- The share of ultra-processed foods determines the overall nutritional quality of diets in Brazil(2018) LOUZADA, Maria Laura da Costa; RICARDO, Camila Zancheta; STEELE, Euridice Martinez; LEVY, Renata Bertazzi; CANNON, Geoffrey; MONTEIRO, Carlos AugustoObjective To estimate the dietary share of ultra-processed foods and to determine its association with the overall nutritional quality of diets in Brazil. Design Cross-sectional. Setting Brazil. Subjects A representative sample of 32 898 Brazilians aged 10 years was studied. Food intake data were collected. We calculated the average dietary content of individual nutrients and compared them across quintiles of energy share of ultra-processed foods. Then we identified nutrient-based dietary patterns, and evaluated the association between quintiles of dietary share of ultra-processed foods and the patterns' scores. Results The mean per capita daily dietary energy intake was 7933 kJ (1896 kcal), with 581 % from unprocessed or minimally processed foods, 109 % from processed culinary ingredients, 106 % from processed foods and 204 % from ultra-processed foods. Consumption of ultra-processed foods was directly associated with high consumption of free sugars and total, saturated and trans fats, and with low consumption of protein, dietary fibre, and most of the assessed vitamins and minerals. Four nutrient-based dietary patterns were identified. Healthy pattern 1' carried more protein and micronutrients, and less free sugars. Healthy pattern 2' carried more vitamins. Healthy pattern 3' carried more dietary fibre and minerals and less free sugars. Unhealthy pattern' carried more total, saturated and trans fats, and less dietary fibre. The dietary share of ultra-processed foods was inversely associated with healthy pattern 1' (-016; 95 % CI -017, -015) and healthy pattern 3' (-018; 95 % CI -019, -017), and directly associated with unhealthy pattern' (017; 95 % CI 015, 018). Conclusions Dietary share of ultra-processed foods determines the overall nutritional quality of diets in Brazil.
- Eating meals with parents is associated with better quality of diet for Brazilian adolescents(2019) MARTINS, Bianca Garcia; RICARDO, Camila Zancheta; MACHADO, Priscila Pereira; RAUBER, Fernanda; AZEREDO, Catarina Machado; LEVY, Renata BertazziThe objective was to investigate how often Brazilian adolescents eat meals with their parents and verify the association between this habit and quality of the diet. Data were from the Brazilian National Survey of School Health (PeNSE 2015). The sample consisted of adolescents enrolled in the ninth grade in public and private schools, ranging in age from 11 to 19 years. The target exposure was eating meals with parents (0-4 and >= 5 days/ week) and the outcomes were frequent consumption (>= 5 days/week) of healthy and unhealthy dietary markers. Healthy diet scores (range 0-21) and unhealthy diet scores (range 0-35) were based on total days that the adolescent reported consuming each of the dietary markers. Poisson and linear regression models were used, adjusted by sociodemographic variables. Frequent sharing of meals with parents (>= 5 days/week) was seen in 74% (9.5%CI: 73.4-74.7) of the adolescents. Those reporting this habit showed higher likelihood of frequent consumption of beans (PR = 1.22; 9.5%CI: 1.19-1.26), fruits (PR = 1.34; 9.5%CI: 1.28- 1.39), and vegetables (PR = 1.39; 9.5%CI: 1.34-1.44), and lower likelihood of frequent consumption of sweets (PR = 0.91; 95%CI: 0.88-0.94), ultra-processed salty foods (PR = 0.91; 95%CI: 0.87-0.94), and fried salty snacks (PR = 0.85; 95%CI: 0.80-0.90). Eating meals with parents was positively associated with healthy diet scores and inversely associated with unhealthy diet scores . Eating meals with parents is a common habit in Brazilian adolescents and is associated with better quality of diet.
conferenceObject PATTERNS OF RISK AND PROTECTIVE BEHAVIORS RELATED TO NON-COMMUNICABLE DISEASES AMONG BRAZILIAN ADOLESCENTS(2017) RICARDO, Camila; AZEREDO, Catarina; LEVY, Renata- Out-of-Home Food Consumers in Brazil: What Do They Eat?(2018) ANDRADE, Giovanna Calixto; LOUZADA, Maria Laura da Costa; AZEREDO, Catarina Machado; RICARDO, Camila Zancheta; MARTINS, Ana Paula Bortolleto; LEVY, Renata BertazziConsidering the increased contribution of foods consumed outside home and their potential impact on diet, this study aims to identify eating out patterns and their association with nutritional dietary quality in Brazil. We used the Individual Food Intake Survey 2008-2009, conducted with 34,003 individuals aged 10 and up. We used factor analysis by principal component to identify out-of-home eating patterns and linear regression to explore the association between patterns scores and dietary quality. We identified three food patterns. The Traditional meal pattern carried more rice, beans, meat, roots and tubers, pasta, vegetables and eggs. The typical Brazilian breakfast/tea pattern carried more fresh bread, margarine, milk, cheese and butter. The Ultra-processed food pattern carried more ready-to-eat meals and soft drinks. The traditional meal pattern was positively associated with calories from proteins, fiber, iron, potassium and sodium densities, whereas typical Brazilian breakfast/tea and ultra-processed food patterns were positively associated with energy density, the percentage of calories from lipids or carbohydrates, trans fat and free sugar. Out-of-home eating may have a negative impact on nutritional dietary quality when based on ultra-processed food. However, it is possible to maintain a healthy out-of-home diet with adherence to traditional Brazilian cuisine.
conferenceObject FOOD-BASED DIETARY PATTERNS AND NUTRITIONAL QUALITY OF MEALS IN BRAZIL (2008-2009)(2017) MACHADO, Priscila Pereira; LOUZADA, Maria Laura da Costa; ANDRADE, Giovanna; RICARDO, Camila; LEVY, Renata- Co-occurrence and clustering of the four major non-communicable disease risk factors in Brazilian adolescents: Analysis of a national school-based survey(2019) RICARDO, Camila Zancheta; AZEREDO, Catarina Machado; REZENDE, Leandro Fornias Machado de; LEVY, Renata BertazziBackground The major non-communicable chronic diseases (NCD) are associated with a small group of modifiable lifestyle-related risk factors, including smoking, insufficient physical activity, unhealthy eating, and alcohol abuse. In this study, we evaluated the co-occurrence and clustering of the major NCD risk factors among Brazilian adolescents. Methods This cross-sectional study analyzed data of 101,607 adolescents from the Brazilian National Survey of School Health (PeNSE) 2015. The risk factors included were: regular consumption of ultra-processed foods, irregular consumption of fruits and vegetables, insufficient physical activity, smoking, and alcohol consumption. Clustering was defined through the ratio between observed and expected prevalences of combination of risk factors greater than 1. Expected prevalence of the co-occurrence of risk factors was calculated from the joint probability of the behaviors. Additionally, we examined the presence of at least four risk factors according to socioeconomic characteristics. Results Of the 32 combinations of risk factors, 13 corresponded to clustering. We observed a strong correlation between alcohol consumption and smoking, which were found together in 8 of the 13 clusters identified. The most frequent combinations of risk factors involved unhealthy eating and insufficient physical activity. Only 2.9% of the adolescents did not present any risk behaviors, while 38.0%, 32.9%, 9.4% and 1.8% accumulated two, three, four and five risk factors, respectively. The accumulation of risk factors was higher in girls, older adolescents, those who did not live with both parents, children of less-educated mothers, students attending public school, and residents of cities in more developed urban areas of the country. Conclusions The main risk factors for NCD are frequent and not randomly distributed among Brazilian adolescents. Our results provide information for policymakers to target specific groups and joint behavioral risk factors for health improvement in adolescents.
- Progress and setbacks in socioeconomic inequalities in adolescent health-related behaviours in Brazil: results from three cross-sectional surveys 2009-2015(2019) AZEREDO, Catarina Machado; REZENDE, Leandro F. M. de; MALLINSON, Poppy Alice Carson; RICARDO, Camila Zancheta; KINRA, Sanjay; LEVY, Renata B.; BARROS, Aluisio J. D.Objectives Despite some progress, Brazil is still one of the most unequal countries, and the extent of socioeconomic inequalities in adolescent health is unclear. We assessed trends in socioeconomic inequalities in adolescent's health-related behaviours in Brazil between 2009 and 2015. Design We used cross-sectional data from the Brazilian National Survey of School Health carried out in 2009, 2012 and 2015. Setting Brazilian state capitals. Participants Students attending ninth grade from public and private schools in Brazilian state capitals in 2009 (60 973 students), 2012 (61 145 students) and 2015 (51 192 students). Main outcome measure We assessed 12 health-related behaviours (irregular fruit, vegetables and bean consumption; regular soft drink consumption; irregular physical activity; alcohol, drug and tobacco use; unsafe sex; involvement in gun fights; bullying victimisation and domestic violence victimisation), under the broad domains of lifestyle risk behaviours, engagement in risky activities and exposure to violence. Socioeconomic status was assessed through an asset-based wealth index derived from principal component analysis. Absolute and relative inequalities in these health behaviours and inequalities trends were investigated. Results From 2009 to 2015, prevalence of certain harmful health-related behaviours increased, such as unsafe sex (21.5% to 33.9%), domestic violence (9.5% to 16.2%), bullying victimisation (14.2% to 21.7%) and irregular consumption of beans (37.5% to 43.7%). Other indicators decreased: alcohol use (27.1% to 23.2%), irregular physical activity (83.0% to 75.6%) and consumption of soft drinks (37.2% to 28.8%). Over the period, we found consistent evidence of decreasing health inequalities for lifestyle behaviours (fruit, bean and soft drink consumption) and alcohol use, set against increasing inequalities in violence (domestic violence, fights using guns and bullying victimisation). Conclusion Socioeconomic inequality increased in the violence domain and decreased for lifestyle behaviours among Brazilian adolescents. Widening gaps in violence domain urge immediately policy measures in Brazil.
