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.

Sex, drugs, and HIV : Rapid assessment of HIV risk behaviors among street-based drug using sex workers in Durban, South Africa

South Africa is experiencing significant changes in patterns of illicit drug use, including increasing injection and non-injection drug use, and the use of drugs by persons engaged in sex work, both of which could further expand the HIV/AIDS epidemic. In 2005, a rapid ethnographic assessment was conducted in Durban, South Africa, to learn more about patterns of drug use and HIV risk behaviors among drug-using, street-based sex workers. Field teams recruited 52 current injection and non-injection drug users for key informant interviews and focus groups, and they conducted mapping and observation in identified high-risk neighborhoods. Key informants were offered free, voluntary counseling and HIV rapid testing. The results of the assessment indicate that in this population, drugs play an organizing role in patterns of daily activities, with sex work closely linked to the buying, selling, and using of drugs. Participants reported using multiple drugs including crack cocaine, heroin, Ecstasy and Mandrax, and their choices were based on their expectations about the functional role and behavioral and pharmacological properties of the drugs. The organization of sex work and patterns of drug use differ by gender, with males exercising more control over daily routines and drug and sexual transactions than females. Activities of female sex workers are subject to considerable control by individual pimps, many of whom also function as landlords and drug dealers. A strong hold over the overlapping economies of drugs and sex work by a few individuals extends to control of the physical and social settings in which sex is exchanged and drugs are sold and used as well as the terms under which sex work is carried out. The potential for accelerated HIV spread is considerable given the evidence of overlapping drug-using and sexual risk behaviors and the mixing patterns across drug and sexual risk networks.

Food insecurity and its association with co-occurring postnatal depression, hazardous drinking, and suicidality among women in peri-urban South Africa

BACKGROUND Although the public health impacts of food insecurity and depression on both maternal and child health are extensive, no studies have investigated the associations between food insecurity and postnatal depression or suicidality. METHODS We interviewed 249 women three months after they had given birth and assessed food insecurity, postnatal depression symptom severity, suicide risk, and hazardous drinking. Multivariable Poisson regression models with robust standard errors were used to estimate the impact of food insecurity on psychosocial outcomes. RESULTS Food insecurity, probable depression, and hazardous drinking were highly prevalent and co-occurring. More than half of the women (149 [59.8%]) were severely food insecure, 79 (31.7%) women met screening criteria for probable depression, and 39 (15.7%) women met screening criteria for hazardous drinking. Nineteen (7.6%) women had significant suicidality, of whom 7 (2.8%) were classified as high risk. Each additional point on the food insecurity scale was associated with increased risks of probable depression (adjusted risk ratio [ARR], 1.05; 95% CI, 1.02-1.07), hazardous drinking (ARR, 1.04; 95% CI, 1.00-1.09), and suicidality (ARR, 1.12; 95% CI, 1.02-1.23). Evaluated at the means of the covariates, these estimated associations were large in magnitude. LIMITATIONS The study is limited by lack of data on formal DSM-IV diagnoses of major depressive disorder, potential sample selection bias, and inability to assess the causal impact of food insecurity. CONCLUSION Food insecurity is strongly associated with postnatal depression, hazardous drinking, and suicidality. Programmes promoting food security for new may enhance overall psychological well-being in addition to improving nutritional status.

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.

Review of injection drug use in six African countries: Egypt, Kenya, Mauritius, Nigeria, South Africa and Tanzania.

Injection drug use (IDU) is becoming an increasingly important mode of HIV transmission globally. The number of African countries experiencing IDU is reported to be growing. This is cause for concern as the phenomenon of IDU is arising within the context of an established and growing HIV epidemic. This article provides a concise review of the available literature pertaining to IDU within six African countries, namely Egypt, Kenya, Mauritius, Nigeria, South Africa and Tanzania. The available information contradicts the prevailing view that IDU is extremely rare or non-existent in most African countries. IDU populations within the selected countries are shown to engage in high-risk sexual and injecting behaviours. IDUs in Africa have the potential to provide a significant contribution to the spread of HIV/AIDS on the continent.

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.

It's important to take your medication everyday okay? An evaluation of counselling by lay counsellors for ARV adherence support in the Western Cape, South Africa

There is growing interest in standard care programmes for antiretroviral (ARV) adherence support. In South Africa, individual counselling following ARV initiation is a main strategy for supporting adherence in the public sector. Egan’s client-centred “Skilled Helper” counselling model is the predominant model used in HIV counselling in this context. This study evaluated counselling delivered by lay ARV adherence counsellors in Cape Town in terms of adherence to Egan’s model. Thirty-eight transcripts of counselling sessions with non-adherent patients were analysed based on the methods of content analysis. These sessions were conducted by 30 counsellors. Generally counsellors’ practice adhered neither to Egan’s model nor a client-centred approach. Inconsistent with evidence-based approaches to counselling for ARV adherence support, counsellors mainly used information-giving and advice as strategies for addressing clients’ non-adherence. Recommendations for improving practice are made. The question as to how appropriate strategies from developed countries are for this setting is also raised.

Community-based prenatal screening for postpartum depression in a South African township.

To assess the feasibility of using community health workers to administer short or ultra‐short screening instruments during routine community‐based prenatal outreach for detecting probable depression at 12 weeks postpartum.

The Feasibility of Implementing a Sexual Risk Reduction Intervention in Routine Clinical Practice at an ARV Clinic in Cape Town: A Case Study

This case study with one lay adherence counsellor assessed the implementation of Options for Health, a sexual risk-reduction intervention based on Motivational Interviewing (MI), in an antiretroviral clinic in Cape Town, South Africa. In most cases Options was not delivered with fidelity and less than one-third of intended recipients received it; the counsellor often forgot to do Options, was unsure how to deal with particular cases and felt that there was not always time to do Options. Options was not implemented in a way that was consistent with MI. Revisions to the implementation plan and training programme are required.

Predictors of poor adherence among people on antiretroviral treatment in Cape Town, South Africa: a case-control study

A case-control study was conducted to describe the frequency with which structural- and individual-level barriers to adherence are experienced by people receiving antiretroviral (ARV) treatment and to determine predictors of non-adherence. Three hundred adherent and 300 non-adherent patients from 6 clinics in Cape Town completed the LifeWindows Information-Motivation-Behavioral Skills ART Adherence Questionnaire, the Substance Abuse and Mental Illness Symptoms Screener and the Structural Barriers to Clinic Attendance (SBCA) and Medication-taking (SBMT) scales. Overall, information-related barriers were reported most frequently followed by motivation and behaviour skill defects. Structural barriers were reported least frequently. Logistic regression analyses revealed that gender, behaviour skill deficit scores, SBCA scores and SBMT scores predicted non-adherence. Despite the experience of structural barriers being reported least frequently, structural barriers to medication-taking had the greatest impact on adherence (OR: 2.32, 95% CI: 1.73 to 3.12), followed by structural barriers to clinic attendance (OR: 2.06, 95% CI: 1.58 to 2.69) and behaviour skill deficits (OR: 1.34, 95% CI: 1.05 to 1.71). Our data indicate the need for policy directed at the creation of a health-enabling environment that would enhance the likelihood of adherence among antiretroviral therapy users. Specifically, patient empowerment strategies aimed at increasing treatment literacy and management skills should be strengthened. Attempts to reduce structural barriers to antiretroviral treatment adherence should be expanded to include increased access to mental health care services and nutrition support.
