RESUMO

BACKGROUND: Violence is an important public health problem and one of the main causes of deaths worldwide. The mental health consequences of surviving intimate partner violence (IPV) include depression, anxiety and post-traumatic stress disorder. Previous studies have identified that there is a relationship between depression and level of disability in female survivors of IPV. Estimating the direct, indirect or total effect of an exposure on an outcome makes it possible to identify mediating effects between a group of variables. Detecting mediation effects is useful for identifying casual pathways that generate a final outcome and provides a rationale for designing interventions to target the mediator, which in turn positively affects the outcome. The objective was to identify the mediating role of depressive symptoms on the relationship between IPV and disability. METHODS: This was a cross-sectional study of 94 women over the age of 18 who were survivors of IPV by men. They were recruited from two public hospitals in Cali and Tuluá in southwest Colombia. An analysis of casual relationships was performed using structural equation modelling that was made up of: four exogenous observed variables (age, current relationship status [in a relationship or single], level of schooling, and history of an impairment), intermediate endogenous variables (violence and depressive symptoms), and the main endogenous variable (disability). The analyses were carried out in Stata14.2. RESULTS: The direct effect of IPV severity on the level of disability was not statistically significant (ß=0.09; P=0.63). However, the indirect effect of IPV severity on disability mediated by depressive symptoms was (ß=0.39; P<0.01). The total effect of IPV severity on the level of disability was even greater (ß=0.48; P=0.01). CONCLUSIONS: This study found a complete mediating role of depressive symptoms on the relationship between the severity of IPV and the level of disability for the female participants in this study. The results of this research contribute to defining strategies to prevent and address intimate partner violence, depressive symptoms and disability in this population.

RESUMO

OBJECTIVE: To identify seasonal and temporal variations in daily incidence of homicides and suicides in Cali and Manizales, Colombia during 2008-2015. MATERIALS AND METHODS: An ecological time series study was performed using negative binomial regression models for daily incidence of homicides and suicides; analyses were controlled for yearly trends and temporal autocorrelations. RESULTS: Saturdays, Sundays, December holidays as well as New Year and New Year's Eve were associated with an increased risk of homicides in both cities. Suicide risk increased during December holidays and New Year in both cities. In addition, the suicide risk increased on paydays, Saturdays, Sundays, and Mondays in Cali, and it decreased during the Holy Week holidays in Manizales. December patterns of suicides and homicides are the opposite in each city, and between cities. CONCLUSIONS: The incidences of homicides and suicides are not homogeneous over time. These patterns can be explained partially by alcohol consumption and changes in people's routine activities which may modify exposure to violent circumstances.

RESUMO

Women who are victims of intimate partner violence often suffer of depression and anxiety disorders. We evaluated the performance of the SRQ-20 scale (screening test for common mental health disorders), in women victims of intimate partner violence by male partners. A total of 100 women were surveyed from the out-patient mental health services in four health institutions in Valle del Cauca (Colombia). SRQ-20 scales (Binary version versus Likert version) were compared with mental health diagnoses based on the HSCL-25 scale, as the gold standard. Optimal SRQ-20 cut-off score is > = 6 points; lower than the initially suggested, sensitivity of 96.6% and specificity of 90.9%. The new SRQ-20-Likert scale, establishing a cut-off of > = 8 points, shows better sensitivity (98.9%) and equal specificity than the original scale. Studied SRQ-20 scales are promising instruments for screening mental health disorders among women victims of intimate partner violence in primary health care settings.

RESUMO

Intimate partner violence (IPV) is a human rights violation and a serious global public health problem. This study investigated factors associated with IPV in female survivors in Colombia. Four focus group discussions with female survivors of IPV and 15 key informant interviews with professionals from psychological, social and legal services and community leaders were conducted in Cali and Tuluá. Participant recruitment was via purposive sampling. Transcripts were analysed manually taking a social constructivist standpoint and a content analysis approach. Factors associated with IPV were divided into four themes: cultural beliefs, jealousy, alcohol abuse, and personal history of IPV. The first theme was divided into: patriarchy, gender roles, normalisation of violence, and unawareness of rights, economic dependence, and 'men own women'. The sub-themes were all inter-related and underpinned by patriarchal values. IPV was described as a sociocultural construction formed by patriarchal values ingrained in community and societal norms and individual processes. Therefore, academia, governmental and non-governmental bodies and society are urged to together, create preventative, context specific strategies for individuals, communities and societies.

Resumo A violência por parceiro íntimo (VPI) é uma violação dos direitos humanos e um grave problema de saúde pública global. Este estudo investigou fatores associados à VPI em mulheres sobreviventes na Colômbia. Quatro discussões de grupos focais com mulheres sobreviventes de VPI e 15 entrevistas com informantes-chave com profissionais de serviços sócio-médico-legais foram realizadas usando amostragem intencional nas cidades de Cali e Tuluá. As transcrições foram analisadas manualmente, sob um ponto de vista construtivista social e uma abordagem de análise de conteúdo. Os fatores associados à VPI foram divididos em 4 temas: crenças culturais, ciúmes, abuso de álcool e história pessoal da VPI. O primeiro tema foi dividido em: patriarcado, papéis de gênero, normalização da violência, desconhecimento de direitos, dependência econômica e 'homens possuem mulheres'. VPI foi descrita como uma construção sociocultural formada por valores patriarcais e processos individuais. A VPI é causada por uma complexa interação de diferentes fatores nos níveis do indivíduo, relacionamentos, comunidade e social. Os órgãos governamentais e não governamentais e a sociedade são instados a criar juntos estratégias preventivas e específicas no contexto.

RESUMO

Abstract Cali is one of the cities in Colombia and Latin America with the highest rate of homicides, with around one third of homicides being attributed to street gang-related violence. In 2016, the Mayor's office from Santiago the Cali - Colombia, the Police Department and the Cisalva institute from Universidad del Valle worked together to develop an holistic intervention, "TIP -Youth without frontiers", to reduce street gang-related violence in Cali's communes. The intervention comprised six components focusing on developing personal/emotional skills, improving access to health and other public services, reducing substance use, connecting youth with employment and educational opportunities, promoting participation in sports and recreational activities, and improving the restitution of citizen rights to street gang members. This study aimed to describe the characteristics and implementation of this transformative street gang program and to describe changes in street gang-related homicides that could be associated with the implementation of this program. The program started contacting street gangs in January 2016, recruiting the first street gang members in August 2016. As of December 2018, 2.107 youth (from 84 Police identified street gangs) have participated in the program. A reduction in street gang-related homicides was observed in Cali's communes from 2015 to 2018. In intervened communes these homicides decreased on average by 80%, suggesting that the program could have contributed to the reduction of street gang-related violent behavior in these areas.

Resumen Cali es una de las ciudades de Colombia y de Latinoamérica con la tasa de homicidios más alta, con alrededor de un tercio de los homicidios atribuidos a la violencia entre pandillas. En 2016, la Alcaldía de Santiago de Cali - Colombia, la Policía Nacional y el Instituto Cisalva de la Universidad del Valle trabajaron juntos para desarrollar una intervención holística, "TIP - Jóvenes sin fronteras", con el fin de reducir la violencia relacionada con las pandillas en las comunas de Cali. La intervención abarcó seis componentes centrados en desarrollar habilidades personales/emocionales, mejorar el acceso a los servicios de salud y otros servicios públicos, reducir el consumo de sustancias, conectar a los jóvenes con oportunidades laborales y educativas, fomentar la participación en actividades deportivas y recreativas, y restituir los derechos cívicos a integrantes de las pandillas. El objetivo de este estudio era describir las características y la implementación de este programa de transformación de pandillas, y describir los cambios en la tasa de homicidios relacionados con pandillas que podrían estar asociados con la implementación de este programa. El programa comenzó contactando a las pandillas en enero del 2016, reclutando a los primeros miembros de estas en agosto del 2016. A diciembre del 2018, 2.107 jóvenes (de 84 pandillas identificadas por la policía) han participado en el programa. Se observó una reducción de los homicidios relacionados con pandillas en las comunas de Cali entre 2015 y 2018. En las comunas intervenidas, estos homicidios disminuyeron en promedio un 80%, lo que sugiere que el programa podría haber contribuido a la reducción del comportamiento violento relacionado con las pandillas en estas áreas.

RESUMO

INTRODUCTION: Cameras for detecting traffic violations have been used as a measure to improve road safety in different countries around the world. In Cali, Colombia, fixed cameras were installed in March 2012 on a number of roads and intersections. All camera devices are capable of detecting simultaneously the following traffic violations: driving over the speed limit, running a red light or stop sign, violation of the traffic ban schedule, and blocking the pedestrian crosswalk. OBJECTIVE: To evaluate the impact of camera enforcement of traffic violations in Cali, Colombia. METHODS: A quasi-experimental difference-in-differences study with before and after measurements and a comparison group was conducted. We observed 38 intervention areas and 50 comparison areas (250 m radius), during 42 months before and 34 months after the installation of cameras. Effects were estimated with mixed negative binomial regression models. RESULTS: In intervention areas, after 12 months, there was a reduction of 19.2% of all crashes and a 24.7% reduction of injury and fatal crashes. In comparison areas, this reduction was 15.0% for all crashes and 20.1% for injury and fatal crashes. After adjusted comparisons, intervention sites outperformed comparison sites with an additional yearly reduction of 5.3% (p = 0.045) for all crashes. CONCLUSIONS: The use of cameras for detecting traffic violations seems to have a positive effect on the reduction of crashes in intervention areas. A beneficial spillover effect was found as well in comparison areas; but more evaluations are needed.

RESUMO

Given the context and the number of armed conflict victims in the Colombian Pacific coast and their difficulties to access psycho-social care, Narrative Community-based Group Therapy appears as a viable mental health intervention. The objective of this study is to describe the process of implementation and results of the intervention in Afro-Colombian victims of violence, in the municipalities of Buenaventura and Quibdó. More specifically, we will be looking at the perspectives of workers and supervisors, through evaluative case studies and individual in-depth interviews. The therapy allows us to identify support and coping systems through coexistence, communication and interaction. It requires an adaptation process to the diversity of knowledge and expressions of victims of Colombian violence, greater empathy from care providers and rigor in their profiles selection, facilities ensuring security and confidentiality, and links with other educational, employment and recreational organizations. It is important to include these results while improving current and future intervention processes.
