.

Background: It remains uncertain how the intersection between educational, gender, and race/skin color inequalities influences food consumption in Brazil. In this study, we examined the educational inequality in the consumption of in natura/minimally processed and ultra-processed foods by Brazilians with an intersectional perspective between sex and race/color. Methods: We used cross-sectional data from the Telephone Surveillance System (VIGITEL 2019), comprising 52,443 participants ≥ 18 years. Daily food consumption was considered high when consumption of ≥5 foods for each food group was reported the day before the survey. Educational inequality in food consumption was assessed by the slope index of inequality (SII) and the relative index of inequality (RII) according to sex and race/color (White; Black/Brown). Positive SII and RII values > 1.0 indicate higher food consumption among more educated participants. Results: The consumptions of in natura/minimally processed and ultra-processed foods were more prevalent in those with the highest level of education (≥12 years) and intermediate education (9-11 years), respectively. However, highly educated White women had higher consumption of in natura/minimally processed foods than Black women with the same education level, and White men in low and intermediate school levels had higher consumption of these foods than Black men with the same education levels. We found higher absolute educational inequality for in natura/minimally processed foods among White women (SII 21.8, 95% CI 15.3, 28.4) and Black/Brown men (SII 19.3, 95% CI 12.5, 26.1). Black/Brown men (SII 7.3, 95% CI 0.5, 14.0) and Black/Brown women (SII 5.6, 95% CI 1.0, 10.2) had higher absolute educational inequality than White men (SII -3.3, 95% CI -10.9, 4.3; P = 0.04) in the consumption of ultra-processed foods. Conclusion: Educational inequalities influenced the consumption of in natura/minimally processed more than ultra-processed foods, and, for the latter, inequalities were greater among Black/Brown men and women than among White men.

Time trends and COVID-19 post pandemic changes in physical activity and sedentary behavior prevalence among Brazilian adults between 2006 and 2021 / Tendências temporais e mudanças pós-pandemia de COVID-19 na prevalência de atividade física e comportamento sedentário em adultos brasileiros entre 2006 e 2021

Objective: To analyze the time trends and prevalence of physical activity and sedentary behavior among Brazilian adults of state capitals between 2006 and 2021, including the pandemic period. Methods: This is a time series of cross-sectional surveys based on Telephone Surveillance for Chronic Diseases. Trends of sufficient leisure-time physical activity (LTPA), sufficient physical activity while commuting, insufficient practice of physical activity, and total screen time were estimated by using prais-winsten regression. Annual prevalence and time trends were estimated for each indicator by sex, age group and education. Results: For total population, significant time trends were found for LTPA (ß=0.614) and total screen time (ß=1.319). As for prevalence, LTPA increased from 29% in 2009 to 39% in 2019, followed by a reduction of 2.3% between 2020 and 2021. Total screen time prevalence increased considerably between 2019 and 2020 (4.7%). Though physical inactivity tended to reduce along the series, its prevalence increased by 3.4% between 2019 and 2021, as well as physical activity while commuting decreased by 3,7% in the same time period. Conclusion: Whereas LTPA increased along the years, it is uncertain whether this trend will be the same in the years following COVID-19. Not only people have altered their leisure-time habits, but also there is an increasing dominance of screen time due to changing working and social patterns. More strategies need to be addressed to tackle physical inactivity, sedentary behavior and review the national targets after the pandemic.
