Violence and post-traumatic stress disorder in Sao Paulo and Rio de Janeiro, Brazil: the protocol for an epidemiological and genetic survey

Background: violence is a public health major concern, and it is associated with post-traumatic stress disorder and other psychiatric outcomes. Brazil is one of the most violent countries in the world, and has an extreme social inequality. Research on the association between violence and mental health may support public health policy and thus reduce the burden of disease attributable to violence. the main objectives of this project were: to study the association between violence and mental disorders in the Brazilian population; to estimate the prevalence rates of exposure to violence, post-traumatic stress disorder, common metal disorder, and alcohol hazardous use and dependence: and to identify contextual and individual factors, including genetic factors, associated with the outcomes.Methods/design: one phase cross-sectional survey carried out in São Paulo and Rio de Janeiro, Brazil. A multistage probability to size sampling scheme was performed in order to select the participants (3000 and 1500 respectively). the cities were stratified according to homicide rates, and in São Paulo the three most violent strata were oversampled. the measurements included exposure to traumatic events, psychiatric diagnoses (CIDI 2.1), contextual (homicide rates and social indicators), and individual factors, such as demographics, social capital, resilience, help seeking behaviours. the interviews were carried between June/2007 February/2008, by a team of lay interviewers. the statistical analyses will be weight-adjusted in order to take account of the design effects. Standardization will be used in order to compare the results between the two centres. Whole genome association analysis will be performed on the 1 million SNP (single nucleotide polymorphism) arrays, and additional association analysis will be performed on additional phenotypes. the Ethical Committee of the Federal University of São Paulo approved the study, and participants who matched diagnostic criteria have been offered a referral to outpatient clinics at the Federal University of São Paulo and Federal University of Rio de Janeiro

The establishment of injury surveillance systems in Colombia, El Salvador, and Nicaragua (2000-2006) Establecimiento de sistemas de vigilancia de lesiones en Colombia, El Salvador y Nicaragua (2000-2006)

<abstract language="spa">La Organización Panamericana de la Salud (OPS), en colaboración con los Centros para el Control y la Prevención de Enfermedades (CDC) de los Estados Unidos de América, estableció en 2000 sistemas para la vigilancia de lesiones en Colombia, El Salvador y Nicaragua. Estos sistemas, basados en los servicios hospitalarios de emergencia, formaron parte de un proyecto piloto fundamentado en las guías para la vigilancia de lesiones, desarrolladas por la Organización Mundial de la Salud (OMS) y los CDC. Los objetivos de este proyecto eran evaluar la utilidad de las guías de la OMS/CDC, crear mecanismos apropiados para la vigilancia de lesiones en los tres países, promover intervenciones preventivas adecuadas e integrar la prevención y el control de lesiones en proyectos nacionales de salud pública. En este artículo se describe el proyecto piloto de la OPS/CDC y se resaltan los principios más importantes y las lecciones aprendidas durante sus seis años de funcionamiento (2000-2006). Entre las principales recomendaciones se encuentran la integración de la vigilancia de las lesiones en las unidades de epidemiología e información existentes en los ministerios de salud, la recogida de los datos importantes exclusivamente, la garantía de monitoreos y evaluaciones adecuados y la adopción de las prácticas que han demostrado ser más efectivas para el entrenamiento de personal y la diseminación de información
