From trauma to transmission: exploring the intersection of adversity, substance use, and HIV risk in women’s life histories

BackgroundAt increased risk for poor health outcomes, physical and/or sexual violence, and onward transmission of HIV, women who use drugs and are living with HIV (WWUDHIV) are vulnerable and in need of services. Understanding the role of trauma across their life history may offer insights into HIV and drug use prevention and opportunities for intervention. We explored trauma and drug use among WWUDHIV in Dar es Salaam, Tanzania.MethodsWe conducted in-depth interviews with 30 WWUDHIV from January-March 2019. Interviewers used semi-structured interview guides and asked questions about the life history as related to drug use. Interviews were audio recorded, transcribed, translated, coded, and life histories charted. We utilized content analysis.ResultsParticipants described death of family members as traumatic catalysts for drug use. Sexual partners early in their life history were often the point of introduction to drugs and source of HIV acquisition. Death of partners was present across many life histories and was a traumatic event negatively influencing life trajectories, including start of sex work for survival or to support drug use. Sex work in-turn often led to traumatic events including sexual and/or physical violence. HIV diagnosis for many participants followed the start of drug use, frequently occurred during pregnancy or severe illness and was described by most participants as a trauma. Despite this, particularly during pregnancy, HIV diagnosis was a turning point for some participant’s desire to engage in drug use treatment. Traumatic events were often cumulative and regularly described as catalysts for poor mental health that could lead to new or increased drug use for coping.ConclusionsThese findings suggest trauma is common in the life history of WWUDHIV and has negative impacts on drug use and HIV vulnerability. Our life history charting highlights the cumulative and cyclical nature of trauma and drug use in this population. This study allows for better understanding of trauma, drug use, and HIV prevention, which offers opportunities for intervention among a group with limited access to services: during adolescence for orphaned youth, following the death of a child or partner, and when vulnerable women engage with the health system (HIV diagnosis, pregnancy, illness).

HIV risk perception, pre-exposure prophylaxis (PrEP) awareness, and PrEP initiation intention among women who use drugs

IntroductionWomen who use drugs (WWUD) are prime candidates for pre-exposure prophylaxis (PrEP) due to their elevated risk of acquiring HIV through biological, behavioral, and contextual factors. However, PrEP uptake among WWUD remains low. The relationship between unhealthy drug use and correlates of PrEP uptake in this vulnerable population is not well defined. The purpose of this study is to characterize the relationships between specific types and routes of drug use and several precursors of PrEP uptake among WWUD. MethodsThe study collected data via a computer-based survey from 233 women living in New York City and Philadelphia who participated in a study designed to develop and pilot a women-focused intervention for PrEP uptake. The sample of cisgender, HIV-negative women were not currently taking PrEP but considered PrEP eligible. This analysis is focused on women's HIV risk perception, PrEP awareness, PrEP initiation intention, and any use of the following drugs: barbiturates, benzodiazepines, crack cocaine, powder cocaine, hallucinogens, heroin, methamphetamines, and prescription opioids. ResultsWithin the three months prior to study enrollment, 63.1 % of participants reported any drug use; 42 % reported polydrug use; 19.8 % had injected drugs; 75 % reported getting high or drunk before sex; and 44 % had been enrolled in drug treatment. Of our total sample, 41.2 % perceived themselves at risk for HIV infection, 41.6 % were aware of PrEP prior to the study, and 62.7 % intended to initiate PrEP after they were informed. When compared to other PrEP-eligible women, women who reported prescription opioid use and polydrug use perceived themselves at higher risk for HIV infection and had higher intention to start PrEP. However, they and women who reported injecting drugs also reported lower awareness of PrEP. ConclusionThese findings have implications for increasing education about PrEP and the various modes of HIV exposure to support PrEP uptake in this vulnerable population.

Multilevel Factors Influencing Interruptions in PrEP Use Among Young Women in Siaya County, Kenya.

Young women in sub-Saharan Africa continue to be disproportionately at risk for HIV. Oral pre-exposure prophylaxis (PrEP) can reduce women's HIV risk when taken daily throughout their "seasons of risk". We used photovoice to describe community views on factors influencing interruptions in PrEP use among young cisgender women in Siaya County, Kenya. Through group discussions, young women taking PrEP and their social network members (female peers, male peers/partners, family, and community members) shared photographs and identified broad social-ecological causes of PrEP interruptions, including: (1) widespread misinformation about PrEP, (2) social pressures from religious communities, (3) health care staff recommendations to interrupt PrEP use, (4) partner rejection of PrEP, (5) changes in women's risk awareness, and (6) a personal desire to occasionally pause daily use. Collectively, participants identified strategies to address these challenges. These findings can inform future programs targeting the broader social-ecological influences on young women's persistent use of PrEP.

The impact of social violence on HIV risk for women in Colombia: A concurrent mixed methods study.

Gender, violence, and migration structurally impact health. The Venezuelan humanitarian crisis comprises the largest transnational migration in the history of the Americas. Colombia, a post-conflict country, is the primary recipient of Venezuelans. The Colombian context imposes high levels of violence on women across migration phases. There is little information on the relationship between violence and HIV risk in the region and how it impacts these groups. Evidence on how to approach the HIV response related to Venezuela's humanitarian crisis is lacking. Our study seeks to 1) understand how violence is associated with newly reported HIV/AIDS case rates for women in Colombian municipalities; and 2) describe how social violence impacts HIV risk, treatment, and prevention for Venezuelan migrant and refugee women undergoing transnational migration and resettlement in Colombia. We conducted a concurrent mixed-methods design. We used negative binomial models to explore associations between social violence proxied by Homicide Rates (HR) at the municipality level (n = 84). The also conducted 54 semi-structured interviews with Venezuelan migrant and refugee women and key informants in two Colombian cities to expand and describe contextual vulnerabilities to HIV risk, prevention and care related to violence. We found that newly reported HIV cases in women were 25% higher for every increase of 18 homicides per 100,000, after adjusting for covariates. Upon resettlement, participants cited armed actors' control, lack of government accountability, gender-based violence and stigmatization of HIV as sources of increased HIV risk for VMRW. These factors impose barriers to testing, treatment and care. Social violence in Colombian municipalities is associated with an increase in newly reported HIV/AIDS case rates in women. Violence hinders Venezuelan migrant and refugee women's access and engagement in available HIV prevention and treatment interventions.

How a 25-year-old periodic survey for lesbian, bisexual and queer women responded and adapted to gender diversity: a reflexive analysis

ABSTRACT Twenty-five years ago, the first Sydney Women and Sexual Health (SWASH) survey sought to generate knowledge about HIV risk for women in contact with Sydney’s gay and lesbian community. SWASH has gone on to become the longest running periodic survey of lesbian, bisexual and queer (LBQ) women’s health. It reflects LBQ women’s lives back to them and makes LBQ women knowable for Australian public policy. But, like all research, the social reality SWASH produces is a partial representation of the target population. As it entered its 12th iteration, it became clear the survey needed to change to better represent trans and gender diverse people’s lives. In this paper, we describe our process of first adding inclusive gender indicators, and then applying a gender diversity lens to all survey questions, data collection and reporting. We reflect on our motivations and fears, and where we can, the consequences on data of previous and new research design choices. Reflexive analysis such as ours, though still rare in quantitative research, promotes accountability to communities we research and the sectors who use the knowledge we produce.

COVID-19 Symptoms, Testing, and Test Positivity Among Trans Women in the San Francisco Bay Area in 2020-2021.

The novel coronavirus (COVID-19) is negatively impacting vulnerable and marginalized communities. Growing research among sexual and gender minority communities shows increased COVID-19 risk and burden due to underlying social structure factors, however, not as much is known about the impact on trans women. Our team gathered data on COVID-19 risk, self-reported prevalence, and testing behaviors as part of an ongoing study of trans women's HIV risk and partnerships to fill this gap in data. This is a secondary analysis of data from The Partners Study, a study of HIV risk and transmission among trans women and their sexual partners in the San Francisco Bay Area. We collected COVID-19-related data from 87 trans women from July 2020 to January 2021. Participants were asked whether they were tested for COVID-19, had symptoms, or tested positive for the virus between March 2020 to the time they were screened to participate for a survey interview. The majority of trans women did not report experiencing COVID-19 symptoms (85.05%, n=74/87) since March 2020. More than half had been tested for COVID-19 (68.9%, n=60/87). Overall, we found a COVID-19 prevalence of 8.33% (n=5/60) among those who received a COVID-19 test. The COVID-19 prevalence among trans women in our sample was higher than in other gender groups in San Francisco, suggesting that trans women may be disproportionately impacted by this disease. More research is needed to determine the impact of COVID-19 on trans women, and to develop strategies to increase testing and vaccinations among vulnerable communities preventing onward spread.

Missed Opportunities for HIV Prevention in Perinatal Care Settings in the United States.

Universal opt-out HIV screening in pregnancy is an essential intervention toward eliminating perinatal HIV transmission in the US. However, it fails to identify pregnant people who are HIV negative at the time of testing but are at ongoing risk for HIV acquisition. Those of us involved in caring for women living with HIV are acutely aware of the many diagnoses of HIV that might have been prevented if only a partner had been tested for HIV or preexposure prophylaxis (PrEP) had been offered to a patient. This perspective article will review current recommendations and evidence-based interventions to evaluate missed opportunities for HIV prevention in US perinatal care settings. We identified three barriers to implementation of HIV prevention strategies during pregnancy and breastfeeding: (1) HIV risk for women is underestimated and poorly defined in clinical practice; (2) Partner testing is challenging and implementation studies in the US are lacking; and (3) PrEP remains underutilized. In March 2020, the National Perinatal HIV Hotline convened a group of clinicians and researchers specializing in perinatal HIV care to a case-based discussion of missed opportunities in perinatal HIV prevention. From our review of the literature via PubMed search as well as expert opinions gathered in this discussion, we make recommendations for addressing these barriers.

Fertility and HIV risk in Africa

This paper examines the role of social and cultural norms regarding fertility in women's HIV risk in Sub-Saharan Africa. Fertility is highly valued in most African societies, and premarital fertility is often encouraged to facilitate marriage. This incentivizes unprotected premarital sex and escalates HIV risk. I build a rich lifecycle model linking women's decisions concerning sex, fertility and education to HIV infection and calibrate it to match Kenyan data. Quantitative results show that premarital fertility motives account for 13 percent of HIV prevalence among young Kenyan women and that a combination of fertility motives and contraception cost accounts for nearly one-third of this prevalence. Various policies are evaluated. While an HIV treatment subsidy would reduce HIV prevalence to the greatest extent, its effectiveness would be severely mitigated by increased risky sex.

HIV Pathogenesis in the Human Female Reproductive Tract.

Women remain disproportionately affected by the HIV/AIDS pandemic. The primary mechanism for HIV acquisition in women is sexual transmission, yet the immunobiological factors that contribute to HIV susceptibility remain poorly characterized. Here, we review current knowledge on HIV pathogenesis in women, focusing on infection and immune responses in the female reproductive tract (FRT). We describe recent findings on innate immune protection and HIV target cell distribution in the FRT. We also review multiple factors that modify susceptibility to infection, including sex hormones, microbiome, trauma, and how HIV risk changes during women's life cycle. Finally, we review current strategies for HIV prevention and identify barriers for research in HIV infection and pathogenesis in women. A complex network of interrelated biological and sociocultural factors contributes to HIV risk in women and impairs prevention and cure strategies. Understanding how HIV establishes infection in the FRT can provide clues to develop novel interventions to prevent HIV acquisition in women.

Responding to the ECHO trial results: modelling the potential impact of changing contraceptive method mix on HIV and reproductive health in South Africa.

IntroductionSome observational data suggest that the progestogen injectable contraceptive depot medroxyprogesterone acetate (DMPA) may increase a woman’s risk of HIV acquisition but a randomized clinical trial did not find a statistically significant increase in HIV risk for women using DMPA compared to two other methods. However, it could not rule out up to 30% increased HIV risk for DMPA users. We evaluate changes to contraceptive method mix in South Africa under different assumptions about the existence and strength of a possible undetected relationship between DMPA use and HIV risk.MethodsA mathematical model was developed to simulate the ongoing HIV epidemic and contraceptive method mix in South Africa to estimate how changes in method mix could impact HIV‐ and reproductive health‐related outcomes. We made different assumptions about the relationship between DMPA use and HIV risk, from no relationship to a 30% increase in HIV risk for women using DMPA. Scenario analyses were used to investigate the impact of switching away from DMPA predominance to new patterns of contraceptive use.ResultsIn South Africa, the HIV‐related benefits of reduced DMPA use could be as great as the harms of increased adverse reproductive health outcomes over 20 years, if DMPA did increase the risk of HIV acquisition by a relative hazard of infection of 1.1 or greater. A reduction in DMPA use among HIV‐positive women would have no benefit in terms of HIV infections, but would incur additional negative reproductive health outcomes. The most important driver of adverse reproductive health outcomes is the proportion of women who switch away from DMPA to no contraceptive method.ConclusionsIf there is any real increased HIV risk for DMPA users that has not been detected by the recent randomized trial, a reduction in DMPA use could reduce the ongoing number of new HIV infections. However, such a change would place more women at risk of adverse reproductive health effects. It is imperative that these effects are minimized by focusing on expanding access to safe, effective and acceptable alternative contraceptive methods for all women.

Examining Why Age-Disparate Relationships Influence Unsafe Sex Postpartum Among South African Women: Relationship Control and Physical Partner Violence as Explanatory Mechanisms.

HIV incidence rates in South Africa are extremely high, particularly postpartum. However, there is limited knowledge of women's HIV risk behavior postpartum. Women in age-disparate relationships may be less able to negotiate safe sex postpartum than women whose partners are similar ages because they have less relationship power. The study's purpose is to test whether being in an age-disparate relationship predicts postpartum unsafe sex and to explore relationship control and intimate partner violence (IPV) as explanatory mechanisms. Data are obtained from 516 HIV-negative participants who completed a survey during pregnancy and at 14 weeks postpartum as part of a longitudinal study in Durban. Age variables, relationship control, and IPV during pregnancy were included in a multivariate model predicting unsafe sex postpartum. We also assessed whether the hypothesized mediators explained the association between being in an age-disparate relationship and unsafe sex postpartum by using indirect effect analysis with bootstrapping. Women's mean age was 24.34 years (range = 18.03-45.36); the mean difference in ages in relationships was 3.19 years (range = -6.1 to 30.1). More than a quarter reported unsafe sex postpartum (27%). Age-disparate relationship, lower relationship control, and higher IPV were each longitudinally associated with unsafe sex. Relationship control, but not IPV, mediated the association between age-disparate relationship and unsafe sex (indirect effect [B] = 0.01, 95% confidence interval [CI] = [0.0002, 0.0283]). Age disparity, relationship control, and IPV all contributed to unsafe sex postpartum. Interventions that reduce the formation of age-disparate relationships and increase women's relationship power in pregnancy are needed to reduce women's HIV risk in the postpartum period.

HIV, progestins, genital epithelial barrier function, and the burden of objectivity†.

Contributions from a diverse set of scientific disciplines will be needed to help individuals make fully informed decisions regarding contraceptive choices least likely to promote HIV susceptibility. This commentary recaps contrasting interpretations of results from the Evidence for Contraceptive Options and HIV Outcomes (ECHO) Trial, a study that compared HIV risk in women using the progestin-only injectable contraceptive depot medroxyprogesterone acetate (DMPA) vs. two other contraceptive choices. It also summarizes results from basic and translational research that establish biological plausibility for earlier clinical studies that identified enhanced HIV susceptibility in women using DMPA.

HIV Infection in Attendees of Psychiatric Clinics in Harare, Zimbabwe; Prevalence, Associated Factors and HIV Care Uptake.

Determination of HIV prevalence among people with mental illness is necessary for developing integrated services for HIV and mental illness. This study determined HIV prevalence and uptake of HIV care among outpatients of psychiatric hospitals in Harare, Zimbabwe. HIV status was determined using open testing of 270 randomly selected consenting adult outpatients. HIV prevalence was 14.4% and the risk of acquiring HIV was similar to the general population of adults in Zimbabwe. Females were six times more likely to have HIV infection than males. Although a relatively high proportion of patients had been tested for HIV in the past (77.2%), fewer were recently tested (27.8%). Access to HIV care was high (94%) amongst patients previously diagnosed to be HIV positive. Tertiary mental health services should offer similar HIV care packages as other points of care and there is need for interventions that reduce the risk of HIV in women with mental disorders.

Three Long-Acting Reversible Contraceptives Did Not Differentially Affect Risk for HIV Acquisition

Observational studies in sub-Saharan Africa have suggested that intramuscular depot medroxyprogesterone (DMPA-IM) can increase women's risk for HIV

Developing Experimental Vignettes to Identify Gender Norms Associated With Transactional Sex for Adolescent Girls and Young Women in Central Uganda

PurposeTransactional sex or informal sexual exchange relationships increase adolescent girls' and young women's (AGYW) HIV and pregnancy risk in sub-Saharan Africa. These relationships are grounded in the shared expectation that men should provide financial support to their partners. We built a vignette experiment to assess whether gender norms influenced by expectations of provision help to explain how transactional sex increases AGYW's sexual and reproductive health risks. MethodsWe used mixed methods to develop a vignette experiment in Central Uganda with AGYW including 10 focus group discussions, 32 cognitive interviews, and a pilot survey experiment with 108 sexually active unmarried AGYW. Respondents were randomly assigned to one of the two manipulations for three vignettes. The vignettes examined whether the amount a man provided changed perceived social approval of men's authority in relationships, sexual decision-making power, or women having multiple partners. ResultsWe find that a higher level of male provision is associated with higher levels of perceived community approval for his sexual decision-making power (p < .001) and lower levels of perceived peer approval for AGYW's to seek a second partner (p < .05). We also find that higher levels of male provision are associated with respondent's own approval of male authority and sexual decision-making. ConclusionOur findings suggest that approval of men's sexual decision-making power increases when they provide more and that girls who seek a second partner find higher levels of social approval for this behavior when their primary partner provides less. Vignette experiments may be valuable for identifying social norms that put AGYW's sexual and reproductive health at risk.

The TRANScending Love Arts-Based Workshop to Address Self-Acceptance and Intersectional Stigma Among Transgender Women of Color in Toronto, Canada: Findings from a Qualitative Implementation Science Study.

Purpose: Transgender (trans) women of color's HIV vulnerabilities are shaped by social exclusion and intersectional stigma. There is a dearth of tailored HIV prevention interventions with trans women of color in Canada. The objective of the study was to explore trans women of color's HIV prevention priorities and to pilot test an intervention developed from these priorities.Methods: We conducted a qualitative implementation science study to develop HIV intervention strategies with trans women of color in Toronto, Canada. First, we conducted a focus group with trans women of color (n=8) to explore HIV prevention priorities. Second, we held a consultation with trans women of color community leaders (n=2). Findings informed the development of the TRANScending Love (T-Love) arts-based workshop that we pilot tested with three groups of trans women of color (n=18). Workshops were directly followed by focus groups to examine T-Love products and processes.Results: Focus group participants called for researchers to shift the focus away from trans women's bodies and HIV risks to address low self-acceptance produced by intersecting forms of stigma. The community leader consultation articulated the potential for strengths-focused arts-based approaches to address self-worth. T-Love participants described how workshops fostered self-acceptance and built connections between trans women of color.Conclusions: Findings demonstrate the feasibility and acceptability of an arts-based strategy with trans women of color to elicit group-based sharing of journeys to self-acceptance, fostering feelings of solidarity and connection. Providing opportunities for dialogue and reflection about individual and collective strengths may reduce internalized stigma among trans women of color.

Inflammatory Cytokine Profiles of Semen Influence Cytokine Responses of Cervicovaginal Epithelial Cells.

Genital inflammatory cytokine responses increase HIV risk. Since male partner semen is a complex mixture of immune-modulatory prostaglandins and cytokines, we hypothesized that exposure to semen may influence genital inflammation in women. Here, we investigated cytokine response kinetics of cervical cells following stimulation with seminal plasma from HIV-negative and HIV-positive men characterized as having low or high concentrations of inflammatory cytokines. Irrespective of the HIV status or semen cytokine profile, in vitro stimulation of cervical cells with seminal plasma resulted in significantly elevated concentrations of secreted IL-6, IL-8, TNF-β, MCP-1, GM-CSF, and VEGF within 8 h of stimulation, which tended to decline by 24 h, although this was only significant for TNF-β. Consistent with this, cervical cells responded to seminal plasma with increases in IL-8 and IL-1β mRNA expression of 10-fold. These findings suggest that the impact of semen on local female genital cytokines is likely transient. Although these findings suggest that the impact of semen on local female genital cytokines may not be sustained long-term, this heightened genital inflammation may have implications for HIV risk in women.

HIV Risk Among Adolescent Girls and Young Women in Age-Disparate Partnerships: Evidence From KwaZulu-Natal, South Africa.

Evidence on the role of age-disparate partnerships in high HIV-infection rates among young women in sub-Saharan Africa remains inconclusive. This study examined the HIV-infection risk associated with age-disparate partnerships among 15- to 24-year-old women in a hyperendemic setting in South Africa. Face-to-face questionnaire, and laboratory HIV and viral load data were collected during 2014-2015 among a representative sample (15-49 years old) in KwaZulu-Natal. The association between age-disparate partnerships (age difference ≥5 years) and HIV status among 15- to 24-year-old women (N = 1459) was assessed using multiple logistic regression analyses. Data from the male sample on all on-going partnerships (N = 1229) involving 15- to 24-year-old women were used to assess whether young women's age-disparate male partners were more likely to have a viral load ≥1000 copies per milliliter, a marker of HIV-infection risk. Women reporting an age disparity in any of their 3 most recent partnerships were more likely to test HIV positive compared to women with only age-similar partners [adjusted odds ratio (aOR): 1.58, 95% confidence interval (CI): 1.20 to 2.09, P < 0.01]. Among partnerships men reported with 15- to 24-year-old women, the age-disparate male partners were more likely to be HIV positive and have a viral load ≥1000 copies per milliliter (aOR: 2.05, 95% CI: 1.30 to 3.24, P < 0.01) compared with age-similar partners. Results were similar for each category of age disparity: partners 5-9 years older (aOR: 2.01, 95% CI: 1.18 to 3.43, P = 0.010) and those ≥10 years older (aOR: 2.17, 95% CI: 1.01-4.66, P = 0.048). Results indicate that age-disparate partnerships increase young women's HIV risk, although conclusive evidence was not ascertained. Interventions addressing risk from age-disparate sexual partnering, including expanding antiretroviral treatment among older partners, may help to reduce HIV incidence among young women.

No Access to Services: The Struggle of Injection Drug Using Women in Abusive Relationships

Women who experience violence and are at risk for HIV/AIDS are a multiply marginalized population which the majority of service providers ignore or feel they do not have the resources to deal with. Furthermore, while the Canadian government issues reports on violence against women, it does not provide an analysis of the intersection between violence HIV/AIDS. Women who are at risk for HIV due to injection drug use are particularly vulnerable when in a violent relationship; most women’s shelters have zero tolerance policies for substance use leaving these women isolated. By examining how substance use increases HIV risk for women who experience violence, the high risk behaviors associated with violence, and the high risk behaviors associated with substance use, multiply marginalized women’s needs become clearer. Service providers for multiply marginalized women must always consider the ramifications of their policies, as well as the ideologies that their policies are based on so that they can effectively help their target population. To address the needs of multiply marginalized women, drastic changes need to be made to the current shelter system: shelters need to examine their ideological foundation and analyze what stigmas their current policies support. Coordinated efforts are needed between multiple service providers to address the challenges that these often forgotten women face.

Community narratives about women and HIV risk in 21 high-burden communities in Zambia and South Africa.

Public health researchers repeatedly represent women as a group vulnerable to ill health. This has been particularly true in the field of HIV research, where women are disproportionately affected by HIV in terms of disease burden and the social effects of the epidemic. Although women have been the focus of many prevention and treatment programs, structural barriers to implementation of these targeted programs persist. In this article we explore how high HIV-burden communities in South Africa and Zambia engage with the concepts of “woman” and “HIV risk”. The data are drawn from participatory storytelling activities completed with 604 participants across 78 group discussions between December 2012 and May 2013. During discussions we found that participants made use of the core archetypal caricatures of “goodness,” “badness,” and “vulnerability” when describing women’s HIV risk. Community members shifted between these categories in their characterizations of women, as they acknowledged the multiple roles women play, internalized different stories about women, and sometimes shifted register in the same stories. Findings suggest that health implementers, in consultation with community members, should consider the multiple positions women occupy and how this impacts the wider community’s understandings of women and “risk”. This approach of taking on board community understandings of the complexity of HIV risk can inform the design and implementation of HIV prevention and care programs by rendering programs more focused and in-line with community needs.
