Association between ultra-processed dietary pattern and bullying: the role of deviant behaviors.

Background: Ultra-processed foods have been associated with several negative outcomes, but it is not clear whether they are related to bullying perpetration. Moreover, no previous study has investigated the potential role of deviant behaviors as a mediator of this association. Our objective was to evaluate the association between ultra-processed dietary pattern and bullying, and the mediating effect of deviant behaviors in this association, among school adolescents. Methods: We used data from a representative sample of 9th grade Brazilian adolescents (N = 2,212) from the São Paulo Project for the social development of children and adolescents (SP-PROSO). Exploratory factor analysis was used to obtain the dietary patterns, through questions of frequency of consumption in the last week of several foods. The ultra-processed dietary pattern was considered as exposure. The outcomes were the types of bullying (any type, social exclusion, psychological/verbal aggression, physical aggression, property destruction, and sexual harassment). Deviant behaviors (mediator) were assessed through a score. Mediation analyses were carried out using logistic regression based on the KHB method. Results: After adjusting for covariates, the mediating effect of deviant behaviors was found in the association between ultra-processed dietary pattern and all the types of bullying perpetration, especially for psychological/verbal aggression (39.4%). A small mediating effect of deviant behaviors in the association of ultra-processed dietary pattern with physical aggression (17.7%) and property destruction (18.5%) was observed, but this effect explained only a small portion of the total effect of such association (significant direct effect). Conclusion: The ultra-processed dietary pattern was associated with bullying, and the association was mediated through deviant behaviors. Policies and actions for improving the adolescent's diet and managing the adoption of deviant and bullying behaviors by this public are required.

Association between health risk behaviors and food consumption in adolescents.

The study aims to evaluate the association between substance use and social isolation with food consumption in adolescents. A cross-sectional study was conducted with 2,040 adolescents from a medium-sized city in Brazil. The exposures assessed were the use of alcohol, tobacco, and other substances, and social isolation. The outcomes were the regular consumption (≥5 times/week) of beans, fruit/fruit salad, candies, and soft drinks, and an unhealthy eating score. The association between health risk behaviors and food consumption was assessed through logistic and linear regressions. Regular users of alcohol were more likely to have regular consumption of candies and soft drinks, and those who used tobacco regularly were less likely to have regular bean consumption and more likely to have regular candies consumption. The use of at least one substance was negatively associated with regular bean consumption and positively associated with regular consumption of sweets and soft drinks. Socially isolated adolescents were less likely to have regular bean consumption. Substance use was positively associated with the unhealthy eating score. In conclusion, substance use and social isolation were associated with less regular consumption of healthy food markers and greater regular consumption of unhealthy food markers.

Association between Community Violence, Disorder and School Environment with Bullying among School Adolescents in Sao Paulo - Brazil.

The role of contextual-level factors in bullying is still not clear, and evidence is mostly from high-income countries. Our objective was to investigate the association between community violence, disorder, school environment and bullying among school adolescents. We used data from a representative sample of 9th grade Brazilian adolescents (n = 2108) from the Sao Paulo Project for the social development of children and adolescents (SP - PROSO). Multilevel logistic regression models stratified by sex were used to assess the association between variables at student and school/neighbourhood level and bullying victimization or perpetration. For both sexes, we found that adolescents who perceived high violence between students and high school disorder were more likely to be bullies and victims. Boys who perceived high community violence and disorder in their neighbourhood were more likely to be bullies (OR3tertile = 2.73 CI95%: 1.57-4.74). Girls attending schools where the principal reported high community violence and disorder in the neighbourhood (ORhigh = 10.24 CI95%: 2.11-49.59) and inside the school (ORhigh = 6.83 CI95%: 1.48-31.56) were more likely to be bullies. Boys from schools whose principal perceived violence between students were less likely to be victims (ORhigh = 0.35 CI95%: 0.16-0.78) and bullies (ORhigh = 0.21 CI95%: 0.07-0.64). Girls attending schools with signs or posters about tolerance/gender equality and about violence were less (OR = 0.12 CI95%: 0.03-0.50) and more likely (OR = 25.88 CI95%: 4.28-156.63) to report being bullies, respectively. Community violence, disorder and school environment were associated with bullying victimization and perpetration among adolescents. Sex-specific associations should be further investigated. Prevention and management of school violence in adolescence should consider contextual-level characteristics.

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.

Association Between Dietary Patterns and Bullying Among Adolescents in Sao Paulo-Brazil.

Previous 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.

Association between parental supervision and bullying victimization and perpetration in Brazilian adolescents, Brazilian National Survey of Student's Health 2015. / Associação entre supervisão parental, vitimização e perpetração de bullying em adolescentes brasileiros, Pesquisa Nacional de Saúde do Escolar 2015.

OBJECTIVE: To analyze the association between parental supervision characteristics and different bullying roles among Brazilian adolescent school students. METHODS: This was a cross-sectional study using data from the National School Student Health Survey (PeNSE) 2015. Frequent meals with parents/guardians, knowing about students' free time activities and checking their homework were the parental practices assessed. Logistic regression was used for association between these practices and bullying (perpetration and victimization), presented as odds ratio (OR) and 95% confidence intervals (95%CI). RESULTS: Among 102,072 school students, frequent meals with parents or guardians [ORvictim = 0.86 (95%CI 0.84;0.89); ORperp = 0.85 (95%CI 0.82;0.88)], checking homework [ORvictim = 0.95 (95%CI 0.92;0.97); ORperp = 0.76 (95%CI - 0.74;0.78)], and parents' or guardians' knowledge about students' free time activities [ORperp = 0.70 (95%CI 0.68;0.73] were inversely associated with bullying. CONCLUSION: Greater parental supervision reduced the odds of bullying victimization and perpetration among adolescent school students.

Social inequality in food consumption between 2008 and 2019 in Brazil.

OBJECTIVE: To analyse the trend of social inequality in food consumption among Brazilians from 2008 to 2019. DESIGN: Time series analyses using cross-sectional annual data from the Telephone Surveillance System (VIGITEL 2008-2019). Food consumption was evaluated through: (1) consumption of five or more portions of fruits and vegetables in ≥5 d/week; (2) consumption of beans in ≥5 d/week and (3) consumption of soft drinks or artificial juices in ≥5 d/week. Absolute inequality was assessed by the slope index of inequality (SII) and relative inequality by the concentration index (CIX). SII and CIX positive values indicate higher prevalence among more educated citizens and negative among less educated ones. Time trend was assessed by linear regression using weighted least squares. SETTING: 26 Brazilian state capitals and the Federal District. PARTICIPANTS: 621 689 individuals ≥18 years. RESULTS: Fruits and vegetable consumption was more prevalent among the more educated citizens, while beans were mostly consumed by the less educated, and soft drinks or artificial juices was more prevalent among individuals with intermediate education. The highest absolute inequality was found for beans (SII2019 -25·9). In 12 years, the absolute inequality increased for fruit and vegetable consumption (from SII2008 12·8 to SII2019 16·2), remained for beans (SII2008 -23·1 to SII2019 -25·9) and reduced for soft drinks or artificial juices (SII2008 8·7 to SII2019 0·4). Relative inequality was low and constant. CONCLUSION: Despite the advances reducing inequalities in soft drinks or artificial juice consumption, the increase in the social gap for adequate consumption of fruits and vegetables is troublesome.

Association between exposure to interpersonal violence and social isolation, and the adoption of unhealthy weight control practices.

OBJECTIVE: To assess the relationship between interpersonal violence, social isolation and unhealthy weight control practices. METHODS: Data on a representative sample of 9th grade Brazilian adolescents from public and private schools (n = 102,072), taken from the National School Health Survey (PeNSE, 2015) were used. The exposures were interpersonal violence (family physical violence, body appearance-related bullying and bullying for the other reasons) and social isolation. The outcomes were unhealthy weight control practices: self-induced vomiting/take laxatives and take any diet pills, powders, or liquids to lose or gain weight/muscle mass without a medical advice. Simple and multiple logistic regression models were performed stratified by sex and adjusted for demographic variables. RESULTS: Family physical violence and social isolation were associated with greater adoption of unhealthy weight control practices, for both sexes. Boy victims of family physical violence were almost twice more likely to adopt unhealthy weight control practices than girls who also suffered this type of violence. Girl victims of body appearance-related bullying adopted more self-induced vomiting/take laxatives (OR 2.29 95%CI 1.87-2.81), take any diet pills, powders, or liquids to lose (OR 1.92 95%CI 1.50-2.46) or gain weight/muscle mass (OR 1.51 95%CI 1.17-1.93). These associations were stronger than those involving other types of bullying. CONCLUSION: Interpersonal violence (family physical violence and bullying) and social isolation were associated with a higher occurrence of unhealthy weight control practices.
