RESUMO

BACKGROUND: Over 180,000 people use crack cocaine in England, yet provision of smoking equipment to support safer crack use is prohibited under UK law. Pipes used for crack cocaine smoking are often homemade and/or in short supply, leading to pipe sharing and injuries from use of unsafe materials. This increases risk of viral infection and respiratory harm among a marginalised underserved population. International evaluations suggest crack pipe supply leads to sustained reductions in pipe sharing and use of homemade equipment; increased health risk awareness; improved service access; reduction in injecting and crack-related health problems. In this paper, we introduce the protocol for the NIHR-funded SIPP (Safe inhalation pipe provision) project and discuss implications for impact. METHODS: The SIPP study will develop, implement and evaluate a crack smoking equipment and training intervention to be distributed through peer networks and specialist drug services in England. Study components comprise: (1) peer-network capacity building and co-production; (2) a pre- and post-intervention survey at intervention and non-equivalent control sites; (3) a mixed-method process evaluation; and (4) an economic evaluation. Participant eligibility criteria are use of crack within the past 28 days, with a survey sample of ~ 740 for each impact evaluation survey point and ~ 40 for qualitative process evaluation interviews. Our primary outcome measure is pipe sharing within the past 28 days, with secondary outcomes pertaining to use of homemade pipes, service engagement, injecting practice and acute health harms. ANTICIPATED IMPACT: SIPP aims to reduce crack use risk practices and associated health harms; including through increasing crack harm reduction awareness among service providers and peers. Implementation has only been possible with local police approvals. Our goal is to generate an evidence base to inform review of the legislation prohibiting crack pipe supply in the UK. This holds potential to transform harm reduction service provision and engagement nationally. CONCLUSION: People who smoke crack cocaine in England currently have little reason to engage with harm reduction and drug services. Little is known about this growing population. This study will provide insight into population characteristics, unmet need and the case for legislative reform. TRIAL REGISTRATION: ISRCTN12541454  https://doi.org/10.1186/ISRCTN12541454.

RESUMO

BACKGROUND: Low-wage labour migration is an increasing determinant of global health, associated with risks of exploitation, abuse, and unsafe conditions. Despite efforts to prevent irregular migration and initiatives to warn individuals of the risks of trafficking, many migrants still opt for irregular channels, particularly women seeking jobs as domestic workers. Ethiopia is one of the largest source countries for female migrants entering the domestic labour market in the Middle East. This qualitative study explored migration decision making by Ethiopian women traveling to the Middle East for domestic labour, focusing on the use of irregular channels. METHODS: We conducted semistructured interviews with policy stakeholders, migration recruiters, and returnee domestic workers. RESULTS: We identified three main themes that help explain decision making by female migrants and their communities. First, women were not always clear whether they were using legally approved processes, particularly because of the range of individuals involved in arranging migration plans. Second, irregular migration was seen to be quicker and easier than regular migration procedures. Third, study participants believed the risks between irregular and regular migration were similar. CONCLUSION: Our study highlights challenges associated with antitrafficking initiatives that discourage irregular migration and suggests new perspectives to address the health risks linked to labour migration.

RESUMO

BACKGROUND: The 'DREAMS Partnership' promotes a multi-sectoral approach to reduce adolescent girls and young women's (AGYW) vulnerability through a core package of interventions targeting multiple sources of HIV risk-to promote Determined, Resilient, Empowered, AIDS-free, Mentored and Safe (DREAMS) lives. Implementation of such multi-sectoral programmes is complex and requires adaptation to national and local contexts. We describe the early implementation of DREAMS in diverse settings, to identify lessons for the scale-up and replication of combination programmes for young people. METHODS: As part of evaluations underway in six DREAMS sites in three countries (Kenya, South Africa and Zimbabwe), we draw on process evaluation data collected from focus group discussions, key informant interviews, and in-depth interviews with beneficiaries, parents/caregivers, programme managers and opinion leaders. Additionally, structured observations were conducted and Gantt charts completed upon consultation with implementers. We concurrently reviewed documentation available on DREAMS and held cross-site discussions to interpret findings. FINDINGS: All sites sought to implement all components of the DREAMS core package, but how and when they were implemented varied by context. Models of delivery differed, with either multiple or single partners responsible for some or all interventions. Key challenges included the urgent and ambitious expectations of DREAMS; 'layering' multiple interventions across different sectors (health, education, social welfare); supporting individuals' journeys between services to improve uptake and retention; engaging communities beyond direct beneficiaries; avoiding perceived/actual exclusivity; and ensuring continuity of commitment and funding for DREAMS. Despite significant challenges, DREAMS was well-received in the communities and perceived by both beneficiaries and implementers to empower AGYW to remain HIV negative. Structures, protocols and tools were introduced to strengthen referrals and deliver services targeted to the age and circumstances of young people. CONCLUSIONS: The benefits of combinations or integrated 'packages' of interventions are increasingly recognised. Early implementation of DREAMS provides useful lessons for improving coordination across multiple partners using a phased, systematic approach, regular adaptions to each unique context, and ensuring community ownership.

RESUMO

BACKGROUND: Strengthening engagement of female sex workers with health services is needed to eliminate HIV. We assessed the efficacy of a targeted combination intervention for female sex workers in Zimbabwe. METHODS: We did a cluster-randomised trial from 2014 to 2016. Clusters were areas surrounding female sex worker clinics and were enrolled in matched pairs. Sites were randomly assigned (1:1) to receive usual care (free sexual-health services supported by peer educators, including HIV testing on demand, referral for antiretroviral therapy [ART], and health education) or an intervention that supported additional regular HIV testing, on-site initiation of ART, pre-exposure prophylaxis, adherence, and intensified community mobilisation. The primary outcome was the proportion of all female sex workers with HIV viral load 1000 copies per mL or greater, assessed through respondent-driven sampling surveys. We used an adapted cluster-summary approach to estimate risk differences. This trial is registered with Pan African Clinical Trials Registry, number PACTR201312000722390. RESULTS: We randomly assigned 14 clusters to usual care or the intervention (seven in each group). 3612 female sex workers attended clinics in the usual-care clusters and 4619 in the intervention clusters during the study. Half as many were tested (1151 vs 2606) and diagnosed as being HIV positive (546 vs 1052) in the usual-care clusters. The proportion of all female sex workers with viral loads of 1000 copies per mL or greater fell in both study groups (from 421 [30%] of 1363 to 279 [19%] of 1443 in the usual-care group and from 399 [30%] of 1303 to 240 [16%] of 1439 in the intervention group), but with a risk difference at the end of the assessment period of only -2·8% (95% CI -8·1 to 2·5, p=0·23). Among HIV-positive women, the proportions with viral loads less than 1000 copies per mL were 590 (68%) of 869 in the usual-care group and 588 (72%) of 828 in the intervention group at the end of the assessment period, adjusted risk difference of 5·3% (95% CI -4·0 to 14·6, p=0·20). There were no adverse events. INTERPRETATION: Our intervention of a dedicated programme for female sex workers led to high levels of HIV diagnosis and treatment. Further research is needed to optimise programme content and intensity for the broader population. FUNDING: UN Population Fund (through Zimbabwe's Integrated Support Fund funded by UK Department for International Development, Irish Aid, and Swedish International Development Cooperation Agency).

RESUMO

BACKGROUND: "Determined, Resilient, AIDS-free, Mentored and Safe" (DREAMS) is a package of biomedical, social and economic interventions offered to adolescent girls and young women aged 10-24 years with the aim of reducing HIV incidence. In four of the six DREAMS districts in Zimbabwe, DREAMS includes an offer of oral pre-exposure prophylaxis (DREAMS+PrEP), alongside interventions to support demand and adherence, to women aged 18-24 who are at highest risk of HIV infection, including young women who sell sex (YWSS). This evaluation study addresses the question: does the delivery of DREAMS+PrEP through various providers reduce HIV incidence among YWSS Zimbabwe? We describe our approach to designing a rigorous study to assess whether DREAMS+PrEP had an impact on HIV incidence. METHODS: The study design needed to account for the fact that: 1) DREAMS+PrEP was non-randomly allocated; 2) there is no sampling frame for the target population for the evaluation; 3) there are a small number of DREAMS districts (N = 6), and 4) DREAMS+PrEP is being implemented by various providers. The study will use a cohort analysis approach to compare HIV incidence among YWSS in two DREAMS+PrEP districts to HIV incidence among YWSS in non-DREAMS comparison sites. YWSS will be referred to services and recruited into the cohort through a network-based (respondent-driven) recruitment strategy, and followed-up 12- and 24-months after enrolment. Women will be asked to complete a questionnaire and offered HIV testing. Additional complications of this study include identifying comparable populations of YWSS in the DREAMS+PrEP and non-DREAMS comparison sites, and retention of YWSS over the 24-month period. The primary outcome is HIV incidence among YWSS HIV-negative at study enrolment measured by repeat, rapid HIV testing over 24-months. Inference will be based on plausibility that DREAMS+PrEP had an impact on HIV incidence. A process evaluation will be conducted to understand intervention implementation, and document any contextual factors determining the success or failure of intervention delivery. DISCUSSION: HIV prevention products of known efficacy are available. Innovative studies are needed to provide evidence of how to optimise product use through combination interventions to achieve population impact within different contexts. We describe the design of such a study.

RESUMO

BACKGROUND: International migration has become a global political priority, with growing concern about the scale of human trafficking, hazardous work conditions, and resulting psychological and physical morbidity among migrants. Ethiopia remains a significant "source" country for female domestic workers to the Middle East and Gulf States, despite widespread reports of exploitation and abuse. Prior to introduction of a "safe migration" intervention, we conducted formative research to elicit lessons learned by women who had worked as domestic workers abroad. The aim of the study was to identify realistic measures future migrants could take to protect themselves, based on the collective insights and experience of returnees. METHODS: We conducted a qualitative assessment among returnee domestic labour migrants in Amhara Region, Ethiopia, an area considered a "hotspot" for outmigration. We conducted in-depth interviews and focus group discussions with a total of 35 female returnees, exploring risk and protective factors experienced by Ethiopian women during domestic work abroad. We used thematic content analysis to identify practical messages that could improve prospective migrants' preparedness. RESULTS: Returnees described the knowledge and skills they acquired prior to departure and during migration, and shared advice they would give to prospective migrants in their community. Facilitators of positive migration included conforming to cultural and behavioural expectations, learning basic Arabic, using household appliances, and ensuring safety in employers' homes. Respondents also associated confidence and assertiveness with better treatment and respect, and emphasized the importance of access to external communication (e.g. a mobile phone, local sim card, and contact details) for help in an emergency. Following their own challenging or even traumatic experiences, returnees were keen to support resilience among the next wave of migrants. CONCLUSIONS: There is little evidence on practices that foster safer migration, yet attention to human trafficking has led to an increase in pre-migration interventions. These require robust evidence about local risk and protective factors. Our findings identify knowledge, skills, attributes and resources found useful by returnee domestic workers in Amhara region, and have been used to inform a community-based programme aiming to foster better decision-making and preparation, with potential to offer insights for safer migration elsewhere.

RESUMO

INTRODUCTION: Female sex workers (FSW) in sub-Saharan Africa have a higher prevalence of HIV than other women of reproductive age. Social, legal, and structural barriers influence their access to care. Little is known about the HIV diagnosis and care cascade in most countries in Southern Africa. We aimed to describe the HIV diagnosis and care cascade among FSW in Zimbabwe. METHODS: We conducted cross-sectional respondent driven sampling (RDS) surveys of FSW in 14 sites across Zimbabwe as the baseline for a cluster-randomised controlled trial investigating a combination HIV prevention and care package. We administered a questionnaire, tested women for HIV and measured viral load. We report the mean, minimum, and maximum respondent-driven sampling-2 weighted site values. RESULTS: The survey included 2722 women, approximately 200 per site. The mean HIV prevalence was 57.5% (42.8-79.2 site minimum and maximum). Of HIV-positive women, 64.0% (51.6-73.7) were aware of their status, 67.7% (53.4-84.1) of these reported taking antiretroviral therapy, and 77.8% (64.4-90.8) of these had a suppressed HIV viral load (<1000 copies/mL). Among all HIV-positive women, 49.5% had a viral load < 1000 copies/mL. CONCLUSIONS: Although most HIV-positive women aware of their status are accessing antiretroviral therapy, 36.0% of HIV-positive women are unaware of their status and 29.3% of all FSW have an unsuppressed HIV viral load. Investigation and investment into models of testing, treatment, and care are necessary to reach UNAIDS targets for HIV elimination.

RESUMO

BACKGROUND: Community mobilization among female sex workers (SWs) is recognized as an effective strategy to empower SWs and increase their uptake of health services. Activities focus on increasing social cohesion between SWs by building trust, strengthening networks, and encouraging shared efforts for mutual gain. Several studies, however, suggest that high levels of interpersonal competition between SWs can pose a barrier to collective action and support. We conducted a study to examine levels of perceived competition between SWs in Mutare, Hwange and Victoria Falls in Zimbabwe in order to inform development of a community-based intervention for HIV prevention and treatment. This paper focuses on our qualitative findings and their implications for the design of HIV programming in the Zimbabwean context. METHODS: Following a respondent driven sampling (RDS) survey, we explored issues related to social cohesion amongst SWs in Mutare, Hwange and Victoria Falls through in-depth interviews conducted with 22 SWs. Interviews examined dynamics of SWs' relationships and extent of social support, and were analyzed using thematic content analysis using the constant comparative method. Findings are contextualised against descriptive data extracted from the survey, which was analysed using Stata 12, adjusting for RDS. RESULTS: Across all sites, women described protecting each other at night, advising each other about violent or non-paying clients, and paying fines for each other following arrest. In Mutare, women gave additional examples, including physically attacking problem clients, treatment adherence support and shared saving schemes. However, interviews also highlighted fierce competition between women and deep mistrust. This reflects the reported mix of competition and support from the survey of 836 women (Mutare n = 370, Hwange n = 237, Victoria Falls n = 229). In Mutare, 92.8 % of SWs agreed there was a lot of competition; 87.9 % reported that SWs support each other. This contrasted with Victoria Falls and Hwange where fewer agreed there was competition between SWs (70.5 % and 78.0 %), but also fewer reported that SWs support each other at work (55.2 % and 51.2 %). CONCLUSIONS: Women reported being most likely to support each other when confronted with serious danger but maintained high levels of competition for clients, suggesting competition at work does not represent a barrier to support. Examples of practical assistance between SWs provide entry points for our planned community mobilization activities, which aim to broaden trust and support among SWs while acknowledging their professional competition.

RESUMO

INTRODUCTION: Adolescence is a time of physical, emotional and social transitions that have implications for health. In addition to being at high risk for HIV, young key populations (YKP) may experience other health problems attributable to high-risk behaviour or their developmental stage, or a combination of both. METHODS: We reviewed the needs, barriers and gaps for other non-HIV health services for YKP. We searched PubMed and Google Scholar for articles that provided specific age-related data on sexual and reproductive health; mental health; violence; and substance use problems for adolescent, youth or young sex workers, men who have sex with men, transgender people, and people who inject drugs. RESULTS: YKP experience more unprotected sex, sexually transmitted infections including HIV, unintended pregnancy, violence, mental health disorders and substance use compared to older members of key populations and youth among the general population. YKP experience significant barriers to accessing care; coverage of services is low, largely because of stigma and discrimination experienced at both the health system and policy levels. DISCUSSION: YKP require comprehensive, integrated services that respond to their specific developmental needs, including health, educational and social services within the context of a human rights-based approach. The recent WHO Consolidated Guidelines on HIV Prevention, Diagnosis, Treatment and Care for Key Populations are an important first step for a more comprehensive approach to HIV programming for YKP, but there are limited data on the effective delivery of combined interventions for YKP. Significant investments in research and implementation will be required to ensure adequate provision and coverage of services for YKP. In addition, greater commitments to harm reduction and rights-based approaches are needed to address structural barriers to access to care.

RESUMO

INTRODUCTION: Children living with HIV experience particular challenges in accessing HIV care. Children usually rely on adult caregivers for access to care, including timely diagnosis, initiation of treatment and sustained engagement with HIV services. The aim of this study was to inform the design of a community-based intervention to support caregivers of HIV-positive children to increase children's retention in care as part of a programme introducing decentralized HIV care in primary health facilities. METHODS: Using an existing conceptual framework, we conducted formative research to identify key local contextual factors affecting children's linkages to HIV care in Harare, Zimbabwe. We conducted semi-structured interviews with 15 primary caregivers of HIV-positive children aged 6-15 years enrolled at a hospital clinic for at least six months, followed by interviews with nine key informants from five community-based organizations providing adherence support or related services. RESULTS: We identified a range of facilitators and barriers that caregivers experience. Distance to the hospital, cost of transportation, fear of disclosing HIV status to the child or others, unstable family structure and institutional factors such as drug stock-outs, healthcare worker absenteeism and unsympathetic school environments proved the most salient limiting factors. Facilitators included openness within the family, availability of practical assistance and psychosocial support from community members. CONCLUSIONS: The proposed decentralization of HIV care will mitigate concerns about distance and transport costs but is likely to be insufficient to ensure children's sustained retention. Following this study, we developed a package of structured home visits by voluntary lay workers to proactively address other determinants such as disclosure within families, access to available services and support through caregivers' social networks. A randomized controlled trial is underway to assess impact on children's retention in care over two years.

RESUMO

BACKGROUND: Although disproportionately affected by HIV, sex workers (SWs) remain neglected by efforts to expand access to antiretroviral treatment (ART). In Zimbabwe, despite the existence of well-attended services targeted to female SWs, fewer than half of women diagnosed with HIV took up referrals for assessment and ART initiation; just 14% attended more than one appointment. We conducted a qualitative study to explore the reasons for non-attendance and the high rate of attrition. METHODS: Three focus group discussions (FGD) were conducted in Harare with HIV-positive SWs referred from the 'Sisters with a Voice' programme to a public HIV clinic for ART eligibility screening and enrolment. Focus groups explored SWs' experiences and perceptions of seeking care, with a focus on how managing HIV interacted with challenges specific to being a sex worker. FGD transcripts were analyzed by identifying emerging and recurring themes that were specifically related to interactions with health services and how these affected decision-making around HIV treatment uptake and retention in care. RESULTS: SWs emphasised supply-side barriers, such as being demeaned and humiliated by health workers, reflecting broader social stigma surrounding their work. Sex workers were particularly sensitive to being identified and belittled within the health care environment. Demand-side barriers also featured, including competing time commitments and costs of transport and some treatment, reflecting SWs' marginalised socio-economic position. CONCLUSION: Improving treatment access for SWs is critical for their own health, programme equity, and public health benefit. Programmes working to reduce SW attrition from HIV care need to proactively address the quality and environment of public services. Sensitising health workers through specialised training, refining referral systems from sex-worker friendly clinics into the national system, and providing opportunities for SW to collectively organise for improved treatment and rights might help alleviate the barriers to treatment initiation and attention currently faced by SW.

RESUMO

INTRODUCTION: Numerous barriers to optimal uptake of prevention of mother to child transmission (PMTCT) services occur at community level (i.e., outside the healthcare setting). To achieve elimination of paediatric HIV, therefore, interventions must also work within communities to address these barriers and increase service use and need to be informed by evidence. This paper reviews community-based approaches that have been used in resource-limited settings to increase rates of PMTCT enrolment, retention in care and successful treatment outcomes. It aims to identify which interventions work, why they may do so and what knowledge gaps remain. METHODS: First, we identified barriers to PMTCT that originate outside the health system. These were used to construct a social ecological framework categorizing barriers to PMTCT into the following levels of influence: individual, peer and family, community and sociocultural. We then used this conceptual framework to guide a review of the literature on community-based approaches, defined as interventions delivered outside of formal health settings, with the goal of increasing uptake, retention, adherence and positive psychosocial outcomes in PMTCT programmes in resource-poor countries. RESULTS: Our review found evidence of effectiveness of strategies targeting individuals and peer/family levels (e.g., providing household HIV testing and training peer counsellors to support exclusive breastfeeding) and at community level (e.g., participatory women's groups and home-based care to support adherence and retention). Evidence is more limited for complex interventions combining multiple strategies across different ecological levels. There is often little information describing implementation; and approaches such as "community mobilization" remain poorly defined. CONCLUSIONS: Evidence from existing community approaches can be adapted for use in planning PMTCT. However, for successful replication of evidence-based interventions to occur, comprehensive process evaluations are needed to elucidate the pathways through which specific interventions achieve desired PMTCT outcomes. A social ecological framework can help analyze the complex interplay of facilitators and barriers to PMTCT service uptake in each context, thus helping to inform selection of locally relevant community-based interventions.

RESUMO

The aim of the study is to measure trends in condom use in marital and cohabiting relationships in South Africa and Uganda. The data for the study come from two cross sectional surveys conducted in 1998 and 2008 among adult men and women and their partners in KwaZulu-Natal, South Africa and the Jinja district, Uganda. The findings suggest that consistent condom use has risen substantially in both countries. The percentage reporting consistent condom use in the South African sample of husbands increased from 2.5% in 1998 to 12% in 2008 and from 5.5 to 12.5% among wives. In Uganda, the corresponding trends are 1.1-8.3% for husbands and 4-8.6% for wives. In both countries, condom use was considerably higher among the minority of couples where one or both partners were thought to be HIV positive. Increasingly, in both countries condoms are also used for contraceptive purposes. Condoms play a role in preventing HIV infection but the challenge is for prevention programs to broaden their focus toward meeting the needs of married and cohabiting couples.

RESUMO

BACKGROUND: Human trafficking has been recognized both by the international community and many individual states around the world as a serious violation of human rights. Trafficking is associated with extreme violence and a range of physical, mental, and sexual health consequences. Despite the extreme nature of the harm caused by human trafficking, harm is not a concept that is integrated in the definition of trafficking or in policies to address the health of trafficked people. This paper examines the United Kingdom's response to human trafficking as a case study to explore national policy responses to the health needs of trafficked people and assess the willingness of UK authorities to implement international and regional law in securing trafficked people's health rights. METHODS: Between 2007 and 2010, data on the development of the UK response to trafficking were obtained through 46 interviews with key trafficking policy stakeholders and health care providers, participant observation at 41 policy-relevant events, and document collection. Framework analysis was used to analyze the data. RESULTS: International and regional instruments specifically protect the health rights of trafficked people. Yet, UK engagement with trafficked people's health rights has been limited to granting, under certain circumstances, free access to health care services. Changes to trafficked people's entitlements to free health care occurred following the ratification of the Council of Europe Convention on Action Against Trafficking in Human Beings, but had limited impact on trafficked people's access to medical care. CONCLUSIONS: International and regional instruments that provide specific or mandated instruction about states' health care obligations can be effective in furthering the health rights of vulnerable migrant groups. The UK government has demonstrated limited appetite for exceeding its minimum obligations to provide for the health of trafficked people, however, and key principles for promoting the health rights of trafficked people are yet to be fulfilled.

RESUMO

The Intervention with Microfinance for AIDS and Gender Equity (IMAGE) combines microfinance, gender/HIV training and community mobilization (CM) in South Africa. A trial found reduced intimate partner violence among clients but less evidence for impact on sexual behaviour among clients' households or communities. This process evaluation examined how feasible IMAGE was to deliver and how accessible and acceptable it was to intended beneficiaries during a trial and subsequent scale-up. Data came from attendance registers, financial records, observations, structured questionnaires (378) and focus group discussions and interviews (128) with clients and staff. Gender/HIV training and CM were managed initially by an academic unit ('linked' model) and later by the microfinance institution (MFI) ('parallel' model). Microfinance and gender/HIV training were feasible to deliver and accessible and acceptable to most clients. Though participation in CM was high for some clients, others experienced barriers to collective action, a finding which may help explain lack of intervention effects among household/community members. Delivery was feasible in the short term but both models were considered unsustainable in the longer term. A linked model involving a MFI and a non-academic partner agency may be more sustainable and is being tried. Feasible models for delivering microfinance and health promotion require further investigation.

RESUMO

This study assessed individual-level effects of adding micro-enterprise services to a peer-mediated HIV/AIDS intervention among 227 female sex workers (FSWs) in Kenya. Survey data were collected in May-July 2003 and July-August 2005. Two-thirds of participants had operational businesses by end-line survey. Nearly half reported to have stopped sex work. Self-reported weekly mean number of all sexual partners changed from 3.26 (SD 2.45) at baseline to 1.84 (SD 2.15) at end-line survey (P < 0.001). Weekly mean number of casual partners did not change significantly. Weekly mean number of regular partners changed from 1.96 (SD 1.86) to 0.73 (SD 0.98) over the follow-up period (P < 0.001). Consistent condom use with regular partners increased by 18.5% and remained above 90% with casual partners. Micro-enterprise services may empower FSWs by giving them an alternative livelihood when they wish to exit or reduce reliance on sex work. Determinants of successful business operation by FSWs deserve further research.

RESUMO

While much descriptive research has documented positive associations between social capital and a range of economic, social and health outcomes, there have been few intervention studies to assess whether social capital can be intentionally generated. We conducted an intervention in rural South Africa that combined group-based microfinance with participatory gender and HIV training in an attempt to catalyze changes in solidarity, reciprocity and social group membership as a means to reduce women's vulnerability to intimate partner violence and HIV. A cluster randomized trial was used to assess intervention effects among eight study villages. In this paper, we examined effects on structural and cognitive social capital among 845 participants and age and wealth matched women from households in comparison villages. This was supported by a diverse portfolio of qualitative research. After two years, adjusted effect estimates indicated higher levels of structural and cognitive social capital in the intervention group than the comparison group, although confidence intervals were wide. Qualitative research illustrated the ways in which economic and social gains enhanced participation in social groups, and the positive and negative dynamics that emerged within the program. There were numerous instances where individuals and village loan centres worked to address community concerns, both working through existing social networks, and through the establishment of new partnerships with local leadership structures, police, the health sector and NGOs. This is among the first experimental trials suggesting that social capital can be exogenously strengthened. The implications for community interventions in public health are further explored.

RESUMO

OBJECTIVE: To assess effects of a combined microfinance and training intervention on HIV risk behavior among young female participants in rural South Africa. DESIGN: : Secondary analysis of quantitative and qualitative data from a cluster randomized trial, the Intervention with Microfinance for AIDS and Gender Equity study. METHODS: Eight villages were pair-matched and randomly allocated to receive the intervention. At baseline and after 2 years, HIV risk behavior was assessed among female participants aged 14-35 years. Their responses were compared with women of the same age and poverty group from control villages. Intervention effects were calculated using adjusted risk ratios employing village level summaries. Qualitative data collected during the study explored participants' responses to the intervention including HIV risk behavior. RESULTS: After 2 years of follow-up, when compared with controls, young participants had higher levels of HIV-related communication (adjusted risk ratio 1.46, 95% confidence interval 1.01-2.12), were more likely to have accessed voluntary counseling and testing (adjusted risk ratio 1.64, 95% confidence interval 1.06-2.56), and less likely to have had unprotected sex at last intercourse with a nonspousal partner (adjusted risk ratio 0.76, 95% confidence interval 0.60-0.96). Qualitative data suggest a greater acceptance of intrahousehold communication about HIV and sexuality. Although women noted challenges associated with acceptance of condoms by men, increased confidence and skills associated with participation in the intervention supported their introduction in sexual relationships. CONCLUSIONS: In addition to impacts on economic well being, women's empowerment and intimate partner violence, interventions addressing the economic and social vulnerability of women may contribute to reductions in HIV risk behavior.

RESUMO

OBJECTIVES: We sought to obtain evidence about the scope of women's empowerment and the mechanisms underlying the significant reduction in intimate partner violence documented by the Intervention With Microfinance for AIDS and Gender Equity (IMAGE) cluster-randomized trial in rural South Africa. METHODS: The IMAGE intervention combined a microfinance program with participatory training on understanding HIV infection, gender norms, domestic violence, and sexuality. Outcome measures included past year's experience of intimate partner violence and 9 indicators of women's empowerment. Qualitative data about changes occurring within intimate relationships, loan groups, and the community were also collected. RESULTS: After 2 years, the risk of past-year physical or sexual violence by an intimate partner was reduced by more than half (adjusted risk ratio=0.45; 95% confidence interval=0.23, 0.91). Improvements in all 9 indicators of empowerment were observed. Reductions in violence resulted from a range of responses enabling women to challenge the acceptability of violence, expect and receive better treatment from partners, leave abusive relationships, and raise public awareness about intimate partner violence. CONCLUSIONS: Our findings, both qualitative and quantitative, indicate that economic and social empowerment of women can contribute to reductions in intimate partner violence.

RESUMO

Households experience HIV and AIDS in a complex and changing set of environments. These include health and welfare treatment and support services, HIV-related stigma and discrimination, and individual and household social and economic circumstances. This paper documents the experiences of 12 households directly affected by HIV and AIDS in rural KwaZulu Natal, South Africa, between 2002 and 2004. The households were observed during repeated visits over a period of more than a year by ethnographically trained researchers. Field notes were analysed using thematic content analysis to identify themes and sub-themes. This paper focuses on three dimensions of household experience of HIV and AIDS that have received little attention in HIV and AIDS impact studies. First, that experience of HIV and AIDS is cumulative. In an area where population surveys report HIV prevalence rates of over 20% in adults, many households face multiple episodes of HIV-related illness and AIDS deaths. We describe how these challenges affect perceptions and responses within and outside households. Second, while over 50% of all adult deaths are due to AIDS, households continue to face other causes of illness and death. We show how these other causes compound the impact of AIDS, particularly where the deceased was the main income earner and/or primary carer for young children. Third, HIV-related illness and AIDS deaths of household members are only part of the households' cumulative experience of HIV and AIDS. Illness and death of non-household members, for example, former partners who are parents of children within the households or relatives who provide financial support, also impact negatively on households. We also discuss how measuring multiple episodes of illness and deaths can be recorded in household surveys in order to improve quantitative assessments of the impact of HIV and AIDS.
