Abstract
BACKGROUND Women who use heroin and other drugs (WWUD) are a key population with elevated risk of physical and sexual violence perpetrated by intimate partners and non-partners. While housing instability has been shown to be associated with violence in high-income settings, this is an underexplored topic in sub-Saharan Africa. In this research, we aimed to assess the relationship between housing instability and various forms of violence within a sample of WWUD in Dar es Salaam. METHODS This analysis uses data from a parent study from 2018. A total of 200 WWUD were recruited through respondent-driven sampling methods and administered a survey. Two multivariable logistic regression models were built to assess the relationship between housing instability and physical violence (Model 1) and housing instability and sexual violence (Model 2) while controlling for a number of sociodemographic characteristics. RESULTS Approximately 35% of participants were classified as housing unstable. More than half of participants (62%) reported experiencing physical violence in the past 12 months, and more than a third (36%) reported sexual violence in the same time period. Housing instability was found to be independently associated with both physical and sexual violence victimization in the past year when adjusting for covariates (Model 1 adjusted odds ratio [AOR]: 2.40, 95% CI 1.22-4.46; Model 2 AOR: 1.93. 95% CI 1.02-3.67). CONCLUSION To our knowledge, this is the first study to document a significant association between housing instability and violence among WWUD communities in sub-Saharan Africa. This analysis adds to the growing body of literature on the relationship between stable housing and livelihood and health outcomes across differing populations. The cyclical nature of housing instability and violence may be disrupted through housing programming that provides safety, security, and stability for WWUD.

Socio-cognitive factors influencing access to HIV prevention services among people who inject drugs in Dar es Salaam, Tanzania: An integrated bio-behavioural survey. PLoS One 2022; 17:e0261500. [PMID: 35089928 PMCID: PMC8797198 DOI: 10.1371/journal.pone.0261500] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/26/2020] [Accepted: 12/03/2021] [Indexed: 11/22/2022] Open
Abstract
Introduction People who inject drugs (PWID) in Sub-Saharan Africa have limited access to comprehensive HIV services. While it is important to inform programming, knowledge about factors influencing access to comprehensive HIV services is scarce. We assessed the proportions of PWID with access to HIV prevention services and associated socio-cognitive factors in Tanzania. Methods A cross-sectional survey was conducted among PWID between October and December 2017 in Dar es Salaam, Tanzania. Data on access to HIV prevention services, demographics and selected socio-cognitive factors were collected through structured face-to-face interviews. Weighted descriptive and forward selection multivariable logistics regression analyses were done to assess independent associations between HIV prevention services and predictors of interest. The results were two tailed and a p-value of less than 0.05 was considered statistically significant. Results The study included 611 PWID (males: 94.4%) with a median age of 34 years (Interquartile Range (IQR), 29–38). A large majority of participants reported to have access to condoms (87.8%), sterile needles/syringes (72.8%) and ever tested for HIV (66.0%). About half (52.0%) reported to have used condoms in the past one month and about a third (28.5%) accessed a peer educator. The odds of testing for HIV decreased among participants who perceived their HIV risk to be high (aOR = 0.29; 95%CI: 0.17–0.49) and those experienced sexual violence (aOR = 0.60; 95%CI 0.37–0.98). However, the odds of testing for HIV increased among participants with secondary level of education (aOR = 2.16; 95%CI: 1.06–5.55), and those who reported having correct comprehensive HIV knowledge (CCHK) (aOR = 1.63; 95%CI 1.12–2.41). The odds of access to condoms increased among females (aOR = 2.23; 95%CI: 1.04–5.02) but decreased among participants with secondary level of education (aOR = 0.41; 95%CI: 0.19–0.84), an income of >TZS 200,000 (aOR = 0.39; 95%CI: 0.23–0.66) and those who perceived their HIV risk to be high (aOR = 0.13; 95%CI: 0.03–0.36). The odds of access to peer educators was higher among participants with primary (aOR = 1.61; 95%CI: 1.01–2.26), and secondary (aOR = 2.71; 95%CI: 1.39–5.33) levels of education. The odds of access to sterile needle and syringe decreased among participants who perceived their HIV risk to be high (aOR = 0.11;95%CI 0.05–0.22), and low-medium (aOR = 0.25;95%CI 0.11–0.52) but increased among those with primary level of education (aOR = 1.72;95%CI 1.06–2.78). Conclusion Access to condom, HIV testing, sterile needles and syringes were relatively high among PWID. However, condom use and access to peer educators was relatively low. HIV knowledge and risk perception, gender, education, and sexual violence influenced access to HIV prevention services. There is an urgent need to address the identified socio-cognitive factors and scale up all aspects of HIV prevention services to fast-track attainment of the 2025 UNAIDS goals and ending the HIV epidemic.

Abstract
OBJECTIVE To determine the prevalence of tuberculosis (TB) disease and infection as well as incident TB disease among people who use drugs (PWUD) attending Medication Assisted Treatment (MAT) clinics in Dar-es-Salaam, Tanzania. METHODS In this prospective cohort study, a total of 901 consenting participants were enrolled from November 2016 to February 2017 and a structured questionnaire administered to them through the open data kit application on android tablets. Twenty-two months later, we revisited the MAT clinics and reviewed 823 of the 901 enrolled participant's medical records in search for documentation on TB disease diagnosis and treatment. Medical records reviewed included those of participants whom at enrolment were asymptomatic, not on TB disease treatment, not on TB preventive therapy and those who had a documented tuberculin skin test (TST) result. RESULTS Of the 823 medical records reviewed 22 months after enrolment, 42 had documentation of being diagnosed with TB disease and initiated on TB treatment. This is equivalent to a TB disease incidence rate of 2,925.2 patients per 100,000 person years with a total follow up time of 1,440 person-years. At enrolment the prevalence of TB disease and TB infection was 2.6% and 54% respectively and the HIV prevalence was 44% and 16% among females and males respectively. CONCLUSION PWUD attending MAT clinics bear an extremely high burden of TB and HIV and are known to have driven TB epidemics in a number of countries. Our reported TB disease incidence is 12 times that of the general Tanzanian incidence of 237 per 100,000 further emphasizing that this group should be prioritized for TB screening, testing and treatment. Gender specific approaches should also be developed as female PWUDs are markedly more affected with HIV and TB disease than male PWUDs.

Drug Alcohol Depend 2021; 218:108419. [PMID: 33296857 PMCID: PMC7759029 DOI: 10.1016/j.drugalcdep.2020.108419] [Citation(s) in RCA: 7] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/28/2020] [Revised: 09/25/2020] [Accepted: 10/31/2020] [Indexed: 12/13/2022]
Abstract
BACKGROUND As opioid overdoses and deaths increase globally, little is known about these dimensions in Sub-Saharan Africa. In this paper, we explore factors associated with opioid overdose experiences among a sample of women who use opioids in Dar es Salaam, Tanzania. METHODS We conducted a cross-sectional survey with 200 women who use opioids in Dar es Salaam, Tanzania, recruited via respondent-driven sampling. We fitted unadjusted and adjusted log-binomial regression models with robust standard errors to examine associations between participant characteristics and reporting ever had an opioid overdose in terms of prevalence ratios. RESULTS Thirty-four percent (n = 68) of participants reported having ever had an opioid overdose. In the final adjusted model, having ever attempted to stop using heroin (adj. PR = 1.46, 95% CI: 1.01-2.12), sleeping outside in the past 6 months (adj. PR = 1.93, 95% CI: 1.29-2.91), injecting drugs (adj. PR = 1.78, 95% CI: 1.19-2.66), alcohol use (adj. PR = 1.56, 95% CI: 1.09-2.23), and having moderately severe to severe depression (adj. PR = 3.10, 95% CI: 1.07-8.97) were all found to be significantly associated with having ever had an opioid overdose. CONCLUSIONS We demonstrate factors associated with opioid overdose among women who use drugs in Tanzania that may not be addressed with injection-focused harm reduction efforts. Our findings suggest the need for overdose surveillance efforts and further work to characterize overdose risks in this context in order to design relevant, targeted interventions to prevent opioid overdose in sub-Saharan Africa.

[PMID: 32019536 PMCID: PMC7001263 DOI: 10.1186/s12889-020-8294-8] [Citation(s) in RCA: 8] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2019] [Accepted: 01/28/2020] [Indexed: 12/12/2022] Open
Abstract
Background Tanzania has witnessed a significant decrease in the prevalence of human immunodeficiency virus (HIV) and viral hepatitis in the general population attributed to several interventional measures. It is uncertain whether this decline has also occurred among people who inject drugs (PWID). This study aimed to determine the seroprevalence of HIV, Hepatitis B and C viruses infection among PWID recruited from their hotspot sites in Dar es Salaam, Tanzania. Methods A cross-sectional study conducted between June and September 2017 recruited PWID from pre-identified hotspot sites using a snowball referral sampling technique. A structured questionnaire was used to obtain information regarding socio-demographic characteristics, behaviour and drug use. Blood was tested for the presence of IgG antibodies against HIV and Hepatitis C virus (HCV) and hepatitis B surface antigen (HBsAg). Data were entered in the computer using excel software and analysed using Statistical Package for Social Sciences version 20. Results A total of 219 PWID were recruited, the majority of whom were males (74.9%), unmarried (60.7%), had low education (62.6%) and low income (57.1%). The median age was 39 years, with an inter-quartile range of 35–43. Approximately 32.0% had a history of drug injection for more than 3 years, 79.9% were injecting drugs more than 3 times per day and 47.5% were sharing needles. The overall prevalence of HIV, HBsAg, and HCV was 33.8, 7.8, and 50.2%, respectively. There was serologic evidence of at least one infection for 68.9%, while 22.4% had two or more infections. HIV infection was independently associated with being married, while HCV was associated with injecting drugs for more than 3 years and unprotected sex. Conclusion Over two-third of PWID had serologic evidence of infection with at least one virus while 22.4% having at least two infections. The high prevalence of HIV and viral hepatitis infections among PWID may hamper initiatives of ending HIV and viral hepatitis epidemics in Tanzania.

[PMID: 31146748 PMCID: PMC6543607 DOI: 10.1186/s12954-019-0307-5] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2018] [Accepted: 05/16/2019] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Injecting drug use (IDU) is a key driver of the HIV epidemic particularly when individuals experience psychosocial conditions and risky sexual behavior in a syndemic manner. This study sets out to assess evidence of a syndemic pattern of psychosocial conditions (IDU, depression, intimate partner violence (IPV)) on one the hand and risky sexual behavior on the other while accounting for the socio-economic disadvantage among women who inject drugs (WWID) in low-income urban settings in Kenya. METHODS Using a cross-sectional study design, this study recruited 306 WWIDs from two sites in Nairobi between January 2017 and July 2017. Multiple methodologies including descriptive analyses of co-occurrences of psychosocial conditions at the individual level, standard logistic regression analyses to examine relationships and interactions within and between psychosocial conditions and risky sexual behavior, and classification trees algorithm for predictive modeling via machine learning were employed. RESULTS The prevalence of the psychosocial conditions was as follows: IDU, 88%; depression, 77.1%; and IPV, 84%. The prevalence of risky sexual behavior was 69.3%. IDU and depression were related to each other (P < 0.05) and each of them with risky sexual behavior (P < 0.05). The highest 2-way and 3-way co-occurrence of conditions were reported in IDU and depression (72%) and in IDU, depression, and risky sexual behavior (62%), respectively, indicating clustering of the conditions at the individual level. Further, each additional psychosocial condition (IDU and depression) was associated with sixfold odds (P = 0.000) of having risky sexual behavior suggesting a dose-response relationship. Logistic regression analyses incorporating multiplicative interactive effects returned three significant variables (P < 0.05): IDU*depression interaction effect, "Age when delivered the first child," and "Income." Classification tree modeling represented a 5-level interaction analysis with IDU and depression predicted to have the highest influence on risky sexual behavior. CONCLUSION Findings provide possible evidence of a syndemic pattern involving IDU, depression, and risky sexual behavior suggesting the need for an integrated approach to the implementation of harm reduction interventions among WWID in low-income urban settings in Kenya. This work highlights the need for further studies to authenticate the findings and to characterize pathways in the syndemic development in WWID.

Abstract
BACKGROUND Despite being a priority population for HIV prevention and harm reduction programs, the sexual and reproductive health (SRH) needs of women who inject drugs are being overlooked. Furthermore, models for providing integrated SRH, HIV, and harm reduction services for women who inject drugs are rare. This article reports the development of community-based outreach services that integrated family planning and other SRH interventions with HIV and harm reduction services for this population in coastal Kenya. METHODS Using mixed-methods implementation research, a qualitative baseline needs assessment was conducted with women who inject drugs and harm reduction stakeholders using a combination of in-depth interviews and focus group discussions. The qualitative data from participants was subjected to thematic analysis using Nvivo. Based on the baseline needs assessment, integration of SRH into existing HIV and harm reduction services was implemented. After two years of implementation, an evaluation of the program was conducted using a combination of qualitative interviews and review of quantitative service delivery records and other program documents. The process, impacts, and challenges of integrating SRH into a community-based HIV prevention and harm reduction program were identified. RESULTS This article highlights: 1) low baseline utilization of family planning services among women who inject drugs, 2) improved utilization and high acceptability of outreach-based provision of SRH services including contraception among this population, 3) importance of training, capacity strengthening, technical support and financial resourcing of community-based organizations to integrate SRH into HIV prevention and harm reduction services, and 4) the value of beneficiary involvement, advocacy, and collaboration with other partners in the planning, designing and implementing of SRH interventions for women who inject drugs. CONCLUSIONS Women who inject drugs in this study had low utilization of family planning and other SRH services, which can be improved through the integration of contraceptive and other SRH interventions into existing outreach-based HIV prevention and harm reduction programs. This integration is acceptable to women who inject drugs, and is programmatically feasible. For successful integration, a rights-based beneficiary involvement, coupled with sustainable technical and financial capacity strengthening at the community level is essential.

Abstract
Background The HIV epidemic in Georgia is increasing. Data shows that compared to previous years, Georgia has increasingly more HIV-infected individuals than previous assessments. Select client groups remain hard to reach by harm reduction programs. The need for innovative strategies to involve these individuals is imperative. Methods The following study examines demographics and risk factors of participants, previously known and not known to harm reduction services, for HIV and other infectious disease in towns across Georgia in 2015 and compares risk among different groups, while also assessing the rationale for implementing Peer-Driven Interventions in Georgian Harm Reduction activities. Important differences in demographics and risk profile are thought to exist between those exposed, and those unexposed, to harm reduction activity. Results Important and striking differences between previously known and unknown participants, including demographic background and risk profile and behaviours exist in the drug using community. These differences can potentially explain some of the rise of HIV prevalence in Georgia. Conclusion Significant differences exist between known and unknown drug users in Georgia, the differences between which are crucial for planning future and holistic harm reduction activities in Georgia, regionally and globally. The research advocates for smarter harm reduction activity, adds to the global evidence for the utility of Peer-Driven Intervention, and encourages sustained global effort for reduction of blood-borne disease burden globally.

Abstract
Purpose of review Opioid use disorder (OUD) is a global phenomenon and is on the rise in Africa, denoting a shift from historical patterns of drug transport to internal consumption. In contrast, opioids for clinical pain management in Africa remain among the least available globally. This region also has the highest HIV and HCV disease burden, and the greatest shortages of health workers and addiction treatment. We undertook a systematic review of the literature to describe opioid use in Africa and how it is being addressed. Recent findings A total of 84 articles from 2000 to 2018 were identified. Descriptions of country-specific populations and patterns of opioid misuse were common. A smaller number of articles described interventions to address OUD. Summary OUD occurs in sub-Saharan Africa, with attendant clinical and social costs. Evidence-based policies and health system resources are needed to promote OUD prevention and management, and infectious disease transmission reduction.

Strengthening HIV therapy and care in rural Tanzania affects rates of viral suppression. J Antimicrob Chemother 2018; 72:2069-2074.

Abstract
Objectives To assess viral suppression rates, to assess prevalence of acquired HIV drug resistance and to characterize the spectrum of HIV-1 drug resistance mutations (HIV-DRM) in HIV-1-infected patients in a rural Tanzanian HIV cohort. Methods This was a cross-sectional study nested within the Kilombero and Ulanga Antiretroviral Cohort. Virological failure was defined as HIV-1 RNA ≥50 copies/mL. Risk factors associated with virological failure and with the development of HIV-DRM were assessed using logistic regression. Results This study included 304 participants with a median time on ART of 3.5 years (IQR = 1.7-5.3 years); 91% were on an NNRTI-based regimen and 9% were on a boosted PI-based regimen. Viral suppression was observed in 277/304 patients (91%). Of the remaining 27 patients, 21 were successfully genotyped and 17/21 (81%) harboured ≥1 clinically relevant HIV-DRM. Of these, 13/17 (76.5%) had HIV-1 plasma viral loads of >1000 copies/mL. CD4 cell count <200 cells/mm(3) at the time of recruitment was independently associated with a close to 8-fold increased odds of virological failure [adjusted OR (aOR) = 7.71, 95% CI = 2.86-20.78, P < 0.001] and with a >8-fold increased odds of developing HIV-DRM (aOR = 8.46, 95% CI = 2.48-28.93, P = 0.001). Conclusions High levels of viral suppression can be achieved in rural sub-Saharan Africa when treatment and care programmes are well managed. In the absence of routine HIV sequencing, the WHO-recommended threshold of 1000 viral RNA copies/mL largely discriminates virological failure secondary to HIV-DRM.

Abstract
There is limited data regarding women who inject drugs, and how harm-reduction services can be made more women-centered. This study explored experiences of Kenyan women who inject drugs, with regard to access to HIV, harm reduction and sexual and reproductive health (SRH) services. A total of 45 women who inject drugs and 5 key stakeholders participated in-depth interviews and focus group discussions. Thematic analysis of the data revealed that stigma, long distances, lack of confidentiality, user fees, multiple appointments, drug users' unfamiliarity with health facilities, disconnect in communication with healthcare providers, and healthcare providers' lack of understanding of women's needs were factors that impede women's access to health services. Community-based services, comprising of outreach and drop-in centers mitigate these barriers by building trust, educating women on their health and rights, linking women to health facilities, sensitizing health providers on the needs of women who inject drugs, and integrating women's SRH services into community-based harm-reduction outreach. Inclusion of SRH services into community-based harm-reduction activities increased women's interest and access to harm-reduction interventions. These findings underscore the need to strengthen community-based programming for women who inject drugs, and to integrate SRH services into needle and syringe exchange programs.

Abstract
Women who use alcohol and drugs are often in their childbearing years, creating a need for integrated substance abuse and reproductive health services. However, our understanding of the social context and drivers of substance use during pregnancy, particularly in developing countries, is limited and largely unaddressed in clinical care. Our qualitative research explored the reproductive health of women of childbearing age who inject drugs and its implications for healthcare in Kisumu, Kenya. We used in-depth, semi-structured qualitative interviews with 17 women who inject drugs to explore reproductive health topics including knowledge, practices, and clinical interactions related to substance use during pregnancy. All but one woman had a prior pregnancy and two were pregnant during our study. Alcohol and drug use was prevalent throughout pregnancy, often described as a coping mechanism for stress. Women received mixed advice from family and social contacts regarding alcohol use during pregnancy, leading to differing perceptions of its health effects. Healthcare providers infrequently screened women for alcohol or drug use. Our analysis highlights the need for culturally appropriate alcohol and drug screening and counseling to be included in integrated reproductive health services in western Kenya.

Abstract
BACKGROUND Strong evidence supports the effectiveness of methadone-assisted therapy (MAT) to treat opioid dependence, reduce the risk of HIV transmission, and improve HIV related health outcomes among people who inject drugs (PWID). HIV prevalence reaches 71% in women who inject drugs (WWID) in Dar es Salaam, Tanzania; creating an urgent need for access to MAT. Despite the availability and potential benefits of treatment, few women have enrolled in services. This formative research sought to identify programmatic strategies to increase women's participation in outreach and their subsequent enrollment in MAT. METHODS We conducted twenty-five, in-depth interviews with patients and their providers at a MAT clinic. Open-ended interviews explored enrollment experiences, with a focus on contextual barriers and facilitators unique to women. Ethnographic observations of harm reduction education at outreach sites and the MAT clinic enriched interview data. Trust/mistrust emerged as an overarching theme cross cutting patient and provider accounts of the connective process to enroll PWID in the methadone program. We explore trust and mistrust in relationship to the interrelated themes of family loss, social isolation, vehement discrimination and motivation for treatment. RESULTS Narratives delineated both the generation of mistrust against PWID and the generation of mistrust in PWID against outsiders and medical institutions. In order to enroll PWID in treatment, community base organizations engaged outreach strategies to overcome mistrust and connect eligible patients to care, which varied in their success at recruiting women and men. Greater discrimination against WWID pushed them into hiding, away from outreach teams that focus on outdoor areas where men who inject drugs congregate. Building trust through multiple encounters and making a personal connection facilitated entry into care for women. Only PWID were eligible for MAT, due to resource constraints and the higher risk associated with injection drug use. Many women smoke heroin, yet still face high risk of HIV, resulting from low condom use during sex work to fund drug use. CONCLUSION Expanding outreach times and locations, by women peers, could increase women's enrollment in treatment. Allowing women who smoke heroin to enter the program could prevent onward transmission via sex work and reduce the chance of progressing from the lower risk smoking or sniffing to injection drug use.

Abstract
BACKGROUND Illegal drug markets are shaped by multiple forces, including local actors and broader economic, political, social, and criminal justice systems that intertwine to impact health and social wellbeing. Ethnographic analyses that interrogate multiple dimensions of drug markets may offer both applied and theoretical insights into drug use, particularly in developing nations where new markets and local patterns of use traditionally have not been well understood. This paper explores the emergent drug market in Kisumu, western Kenya, where our research team recently documented evidence of injection drug use. METHODS Our exploratory study of injection drug use was conducted in Kisumu from 2013 to 2014. We draw on 151 surveys, 29 in-depth interviews, and 8 months of ethnographic fieldwork to describe the drug market from the perspective of injectors, focusing on their perceptions of the market and reports of drug use therein. RESULTS Injectors described a dynamic market in which the availability of drugs and proliferation of injection drug use have taken on growing importance in Kisumu. In addition to reports of white and brown forms of heroin and concerns about drug adulteration in the market, we unexpectedly documented widespread perceptions of cocaine availability and injection in Kisumu. Examining price data and socio-pharmacological experiences of cocaine injection left us with unconfirmed evidence of its existence, but opened further possibilities about how the chaos of new drug markets and diffusion of injection-related beliefs and practices may lend insight into the sociopolitical context of western Kenya. CONCLUSIONS We suggest a need for expanded drug surveillance, education and programming responsive to local conditions, and further ethnographic inquiry into the social meanings of emergent drug markets in Kenya and across sub-Saharan Africa.

Abstract
Heroin trafficking and consumption has increased steadily over the past decade in Tanzania, but limited information regarding HIV and drug use exists for the city of Mwanza. Our study investigates the epidemiology of drug use, and HIV risk behaviors among drug users in the northwestern city of Mwanza. Using a combination of targeted sampling and participant referral, we recruited 480 participants in Mwanza between June and August 2014. The sample was 92% male. Seventy-nine (16.4%) participants reported injecting heroin, while 434 (90.4%) reported smoking heroin. Unstable housing and cohabitation status were the only socioeconomic characteristics significantly associated with heroin injection. More than half of heroin injectors left syringes in common locations, and half reported sharing needles and syringes. Other risk behaviors such as lack of condom use during sex, and the use of illicit drugs during sex was widely reported as well. Among the study sample, there was poor awareness of health risks posed by needle/syringe sharing and drug use. Our results show that heroin use and HIV risk related behaviors are pressing problems that should not be ignored in Mwanza. Harm reduction programs are urgently needed in this population.

Abstract
Contrary to popular belief, policies on drug use are not always based on scientific evidence or composed in a rational manner. Rather, decisions concerning drug policies reflect the negotiation of actors' ambitions, values, and facts as they organize in different ways around the perceived problems associated with illicit drug use. Drug policy is thus best represented as a complex adaptive system (CAS) that is dynamic, self-organizing, and coevolving. In this analysis, we use a CAS framework to examine how harm reduction emerged around heroin trafficking and use in Tanzania over the past thirty years (1985-present). This account is an organizational ethnography based on of the observant participation of the authors as actors within this system. We review the dynamic history and self-organizing nature of harm reduction, noting how interactions among system actors and components have coevolved with patterns of heroin us, policing, and treatment activities over time. Using a CAS framework, we describe harm reduction as a complex process where ambitions, values, facts, and technologies interact in the Tanzanian sociopolitical environment. We review the dynamic history and self-organizing nature of heroin policies, noting how the interactions within and between competing prohibitionist and harm reduction policies have changed with patterns of heroin use, policing, and treatment activities over time. Actors learn from their experiences to organize with other actors, align their values and facts, and implement new policies. Using a CAS approach provides researchers and policy actors a better understanding of patterns and intricacies in drug policy. This knowledge of how the system works can help improve the policy process through adaptive action to introduce new actors, different ideas, and avenues for communication into the system.

Abstract
Injecting drug use is a growing problem in Africa and a growing risk factor for contracting HIV in the region. It is imperative that HIV research includes injecting drug users so that they too are able to benefit from safe and effective behavioural interventions and biomedical HIV prevention and treatment products. This article relates a critical review of the findings of a desk review of previously published literature. The article examines injecting drug use in relation to HIV-related risk and research in Kenya, Mauritius, Nigeria, South Africa and Tanzania. The ethical challenges of including people who inject drugs in HIV research in Africa are also presented. The review found injecting drug use to be on the increase in all the countries reviewed. HIV-risk behaviour among people who inject drugs, such as needle-sharing and higher-risk sexual behaviour, was also found to be widespread. Furthermore, criminalisation of drug use and strict anti-drug laws are common in the countries reviewed, while harm-reduction programmes for people who inject drugs were found to be limited. The review identified a number of ethical challenges to the involvement of people who inject drugs in HIV research in Africa. This includes the illegal status and stigma surrounding injecting drug use, which may complicate participant recruitment, enrolment and retention. In addition, a lack of funding for supportive programmes to help injecting drug users may hinder the provision of appropriate standards of prevention and care and treatment for those who seroconvert.

Abstract
Epidemiological data in Vietnam shows high HIV prevalence rates among injection drug users, especially in urban centres. However, there are limited data on specific practices used to prepare and inject drugs or on sexual practices among Vietnamese injectors. A street-based cross-sectional interview was conducted with 862 heroin injectors in Hanoi, Vietnam, to collect such data. Variability was seen in both injection and sexual risk, with 12.9% of current injectors reporting at least one unsafe method of drug sharing and 57.1% reporting unsafe sex in the past 30 days. These risks were strongly associated with those who engaged in unsafe injection significantly more likely to engage in unsafe sex (69.4% vs. 55.3%) and those engaging in unsafe sex significantly more likely to engage in unsafe injection (15.7% vs. 9.2%). These findings highlight the overlap of injection and sexual risk practices among Vietnamese heroin users and suggest the need for strong, broadly targeted HIV prevention activities among this population.

Abstract
Over the past decade, the amount and variety of addiction research around the world has increased substantially. Researchers in Australia, Canada, United Kingdom, United States, and western Europe have significantly contributed to knowledge about addiction and its treatment. However, the nature and context of substance use disorders and the populations using drugs are far more diverse than is reflected in studies done in Western cultures. To stimulate new research from a diverse set of cultural perspectives, the National Institute on Drug Abuse (NIDA) has promoted the development of addiction research capacity and skills around the world for over 25 years. This review will describe the programs NIDA has developed to sponsor international research and research fellows and will provide some examples of the work NIDA has supported. NIDA fellowships have allowed 496 individuals from 96 countries to be trained in addiction research. The United Arab Emirates and Saudi Arabia have recently developed funding to support addiction research to study, with advice from NIDA, the substance use disorder problems that affect their societies. Examples from Malaysia, Tanzania, Brazil, Russian Federation, Ukraine, Republic of Georgia, Iceland, China, and Vietnam are used to illustrate research being conducted with NIDA support. Health services research, collaboratively funded by the U.S. National Institutes of Health and Department of State, addresses a range of addiction service development questions in low- and middle-income countries. Findings have expanded the understanding of addiction and its treatment, and are enhancing the ability of practitioners and policy makers to address substance use disorders.

Abstract
There is a dearth of evidence on injection drug use and associated HIV infections in Kenya. To generate population-based estimates of characteristics and HIV/STI prevalence among people who inject drugs (PWID) in Nairobi, a cross-sectional study was conducted with 269 PWID using respondent-driven sampling. PWID were predominantly male (92.5 %). An estimated 67.3 % engaged in at least one risky injection practice in a typical month. HIV prevalence was 18.7 % (95 % CI 12.3–26.7), while STI prevalence was lower [syphilis: 1.7 % (95 % CI 0.2–6.0); gonorrhea: 1.5 % (95 % CI 0.1–4.9); and Chlamydia: 4.2 % (95 % CI 1.2–7.8)]. HIV infection was associated with being female (aOR, 3.5; p = 0.048), having first injected drugs 5 or more years ago (aOR, 4.3; p = 0.002), and ever having practiced receptive syringe sharing (aOR, 6.2; p = 0.001). Comprehensive harm reduction programs tailored toward PWID and their sex partners must be fully implemented as part of Kenya’s national HIV prevention strategy.

Abstract
BACKGROUND Women who use drugs, irrespective of whether these are injected or not, are faced with multiple issues which enhance their vulnerability to HIV. METHODS In this commentary, we explore the HIV risks and vulnerabilities of women who use drugs as well as the interventions that have been shown to reduce their susceptibility to HIV infection. RESULTS Women who inject drugs are among the most vulnerable to HIV through both unsafe injections and unprotected sex. They are also among the most hidden affected populations, as they are more stigmatized than their male counterparts. Many sell sex to finance their own and their partner's drug habit and often their partner exerts a significant amount of control over their sex work, condom use and injection practices. Women who use drugs all over the world face many different barriers to HIV service access including police harassment, judgmental health personnel and a fear of losing their children. CONCLUSION In order to enable these women to access life-saving services including needle-syringe and condom programs, opioid substitution therapy and HIV testing and treatment, it is essential to create a conducive environment and provide tailor-made services that are adapted to their specific needs.

Abstract
BACKGROUND People who inject drugs (PWID) in Dar es Salaam, Tanzania, have an estimated human immunodeficiency virus (HIV) prevalence of 42%-50% compared with 6.9% among the general population. Extensive evidence supports methadone maintenance to lower morbidity, mortality, and transmission of HIV and other infectious diseases among PWID. In 2011, the Tanzanian government launched the first publicly funded methadone clinic on the mainland of sub-Saharan Africa at Muhimbili National Hospital. METHODS We conducted a retrospective cohort study of methadone-naive patients enrolling into methadone maintenance treatment. Kaplan-Meier survival curves were constructed to assess retention probability. Proportional hazards regression models were used to evaluate the association of characteristics with attrition from the methadone program. RESULTS Overall, 629 PWID enrolled into methadone treatment during the study. At 12 months, the proportion of clients retained in care was 57% (95% confidence interval [CI], 53%-62%). Compared with those receiving a low dose (<40 mg), clients receiving a medium (40-85 mg) (adjusted hazard ratio [aHR], 0.50 [95% CI, .37-.68]) and high (>85 mg) (aHR, 0.41 [95% CI, .29-.59]) dose of methadone had a lower likelihood of attrition, adjusting for other characteristics. Older clients (aHR, 0.53 per 10 years [95% CI, .42-.69]) and female clients (aHR, 0.50 [95% CI, .28-.90]) had a significantly lower likelihood of attrition, whereas clients who reported a history of sexual abuse (aHR, 2.84 [95% CI, 1.24-6.51]) had a significantly higher likelihood of attrition. CONCLUSIONS Patient retention in methadone maintenance is comparable to estimates from programs in North America, Europe, and Asia. Future implementation strategies should focus on higher doses and flexible dosing strategies to optimize program retention and strengthened efforts for clients at higher risk of attrition.

Abstract
BACKGROUND Transmission of HIV from intra-venous drug users (IDUs) to the community occurs predominantly through high-risk sexual behaviors. Limited information exists regarding the high-risk sexual behaviors of IDUs in Iran. AIM The aim of this study was to determine the prevalence and factors associated with having multiple sexual partners among Iranian IDUs. METHODS This is a national survey on drug-dependent adults. Participants were sampled from medical centers, prisons, and streets of capitals of 29 provinces in Iran between May 2007 and February 2008. We analyzed data of 1416 current IDUs. Socio-demographics and drug use characteristics were entered into a binary logistic regression model to determine predictors of having multiple sexual partners. RESULTS Having multiple sexual partners in the past or at the time of survey was reported by 56.4% of Iranian IDUs. Multivariate analysis showed that the likelihood of having multiple sexual partners in IDUs decreased by being married [odds ratio (OR), 0.38; P < 0.001] and increased by female gender (OR, 13.44; P = 0.02), having illegal income (OR, 1.72; P = 0.003), higher monthly family income (OR, 1.01; P = 0.003), pleasure, curiosity, and recreation as cause of first drug use (OR, 1.37; P = 0.04), ruins as usual place for injection (OR, 1.89; P = 0.001) and history of syringe sharing (OR, 1.50; P = 0.02). CONCLUSION Having multiple sexual partners was reported by majority of Iranian IDUs, and this was linked to socio-demographics, initiation data, and other risk behaviors. This information should be considered in prevention efforts to reduce sexual transmission of HIV infection in Iran.

Identifying programmatic gaps: inequities in harm reduction service utilization among male and female drug users in Dar es Salaam, Tanzania. PLoS One 2013; 8:e67062. [PMID: 23825620 PMCID: PMC3692420 DOI: 10.1371/journal.pone.0067062] [Citation(s) in RCA: 56] [Impact Index Per Article: 5.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/29/2012] [Accepted: 05/14/2013] [Indexed: 11/19/2022] Open
Abstract
Introduction Current estimates suggest an HIV prevalence of 42% among people who inject drugs (PWIDs) in Dar es Salaam, while HIV prevalence is estimated to be 8.8% among the general population in the city. To address the HIV epidemic in this population, the government of Tanzania began establishing HIV prevention, treatment and care services including outreach and medication assisted treatment (MAT) for PWIDs in 2010. We assessed gender inequities in utilization of outreach and MAT services and evaluated differences in HIV risk behaviors between female and male PWIDs. Materials and Methods Routine outreach data between December 2010 to mid-August 2012 and baseline data on clients enrolling in methadone from February 2011 to August 2012 were utilized. Binomial regression was used to estimate adjusted relative risk estimates comparing females to males. Results From December 2010 to August 2012, 8,578 contacts were made to drug users; among them 1,898 were injectors. A total of 453 injectors were eligible and referred to MAT, of which, 443 enrolled in treatment. However, regarding total outreach contacts, outreach to PWID, referral to MAT and enrollment in MAT, 8% or less of drug users accessing services were women. In contrast, weighted estimations from surveys suggest that 34% of PWIDs are female, and this approximation is similar to recent population size estimations. Overall, 43% of traditional outreach workers conducting outreach with drug users were female. Though reporting higher levels of condom usage, female PWID were more likely to report multiple sex partners, anal sex, commercial sex work and struggle under a higher burden of addiction, mental disorders and abuse. Conclusions Services have not been mobilized adequately to address the clear needs of females who inject drugs. A clear and urgent need exists for women-centered strategies that effectively engage female PWID into HIV prevention services.

Abstract
In the past decade, Tanzania has seen a rapid rise in the number of people who inject drugs (PWID), specifically heroin. While the overall HIV prevalence in Tanzania has declined recently to 5.6%, in 2009, the HIV prevalence among PWID remains alarmingly high at 35%. In this paper, we describe how the Tanzania AIDS Prevention Program (TAPP), Médecins du Monde France (MdM-F), and other organisations have been at the forefront of addressing this public health issue in Africa, implementing a wide array of harm reduction interventions including medication-assisted treatment (MAT), needle and syringe programs (NSP), and “sober houses” for residential treatment in the capital, Dar es Salaam, and in Zanzibar. Looking toward the future, we discuss the need to (1) extend existing services and programs to reach more PWID and others at risk for HIV, (2) develop additional programs to strengthen existing programs, and (3) expand activities to include structural interventions to address vulnerabilities that increase HIV risk for all Tanzanians.

Abstract
OBJECTIVE Injecting drug use is now recognized as a significant risk factor for HIV in sub-Saharan Africa. We evaluated prevalence and correlates of HIV among injecting drug users (IDUs) in Nigeria. METHODS A cross sectional design using respondent driven sampling was conducted in six states in 2010. Weighted HIV prevalence and injecting risk behaviors calculated using RDS analytic tool. Logistic regression was used to determine correlates of HIV infection, stratified by state. RESULTS Total numbers of IDUs ranged from 197 in Lagos to 273 in Cross River and Oyo states. HIV prevalence was highest in Federal Capital Territory (FCT) at 9.3%, Kaduna 5.8%, Oyo 5.1%, Kano 4.9%, CR 3.3% and Lagos 3.0%. Although >90% of participants were male, females had higher HIV prevalence in all states surveyed except FCT (range: 7.4% in CR to 37.7% in Kano). Logistic regression showed that females were significantly more likely to be HIV positive in Kano [OR=33.2, 95% CI: 6.8-160.4], Oyo [AOR=15.9, 95% CI: 3.69-68.51], Lagos [OR=15.5, 95% CI: 2.41-99.5] and Kaduna states [AOR=19.6, 95% CI: 4.4-87.6]. For injecting risk behavior, only receptive sharing was associated with HIV [AOR=7.6, 95% CI: 1.2-48.7] and [AOR=0.2, 95% CI: 0.04-0.92] in Oyo and Kaduna states respectively. CONCLUSIONS Considerable heterogeneity in the prevalence of HIV and associated risk behaviors exist among IDUs across Nigeria. Females had higher HIV prevalence among IDUs in five of six states, suggesting a need for targeted interventions for this hidden subgroup. Further research is needed to understand HIV transmission dynamics of IDUs in Nigeria. Community-based opioid substitution therapy and needle exchange programs should be implemented without delay.

Abstract
Drug use in Kenya dates back to the precolonial period but research among drug users in relation to human immunodeficiency virus (HIV)-associated risk and intervention strategies has been low. To evaluate HIV-1 diversity and drug resistance among injecting drug users (IDUs), a cross-sectional study involving 58 patients was carried out in Mombasa between February and March 2010. HIV-1 RNA was extracted from plasma and polymerase chain reaction using specific primers for HIV-1 reverse transcriptase was done. Population sequencing was done and subtypes were determined phylogenetically. The prevalent HIV-1 subtypes were A1 (52/58), D (5/58), and C (2/58). The prevalence of drug resistance was 13.8% (8/58) with detection of nucleoside reverse transcriptase inhibitor (NRTI) mutations, T215F (n=5), K219Q (n=3), M184V (n=1), and nonnucleoside RTI mutation, K103N (n=1). Antiretroviral therapy (ART) and its monitoring among infected Kenyan IDUs is feasible. Policymakers and service providers in HIV prevention initiatives should improve service delivery so as to measure ART coverage among IDUs to prevent further transmission of drug-resistant variants.

Abstract
Dramatic rises in injection drug use (IDU) in sub-Saharan Africa account for increasingly more infections in a region already overwhelmed by the HIV epidemic. There is no known estimate of the number of people who inject drugs (PWID) in the region, or the associated HIV prevalence in PWID. We reviewed literature with the goal of describing high-risk practices and exposures in PWID in sub-Saharan Africa, as well as current HIV prevention activities aimed at drug use. The literature search looked for articles related to HIV risk, injection drug users, stigma, and HIV testing in sub-Saharan Africa. This review found evidence demonstrating high rates of HIV in IDU populations in sub-Saharan Africa, high-risk behaviors of the populations, lack of knowledge regarding HIV, and low HIV testing uptake. There is an urgent need for action to address IDU in order to maintain recent decreases in the spread of HIV in sub-Saharan Africa.

Abstract
AIMS This study examined the association between the blood-sharing practice of 'flashblood' use and demographic factors, human immunodeficiency virus (HIV) status and variables associated with risky sex and drug behaviors among female injecting drug users. Flashblood is a syringe-full of blood passed from someone who has just injected heroin to someone else who injects it in lieu of heroin. DESIGN A cross-sectional study. SETTING Dar es Salaam, Tanzania. PARTICIPANTS One hundred and sixty-nine female injecting drug users (IDUs) were recruited using purposive sampling for hard-to-reach populations. MEASUREMENTS The association between flashblood use, demographic and personal characteristics and risky sex and drug use variables was analyzed by t-test and chi(2) test. The association between flashblood use and residential neighborhood was mapped. FINDINGS Flashblood users were more likely to: be married (P = 0.05), have lived in the current housing situation for a shorter time (P < 0.000), have been forced as a child to have sex by a family member (P = 0.007), inject heroin more in the last 30 days (P = 0.005), smoke marijuana at an earlier age (P = 0.04), use contaminated rinse-water (P < 0.03), pool money for drugs (P < 0.03) and share drugs (P = 0.000). Non-flashblood users were more likely to live with their parents (P = 0.003). Neighborhood flashblood use was highest near downtown and in the next two adjoining suburbs and lowest in the most distant suburbs. CONCLUSIONS These data indicate that more vulnerable women who are heavy users and living in shorter-term housing are injecting flashblood. The practice of flashblood appears to be spreading from the inner city to the suburbs.

Abstract
Injection drug use has recently emerged in sub-Saharan Africa. The purpose of this study was to assess the factors associated with increased risk of testing HIV-positive in a sample of injection drug users (IDUs) in Dar es Salaam, Tanzania. Participants were recruited by a trained outreach worker or were referred by IDUs who had completed the study. Blood specimens and self-reported socioeconomic and behavioral data were collected from 315 male and 219 female IDUs. Data were analyzed using univariate odds ratios and multivariate logistic regression modeling. Forty-two percent of the sample tested HIV-positive. Several socioeconomic, injection, and sexual factors were found to be associated with increased odds of testing HIV-positive. Multivariate analysis showed that having had sex more than 81 times in past 30 days, earning less than 100,000 shillings (US$76) in the past month, residency in Dar es Salaam for less than 5 years, and injecting for 3 years were independently associated with the greatest risk of infection. The rate of HIV infection in this sample of IDUs was found to be very high, suggesting that injection drug use may be a factor in the continuing epidemic in sub-Saharan Africa. The factors associated with increased risk of HIV infection suggest further research is needed on the needle use and sexual networks of IDUs.

Abstract
The reuse of injecting equipment in clinical settings is well documented in Africa and appears to play a substantial role in generalized HIV epidemics. The U.S. and the WHO have begun to support large scale injection safety interventions, increased professional education and training programs, and the development and wider dissemination of infection control guidelines. Several African governments have also taken steps to control injecting equipment, including banning syringes that can be reused.However injection drug use (IDU), of heroin and stimulants, is a growing risk factor for acquiring HIV in the region. IDU is increasingly common among young adults in sub-Saharan Africa and is associated with high risk sex, thus linking IDU to the already well established and concentrated generalized HIV epidemics in the region. Demand reduction programs based on effective substance use education and drug treatment services are very limited, and imprisonment is more common than access to drug treatment services.Drug policies are still very punitive and there is widespread misunderstanding of and hostility to harm reduction programs e.g. needle exchange programs are almost non-existent in the region. Among injection drug users and among drug treatment patients in Africa, knowledge that needle sharing and syringe reuse transmit HIV is still very limited, in contrast with the more successfully instilled knowledge that HIV is transmitted sexually. These new injection risks will take on increased epidemiological significance over the coming decade and will require much more attention by African nations to the range of effective harm reduction tools now available in Europe, Asia, and North America.

Abstract
BACKGROUND Injecting drug users (IDU) are at increased risk of human immunodeficiency virus (HIV) infection. Their HIV prevalence however varies from place to place and may not be directly linked with the level of individual risk. This study explores the relative importance of individual and community level characteristics in the practice of HIV-related risk behaviors in IDU in Hong Kong where the HIV prevalence has remained low at below 1%. METHODS Methadone clinics were used as the channel for accessing drug users in Hong Kong. HIV-related risk factors in drug users attending these clinics were retrieved from a questionnaire routinely administered to newly admitted and readmitted clients, and assessed using logistic regression and multilevel analyses. RESULTS Between 1999 and 2005, a total of 41,196 person-admissions were recorded by 20 methadone clinics. Male gender, older age and new admissions in bigger clinics located in districts with older median age were more likely to have engaged in HIV related risk behaviors including heroin injection, needle sharing, unprotected sex and having multiple sex partners (p < 0.05). CONCLUSION Multilevel analysis is a useful adjunct for determining the association between risk behaviors and both individual and community factors in IDUs, which can be demonstrated even in low HIV prevalence settings.

Abstract
We describe receptive and distributive needle/syringe sharing among injection drug users (IDUs) in Kabul, Afghanistan. In this cross-sectional study, IDUs completed an interviewer-administered questionnaire. Logistic regression identified correlates of needle sharing in the last six months. Receptive and distributive sharing in the last six months were reported by 28.2% and 28.7% of participants, respectively, and were both independently associated with reported difficulty obtaining new syringes (Receptive sharing: AOR = 2.60, 95% CI: 1.66-4.06; Distributive: AOR = 1.56, 95% CI: 1.02-2.39). Receptive and distributive sharing are common among IDU in Kabul; scaling up availability of sterile, no-cost injecting equipment is urgently needed.
