Between 1980 and 2010 there were 1 million homicides in Brazil. Dramatic increases in homicide rates followed rises in inequality, more young men in the population, greater availability of firearms, and increased drug use. Nevertheless, disarmament legislation may have helped reduce homicide rates in recent years. Despite its very high rate of lethal violence, Brazil appears to have similar levels of general criminal victimization as several other Latin American and North American countries. Brazil has lower rates of drug use compared to other countries such as the United States, but the prevalence of youth drug use in Brazil has increased substantially in recent years. Since 1990, the growth of the Brazilian prison population has been enormous, resulting in the fourth largest prison population in the world. Through a systematic review of the literature, we identified 10 studies assessing the prevalence of self-reported offending in Brazil and 9 studies examining risk factors. Levels of self-reported offending seem quite high among school students in Brazil. Individual and family-level risk factors identified in Brazil are very similar to those found in high-income countries.
Aims Evaluate the effects of lowering the blood alcohol concentration (BAC) limit on road traffic fatalities and injuries in the State and capital of Sao Paulo, Brazil. Design Time series analysis using ARIMA modelling. Setting The augmented risk of road traffic accidents when under the influence of alcohol is well documented. However, many developing countries do not have a drink-driving law or have BAC limits that are above 0.05 g/dl. In Brazil, a new law introduced in 2008 has lowered the BAC limit for drivers from 0.06 to 0.02, but the effectiveness in reducing traffic accidents remains uncertain. Measurements and participants Data on injuries and deaths caused by road traffic accidents in both regions were collected from January 2001 to June 2010, comprising a total of 1,417,087 injuries and 51,561 fatalities. Findings The new traffic law was responsible for significant reductions in traffic injuries and fatalities rates in both localities (P<0.05). A stronger effect was observed for traffic fatalities (−7.2 and −16.0% in the average monthly rate in the State and capital, respectively) compared to traffic injuries rates (−1.8 and −2.3% in the State and capital, respectively). Conclusions Lowering BAC limits had a greater impact on traffic fatalities than injuries, with a higher effect in the capital where presumably the police enforcement was enhanced, and points to the relevance of these measures on the effectiveness of such law. Rigorous investigations on the effects of strategies derived from high-income countries to control alcohol-impaired driving should be promoted in developing countries.
The authors investigate geographical patterns of homicide in São Paulo, Brazil. The geography of crime in developing world cities has been an underresearched area in part because of the lack of good-quality, geocoded offence data. In the case of São Paulo the availability of a new digital police dataset has provided the opportunity to improve our understanding of its crime patterns. The authors report the testing of hypotheses about the spatial variation in homicide rates. This variation is explained by poverty, situational conditions determined by differences in land use, and processes that indicate links with the geography of drug markets and the availability of firearms.
The homicide rates in the city and state of São Paulo were cut in half in the years from 2001 to 2007. The decline in the city of São Paulo was especially striking and parallels the decline in New York City in the 1990s. It can be confirmed with a number of independent data sources and was significantly larger than in other Brazilian cities. The decline may be attributed to more effective policing methods including the better enforcement of strict gun-control legislation. It demonstrates that effective measures can be taken to reduce lethal crime in a developing country without waiting to solve underlying socioeconomic problems.
OBJETIVO: O aumento verificado nas taxas de homicídios aponta para a necessidade de melhorar a compreensão do problema. O objetivo do presente trabalho foi conhecer as informações adicionais acerca da mortalidade por homicídios provenientes de diferentes fontes de dados. MÉTODOS: Foram analisados os dados de homicídios entre residentes do Município de São Paulo, para o segundo semestre de 2001 obtidos nas declarações de óbito, laudos de necropsia e boletins de ocorrência policial. As informações foram analisadas sob a forma de números absolutos, proporções e coeficientes. Para a verificação de diferenças estatísticas foi utilizado o teste do qui-quadrado de Pearson. RESULTADOS: O coeficiente de homicídios foi 57,2/100.000, sendo que os valores mais altos foram encontrados entre os homens na faixa de 15 a 29 anos. O percentual do uso de armas de fogo foi 88,6%, mais alto entre homens que em mulheres. A localização anatômica de lesões mais freqüentes foi a cabeça (68,9%). Entre as vítimas que tiveram o exame toxicológico realizado, 42,5% tinham feito uso de álcool (44% para os homens e 24% nas mulheres). Há maior concentração de ocorrências nos finais de semana no horário noturno. Em 74,6% dos óbitos, as vítimas residiam próximas ou no mesmo local de ocorrência do evento. CONCLUSÕES: Os achados do estudo apontam que a integração de dados permite melhorar a qualidade da informação, contribuindo para a compreensão dos homicídios.
