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.

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.

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.

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.

Global case study of digital marketing on social media by a top soda brand.

The Big Soda segment is central in modern food systems, and they invest heavily in digital marketing, but little is known about it. We aimed to analyze the digital marketing on Facebook of the soda brand with a major worldwide reach. Countries were described in terms of soda brand presence and popularity on Facebook according to countries' socio-demographic index (SDI) and the market share of soda brand (%MS). From 149 countries, 57.0% had soda brand's Facebook page among the top five in the number of followers within the beverage segment. Among them, digital marketing was described by the number of the page followers, the number of posts, and the number of interactions (likes, comments and shares) that each post received by Facebook users. Also, we analyzed the characteristics, and the use of marketing strategies on posts in a random sample of 10% (n = 1217) of all posts. We found that soda brand's popularity on Facebook was higher among countries with higher SDI and higher %MS. Also, the number of users that engaged with soda brand's posts was higher among countries with lower SDI and higher brand's %MS. The brand's posts focus on young adults, display of brand's products and glorification of its attributes. Other identified features include sport-related thematic and appeals to socialization and healthy eating. In addition, posts' characteristics differed with countries' characteristics. Soda brand digital marketing varies according to countries' characterization and maintains the brand position on the global marketing of beverages.

The concentration of power of transnationals food and beverage corporations across the entire food system chain has contributed to unfavorable outcomes in the health and diets of the population. The reasons may be due to the low-nutritional value of the foods and beverages produced by these transnationals and the wide promotion of these products through marketing strategies. These two points are important stages of modern food systems. The marketing practices of these companies influence the food choices of individuals. They are attracted by the high level of persuasion employed through different strategies, especially in the digital environment. Strategies in the digital environment are widely available and accessed by individuals in every country in the world. For this reason, we focus on understanding the digital marketing of an important soda brand with a major worldwide reach to understand its particulars. We show that this top big soda brand uses digital marketing to promote its products globally and presenting particularities aligned with the socio-demographic conditions of the countries and regarding its market share. These results show that monitoring the behavior, especially on digital media, of large food and beverage companies is essential to advance policies that regulate market practices to protect individuals from their externalities in the field of global public health.

Behavioral Patterns with the Coexistence of Risk and Protective Factors for Cancer in Brazil.

About one third of the most common cancers could be prevented by the reduction of modifiable behavioral risk factors. We aimed to identify behavioral patterns of risk and protective factors for cancer in Brazil, between 2014 and 2015. Data from Vigitel Survey (n = 95,027 adults aged ≥ 18 years) from all Brazilian capitals and Federal District were used. Thirteen risk (RBF) and protective behavioral factors (PBF) for cancer were investigated. RBF included the consumption of red meat, meat with high-fat content, soft drinks, sweets and abusive alcohol, replacement of lunch/dinner for snacks, television viewing, obesity, and smoking. PBF included the consumption of beans, fruits and vegetables, and physical activity practice. Patterns were identified by principal component analysis and linear regressions models assessed its association with sociodemographic characteristics. Four behavioral patterns for cancer were identified. The 'healthy behavior pattern' and the 'unhealthy food consumption pattern' were positively associated to females and schooling. The 'unhealthy behavior pattern' and the 'mixed behavior pattern' were both negatively associated to females, age and schooling. Our data revealed different vulnerable population groups for cancer. Actions for reduction of modifiable behavioral risk factors aiming at cancer prevention should consider distinct approaches by sex, age, and schooling.

Trends in Prevalence of Cigarette Smoking in Brazil: 2006-2019.

Objectives. To analyze trends in cigarette smoking among Brazilian adults from 2006 to 2019.Methods. We performed a time-series analysis based on data from the Surveillance of Risk and Protective Factors for Chronic Diseases Telephone Survey (n = 730 309). We calculated the annual prevalence of current cigarette smokers, heavy smokers, and passive smokers in the workplace and investigated linear trends using Prais-Winsten regression, for the entire period and for the past 5 years. We performed the analyses for the total population and according to the sociodemographic characteristics.Results. The prevalence of cigarette smoking, heavy smoking, and passive smoking in the workplace declined, respectively, an average of 3.99% per year, 5.65% per year, and 6.55% per year from 2006 to 2019. We observed this reduction regardless of gender, age, educational level, and geographic region. The magnitude of reduction in the prevalence of current cigarette smoking decreased in the past 5 years, while the magnitude of the change in heavy smoking increased.Conclusions. The prevalence of cigarette smoking decreased in the time period studied. The smaller magnitude of reduction for current cigarette smoking in the most recent years might indicate a fatigue with the current policy scenario.

Advertising patterns of a fast-food chain on social media in Brazil.

OBJECTIVE: To investigate the advertising patterns on the posts of a fast-food chain in Brazil on three social media platforms in 2019. DESIGN: An exploratory cross-sectional study. SETTING: Advertising strategies on the posts of a major fast-food chain on their official Facebook, Instagram and YouTube accounts. The strategies were investigated according to the INFORMAS protocol for food promotion monitoring. Principal component analysis (PCA) was employed to identify advertising patterns in each platform. PARTICIPANTS: 305 advertisements. RESULTS: Four advertising patterns were identified in the PCA of Facebook and Instagram. In both platforms, the components for kids and product exaltation were similar. On Facebook, a pattern corresponding to economic appeal was identified as price and discount, while on Instagram, this pattern also included a practical approach. On Facebook, the fourth component was named celebrity, while on Instagram it was celebrity/innovation since on this second social media the component also included the 'new brand development' variable. On YouTube, three advertising patterns were identified in PCA. Similar to the other platforms, the first and the second patterns were called for kids and price and discount, and the third component referred to both celebrity and commemorative dates. CONCLUSIONS: The advertising patterns of the fast-food chain on three social media platforms were commonly directed to children and addressed price, discounts and the celebrities' universe. The findings of this study corroborate other data in the literature regarding unhealthy food advertising on social media. This study discusses the urgency of regulating food advertising content on this medium.

Association between the price of ultra-processed foods and obesity in Brazil.

BACKGROUND AND AIMS: To estimate the relationship between the price of ultra-processed foods and prevalence of obesity in Brazil and examine whether the relationship differed according to socioeconomic status. METHODS AND RESULTS: Data from the national Household Budget Survey from 2008/09 (n = 55 570 households, divided in 550 strata) were used. Weight and height of all individuals were used. Weight was measured by using portable electronic scales (maximum capacity of 150 kg). Height (or length) was measured using portable stadiometers (maximum capacity: 200 cm long) or infant anthropometers (maximum capacity: 105 cm long). Multivariate regression models (log-log) were used to estimate price elasticity. An inverse association was found between the price of ultra-processed foods (per kg) and the prevalence of overweight (Body mass index (BMI) ≥25 kg/m2) and obesity (BMI ≥30 kg/m2) in Brazil. The price elasticity for ultra-processed foods was -0.33 (95% CI: -0.46; -0.20) for overweight and -0.59 (95% CI: -0.83; -0.36) for obesity. This indicated that a 1.00% increase in the price of ultra-processed foods would lead to a decrease in the prevalence of overweight and obesity of 0.33% and 0.59%, respectively. For the lower income group, the price elasticity for price of ultra-processed foods was -0.34 (95% CI: -0.50; -0.18) for overweight and -0.63 (95% CI: -0.91; -0.36) for obesity. CONCLUSION: The price of ultra-processed foods was inversely associated with the prevalence of overweight and obesity in Brazil, mainly in the lowest socioeconomic status population. Therefore, the taxation of ultra-processed foods emerges as a prominent tool in the control of obesity.

Malnutrition in all its forms and social inequalities in Brazil.

OBJECTIVE: To describe malnutrition (undernutrition and excess weight) by income, education and race/ethnicity in the Brazilian population. DESIGN: Cross-sectional study. SETTING: Brazil. PARTICIPANTS: Children aged <5 years (n 14 580), adolescents aged 11-19 years (n 31 892) and adults aged 20-49 years (n 84 660). RESULTS: Among children, prevalence of excess weight, wasting and stunting was 16·9, 2·8 and 6·0 %, respectively. Differences related to income, education and race/ethnicity were verified, except for prevalence of wasting by education level. Girls and boys presented 18·4 and 20·5 % of excess weight, 2·8 and 3·7 % of underweight and 5·5 and 7·3 % of stunting, respectively. Prevalence of excess weight was lower among poorer, lower-educated (only for boys) and white adolescents, while stunting was lower among higher-income, higher-educated and white adolescents. Over three-quarters of women and almost half of men presented excess weight. Among adults, 3·9 % of women and 1·7 % of men were underweight, and 5·7 % of women and 0·2 % of men presented short stature. Prevalence of excess weight for women was higher among lower education and black, while for men it was higher among higher income and education and white. Short stature was more prevalent among black and mixed-race, low-educated and low-income women. Underweight prevalence was higher among low-educated, black and mixed-race women. CONCLUSIONS: In Brazil, the prevalence of excess weight was at least threefold higher than that of undernutrition for children and adolescents and at least sevenfold higher for adults. Social inequalities were observed in the distribution of malnutrition across the lifespan and by gender.

What to expect from the price of healthy and unhealthy foods over time? The case from Brazil.

OBJECTIVE: To measure change in price of food groups over time (1995-2030) in Brazil, considering the Brazilian Dietary Guidelines' recommendations. DESIGN: Data from the Household Budget Survey (2008-2009 HBS) and the National System of Consumer Price Indexes (NSCPI) were used to create a data set containing monthly prices for the foods and beverages most consumed in the country (n 102), from January 1995 to December 2017. Data on price of foods and beverages from 2008-2009 HBS (referring to January 2009) were used to calculate real price over time using the monthly variation in prices from NSCPI. All prices were deflated to December 2017. Foods and beverages were classified following the Brazilian Dietary Guidelines' recommendations. The monthly price for each food group and subgroup was used to analyse changes in prices from 1995 to 2017 and to forecast prices up to 2030 using fractional polynomial models. SETTING: Brazil. PARTICIPANTS: National estimates of foods and beverages purchased for Brazil. RESULTS: In 1995, ultra-processed foods were the most expensive group (R$ 6·51/kg), followed by processed foods (R$ 6·44/kg), then unprocessed or minimally processed foods and culinary ingredients (R$ 3·45/kg). Since the early 2000s, the price of ultra-processed foods underwent successive reductions, becoming cheaper than processed foods and reducing the distance between it and the price of the other group. Forecasts indicate that unhealthy foods will become cheaper than healthy foods in 2026. CONCLUSIONS: Food prices in Brazil have changed unfavourably considering the Brazilian Dietary Guidelines' recommendations. This may imply a decrease in the quality of the population's diet.

Ultra-processed food and beverage advertising on Brazilian television by International Network for Food and Obesity/Non-Communicable Diseases Research, Monitoring and Action Support benchmark.

OBJECTIVE: To analyse the extent and nature of food and beverage advertising on the three major Brazilian free-to-air television (TV) channels. DESIGN: Cross-sectional study. A protocol developed for the International Network for Food and Obesity/Non-Communicable Diseases Research, Monitoring and Action Support was applied for data collection. A total of 432 h of TV programming was recorded from 06.00 to 24.00 hours, for eight non-consecutive and randomly selected days, in April 2018. All TV advertisements (ads) were analysed, and food-related ads were classified according to the NOVA classification system. Descriptive analyses were used to describe the number and type of ads, food categories and the distribution of ads throughout the day and time of the day. SETTING: The three most popular free-to-air channels on Brazilian TV. PARTICIPANTS: The study did not involve human subjects. RESULTS: In total, 14·2 % (n 1156 out of 7991) of ads were food related (858 were specific food items). Approximately 91 % of food items ads included ultra-processed food (UPF) products. The top three most promoted products were soft drinks, alcoholic beverages and fast-food meals. Alcoholic beverage ads were more frequently broadcast in the evening. CONCLUSION: The high risk of exposure of the Brazilian population to UPF ads should be considered a public health concern given the impact of unhealthy food advertising on people's food choices and health.

Nutritional quality of foods and non-alcoholic beverages advertised on Brazilian free-to-air television: a cross-sectional study.

BACKGROUND: Evidence shows that foods marketed on television are often low-nutrient-dense foods associated with poor nutritional diet quality, obesity and non-communicable diseases. However, little research has been undertaken in Brazil around this issue. This study assessed the nutritional profile of foods and non-alcoholic beverages advertised on Brazilian television by applying the Pan American Health Organization (PAHO) and the World Health Organization (WHO/Europe) nutrient profiling models. METHODS: Cross-sectional study based on the International Network for Food and Obesity/non-communicable diseases Research, Monitoring and Action Support (INFORMAS) protocol. A total of 432 h on the three major Brazilian free-to-air TV channels was recorded from April 1st to 30th 2018. Recordings were done for eight non-consecutive and randomly selected days from 6 am to 12 am (midnight). All food-related ads were coded using a systematic approach and classified according to the PAHO and the WHO/Europe nutrient profile models as "eligible"/"not eligible" for marketing restrictions. Absolute and relative frequencies were used to describe absolute numbers and proportions of food and beverage advertisements. The nutritional profile of foods was compared by day, time of the day and types of TV program. For each advertisement, the parent company of promoted food products, supermarkets and restaurants was identified. RESULTS: A total of 1610 food and beverage ads were broadcast, representing 18.1% of the total ads shown on selected channels. Over 80.0% of all foods and beverages advertised on Brazilian TV channels did not meet the PAHO and the WHO/Europe nutritional quality standards and were considered eligible for marketing restrictions. The proportion of unhealthy food ads was significantly higher on weekends, in the afternoon, and during soap operas programming. Altogether, 10 transnational and local food and beverage companies, two large international fast food chains and two of Brazil's largest supermarket retailers accounted for almost 90% of all unhealthy food ads shown. CONCLUSIONS: The findings of the present study indicate a high exposure of the Brazilian population to unhealthy food marketing and an inefficient enforcement of existing regulations. Further research to monitor population exposure to unhealthy food marketing and understand the policy inertia that is preventing policy progress, is highly recommended.

Is neighbourhood social deprivation in a Brazilian city associated with the availability, variety, quality and price of food in supermarkets?

OBJECTIVE: To verify differences in the availability, variety, quality and price of unprocessed and ultra-processed foods in supermarkets and similar establishments in neighbourhoods with different social deprivation levels at Juiz de Fora, Minas Gerais, Brazil. DESIGN: Cross-sectional study. SETTING: The Obesogenic Environment Study in São Paulo's Food Store Observation Tool (ESAO-S) was applied in thirty-three supermarket chains, wholesale and retail supermarkets. RESULTS: Fruits, vegetables and ultra-processed foods were available in almost all establishments, without differences according to Health Vulnerability Index (HVI; which varies from 0 to 1 point and the higher the worse; P > 0·05). Most establishments were concentrated in low vulnerability areas and offered healthy foods with greater variety and quality, despite higher prices. The Healthy Food Store Index (HFSI; which varies from 0 to 16 points and the higher the best) was calculated from the ESAO-S and the mean score was 8·91 (sd 1·51). The presence and variety of unprocessed foods count as positive points, as do the absence of ultra-processed products. When HFSI was stratified by HVI, low HVI neighbourhoods presented higher HFSI scores, compared with medium, high and very high HVI neighbourhoods (P = 0·001). CONCLUSIONS: Supermarkets and similar establishments are less dense in areas of greater social deprivation and have lower prices of healthy foods, but the variety and quality of those foods are worse, compared with areas of low vulnerability. We found worse HFSI for supermarkets located in areas with greater vulnerability. Those findings can guide specific public policies improving the urban food environment.

Trends in sweetened beverages consumption among adults in the Brazilian capitals, 2007-2016.

OBJECTIVE: To analyse trends in sweetened beverages consumption among adults in Brazil between 2007 and 2016. DESIGN: A time-series analysis, with data from the Surveillance System of Risk and Protection Factors for Chronic Diseases by Telephone Survey (VIGITEL). The prevalence of regular consumption (≥5 d/week), the average daily consumption (millilitres) and the prevalence of non-consumption of these beverages were analysed. The temporal variations of the indicators were calculated by linear regression. The analyses were performed for the complete set of the evaluated population and stratified by sociodemographic characteristics. SETTING: Brazilian capitals and Federal District. SUBJECTS: Brazilian adults aged ≥18 years (n 519 641). RESULTS: There was a reduction in both regular and average daily consumption of sugar- and artificially sweetened beverages (-1·28 percentage points (pp)/year, P=0·001 and -9·63 ml/year, P=0·001, respectively). The same result regarding regular consumption was found when only sugar-sweetened beverages were analysed (-1·11 pp/year, P=0·011). Similar trends were identified in the stratified analyses, with a greater magnitude of reduction among males, young adults, those with higher schooling and residents of more developed regions. Coincidentally, there was an increase in the prevalence of adults who did not consume sweetened beverages (1·54 pp/year, P=0·005). CONCLUSIONS: The consumption of sweetened beverages decreased during the period. However, a significant portion of the population still referred a daily consumption of these beverages.

Is food store type associated with the consumption of ultra-processed food and drink products in Brazil?

OBJECTIVE: To analyse the association between food store type and the consumption of ultra-processed products in Brazil. DESIGN: Data from the 2008-2009 Household Budget Survey involving a probabilistic sample of 55 970 Brazilian households. Food stores were grouped into nine categories. Foods and drinks were grouped according to characteristics of food processing. The contribution of each food store type to the total energy acquired from each food processing group, and according to quintiles of consumption of ultra-processed products, was estimated. Exploratory factor analysis was conducted to identify a pattern of food store usage. Linear regression models were performed to estimate the relationship between the purchase pattern and the consumption of ultra-processed products. RESULTS: In line with their larger market share, supermarkets accounted for 59 % of total energy and participated most in acquisition for three food groups, with emphasis on ultra-processed products (60·4 % of energy). The participation of supermarkets in total purchase tended to increase in populations with higher consumption of ultra-processed products, while the participation of small markets and small producers tended to decrease. The purchase pattern characterized by use of traditional retail (street fairs and vendors, small markets, small farmers, butcheries) was associated with a smaller consumption of ultra-processed products. CONCLUSIONS: Food policies and interventions aiming to reduce the consumption of ultra-processed products should consider the influence of supermarkets on the consumption of these products. A purchase pattern based on traditional retail constitutes an important tool for promoting healthy eating in Brazil.

Needed Improvements in Diabetes Prevention and Management in Brazil.

INTRODUCTION: Diabetes mellitus is one of the most common chronic diseases worldwide and its prevalence continues to increase. Adherence to good health behaviors provides better control of the disease. This study analyzed trends in the prevalence of diabetes among Brazilian adults between 2006 and 2016 and compared the frequency of key health behaviors between people with and without diabetes. METHODS: We analyzed data from 572,437 Brazilian adults interviewed between 2006 and 2016 by using the Surveillance System of Risk and Protection Factors for Chronic Diseases by Telephone Survey (Vigitel). We used regression models to investigate significant trends in the prevalence of diabetes and differences in adherence to health behaviors between people with and without diabetes. RESULTS: The prevalence of diabetes increased significantly from 5.5% to 8.9% (P <.001), being higher among women, older adults, and those with less than a high school education. The greatest increase was observed among these groups with higher prevalence. People with diabetes had a lower frequency of risk behaviors and a higher frequency of protective behaviors when compared to people without diabetes. The greatest differences were observed in the consumption of soft drinks and sugar-sweetened beverages (9.5% vs 25.0%) and alcoholic beverages (9.0% vs 17.9%), and the smallest differences were related to regular consumption of fruits and vegetables (40.7% vs 34.0%) and meats with excess fat (24.3% vs 32.2%). People with diabetes reported less leisure-time physical activity (PRa, 0.92 [P < .001]) and less transport-related physical activity (PRa, 0.84 [P <.001]) than those without diabetes. CONCLUSION: Diabetes prevalence increased between 2006 and 2016. People with diabetes had better dietary habits than those without diabetes, but still had risk behaviors such as insufficient physical activity.

Coexistence of risk behaviors for being overweight among Brazilian adolescents.

This study aimed to evaluate the magnitude of and the factors associated with the coexistence of risk behaviors for being overweight among Brazilian adolescents. This is a cross-sectional study with a representative sample of adolescents (mostly aged 13-15years) enrolled from public and private schools of Brazil in 2012. The co-occurring sedentary behavior and inadequate food consumption (regular intake of sugary and fried foods, and irregular consumption of fruits and vegetables-FV) was estimated using a Venn diagram. Sociodemographic, familial, and behavioral factors associated with the number of risk behaviors for being overweight were identified using an ordinal logistic regression analysis. Sedentary behavior was observed in 62.0% of adolescents. Regular intake of sugary or fried food was observed in 55.3% and 23.5% of adolescents, respectively, with 51.9% having an inadequate intake of FV. At least one risk behavior was reported in >90.0% of adolescents; 6.1% reported all 4. Being female, having a higher maternal education level, attending private school, not having breakfast or meals with parents regularly, eat watching television, and not practicing weekly leisure time physical activity were associated with an increased chance of having multiple risk behaviors. This study observed a high prevalence of coexisting of risk behaviors, which was associated with sociodemographic, familial, and behavioral factors. These findings may contribute to a clearer understanding of the associations between different behaviors among adolescents, and may be used to improve public health surveillance and to develop strategies that address multiple behaviors, in order to prevent overweight among adolescents.

Price and convenience: The influence of supermarkets on consumption of ultra-processed foods and beverages in Brazil.

OBJECTIVE: To evaluate the influence of convenience and price of ultra-processed foods and beverages on purchases at supermarkets. METHODS: The study used data on food and beverage acquisition for household consumption from the Brazilian Household Budget Survey, performed in a random sample of 55,970 households between 2008 and 2009. Foods and beverages were categorized into four groups, according to characteristics of food processing. Retail stores were grouped into supermarkets and other food stores. Proportion of calories from foods and beverages purchased at supermarkets and other food stores, and respective mean prices (R$/1000 kcal), were calculated according to households' geographical and socioeconomic characteristics. Effect of convenience in household purchases at retail stores was expressed by the acquisition of several food items at the same store. The influence of convenience and prices of ultra-processed products on purchases at supermarkets was analyzed using log-log regression model with estimation of elasticity coefficients. RESULTS: The mean prices of foods and beverages purchased at supermarkets were 37% lower in comparison to other food stores. The share of ultra-processed foods and beverages in purchases made at supermarkets was 25% higher than at other food stores. An increase of 1% in prices of ultra-processed food items led to a 0.59% reduction in calorie acquisition at supermarkets (R2 = 0.75; p < 0.001). On the other hand, an increase of 1% in the number of food items purchased at supermarkets resulted in 1.83% increase in calorie acquisition of ultra-processed foods and beverages (p < 0.001). CONCLUSION: Convenience and lower relative prices of food items purchased at supermarkets, in comparison to other food stores, are relevant to explain higher share of purchases of ultra-processed foods and beverages at supermarkets.

Food environments in schools and in the immediate vicinity are associated with unhealthy food consumption among Brazilian adolescents.

BACKGROUND: Evidence of the influence of the school food environment on adolescent diet is still little explored in low- and middle-income countries. We aimed to evaluate the association between food environment in schools and the immediate vicinity and the regular consumption of unhealthy food among adolescents. METHODS: We used cross-sectional data collected by the Brazilian National Survey of School Health (PeNSE) from a representative sample of adolescents attending 9th grade public and private schools in Brazil, in 2012. We estimated students' regular consumption (>5days/week) of unhealthy food (soft drinks, bagged salty snacks, deep fried salty snacks and sweets) and school availability, in the cafeteria or an alternative outlet, of the same food plus some healthy options (fruit and natural fruit juice). We performed multilevel logistic regression models. RESULTS: Having a cafeteria inside school selling soft drinks (private schools OR=1.23; 95% CI=1.14-1.33; public schools OR=1.13; 95% CI=1.06-1.20) and deep fried salty snacks (private schools OR=1.41 95% CI=1.26-1.57; public schools OR=1.16 95% CI=1.08-1.24) was associated with a higher consumption of these unhealthy foods of among students. In private schools, cafeteria selling fruit and natural fruit juice was associated with lower student consumption of bagged salty snacks (OR=0.86; 95% CI 0.77-0.96) and soft drinks (OR=0.85; 95% CI=0.76-0.94). In addition, eating meals from the Brazilian School Food Program in public schools was associated with a lower consumption of unhealthy foods. CONCLUSIONS: Foods available in the school food environment are associated with the consumption of unhealthy food among adolescents in Brazil.
