Violent Victimization, Mental Health, and Service Utilization Outcomes in a Cohort of Homeless and Unstably Housed Women Living With or at Risk of Becoming Infected With HIV

Experiences of violence and hospitalization rates among people living with HIV in British Columbia, Canada

People living with HIV (PLWH) in Canada experience high rates of interpersonal violence which may lead to adverse health outcomes that require hospitalization. Using self-reported data on experiences of violence linked to administrative health data on hospitalizations, we used Poisson regression modelling to examine and compare the associations between experiences of violence (recent [in the past 6 months], non-recent [>6 months ago], or none) and hospitalization rates, among a sample of PLWH in British Columbia, Canada. Of 984 PLWH included in this study, 60.0% reported experiencing non-recent violence, and 14.8% experienced recent violence. Those who experienced non-recent violence had a higher rate of hospitalization than those who never experienced violence (adjusted Rate Ratio [aRR]: 1.41; 95% Confidence Interval [CI]: 1.05-1.87). There was no difference in hospitalization rates between those who experienced recent violence and those who never did (aRR: 1.08; 95% CI: 0.74-1.60). PLWH who experienced recent violence had the highest proportion of hospitalizations attributed to mental, behavioural, or neurodevelopmental disorders. Efforts are needed to provide violence-aware care that recognizes violence and its impacts on PLWH experiencing multiple sociostructural inequities. Further studies should evaluate the impacts of violence on other types of healthcare utilization in generalizable samples of PLWH in Canada.

Adaptation of a mindfulness-based intervention for trauma-exposed, unhoused women with substance use disorder

OBJECTIVE

Women experiencing homelessness (WEH) report exceedingly high rates of trauma exposure, posttraumatic stress disorder (PTSD), and substance use disorder (SUD). Mindfulness-based interventions including Mindfulness-based Stress Reduction (MBSR) may help lower traumatic stress-related symptoms and reduce SUD, but have been underexplored in community-based settings serving WEH with symptoms of PTSD and SUD.

METHOD

We used a mixed-method, community-engaged approach that implemented a Community Advisory Board and the ADAPT-ITT (assessment, decision, adaptation, production, topical experts, integration, training, testing) framework, including intervention demonstrations, to adapt and refine MBSR for WEH experiencing symptoms of PTSD/SUD. Trauma-exposed WEH (N = 28) living at a drug treatment site provided perspectives and feedback on an MBSR demonstration via quantitative questionnaires and four focus groups.

RESULTS

Quantitative measures indicated high perceived acceptability and feasibility: Nearly all WEH reported MBSR activities (including yoga, meditation, body scans, class discussion, and home practice) would be at least "somewhat helpful"; between 71.43% to 89.29% reported each activity would be "a great deal helpful." Most reported the focus group sessions were useful for providing feedback relevant for improving program design and administration. Qualitative findings revealed four themes aligning with quantitative findings that provided useful suggestions to guide MBSR implementation with trauma-exposed WEH: (a) perception of feasibility and effectiveness of MBSR, (b) strategies for successful recruitment, (c) strategies for successful retention, and (d) characteristics of the MBSR trainer.

CONCLUSIONS

Focus group recommendations could bolster intervention compliance, engagement, and completion for MBSR and community-based programs for WEH more generally. Results provide suggestions for implementing a trauma-sensitive approach when administering MBSR to trauma-exposed WEH. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

The Effects of Traumatic Events on Mental Health Among Women Experiencing Homelessness: A Longitudinal Study

In this longitudinal study, we aim to evaluate the prevalence and impact of interpersonal and non-interpersonal traumatic events among women experiencing homelessness in Madrid (Spain) (N  =  136). The information was collected through a structured interview and standardized instruments at baseline and at a 12-month follow-up. The most prevalent events were physical assaults, intimate partner violence, and severe illnesses or accidents. Path analysis revealed that personal and non-interpersonal traumatic events had direct effects on mental health, but also had differential indirect effects. Greater efforts are needed to address the effects of various types of potentially traumatic events and to design effective trauma-informed interventions for women experiencing homelessness.

Homelessness, Discrimination, and Violent Victimization in Los Angeles County

INTRODUCTION

People experiencing homelessness (PEH) are highly vulnerable to discrimination and violence, which impact physical and mental health. The study examines past-month discrimination and violence against PEH in Los Angeles County (LAC).

METHODS

A total of 332 PEH in LAC were surveyed about their past-month experiences with discrimination, physical violence, and sexual violence from April-July 2023. Analyses were conducted in 2023.

RESULTS

31.8% of respondents reported experiencing discrimination daily and 53.9% reported it weekly, whereas rates of lifetime discrimination in studies of general populations of minoritized groups range between 13-60%. Nearly half of respondents who reported experiencing discrimination (49.6%) believed that their housing situation was the reason they were targeted. Victimization was also common, with 16.0% of participants experiencing physical violence and 7.5% experiencing sexual violence in the past 30 days. These rates of past-month victimization are high when compared to past-year physical violence (3.0%) and sexual violence (0.24%) among general populations in major U.S. cities. In multivariate regression analyses, discrimination was associated with being unsheltered in a vehicle (p<0.05) or outdoors (p<0.001), weekly illicit drug use (p<0.01), and psychological distress (p<0.001); violent victimization was associated with being sheltered (p<0.05) or unsheltered outdoors (p<0.001), physical health conditions (p<0.05), and psychological distress (p<0.01); and sexual victimization was associated with non-male gender (p<0.05) and being unsheltered outdoors (p<0.05). Discrimination and victimization outcomes were not associated with any race/ethnicity, sexual orientation, or time homeless characteristics.

CONCLUSIONS

Study findings highlight the dangers of homelessness in the U.S., particularly for those who are unsheltered outdoors.

Epidemiological features of depression and anxiety among homeless adults with healthcare access problems in London, UK: descriptive cross-sectional analysis

BACKGROUND

In England in 2021, an estimated 274 000 people were homeless on a given night. It has long been recognised that physical and mental health of people who are homeless is poorer than for people who are housed. There are few peer-reviewed studies to inform health and social care for depression or anxiety among homeless adults in this setting.

AIMS

To measure the symptoms of depression and anxiety among adults who are homeless and who have difficulty accessing healthcare, and to describe distribution of symptoms across sociodemographic, social vulnerability and health-related characteristics.

METHOD

We completed structured questionnaires with 311 adults who were homeless and who had difficulty accessing healthcare in London, UK, between August and December 2021. We measured anxiety and depression symptoms using the 4-item Patient Health Questionnaire (PHQ-4) score. We compared median PHQ-4 scores across strata of the sociodemographic, social vulnerability and health-related characteristics, and tested for associations using the Kruskal-Wallis test.

RESULTS

The median PHQ-4 score was 8 out of 12, and 40.2% had scores suggesting high clinical need. Although PHQ-4 scores were consistently high across a range of socioeconomic, social vulnerability and health-related characteristics, they were positively associated with: young age; food insecurity; recent and historic abuse; joint, bone or muscle problems; and frequency of marijuana use. The most common (60%) barrier to accessing healthcare related to transportation.

CONCLUSIONS

Adults who are homeless and have difficulty accessing healthcare have high levels of depression and anxiety symptoms. Our findings support consideration of population-level, multisectoral intervention.

HIV disclosure without consent linked to increased violence against women living with HIV in a Canadian setting

Our study examined the association between HIV disclosure without consent and verbal and/or physical violence due to HIV status among women living with HIV (WLWH). This study draws on baseline data of a sample (N = 316) from SHAWNA, a longitudinal community-based open cohort with WLWH in Metro Vancouver, Canada (2010-2019). Bivariate and multivariable logistic regression was used to investigate factors associated with physical and/or verbal violence due to HIV status. Adjusted odds ratios (AOR) and 95% confidence intervals [95%CIs] are reported. In total, 46.5% experienced non-consensual disclosure of HIV status without consent and 34.2% experienced physical and/or verbal violence related to HIV status in their lifetime. In multivariable analysis, HIV disclosure without consent was associated with increased odds of experiencing HIV-related physical and/or verbal violence (AOR: 7.46[4.21-13.21]). Lifetime exposure to homelessness was also associated with increased odds of physical and/or verbal violence due to HIV status (AOR: 2.15[1.03-4.49]). This research underscores the reality of HIV stigmatization and criminalization and suggests a critical need to remove HIV disclosure from the reach of criminal law and ensure women's rights to confidentiality. Governments and organizations must work to identify and address the drivers of various levels of stigma and gender-based violence and invest in inclusive, trauma-informed, culturally safe support and care programs and policies designed in collaboration with WLWH.

Physical and sexual victimization of persons with severe mental illness seeking care in central and southwestern Uganda

Purpose

This study established the prevalence of physical and sexual victimization, associated factors and psychosocial consequences of victimization among 1,201 out-patients with severe mental illness at Butabika and Masaka hospitals in Uganda.

Methods

Participants completed structured, standardized and locally translated instruments. Physical and sexual victimization was assessed using the modified adverse life events module of the European Para-suicide Interview Schedule. We used logistic regression to determine the association between victimization, the associated factors and psychosocial consequences.

Results

The prevalence of physical abuse was 34.1% and that of sexual victimization was 21.9%. The age group of > = 50 years (aOR 1.02;95% CI 0.62-1.66; p = 0.048) was more likely to have suffered physical victimization, while living in a rural area was protective against physical (aOR 0.59; 95% CI 0.46-0.76; p = <0.001) and sexual (aOR 0.48, 95% CI 0.35-0.65; p < 0.001) victimization. High socioeconomic status (SES) (aOR 0.56; 95% CI 0.34-0.92; p = <0.001) was protective against physical victimization. Females were more likely to have been sexually victimized (aOR 3.38; 95% CI 2.47-4.64; p = <0.001), while being a Muslim (aOR 0.60; 95% CI 0.39-0.90; p = 0.045) was protective against sexual victimization. Risky sexual behavior was a negative outcome associated with physical (aOR 2.19; 95% CI 1.66-2.90; p = <0.001) and sexual (aOR 3.09; 95% CI 2.25-4.23; p < 0.001) victimization. Mental health stigma was a negative outcome associated with physical (aOR 1.03; 95% CI 1.01-1.05; p < 0.001) and sexual (aOR 1.03; 95% CI 1.01-1.05; p = 0.002) victimization. Poor adherence to oral anti-psychotic medications was a negative outcome associated with physical (aOR 1.51; 95% CI 1.13-2.00; p = 0.006) and sexual (aOR 1.39; 95% CI 0.99-1.94; p = 0.044) victimization.

Conclusion

There is a high burden of physical and sexual victimization among people with SMI in central Uganda. There is need to put in place and evaluate complex interventions for improving detection and response to abusive experiences within mental health services. Public health practitioners, policymakers, and legislators should act to protect the health and rights of people with SMI in resource poor settings.

Contradictions hindering the provision of mental healthcare and psychosocial services to women experiencing homelessness in Addis Ababa, Ethiopia: service providers' and programme coordinators' experiences and perspectives

BACKGROUND

Mental health conditions are among the health issues associated with homelessness, and providing mental healthcare to people experiencing homelessness is challenging. Despite the pressing issue of homelessness in Addis Ababa, Ethiopia, there is scant research on how service providers address women's mental health and psychosocial needs. Therefore, we explored service providers' and programme coordinators' perceptions and experiences regarding mental healthcare and psychosocial services delivery to women experiencing street homelessness in the city.

METHODS

We conducted a descriptive qualitative study with selected healthcare and social support providers and programme coordinators. The study involved 34 participants from governmental and non-governmental organisations in Addis Ababa, Ethiopia. Data were analysed using an inductive thematic approach.

RESULTS

Four themes were derived from the analysis. The first of these was "divergent intentions and actions". While service providers and programme coordinators showed empathy and compassion, they also objectified and blamed people for their own homelessness. They also expressed opposing views on mental health stigma and compassion for these people. The second theme addressed "problem-solution incompatibility", which focused on the daily challenges of women experiencing homelessness and the types of services participants prioritised. Service providers and programme coordinators proposed non-comprehensive support despite the situation's complexity. The participants did not emphasise the significance of gender-sensitive and trauma-informed care for women experiencing street homelessness in the third theme, "the lack of gendered and trauma-informed care despite an acknowledgement that women face unique challenges". The fourth theme, "mismatched resources," indicated structural and systemic barriers to providing services to homeless women.

CONCLUSIONS

Conflicting attitudes and practices exist at the individual, organisational, and systemic levels, making it challenging to provide mental healthcare and psychosocial services to women experiencing homelessness. An integrated, gender-sensitive, and trauma-informed approach is necessary to assist women experiencing homelessness.

A scoping review of intimate partner violence in hospitalized patients

BACKGROUND

Despite the high prevalence and significant health effects of intimate partner violence (IPV), little is known about its associations with hospitalization.

OBJECTIVE

To perform a scoping review of how IPV impacts hospitalization rates, characteristics, and outcomes in adult patients.

DATA SOURCES

A search of four databases (MEDLINE, Embase, Web of Science, and CINAHL) using a combination of terms including hospitalized patients and IPV revealed 1608 citations.

STUDY SELECTION AND DATA EXTRACTION

One reviewer determined eligibility based on inclusion and exclusion criteria, which a second reviewer independently verified. Data were extracted and organized a posteriori into three categories based on research aim: (1) comparative studies of hospitalization risk associated with recent IPV exposure, (2) comparative studies of hospitalization outcomes by IPV exposure, and (3) descriptive studies of hospitalizations for IPV.

RESULTS

Of the 12 included studies, 7 were comparative studies of hospitalization risk associated with IPV, 2 were comparative studies of hospitalization outcomes by IPV, and 3 were descriptive studies of hospitalizations for IPV. Nine out of 12 studies focused on specific patient populations. All but one study demonstrated that IPV was associated with increased risk of hospitalization and/or worse hospitalization outcomes. Six of the seven comparative studies showed a positive association between recent IPV and hospitalization risk.

CONCLUSION

This review suggests that IPV exposure increases the risk of hospitalization and/or worsens inpatient outcomes in specific patient populations. Additional work is needed to characterize hospitalization rates and outcomes for persons who have experienced IPV in a broader, nontrauma population.

A multi-method exploration of mindfulness as a coping tool: Perspectives from trauma-exposed, unhoused women residing at a drug treatment facility

This multi-method study examined perspectives on mindfulness and coping strategies used by trauma-exposed women experiencing homelessness (WEH), residing in a state-funded residential drug treatment site in Southern California (United States). Questionnaires and in-depth focus group interviews were utilised to examine traumatic experiences over the lifespan, probable-posttraumatic stress disorder (PTSD), and coping strategies. Mindfulness was explored as a potential way to improve coping; potential benefits and challenges associated with implementing a mindfulness-based intervention (MBI) with trauma-exposed WEH were also investigated. A Community Advisory Board (CAB) was formed to identify key issues experienced by WEH and to develop a semi structured interview guide (SSIG). Using the SSIG, women participated in one of four focus groups (total N = 28; n = 7 per group). Quantitative data on demographic indicators, probable-PTSD, and trauma exposure were collected. Almost 90% of women met criteria for probable-PTSD; trauma exposure was exceedingly high; most women had experienced multiple traumas throughout their lives. Four main themes emerged from qualitative analyses, which drew from Grounded Theory and used open, selective, and axial coding: (1) ways of coping with trauma; (2) perspectives on mindfulness; (3) prior experiences with mindfulness; and (4) challenges for conducting a mindfulness programme. Overall, WEH used a variety of coping techniques to deal with their trauma, had some familiarity with mindfulness, and were optimistic an MBI would be helpful, despite identifying several challenges to implementation. MBIs may be helpful adjuncts to traditional care for trauma-exposed, WEH, recovering from substance use disorder. Population-specific considerations may improve implementation and participation.

Homelessness and Vulnerably-Housed Defined: A Synthesis of the Literature

There is no single accepted definition used in policy or research for the concepts of homelessness and vulnerably housed. Neuman's systems model (NSM) was the framework for this mixed-studies review, with the client system defined as these social issues and categorized as environmental stressors. Eighteen unique definitions of the concepts were identified in 30 studies. Extrapersonal stressors included housing history, interpersonal stressors included dependence on others for housing, and intrapersonal stressors included self-identification. Each level of stressor should be considered when defining these populations for inclusion in future research. Proposed definitions were formulated from the analysis of the results.

Ongoing tobacco use in women who experience homelessness and unstable housing: A prospective study to inform tobacco cessation interventions and policies

BACKGROUND

Tobacco use is common in people who experience homelessness. However, despite biological differences in use by sex and lower quit rates in women, research in homeless and unstably housed (HUH) women is sparse. We identified correlates of use specific to this population, with the goal of informing tobacco cessation programs tailored for HUH women.

METHODS

We conducted a prospective study among HUH women recruited from San Francisco homeless shelters, street encampments, free meal programs and low-income hotels. Between June 2016 and January 2019, study participants completed six monthly interviews to examine factors associated with tobacco use, defined as urinary cotinine >10 pg/mL or self-reported prior 30-day use.

RESULTS

Among 245 participants, 40% were Black, the median age was 53, 75% currently used tobacco and 89% had ≥one 24-hour quit attempt in the prior year. Tobacco use was more common in women with PTSD (66% vs. 48%) and depression (54% vs. 35%) compared to women without these conditions. Adjusted odds of tobacco use decreased significantly with increasing age (OR_{/5 yrs}: 0.81; 95% CI:0.68, 0.96) and increased with an increasing number of additional substances used (OR: 2.52; 95% CI: 1.88, 3.39).

CONCLUSION

Outside of a treatment setting and within a community-recruited sample population composed of HUH women, the number of additional substances used is a primary correlate of ongoing tobacco use. Tailored cessation interventions that prioritize the issue of multiple substance use, and public health policies that allocate funding to address it, may increase tobacco cessation in this population.

Adult frequent presentation to emergency departments and adverse childhood experiences: a scoping review

BACKGROUND

Extensive literature reports the influence of childhood adversity on adult health, however few studies have explored these life antecedents in people who frequently present to the emergency department. This review synthesizes literature exploring childhood adversity influences on emergency department presentations, if and how it is identified, and interventions addressing the health care needs of this group.

METHODS

Eight electronic databases were searched. Arksey and O'Malley's framework guided this review, and a quality appraisal was undertaken. Searches included all published studies until August 2020.

RESULTS

Twenty-one articles were included in this review. They revealed that childhood adversity is common among adults who frequently attend the emergency department. It impacts physical and psychological health into adulthood and there is no standardized approach described to documenting childhood adversity, nor any consistent intervention reported by emergency departments to address its sequelae in adulthood.

CONCLUSIONS

Several studies call for screening, intervention, and education to identify and address impacts of childhood adversity for patients who frequently present to the emergency department. However, reliable high-level studies exploring these topics specific to the emergency department are uncommon. Consequently, definitive interventions to address the healthcare needs of this group is lacking and warrants further research.

Persistent Homelessness and Violent Victimization Among Older Adults in the HOPE HOME Study

The homeless population is aging; older homeless adults may be at high risk of experiencing violent victimization. To examine whether homelessness is independently associated with experiencing physical and sexual abuse, we recruited 350 adults, aged 50 and older in Oakland, California, who met criteria for homelessness between July 2013 and June 2014. We interviewed participants at 6-month intervals for 3 years in Oakland about key variables, including housing status. Using generalized estimating equations, we examined whether persistent homelessness in each follow-up period was independently associated with having experienced physical or sexual victimization, after adjusting for known risk factors. The majority of the cohort was men (77.4%) and Black American (79.7%). At baseline, 10.6% had experienced either physical or sexual victimization in the prior 6 months. At 18-month follow-up, 42% of the cohort remained homeless. In adjusted models, persistent homelessness was associated with twice the odds of victimization (adjusted odds ratio [AOR] = 2.01; 95% confidence interval [CI]: [1.41, 2.87]). Older homeless adults experience high rates of victimization. Re-entering housing reduces this risk. Policymakers should recognize exposure to victimization as a negative consequence of homelessness that may be preventable by housing.

Gun violence against unhoused and unstably housed women: A cross-sectional study that highlights links to childhood violence

Background

Unstably housed women experience high levels of violence. While previous studies have investigated psychological, physical, and sexual violence, weapon and gun violence are rarely delineated. We examined factors associated with experiencing violence as an adult among unhoused and unstably housed women, with a focus on gun violence.

Methods

We recruited women with a history of housing instability from San Francisco homeless shelters, street encampments, free meal programs, low-income hotels, and health clinics. Participants completed interviews including questions regarding both childhood and adult violence. We used multivariable logistic regression to examine associations of specific types of childhood violence (i.e., physical, sexual, gun, other weapon-involved violence), age, race, ethnicity, educational attainment, and sexual orientation, with risk of experiencing specific types of violence as an adult (i.e., gun, other weapon-involved, physical violence). Because the violence outcomes were not rare, odds ratios were transformed to approximate risk ratios.

Results

Nearly half of women (n = 110, 45%) had been attacked with a gun as an adult. Violent victimization in adulthood was common, with 33% having experienced all three forms of violence. The probability of being attacked with a gun as an adult was almost 70% higher among women who had been hit or kicked hard enough to cause injury as a child (RR = 1.68; 95% CI = 1.24, 2.11), and this association was present for all three violence outcomes. No other risk factors explored, including other types of violence experienced as a child, met the statistical threshold to be considered significant.

Conclusions

The high prevalence of gun violence reported here is consistent with prior studies of violence conducted in similar populations. Considered in combination with prior research, findings suggest multi-generational violence prevention interventions for low-income women and girls are needed. They also emphasize the need to more actively include people who experience unstable housing in statewide and national violence surveys to better understand the extent of the problem and address on a broader scale the high rates of violence experienced by unstably housed populations, which have been consistently documented in local research.

A qualitative exploration of women's resilience in the face of homelessness

The aim of this study was to examine the experiential perspectives of women becoming and experiencing homelessness. Situated in the qualitative interpretative tradition, data were collected using auto-driven photo-elicitation and in-depth face-to-face interviews. Eleven Australian women used photographs that represented their experiences of being homeless to guide their interview discussion. The findings revealed that homelessness for women is a period often preceded by a series of adverse incidents in their lives, characterised by progressive resilience building in the face of trauma, finding hope and building strength to work towards exiting homelessness. After becoming homeless, five stages of resilience transition emerged: The trauma of homelessness, Finding hope and surviving, Finding help, Finding connection and Taking control. Women experiencing homelessness are resilient and capable of enacting competence and autonomy in seeking help to exit homelessness. Changes to service delivery are recommended to improve trauma-informed, person-centred housing and social services that are integrated and easy to navigate.

The Role of Stressful Life Events among Women Experiencing Homelessness: An Intragroup Analysis

The aim of this study is to examine stressful life events (SLEs) among homeless women and how SLEs were related to patterns and trajectories of homelessness. Specifically, the study aimed to replicate and build upon by Muñoz et al. (2005) by using cluster and discriminant analysis in a sample of 116 homeless women. The sample was classified based on SLEs, and the relationship between the resulting subgroups and sociodemographic characteristics, homeless trajectories, physical and mental health, and social support was examined. The results suggest that the three-cluster solution was theoretically and structurally meaningful: (a) the "Shorter homelessness trajectories and best health and mental health" subgroup was characterized by low levels of SLEs, a shorter homeless trajectory, lower prevalence of physical and mental health problems, and lower rates of alcohol and substances consumption; (b) the "Early onset of homelessness and poorer health and poorer mental health" subgroup was characterized by a higher prevalence of childhood and adolescence SLEs, an early onset of homelessness and greater chronification, mental health problems, and alcohol consumption; and (c) the "Chronic homelessness and poorest health and mental health" subgroup was mainly characterized by a higher prevalence of typically adulthood SLEs, as well as some SLEs that may be unique to women, a greater number of periods of homelessness, physical health problems, disabilities, and substance misuse. Increased knowledge about the different subgroups and trajectories of homeless women, as well as their specific characteristics and needs, will help us design social services and policies sensitive to all these differences.

The Relevance of Victimization Experiences for Predicting the Development of Threat Symptoms During Adolescence and Early Adulthood

The "threat" portion of the threat/control override symptom constellation is characterized by the belief by an individual that others seek to do them harm. There has yet to be an examination of the link between perceived threat symptomatology and the experience of victimization, despite the fact that both constructs are linked to the perpetration of violent behavior. Furthermore, there has yet to be research which examines the heterogeneity in developmental patterns of threat symptomatology. The present research utilized the Pathways to Desistance data to model the developmental heterogeneity in perceived threat symptomatology across adolescence and early adulthood using group-based trajectory modeling. A series of multinomial logistic regression models were then estimated to examine the relevance of victimization experiences for predicting trajectory group assignment. A five-group model of development during adolescence and early adulthood best fit the threat symptom data. Victimization experienced prior to age 16 predicted assignment to all groups in the model characterized by presentation of threat symptoms at some point during the study. Victimization experienced between ages 16 and 23 predicted assignment to the High Chronic group and marginally predicted assignment to the Accelerating group. These results indicate that victimization does indeed predict the presentation of perceived threat symptomatology. This indicates that presentation of threat symptoms may be indicative of a history of victimization. Proper screening of those presenting threat symptoms may help to better orient treatment plans for modalities centered on victimization experiences. Future research should investigate the possibility that threat symptoms mediate the relationship between victimization and violent behavior.

Combining Self-Determination Theory and Photo-Elicitation to Understand the Experiences of Homeless Women

Homelessness is a complex and gendered experience. To understand this complexity, novel theoretical frameworks and appropriate research methods are required. Most women living without homes have experienced some form of abuse or mental health issues before becoming, being or exiting homelessness and there is high prevalence of trauma in this vulnerable population. Researchers investigating women's homelessness need to ensure the research process is not retraumatising. This paper proposes a theoretical framework that combines self-determination theory (SDT) and photo-elicitation to support and guide research conducted with women who are at risk of negative effects of power imbalances and retraumatisation in research. The framework offers new opportunities to sensitively study women's homelessness by leveraging a strengths-based premise and empowering procedures to increase women's control in the research process. Embedding this method within the SDT research framework repositions women from objects of research to being competent, autonomous, active and empowered agents in the research process.

Improving Care Outcomes for PLWH Experiencing Homelessness and Unstable Housing: a Synthetic Review of Clinic-Based Strategies

PURPOSE OF REVIEW

Singular interventions targeting vulnerable populations of people living with HIV (PLWH) are necessary for reducing new infections and optimizing individual-level outcomes, but extant literature for PLWH who experience homelessness and unstable housing (HUH) has not been compiled. To inform implementation of clinic-based programs that improve care outcomes in this population, we present a synthetic review of key studies examining clinic-based interventions, specifically case management, patient navigation, financial incentives, and the use of mobile technology.

RECENT FINDINGS

Results from unimodal interventions are mixed or descriptive, are limited by inability to address related multi-modal barriers to care, and do not address major challenges to implementation. Multi-component interventions are needed, but gaps in our knowledge base may limit widespread uptake of such interventions before further data are compiled. Future research evaluating interventions for PLWH experiencing HUH should include implementation outcomes in order to facilitate adaptation across diverse clinical settings.

Risk of mental ill-health among homeless women in Madrid (Spain)

Several studies have revealed that homeless people suffering from mental health problems are more vulnerable than homeless without those mental health problems. Nevertheless, there is a lack of evidence describing the real circumstances of homeless women. This paper explores the differences between homeless women at high risk of mental ill-health compared with those who do not present this risk. The sample consisted of a group of 120 homeless women in Madrid (Spain). For this study, we collected data on background information (trajectory of homelessness and stressful life events experienced) and current aspects (living conditions, physical health, and social support). The risk of mental ill-health has been measured by the short version of the General Health Questionnaire (GHQ-28). The results showed that homeless women with higher risk of mental ill-health had become homeless at a younger age, had experienced more stressful life events in their lives, had a poorer physical health, felt less happy, had less social support, and a greater feeling of loneliness when compared with homeless women who did not present risk of mental ill-health. Improving knowledge about the risk of mental ill-health among homeless women is essential for the design of specific psychological interventions within this population.

Violence and Emergency Department Use among Community-Recruited Women Who Experience Homelessness and Housing Instability

Women who experience housing instability are at high risk for violence and have disproportionately high rates of emergency department (ED) use. However, little has been done to characterize the violence they experience, or to understand how it may be related to ED use. We recruited homeless and unstably housed women from San Francisco shelters, free meal programs, and single room occupancy (SRO) hotels. We used generalized estimating equations to examine associations between violence and any ED use (i.e., an ED visit for any stated reason) every 6 months for 3 years. Among 300 participants, 44% were African-American, and the mean age was 48 years. The prevalence of violence experienced in the prior 6 months included psychological violence (87%), physical violence without a weapon (48%), physical violence with a weapon (18%), and sexual violence (18%). While most participants (85%) who experienced physical violence with a weapon or sexual violence in the prior 6 months had not visited an ED, these were the only two violence types significantly associated with ED use when all violence types were included in the same model (ORphysical/weapon = 1.83, 95% CI 1.02-3.28; ORsexual = 2.15, 95% CI 1.30-3.53). Only violence perpetrated by someone who was not a primary intimate partner was significantly associated with ED use when violence was categorized by perpetrator. The need to reduce violence in this population is urgent. In the context of health care delivery, policies to facilitate trauma-informed ED care and strategies that increase access to non-ED care, such as street-based medicine, could have substantial impact on the health of women who experience homelessness and housing instability.

The effect of intimate partner violence on women's mental distress: a prospective cohort study of 3010 rural Indian women

PURPOSE

Intimate partner violence (IPV) encompasses physical, sexual, and psychological abuse, as well as controlling behavior. Most research focuses on physical and sexual abuse, and other aspects of IPV are rarely investigated. We estimated the effect of these neglected aspects of IPV on women's mental distress.

METHODS

We used data from 3010 women living in rural tribal communities in Rajasthan, India. Women completed baseline interviews and were re-interviewed approximately 1.5 years later. We measured IPV with questions adopted from the Demographic and Health Survey's Domestic Violence Module, which asked seven questions about physical abuse, three questions about psychological abuse, and five questions about partner controlling behavior. Mental distress was measured with the 12-item General Health Questionnaire (score range 0-12). We used Poisson regression models to estimate the relation between changes in IPV and mental distress, accounting for time-fixed characteristics of individuals using individual fixed effects.

RESULTS

Women reported an average of 2.1 distress symptoms during baseline interviews. In models that controlled for time-varying confounding (e.g., wealth, other types of abuse), experiencing psychological abuse was associated with an increase of 0.65 distress symptoms (95% CI 0.32, 0.98), and experiencing controlling behavior was associated with an increase of 0.31 distress symptoms (95% CI 0.18, 0.44). However, experiencing physical abuse was not associated with an increase in distress symptoms (mean difference = - 0.15, 95% CI - 0.45, 0.15).

CONCLUSIONS

Psychological abuse and controlling behavior may be important drivers of the relation between IPV and women's mental health.

Housing First: Unsuppressed Viral Load Among Women Living with HIV in San Francisco

While poverty is an established barrier to achieving success at each step of the HIV care continuum, less is known about specific aspects of poverty and how they overlap with behavior in exceptionally low-income individuals who live in well-resourced areas. We considered unsuppressed viral load over 3 years among women living with HIV in San Francisco who used homeless shelters, low-income hotels and free meal programs. One-hundred twenty study participants were followed; 60% had > 1 unsuppressed viral load and 19% were unsuppressed at every visit. Across six-month intervals, the odds of unsuppressed viral load were 11% higher for every 10 nights spent sleeping on the street [Adjusted Odds Ratio (AOR) 1.11, 95% CI 1.02-1.20]; 16% higher for every 10 nights spent sleeping in a shelter (AOR/10 nights 1.16, 95% CI 1.06-1.27); 4% higher for every 10 nights spent sleeping in a single-room occupancy hotel (AOR/10 nights 1.04, 95% CI 1.02-1.07); and over threefold higher among women who experienced any recent incarceration (AOR 3.56, 95% CI 1.84-6.86). Violence and recent use of outpatient health care did not significantly predict viral suppression in adjusted analysis. While strategies to promote retention in care are important for vulnerable persons living with HIV, they are insufficient to ensure sustained viral suppression in low-income women experiencing homelessness and incarceration. Results presented here in combination with prior research linking incarceration to homelessness among women indicate that tailored interventions, which not only consider but prioritize affordable housing, are critical to achieving sustained viral suppression in low-income women living with HIV.

Depression, injecting drug use, and risky sexual behavior syndemic among women who inject drugs in Kenya: a cross-sectional survey

BACKGROUND

Injecting drug use (IDU) is a key driver of the HIV epidemic particularly when individuals experience psychosocial conditions and risky sexual behavior in a syndemic manner. This study sets out to assess evidence of a syndemic pattern of psychosocial conditions (IDU, depression, intimate partner violence (IPV)) on one the hand and risky sexual behavior on the other while accounting for the socio-economic disadvantage among women who inject drugs (WWID) in low-income urban settings in Kenya.

METHODS

Using a cross-sectional study design, this study recruited 306 WWIDs from two sites in Nairobi between January 2017 and July 2017. Multiple methodologies including descriptive analyses of co-occurrences of psychosocial conditions at the individual level, standard logistic regression analyses to examine relationships and interactions within and between psychosocial conditions and risky sexual behavior, and classification trees algorithm for predictive modeling via machine learning were employed.

RESULTS

The prevalence of the psychosocial conditions was as follows: IDU, 88%; depression, 77.1%; and IPV, 84%. The prevalence of risky sexual behavior was 69.3%. IDU and depression were related to each other (P < 0.05) and each of them with risky sexual behavior (P < 0.05). The highest 2-way and 3-way co-occurrence of conditions were reported in IDU and depression (72%) and in IDU, depression, and risky sexual behavior (62%), respectively, indicating clustering of the conditions at the individual level. Further, each additional psychosocial condition (IDU and depression) was associated with sixfold odds (P = 0.000) of having risky sexual behavior suggesting a dose-response relationship. Logistic regression analyses incorporating multiplicative interactive effects returned three significant variables (P < 0.05): IDU*depression interaction effect, "Age when delivered the first child," and "Income." Classification tree modeling represented a 5-level interaction analysis with IDU and depression predicted to have the highest influence on risky sexual behavior.

CONCLUSION

Findings provide possible evidence of a syndemic pattern involving IDU, depression, and risky sexual behavior suggesting the need for an integrated approach to the implementation of harm reduction interventions among WWID in low-income urban settings in Kenya. This work highlights the need for further studies to authenticate the findings and to characterize pathways in the syndemic development in WWID.

Condomless Sex and Psychiatric Comorbidity in the Context of Constrained Survival Choices: A Longitudinal Study Among Homeless and Unstably Housed Women

We sought to identify the prevalence and independent correlates of condomless sex within a cohort of community-recruited homeless and unstably housed cisgender adult women who were followed biannually for 3 years (N = 143 HIV+ , N = 139 HIV-). Nearly half (44%) of participants reported condomless sex in the 6 months before baseline, which increased to 65% throughout the study period. After adjusting for having a primary partner, longitudinal odds of condomless sex among women with HIV were significantly higher among those reporting < daily use of alcohol or cannabis (AOR = 2.09, p =.002, and 1.88, p =.005, respectively) and PTSD (AOR = 1.66, p =.034). Among women without HIV, adjusted longitudinal odds of condomless sex were significantly higher for those reporting < daily methamphetamine use (AOR = 2.02, p =.012), panic attack (AOR = 1.74, p =.029), and homelessness (AOR = 1.67, p = .006). Associations were slightly attenuated when adjusting for sex exchange. Targeted HIV/STI programs for unstably housed women should address anxiety and trauma disorders, infrequent substance use, and housing challenges.

Food insecurity and intimate partner violence among married women in Nepal

Background

Intimate Partner Violence (IPV) is an important public health concern globally, including in Nepal. Food insecurity (being without reliable access to a sufficient quantity of affordable, nutritious food) has been associated with IPV, but no known studies have explored this relationship in South Asia, or Nepal specifically. Women’s level of empowerment is an important factor to consider when understanding the relationship between food insecurity and IPV.

Methods

Using data from the 2011 Nepal Demographic and Health Survey, we explore the relationship between different levels of food insecurity (none, mild, moderate, severe) and three types of IPV: physical, sexual and emotional. In a second set of models we adjust for indicators of women’s empowerment. We use multi-variable logistic regression to test for an association between these factors, adjusting for individual and household level demographic variables.

Findings

About half of married women in our sample experience food insecurity and approximately 10% of women experienced each of the three different types of IPV in the past 12 months: emotional, sexual and physical. Food insecurity is significantly associated with increased odds of experiencing emotional (odds ratio OR = 1.75 95% confidence interval CI = 1.06-2.77 for severe food insecurity) or physical (OR = 2.48, 95% CI = 1.52-4.04 for severe food insecurity) IPV, but not sexual IPV, after adjusting for individual and household level demographic variables. After adjusting for empowerment related factors, this relationship still holds, although it is somewhat attenuated. Women’s level of household decision-making power is significantly associated with higher odds of emotional, sexual and physical IPV, and whether she lives with her in-laws is protective against emotional IPV.

Conclusions

Among married women in Nepal, being food insecure is associated with higher odds of some types of IPV, specifically emotional and physical IPV. Accounting for women’s level of empowerment explains some of the relationship between food insecurity and IPV. It is essential that interventions to prevent IPV address household stressors such as food insecurity among married, Nepalese women, perhaps through cross-sectoral approaches. Such structural interventions are likely to reduce IPV for married women across South Asia who live in a similar levels of gender discrimination and food insecurity.

Community collective efficacy is associated with reduced physical intimate partner violence (IPV) incidence in the rural province of Mpumalanga, South Africa: findings from HPTN 068

BACKGROUND

Intimate partner violence (IPV) is a human rights violation and is associated with a variety of adverse physical and mental health outcomes. Collective efficacy, defined as mutual trust among community members and willingness to intervene on the behalf of the common good, has been associated with reduced neighbourhood violence. Limited research has explored whether community collective efficacy is associated with reduced incidence of IPV. This is of particular interest among adolescent girls and young women (AGYW) in sub-Saharan Africa, where the burden of HIV is greatest and IPV is common.

METHODS

We collected longitudinal data among 2533 AGYW (ages 13-20) enrolled in the HPTN 068 cohort in Mpumalanga province, South Africa between 2011 and 2016. We included participants from 26 villages where community surveys were collected during the HPTN 068 study. Collective efficacy was measured at the village level via two population-based cross-sectional surveys in 2012 and 2014. Multivariable Poisson generalised estimating equation regression models estimated the relative risk ratio (RR) between village collective efficacy scores and subsequent physical IPV 12 month incidence, adjusting for village-level clustering and covariates.

RESULTS

Thirty-eight per cent of the cohort (n=950) reported at least one episode of recent physical IPV during follow-up. For every SD higher level of collective efficacy, there was a 6% lower level of physical IPV incidence (adjusted RR: 0.94; 95% CI 0.89 to 0.98) among AGYW after adjusting for covariates.

CONCLUSIONS

Community-level interventions that foster the development of collective efficacy may reduce IPV among AGYW.

Estimating the Relative Excess Risk Due to Interaction in Clustered-Data Settings

The risk difference scale is often of primary interest when evaluating public health impacts of interventions on binary outcomes. However, few investigators report findings in terms of additive interaction, probably because the models typically used for binary outcomes implicitly measure interaction on the multiplicative scale. One measure with which to assess additive interaction from multiplicative models is the relative excess risk due to interaction (RERI). The RERI measure has been applied in many contexts, but one limitation of previous approaches is that clustering in data has rarely been considered. We evaluated the RERI metric for the setting of clustered data using both population-averaged and cluster-conditional models. In simulation studies, we found that estimation and inference for the RERI using population-averaged models was straightforward. However, frequentist implementations of cluster-conditional models including random intercepts often failed to converge or produced degenerate variance estimates. We developed a Bayesian implementation of log binomial random-intercept models, which represents an attractive alternative for estimating the RERI in cluster-conditional models. We applied the methods to an observational study of adverse birth outcomes in mothers with human immunodeficiency virus, in which mothers were clustered within clinical research sites.

The Cedar Project: exploring determinants of psychological distress among young Indigenous people who use drugs in three Canadian cities

BACKGROUND

Mental health and wellbeing, including addressing impacts of historical trauma and substance use among young people, has been identified as a key priority by Indigenous communities and leaders across Canada and globally. Yet, research to understand mental health among young Indigenous people who have used drugs is limited.

AIMS

To examine longitudinal risk and strengths-based factors associated with psychological distress among young Indigenous people who use drugs.

METHOD

The Cedar Project is an ongoing cohort study involving young Indigenous people who use drugs in Vancouver, Prince George, and Chase, British Columbia, Canada. This study included participants who completed the Symptom Checklist-90-Revised, returned for follow-up between 2010 and 2012, and completed the Childhood Trauma Questionnaire. Adjusted linear mixed-effects models estimated effects of study variables on changes in area T-scores of psychological distress.

RESULTS

Of 202 eligible participants, 53% were women and the mean age was 28 years. Among men, childhood maltreatment (emotional abuse, physical abuse, sexual abuse, physical neglect), any drug use, blackouts from drinking, and sex work were associated with increased distress. Among women, childhood maltreatment (emotional abuse, physical abuse, physical neglect), blackouts from drinking, and sexual assault were associated with increased distress, while having attempted to quit using drugs was associated with reduced distress. Marginal associations were observed between speaking their traditional language and living by traditional culture with lower distress among men.

CONCLUSION

Culturally safe mental wellness interventions are urgently needed to address childhood trauma and harmful coping strategies that exacerbate distress among young Indigenous people who use drugs.

Associations between medical cannabis and other drug use among unstably housed women

BACKGROUND

Several studies suggest that U.S. state-level legalization of cannabis for medical purposes may be associated with reductions in opioid use; yet its relationship with stimulant use, particularly in high-risk populations like unstably housed women, has received less attention. The purpose of this study was to estimate independent associations between medical and non-medical use of cannabis and use of stimulants and opioids among unstably housed women.

METHODS

Cross-sectional data were analyzed from 245 women in the SHADOW study, a community based cohort in San Francisco, CA, in which HIV+ women were oversampled (126 HIV+ and 119 HIV-).

RESULTS

Compared to no cannabis use in the past 6 months (51%), non-medical cannabis use (28%) was associated with a higher adjusted odds of using stimulants (Adjusted Odds Ratio [AOR]=4.34, 95% confidence interval [CI]: 2.17-8.70) and opioids (AOR=3.81, 95% CI: 1.78-8.15). Compared to no cannabis use, medical cannabis use (21%) was not significantly associated with stimulant or opioid use. Compared to non-medical cannabis use, however, medical cannabis use was associated with lower adjusted odds of using stimulants (AOR=0.42, 95% CI: 0.18-0.96). These associations were not modified by HIV status.

CONCLUSIONS

Associations between use of cannabis and "street drugs" depend on whether the cannabis is obtained through a medical context. Interventions, research, and policy considering the influence of cannabis on the use of other drugs may benefit by distinguishing between medical and non-medical cannabis use.

Differential effects of perceived stress on alcohol consumption in moderate versus heavy drinking HIV-infected women

OBJECTIVE

To examine the association between perceived stress and subsequent alcohol use in women living with HIV.

METHODS

Women (n=338) receiving HIV care between April 2006 and July 2010 who enrolled in either a brief intervention for hazardous drinking or a cohort of non-hazardous drinkers completed a 90-day drinking and drug use history, and completed stress, depression and anxiety measures at 0, 6, and 12 months. We examined the association between perceived stress at months 0 or 6 and measures of quantity and frequency of alcohol use in months 3-6 and 9-12, respectively.

RESULTS

The association between perceived stress and subsequent alcohol use depended on whether women were heavy or moderate drinkers at index visit. Among women reporting ≥7 drinks/week at index visit, high levels of perceived stress were associated with subsequent increased alcohol intake. However, among women reporting >0 but <7 drinks/week at index visit, high levels of perceived stress were associated with a subsequent reduction in drinking.

CONCLUSIONS

Baseline drinking status moderates the relationship between perceived stress and subsequent alcohol use. Perceived stress is an important therapeutic target in women who are heavy drinkers.

Psychiatric Risk in Unstably Housed Sexual Minority Women: Relationship between Sexual and Racial Minority Status and Human Immunodeficiency Virus and Psychiatric Diagnoses

BACKGROUND

Stress associated with minority statuses has been linked to mental health disorders. However, research conducted exclusively among impoverished women, a population known to be at risk for poor health owing to overlapping risks, is sparse. We sought to determine if homeless and unstably housed sexual minority (i.e., nonheterosexual) women were at greater psychiatric risk than their heterosexual counterparts. We also sought to determine if racial/ethnic minority and human immunodeficiency virus status contributed to psychiatric risks.

METHODS

Homeless/unstably housed women living in San Francisco between 2008 and 2010 were followed biannually over 3 years. Generalized estimating equation analysis identified significant correlates of any substance use, mood, or anxiety disorder, as well as the total number of psychiatric disorders.

RESULTS

Among 300 women, 24% reported nonheterosexual identity at the first study visit. Consistent with minority stress theory, lesbian and bisexual identity were associated with higher levels of mental health comorbidity, and bisexual identity was related to greater rates of substance use disorders and mood disorders. Unique to this study, we found that identity assessed 1 or 2 years prior does not predict current substance disorders, but current identity does. In addition, women who were infected with the human immunodeficiency virus also had higher rates of mental health comorbidity and substance use disorders. Contrary to psychosocial stress theory, racial/ethnic minority status was associated with reduced odds of substance use disorder in this population. Recent homelessness was related to greater risk of anxiety disorder.

CONCLUSIONS

Best research and health care practices should include the assessment of sexual orientation and housing status when addressing risks for mental health and substance disorders among low-income women.

Mental ill health in structural pathways to women's experiences of intimate partner violence

Background

Depression, post-traumatic stress disorder (PTSD), and binge drinking are among mental health effects of child abuse and intimate partner violence (IPV) experiences among women. Emerging data show the potential mediating role of mental ill health in the relationship of child abuse and IPV. There is evidence that PTSD, depression and alcohol abuse are comorbid common mental disorders and that a bidirectional relationship exists between depression and IPV in some settings. Furthermore, the temporal direction in the relationship of alcohol abuse and women’s IPV experiences from different studies is unclear. We undertook a study with women from the general population to investigate the associations of child abuse, mental ill health and IPV; and describe the underlying pathways between them.

Methods

Data is from a household survey employing a multi-stage random sampling approach with 511 women from Gauteng, South Africa. IPV was measured using the WHO Multi-country Study on Women's Health and Domestic Violence Questionnaire. Child abuse was measured using a short form of the Childhood Trauma Questionnaire. Depression was measured using the Centre for Epidemiologic Studies Depression Scale (CESD). PTSD symptoms were measured using the Harvard Trauma Questionnaire. Binge drinking was measured using the Alcohol Use Disorders Identification Test (AUDIT) scale. All data analyses were conducted in Stata 13. Regression modelling was used to test the association between variables. Structural equation modelling with full information maximum likelihood estimation accounting for missing data was done to analyse the underlying pathways between variables.

Results

Fifty percent of women experienced IPV in their lifetime and 18% experienced IPV in the 12 months before the survey. Twenty three percent of women were depressed, 14% binge drank and 11.6% had PTSD symptoms. Eighty six percent of women had experienced some form of child abuse. Sociodemographic factors associated with recent IPV in multivariate models were younger age and foreign nationality. Depression, PTSD and binge drinking mediated the relationship of child abuse and recent IPV. Depression, PTSD and binge drinking were also effects of recent IPV. Other factors associated with recent IPV experience included relationship control, having a partner who regularly consumed alcohol and experiencing other life traumatic experiences

Conclusion

Mental ill health plays a mediating role in the relationship of child abuse and recent IPV experiences among women. Conversely, IPV also negatively affects women’s mental health. Interventions to reducing the incidence of IPV could help alleviate the burden of mental ill health among women and vice versa. Effective integration of mental health services in primary health care, detection of symptoms, brief interventions and strengthened referral mechanisms for sustained community-based care are necessary in responding to victims of intimate partner violence. Response for abused children needs to take similar approaches and reduce the long-term mental health effects associated with violent exposures.

Multiple Types of Childhood and Adult Violence Among Homeless and Unstably Housed Women in San Francisco

This study examined the relationship between different forms of childhood violence (emotional, physical, and sexual) and these same forms of violence in adulthood, using a crosssectional baseline survey of 298 homeless and unstably housed women in San Francisco, California. We also examined other related factors, including mental illnesses diagnosis, sex exchange, jail time, HIV status, and sociodemographic information. Regression analysis indicated that although several of these factors were associated with experiences of violence as an adult, specific types of child violence (e.g., sexual violence) predicted instances of that same type of violence as an adult but not necessarily other types. Thus, risk of adult violence among low-income women may be better predicted and addressed through histories of same-type childhood violence, despite years of intervening exposures and stressors.

Prospective Study of the Mental Health Consequences of Sexual Violence Among Women Living With HIV in Rural Uganda

The association between sexual violence and depression is well known, but the temporal aspects of the association have not been well established. We analyzed data from a cohort of 173 HIV-positive women in rural Uganda who were interviewed every 3 months for a median of 1.8 years of follow-up. The method of generalized estimating equations (GEE) was used to model the marginal expectation of depression symptom severity (Hopkins Symptom Checklist for Depression), mental health-related quality of life (MOS-HIV Mental Health Summary), and heavy drinking (Alcohol Use Disorders Identification Test) as a function of self-reported forced-sex victimization in the 3 months prior to interview. Estimates were adjusted for variables known to confound the association between victimization and mental health status. To assess any potential reciprocal relationships, we reversed the temporal ordering of the exposures and outcomes and refitted similar GEE models. In multivariable analyses, victimization was associated with greater depression symptom severity (b = 0.17; 95% CI = [0.02, 0.33]) and lower mental health-related quality of life (b = -5.65; 95% CI = [-9.34, -1.96]), as well as increased risks for probable depression (adjusted relative risk [ARR] = 1.58; 95% CI = [1.01, 2.49) and heavy drinking (ARR = 3.99; 95% CI = [1.84, 8.63]). We did not find strong evidence of a reciprocal relationship. Our findings suggest that forced sex is associated with adverse mental health outcomes among HIV-positive women in rural Uganda. Given the substantial mental health-related impacts of victimization, effective health sector responses are needed.

Syndemics and Health Disparities: A Methodological Note

In the theory of syndemics, diseases are hypothesized to co-occur in particular temporal or geographical contexts due to harmful social conditions (disease concentration) and to interact at the level of populations and individuals, with mutually enhancing deleterious consequences for HIV risk (disease interaction). Since its original elaboration more than 20 years ago, the epidemiological literature on syndemic problems has followed a questionable trajectory, stemming from the use of a specific type of regression model specification that conveys very little information about the theory of syndemics. In this essay we critically review the dominant approaches to modeling in the literature on syndemics; highlight the stringent assumptions implicit in these models; and describe some meaningful public health implications of the resulting analytical ambiguities. We conclude with specific recommendations for empirical work in this area moving forward.

Intimate Partner Violence and Depression Symptom Severity among South African Women during Pregnancy and Postpartum: Population-Based Prospective Cohort Study

BACKGROUND

Violence against women by intimate partners remains unacceptably common worldwide. The evidence base for the assumed psychological impacts of intimate partner violence (IPV) is derived primarily from studies conducted in high-income countries. A recently published systematic review identified 13 studies linking IPV to incident depression, none of which were conducted in sub-Saharan Africa. To address this gap in the literature, we analyzed longitudinal data collected during the course of a 3-y cluster-randomized trial with the aim of estimating the association between IPV and depression symptom severity.

METHODS AND FINDINGS

We conducted a secondary analysis of population-based, longitudinal data collected from 1,238 pregnant women during a 3-y cluster-randomized trial of a home visiting intervention in Cape Town, South Africa. Surveys were conducted at baseline, 6 mo, 18 mo, and 36 mo (85% retention). The primary explanatory variable of interest was exposure to four types of physical IPV in the past year. Depression symptom severity was measured using the Xhosa version of the ten-item Edinburgh Postnatal Depression Scale. In a pooled cross-sectional multivariable regression model adjusting for potentially confounding time-fixed and time-varying covariates, lagged IPV intensity had a statistically significant association with depression symptom severity (regression coefficient b = 1.04; 95% CI, 0.61-1.47), with estimates from a quantile regression model showing greater adverse impacts at the upper end of the conditional depression distribution. Fitting a fixed effects regression model accounting for all time-invariant confounding (e.g., history of childhood sexual abuse) yielded similar findings (b = 1.54; 95% CI, 1.13-1.96). The magnitudes of the coefficients indicated that a one-standard-deviation increase in IPV intensity was associated with a 12.3% relative increase in depression symptom severity over the same time period. The most important limitations of our study include exposure assessment that lacked measurement of sexual violence, which could have caused us to underestimate the severity of exposure; the extended latency period in the lagged analysis, which could have caused us to underestimate the strength of the association; and outcome assessment that was limited to the use of a screening instrument for depression symptom severity.

CONCLUSIONS

In this secondary analysis of data from a population-based, 3-y cluster-randomized controlled trial, IPV had a statistically significant association with depression symptom severity. The estimated associations were relatively large in magnitude, consistent with findings from high-income countries, and robust to potential confounding by time-invariant factors. Intensive health sector responses to reduce IPV and improve women's mental health should be explored.

Communal bereavement and resilience in the aftermath of a terrorist event: Evidence from a natural experiment

RATIONALE

Sociological analyses of the psychological distress experienced by persons indirectly exposed to traumatic stressors have been conceptualized as a form of communal bereavement, defined by Catalano and Hartig (2001) as the experience of distress among persons not attached to the deceased. Their theory predicts communal bereavement responses particularly in the setting of loss of essential state, religious, or economic institutions.

OBJECTIVE

To estimate the extent to which the September 11, 2001 attacks on the U.S. World Trade Center had a causal effect on psychological distress nationwide.

METHODS

We used a difference-in-differences framework applied to repeated cross-sectional data from more than 300,000 participants in the 2000 and 2001 Behavioral Risk Factor Surveillance System surveys. Psychological distress was measured using three questions eliciting days of poor mental health-related quality of life. The September 11 attacks served as our exposure of interest.

RESULTS

The September 11 attacks had a statistically significant, adverse, causal effect on psychological distress nationally. Both the magnitude and statistical significance of the estimated effects were larger in the New York City region compared to the rest of the country. Our estimates were robust to probes of the parallel trends assumption and potential sources of selection bias, as well as to falsification tests. However, these effects had largely resolved within four weeks.

CONCLUSIONS

Contrary to findings from the medical and public health literature, we conclude that the September 11 attacks did not have lasting effects on communal bereavement.

A Review of Recent Literature on Trauma Among Individuals Living with HIV

Persons living with HIV (PLWH) report disproportionately high levels of exposure to traumatic events in childhood and adulthood. Traumatic experiences are associated with negative health and behavioral outcomes. Current research in this area seeks to further explicate the myriad health effects of trauma on PLWH and the pathways through which trauma operates. In this paper, we review articles published in English between January 2014 and June 2015 that examine traumatic experiences among PLWH, including intimate partner violence (IPV), domestic abuse, child abuse, and other forms of violence. A selection of studies examining trauma among PLWH and its associations with mental health, antiretroviral medication adherence, clinical outcomes, HIV disclosure, and sexual risk behaviors were included. Studies describing trauma coping strategies and interventions were also included. We conclude with recommendations for care of trauma-exposed PLWH and directions for future research.

Syndemics of psychosocial problems and HIV risk: A systematic review of empirical tests of the disease interaction concept

In the theory of syndemics, diseases co-occur in particular temporal or geographical contexts due to harmful social conditions (disease concentration) and interact at the level of populations and individuals, with mutually enhancing deleterious consequences for health (disease interaction). This theory has widespread adherents in the field, but the extent to which there is empirical support for the concept of disease interaction remains unclear. In January 2015 we systematically searched 7 bibliographic databases and tracked citations to highly cited publications associated with the theory of syndemics. Of the 783 records, we ultimately included 34 published journal articles, 5 dissertations, and 1 conference abstract. Most studies were based on a cross-sectional design (32 [80%]), were conducted in the U.S. (32 [80%]), and focused on men who have sex with men (21 [53%]). The most frequently studied psychosocial problems were related to mental health (33 [83%]), substance abuse (36 [90%]), and violence (27 [68%]); while the most frequently studied outcome variables were HIV transmission risk behaviors (29 [73%]) or HIV infection (9 [23%]). To test the disease interaction concept, 11 (28%) studies used some variation of a product term, with less than half of these (5/11 [45%]) providing sufficient information to interpret interaction both on an additive and on a multiplicative scale. The most frequently used specification (31 [78%]) to test the disease interaction concept was the sum score corresponding to the total count of psychosocial problems. Although the count variable approach does not test hypotheses about interactions between psychosocial problems, these studies were much more likely than others (14/31 [45%] vs. 0/9 [0%]; χ2 = 6.25, P = 0.01) to incorporate language about "synergy" or "interaction" that was inconsistent with the statistical models used. Therefore, more evidence is needed to assess the extent to which diseases interact, either at the level of populations or individuals, to amplify HIV risk.
