          Abstract

          Resumo Analisou-se a evolução de taxas das categorias homicídio doloso, latrocínio, lesão corporal seguida de morte, homicídio por auto de resistência, policial morto, pessoa desaparecida e encontro de cadáver, no Estado e na cidade do Rio de Janeiro e na Área Integrada de Segurança Pública 16 (AISP 16). Para tanto, foi realizado estudo ecológico, no período de 2002 a 2013, utilizando os dados do Instituto de Segurança Pública. Para análise da evolução temporal e tendência das taxas de homicídio doloso, de autos de resistência e de pessoas desaparecidas foi realizada regressão Joinpoint, considerando como variável dependente as referidas taxas e como variável independente o ano calendário. Para as demais categorias analisou-se apenas a evolução temporal das taxas a partir do cálculo da variação relativa destas no início e no final do período. Houve queda de taxas em todas as categorias, com exceção de pessoas desaparecidas. A taxa de homicídio doloso apresentou tendência significativa de decréscimo nas três localidades. Os resultados contribuíram para descrever o padrão da violência nas três localidades a partir do diálogo entre as ciências sociais, saúde e segurança pública, o que permitiu contemplar aspectos subjetivos e objetivos ligados aos achados do estudo.

          Abstract The evolution of rates were analyzed for the following categories: murder, larceny, bodily harm followed by death, homicide for resistance to police resulting in death, policeman killed, missing persons and dead bodies found in the state and city of Rio de Janeiro and in Integrated Public Security Area 16 (AISP 16). An ecological study was conducted for the period from 2002 to 2013, using data from the Public Security Institute. To analyze the time trend and evolution of murder charges, resistance to police resulting in death and missing persons rates, Joinpoint regression was performed, using these rates as the dependent variables and the calendar year as the independent variable. For the other categories only the time trends of the rates were analyzed for the relative change in rates at the beginning and end of the period. There were falls in rates in all categories, except for missing persons. The murder rate showed a significant downward trend in the three locations. The results contributed to definition of the pattern of violence in the three locations based on the dialogue between the social sciences, public health and safety that made it possible to establish subjective and objective aspects linked to the study findings.

          Permutation tests for joinpoint regression with applications to cancer rates.

          The identification of changes in the recent trend is an important issue in the analysis of cancer mortality and incidence data. We apply a joinpoint regression model to describe such continuous changes and use the grid-search method to fit the regression function with unknown joinpoints assuming constant variance and uncorrelated errors. We find the number of significant joinpoints by performing several permutation tests, each of which has a correct significance level asymptotically. Each p-value is found using Monte Carlo methods, and the overall asymptotic significance level is maintained through a Bonferroni correction. These tests are extended to the situation with non-constant variance to handle rates with Poisson variation and possibly autocorrelated errors. The performance of these tests are studied via simulations and the tests are applied to U.S. prostate cancer incidence and mortality rates. Copyright 2000 John Wiley & Sons, Ltd.
