[Suicide and medical practices: Assessing the way of life among Colombian coffee-growing rural men in mental health care]. / Suicidio y prácticas médicas: la valoración del modo de vida de hombres campesinos caficultores colombianos en la atención de la salud mental.

The aim was to understand the way of life and self-care practices in mental health among adult male farmers living in a municipality in the Risaralda department, located in the coffee axis of Colombia, marked by a high incidence of suicides. An ethnographic study was conducted between March and December 2021, employing a combination of methods including interviews, participant observation, document review, and field diaries. Economic and social aspects undergoing transformations were identified, impacting gender roles, family dynamics, and caregiving possibilities for these men. By observing how men discuss their suffering and the resources available to address it, it can be concluded that mental health practices function more as self-care resources, while health services often provide symptom-based care, neglecting attentive listening. These findings are valuable for shaping services and life care strategies that align with the conditions of rural men in Colombia.

El objetivo fue conocer el modo de vida y las prácticas de autocuidado en salud mental de los hombres adultos campesinos, que viven en un municipio del departamento de Risaralda en el eje cafetero de Colombia con alta incidencia de suicidios. Entre marzo y diciembre de 2021, se realizó un estudio etnográfico, haciendo uso de una combinación de métodos: entrevistas, observación participante, revisión documental y diario de campo. Se identificaron aspectos económicos y sociales cuyas transformaciones han afectado los roles de género, las dinámicas familiares y las posibilidades de cuidado para los hombres. Al observar cómo los hombres hablan de su sufrimiento y de los recursos con que cuentan para atenderlo, puede concluirse que las prácticas de salud mental se encuentran más bien como recursos de autoatención y los servicios de salud ofrecen atención basada en síntomas del cuerpo, de modo que abandonan la escucha. Estos hallazgos son útiles para pensar servicios y estrategias de cuidado de la vida que se adapten a las condiciones de hombres campesinos en Colombia.

One-year outcomes of two community-based mental health interventions for Afro-Colombian survivors of the armed conflict and displacement.

The objective of the study is to assess the middle-term effects (1 year after intervention) of two community-based mental health interventions, Common Elements Treatment Approach intervention, CETA, and Narrative Community Group Therapy intervention, NCGT, in two cities of the Colombian Pacific region (Buenaventura and Quibdó). A follow-up study was conducted on a cohort of trial participants. In this trial, the positive effects of two mental health interventions were evaluated; assessment was carried out in separate groups (CETA arm, NCGT arm and a control group) of the reduction of symptoms of anxiety, depression, post-traumatic stress and function impaired mentality. The participants were Afro-Colombian survivors of the armed conflict and displacement living in Buenaventura and Quibdó. They were surveyed using the same instrument used in the original trial. Intent-to-treat analyses were performed, and longitudinal mixed-effects regression models with random effects were used to analyse the middle-term effects of the interventions. At 1-year post-intervention, participants in Buenaventura who received the CETA intervention experienced a decrease in depression (-0.23; p = 0.02), post-traumatic stress symptoms (-0.23; p = 0.02) and total mental health symptoms (-0.14; p = 0.048). In Quibdó, the NCGT intervention significantly improved function impairment (-0.30; p = 0.005). CETA and NCGT interventions have the potential to maintain a reduction of mental health symptoms in participants from the Colombian Pacific region.

Mental health Narrative Community-Based Group Therapy in violence-displaced Afro-Colombians: a randomized controlled trial.

This study aims to evaluate the effect of a mental health Narrative Community-Based Group Therapy (NCGT) in Afro-Colombian violence survivors. A randomized controlled trial was conducted in Buenaventura and Quibdó, Colombia. Afro-Colombian adults (n=521) were randomly allocated to a NCGT (n1=175), a wait-control group (n2=171) or a Common Elements Treatment Approach (CETA, n3=175). The CETA was described separately given conceptual/methodological differences. Lay psychosocial community workers delivered the NCGT. Symptoms were assessed before and after intervention/wait with culturally adapted mental health symptoms and gender-specific functionality scales. Intent to treat analysis and mean difference of differences were used for comparisons. In Buenaventura, a significant reduction in functional impairment (mean difference: -0.30, 95% Confidence Interval [95% CI]: -0.55, -0.05) and depression (mean difference: -0.24, 95% CI: -0.42, -0.07) were found, with small and moderate effect size, respectively. In Quibdó, functionality improved significantly (mean difference: -0.29, 95% CI: -0.54, -0.04, small effect size). Even though differences in depression and anxiety were not significant, there were reductions in symptoms. The NCGT is effective in improving daily functioning among violence victims in the Colombian Pacific and has the potential to reduce symptoms of depression. Further exploration is required to understand the effects of a narrative group therapy for mental health in Afro-Colombian populations.Trial Registration: ClinicalTrials.gov number: NCT01856673 (https://clinicaltrials.gov/ct2/show/NCT01856673).

Seasonal and Temporal Patterns of Homicides and Suicides in Cali and Manizales, Colombia: A Times-Series Analysis 2008-2015.

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.

Performance of a Likert adaptation of the SRQ-20 scale among women victims of intimate partner violence in Colombia: an exploratory study.

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.

Exposición a violencia de género en una población de mujeres consultantes a un servicio de psiquiatría comunitaria en Cali, Colombia / Exposure to gender violence in a population of women consulting a Community Psychiatry service in Cali, Colombia

RESUMEN Objetivo Conocer las características sociales, sintomatología mental y exposiciones a hechos de violencia de mujeres consultantes a un servicio de salud mental comunitaria en una Institución de Atención Primaria. Metodología Se realizó un estudio de corte trasversal descriptivo en el programa de Psiquiatría Comunitaria de dos centros asistenciales de la Red de Salud de Ladera E. S. E. en Cali, Colombia. Se analizó el contenido de 157 registros del año 2018, usando estadística descriptiva para las variables sociodemográficas, clínicas y relacionadas con su historial psiquiátrico. Resultados El 43,59% del total de las mujeres consultó por trastornos afectivos, ninguna enunció situaciones relacionadas con violencia en el motivo de consulta. Sin embargo, cerca del 16% enunció situaciones de violencia en el apartado de "enfermedad actual", mientras que el 39,49% lo señaló como parte de los "antecedentes personales", y el 15,29% lo relacionó con los "antecedentes familiares". tras comparar este grupo de mujeres expuestas a violencia con las no expuestas, se encontró que los trastornos depresivos eran más frecuentes en el grupo expuesto (58,53%; p=0,035). El manejo farmacológico fue más frecuente en mujeres no expuestas y de tipo psicosocial en mujeres expuestas (p<0,05). Conclusiones Aunque se hubiese enunciado alguna forma de violencia dentro del contenido de las historias clínicas, menos del 2% de los reportes incluyó diagnósticos relacionados con violencia de género.

ABSTRACT Objective This study aims to know the social characteristics, mental health symptoms, and exposure of violence of women who are patients of the community psychiatry service in a Primary Care Institution. Methodology An observational and descriptive study was conducted. Patients were women who have been treated in the Community Mental Health Program in two healthcare centers of the Ladera Health Network: E.S.E in Cali, Colombia. 157 records from 2018 was analyzed using descriptive statistics for sociodemographic and clinical variables and those related to their psychiatric history. Results 43.59% of all women consulted for affective disorders. None reported any situation related to violence as the reason for consultation. However, violent situations were enunciated by 15.92% of the women in the "current illness" box, while 39.49% pointed it out as part of "personal history," and 15.29% related it to the "family history". Comparing this group of women exposed to violence with those not exposed, it was found that depressive disorders were more frequent in the exposed group (58.53%; p=0.035). Pharmacological management was more frequent in unexposed women and psychosocial in exposed women (p<0.05). Conclusions Although some form of violence had been stated within the medical record content, less than 2% of the reports included diagnoses related to gender violence.

Performance of the Paediatric Trauma Score on survival prediction of injured children at a major trauma centre: A retrospective Colombian cohort, 2011-2019.

Background: Despite improvements in children's health due to a reduction in infections, trauma continues to cause many deaths among adolescents. Strategies to mitigate morbidity and mortality from trauma include severity scores to classify and refer patients to the appropriate hospitals to provide better management; however, these strategies have not been assessed in Colombian children. This study aimed to describe the characteristics and outcomes of injured children and evaluate the performance of the Pediatric Trauma Score (PTS) in predicting survival at a major trauma centre in a Colombian city. Methods: This was a retrospective cohort study of children aged <18 years who were treated for injuries at a hospital in Colombia. The primary outcome was 30-day mortality. A simple logistic regression model was used with PTS as the predictor variable and vital status at discharge as the outcome variable. PTS performance was assessed by discrimination using the area under the receiver-operating characteristic (AUROC) curve and by calibration using the Hosmer-Lemeshow (HL) goodness-of-fit test. Findings: A total of 1047 children were admitted. The median age was 12 years (interquartile range [IQR]=5-15); 73·7% were male, and 66·1% had blunt trauma. The most frequent cause of injury was traffic accident (31·5%) followed by assaults (29%). Mortality was 5·9%; 61·3% of these deaths occurred in adolescents between 15 and 17 years of age and 71% of deaths in this age group were due to injuries from a firearm. The PTS had a median of 7 (IQR=5-9), an AUROC of 0·93, and good calibration (HL=7·97, p = 0·33). Interpretation: The highest proportion of trauma and death occurred among adolescents. Interpersonal violence was the most frequent cause of death in this age group. The PTS showed good predictive power for survival, with excellent discrimination and good calibration. Funding: None.

A qualitative study on factors associated with intimate partner violence in Colombia.

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.

Impacts of violence on the mental health of Afro-descendant survivors in Colombia.

The Colombian armed conflict has disproportionately affected minorities, especially afro-Colombian communities. However, there is a lack of evidence about mental health of victims. This study aims to describe the prevalence of mental illness and its associated factors in Afro-descendant violence survivors in Buenaventura and Quibdó, Colombia. A cross-sectional study was carried out using data from a previous trial which aimed to reduce mental health symptoms (ClinicalTrials.gov: NCT01856673). Data of 710 adults identified through a snowball sampling technique was analysed. Diagnoses of depression, anxiety, post-traumatic stress disorder (PTSD), and dysfunction were established using adapted versions of the Hopkins Symptoms Checklist and the Harvard Trauma Questionnaire, plus variables identified in a qualitative study. Multivariate regressions were used to identify associated factors with these diagnoses. The prevalence of depression, anxiety and PTSD in both cities was 26.62% (95% confidence interval [95%CI]: 20.30;23.89), 36.53% (95%CI: 30.63;42.36), and 39.15% (95%CI: 33.36;44.83), respectively. Being married and having registered with the government as victim of the conflict were found to be protective factors for depression and PTSD, respectively. Psychological trauma, unemployment, and traumatic experiences, amongst others, were found as risk factors. The Colombian armed conflict, plus disparities and social exclusion, may be associated with mental health morbidity.

Inequities in diagnosis of Fragile X syndrome in Colombia.

BACKGROUND: Fragile X syndrome (FXS) is the most common cause of inherited intellectual disability and autism spectrum disorder (ASD). In Colombia, there are no screening or testing protocols established for the diagnosis of FXS. In this study, we aimed to describe the diagnostic trends of FXS in Colombia. METHODS: Data were included on 1322 individuals obtained based on data from the only 2 databases available. Sociodemographic information and data related to the diagnostic process were obtained and included in this study. RESULTS: The average age at the time of diagnosis for individuals with the full mutation (FM) was of 26.9 ± 2.57 years and was strongly dependent on sex and socioeconomic status. Most individuals with a molecular diagnosis were from the main cities. CONCLUSION: The overall age of diagnosis of FXS is later in life than reports from other countries. Restricted access to molecular testing through the national health system might explain this discrepancy in Colombia.

Análisis espacio-temporal del SARS-COV-2 en Cali, Colombia / SARS-coV-2 spatio - temporal analysis in Cali, Colombia

RESUMEN Objetivo Describir la distribución espacio-temporal del COVID-19 en la ciudad de Cali durante el primer mes de epidemia. Métodos Se realizó un análisis exploratorio de datos espaciales, compuesto por un análisis de densidad de Kernel y se verificó la presencia de patrones espaciales por medio de la función K de Ripley. Resultados La distribución espacial de los casos tiende a concentrarse inicialmente en el norte y sur de la ciudad, con una dinámica cambiante hacia el oriente y occidente. Conclusiones El patrón espacial identificado puede estar influenciado por las medidas de aislamiento tomadas a nivel local y nivel nacional, además no se puede descartar el efecto del poco acceso que tiene la población general a las pruebas diagnósticas, los retrasos y represamientos para conocer los resultados de las mismas y aun los posibles sesgos por dificultades en la técnica de toma de la muestra o su conservación.(AU)

ABSTRACT Objective To describe the spatio-temporal distribution of the COVID-19 in the city of Cali during the first month of the epidemic. Methods An exploratory analysis of spatial data was carried out, consisting of a kernel density analysis and the presence of spatial patterns was verified by the K-Ripley function. Results The spatial distribution of the cases tends to initially concentrate in the north and south of the city, with a changing dynamic towards the east and west. Conclusions The identified spatial pattern may be influenced by the isolation measures taken at the local and national level, but the effect of the low access of the general population to diagnostic tests, delays and restraints to know the results cannot be ruled out and even possible biases due to difficulties in the technique of taking the sample or its conservation.(AU)

Cultural adaptation and validation of the Geriatric Oral Health Assessment Index - GOHAI - Colombian version.

OBJECTIVE: This study aims to carry out the cultural adaptation and the validation of the GOHAI scale for the Colombian population. METHODS: Translation process, cultural adaptation, and content and face validity were carried out with a sample of 63 participants as a pretest. The validation counted with a sample of 7,200 subjects, divided into two groups: a work sample (WS) with 3,628 subjects and a confirmatory sample (CS) with 3,572 subjects. Construct, criterion validity and internal consistency were performed for both samples. Test-retest reliability was assessed with a sub-sample of 75 participants. RESULTS: The GOHAI showed an appropriate face and content validity, the pre-test revealed an understandable questionnaire, the scale showed a unidimensional factorial structure and a Cronbach's Alpha of 0.8. Convergent validity with a self-perception on general health scale pointed to a significant correlation (p= 0.0001), while discriminant validity showed significant differences regarding groups according to age group, skin color, educational level, socio-economic level, healthcare affiliation and self-perception about need of dental prostheses. Gender groups did not show significant differences among groups within either sample. The CS showed similar results, differences existed among factorial structures of 2 and 3 factors, and for discriminant validity, the CS showed statistically significant differences for the Area variable not in the WS. Kendall's test-retest analysis's correlation is 0.85 (p= 0.0000). CONCLUSIONS: The GOHAI scale is valid and reliable enough to be used as a measure of Oral-Health-Related Quality of Life in the Colombian elderly population, also could be applied for other Latin-American populations.

Impact evaluation of camera enforcement for traffic violations in Cali, Colombia, 2008-2014.

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.
