- Vaccination coverage rates and predictors of HPV vaccination among eligible and non-eligible female adolescents at the Brazilian HPV vaccination public program(2020) FAISAL-CURY, Alexandre; LEVY, Renata Bertazzi; TOURINHO, Maria Fernanda; GRANGEIRO, Alexandre; ELUF-NETO, JoseBackground Since March 2014, the quadrivalent HPV vaccine has been incorporated into the Brazilian Unified Health Care System and began to be offered, without direct costs, for girls from 9 to 13 years of age. Older female adolescents would have the option to be vaccinated at private health care system being responsible for the payment of HPV vaccine. The present study aimed to evaluate the coverage rates and predictors of HPV vaccination in Brazil among two groups of female adolescents: eligible and non-eligible for the HPV vaccination public program. Methods We used data from the 2015 Brazilian National Adolescent School-Based Health Survey, which involved a probabilistic sample of 5404 female adolescents students at public and private schools. Using a questionnaire, we gathered information on sociodemographic characteristics, sexual behavior, and respondent perception of parental supervision and have been vaccinated for HPV. Age-specific vaccination rates were analyzed in girls aged 9 to 13 at the time of public vaccination (eligible for public policy), as well among those 14 to 17 years old not eligible by the Ministry of Health for vaccination. We used Poisson regression models to investigate associated factors. Results HPV vaccine coverage was 83.5 and 21.8% among eligible and non-eligible populations, respectively. In both populations, the chance of being vaccinated decreased with older age. In the eligible population there is a greater chance of being vaccinated among ethnic group ""pardas"" but not with other indicators of socioeconomic status. In the non-eligible population, there was a clear association between higher vaccine coverage and greater maternal education and living with the mother. Conclusion Our findings highlight the importance of public policies to minimize inequities in access to cancer prevention measures in vulnerable adolescents. A public policy of HPV vaccination for older female adolescents would increase coverage with possible reduction of HPV-related diseases in this group of women.
- Food environments in schools and in the immediate vicinity are associated with unhealthy food consumption among Brazilian adolescents(2016) AZEREDO, Catarina Machado; REZENDE, Leandro Fornias Machado de; CANELLA, Daniela Silva; CLARO, Rafael Moreira; PERES, Maria Fernanda Tourinho; LUIZ, Olinda do Carmo; FRANCA-JUNIOR, Ivan; KINRA, Sanjay; HAWKESWORTH, Sophie; LEVY, Renata BertazziBackground. 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 (>5 days/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.
- Association Between Dietary Patterns and Bullying Among Adolescents in Sao Paulo-Brazil(2024) OKADA, Leticia Martins; MARQUES, Emanuele Souza; LEVY, Renata Bertazzi; PERES, Maria Fernanda Tourinho; AZEREDO, Catarina MachadoPrevious studies have assessed the association between food consumption and bullying perpetration, but most of them have not broadly assessed food consumption, neither the distinction between forms of bullying. The aim of the study was to evaluate the association between dietary patterns with bullying roles and its different types of bullying perpetration among adolescents. Data on a representative sample of ninth-grade students (N = 2,163; mean age = 14.8 years) taken from Sao Paulo Project for the social development of children and adolescents (SP-PROSO) were used. The independent variables were healthy and unhealthy dietary patterns obtained by exploratory factor analysis. The dependent variables were bullying role (victim-only, bully-only, bully-victim) and bullying perpetration (any type, social exclusion, psychological/verbal aggression, physical aggression, property destruction, sexual harassment). Multinomial and logistic regression models were performed for the total sample and stratified by sex (only for association with sexual harassment), adjusting for covariates. Adolescents who engaged in a healthy dietary pattern were less likely to be bullies (RR 0.67 [0.49, 0.92]), while adolescents with an unhealthy dietary pattern were more likely to be bully-victims (RR 1.29 [1.12, 1.48]). Unhealthy dietary pattern was associated with any type of bullying perpetration (OR 1.24 [1.12, 1.38]), mainly with sexual harassment and physical aggression. Boys who had an unhealthy dietary pattern were more likely to sexually harass another adolescent (OR 2.10 [1.20, 3.66]). In conclusion, adolescents who had a healthy dietary pattern were less likely to perpetrate bullying. Unhealthy dietary pattern was associated with bullying perpetration, especially with sexual harassment by boys.
- Patterns of health-related behaviours among adolescents: a cross-sectional study based on the National Survey of School Health Brazil 2012(2016) AZEREDO, Catarina Machado; LEVY, Renata Bertazzi; PERES, Maria Fernanda Tourinho; MENEZES, Paulo Rossi; ARAYA, RicardoObjectives: The aim of this study was to analyse the clustering of multiple health-related behaviours among adolescents and describe which socio-demographic characteristics are associated with these patterns. Design: Cross-sectional study. Setting: Brazilian schools assessed by the National Survey of School Health (PeNSE, 2012). Participants: 104 109 Brazilian ninth-grade students from public and private schools (response rate= 82.7%). Methods: Exploratory and confirmatory factor analyses were performed to identify behaviour clustering and linear regression models were used to identify socio-demographic characteristics associated with each one of these behaviour patterns. Results: We identified a good fit model with three behaviour patterns. The first was labelled 'problem-behaviour' and included aggressive behaviour, alcohol consumption, smoking, drug use and unsafe sex; the second was labelled 'health-compromising diet and sedentary behaviours' and included unhealthy food indicators and sedentary behaviour; and the third was labelled 'health-promoting diet and physical activity' and included healthy food indicators and physical activity. No differences in behaviour patterns were found between genders. The problem-behaviour pattern was associated with male gender, older age, more developed region (socially and economically) and public schools (compared with private). The 'health-compromising diet and sedentary behaviours' pattern was associated with female gender, older age, mothers with higher education level and more developed region. The 'health-promoting diet and physical activity' pattern was associated with male gender and mothers with higher education level. Conclusions: Three health-related behaviour patterns were found among Brazilian adolescents. Interventions to decrease those negative patterns should take into account how these behaviours cluster together and the individuals most at risk.

- The relationship between ultra-processed food consumption and internalising symptoms among adolescents from Sao Paulo city, Southeast Brazil(2022) FAISAL-CURY, Alexandre; LEITE, Maria Alvim; ESCUDER, Maria Mercedes Loureiro; LEVY, Renata Bertazzi; PERES, Maria Fernanda TourinhoObjective: To investigate the association between ultra-processed food (UPF) consumption and internalising symptoms (IS) among adolescents. Design: It is a cross-sectional study. Paper-pencil survey was completed in classroom with information on UPF consumption, IS and selected covariates. IS were assessed with the Internalizing Symptoms sub-scale from the Social Behaviour Questionnaire (IS-SBQ). UPF was evaluated with a FFQ extracted from the Brazilian National School Health Survey. Crude and adjusted association between UPF and IS was investigated with structural equation models. Setting: Sao Paulo, SP, Brazil. Participants: A total of 2680 students, M-age = 14 center dot 85; (95 % CI 14 center dot 81, 14 center dot 88). Results: UPF consumption was associated with higher scores in IS in the crude (beta = 0 center dot 14; P < 0 center dot 001) and adjusted (beta = 0 center dot 12; P < 0 center dot 001) models. The higher the consumption of UPF, the higher is the IS score. The following variables were associated with a lower risk of UPF consumption: male sex, public school and having more meals with parents. The change in the magnitude of the standardised score was almost negligible, but the model was significantly improved with the inclusion of covariates. Conclusions: Our results provide evidence about the positive association between UPF consumption and IS among adolescents. The association, despite its low magnitude, remained significant after adjusting for potential confounders. These results are relevant considering the increase in UPF consumption worldwide and in low- and middle-income countries. Also, our study emphasises the importance of a healthy diet with a reduction in UPF consumption among adolescents.
- Availability and consumption of ultra-processed foods in schools in the municipality of Sao Paulo, Brazil: results of the SP-Proso(2021) LEITE, Maria Alvim; AZEREDO, Catarina Machado; PERES, Maria Fernanda Tourinho; ESCUDER, Maria Mercedes Loureiro; LEVY, Renata BertazziUltra-processed foods are markers of unhealthy eating patterns, and their consumption is high among adolescents. Characteristics of the school eating environment associate with student eating practices. This study aims to investigate the association between the presence of school canteens and the availability of ultra-processed foods in school canteens with the consumption of these foods, inside the school, among adolescents of the 9th grade (14 years) of the public and private schools of the city of Sao Paulo, Brazil. We conducted a cross-sectional study with SP-Proso data, in a sample of 2,680 adolescents. We elaborated multilevel linear regression models to evaluate associations between the exposures: presence of school canteens and availability of ultra-processed foods with outcomes of consumption frequency of ultra-processed foods in the school. We found an association between the presence of school canteens and the higher frequency of consumption of sausages (0.46; 95%CI: 0.24; 0.68), package snacks (0.50 95%CI: 0.19; 0.80), goodies (0.82; 95%CI: (155; L09), and sugary drinks (a 34; 95%Cl: (106; 0.62), as well as a score of consumption frequency of ultra-processed foods (2.37: 95%CI: 1.25; 3.48). The availability of package snacks, goodies, and sugary drinks in school canteens increased the frequency of consumption of these foods. We observed a dose-response effect between the diversity of ultra-processed foods in canteens and the frequency of consumption of these foods. A school food environment with greater availability of ultra-processed products is associated with their higher consumption in school, indicating the need to regulate the sale of food within these institutions.
- BEING YOUNG-BLACK-MALE INCREASES THE ODDS OF SUFFERING POLICE NON-LETHAL VIOLENCE IN BRAZIL, ACCORDING TO THE NATIONAL HEALTH SURVEY 2013(2018) PERES, Maria Fernanda; LEVY, Renata Bertazzi; REZENDE, Leandro Fornias Machado de; LUIZ, Olinda do Carmo; GRANGEIRO, Alexandre
- Relationship between polyvictimization and overweight among adolescents from Sao Paulo city, Brazil(2023) MARQUES, Emanuele Souza; FAUS, Daniela Porto; LEVY, Renata Bertazzi; LEITE, Maria Alvim; EISNER, Manuel P.; PERES, Maria Fernanda TourinhoThis study is to identify victimization patterns and analyze the association between the experience of poly -victimization and overweight or obesity among adolescent girls and boys. The sample consisted of 2680 Brazilian ninth-graders enrolled in public and private schools, taken from the Sa similar to o Paulo Project for the social development of children and adolescents (SP-PROSO). Victimization was explored in two ways: (i) as per Finkelhor and (ii) by latent class analysis (LCA). The interest outcomes were overweight and obesity. Multinomial logistic regression models were used to study the relationship between victimization and overweight or obesity, controlling for confounders. LCA grouped boys and girls adolescents into three classes. These classes received the same labels, but the patterns differed between sexes. Class 1 was characterized by fewer types of victimization suffered and lower endorsement values in the analyzed items and was named bullying and indirect victimization (9: 42.7%, n = 546; male: 21.6%, n = 293). Class 2 included more victimization types than Class 1 and less than Class 3. This class was labeled family violence and peer victimization (9: 29.1%, n = 356; male: 47.9%, n = 652). Class 3 was named high polyvictimization (9: 28.2%, n = 345; male: 30.5%, n = 418). According to Finkelhor, polyvictimization was not associated with overweight or obesity in both sexes. Only the class of high polyvictimization was associated with being overweight (ORadj: 1.60, 95%CI: 1.01-2.54) in girls. In this study, polyvictimization was associated with being overweight only among adolescent girls. Longitudinal studies in different contexts and populations are needed to understand this relationship.
