- Effects of age, period, and birth cohort on homicide mortality in the city of Sao Paulo, Brazil, from 1996 to 2015(2022) ANDRADE, Flavia Reis de; MENEZES, Fabricio dos Santos; OLIVEIRA, Max Moura de; CONCEICAO, Gleice Margarete de Souza; PERES, Maria Fernanda Tourinho; LATORRE, Maria do Rosario Dias de OliveiraAlthough Sao 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 Sao 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 Sao 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.
- Trends in verbal bullying, domestic violence, and involvement in fights with firearms among adolescents in Brazilian state capitals from 2009 to 2015(2019) SILVA, Aline Natalia; MARQUES, Emanuele Souza; PERES, Maria Fernanda Tourinho; AZEREDO, Catarina MachadoThis 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 fir 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: 1.111.14) 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 629% 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.
- Violence, discrimination, and sexual health practices among adolescent men who have sex with men, transgender women and travestis in three cities in Brazil(2023) RYNGELBLUM, Marcelo; GRANGEIRO, Alexandre; ZUCCHI, Eliana Miura; COUTO, Marcia Thereza; DOURADO, Ines; MAGNO, Laio; TUPINAMBAS, Unai; PERES, Maria Fernanda TourinhoThe 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 discrimi-nati on (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. Discrimi-nation and violence negatively affect sexual health practices. HIV prevention and care of AMSM and ATGW people should involve listening to their experi-ences and addressing discrimination and violence in this population.
- 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.
- Data quality analysis of deaths committed by the police in the city of Sao Paulo, Brazil, 2014-2015(2021) RYNGELBLUM, Marcelo; PERES, Maria Fernanda TourinhoDeadly 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 Sao 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 Sao 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.
