Rapid assessment of drug-related HIV risk among men who have sex with men in three South African cities

The current assessment was undertaken to examine the link between drug use and sexual risk behavior among men who have sex with men (MSM) in locations known to have high prevalence rates of drug use and sexual risk behavior in Cape Town, Durban and Pretoria, South Africa. Street intercepts and purposive snowball sampling were used to recruit drug-using MSM. A rapid assessment was undertaken which included observation, mapping, key informant interviews and focus group interviews with MSM. Drug using key informants were tested for HIV. The use of drugs like crack cocaine, cannabis and methamphetamine to specifically facilitate sexual encounters was evident. Drugs led to inconsistent condom use and other high-risk sexual activities despite HIV risk knowledge being high. Many injecting drug-using MSM shared needles and reused equipment. Among MSM who agreed to HIV testing, one-third tested positive. Views about drug and HIV treatment and preventive services and their efficacy were mixed. Various barriers to accessing services were highlighted including homosexual stigmatization and availability of drugs in treatment facilities. Recommendations include addressing the gap between HIV-risk knowledge and practice, extending VCT services for MSM, increasing the visibility of drug abuse services within communities, addressing concerns about drug availability in treatment centers as well as reintegration issues and the need for after-care services, reducing stigmatization in drug and HIV services for MSM and finally, strengthening the link between drug treatment services and HIV prevention by integrating HIV/drug-related risks into HIV prevention efforts and HIV risks into drug use prevention efforts.

Adolescent methamphetamine use and sexual risk behaviour in secondary school students in Cape Town, South Africa

This study investigated involvement in substance use and sexual activities among adolescents in Cape Town, and specifically the associations between methamphetamine use and sexual risk behaviours. Data were collected from 15 randomly selected and 15 matched schools in Cape Town via quantitative questionnaires. Students used hand-held computers (PDAs) to answer the questions. A total of 4605 grade 9 students were sampled. Male and female students were almost equally likely to have used methamphetamine at least once (13% versus 12%). Students who had used methamphetamine in the past 30 days were significantly more likely to have had vaginal, anal or oral sex than students who had never used it, to have been pregnant/been responsible for a pregnancy and to have been diagnosed with a sexually transmitted infection. Logistic regression analysis indicated significant associations between methamphetamine use in the past 12 months and engaging in vaginal and anal sex. Drug abuse and sexually transmitted infections (STI) prevention services should incorporate the link between drugs and STI into their prevention and education strategies, especially those aimed at school-going adolescents.

Effectiveness of early interventions for substance-using adolescents: findings from a systematic review and meta-analysis

BackgroundInformation on the impact of available interventions that address adolescent substance use and delinquency can inform investment choices. This article aims to identify and evaluate early interventions that target adolescent substance use as a primary outcome, and criminal or delinquent behaviours as a secondary outcome.MethodA systematic review of early interventions for adolescent substance use and behavioural outcomes was conducted.ResultsWe identified nine studies using specific search strategies. All but one of the studies reported the use of brief intervention strategies. Only seven studies contained information which allowed for the calculation of an effect size, and were therefore included in the meta-analysis. The overall effect size for all outcomes combined was small but significant (g = 0.25, p < 0.001). The overall outcome for substance use was also small but significant (g = 0.24, p < 0.001). For studies with behavioural outcomes, the overall effect size reached significance (g = 0.28, p < 0.001). In general, subgroup analysis showed that individual interventions with more than one session had a stronger effect on the outcomes of interest.ConclusionsEarly interventions for adolescent substance use do hold benefits for reducing substance use and associated behavioural outcomes. Interventions are most promising if delivered in an individual format and over multiple sessions. One intervention in particular had large effect sizes. As all the interventions were tested in developed countries, further testing is needed in low- and middle-income countries where there is a lack of research on evidence-based interventions for adolescent risk behaviours. Additional recommendations for policy and practice are provided in this paper.

Rapid assessment of drug use and sexual HIV risk patterns among vulnerable drug- using populations in Cape Town, Durban and Pretoria, South Africa

This exploratory study examines the links between drug use and high-risk sexual practices and HIV in vulnerable drug-using populations in South Africa, including commercial sex workers (CSWs), men who have sex with men (MSM), injecting drug users (IDUs) and non-injecting drug users who are not CSWs or MSM (NIDUs). A rapid assessment ethnographic study was undertaken using observation, mapping, key informant interviews and focus groups in known ‘hotspots’ for drug use and sexual risk in Cape Town, Durban and Pretoria. Key informant (KI) and focus group interviews involved drug users and service providers. Purposeful snowball sampling and street intercepts were used to recruit drug users. Outcome measures included drug-related sexual HIV risk behaviour, and risk behaviour related to injection drug use, as well as issues related to service use. HIV testing of drug-using KIs was conducted using the SmartCheck Rapid HIV-1 Antibody Test. Non-injection drug use (mainly cannabis, methaqualone, crack cocaine and crystal methamphetamine) and injection drug use (mainly heroin) was occurring in these cities. Drug users report selling sex for money to buy drugs, and CSWs used drugs before, during and after sex. Most (70%) of the drug-using KIs offered HIV testing accepted and 28% were positive, with rates highest among CSWs and MSM. IDUs reported engaging in needle sharing and needle disposal practices that put them and others at risk for contracting HIV. There was a widespread lack of awareness about where to access HIV treatment and preventive services, and numerous barriers to accessing appropriate HIV and drug-intervention services were reported. Multiple risk behaviours of vulnerable populations and lack of access to HIV prevention services could accelerate the diffusion of HIV. Targeted interventions could play an important role in limiting the spread of HIV in and through these under-reached and vulnerable populations.

A brief intervention for drug use, sexual risk behaviours and violence prevention with vulnerable women in South Africa: a randomised trial of the Women's Health CoOp

Objective To assess the impact of the Womens Health CoOp (WHC) on drug abstinence among vulnerable women having HIV counselling and testing (HCT). Design Randomised trial conducted with multiple follow-ups. Setting 15 communities in Cape Town, South Africa. Participants 720 drug-using women aged 18–33, randomised to an intervention (360) or one of two control arms (181 and 179) with 91.9% retained at follow-up. Interventions The WHC brief peer-facilitated intervention consisted of four modules (two sessions), 2 h addressing knowledge and skills to reduce drug use, sex risk and violence; and included role-playing and rehearsal, an equal attention nutrition intervention, and an HCT-only control. Primary outcome measures Biologically confirmed drug abstinence measured at 12-month follow-up, sober at last sex act, condom use with main and casual sex partners, and intimate partner violence. Results At the 12-month endpoint, 26.9% (n=83/309) of the women in the WHC arm were abstinent from drugs, compared with 16.9% (n=27/160) in the Nutrition arm and 20% (n=31/155) in the HCT-only control arm. In the random effects model, this translated to an effect size on the log odds scale with an OR of 1.54 (95% CI 1.07 to 2.22) comparing the WHC arm with the combined control arms. Other 12-month comparison measures between arms were non-significant for sex risk and victimisation outcomes. At 6-month follow-up, women in the WHC arm (65.9%, 197/299) were more likely to be sober at the last sex act (OR1.32 (95% CI 1.02 to 1.84)) than women in the Nutrition arm (54.3%, n=82/152). Conclusions This is the first trial among drug-using women in South Africa showing that a brief intervention added to HCT results in greater abstinence from drug use at 12 months and a larger percentage of sexual activity not under the influence of substances.

Substance use gender inequity violence and sexual risk among couples in Cape Town.

Alcohol and other drug use, gender power inequities and violence are key contributors to sexual risks for HIV among South African men and women. Little is known about the intersection between these sex-risk behaviours among couples in established heterosexual relationships. We conducted 10 focus-group discussions with men and women in relationships of 1 year or longer recruited from shebeens (informal taverns) in Cape Town, South Africa. Participants described: high levels of alcohol consumption at shebeens; low levels of condom use with main and casual sex partners; gender roles disfavouring womens condom negotiating power that also promoted economic dependency on male partners; men often spending a portion of the household income on alcohol and other drugs and sex with others in shebeens; loss of household income driving women to trade sex to provide for their families; and sexual violence and the exploitation of women occurring in shebeens. Findings highlight how the social contexts of alcohol and other drug use, gender inequitable norms and gender violence promote HIV risk within established heterosexual relationships in South African communities. Evidence of this kind should inform the design of HIV-risk-reduction interventions tailored to heterosexual couples who drink alcohol in shebeens.

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.

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

BackgroundAlcohol 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.MethodCross-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.ResultsEthnic 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.ConclusionsFindings 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.

HIV-Risk Behavior Among Injecting or Non-Injecting Drug Users in Cape Town, Pretoria, and Durban, South Africa

The rapid assessment aimed to describe drug use and sexual practices that place injection and noninjection drug users (IDUs/NIDUs) at risk for HIV in South Africa. The sample comprised 85 key-informant (KI) and focus-group (FG) interviewees in or serving locations with high levels of drug use in Cape Town, Durban, and Pretoria. HIV testing of drug-using KIs was conducted using the SmartCheck Rapid HIV-1 Antibody Test. The findings indicated that commonly used drugs had differing effects on sexual and drug-use practices. Risky injecting behaviors among IDUs were common, and most interviewees engaged in sex when on drugs, some without condoms. These behaviors were also influenced by trust in intimate relationships. Injection drug users seemed more knowledgeable about HIV transmission than NIDUs, and 20% of IDUs who agreed to HIV screening tested positive. Views about drug- and HIV-intervention services, accessibility, and their efficacy were mixed. The findings suggest greater synergy is needed between drug- and HIV-intervention sectors and that consideration should be given to making various risk-reduction strategies more accessible. The studys limitations have been noted.

Eating disordered behaviors and media exposure

BackgroundThis study examined this relationship between eating disordered behaviors and exposure to ideal-type media in a sample of South African university students, who could be expected to have reasonably high levels of media exposure. Possible underlying reasons for this complex relationship were also investigated.MethodIt examined the relationship via both quantitative (using a questionnaire that included the EAT-26 and a media composite variable) and qualitative methods (interviews) in the sample.ResultsIn the quantitative part, sex and level of media exposure significantly predicted scores on the EAT-26. Women obtained scores that indicated they were more “at risk” for anorexia nervosa than men, especially women with higher levels of media exposure. In the qualitative part of the study grounded theory was used to explore how this relationship was formed. Results indicated that numerous factors, some related to the media, predispose women to disordered eating behaviors. The interviewees were then more likely to use ideal-type media heavily to sustain their disordered eating behaviors. Heavy use of the media led participants to attempt a number of strategies to change their appearance to resemble those in the media, with various degrees of success.ConclusionThe model developed by the qualitative research indicated that the media are not necessarily always the cause of pathological eating, but that they interact with other factors in the development of symptoms of anorexia nervosa for these women.
