Multilevel strategies to end HIV for young couples in Cape Town: Study protocol for a cluster randomized trial.

This protocol presents a multilevel cluster randomized study in 24 communities in Cape Town, South Africa. The study comprises four specific aims. Aim 1, conducted during the formative phase, was to modify the original Couples Health CoOp (CHC) intervention to include antiretroviral therapy/pre-exposure prophylaxis (ART/PrEP), called the Couples Health CoOp Plus (CHC+), with review from our Community Collaborative Board and a Peer Advisory Board. Aim 1 has been completed for staging the trial. Aim 2 is to evaluate the impact of a stigma awareness and education workshop on community members' attitudes and behaviors toward young women and men who use AODs and people in their community seeking HIV services (testing/ART/PrEP) and other health services in their local clinics. Aim 3 is to test the efficacy of the CHC+ to increase both partners' PrEP/ART initiation and adherence (at 3 and 6 months) and to reduce alcohol and other drug use, sexual risk and gender-based violence, and to enhance positive gender norms and communication relative to HIV testing services (n = 480 couples). Aim 4 seeks to examine through mixed methods the interaction of the stigma awareness workshop and the CHC+ on increased PrEP and ART initiation, retention, and adherence among young women and their primary partners. Ongoing collaborations with community peer leaders and local outreach staff from these communities are essential for reaching the project's aims. Additionally, a manualized field protocol with regular training, fidelity checks, and quality assurance are critical components of this multilevel community trial for successful ongoing data collection.

Outcomes of substance use and sexual power among adolescent girls and young women in Cape Town: Implications for structural and cultural differences.

Adolescent girls and young women (AGYW) in South Africa experience contextual barriers to HIV risk reduction including incomplete schooling, unintended pregnancy, substance use, and gender-based violence. A cluster randomised trial in Cape Town allocated 24 Black and Coloured communities to a gender-focused HIV risk-reduction intervention or HIV testing, with 500 AGYW total enrolled. We evaluated intervention efficacy by comparing mean differences overall, by community population group (Black and Coloured) and among those with structural barriers based on neighbourhood, education, and employment (n = 406). Both arms reported reductions in alcohol, cannabis, and condomless sex, with no intervention efficacy overall. Among AGYW with barriers, intervention participants reported fewer days of methamphetamine use at 6 months (t(210) = 2·08, p = ·04). In population group analysis, we found intervention effects on alcohol and sexual communication. Intervention participants in Black communities had fewer days of alcohol use at 12 months (t(136) = 2·10, p = ·04). Sexual discussion (t(147) = -2·47, p = ·02) and condom negotiation (t(146) = -2·51, p = ·01) increased for intervention participants at 12 months in Coloured communities. Gender-focused interventions must address population group differences and intersecting barriers to decrease substance use and increase education, skills, and sexual health protection.

Alcohol, drug use, and sexual risk among young African American women in North Carolina: Is educational attainment protective?

Previous research shows that educational attainment is a protective factor for substance use and sexual risk among adolescents and young adults. Evidence also shows that this relationship may differ by race/ethnicity and gender. This study aimed to elucidate the relationship between educational attainment, substance use and sexual risk among African American women in emerging adulthood. This study uses cross-sectional data from 646 African American women (aged 18 to 25) enrolled in a randomized trial of a behavioral HIV risk-reduction intervention. At enrollment, participants completed a risk behavior assessment via audio-computer assisted self-interview and provided a urine sample for drug screening. Bivariate logistic regression analyses were conducted to examine substance use and sexual risk factors associated with educational attainment: completing some college or more vs. completing high school or less). Participants who completed some college or more (52%) were more likely to report heavy alcohol use (four or more drinks in one day) in the past 30 days (OR=1.48; p=0.014) and more likely to report alcohol or other drug use just before or during last sex (OR=1.43; p=0.026) compared with participants who completed high school or less. Completing some college or more was protective for having a positive urine screen for cocaine (OR=0.43; p=0.018) and reporting condomless sex at last sex (OR=0.71; p=0.041). Differences in positive marijuana screens, reporting a previous STI, or reporting their partner used alcohol or other drugs at last sex were not statistically significant. The findings reveal notable differences in the magnitude and direction of associations between educational attainment and substance use and sexual risk. Although educational attainment is subject to change because of the frequent pursuit of education during emerging adulthood, the findings may have important implications for tailoring HIV risk-reduction interventions to key populations, such as African American women.

Stigma in the health clinic and implications for PrEP access and use by adolescent girls and young women: conflicting perspectives in South Africa.

BACKGROUND: Globally, an urgent need exists to expand access to HIV prevention among adolescent girls and young women (AGYW), but the need is particularly acute in sub-Saharan Africa. Oral pre-exposure prophylaxis (PrEP) offers an effective HIV prevention method. In many countries, however, accessing PrEP necessitates that AGYW visit their local health clinic, where they may face access challenges. Some countries have implemented youth-friendly services to reduce certain challenges in local health clinics, but barriers to access persist, including clinic stigma. However, evidence of clinic stigma toward AGYW, particularly with respect to PrEP service delivery, is still limited. This mixed methods study explores stigma toward AGYW seeking clinic services, in particular PrEP, from the perspective of both clinic staff (clinical and nonclinical) and AGYW who seek services at clinic sites in Tshwane province, South Africa. METHODS: Six focus group discussions were conducted with AGYW (43 total participants) and four with clinic staff (42 total participants) and triangulated with survey data with AGYW (n = 449) and clinic staff (n = 130). Thematic analysis was applied to the qualitative data and descriptive statistics were conducted with the survey data. RESULTS: Four common themes emerged across the qualitative and quantitative data and with both AGYW and clinic staff, although with varying degrees of resonance between these two groups. These themes included (1) clinic manifestations of stigma toward AGYW, (2) concerns about providing PrEP services for AGYW, (3) healthcare providers' identity as mothers, and (4) privacy and breaches of confidentiality. An additional theme identified mainly in the AGYW data pertained to stigma and access to healthcare. CONCLUSION: Evidence is needed to inform strategies for addressing clinic stigma toward AGYW, with the goal of removing barriers to PrEP services for this group. While awareness has increased and progress has been achieved around the provision of comprehensive, youth-friendly sexual and reproductive health services, these programs need to be adapted for the specific concerns of young people seeking PrEP services. Our findings point to the four key areas noted above where programs seeking to address stigma toward AGYW in clinics can tailor their programming.

Antiretroviral Therapy (ART) Adherence and Prenatal Alcohol Use among Women Who Are Pregnant with HIV in South Africa.

This brief report emphasizes the need to focus on women with HIV who are pregnant who use alcohol or other drugs. A recently completed implementation science study tested a gender-focused behavioral intervention, the Women's Health CoOp (WHC), to improve antiretroviral therapy (ART) adherence and reduce alcohol use among women with HIV. The study identified 33 participants who had a positive pregnancy test result at the baseline assessment, of whom five participants remained pregnant during the 6-month duration of the study. Of the 33 pregnant participants at the baseline assessment, 55% reported past-month alcohol use, with 27% reporting a history of physical abuse and 12% reporting a history of sexual abuse. The five women who remained pregnant at 6 months showed improved ART adherence and reduced prenatal alcohol use. The gender-focused WHC intervention shows promise as a cost-effective, sustainable, behavioral intervention to address these intersecting syndemic issues. Future research should focus on identifying the needs of women with HIV who are pregnant who use alcohol or other drugs and developing tailored evidence-based behavioral interventions such as the WHC for preventing FASD in addition to improving ART adherence in this key population of women and reducing the economic burden on society.

Outcomes of Implementing in the Real World the Women's Health CoOp Intervention in Cape Town, South Africa.

Women in South Africa living with HIV who use alcohol may not adhere to ART, affecting the country's 90-90-90 targets. The Women's Health CoOp (WHC), a woman-focused HIV intervention, has shown efficacy in numerous trials with key populations of women in South Africa who use alcohol and drugs. In a hybrid implementation effectiveness study, the WHC was implemented in usual care clinics by healthcare providers in a modified stepped-wedge design. We present the outcomes of alcohol use and ART adherence with 480 women, with a 95% 6-month follow-up rate across 4 implementation cycles. Compared with the first cycle, women in the fourth cycle were significantly less likely (OR = 0.10 [95% CI 0.04, 0.24]) to report alcohol use disorder risk and were 4 times more likely (OR = 4.16 [95% CI 1.05, 16.51]) to report ART adherence at 6-month follow-up. Overall, acceptability and satisfaction were extremely high. The WHC intervention was successful in reaching key populations of women to reduce alcohol use and increase ART adherence, which is essential for South Africa to reach the 90-90-90 goals.

Adolescent female school dropouts who use drugs and engage in risky sex: effects of a brief pilot intervention in Cape Town, South Africa.

Female adolescents from socioeconomically underserved communities in Cape Town, South Africa, who have dropped out of school, use substances, and engage in risky sex behaviour are at risk of HIV. Tailored gender-focused HIV behavioural interventions for this key population are needed to mitigate these risk factors. A pilot trial of a woman-focused risk-reduction intervention for adolescents was conducted (N = 100), with a one-month follow-up appointment. Participants in the intervention group attended two group workshops. Data were examined for significant differences within and between the groups. At baseline, 94% of participants tested positive for cannabis, 17% were HIV-positive and 11% were pregnant. Ninety-two participants returned for 1-month follow-up. At follow-up, the proportion who tested positive for cannabis use decreased significantly in both the intervention (p = 0.07) and control groups (p = 0.04). Impaired sex with any partner (p = 0.02), or with main partner (p = 0.06) decreased among the intervention group. Impaired sex with a main partner was less likely in the intervention group (p = 0.07) in the regression model. In conclusion, findings indicate a need for HIV prevention interventions among out-of-school female adolescents. Intervention acceptability was high, and there were some decreases in sexual risk behaviour among intervention participants which is promising. Future intervention research with this key population involving larger sample sizes and longer follow-up periods will help to determine intervention efficacy.

Addressing the nexus of risk: Biobehavioral outcomes from a cluster randomized trial of the Women's Health CoOp Plus in Pretoria, South Africa.

BACKGROUND: HIV prevalence has increased among South African women who use alcohol and other drugs (AOD). However, HIV prevention and treatment efforts have not focused on this population. This study presents the efficacy of the Women's Health CoOp Plus (WHC+) in a cluster-randomized trial to reduce AOD use, gender-based violence, and sexual risk and to increase linkage to HIV care among women who use AODs, compared with HIV counseling and testing alone. METHODS: Black African women (N = 641) were recruited from 14 geographic clusters in Pretoria, South Africa, and underwent either an evidence-based gender-focused HIV prevention intervention that included HIV counseling and testing (WHC+) or HIV counseling and testing alone. Participants were assessed at baseline, 6-months, and 12-months post enrollment. RESULTS: At 6-month follow-up, the WHC+ arm (vs. HCT) reported more condom use with a main partner and sexual negotiation, less physical and sexual abuse by a boyfriend, and less frequent heavy drinking (ps < 0.05). At 12-month follow-up, the WHC+ arm reported less emotional abuse (p < 0.05). Among a subsample of women, the WHC+ arm was significantly more likely to have a non-detectable viral load (measured by dried blood spots; p = 0.01). CONCLUSION: The findings demonstrate the WHC+'s efficacy to reduce HIV risk among women who use AODs in South Africa. Substance abuse rehabilitation centers and health centers that serve women may be ideal settings to address issues of gender-based violence and sexual risk as women engage in substance use treatment, HIV testing, or HIV care.

Aggressive behaviour among drug-using women from Cape Town, South Africa: ethnicity, heavy alcohol use, methamphetamine and intimate partner violence.

BACKGROUND: Women have generally been found to be the victims of violence, but scant attention has been paid to the characteristics of women who perpetrate aggression and violence. In South Africa, violence is a prevalent societal issue, especially in the Western Cape. METHOD: This study aimed at identifying factors that were associated with aggression among a sample of 720 substance-using women. We conducted multivariate logistic regression to identify factors that are significantly associated with these behaviours. RESULTS: Ethnicity (Wald Χ2 = 17.07(2), p < 0.01) and heavy drinking (Wald Χ2 = 6.60 (2), p = 0.01) were significantly related to verbal aggression, methamphetamine use was significantly related to physical (Wald Χ2 = 2.73 (2), p = 0.01) and weapon aggression (Wald Χ2 = 7.94 (2), p < 0.01) and intimate partner violence was significantly related to verbal (Wald Χ2 = 12.43 (2), p < 0.01) and physical aggression (Wald Χ2 = 25.92 (2), p < 0.01). CONCLUSIONS: The findings show high levels of aggression among this sample, and highlight the need for interventions that address methamphetamine, heavy drinking and intimate partner violence among vulnerable substance-using women.

Efficacy of the Young Women's CoOp: An HIV Risk-Reduction Intervention for Substance-Using African-American Female Adolescents in the South.

HIV/sexually transmitted infection (STI) risk-reduction interventions are needed to address the complex risk behaviors among African-American female adolescents in disadvantaged communities in North Carolina. In a two-group randomized trial, we reached 237 sexually active, substance-using African-American female adolescents, to test a risk-reduction intervention, the Young Women's CoOp (YWC), relative to a nutrition control. In efficacy analyses adjusting for baseline condom use, at three-month follow-up participants in the YWC were significantly less likely to report sex without a condom at last sex relative to control. There were mixed findings for within-group differences over follow-up, underscoring the challenges for intervening with substance-using female youths.

Seek, Test and Disclose: knowledge of HIV testing and serostatus among high-risk couples in a South African township.

OBJECTIVES: HIV testing and disclosure of results to partners is an important strategy in HIV prevention but is under-researched within heterosexual partnerships. To address this gap, we describe patterns of HIV testing, discrepancies between beliefs and biologically confirmed HIV status of each partner, and characteristics of mutually correct knowledge of HIV status among heterosexual couples in a high-prevalence community. METHODS: The study recruited 290 high-risk heterosexual couples in stable relationships from a township in Cape Town, South Africa. Male patrons of shebeens (drinking establishments) were approached to participate with their main partner in an intervention designed to reduce substance use, violence and unsafe sex. All participants were tested for HIV at baseline and asked about their partner's past HIV testing and current status. Using the couple as the unit of analysis, we conducted logistic regression to identify partnership and individual characteristics associated with having mutually correct knowledge of partner's HIV status. RESULTS: Half (52%) of women and 41% of men correctly knew whether their partner had ever been tested for HIV. 38% of women, 28% of men and in 17% of couples, both members reported mutually correct knowledge of their partner's HIV status. Correlates of correct knowledge included married/cohabitating (aOR 2.69, 95% CI 1.35 to 5.40), both partners HIV-negative (aOR 3.32 (1.38 to 8.00)), women's acceptance of traditional gender roles (aOR 1.17 (1.01 to 1.40)) and men's relationship satisfaction (aOR 2.22 (1.01 to 4.44)). CONCLUSIONS: Findings highlight the need to improve HIV testing uptake among men and to improve HIV disclosure among women in heterosexual partnerships.

Gang membership and marijuana use among African American female adolescents in North Carolina.

The southeastern US sustains the highest high school dropout rates, and gangs persist in underserved communities. African American female adolescents who drop out of school and are gang members are at substantial risk of exposure to severe violence, physical abuse, and sexual exploitation. In this study of 237 female African American adolescents 16-19 years of age from North Carolina who dropped out or considered dropping out, 11% were current or past gang members. Adolescents who reported gang membership began smoking marijuana at a mean age of 13, whereas those who reported no gang membership began at a mean age of 15 years (P<0.001). The mean ages of first alcohol use were 14 years and 15 years for gang members and non-gang members, respectively (P=0.04). Problem alcohol use was high in both groups: 40% and 65% for non-gang and gang members, respectively (P=0.02). Controlling for frequent marijuana use and problem alcohol use, adolescents who reported gang membership were more likely than non-gang members to experience sexual abuse (odds ratio [OR] =2.60, 95% confidence interval [CI] [1.06, 6.40]), experience physical abuse (OR =7.33, 95% CI [2.90, 18.5]), report emotional abuse from their main partner (OR =3.55, 95% CI [1.44, 8.72]), run away from home (OR =4.65, 95% CI [1.90, 11.4]), get arrested (OR =2.61, 95% CI [1.05, 6.47]), and report violence in their neighborhood including murder (OR =3.27, 95% CI [1.35, 7.96]) and fights with weapons (OR =3.06, 95% CI [1.15, 8.11]). Gang members were less likely to receive emotional support (OR =0.89, 95% CI [0.81, 0.97]). These findings reinforce the urgent need to reach young African American women in disadvantaged communities affiliated with gangs to address the complexity of context and interconnected risk behaviors.

Relationship power, communication, and violence among couples: results of a cluster-randomized HIV prevention study in a South African township.

BACKGROUND: Inequitable gender-based power in relationships and intimate partner violence contribute to persistently high rates of HIV infection among South African women. We examined the effects of two group-based HIV prevention interventions that engaged men and their female partners together in a couples intervention (Couples Health CoOp [CHC]) and a gender-separate intervention (Men's Health CoOp/Women's Health CoOp [MHC/WHC]) on women's reports of power, communication, and conflict in relationships. METHODS: The cluster-randomized field experiment included heterosexual couples from a high-density South African township in which neighborhoods were randomized to one of the intervention arms or a control arm that received the WHC only. Participants completed in-person study visits at baseline and 6-month follow-up. We examined group differences using one-way analysis of variance and multivariable regression models. RESULTS: Of the 290 couples enrolled, 255 women remained in the same partnership over 6 months. Following the intervention, women in the CHC arm compared with those in the WHC arm were more likely to report an increase in relationship control (ß=0.92, 95% confidence interval [CI]: 0.02, 1.83, P=0.045) and gender norms supporting female autonomy in relationships (ß=0.99, 95% CI: 0.07, 1.91, P=0.035). Women in the MHC/WHC arm were more likely to report increases in relationship equity, relative to those in the CHC arm, and had a higher odds of reporting no victimization during the previous 3 months (MHC/WHC vs WHC: odds ratio =3.05, 95% CI: 1.55, 6.0, P=0.001; CHC vs MHC/WHC: odds ratio =0.38, 95% CI: 0.20, 0.74, P=0.004). CONCLUSION: Male partner engagement in either the gender-separate or couples-based interventions led to modest improvements in gender power, adoption of more egalitarian gender norms, and reductions in relationship conflict for females. The aspects of relationship power that improved, however, varied between the couples and gender-separate conditions, highlighting the need for further attention to development of both gender-separate and couples interventions.

Correlates of lifetime trauma exposure among pregnant women from Cape Town, South Africa.

A cross-sectional survey of 298 pregnant women from Cape Town, South Africa was conducted to examine socio-demographic, reproductive health, mental health, and relationship correlates of lifetime trauma exposure and whether these correlates vary as a function of age. Overall, 19.8% of participants reported trauma exposure. We found similarities and differences in correlates of trauma exposure among women in emerging adulthood and older women. Prior termination of pregnancy was associated with trauma exposure in both age groups. Difficulties in resolving arguments, lifetime substance use, and a prior sexually transmitted infection were associated with trauma exposure among women in emerging adulthood. In contrast, depression and awareness of substance abuse treatment programmes were associated with trauma exposure among older women. These findings highlight the need for interventions that prevent and treat trauma exposure among vulnerable women. Such interventions should be tailored to address the correlates of trauma exposure in each age group.

The biobehavioral Women's Health CoOp in Pretoria, South Africa: study protocol for a cluster-randomized design.

BACKGROUND: South Africa has 6.4 million adults over the age of 15 living with HIV. Gender inequality issues continue to drive the HIV epidemic in South Africa, where Black African women bear the greatest HIV burden. Limited access to services; little capacity to negotiate sex and condom use; and other legal, social, and economic inequities make women highly vulnerable to HIV infection. Behavioral interventions have been shown to decrease risk behaviors, but they have been less successful in reducing HIV incidence. Conversely, biomedical prevention strategies have proven to be successful in reducing HIV incidence, but require behavioral interventions to increase uptake and adherence. Consequently, there is a need for integrated approaches that combine biomedical and behavioral interventions. Effective combination prevention efforts should comprise biomedical, behavioral, and structural programming proven in randomized trials that focuses on the driving forces and key populations at higher risk of HIV infection and transmission. METHODS/DESIGN: This prospective, geographically clustered randomized field experiment is enrolling participants into two arms: a control arm that receives standard HIV testing and referral for treatment; and an intervention arm that receives an evidence-based, woman-focused behavioral intervention that emphasizes risk reduction and retention, the Women's Health CoOp. We divided the city of Pretoria into 14 mutually exclusive geographic zones and randomized these zones into either the control arm or the intervention arm. Outreach workers are recruiting drug-using women from each zone. At baseline, eligible participants complete a questionnaire and biological testing for HIV, recent drug use, and pregnancy. Follow-up interviews are completed at 6 and 12 months. DISCUSSION: The biobehavioral intervention in this study merges an efficacious behavioral HIV prevention intervention for women with biomedical prevention through HIV treatment as prevention using a Seek, Test, Treat and Retain strategy. This combination biobehavioral intervention is designed to (1) improve the quality of life and reduce HIV infectiousness among women who are HIV positive, and (2) reduce HIV risk behaviors among women regardless of their HIV status. If efficacious, this intervention could help control the HIV epidemic in South Africa. TRIAL REGISTRATION: Trial registration no: NCT01497405.

Perceived need for substance use treatment among young women from disadvantaged communities in Cape Town, South Africa.

BACKGROUND: Initiation of treatment for substance use disorders is low among young women from disadvantaged communities in Cape Town, South Africa. Yet little is known about the factors that influence perceived need for treatment (a determinant of treatment entry) within this population. METHODS: Baseline data on 720 young, drug-using women, collected as part of a randomized field experiment were analyzed to identify predisposing, enabling and health need factors associated with perceived need for treatment. RESULTS: Overall, 46.0% of our sample perceived a need for treatment. Of these participants, 92.4% wanted treatment for their substance use problems but only 50.1% knew where to access services. In multivariable logistic regression analyses, we found significant main effects for ethnicity (AOR = 1.54, 95% CI = 1.05-1.65), income (AOR = 0.96, 95% CI = 0.93-0.99), anxiety (AOR = 1.22, 95% CI = 1.05-1.45), and not having family members with drug problems (AOR = 1.45, 95% CI = 1.05-2.04) on perceived need for treatment. When the sample was stratified by methamphetamine use, income (AOR = 0.87, 95% CI = 0.79-0.96), awareness of treatment services (AOR =1.84, 95% CI = 1.03-3.27), anxiety (AOR =1.41, 95% CI = 1.06-1.87) and physical health status (AOR = 6.29, 95% CI = 1.56-25.64) were significantly associated with perceived need for treatment among those who were methamphetamine-negative. No variables were significantly associated with perceived need for treatment among participants who were methamphetamine-positive. CONCLUSIONS: A sizeable proportion of young women who could benefit from substance use treatment do not believe they need treatment, highlighting the need for interventions that enhance perceived need for treatment in this population. Findings also show that interventions that link women who perceive a need for treatment to service providers are needed. Such interventions should address barriers that limit young women's use of services for substance use disorders.

Contextualizing gender differences and methamphetamine use with HIV prevalence within a South African community.

BACKGROUND: This study was conducted in a large Black African township outside of Cape Town, South Africa, where HIV infection has been endemic at extremely high levels for years. Problems associated with high HIV prevalence are compounded by gender inequality and high rates of gender-based violence exacerbated by heavy alcohol use and increasing methamphetamine use. METHODS: Informal drinking establishments (known as shebeens) were geocoded and mapped. Based on visual examination, we identified 36 neighbourhoods, each of which contained between three to seven drinking venues clustered together. Neighbourhoods were separated from each other by at least 200m. We randomly selected 30 of the 36 neighbourhoods. Outreach workers screened males in shebeens and screened their female partners. This analysis includes 580 study participants recruited from 30 neighbourhoods between 2010 and 2012. All participants completed a baseline questionnaire that included individual-level, couple-level, and neighbourhood-level measures of alcohol and other drug use, HIV infection, and HIV risk behaviours. Multilevel fixed effects regression analyses stratified by gender were conducted to examine correlates of HIV infection. RESULTS: Women were twice as likely as men to be HIV infected, yet they reported fewer sex partners. Neighbourhood prevalence of HIV was correlated with greater likelihood of HIV infection among women, but not men. Neighbourhood methamphetamine use was marginally associated with HIV among women but not among men. At the individual level, heavy alcohol use was marginally associated with HIV infection among men but not among women. Having an HIV positive partner was the strongest correlate of being HIV positive among both men and women. CONCLUSION: Findings from this study underscore the need for policy makers to direct scarce resources to the communities, places within communities, and populations, especially vulnerable women, where the impact on HIV prevention and onward transmission will be greatest.

Ethnic differences in alcohol and drug use and related sexual risks for HIV among vulnerable women in Cape Town, South Africa: implications for interventions.

BACKGROUND: Alcohol and other drug (AOD) use among poor Black African and Coloured women in South Africa compounds their sexual risk for HIV. Given South Africa's history of ethnic disparities, ethnic differences in sex risk profiles may exist that should be taken into account when planning HIV risk reduction interventions. This paper aims to describe ethnic differences in AOD use and AOD-related sexual risks for HIV among vulnerable women from Cape Town, South Africa. METHOD: Cross-sectional data on 720 AOD-using women (324 Black African; 396 Coloured) recruited from poor communities in Cape Town were examined for ethnic differences in AOD use and AOD-related sexual risk behavior. RESULTS: Ethnic differences in patterns of AOD use were found; with self-reported drug problems, heavy episodic drinking and methamphetamine use being most prevalent among Coloured women and cannabis use being most likely among Black African women. However, more than half of Black African women reported drug-related problems and more than a third tested positive for recent methamphetamine use. More than a third of women reported being AOD-impaired and having unprotected sex during their last sexual encounter. Coloured women had four-fold greater odds of reporting that their last sexual episode was AOD-impaired and unprotected than Black African women. In addition, close to one in two women reported that their sexual partner was AOD-impaired at last sex, with Coloured women having three-fold greater odds of reporting that their partner was AOD-impaired at last sex than Black African women. CONCLUSIONS: Findings support the need to develop and test AOD risk reduction interventions for women from both ethnic groups. In addition, findings point to the need for tailored interventions that target the distinct profiles of AOD use and AOD-related sex risks for HIV among Black African and Coloured women.

Double jeopardy--drug and sex risks among Russian women who inject drugs: initial feasibility and efficacy results of a small randomized controlled trial.

BACKGROUND: With HIV prevalence estimated at 20% among female injecting drug users (IDUs) in St. Petersburg, Russia, there is a critical need to address the HIV risks of this at-risk population. This study characterized HIV risks associated with injecting drug use and sex behaviors and assessed the initial feasibility and efficacy of an adapted Woman-Focused intervention, the Women's CoOp, relative to a Nutrition control to reduce HIV risk behaviors among female IDUs in an inpatient detoxification drug treatment setting. METHOD: Women (N = 100) were randomized into one of two one-hour long intervention conditions--the Woman-Focused intervention (n = 51) or a time and attention-matched Nutrition control condition (n = 49). RESULTS: The results showed that 57% of the participants had been told that they were HIV-positive. At 3-month follow-up, both groups showed reduced levels of injecting frequency. However, participants in the Woman-Focused intervention reported, on average, a lower frequency of partner impairment at last sex act and a lower average number of unprotected vaginal sex acts with their main sex partner than the Nutrition condition. CONCLUSION: The findings suggest that improvements in sexual risk reduction are possible for these at-risk women and that more comprehensive treatment is needed to address HIV and drug risks in this vulnerable population.

The Relationship of Alcohol and Other Drug Use Typologies to Sex Risk Behaviors among Vulnerable Women in Cape Town, South Africa.

BACKGROUND: Alcohol and other drug (AOD) use remains an important contributing factor to the spread of HIV in South Africa, mainly because of the strong associations found between AOD use and sex risk behaviors. Specifically, AOD use can lead to disinhibition and impaired judgment that may result in inconsistent condom use and other risky sex behaviors among vulnerable and disempowered women. METHODS: Latent Class Analysis was used to identify AOD use typologies among 720 vulnerable women from a randomized trial baseline assessment in Cape Town, South Africa and to examine whether these AOD use classes predict sex risk for HIV. RESULTS: Three classes emerged with distinct differences in AOD use: the Marijuana and Alcohol class (34.6%) mainly comprised participants who used marijuana and drank alcohol frequently; the High AOD Risk class (26.1%) mainly comprised participants who used methamphetamine and marijuana, reported heavy drinking, and moderate probabilities of Mandrax use; and the Polydrug use class (39.3%) predominately comprised participants who used methamphetamine, marijuana, and Mandrax. Participants in the Marijuana and Alcohol class were less likely to report past-month unprotected sex with their main sex partner compared with participants in the Polydrug Use class. When examining the adjusted model, Black African women were significantly less likely to report past-month unprotected sex with their main sex partner compared with Coloured women. Women who were HIV negative were more likely to report unprotected sex with their main sex partner than women who were HIV positive. CONCLUSION: The fewer substances that women used seemed to serve as protective factors against engaging in AOD-impaired sex. This study provides an important contribution to understand the intersection of AOD use and sexual risk for HIV by measuring polydrug use among vulnerable women and its association with sexual risk taking.
