- Abstract
OBJECTIVE: To analyze the association between police violence and homicide mortality rates taking into consideration the effect of contextual variables. METHODS: This was an environmental, cross-sectional study that included the 96 census districts in the City of Sao Paulo. The association between the variables was analyzed using Spearman's rank correlation and simple and multiple regression analysis. RESULTS: Univariate analysis revealed a strong and significant association between homicide mortality coefficients and all the indicators of socioeconomic development and police violence. After controlling for potential confounding factors, the association between police violence and homicide mortality coefficients remained strong and significant. This significance was lost only after control for the size of the resident population. CONCLUSION: The results indicate that police action that violates basic human rights is not the right answer to urban violence. The combination of homicides from interpersonal violence and deaths from police violence results in negative socialization and promotes further violence. [ABSTRACT FROM AUTHOR]

- Abstract
Objective: To evaluate whether adolescents from sexual minorities who initiated pre-exposure prophylaxis (PrEP) in community-based organizations (COs) are more socially and HIV-vulnerable compared with their counterparts from a conventional health service. In addition, to evaluate whether these adolescents had more timely access to prophylaxis., Methods: A PrEP demonstration study was conducted in the city of São Paulo in two COs, located in the center (CO-center) and the outskirts (CO-outskirts), and a conventional HIV testing service (CTA-center). Between 2020 and 2022, cisgender male adolescents who have sex with men (aMSM), transgender and gender diverse adolescents (aTTrans) aged 15 to 19 years, HIV-negative, with higher-risk practices for HIV were eligible for PrEP. Indicators of timely access and vulnerabilities of adolescents initiating PrEP in COs were analyzed using CTA-center as a reference and multinomial logistic regression., Results: 608 adolescents initiated PrEP in COs and CTA-center. Adolescents from COs were associated with a shorter time to PrEP initiation (1-7 days; CO-outskirts: ORa = 2.91; 95%CI 1.22-6.92; CO-center: ORa = 1.91; 95%CI 1.10-3.31); and a lower housing Human Development Index (HDI) (CO-center: ORa = 0.97; 95%CI 0.94-1.00; CO-outskirts: ORa = 0.82; 95%CI 0.78-0.86). In CO-outskirts, there was an increased chance of adolescents being younger (ORa = 3.06; 95%CI 1.63-5.75) and living closer to the service (ORa = 0.82; 95%CI 0.78-0.86, mean 7.8 km). While adolescents from the CO-center were associated with greater prior knowledge of PrEP (ORa = 2.01; 95%CI 1.10-3.91) and high-risk perception (ORa = 2.02; 95%CI 1.18-3.44), adolescents from the COs were not associated with higher-risk sexual practices and situations of vulnerability to HIV., Conclusion: The provision of PrEP in the COs facilitated access for vulnerable adolescents and may contribute to reducing inequities.

- Abstract
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., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Okada, Marques, Levy, Gonçalves, Peres and Azeredo.)

- Abstract
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., Competing Interests: Declaration of Conflicting InterestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

- Abstract
The HIV epidemic has a disproportionate impact on adolescent and young men who have sex with men (AMSM) and transgender women and travestis (ATGW), with an increased HIV prevalence over the last 10 years. Violence affects the lives of these populations, undermining their ability to self-care and making them more vulnerable to HIV infection. In this study, we aimed to examine the association between different types of victimization by violence and discrimination and sexual health practices of these adolescent populations in steady and casual relationships. We conducted a cross-sectional study using baseline data from the cohort of PrEP1519 project. We used the mean score of sexual health practices as our outcome and the cumulative score of discrimination (within family, community, education, religious, online and public spaces) and violence (physical, sexual and intimate partner) as our exposure variable. We performed linear regression analyses to estimate the association between exposure and outcome. We found that 90% of AMSM and 95% of ATGW experienced at least one form of violence in the three months prior to this study and about 45% of ATGW suffered sexual violence during the same period. Experiencing discrimination within healthcare settings (from facilities or providers) was negatively associated with sexual health practices. Discrimination and violence negatively affect sexual health practices. HIV prevention and care of AMSM and ATGW people should involve listening to their experiences and addressing discrimination and violence in this population.

- Abstract
Introduction: Pre-exposure prophylaxis (PrEP) delivery based on user needs can enhance PrEP access and impact. We examined whether telehealth for daily oral PrEP delivery could change the indicators of care related to prophylactic use in five Brazilian public HIV clinics (testing centres, outpatient clinics and infectious disease hospitals)., Methods: Between July 2019 and December 2020, clients on PrEP for at least 6 months could transition to telehealth or stay with in-person follow-up. Clients were clinically monitored until June 2021. A desktop or mobile application was developed, comprising three asynchronous consultations and one annual in-person consultation visit. Predictors influencing telehealth preference and care outcomes were examined. The analysis encompassed intent-to-treat (first choice) and adjustments for sexual practices, schooling, age, duration of PrEP use and PrEP status during the choice period., Results: Of 470 users, 52% chose telehealth, with the adjusted odds ratio (aOR) increasing over time for PrEP use (aOR for 25-months of use: 4.90; 95% CI: 1.32-18.25), having discontinued PrEP at the time of the choice (aOR: 2.91; 95% CI: 1.40-6.06) and having health insurance (aOR: 1.91; 95% CI: 1.24-2.94) and decreasing for those who reported higher-risk behaviour (aOR for unprotected anal sex: 0.51; 95% CI: 0.29-0.88). After an average follow-up period of 1.6 years (95% CI: 1.5-1.7), the risk of discontinuing PrEP (not having the medication for more than 90 days) was 34% lower with telehealth (adjusted hazard ratio: 0.66; 95% CI: 0.45-0.97). When adjusted by mixed linear regression, no differences in adherence (measured by mean medication possession rate) were found between in-person and telehealth (p = 0.486) or at pre- and post-telehealth follow-ups (p = 0.245). Sexually transmitted infections increased between the pre-follow-up and post-follow-up choices and were not associated with in-person or telehealth (p = 0.528). No HIV infections were observed., Conclusions: Our findings indicate that telehealth for PrEP delivery can enhance service rationalization and reinforce the prevention cascade. This approach reduces prophylaxis interruptions and is mainly preferred by individuals with lower demands for healthcare services., (© 2023 The Authors.

- Abstract
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 (♀: 42.7%, n = 546; ♂: 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 (♀: 29.1%, n = 356; ♂: 47.9%, n = 652). Class 3 was named high polyvictimization (♀: 28.2%, n = 345; ♂: 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 (OR
adj : 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., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper.

- Abstract
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 (OR
3tertile = 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.- Published

- Abstract
Intersectionality is a useful tool to address health inequalities, by helping us understand and respond to the individual and group effects of converging systems of power. Intersectionality rejects the notion of inequalities being the result of single, distinct factors, and instead focuses on the relationships between overlapping processes that create inequities. In this Series paper, we use an intersectional approach to highlight the intersections of racism, xenophobia, and discrimination with other systems of oppression, how this affects health, and what can be done about it. We present five case studies from different global locations that outline different dimensions of discrimination based on caste, ethnicity and migration status, Indigeneity, religion, and skin colour. Although experiences are diverse, the case studies show commonalities in how discrimination operates to affect health and wellbeing: how historical factors and coloniality shape contemporary experiences of race and racism; how racism leads to separation and hierarchies across shifting lines of identity and privilege; how racism and discrimination are institutionalised at a systems level and are embedded in laws, regulations, practices, and health systems; how discrimination, minoritisation, and exclusion are racialised processes, influenced by visible factors and tacit knowledge; and how racism is a form of structural violence. These insights allow us to begin to articulate starting points for justice-based action that addresses root causes, engages beyond the health sector, and encourages transnational solidarity., Competing Interests: Declaration of interests DD is the co-founder and lead of the Race & Health collective within UCL.

- Abstract
Objective: 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: São Paulo, SP, Brazil., Participants: A total of 2680 students, M
age = 14·85; (95 % CI 14·81, 14·88)., Results: UPF consumption was associated with higher scores in IS in the crude ( β = 0·14; P < 0·001) and adjusted ( β = 0·12; P < 0·001) 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.- Published

- Abstract
The role of the school in promoting health and preventing diseases among children and adolescents has long been recognized. Among the characteristics of schools with effects on health, child development, learning and school performance, the international literature has highlighted the school climate. However, in Brazil, relatively little research has been done in this field to date. In view of this scenario, this study aimed to describe the characteristics of Brazilian research into the school climate, paying special attention to the methods of measurement, to themes related to it and to research on the relationship between school climate and health in Brazil. To this end, we conducted a scope review with Brazilian theses and dissertations since 1987. The results showed the predominance of qualitative studies, with data from few schools, a wide variety of strategies and instruments used to measure the climate, with emphasis on the use of questionnaires, scales and interviews. There was also a relatively small participation of the health field, especially with regard to student health.

- Abstract
The scope of this study is to understand how State Public Security Plans (PSP) incorporate the perspective of violence prevention and intersectorality, with special attention to the role of the health sector. It is a qualitative study that used the techniques of document and content analysis, having the PSP either implemented or in the formulation stage as empirical material. A total of 14 PSP were identified. All plans incorporate the concepts of violence prevention, intersectorality and participation of the health sector. The concept of violence prevention stems from the concept of citizen security, but specific prevention actions are mentioned in a generic way. The incorporation of intersectorality is heterogeneous and insufficient, to the extent that the participation of sectors in the planning phase is not the rule. The participation of the health sector is not always active, that is, from the planning phase of the actions, which, most of the time, are timely and care-based. The health sector also assumes a secondary role, without its experience and potential being recognized. Conceptions of violence prevention, intersectorality and participation of the health sector are present in the plans in an incipient way. The importance of new studies is emphasized.

- Abstract
Background: Adolescents in low-resource urban settings in Brazil are often exposed to high levels of trauma that can result in post-traumatic stress disorder (PTSD). However, preliminary evidence indicates that PTSD tends to be under-reported in Brazilian health services, despite the high prevalence of trauma. Additionally, little is known about the perceived applicability among clinicians of the new ICD-11 diagnosis of complex PTSD (CPTSD), despite its potential relevance for contexts of chronic trauma. The current study investigated local understandings of PTSD and CPTSD among health professionals working with adolescents in violent neighbourhoods of São Paulo city., Methods: Semi-structured interviews were conducted with 58 health professionals working at both the primary care and specialized mental health levels in two areas of São Paulo city with high levels of community violence., Results: Most participants knew about PTSD, but most did not know about CPTSD. There were mixed views concerning the commonality of PTSD among adolescents exposed to community violence. Many participants reported having no experience working with patients with the PTSD diagnosis. According to some, community violence was normalized by adolescents and health professionals, and did not result in PTSD. Others highlighted how they did not use psychiatric diagnoses in their practice, had critical perspectives towards psychiatric diagnoses and/or PTSD, or simply knew little about PTSD. Furthermore, many highlighted how the chronic nature of multiple traumas experienced by adolescents often resulted in complex clinical presentations characterised by many symptoms beyond PTSD. The diagnosis of CPTSD was considered appropriate to the context by many participants as it captured the complex traumatic histories and symptom presentations of adolescents exposed to community violence in Brazil., Conclusions: These findings have important implications for the assessment and treatment of mental health among adolescents exposed to community violence in Brazil., (© 2022.

- Abstract
Ultra-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 São 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: 0.55; 1.09), and sugary drinks (0.34; 95%CI: 0.06; 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.

- Abstract
Although São Paulo is the most populous city in Brazil - one of the world's most violent countries - a significant reduction in its homicide mortality rate (HMR) has been detected. This study aims to estimate the effects of age, period, and birth cohort on the trend of homicide mortality according to sex in the city of São Paulo, from 1996 to 2015. An ecological study was undertaken with data on deaths by homicide for both sexes, in all age brackets, in the city of São Paulo. Poisson models were adjusted for each sex to estimate the age-period-cohort effects. In total, 61,833 deaths by homicide were recorded among males and 5,109 among females. Regardless of the period, the highest HMR occurred in the 20-24 age bracket. Higher HMRs were found in those born in the 1970s and 1980s. The complete model, with age-period-cohort effects, were the best fit to the data. The risk of death by homicide declined over the periods, with lower intensity in the final five years (2011-2015), for both males (RR = 0.48; 95%CI: 0.46; 0.49) and females (RR = 0.52; 95%CI: 0.47; 0.57). A reduction was found in the risk of homicide, regardless of the sex or age bracket, and also in recent cohorts. However, the intensity of such reductions has been decreasing over time, which suggests that the public policies adopted have limited potential to maintain these achievements.

- Abstract
Deadly police force is a public health problem. Although the Mortality Information System (SIM) is the most reliable record of deaths from violence, the same is not true for cases of deadly police force, which displays a high degree of underreporting when compared to data from the São Paulo Department of Law Enforcement (SSP-SP). The current study aimed to estimate underreporting in the two official data sources (SIM and SSP-SP), identifying the ICD-10 categories used in cases of incorrectly classified deadly police force and mortality rates in the years 2014 and 2015 in the city of São Paulo, Brazil. Using linkage of data from the SIM and SSP-SP databases, we describe the use of underlying causes of death in cases of deadly police force, estimating underreporting in the SIM and the SSP-SP with the capture-recapture methodology and mortality rates in the city. Based on the database linkage, most of the deaths from deadly police force were classified incorrectly (53%) as other underlying causes of death in the SIM. Both the SIM and SSP-SP underreported the deaths committed by police officers, with different magnitudes (53.2% in the SIM and 7.9% in the SSP-SP). Reclassification of the deaths via linkage added a gain in the SIM, which now had the same mean mortality rate as the SSP-SP (3.44/100,000), thereby decreasing the underreporting in comparison to the initial scenario. Correct recording of death is the first step to the ensuring the right to justice and truth. Recording with quality means to guarantee the right to information, which is not an end per se, but the start in the task of prevention. Data-sharing and inter-sector work are urgently needed.

- Abstract
Background: Self-control (SC) has been consistently found associated with diverse health risk behaviors (HRBs), but little research refers to low- and middle-income countries. Furthermore, there is evidence that some HRBs tend to aggregate, however studies with the specific purpose of addressing the relation between SC and multiple health risk behaviors (MHRBs) are rare. The objective of this study is to analyze these associations and provide evidence to help filling these gaps., Methods: A sample of 2106 9th grade students from the city of São Paulo responded a self-administered questionnaire in 2017. We tested the association of SC measured as an ordinal variable with four levels (higher, high, medium and low) with six HRBs (binge drinking, marijuana use, smoking, high consumption of ultra-processed food, sedentary behavior and bullying perpetration), in both separated and aggregated forms (MHRBs), controlling for potential confounders. Binary logistic regression was used to test the association between exposure (SC) and single outcomes. In order to analyze the association of SC with MHRBs, multinomial logistic regression was employed., Results: SC was associated with five of six HRBs investigated and with MHRBs. The effect size of the association of SC and MHRBs increased in a steep pattern with accumulation of more HRBs., Conclusion: Low self-control is associated with most HRBs investigated and the magnitude of the association increases when more than two or three HRBs are accumulated. There seems to be a group of adolescents in a position of pronounced vulnerability for MHRBs. This should be considered when designing public policy and prevention programs. In contexts of limited or scarce resources and public funds, interventions focusing the most vulnerable groups, instead of universal interventions, should be considered., (© 2021. The Author(s).)

- Abstract
We examined the association of physical activity (PA) facilities and access to school with total PA and domain-specific PA in adolescents. We enrolled 2610 adolescents (mean: 14.9 years) from Sao Paulo city. The number and presence of sports courts, swimming pools, locker rooms, running/athletics tracks, entrance accessible for student cyclists, bike racks, speed limit signal around the school, and pedestrian crossing were assessed in each school. All participants responded to a questionnaire about frequency and duration of physical education classes, leisure time, and active commuting. Total PA was obtained by adding up all PA domains. Presence of three or more (OR: 1.62; 95% CI: 1.15 to 2.30) sports courts, swimming pool available in usable conditions (OR: 1.45; 95% CI: 1.01 to 2.10), running/athletics tracks (OR: 2.35; 95% CI: 1.07 to 5.18), and bike racks (OR: 1.38; 95% CI: 1.07 to 1.78) were positively associated with total PA. Number of sports courts, swimming pool available in usable conditions, speed limit signals around the school, and pedestrian crossings were positively associated with physical education classes. The bike racks, speed limit signs around the school, and pedestrian crossings were positively associated with active commuting. School environment was associated with increased PA. Our findings should be considered in future epidemiologic studies and for educational and health policy makers., (© 2021. The Author(s).)

- Abstract
We aimed to investigate how lethal police violence (LPV) in the City of São Paulo (CSP), Brazil, is associated with socioeconomic development when we consider the victims' place of residence and the locations of the fatal injuries. The spatial distribution of lethal police violence rate (LPVR) and its association with the human development index (HDI) was investigated using the Moran's I (Global and Bivariate Local). Between 2014 and 2015 we found 403 police victims in the Health database and 794 victims in the Security Department. We found a non-random spatial distribution of the LPV considering the victim's place of residence (I=+0.12; p<0.001) and the locations where the fatal injuries were inflicted (I=+0.07; p<0.001). We found a negative association between LPVR and the HDI of the place of residence (I=-0.10; p<0.001) and a positive association between LPVR and the HDI of the locations of the fatal injuries (I=+0.02; p<0.001). The results point to different dynamics of LPV in CSP. High mortality clusters are found in areas with lower HDI, when considering the victim's address, and in areas with higher HDI, when considering the address of the violent events. LPV impacts young blacks, poorly educated residents of outskirts informing us about patterns of social segregation.

- Abstract
The stay-at-home restrictions to control the spread of COVID-19 led to unparalleled sudden change in daily life, but it is unclear how they affected urban crime globally. We collected data on daily counts of crime in 27 cities across 23 countries in the Americas, Europe, the Middle East and Asia. We conducted interrupted time series analyses to assess the impact of stay-at-home restrictions on different types of crime in each city. Our findings show that the stay-at-home policies were associated with a considerable drop in urban crime, but with substantial variation across cities and types of crime. Meta-regression results showed that more stringent restrictions over movement in public space were predictive of larger declines in crime., (© 2021. The Author(s).)

- Abstract
Objectives: To estimate the prevalence of self-reported bullying as victims, bullies or bully-victims among 9th grade adolescents in the city of São Paulo, Brazil; to investigate association between bullying with negative health outcomes., Methods: Cross-sectional data were obtained in 2017 from a sample of Brazilian adolescents (n = 2680) using a structured, self-administered questionnaire. Bivariate and multivariate Poisson regression were employed to assess in which extent the experience of bullying in position of victim, bully or bully-victim affects adolescents' health., Results: Prevalence of bullying victimization was 18.3%, while victimization/perpetration and perpetration corresponded to 10.42% and 4.9%, respectively. Adolescents who experienced bullying victimization were more likely to present high levels of internalizing symptoms, to report self-harm, to present negative self-rated health and to use tobacco, when compared with those not involved. Bullies were more likely to use alcohol and to binge drinking. bully-victims presented a higher prevalence of all health outcomes, except for tobacco use., Conclusions: Our findings highlight the effect of bullying in adolescents' health, regardless of the position. Planned intersectoral efforts between parents, health and education systems to prevent bullying could therefore reduce negative health outcomes during adolescence.

- Abstract
Objectives: We examined the patterns of total and domain-specific physical activity (PA) by sex, socioeconomic status and maternal education level in adolescents from Sao Paulo city, Brazil., Design: Cross-sectional study., Participants: We included a representative sample of 2682 (52.2% boys) adolescents aged 14-15 years from public and private schools in Sao Paulo, 2017. Socioeconomic status was assessed using a wealth index derived from principal component analysis. Descriptive analyses evaluated differences in total and domain-specific PA by sex, socioeconomic status and maternal education level., Outcome Measures: We collected data on the frequency and duration that adolescents spent in each PA domain (active transportation, leisure PA and physical education classes) through a self-report questionnaire., Results: On average, adolescents spent 197.7 min/week (95% CI 190.6-204.8) in total PA. The proportion of adolescents achieving at least 60 min/day (≥420 min/week) was 12.7% (95% CI 11.4-14.1), with a higher prevalence in boys (18.3%) and in those with higher socioeconomic status (17.4%). Similar patterns were observed for leisure PA and physical education classes. Active transportation was higher in girls (46.0 min/week; 95% CI 42.6-49.6) than in boys (43.4 min/week, 95% CI 39.9-46.6). Boys and adolescents with higher socioeconomic status and higher maternal education level had higher levels of total PA., Conclusions: We found a variation in patterns of total and domain-specific PA by sex, socioeconomic status and maternal education level in adolescents from Sao Paulo. Initiatives for promoting PA in adolescents should take these findings into account., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2020.

- Abstract
Introduction: The isolated negative impacts of community violence and family violence on individuals' self-rated health (SRH) are known, but there is little evidence on the combined effect of these two types of interpersonal violence., Objective: To analyze the association between exposure to community violence/by strangers and family violence/by acquaintances and negative SRH, distinguishing the type of violence suffered and also considering its cumulative exposure., Methods: Epidemiological cross-sectional study developed with data from the National Health Survey (PNS) 2013. Crude multinominal logistic regression models were performed and adjusted to test the association of variables., Results: All types of violence analyzed were associated with negative SRH. Isolated community/unknown interpersonal violence was associated with SRH as regular (odds ratio - OR = 1.38) and bad (OR = 1.79). Exposure to family violence/by acquaintances was associated with regular (OR = 1.52) and bad (OR = 2.70) self-assessment. Concomitant exposure to the two types of violence was associated with regular (OR = 4.00) and bad (OR = 7.81) health assessments, with this association being of greater magnitude than those for isolated violence., Conclusion: The cumulative effect of exposure to family/known and community/unknown violence enhances the negative assessment of health status. Health professionals must be aware of the multivitaminization and its impact on the health of victims who access health services.

- Abstract
This study analyzes time trends in verbal bullying, domestic violence, and involvement in fights with firearms among adolescents in Brazilian state capitals from 2009 to 2015. The study of trends uses data from the Brazilian National Survey of School Health (PeNSE) in 2009, 2012, and 2015 among ninth-graders enrolled in public and private schools in the country's 26 state capitals and the Federal District. The analysis focused on domestic violence, verbal bullying, and involvement in fights with cold steel weapons and firearms in the 30 days prior to the interview. Logistic regression was performed, adjusted for sociodemographic and behavioral characteristics, with analysis of each type of violence in Brazil and in the capital cities, according to sex. The trends were spatialized. For the capital cities as a whole, from 2009 to 2015 there was an increase of 12% (95%CI: 1.11-1.14) in domestic violence, 10% (95%CI: 1.08-1.11) in verbal bullying, and 7% (95%CI: 1.05-1.09) and 7% (95%CI: 1.05-1.08) in involvement in fights with firearms and cold steel weapons, respectively. Domestic violence increased in all the capital cities. In 96.3%, 70.4%, and 62.9% of the capital cities, respectively, there were increases in verbal bullying and involvement in fights with cold steel weapons and firearms, while there were stationary trends in the other capital cities. There was an upward trend in these forms of violence in the majority of the capital cities, evidencing the need to implement public policies to mitigation the different types of violence among adolescents.

- Abstract
Objectives: To investigate the association between personal, relational and school factors with involvement in fights with weapon among Brazilian school-age youth., Methods: Using data from the Adolescent School-Based Health Survey 2015 (n = 102.072), we conducted multilevel logistic regression models., Results: IFW was associated with female sex (OR = 0.45), and with older age (OR = 1.15), previous involvement in physical violence (OR = 2.05), history of peer verbal (OR = 1.14) and domestic victimization (OR = 2.11), alcohol use (OR = 2.42) and drug use (OR = 3.23). The relational variables (e.g., parent's supervision) were mostly negatively associated with IFW. At the school level, attending public school and attending schools in violent surroundings were both positively associated with IFW. The intraclass correlation coefficient estimated in the empty model showed that 5.77% of the variance of IFW was at school level. When all individual- and school-level variables were included in the model, the proportional changes in variance were 61.7 and 71.55%, respectively., Conclusions: IFW is associated with personal, relational and school factors. Part of the variance in IFW by school is explained by characteristics of the school context.

- Abstract
Since the 1990s, researchers have noted declining trends in crime and violence, particularly homicide, in Western countries. Studies have explored national and sub-national trends using latent trajectory analysis techniques and identified several factors associated with declining and/or increasing trajectories. Social disorganization (SD) has been consistently linked to increases in homicide rates over time, explaining at least some of the spatial and temporal heterogeneity of homicide. Similar studies have not yet been carried out in Latin America's cities. In this paper we use Group Based Trajectory models to study homicide mortality rate [HMR] trajectories in Brazilian municipalities between 1991 and 2010. Then, through binary and multinomial logistic regression we investigated the association between SD in 1991, and the likelihood of an increasing HMR trajectory. We carried out an ecological time series study using all Brazilian municipalities in the period between 1991 and 2010 (n = 4491). Data on homicide deaths were collected from the Mortality Information System of the Ministry of Health and standardized by age to calculate HMR per 100,000 population. Socioeconomic and demographic data for 1991 were used to compose the composite measure of SD. Our results highlight the spatial and temporal heterogeneity of homicide mortality in Brazilian municipalities. While national trends are steadily increasing, disaggregating municipal trajectories shows that this is driven by a small proportion of municipalities in the country. We found that SD is associated with an ascending homicide trajectory. This result generally supports the notion that poor social structural conditions can create 'space' for criminal behavior and groups and, consequently, violent death., (Copyright © 2017 Elsevier Ltd.
