High prevalence of childhood emotional, physical and sexual trauma among a Canadian cohort of HIV-seropositive illicit drug users

Effects of Early-Life Adversities on Neuropsychiatric and Executive Functions in HIV-Positive Adults

OBJECTIVE

Adverse childhood experiences (ACEs) contribute to elevations in neuropsychiatric and neurocognitive symptoms in HIV+ adults. Emerging data suggest that exposures to threat-related and deprivation-related ACEs may have differential impacts on function, with threat exposure contributing to neuropsychiatric symptoms, and deprivation contributing to executive dysfunction. Yet, it remains unclear how specific types of ACEs impact neuropsychiatric and neurocognitive symptoms in HIV+ adults. Hence, the current study examined whether these two dimensions of adversity contribute differentially to neuropsychiatric symptoms and executive dysfunction in HIV+ adults.

METHODS

We included a sample of demographically matched HIV+ (N = 72) and HIV-negative (N = 85) adults. Standardized self-report measures assessed threat-related (interpersonal violence) and deprivation-related (poverty/neglect) ACEs, as well as neuropsychiatric symptoms (depression, anxiety, apathy). A brief battery of neuropsychological tests assessed executive functions.

RESULTS

Compared to HIV-negative participants, HIV+ participants reported significantly higher rates of threat exposure (51% vs. 67%, p = .04), while rates of deprivation did not differ significantly (8% vs. 13%, p = .38). In the HIV+ sample, threat exposure was associated with neuropsychiatric symptoms (p < .01) but not executive dysfunction (p = .75). By contrast, deprivation was associated with executive dysfunction, at a trend level (p = .09), but not with neuropsychiatric symptoms (p = .70).

CONCLUSIONS

Our data suggest that, relative to HIV-negative samples, HIV+ samples experience higher rates of threat-related ACEs, which contribute to neuropsychiatric symptom elevations. Moreover, our preliminary findings suggest that different types of ACEs could be associated with different profiles of neuropsychiatric and neurocognitive difficulty in HIV+ adults, highlighting the importance of considering dimensions of adversity in future studies.

Psychological Aspects of Child Maltreatment

In this review, we provide information about the etiology, risk factors, and clinical presentations of maltreatment to help clinicians better understand child abuse and neglect. Child maltreatment is a major global health challenge that can result in severe consequences. Abused and neglected children are likely to develop psychiatric disorders, such as major depressive disorder, anxiety disorder, and posttraumatic stress disorder. Understanding child maltreatment is expected to prevent and reduce victimization in children, adolescents, and their families.

A Systematic Review of Gender-Based Violence Prevention and Response Interventions for HIV Key Populations: Female Sex Workers, Men Who Have Sex With Men, and People Who Inject Drugs

Gender-based violence (GBV) is that perpetrated based on sex, gender identity, or perceived adherence to socially defined gender norms. This human rights violation is disproportionately experienced by HIV key populations including female sex workers (FSW), people who inject drugs (PWID), and men who have sex with men (MSM). Consequently, addressing GBV is a global priority in HIV response. There is limited consensus about optimal interventions and little known about effectiveness. Our systematic review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and was registered in International Prospective Register of Systematic Reviews. Peer-reviewed and non-peer-reviewed literature were searched for articles that described a GBV prevention or response intervention specifically for key populations including FSW, PWID, and MSM. Results were organized by level(s) of implementation and pillars of a comprehensive GBV response: prevention, survivor support, and accountability/justice. Of 4,287 articles following removal of duplicates, 32 unique interventions (21 FSW, seven PWID, and nine MSM, not mutually exclusive) met inclusion criteria, representing 13 countries. Multisectoral interventions blended empowerment, advocacy, and crisis response with reductions in violence. Individual-level interventions included violence screening and response services. Violence-related safety promotion and risk reduction counseling within HIV risk reduction programming reduced violence. Quantitative evaluations were limited. Violence prevention and response interventions for FSW, PWID, and MSM span individual, community, and multisectoral levels with evidence of promising practices at each level. The strongest evidence supported addressing violence in the context of sexually transmitted infection/HIV risk reduction. As interventions continue to emerge, the rigor of accompanying evaluations must simultaneously advance to enable clarity on the health and safety impact of GBV prevention and response programming.

Psychedelic use is associated with reduced daily opioid use among people who use illicit drugs in a Canadian setting

BACKGROUND

Research into the therapeutic and naturalistic uses of psychedelics for improving outcomes related to mental health disorders has generated increasing interest in recent years. While controlled clinical trials of psychedelics have signaled benefits for treating substance use disorders, this area has not been well studied in the context of naturalistic psychedelic use. This study sought to investigate the possible relationship between recent naturalistic psychedelic use and subsequent daily illicit opioid use among people who use drugs (PWUD).

METHODS

Data (2006-2018) were drawn from three harmonized prospective cohorts of community-recruited PWUD in Vancouver, Canada. We used multivariable generalized linear mixed-effects modeling (GLMM) to estimate the independent association between psychedelic use and subsequent daily illicit opioid use.

RESULTS

Among 3813 PWUD at baseline, 1093 (29%) reported daily use of illicit opioids and 229 (6%) reported psychedelic use in the past six months. Over study follow-up after adjusting for a range of potential confounders, psychedelic use remained independently associated with a significantly reduced odds of subsequent daily opioid use (Adjusted Odds Ratio: 0.45; 95% Confidence Interval: 0.29 to 0.70).

CONCLUSION

While confirmation in other settings is required, these findings align with growing evidence that psychedelic use may be associated with detectable reductions in subsequent substance use including illicit opioid use.

Assessing the Effects of Childhood Multitype Maltreatment on Adult Spirituality

Continued research regarding the effects of experiencing multiple types of childhood maltreatment is necessary in gauging the impact of such experiences on survivors. In an effort to contribute to this area of study, the authors investigated the relationship between multitype childhood maltreatment and adult spirituality and compared three established methods of assessing the these effects to investigate the degree to which a researcher's choice of method might affect their findings. Surveys were completed by 254 university students that included data on childhood maltreatment and current spirituality. Findings suggest the presence of a dose response between multitype childhood maltreatment and adult spirituality and that the researcher's assessment method choice can affect findings of the research. In addition, the authors report their findings on the unique effects of five types of childhood maltreatment on adult spirituality. Emotional neglect and emotional abuse were found to be associated with lower levels of spirituality; no significant relationships were found between sexual abuse, physical abuse, and physical neglect and spirituality. The findings suggest the need for further study regarding the effects of experiencing multiple types of childhood maltreatment, the most accurate methods of assessing those effects on survivors, and the relationship between multitype maltreatment and spirituality.

Child Maltreatment and Persistent Smoking From Adolescence Into Adulthood: A Birth Cohort Study

OBJECTIVE

A prospective record-linkage analysis to examine whether notified and/or substantiated child maltreatment is associated with the prevalence and persistence of smoking in early adulthood.

METHODS

The sample consisted of 3758 participants enrolled in a population-based birth cohort study in Brisbane, Australia, who were followed up at both 14 and 21 years of age. Suspected experience of child maltreatment was measured by linkage with state child protection agency data. The two main outcomes were the prevalence and persistence of smoking at 21-year follow-up, as well as the 12-month prevalence of nicotine use disorder for participants who completed the Composite International Diagnostic Interview-Auto version.

RESULTS

Of the 3758 young people at the 21-year follow-up, 7.5% (n = 282) had a history of notified maltreatment by the age of 16 years. Of these, 167 cases were substantiated. There were 1362 (35.3%) smokers at 21-year follow-up, although only 220 (5.9%) smoked more than 20 cigarettes daily. Of the 602 participants who smoked at 14 years, 289 were still smoking 7 years later. On adjusted analyses, participants who had experienced any form of notified and/or substantiated maltreatment were approximately twice as likely to be smokers at 21 years old and persistent smokers from 14 years of age. Any form of maltreatment, except sexual abuse, was also associated with an increase in the 12-month prevalence of nicotine use disorders.

CONCLUSIONS

Child maltreatment is associated with both an increased onset and persistence of smoking from adolescence into young adulthood. This may have implications for smoking cessation programs and early interventions for individuals who have experienced maltreatment.

Suicide risk in people living with AIDS/HIV: the effect of childhood trauma is mediated by mental disorders and social vulnerability

Suicide is an important problem in people living with HIV/AIDS (PLWHA). The importance of mental disorders and social vulnerability on suicidal behaviors is described in the literature; however, the impact of childhood traumatic events in this scenario is not clear. The aim of this study was to verify the mediation effect of mental disorder comorbidities and social vulnerability in association with childhood trauma intensity and suicide risk level. This cross-sectional study of HIV-positive outpatients was conducted in a specialized care service in the city of Pelotas in Southern Brazil. Sociodemographic data and HIV-related information were collected and the Childhood Trauma Questionnaire was applied. A total of 364 patients underwent psychiatric evaluation using MINI Plus including module C of suicide risk severity. Suicide risk was present in 39.3% of the sample. The relation between childhood traumatic events and the level of suicide risk is mediated by mental disorder comorbidities and socioeconomic vulnerability. Specific psychosocial interventions in PLWHA should consider the potential role of abusive traumatic experiences in the current mental health conditions and suicidal behaviors.

Predictors of Antiretroviral Adherence Self-efficacy Among People Living With HIV/AIDS in a Canadian Setting

BACKGROUND

Suboptimal adherence to antiretroviral therapy (ART) among people living with HIV/AIDS (PLWHA) who use illicit drugs remains an ongoing health concern. Although health outcomes associated with adherence self-efficacy have been well-documented, there is dearth research exploring the predictors of this construct. This study sought to identify possible determinants of adherence self-efficacy among a cohort of PLWHA who use illicit drugs.

METHODS

From December 2004 to May 2014, we collected data from the AIDS Care Cohort to evaluate Exposure to Survival Services, a prospective cohort of adult PLWHA who use illicit drugs in Vancouver, Canada. We used multivariate generalized estimating equation analyses to identify longitudinal factors independently associated with higher adherence self-efficacy.

RESULTS

Among 742 participants, 493 (66.4%) identified as male and 406 (54.7%) reported white ancestry. In multivariate generalized estimating equation analysis, older age at ART initiation (adjusted odds ratio [AOR] = 1.02, 95% confidence interval [CI]: 1.00 to 1.03) and recent year of baseline interview (AOR = 1.08, 95% CI: 1.05 to 1.11) were independently associated with higher adherence self-efficacy, whereas homelessness (AOR = 0.78, 95% CI: 0.65 to 0.94), ≥daily crack smoking (AOR = 0.81, 95% CI: 0.68 to 0.96), experienced violence (AOR = 0.82, 95% CI: 0.69 to 0.98), and childhood abuse (AOR = 0.75, 95% CI: 0.60 to 0.92) were negatively associated.

CONCLUSIONS

These findings highlight the potential role that personal and contextual factors can play in predicting levels of ART adherence self-efficacy. Future research should seek to identify and validate strategies to optimize adherence self-efficacy.

Childhood Trauma and the Inability to Access Hospital Care Among People who Inject Drugs

Childhood traumatic experiences can disrupt attachment, influence personality development, and precipitate chronic disease. Although the repercussions of these experiences may also pose a barrier to healthcare, few studies have examined the association between childhood trauma and access to healthcare. Therefore, we sought to investigate whether a history of childhood trauma is associated with self-reported inability to access hospital care among persons who inject drugs (PWID). Data were derived from two prospective cohorts of PWID in Vancouver, Canada. We used multivariable generalized estimating equations to examine associations between five types of childhood trauma and self-reported inability to access hospital care, both overall and specifically due to perceived mistreatment by hospital staff. In total, 300 participants (18.3%) reported having tried but being unable to access hospital care in the previous 6 months at some point during the study period; the primary reason was perceived mistreatment by hospital staff (32.1%). In multivariable analyses, childhood emotional abuse was independently associated with self-reported inability to access hospital care, adjusted odds ratio (AOR) = 1.51, 95% CI [1.03, 2.20]. Childhood physical neglect was also independently associated with inability to access care due to perceived mistreatment by hospital staff, AOR = 1.80, 95% CI [1.11, 2.93]. This suggests potentially damaging consequences of early trauma in adult PWID populations. Further, this study emphasizes the need for trauma-informed models of care as well as the need to improve therapeutic alliances with survivors of childhood trauma in the PWID population.

High early life stress and aberrant amygdala activity: risk factors for elevated neuropsychiatric symptoms in HIV+ adults

Relative to HIV-negative adults, HIV+ adults report elevated levels of early life stress (ELS). In non-HIV samples, high ELS has been linked to abnormalities in brain structure and function, as well as increased risk of neuropsychiatric symptoms. Yet, little is known about the neural effects of high ELS, and their relation to elevated neuropsychiatric symptoms, in HIV+ adults. Recent studies have revealed combined effects of HIV and high ELS on amygdala morphometry. Aberrant amygdala activity is prominently implicated in studies of neuropsychiatric symptomology in non-HIV samples. Hence, this preliminary study examined: 1) the combined effects of HIV and high ELS on amygdala activity, and 2) the relation between amygdala activity and neuropsychiatric symptoms in HIV+ adults. We included 28 HIV+ adults and 25 demographically-matched HIV-negative control (HC) adults. ELS exposure was quantified using a retrospective ELS questionnaire, which defined four groups: HIV+ Low-ELS (N = 15); HIV+ High-ELS (N = 13); HC Low-ELS (N = 16); and HC High-ELS (N = 9). Participants completed a battery of neuropsychiatric measures. BOLD fMRI assessed amygdala reactivity during explicit observation of fearful/angry faces. High-ELS participants demonstrated reduced levels of amygdala reactivity relative to Low-ELS participants. HIV+ High-ELS participants reported higher levels of neuropsychiatric symptoms than all other groups. In the HIV+ group, lower amygdala responses were associated with higher neuropsychiatric symptoms, particularly depression, anxiety, and alexithymia. Collectively, these results suggest that high ELS exposure is a significant risk factor for neuropsychiatric symptoms in HIV+ adults. Furthermore, our results implicate ELS-related abnormalities in amygdala activity in the etiology of neuropsychiatric symptoms in HIV+ adults.

Childhood Adversities and Physical and Mental Health Outcomes in Adults Living with HIV: Findings from the Ontario HIV Treatment Network Cohort Study

We sought to estimate the prevalence of childhood adversity and examine its relationship with health outcomes among people living with HIV. Study participants included 1409 adults living with HIV and receiving care in Toronto, Canada. Data on childhood adversity, health behaviors, HIV outcome measures, depression, and health-related quality of life (HRQOL) were collected through face-to-face interviews and medical records. Statistical analyses included multivariable linear and logistic regression modeling. The prevalence of any childhood adversity was 71% (individual types ranged from 11% to 44%) and higher prevalence was associated with younger age, Indigenous or African/Caribbean/Black ethnicity, lower socioeconomic status, and higher rates of cigarette smoking and nonmedicinal drug use. Greater number of childhood adversities was associated with greater odds of depression and decreasing mental HRQOL. HIV care providers need to screen for childhood adversities and address childhood trauma within the context of HIV care.

Effects of HIV and childhood trauma on brain morphometry and neurocognitive function

A wide spectrum of neurocognitive deficits characterises HIV infection in adults. HIV infection is additionally associated with morphological brain abnormalities affecting neural substrates that subserve neurocognitive function. Early life stress (ELS) also has a direct influence on brain morphology. However, the combined impact of ELS and HIV on brain structure and neurocognitive function has not been examined in an all-female sample with advanced HIV disease. The present study examined the effects of HIV and childhood trauma on brain morphometry and neurocognitive function. Structural data were acquired using a 3T Magnetom MRI scanner, and a battery of neurocognitive tests was administered to 124 women: HIV-positive with ELS (n = 32), HIV-positive without ELS (n = 30), HIV-negative with ELS (n = 31) and HIV-negative without ELS (n = 31). Results revealed significant group volumetric differences for right anterior cingulate cortex (ACC), bilateral hippocampi, corpus callosum, left and right caudate and left and right putamen. Mean regional volumes were lowest in HIV-positive women with ELS compared to all other groups. Although causality cannot be inferred, findings also suggest that alterations in the left frontal lobe, right ACC, left hippocampus, corpus callosum, left and right amygdala and left caudate may be associated with poorer neurocognitive performance in the domains of processing speed, attention/working memory, abstraction/executive functions, motor skills, learning and language/fluency with these effects more pronounced in women living with both HIV and childhood trauma. This study highlights the potential contributory role of childhood trauma to brain alterations and neurocognitive decline in HIV-infected individuals.

Housing Status, Medical Care, and Health Outcomes Among People Living With HIV/AIDS: A Systematic Review

BACKGROUND

Accumulating evidence suggests responses to HIV that combine individual-level interventions with those that address structural or contextual factors that influence risks and health outcomes of infection. Housing is such a factor. Housing occupies a strategic position as an intermediate structural factor, linking "upstream" economic, social, and cultural determinants to the more immediate physical and social environments in which everyday life is lived. The importance of housing status for HIV prevention and care has been recognized, but much of this attention has focused on homeless individuals as a special risk group. Analyses have less often addressed community housing availability and conditions as factors influencing population health or unstable, inadequate, or unaffordable housing as a situation or temporary state. A focus on individual-level characteristics associated with literal homelessness glosses over social, economic, and policy drivers operating largely outside any specific individual's control that affect housing and residential environments and the health resources or risk exposures such contexts provide.

OBJECTIVES

We examined the available empirical evidence on the association between housing status (broadly defined), medical care, and health outcomes among people with HIV and analyzed results to inform future research, program development, and policy implementation.

SEARCH METHODS

We searched 8 electronic health and social science databases from January 1, 1996, through March 31, 2014, using search terms related to housing, dwelling, and living arrangements and HIV and AIDS. We contacted experts for additional literature.

SELECTION CRITERIA

We selected articles if they were quantitative analyses published in English, French, or Spanish that included at least 1 measure of housing status as an independent variable and at least 1 health status, health care, treatment adherence, or risk behavior outcome among people with HIV in high-income countries. We defined housing status to include consideration of material or social dimensions of housing adequacy, stability, and security of tenure.

DATA COLLECTION AND ANALYSIS

Two independent reviewers performed data extraction and quality appraisal. We used the Cochrane Risk of Bias Tool for randomized controlled trials and a modified version of the Newcastle Ottawa Quality Appraisal Tool for nonintervention studies. In our quality appraisal, we focused on issues of quality for observational studies: appropriate methods for determining exposure and measuring outcomes and methods to control confounding.

RESULTS

Searches yielded 5528 references from which we included 152 studies, representing 139,757 HIV-positive participants. Most studies were conducted in the United States and Canada. Studies examined access and utilization of HIV medical care, adherence to antiretroviral medications, HIV clinical outcomes, other health outcomes, emergency department and inpatient utilization, and sex and drug risk behaviors. With rare exceptions, across studies in all domains, worse housing status was independently associated with worse outcomes, controlling for a range of individual patient and care system characteristics.

CONCLUSIONS

Lack of stable, secure, adequate housing is a significant barrier to consistent and appropriate HIV medical care, access and adherence to antiretroviral medications, sustained viral suppression, and risk of forward transmission. Studies that examined the history of homelessness or problematic housing years before outcome assessment were least likely to find negative outcomes, homelessness being a potentially modifiable contextual factor. Randomized controlled trials and observational studies indicate an independent effect of housing assistance on improved outcomes for formerly homeless or inadequately housed people with HIV. Housing challenges result from complex interactions between individual vulnerabilities and broader economic, political, and legal structural determinants of health. The broad structural processes sustaining social exclusion and inequality seem beyond the immediate reach of HIV interventions, but changing housing and residential environments is both possible and promising.

History of sexual, emotional or physical abuse and psychiatric comorbidity in substance-dependent patients

Sexual, emotional or physical abuse history is a risk factor for mental disorders in addicted patients. However, the relationship between addiction and abuse lifespan is not well known. This study aims to compare clinical and psychopathological features of addicted patients according to the experience of abuse and to the number of different types of abuse suffered. Bivariate and multivariate analyses were conducted. 512 addicted patients seeking treatment were included, 45.9% reported abuse throughout life (38.9% emotional, 22.3% physical and 13.5% sexual abuse). It was found that female gender; depressive symptoms and borderline personality disorder were independently associated with history of any abuse throughout life. As well, it was found that 14% have been suffered from all three types of abuse (sexual, emotional and physical), 34.5% from two and 55.5% from one type. Female gender and borderline personality disorder were independently associated independently with a greater number of different types of abuse. Results suggest that history of abuse is frequent among substance-dependent patients and these experiences are more prevalent in women and are associated with more psychiatric comorbidity.

Childhood Sexual Abuse and Syringe Sharing Among People Who Inject Drugs

Childhood sexual abuse is associated with adverse health outcomes. However, the impact of sexual abuse on HIV risk behaviors among people who inject drugs (IDU) has not been thoroughly characterized. We therefore sought to identify whether childhood sexual abuse was associated with syringe sharing among a sample of IDU in Vancouver, Canada. We assessed sexual abuse among two cohorts of IDUs via the Childhood Trauma Questionnaire. Multivariate logistic regression was used to estimate the relationship between childhood sexual abuse and syringe sharing. In total, 1380 IDU were included in the study, and 426 (30.9 %) IDU reported childhood sexual abuse. Syringe sharing (Adjusted Odds Ratio = 1.83, 95 % Confidence Interval 1.28-2.60) remained independently associated with childhood sexual abuse after adjustment for potential confounders. Given that a history of childhood sexual abuse appears to be elevated among IDU who engage in HIV risk behaviors (i.e., syringe sharing), HIV prevention efforts should include efforts to address historical trauma in this population.

Associations between childhood trauma and non-fatal overdose among people who inject drugs

INTRODUCTION

Although people who inject drugs (IDU) remain at a high risk of accidental overdose, interventions that address overdose remain limited. Accordingly there is a continuing need to identify psychological and social factors that shape overdose risk. Despite being reported frequently among IDU, childhood trauma has received little attention as a potential risk factor for overdose. This study aims to evaluate relationships between non-fatal overdose and five forms of childhood maltreatment among a cohort of IDU in Vancouver, Canada.

METHODS

Data was obtained from two prospective cohorts of IDU between December 2005 and May 2013. Multivariate generalized estimating equations (GEEs) were used to explore relationships between five forms of childhood trauma and non-fatal overdose, adjusting for potential confounders.

RESULTS

During the study period, 1697 IDU, including 552 (32.5%) women, were followed up. At baseline, 1136 (67.0%) participants reported at least one form of childhood trauma, while 4-9% reported a non-fatal overdose at each semi-annual follow-up. In multivariate analyses, physical [adjusted odds ratio (AOR): 1.36, 95% confidence interval (CI): 1.08-1.71], sexual (AOR: 1.48, CI: 1.17-1.87), and emotional abuse (AOR: 1.54, CI: 1.22-1.93) and physical neglect (AOR: 1.28, CI: 1.01-1.62) were independently associated with non-fatal overdose (all p<0.05).

CONCLUSIONS

Childhood trauma was common among participants, and reporting an experience of trauma was positively associated with non-fatal overdose. These findings highlight the need to provide intensive overdose prevention to trauma survivors and to incorporate screening for childhood trauma into health and social programs tailored to IDU.

Childhood maltreatment and the persistence of smoking: a longitudinal study among adults in the US

The current study examined the relationship between childhood maltreatment-emotional, physical, and severe physical maltreatment-and the initiation and persistence of smoking. Data were drawn from the Midlife Development in the United States (MIDUS) Survey Waves 1 and 2. Frequency of childhood emotional, physical, and severe physical maltreatment (never, rare, intermittent, frequent) reported at Wave 1 was examined in relation to ever smoking, smoking daily, and persistent daily smoking at Waves 1 and 2. Logistic regression analyses were used to calculate odds ratios (with 95% confidence intervals), which were then adjusted for potential confounders. Childhood emotional, physical, and severe physical maltreatment were associated with increased odds of ever smoking, smoking daily, and persistent smoking at Waves 1 and 2. The majority of these associations remained significant after adjusting for confounding variables. These results suggest a history of trauma may play a prominent role in recalcitrant cigarette smoking and suggest that the success rates of treatments for smoking cessation may be improved by integrating trauma treatment where appropriate.

Feasibility of providing interventions for injection drug users in pharmacy settings: a case study among San Francisco pharmacists

In addition to syringe exchange programs, pharmacies are important venues where injection drug users (IDUs) can access non-prescription syringes and other prevention interventions. This study assessed the feasibility of providing a range of interventions for IDUs in pharmacy settings. Semi-structured qualitative interviews were conducted with 23 participants (policy makers, owner/managers, dispensing pharmacists, and pharmacy staff) from independent and chain/retail pharmacies in San Francisco, California, USA. The highest level of support was for a coupon syringe program and educational materials. Several overarching themes illustrate challenges to implementing pharmacy-based preventive interventions: time, space, sufficient staff, pharmacist training, legal considerations, pharmacist attitudes toward IDUs, and cost and reimbursement issues. This study provides concrete examples of the types of preventive services that pharmacists support and consider feasible, and illustrates that pharmacists welcome the opportunity to broaden their role as critical partners in public health matters related to injection drug use.

The impact of childhood abuse on inpatient substance users: specific links with risky sex, aggression, and emotion dysregulation

Adults with substance use disorders (SUDs) report a high prevalence of childhood abuse. Research in the general population suggests specific types of abuse lead to particular negative outcomes; it is not known whether this pattern holds for adults with SUDs. We hypothesized that specific types of abuse would be associated with particular behavioral and emotional outcomes among substance users. That is, childhood sexual abuse would be associated with risky sex behaviors, childhood physical abuse with aggression, and childhood emotional abuse with emotion dysregulation. 280 inpatients (M age=43.3; 69.7% male; 88.4% African American) in substance use treatment completed the Childhood Trauma Questionnaire (CTQ), HIV Risk-Taking Behavior Scale, Addiction Severity Index, Difficulties with Emotion Regulation Scale (DERS), Distress Tolerance Scale (DTS), and Affect Intensity and Dimensions of Affiliation Motivation (AIM). Consistent with our hypotheses, the CTQ sexual abuse subscale uniquely predicted exchanging sex for cocaine and heroin, number of arrests for prostitution, engaging in unprotected sex with a casual partner during the prior year, and experiencing low sexual arousal when sober. The physical abuse subscale uniquely predicted number of arrests for assault and weapons offenses. The emotional abuse subscale uniquely predicted the DERS total score, AIM score, and DTS score. Among substance users, different types of abuse are uniquely associated with specific negative effects. Assessment of specific abuse types among substance users may be informative in treatment planning and relapse prevention.

The impact of childhood emotional abuse on violence among people who inject drugs

INTRODUCTION AND AIMS

Childhood emotional abuse is a known risk factor for various poor social and health outcomes. While people who inject drugs (IDU) report high levels of violence, in addition to high rates of childhood maltreatment, the relationship between childhood emotional abuse and later life violence within this population has not been examined.

DESIGN AND METHODS

Cross-sectional data were derived from an open prospective cohort of IDU in Vancouver, Canada. Childhood emotional abuse was measured using the Childhood Trauma Questionnaire. We used multivariate logistic regression to examine potential associations between childhood emotional abuse and being a recent victim or perpetrator of violence.

RESULTS

Between December 2005 and May 2013, 1437 IDU were eligible for inclusion in this analysis, including 465 (32.4%) women. In total, 689 (48.0%) reported moderate to severe history of childhood emotional abuse, whereas 333 (23.2%) reported being a recent victim of violence and 173 (12.0%) reported being a recent perpetrator of violence. In multivariate analysis, being a victim of violence (adjusted odds ratio = 1.49, 95% confidence interval 1.15-1.94) and being a perpetrator of violence (adjusted odds ratio = 1.58, 95% confidence interval 1.12-2.24) remained independently associated with childhood emotional abuse.

DISCUSSION AND CONCLUSIONS

We found high rates of childhood emotional abuse and subsequent adult violence among this sample of IDU. Emotional abuse was associated with both victimisation and perpetration of violence. These findings highlight the need for policies and programmes that address both child abuse and historical emotional abuse among adult IDU.

Early life emotional neglect and HIV risk taking among men using the Internet to find other men for unprotected sex

PURPOSE

Using a Syndemics Theory conceptual model, this study examines the relationship between emotional neglect experiences during childhood and/or adolescence and involvement in HIV risk taking in a sample of adult men who actively seek partners for unprotected sex via the Internet.

METHODS

The study was based on a national random sample of 332 MSM who use the Internet to seek men with whom they can engage in unprotected sex. Data collection was conducted via telephone interviews between January 2008 and May 2009. Structural equation analysis was undertaken to examine the specific nature of the relationships involved in understanding HIV risk practices.

RESULTS

Emotional neglect was highly prevalent among the men participating in this study. Emotional neglect experiences were not found to be related directly to involvement in HIV risk taking in adulthood. Emotional neglect, was found to be an important variable in the overall structural equation. Its effect on HIV risk taking was indirect, operating principally by having a negative impact upon self-esteem, which in turn had a negative effect on attitudes toward condom use, which in turn were related strongly and directly to risk taking.

CONCLUSIONS

Childhood experiences with emotional neglect are relevant to understanding HIV risk practices among MSM in adulthood, but the relationship is not as simple as usually conceptualized. Rather, emotional neglect appears to impact risk taking indirectly, through its effects on mental health functioning, which in turn affects risk-related attitudes.

Integrating adolescent substance abuse treatment with HIV services: evidence-based models and baseline descriptions

Adolescents with substance use disorders are at high risk for contracting Human Immunodeficiency Virus (HIV)/Acquired Immunodeficiency Syndrome (AIDS) and other sexually transmitted infections (STIs). Adolescence is the period of sexual maturation that compounds the issues associated with infection transmission for this risk-taking group. Integrated treatment models for implementing HIV education, counseling, and testing is a promising approach. This study describes four substance abuse treatment programs of varying levels of care that integrated HIV services for adolescents. Additionally, the evidence-based substance abuse treatment and HIV models are discussed and the baseline characteristics presented. The authors provide a discussion and offer recommendations for service implementation and additional research.

Childhood maltreatment and psychopathology: A case for ecophenotypic variants as clinically and neurobiologically distinct subtypes

OBJECTIVE

Childhood maltreatment increases risk for psychopathology. For some highly prevalent disorders (major depression, substance abuse, anxiety disorders, and posttraumatic stress disorder) a substantial subset of individuals have a history of maltreatment and a substantial subset do not. The authors examined the evidence to assess whether those with a history of maltreatment represent a clinically and biologically distinct subtype.

METHOD

The authors reviewed the literature on maltreatment as a risk factor for these disorders and on the clinical differences between individuals with and without a history of maltreatment who share the same diagnoses. Neurobiological findings in maltreated individuals were reviewed and compared with findings reported for these disorders.

RESULTS

Maltreated individuals with depressive, anxiety, and substance use disorders have an earlier age at onset, greater symptom severity, more comorbidity, a greater risk for suicide, and poorer treatment response than nonmaltreated individuals with the same diagnoses. Imaging findings associated with these disorders, such as reduced hippocampal volume and amygdala hyperreactivity, are more consistently observed in maltreated individuals and may represent a maltreatment-related risk factor. Maltreated individuals also differ from others as a result of epigenetic modifications and genetic polymorphisms that interact with experience to increase risk for psychopathology.

CONCLUSIONS

Phenotypic expression of psychopathology may be strongly influenced by exposure to maltreatment, leading to a constellation of ecophenotypes. While these ecophenotypes fit within conventional diagnostic boundaries, they likely represent distinct subtypes. Recognition of this distinction may be essential in determining the biological bases of these disorders. Treatment guidelines and algorithms may be enhanced if maltreated and nonmaltreated individuals with the same diagnostic labels are differentiated.

Longitudinal associations between types of childhood trauma and suicidal behavior among substance users: a cohort study

OBJECTIVES

We examined the longitudinal associations between different types and severities of childhood trauma and suicide attempts among illicit drug users.

METHODS

Data came from 2 prospective cohort studies of illicit drug users in Vancouver, Canada, in 2005 to 2010. We used recurrent event proportional means models to estimate adjusted and weighted associations between types and severities of childhood maltreatment and suicide attempts.

RESULTS

Of 1634 participants, 411 (25.2%) reported a history of suicidal behavior at baseline. Over 5 years, 80 (4.9%) participants reported 97 suicide attempts, a rate of 2.6 per 100 person-years. Severe to extreme levels of sexual abuse (adjusted hazard ratio [AHR] = 2.5; 95% confidence interval [CI] = 1.4, 4.4), physical abuse (AHR = 2.0; 95% CI = 1.1, 3.8), and emotional abuse (AHR = 3.5; 95% CI = 1.4, 8.7) predicted suicide attempts. Severe forms of physical and emotional neglect were not significantly associated with an increased risk of suicidal behavior.

CONCLUSIONS

Severe sexual, physical, and emotional childhood abuse confer substantial risk of repeated suicidal behavior in adulthood. Illicit drug users require intensive secondary suicide prevention efforts, particularly among those with a history of childhood trauma.

Hepatitis C virus in American Indian/Alaskan Native and Aboriginal peoples of North America

Liver diseases, such as hepatitis C virus (HCV), are “broken spirit” diseases. The prevalence of HCV infection for American Indian/Alaskan Native (AI/AN) in the United States and Canadian Aboriginals varies; nonetheless, incidence rates of newly diagnosed HCV infection are typically higher relative to non-indigenous people. For AI/AN and Aboriginal peoples risk factors for the diagnosis of HCV can reflect that of the general population: predominately male, a history of injection drug use, in midlife years, with a connection with urban centers. However, the face of the indigenous HCV infected individual is becoming increasingly female and younger compared to non-indigenous counterparts. Epidemiology studies indicate that more effective clearance of acute HCV infection can occur for select Aboriginal populations, a phenomenon which may be linked to unique immune characteristics. For individuals progressing to chronic HCV infection treatment outcomes are comparable to other racial cohorts. Disease progression, however, is propelled by elevated rates of co-morbidities including type 2 diabetes and alcohol use, along with human immunodeficiency virus (HIV) co-infection relative to non-indigenous patients. Historical and personal trauma has a major role in the participation of high risk behaviors and associated diseases. Although emerging treatments provide hope, combating HCV related morbidity and mortality will require interventions that address the etiology of broken spirit diseases.

Childhood sexual abuse and risk for initiating injection drug use: a prospective cohort study

OBJECTIVE

This study examined whether childhood sexual abuse predicts initiation of injection drug use in a prospective cohort of youth.

METHOD

From October 2005 to November 2010, data were collected from the At Risk Youth Study (ARYS), a prospective cohort study of street-involved youth in Vancouver, Canada. Inclusion criteria were age 14-26 years, no lifetime drug injection, and non-injection drug use in the month preceding enrollment. Participants were interviewed at baseline and semiannually thereafter. Cox regression was employed to identify risk factors for initiating injection.

RESULTS

Among 395 injection-naïve youth, 81 (20.5%) reported childhood sexual abuse. During a median follow-up of 15.9 months (total follow-up 606.6 person-years), 45 (11.4%) youth initiated injection drug use, resulting in an incidence density of 7.4 per 100 person-years. In univariate analyses, childhood sexual abuse was associated with increased risk of initiating injection (unadjusted hazard ratio [HR], 2.38; 95% confidence interval [CI], 1.29-4.38; p=0.006), an effect that persisted in multivariate analysis despite adjustment for gender, age, aboriginal ancestry and recent non-injection drug use (adjusted HR, 2.71; 95% CI, 1.42-5.20; p=0.003).

CONCLUSION

Childhood sexual abuse places drug users at risk for initiating injection. Addiction treatment programs should incorporate services for survivors of childhood maltreatment.

Dual HIV risk and vulnerabilities among women who use or inject drugs: no single prevention strategy is the answer

PURPOSE OF REVIEW

This article examines the dual HIV and sexually transmitted infection (STI) risk behaviors engaged in by women who use or inject drugs; the individual, social, and structural drivers of HIV and STI risk; prevention strategies; and the implications for multilevel, combined, sex-specific HIV prevention strategies.

RECENT FINDINGS

Women who use or inject drugs, especially female sex workers, are at dual risk for HIV, the hepatitic C virus (HCV), and other STIs. In countries with HIV prevalence higher than 20% among injecting drug users (IDUs), female IDUs have slightly higher HIV prevalence than male IDUs. Women who use or inject drugs face multilevel drivers that increase their vulnerabilities to HIV, HCV, and STIs. Despite advances in behavioral HIV prevention strategies for this population, most prevention studies have not sufficiently targeted dyadic, social, and structural levels. Few recent advances in biomedical HIV prevention have focused on women who use drugs and their unique needs.

SUMMARY

HIV prevention strategies and services need to address the unique and multilevel drivers that increase the vulnerabilities to HIV, HCV, and STIs among women who use drugs including those who engage in sex work. Scaling-up and improving access to multilevel and combined HIV prevention strategies for these women is central to combating the HIV epidemic.

Neurocognitive deficits in HIV-infected women and victims of childhood trauma

The study investigated the behavioral and brain effects of childhood trauma and human immunodeficiency virus (HIV) infection, both separately and in combination, and assessed potential interactions in women who were dually affected. Eighty-three HIV-positive and 47 matched HIV-negative South African women underwent neuromedical, neuropsychiatric, and neurocognitive assessments. Univariate tests of significance assessed if either HIV infection or childhood trauma, or the combination, had a significant effect on neurocognitive performance. The majority of women were Black (96%) and had an average age of 30 years. An analysis of covariance revealed significant HIV effects for the Hopkins Verbal Learning Test (HVLT) learning and delay trials (p < 0.01) and the Halstead Category Test (HCT) (p < 0.05). A significant trauma effect was seen on the HVLT delay trial (p < 0.05). The results provide evidence for neurocognitive dysfunction in memory and executive functions in HIV-infected women and memory disturbances in trauma exposed women.

Impact of childhood trauma on functionality and quality of life in HIV-infected women

BACKGROUND

While there are many published studies on HIV and functional limitations, there are few in the context of early abuse and its impact on functionality and Quality of Life (QoL) in HIV.

METHODS

The present study focused on HIV in the context of childhood trauma and its impact on functionality and Quality of Life (QoL) by evaluating 85 HIV-positive (48 with childhood trauma and 37 without) and 52 HIV-negative (21 with childhood trauma and 31 without) South African women infected with Clade C HIV. QoL was assessed using the Quality of Life Enjoyment and Satisfaction Questionnaire (Q-LES-Q), the Patient's Assessment of Own Functioning Inventory (PAOFI), the Activities of Daily Living (ADL) scale and the Sheehan Disability Scale (SDS). Furthermore, participants were assessed using the Center for Epidemiologic Studies Depression Scale (CES-D) and the Childhood Trauma Questionnaire (CTQ).

RESULTS

Subjects had a mean age of 30.1 years. After controlling for age, level of education and CES-D scores, analysis of covariance (ANCOVA) demonstrated significant individual effects of HIV status and childhood trauma on self-reported QoL. No significant interactional effects were evident. Functional limitation was, however, negatively correlated with CD4 lymphocyte count.

CONCLUSIONS

In assessing QoL in HIV-infected women, we were able to demonstrate the impact of childhood trauma on functional limitations in HIV.
