OBJECTIVES The US Department of Health and Human Services, in collaboration with the Congressional Black Caucus, created a new initiative to address the disproportionate ongoing HIV/AIDS crisis in racial/ethnic minority populations. METHODS This initiative included deploying technical assistance teams through the Office of HIV/AIDS Policy. The teams introduced rapid assessment and response methodologies and trained minority communities in their use. RESULTS The first 3 eligible cities (Detroit, Miami, and Philadelphia) focused assessments in small geographic areas, using multiple methodologies to obtain data. CONCLUSIONS Data from the first 3 eligible cities provided critical information about changing the dynamics of the HIV/AIDS epidemic at the local level, including program and policy changes and infrastructure redeployment targeted at the most serious social and environmental conditions.

INTRODUCTION Few studies have focused on the mental health consequences of indirect exposure to disasters caused by naturally occurring hazards. The present study assessed indirect exposure to the 2010 earthquake in Haiti among Haitian-Americans now living in Miami; these subjects had no direct exposure to the earthquake, but retained their cultural identity, language, and connection to family and friends in Haiti. METHODS Two months following the earthquake a sample of Haitian-Americans was surveyed inquiring about: (1) their psychological reactions to the quake; (2) types of exposures experienced by their family members and friends in Haiti; and (3) symptom levels of (a) major depression, (b) generalized anxiety disorder, (c) complicated grief, (d) mental health status, and (e) physical health status. RESULTS Haitian-Americans living in Miami experienced a broad spectrum of indirect exposures to the 2010 earthquake in Haiti. These exposures were strongly associated with psychological distress, trauma-related mental health consequences, and diminished health status. Most notable was the multiplicity of indirect exposures to the on-scene experiences of multiple family members and friends in Haiti. CONCLUSIONS Consideration should be given to the psychological impact and needs for support among indirectly-exposed populations with strong affiliation to directly-impacted victims.

The 2013–2016 West Africa Ebola virus disease pandemic was the largest, longest, deadliest, and most geographically expansive outbreak in the 40-year interval since Ebola was first identified. Fear-related behaviors played an important role in shaping the outbreak. Fear-related behaviors are defined as “individual or collective behaviors and actions initiated in response to fear reactions that are triggered by a perceived threat or actual exposure to a potentially traumatizing event. FRBs modify the future risk of harm.” This review examines how fear-related behaviors were implicated in (1) accelerating the spread of Ebola, (2) impeding the utilization of life-saving Ebola treatment, (3) curtailing the availability of medical services for treatable conditions, (4) increasing the risks for new-onset psychological distress and psychiatric disorders, and (5) amplifying the downstream cascades of social problems. Fear-related behaviors are identified for each of these outcomes. Particularly notable are behaviors such as treating Ebola patients in home or private clinic settings, the “laying of hands” on Ebola-infected individuals to perform faith-based healing, observing hands-on funeral and burial customs, foregoing available life-saving treatment, and stigmatizing Ebola survivors and health professionals. Future directions include modeling the onset, operation, and perpetuation of fear-related behaviors and devising strategies to redirect behavioral responses to mass threats in a manner that reduces risks and promotes resilience.

Earthquake Impact on Miami Haitian Americans: The Role of Family/Social Connectedness.

Andrea Allen; Louis Herns Marcelin; Susan Schmitz; Vicky Hausmann; James M. Shultz

Individuals who are indirectly exposed to disasters may be affected psychologically. The impact of the 2010 Haiti earthquake reverberated throughout the Haitian American community in Miami, Florida. Many within the community held strong transnational family and friendship bonds to their homeland. We examined associations between indicators of family and social connectedness and symptom levels for generalized anxiety disorder, major depression, and physical and mental health status for Haitian Americans and non-Haitian Americans who were living in Miami at the time of the earthquake. Results showed that family and social connectedness to earthquake victims strongly predicted symptom levels for Haitian American survey participants.

Response to Trauma in Haitian Youth at Risk

Richard Douyon; Louis Herns Marcelin; Michèle Jean-Gilles; J. Bryan Page

Abstract In order to characterize undesirable behavior (drug use, fighting, criminal activity) among Haitian youth at risk and determine the relationship between traumatic experience and that kind of behavior, investigators recruited 292 Haitian youths via networks of informal social relations in two zones of Miami/Dade County strongly identified with Haitian ethnicity. Each recruit responded to an interview schedule eliciting sociodemographic information and self-reported activities, including involvement in youth-dominated groups. They also reported traumatic experience. Clinicians administered CAPS to a subset of those respondents who self-reported traumatic experience. Staff ethnographers selected respondents for in-depth interviews and family studies to provide contextual depth for findings of the interview schedule and the CAPS assessments. Although traumatic experience may still play a role in mental health outcomes among children, childhood victimization among Haitian children does not appear to be related to the drug use and undesirable behaviors associated with unsupervised youth, including formation of gangs.

Abstract The objective of this article is to report on prevalence of drug and cigarette use among a segment of Haitian youth in the United States. The article is an argument in favor of contextualizing knowledge about drug use among young people across socioethnic lines. Because initiation of licit and illicit drugs tends to occur during adolescence, ethnic differentiation is crucial if we are to understand the drug experience among young people in the United States. Immigration, acculturation, and identity processes are critical in refuting the conventional racial categorization commonly used for interpretation of risks and behaviors among youth in the United States. The task of bringing empirical evidence to bear on drug use and drug choices by young people from different contexts will lead to the re-examination of patterns of drug use as well as to creative ways of conceptualizing these patterns.

Although physical violence against children is common worldwide, there are no national estimates in Haiti. To establish baseline national estimates, a three-stage clustered sampling design was utilized to administer a population-based household survey about victimization due to physical violence to 13-24 year old Haitians (n=2,916), including those residing in camps or settlements. Descriptive statistics and weighted analysis techniques were used to estimate national lifetime prevalence and characteristics of physical violence against children. About two-thirds of respondents reported having experienced physical violence during childhood (67.0%; 95% CI 63.4-70.4), the percentage being similar in males and females. More than one-third of 13-17 year old respondents were victimized in the 12 months prior to survey administration (37.8%; 95% CI 33.6-42.1). The majority of violence was committed by parents and teachers; and the perceived intent was often punishment or discipline. While virtually all (98.8%; 95% CI 98.0-99.3) victims of childhood physical violence were punched, kicked, whipped or beaten; 11.0% (95% CI 9.2-13.2) were subject to abuse by a knife or other weapon. Injuries sustained from violence varied by victim gender and perpetrator, with twice as many females (9.6%; 95% CI 7.1-12.7) than males (4.0%; 95% CI 2.6-6.1) sustaining permanent injury or disfigurement by a family member or caregiver (p-value<.001). Our findings suggest that physical violence against children in Haiti is common, and may lead to severe injury. Characterization of the frequency and nature of this violence provides baseline estimates to inform interventions.

ABSTRACT This Disaster Health Briefing focuses on the work of an expanding team of researchers that is exploring the dynamics of fear-related behaviors in situations of mass threat. Fear-related behaviors are individual or collective behaviors and actions initiated in response to fear reactions that are triggered by a perceived threat or actual exposure to a potentially traumatizing event. Importantly, fear-related behaviors modulate the future risk of harm. Disaster case scenarios are presented to illustrate how fear-related behaviors operate when a potentially traumatic event threatens or endangers the physical and/or psychological health, wellbeing, and integrity of a population. Fear-related behaviors may exacerbate harm, leading to severe and sometimes deadly consequences as exemplified by the Ebola pandemic in West Africa. Alternatively, fear-related behaviors may be channeled in a constructive and life-saving manner to motivate protective behaviors that mitigate or prevent harm, depending upon the nature of the threat scenario that is confronting the population. The interaction between fear-related behaviors and a mass threat is related to the type, magnitude, and consequences of the population encounter with the threat or hazard. The expression of FRBs, ranging from risk exacerbation to risk reduction, is also influenced by such properties of the threat as predictability, familiarity, controllability, preventability, and intentionality.

BACKGROUND AND OBJECTIVE: Globally, little evidence exists on sexual violence against boys. We sought to produce the first internationally comparable estimates of the magnitude, characteristics, risk factors, and consequences of sexual violence against boys in 3 diverse countries. METHODS: We conducted nationally representative, multistage cluster Violence Against Children Surveys in Haiti, Kenya, and Cambodia among males aged 13 to 24 years. Differences between countries for boys experiencing sexual violence (including sexual touching, attempted sex, and forced/coerced sex) before age 18 years were examined by using χ2 and logistic regression analyses. RESULTS: In Haiti, Kenya, and Cambodia, respectively, 1459, 1456, and 1255 males completed surveys. The prevalence of experiencing any form of sexual violence ranged from 23.1% (95% confidence Interval [CI]: 20.0–26.2) in Haiti to 14.8% (95% CI: 12.0–17.7) in Kenya, and 5.6% (95% CI: 4.0–7.2) in Cambodia. The largest share of perpetrators in Haiti, Kenya, and Cambodia, respectively, were friends/neighbors (64.7%), romantic partners (37.2%), and relatives (37.0%). Most episodes occurred inside perpetrators’ or victims’ homes in Haiti (60.4%), contrasted with outside the home in Kenya (65.3%) and Cambodia (52.1%). The most common time period for violence in Haiti, Kenya, and Cambodia was the afternoon (55.0%), evening (41.3%), and morning (38.2%), respectively. Adverse health effects associated with violence were common, including increased odds of transactional sex, alcohol abuse, sexually transmitted infections, anxiety/depression, suicidal ideation/attempts, and violent gender attitudes. CONCLUSIONS: Differences were noted between countries in the prevalence, characteristics, and risk factors of sexual violence, yet associations with adverse health effects were pervasive. Prevention strategies tailored to individual locales are needed.

Haiti and the politics of governance and community responses to Hurricane Matthew

Louis Herns Marcelin; Toni Cela; James M. Shultz

ABSTRACT This article examines disaster preparedness and community responses to Hurricane Matthew in semi-urban and rural towns and villages in Grande-Anse, Haiti. Based on an ethnographic study conducted in the department of Grande-Anse one week after the hurricane made landfall in Haiti, the article focuses on the perspectives of citizens, community-based associations and local authorities in the affected areas. Sixty-three (63) interviews and 8 community meetings (focus groups) were conducted in 11 impacted sites in 8 communes. Results suggest that preexisting conditions in impacted communities, rather than deliberate and coordinated disaster management strategies, shaped levels of preparedness for and response to the disaster. Affected populations relied primarily on family networks and local forms of solidarity to attend to basic needs such as shelter, health and food. The main argument presented is that Haiti, by virtue of its geographic location, lack of resources, institutional fragility and vulnerability, must systematically integrate community-based assets and capacities in its responses to and management of disasters. Further, it is critical for the government, Haitian institutions, and society to apply integrated risk reduction and management and disaster preparedness measures in all aspects of life, if the country is to survive the many disasters to come in a time of climate change. These measures should be embedded in recovery and reconstruction efforts after Hurricane Matthew.
