"Give Me Proof": A Covert but Coercive Form of Non-partner Sexual Violence Contributing to Teen Pregnancy in Haiti and Opportunities for Biopsychosocial Intervention.

Adolescent girls in low-resource settings account for over 7.3 million births annually (generally unplanned). Unplanned teen pregnancies are increasing in low-resource settings. As part of a funded Round 20 Grand Challenges Exploration project (Healthy Minds for Adolescent Mothers), we investigated unplanned teen pregnancies in Haiti's Cité Soleil shantytown, teens' biopsychosocial challenges, and desirable interventions. Key stakeholders (N = 23): pregnant teens (13-17-year-olds, n = 8; 18-19-year-olds, n = 8) and health providers (18 or older, n = 7), participated by age group and role in focus groups (FGs). ATLAS.ti facilitated the analysis of transcribed FG audio recordings. Ninety-four percent (n = 15) of teens reported "Banm prèv," translated "Give me proof," as a cause of their unplanned pregnancies. Banm prèv describes when teens are propositioned by men who demand proof of their unpretentiousness or virginity. A subtle, covert, locally unchallenged phenomenon that is supported by damaging gender norms, Banm prèv constitutes an illusionary choice between teens' yielding non-consensual control of their bodies and the tacit alternative of gang rape. Banm prèv underscores teens' difficulty discerning consensual from coerced sex. Associated unplanned pregnancies occasion guilt, shame, stigma, depression, anxiety, and trauma in teens. Cité Soleil teens need contextually relevant, community-supported, age-appropriate interventions that challenge existing norms, build on cultural strengths, and include comprehensive sexuality education, including knowledge of reproductive rights. A traditional, contextually familiar, engaging, and humorous story-telling tradition, i.e., krik-krak, packaged in video format, is a useful framework for interventions to reduce depressive symptoms, stress, and anxiety for Cité Soleil teens experiencing unplanned pregnancies.

Comparing Prevalence and Correlates of Intimate Partner Sexual Victimization Relative to Other Victim-Offender Relationships in College Students.

Research on sexual victimization (SV) in college women often focuses on perpetration by nonpartners thus, little is known about SV by intimate partners on college campuses. To address this gap in the literature, the current study compared prevalence and revictimization rates and negative correlates of SV based on victim-offender relationship. Findings suggest higher prevalence rates of SV perpetrated by a nonpartner compared to an intimate partner although similar and alarming rates of revictimization. Regarding negative correlates of SV, no differences were identified based on victim-offender relationship; however, victims of SV by both an intimate partner and a nonpartner demonstrated the highest negative correlates. These findings demonstrate the importance of addressing SV by nonpartners and intimate partners and the necessity for tertiary prevention efforts to decrease revictimization.

Perceived discrimination is a potential contributing factor to substance use and mental health problems among primary care patients in Chile.

OBJECTIVES: Perceived discrimination is a prevalent problem that has been linked to negative health outcomes for victims. The goal of this research was to examine whether perceived discrimination within the past 6 months was related to 6-month prevalence of problem drinking, illicit drug use, major depressive disorder (MDD), and posttraumatic stress disorder (PTSD) in a sample of primary care patients in Chile. METHODS: Structured diagnostic assessments were administered to assess for MDD and PTSD using the Composite International Diagnostic Interview. The Alcohol Use Disorders Identification Test assessed hazardous alcohol use. Additional measures captured illegal drug use and discrimination in the past 6 months. Measures were administered to 2839 participants between the ages of 15 to 98 in primary care centers in the Chilean cities of Concepcion and Talcahuano. RESULTS: Controlling for demographic variables and previous trauma victimization, patients who reported discrimination in the past 6 months were significantly more likely to engage in hazardous alcohol use, illegal drug use, be diagnosed with MDD, and PTSD within this same time period than patients not reporting discrimination. CONCLUSIONS: This study highlights the importance of considering discrimination as a potential contributing factor to substance use and mental health problems in a Latin American sample.

Estudio epidemiológico de sucesos traumáticos, trastorno de estrés post-traumático y otros trastornos psiquiátricos en una muestra representativa de Chile / Epidemiology of trauma, PTSD and other psychiatric disorders in a representative population of Chile

In the last decade, our understanding of posttraumatic stress disorder (PTSD) has progressed from studies of war veterans and specific disaster victims to studies that examine the epidemiology of PTSD in the United States (USA) population. Epidemiologic data on PTSD in developing countries is an understudied area with the majority of studies were developed in the USA and other developed countries. Of the few epidemiological surveys undertaken in other countries, most of them have focused its interest on the prevalence rates of PTSD and its risk factors for following specific traumatic events. Besides increasing the international normative and descriptive data base on PTSD, an examination of prevalence rates and risk factors for PTSD in a socio-political and cultural context (that is markedly different to established market economies) can deepen our understanding of the phenomenology and determinants of PTSD. Although many psychiatric diagnoses can be related with previous traumatic experiences, PTSD has been identified as a disorder that requires a previous traumatic exposure for its diagnosis. A growing literature strongly suggests that early exposure to traumatic events disrupts crucial normal stages of childhood development and predisposes children to subsequent psychiatric sequelae. A series of epidemiological studies has demonstrated that childhood sexual abuse is associated with a range of psychiatric disorders in adulthood that includes mood, anxiety, and substance use disorders, even after adjusting for possible confounds, such as family factors and parental psychopathological disorders or other childhood adversities. There is little evidence of diagnostic specificity of childhood sexual abuse, although a consistent finding has been that alcohol and drug disorders are more strongly related to childhood sexual abuse than other psychiatric disorders. Other forms of childhood traumas have been less well studied. This article reviews the findings of an epidemiological study that took place in Chile and examined prevalence rates of PTSD, traumatic events most often associated with PTSD, comorbidity of PTSD with other lifetime psychiatric disorders, gender differences in PTSD as well as trauma exposure in a representative sample of Chileans. This article also reported a comparison of prevalence rates of various psychiatric disorders among persons who reported the first trauma during their childhood, those who reported the first trauma during their adulthood, and those with no trauma history. The study was based on a household-stratified sample of people defined by the health service system to be adults (aged 15 years and older). The study was designed to represent the population of Chile. This analysis is limited to three geographically distinct provinces, chosen as being representative of the distribution of much of the population. The interviews were administered to a representative sample of 2390 persons aged 15 to over 64 years. The measures used were the DSM-III-R PTSD and antisocial personality disorder modules from the Diagnostic Interview Schedule and modules for a range of DSM-III-R diagnoses from the Composite International Diagnostic. Traumatic events were categorized into one of 11 categories: military combat, rape, physical assault, seeing someone hurt or killed, disaster, threat, narrow escape, sudden injury/ accident, news of a sudden death or accident, other event (e.g. kidnapping, torture), or other experience. The translation into Spanish was conducted using the protocol outlined by the World Health Organization. The interviewers were all university students in their senior year studying social sciences. Taylor series linearization method was used to estimate the standard errors due to the sample design and the need for weighting. The analysis was conducted using procedures without replacement for non-respondents. The region, province, comuna, and district selected were used as the defined strata. Logistic regression with the corresponding 95% confidence interval was used to examine associations among PTSD, demographic risk factors, and trauma type. To examine whether the association between PTSD and gender could be explained by other risk factors, multivariate logistic regression analyses were also conducted. The first analysis found that the lifetime prevalence of PTSD was 4.4% (2.5% for men and 6.2% for women). Among the traumatic events, rape was most strongly associated with PTSD diagnosis. Among those exposed to traumas, women were significantly more likely to develop PTSD than men, after controlling for assaultive violence. The second analysis revealed that exposure to a lifetime trauma was associated with a higher probability of psychiatric morbidity in comparison with no trauma exposure. Traumas with childhood onset were significantly related to lifetime panic disorder, independent of number of lifetime traumas and demographic differences. This revealed that women had more probabilities than men of developing PTSD once they are exposed to trauma, independent of previous traumas, experiences of sexual assault, other violent experiences or level of education. Some authors have proposed that women have a higher vulnerability than men to develop PTSD and that there are sex differences in brain morphology, in the social interpretation of trauma, or/and in the peritraumatic dissociative experience. Although many theories have been proposed to explain this gender difference in PTSD, more research is needed to evaluate them empirically. This study highlights the importance of investigating the prevalence of PTSD, the patterns of comorbidity of PTSD, as well as gender differences of PTSD in non-English speaking countries. Although Chile has a different historical and socio-cultural context with respect to other countries in which the epidemiology of PTSD has been examined, in general, this study achieved similar results as those found in other studies. The results showed that PTSD is not an uncommon psychiatric illness, it is associated with a high degree of psychiatric comorbidity, it is more likely to predate other psychiatric disorders. Also, the results showed that men are more likely to be exposed to traumas than women, women are more likely than men to develop PTSD, and that PTSD is associated with relatively high treatment utilization. However, compared to another country in Latin America, such as Mexico, Chile has a lower prevalence of PTSD and trauma exposure, which may due to socio-economic factors, such as less inequity between the wealthy and the poor and less violence, crime, and poverty in Chile than Mexico. These studies also suggest that traumatic events that occur in childhood are related to specific disorders rather than those that occurred later in life. Individuals with childhood interpersonal trauma exposure are more likely to suffer from lifetime panic disorder, agoraphobia or PTSD compared to those who experience interpersonal trauma as an adult. However, research should examine the specificity of these disorders in relation to various types of childhood traumas. Limitations of the current study include the use of lay interviewers who, despite acceptable levels of reliability and validity, may be less accurate than clinicians as interviewers. Also the retrospective recall of lifetime disorders is likely to be less accurate than a more recent time frame. The sample used in this study does not show nation wide perspective, because the Southern portion of the country which includes much of the indigenous population was excluded. This study, like most epidemiological studies, did not use an-depth or validated index of trauma, which may have diluted findings. Since this study was cross-sectional, a direct cause-effect relationship cannot be assumed between trauma exposure and subsequent disorders.

Durante la década de 1990 en los Estados Unidos (EU), el conocimiento sobre el trastorno de estrés post-traumático (TEPT) evolucionó de estudios específicos en un principio, sobre veteranos de guerra y sobre víctimas de desastres, a estudios epidemiológicos más tarde, sin embargo, la epidemiología del TEPT en países en desarrollo ha sido un área poco estudiada hasta ahora. Los expertos en el área de trauma han propuesto que los sucesos traumáticos que ocurren en la niñez son más perjudiciales para la salud mental que aquellos que ocurren más tarde en la vida. Este trabajo revisa los resultados de un estudio epidemiológico llevado a cabo en Chile. Específicamente, se revisan los resultados sobre las tasas de prevalencia del TEPT, traumas asociados más frecuentemente con él, así como la comorbilidad de este trastorno con otros trastornos psiquiátricos a lo largo de la vida. Igualmente se analizaron las diferencias del TEPT en cada sexo, así como la exposición a traumas en una muestra representativa de chilenos. Además se comparó la prevalencia de trastornos psiquiátricos en personas que sufrieron su primer trauma durante la niñez, durante la edad adulta, o que no reportaron traumas durante su vida. En estos estudios epidemiológicos se usaron módulos del TEPT y trastorno de personalidad antisocial (TPA) de la entrevista diagnóstica siguiendo los criterios del DSM-III-R (DIS-III-R). Para evaluar el resto de los trastornos psiquiátricos se usó la Entrevista Diagnóstica Internacional Compuesta (CIDI). Estos instrumentos fueron administrados en tres ciudades chilenas a 2390 personas mayores de 15 años. Para estimar los errores estándares (EE) debido al diseño de la muestra y a la necesidad de ajuste se usó el método Taylor de linearización seriada. También se usó un análisis de regresión logística para examinar la relación entre el TEPT, los factores demográficos de riesgo y el tipo de trauma. Además se utilizó la regresión logística multivariada para evaluar si la relación entre el TEPT y el sexo pudiera ser explicada por medio de otros factores de riesgo, así como para calcular las tasas y la oportunidad relativa (razón de productos cruzados) de trastornos psiquiátricos a lo largo de la vida. El primer análisis arrojó que la prevalencia de TEPT a lo largo de la vida fue de 4.4% (2.5% para hombres y 6.2% para mujeres). De los hechos traumáticos reportados, la violación sexual tuvo una correlación más alta con el TEPT que los demás hechos traumáticos. Las mujeres tuvieron más probabilidades de experimentar TEPT que los hombres, después de controlar la variable asalto violento. El segundo análisis evidenció que los que habían sufrido traumas a lo largo de la vida tuvieron mayor probabilidad de tener un trastorno psiquiátrico en comparación con aquellos que no reportaron traumas. También se encontró que los que sufrieron su primer trauma durante la infancia tuvieron más probabilidad de desarrollar trastornos de pánico a lo largo de la vida que aquellos que sufrieron su primer trauma en la edad adulta, independientemente del número de traumas que sufrieron y de las diferencias demográficas. Aunque Chile tiene un contexto histórico-cultural y una economía diferente a otros países en los que se ha estudiado anteriormente la epidemiología del TEPT, el presente estudio reflejó tendencias similares a las reportadas en estudios previos. Los hallazgos expuestos enfatizan la importancia de investigar la prevalencia del TEPT, los patrones de comorbilidad del TEPT y las diferencias de sexo en la prevalencia del TEPT en diferentes países. También estos resultados sugieren que los sucesos traumáticos en la infancia (y no en la adultez) pueden estar relacionados con la ocurrencia de trastornos psiquiátricos específicos.

Epidemiology of trauma, post-traumatic stress disorder (PTSD) and co-morbid disorders in Chile.

BACKGROUND: In this study we examined the prevalence rates of post-traumatic stress disorder (PTSD), types of trauma most often associated with PTSD, the co-morbidity of PTSD with other lifetime psychiatric disorders, which disorders preceded PTSD, and gender differences in PTSD and trauma exposure in a representative sample of Chileans. METHOD: The DSM-III-R PTSD and antisocial personality disorder modules from the Diagnostic Interview Schedule (DIS) and modules for a range of DSM-III-R diagnoses from the Composite International Diagnostic Interview (CIDI) were administered to a representative sample of 2390 persons aged 15 to over 64 years in three cities in Chile. RESULTS: The lifetime prevalence of PTSD was 4.4% (2.5% for men and 6.2% for women). Among persons exposed to trauma, rape was most strongly associated with PTSD. Onset of PTSD significantly increased the risk of developing each of the 10 other tested disorders. Among those exposed to trauma, women were significantly more likely to develop PTSD, after controlling for assaultive violence. CONCLUSIONS: This study highlights the importance of investigating the prevalence of PTSD, patterns of co-morbidity of PTSD, and gender differences in PTSD in non-English-speaking countries.
