RESUMO
This study is to identify victimization patterns and analyze the association between the experience of polyvictimization 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 São 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 (â: 42.7%, n = 546; â: 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 (â: 29.1%, n = 356; â: 47.9%, n = 652). Class 3 was named high polyvictimization (â: 28.2%, n = 345; â: 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.

The aim was to design culturally acceptable and healthy diets with reduced energetic share of ultra-processed foods (UPF%) at no cost increment and to evaluate the impact of the change in the UPF% on diet quality. Food consumption and price data were obtained from the Household Budget Survey (n 55 970 households) and National Dietary Survey (n 32 749 individuals). Linear programming models were performed to design diets in which the mean population UPF% was reduced up to 5 % with no cost increment relative to the observed costs. The models were isoenergetic or allowed the energy content to vary according to the UPF%, and they were not constrained to nutritional goals (nutrient-free models) or maximised the compliance with dietary recommendations (nutrient-constrained models). Constraints regarding food preference were introduced in the models to obtain culturally acceptable diets. The mean population UPF% was 23·8 %. The lowest UPF% attained was approximately 10 %. The optimised diet cost was up to 20 % cheaper than the observed cost, depending on the model and the income level. In the optimised diets, the reduction in the UPF% was followed by an increase in fruits, vegetables, beans, tubers, dairy products, nuts, fibre, K, Mg, vitamin A and vitamin C in the nutrient-constrained models, compared with the observed consumption in the population. There was little variation in most nutrients across the UPF% reduction. The UPF% reduction in the nutrient-free models impacted only trans-fat and added sugar content. UPF% reduction and increase in diet quality are possible at no cost increment.

OBJECTIVE: To investigate the direct and indirect associations between psychological and physical intimate partner violence and the occurrence of common mental disorders (CMD) and how they relate to the occurrence of household food insecurity (HFI). DESIGN: This was a population-based cross-sectional study. Intimate partner violence was assessed using the Brazilian version of the Revised Conflict Tactics Scale (CTS2) and HFI was assessed using the Brazilian Food Insecurity Scale. The propositional analytical model was based on a review of the literature and was tested using path analysis. SETTING: Duque de Caxias, Greater Rio de Janeiro, Brazil (April-December 2010). SUBJECTS: Women (n 849) who had been in a relationship in the 12 months preceding the interview. RESULTS: Both psychological and physical violence were found to be major risk factors of HFI. Psychological violence was associated with HFI indirectly via physical violence and CMD, and directly by an unidentified path. The effects of physical violence seemed to be manifested exclusively through CMD. Most of the variables in the propositional model related to socio-economic position, demographic characteristics, degree of women's social support and partner alcohol misuse were retained in the 'final' model, indicating that these factors contribute significantly to the increased likelihood of HFI. CONCLUSIONS: The results reinforce the importance of considering domestic violence and other psychosocial aspects of family life when implementing interventions designed to reduce/eradicate HFI.

This study aims to identify the individual community strategies to avoid violence exposure most used by adolescents from public and private schools in the IX Administrative Region of Rio de Janeiro and investigate the profile of co-occurrence and its prevalence in specific population subgroups. This is a cross-sectional study with 693 individuals. A multidimensional questionnaire collected information regarding strategies to avoid community violence exposure and was self-completed in the classroom. The most used strategies were avoiding walking close to armed people (55.5%), avoiding walking alone (30.5%), and avoiding returning home at dawn (24.7%). Girls adopt more of all (concurrently) the four limiting behaviors to reduce their community violence exposure (53% vs. 32%). Notably, the adoption of such strategies differed by socioeconomic indicators and was higher among adolescents from lower-income households. These findings point to the high frequency of use of such strategies by adolescents, which may hinder and limit the full development of their social and cultural skills.
O objetivo do estudo é conhecer as estratégias individuais mais utilizadas por adolescentes de escolas públicas e privadas da IX Região Administrativa do município do Rio de Janeiro para evitar a exposição à violência comunitária, bem como investigar o perfil de coocorrência e sua prevalência em subgrupos populacionais específicos. Trata-se de um estudo seccional com 693 indivíduos. As informações referentes às estratégias para evitar a exposição à violência comunitária foram coletadas por meio de questionário multidimensional autopreenchido em sala de aula. As estratégias mais utilizadas foram: evitar passar onde há pessoas armadas (55,5%), evitar andar sozinho (30,5%) e evitar voltar para casa de madrugada (24,7%). Observou-se que as meninas adotam mais todos (concomitantemente) os quatro tipos de comportamento limitantes para reduzir sua exposição à violência comunitária (53% vs. 32%). Ressalta-se que a adoção de tais estratégias diferiu segundo os indicadores socioeconômicos, sendo maior entre os adolescentes oriundos de família de estratos de renda mais baixos. Tais achados chamam a atenção para a alta frequência de utilização de tais estratégias por adolescentes, o que pode cercear e limitar o pleno desenvolvimento de suas habilidades sociais e culturais.

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.
RESUMO
The aim of this review is to present the state of the art regarding obstetric violence in Brazil. The most commonly used terms are "obstetric violence," "disrespect and abuse," and "mistreatment". Concerning measurement, the most widely used instrument is based on the definition of "mistreatment," still in its early stages of evaluation and lacking adaptation to Brazil. The prevalence of obstetric violence varies widely in national studies due to methodological factors and the type of postpartum women considered. Regarding risk factors, adolescent or women over 35, non-white, with low education levels, users of the public health system (SUS), those who had vaginal birth or abortion, are at higher risk. Hierarchical relationships between the healthcare team and the family are also relevant, as well as inadequate hospital structures, bed shortages, and insufficient healthcare professionals, which contribute to obstetric violence. The consequences of this violence include an increased risk of postpartum depression and PTSD, reduced likelihood of attending postpartum and childcare consultations, and difficulties in exclusive breastfeeding. Interventions to mitigate obstetric violence should consider women's empowerment, healthcare professionals' training, monitoring obstetric violence, and legal support.
O objetivo da revisão é apresentar o estado da arte da violência obstétrica no Brasil. Os termos mais utilizados são "violência obstétrica", "desrespeitos e abusos" e "maus-tratos". Em relação à mensuração, o instrumento mais utilizado é baseado na definição de "Maus-Tratos", ainda em fase inicial de avaliações e sem adaptação para o Brasil. A prevalência da violência obstétrica varia nos estudos nacionais devido a fatores metodológicos e tipo de puérpera. Em relação aos fatores de risco, mulheres adolescentes ou com mais de 35 anos, negras, com baixa escolaridade, usuárias do SUS, com parto vaginal ou aborto estão sob risco. Relações hierárquicas entre equipe de saúde e família também são relevantes, assim como estruturas hospitalares inadequadas, falta de leitos, profissionais de saúde insuficientes, contribuem para a violência obstétrica. As consequências da violência obstétrica são: risco aumentado de depressão e TEPT, menor probabilidade de realizar consultas pós-parto e puericultura e dificuldades para amamentar. Intervenções para mitigar a violência obstétrica devem ser empreendidas considerando o empoderamento das mulheres, a capacitação dos profissionais de saúde, a vigilância da violência obstétrica e o amparo legal.

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.

OBJECTIVE: to analyze the profile of violence against the elderly and the degree of completeness of event notification forms in Niterói, Rio de Janeiro, Brazil. METHODS: this was a descriptive study having as its data source violence notification forms held on the Notifiable Health Conditions Information System for the period 2011-2020; analysis of form completeness was performed according to criteria proposed by the Ministry of Health. RESULTS: of the 486 registered cases, physical violence was the most reported type of violence (48.1%), followed by psychological violence (22.2%) and self-harm (21.4%); the fields with the highest degree of incompleteness were victim's level of schooling (32.8%) and repeat violence (41.5%). CONCLUSION: despite the increase in notifications in the period, predominantly of physical violence, completeness of some of the form fields continues to be poor, which reinforces the importance of training professionals to improve the reporting process and data quality.

Background: Recent literature has shown that many women worldwide are victims of obstetric violence during childbirth. Despite that, few studies are exploring the consequences of such violence on women's and newborn's health. Thus, the present study aimed to investigate the causal association between obstetric violence during childbirth and breastfeeding. Methods: We used data from the study "Birth in Brazil", a national hospital-based cohort of puerperal women and their newborns in 2011/2012. The analysis involved 20,527 women. Obstetric violence was a latent variable composed of seven indicators (physical or psychological violence, disrespect, lack of information, privacy and communication with the healthcare team, inability to ask questions, and loss of autonomy). We worked with two outcomes: 1) breastfeeding at the maternity and 2) breastfeeding 43-180 days after birth. We applied multigroup structural equation modelling, based on the type of birth. Findings: Obstetric violence during childbirth may decrease the probability for women to leave the maternity ward breastfeeding exclusively, having a stronger effect on women who have vaginal birth. Also, being exposed to obstetric violence during childbirth could indirectly affect those women's ability to breastfeed 43-180 days after birth. Interpretation: This research concludes that obstetric violence during childbirth is a risk factor for breastfeeding discontinuation. Such knowledge is relevant so interventions and public policies can be proposed in order to mitigate obstetric violence and provide a better understanding of the context that may lead a woman into discontinuing breastfeeding. Funding: This research was funded by CAPES, CNPQ, DeCiT, and INOVA-ENSP.
RESUMO
OBJECTIVES: To evaluate CADRI's configural and metric structures and explore its performance from the perspective of the respondents as perpetrators and victims. In the process, we present shorter versions for both roles. METHODS: The sample consisted of 561 adolescents aged 15 and 19, enrolled in public and private schools in Rio de Janeiro, Brazil. Initially, confirmatory factor analyzes (CFA) tested the originally proposed dimensional structure. Since this model was rejected, the second step analyzed the data via Exploratory Structural Equation Models (ESEM) to reassess the instrument's structure. Applying a decision algorithm on a new dimensional structure, we proceeded to reduce the number of items to establish separate sets for victimization and perpetration. These final models were then analyzed via CFA to assess their psychometric properties. RESULTS: The final solutions contained 15 items comprising four and three factors for victimization and perpetration, respectively. Thirteen items were common to both models, but two were unique to their respective sets. Regardless of their small differences, the final solutions fitted adequately, held factorial item pertinence and unambiguity, contained reliable and non-redundant items, and sustained factor-based convergent and discriminant validities. CONCLUSION: The four and three-factor models were within the dimensional bounds proposed in the original CADRI, the shorter scales still succeeding in partially capturing what was envisaged in the first version of the instrument. However, the shorter versions suggested here are still tentative, thus requiring further examination.

This study aimed to estimate the prevalence of sexual initiation of pupils aged 10 to 14 who attended the second year of public and private high school in the IX Administrative Region of the city of Rio de Janeiro, Brazil and to identify the most vulnerable subgroups. The sample consisted of 694 pupils who were selected through cluster-based and stratified sampling by considering school type (public or private) and course type (daytime or evening). Information was collected by means of a structured self-administered questionnaire. The chi-square test (χ2) and 95% confidence intervals were used to assess the heterogeneity of proportions among subgroups. The prevalence of the event was 18.4%; it was higher in boys, in subgroups of greater social vulnerability, among those who hooked up/dated up to 14 years of age, in victims of sexual violence in affective-sexual relationships and in pupils showing health risk behaviors. The high rate of sexual initiation in early adolescence, especially in more vulnerable groups, shows that the situation must be understood and addressed by means of intersectoral public policies that take into account a social context of multiple needs rather than reproductive health alone.
O objetivo do estudo foi estimar a prevalência de iniciação sexual entre 10 e 14 anos, em estudantes do segundo ano do ensino médio da rede pública e privada da IX RA do município de Rio de Janeiro-RJ, e identificar subgrupos mais vulneráveis à situação. A amostra foi composta por 694 estudantes, selecionados através de uma amostragem por conglomerados e estratificada por turno de aula e características administrativa da escola. As informações foram coletadas através de questionário estruturado de autopreenchimento. Intervalos de confiança a 95% e o teste Qui-Quadrado (χ2) foram usados para avaliar a heterogeneidade das proporções entre subgrupos. A prevalência do evento foi 18,4%, sendo maior: em meninos; em subgrupos de maior vulnerabilidade social; entre os que ficaram/namoraram até 14 anos; os que foram vítimas de violência sexual em relacionamentos afetivo-sexuais; e os que apresentaram comportamentos de riscos à saúde. A alta frequência de iniciação sexual na adolescência precoce, especialmente em grupos mais vulneráveis, evidencia que a situação deve ser compreendida e enfrentada com políticas públicas intersetoriais que leve em consideração um contexto social de múltiplas carências e não apenas à saúde reprodutiva.

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.

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.
RESUMO
Research focusing on the relationship between interpersonal violence and nutritional status in adolescence is scarce and has distinct results. The objective of this study is to investigate the association of family physical and sexual violence with inadequate nutritional status in Brazilian adolescents. We used data from the 2015 Brazilian National Survey of School Health. This study includes 11.850 students, older than 13 years, attending from sixth to ninth grade of elementary school and from the 1st to the 3rd year of high school. The exposures were family physical violence and rape. The outcome was nutritional status, assessed through body mass index. The association between exposures and outcome were investigated using a multinomial logistic regression model. These analyses were adjusted for demographic, socioeconomic, and family variables. The prevalence of family physical violence victimization was approximately 14% among adolescents for both sexes. The prevalence of rape was 4.6% and 5.7% among male and female adolescents, respectively. Family physical violence was not associated with being underweight, overweight, or obese, in either crude or adjusted models for both sexes. Sexual violence was inversely associated with being underweight only for male adolescents (OR: 0.21, CI 95%: 0.06-0.75). In female adolescents, sexual violence was associated with overweight/obesity (OR: 1.64, CI 95%:1.15-2.33). In this study, rape, but not family physical violence victimization, was associated with nutritional status in adolescents of both sexes. Nonetheless, this association was different between boys and girls. Rape was inversely associated with being underweight in male adolescents, whereas, in female adolescents, it was associated with excess body weight.

Studies on disrespect and abuse/mistreatment/obstetric violence during pregnancy, childbirth and puerperium have increased in recent decades. However, researchers interested in the subject face many theoretical and methodological difficulties. In this sense, this study aims to discuss and reflect on how issues related to definition and terminology, measurement, and public policies in Brazil have hindered research on this topic and the mitigation of these acts. The first problem addressed was the lack of consensus regarding the terminology and definition of this construct. This situation causes a cascading effect, impacting the use of non-validated measurement instruments and, consequently, a lack of accuracy and comparability between studies. Another issue mentioned is the lack of studies exploring the consequences of these acts on women's and newborn's health, which is one of the main gaps on the subject today. The absence of causal studies affects health decision-making, impairing the elaboration of specific public policies.
Estudos sobre desrespeitos e abusos/maus tratos/violência obstétrica durante gestação, parto e puerpério têm aumentado nas últimas décadas. Entretanto, os pesquisadores interessados na temática se deparam com muitas dificuldades teóricas e metodológicas. Nesse sentido, o objetivo do presente estudo consiste em discutir e refletir sobre como questões relacionadas a definição e terminologia, mensuração e políticas públicas no Brasil têm dificultado a pesquisa da temática, assim como a mitigação desses atos. O primeiro problema abordado foi a falta de consenso em relação a terminologia e definição desse construto. Essa situação provoca um efeito em cascata, com a utilização de instrumentos de aferição não validados que implicam falta de precisão e comparabilidade entre os estudos. Outra questão mencionada é a falta de estudos explorando as consequências desses atos na saúde da mulher e do recém-nascido, configurando uma das principais lacunas sobre o tema atualmente. A ausência de estudos causais impacta a tomada de decisão em saúde, prejudicando a elaboração de políticas públicas específicas.

OBJECTIVE: To assess the effect of modifications of the school environment on physical activity in Brazilian adolescent students. METHODS: Seven public schools in Duque de Caxias (Brazil) were randomized into control and intervention groups. The intervention group underwent modifications in the school environment (painting of hopscotch and school courts) and the provision of sports equipment (balls, basketball table, soccer goalpost, volleyball nets, and others) to stimulate physical activity. Additionally, footsteps towards the court and materials were painted, and a superhero character called Super Active was introduced. Total physical activity was measured using a validated questionnaire for adolescents. Generalized linear models were used to evaluate the effect of the intervention, adjusted by sex. RESULTS: The sample consisted of 975 adolescents, with a mean age of 11.52 years (standard deviation - SD 1.43), and 56.7% were boys. After the one-month intervention, both groups' total physical activity time increased. The estimated changes from baseline were not different between the intervention and control groups (Δ=102.75 and Δ=99.76, respectively; p=0.52). CONCLUSION: The painting, supply of equipment and other strategies to encourage physical activity in the school environment did not promote a positive effect on improving physical activity among adolescents. Future research is necessary to evaluate the effect of the intervention in the long-term period, particularly in other population contexts in middle-income countries.

BACKGROUND: The mistreatment of women during pregnancy, childbirth, and the puerperium is a global public health problem besides being a violation of human rights. However, research exploring the consequences of mistreatment of women and newborns is scarce. QUESTION: To shed light on this issue, we investigated the association between the mistreatment of women during childbirth and the subsequent use of postnatal health services by women and their newborns. METHODS: We used data from the study "Birth in Brazil", a national hospital-based survey of puerperal women and their newborns, carried out in 2011/2012. This analysis involved 19,644 women. Mistreatment was a latent variable composed of seven indicators. We assessed the attendance of women and newborns to a review consultation following birth, and the timing of this appointment. We applied multigroup structural equation modeling (based on childbirth payment source) and considered separate analysis for women (vaginal births and0 caesarean-sections) and newborns. FINDINGS: We found a causal association between mistreatment during childbirth and decreased and/or delayed use of postnatal health services, for both women and their newborns. These results also revealed that women who use the public sector are affected more than those who pay for private healthcare. CONCLUSION: Mistreatment during childbirth has broader implications than "maternal mental health", and it would be useful to understand that experience of care has vast implications for families. In Brazil, the mistreatment must be mitigated via the implementation of public policy. This is part of the path to dignified and respectful childbirth care for all women.

We present results of initial steps of the psychometric evaluation of a proposed modified version of the Brazilian Household Food Insecurity Measurement Scale aimed at assessing adults' recall of food insecurity at age 12. Data were obtained through self-administered questionnaires from civil servants at university campuses in Rio de Janeiro, who participated in the first and fourth waves of the longitudinal Pró-Saúde Study. We evaluated test-retest reliability (n=58), internal consistency, factor structure, convergent, discriminant validity (n=3,253). Test-retest reliability kappa coefficients were above 0.65; Cronbach's α coefficient was 0.84. Factor loadings were above 0.800. The composite reliability was above 0.90. The square root values of the Average Variance Extracted were positive and statistically significant. Household food insecurity during childhood was strongly associated with larger family size and several sociodemographic conditions at age 12: female head of household, residence in rural area or small town, worse standard of living, and insufficient food due to lack of money. This initial evaluation suggests good performance. Further investigation should include additional psychometric properties and other population contexts.

Although recent studies have related the occurrence of violence in childhood and adolescence with the adoption of health risk behaviors, there are no studies that quantify this co-occurrence among adolescent victims of family violence. Our objective was, therefore, to investigate the co-occurrence of health risk behaviors in these adolescent victims. Data from the National School Health Survey, collected in 2015, were used. Co-occurrence of risk behaviors-involvement in fights, substance use (alcohol, drugs, and tobacco), not wearing seat belts and helmets, inadequate food consumption-was analyzed using Venn diagrams, according to the victim's status and sex. The association between the four risk behaviors and victimization was investigated using multiple logistic regression. All the analyses were performed using Stata®13. We found an excess of risk behaviors among victims of family violence in both sexes. The co-occurrence of the four risk behaviors analyzed was higher among male and female adolescents, who were victims of family violence than in nonvictims. Family violence was associated with the adoption of risk behaviors, regardless of sex. This association was stronger as the number of risk behaviors adopted increased. The chance of engaging in one risk behavior was 1.32 (95% confidence interval (CI) = [0.88, 1.98]) and 1.24 (95% CI = [0.90, 1.72]) higher for boys and girls, respectively, who had suffered family violence. This increased to 7.76 (95% CI = [5.33, 11.29]) and 7.28 (95% CI = [5.20, 10.20]) when considering engagement in four risk behaviors. Identifying the prevalence of co-occurrence of health risk behaviors in vulnerable subgroups (such as victims of domestic violence) could help target broader interventions focusing on multiple risk behaviors.
