Objectives:This study aimed to identify social, economic, structural, and individual-level vulnerabilities of female adolescents who sell sex in Kumasi, Ghana. Methods:Twenty-four in-depth interviews and 4 focus group discussions were conducted with female sex workers of age 18–20 years who had been involved in sex work for at least 2 years. Total sample size was 48. Findings:One-third of participants started sex work before age 15. Knowledge of HIV was accurate and most reported having intentions to use condoms consistently with clients; however, factors such as higher payments, drug and/or alcohol use, fear of violence, and police harassment affected condom use. They perceived violence and rape at the hands of clients as their greatest risk. They also reported abuse and exploitation by police. Respondents voiced strong concerns that girls and teens involved in sex work are at higher risk of unsafe sex, exploitation, and abuse than their older and more experienced counterparts. Unprotected sex with boyfriends was also common. Discussion:The pathway to sex work followed a similar pattern for many study participants who left their rural homes for Kumasi in search of economic opportunity. While adolescents who sell sex appear to be abundant in Kumasi, they have been missed by HIV prevention and harm reduction programming. The findings from this study informed the design and implementation of a young female sex worker peer educator pilot program. Key elements of that program are presented, and recommendations for future program evaluation are made.

Background:Female sex workers (FSWs) in Ghana have a 10-fold greater risk for acquiring HIV than the general adult population, and they contribute a substantial proportion of the new HIV infections in the country. Although researchers have conducted behavioral and biological surveys, there has been no review of the contextual, programmatic, and epidemiological changes over time. Methods:The authors conducted a historical review of HIV prevention programs in Ghana. We reviewed the use of different interventions for HIV prevention among FSWs and data from program monitoring and Integrated Biological and Behavioral Surveillance Surveys. In particular, we looked at changes in service access and coverage, the use of HIV testing and counseling services, and the changing prevalence of HIV and other sexually transmitted infections. Results:HIV prevention interventions among FSWs increased greatly between 1987 and 2013. Only 72 FSWs were reached in a pilot program in 1987, whereas 40,508 FSWs were reached during a national program in 2013. Annual condom sales and the proportion of FSWs who used HIV testing and counseling services increased significantly, whereas the prevalence of gonorrhea and chlamydia decreased. The representation of FSWs in national HIV strategic plans and guidelines also improved. Conclusions:Ghana offers an important historical example of an evolving HIV prevention program that—despite periods of inactivity—grew in breadth and coverage over time. The prevention of HIV infections among sex workers has gained momentum in recent years through the efforts of the national government and its partners—a trend that is critically important to Ghanas future.

Background Adherence to prevention, care, and treatment recommendations among people living with HIV (PLHIV) is a critical challenge. Yet good clinical outcomes depend on consistent, high adherence to antiretroviral therapy (ART) regimens. Mobile phones offer a promising means to improve patient adherence and health outcomes. However, limited information exists on the impact that mobile phones for health (mHealth) programs have on ART adherence or the behavior change processes through which such interventions may improve patient health, particularly among ongoing clients enrolled in large public sector HIV service delivery programs and key populations such as men who have sex with men (MSM) and female sex workers (FSW). Objective Our aim is to evaluate an mHealth intervention where text message reminders are used as supportive tools for health providers and as motivators and reminders for ART clients to adhere to treatment and remain linked to care in Ghana. Using an implementation science framework, we seek to: (1) evaluate mHealth intervention effects on patient adherence and health outcomes, (2) examine the delivery of the mHealth intervention for improving HIV care and treatment, and (3) assess the cost-effectiveness of the mHealth intervention. Methods The 36-month study will use a facility cluster randomized controlled design (intervention vs standard of care) for evaluating the impact of mHealth on HIV care and treatment. Specifically, we will look at ART adherence, HIV viral load, retention in care, and condom use at 6 and 12-month follow-up. In addition, participant adoption and satisfaction with the program will be measured. This robust methodology will be complemented by qualitative interviews to obtain feedback on the motivational qualities of the program and benefits and challenges of delivery, especially for key populations. Cost-effectiveness will be assessed using incremental cost-effectiveness ratios, with health effects expressed in terms of viral load suppression and costs of resources used for the intervention. Results This study and protocol was fully funded, but it was terminated prior to review from ethics boards and study implementation. Conclusions This cluster-RCT would have provided insights into the health effects, motivational qualities, and cost-effectiveness of mHealth interventions for PLHIV in public sector settings. We are seeking funding from alternate sources to implement the trial.

Background: Research suggests that men who have sex with men (MSM) often engage in high-risk sex and use illicit substances. Objective: To increase understanding of HIV knowledge and vulnerability among adolescent and young adult MSM, with a focus on alcohol and drug use and transactional sex. Methods: We conducted in-depth interviews and Focus Group Discussions (FGDs) with adolescent (aged 15-17 years) and young adult (aged 18-29 years) MSM in Kumasi, Ghana. MSM who reported recent alcohol and/or substance use or engagement in transactional sex were eligible. Questions covered HIV-related knowledge, experiences with substance-use and transactional sex, and attitudes regarding sexual risk-taking and HIV-related services. Data were analyzed thematically using NVivo 10.0 software. Results: Ninety-nine MSM participated in 44 interviews and 8 FGDs. Most were attending or had completed secondary school. HIV knowledge was high, but with major gaps. Most consumed alcohol; one-fourth used drugs. Alcohol and substances were consumed to enhance pleasure during sex with another man. Transactional sex was common and positively viewed. Half of the participants used condoms inconsistently or never, and self-perceived HIV risk was high. Nearly half faced stigma-related barriers to accessing HIV-related services. Conclusion: As Ghana strives to achieve the UNAIDS’s 90-90-90 global targets (90% of people living with HIV know their status, 90% who know their status are on sustained treatment, and 90% of those on treatment are virally suppressed), we recommend enhancing MSM-targeted prevention programs, improving care options, and increasing use of critical clinical HIV-services by ensuring that MSM receive unbiased, confidential care.

Abstract Little is known about female sex workers’ daily lives or emotional relationships. Using relational-cultural theory, this study explored the relationship dynamics between sex workers and their intimate partners in Kumasi, Ghana. We collected qualitative data from 37 male intimate partners through 24 in-depth interviews and two focus group discussions (FGDs) with 13 male partners. We also conducted three FGDs with 20 women involved in sex work. Relationships between sex workers and their intimate partners were mutual, reciprocal and transactional. Male partners provided protection for financial support, a place to sleep and intimacy. Both men and women described their relationships in terms of friendship, love and a hopeful future. Women were reluctant to quit sex work because they depended on it for income. Most respondents did not use condoms in these romantic relationships, citing trust, love, faithfulness and commitment. Both men and women described high levels of violence in their relationships. The context of sex work heightens vulnerability but also appears to facilitate resilience and creative coping strategies. The relational dynamics between sex workers and their intimate partners in Ghana merit further exploration to examine the extent to which women involved in sex work hold and exert power within these relationships.

ABSTRACT Young key populations (ages 10–24) (YKPs) are uniquely vulnerable to HIV infection. Yet they are often underserved, due in part to a limited understanding of their needs. Many successful approaches to understanding YKPs exist but are not widely used. To identify the most useful approaches and encourage their uptake, we reviewed strategic information on YKPs and experiences collecting, analysing, and utilising it from countries in Africa, Asia, and Central and Eastern Europe. As a result, we recommend one central guiding principle – any effort to understand and serve YKPs should include a specific focus on adolescent key populations (AKPs) (ages 10–19) – and three strategies to inform data collection, analysis, and use: tailor recruitment practices to ensure young people’s representation, select indicators and research methods based on their ability to inform responsive programming for and give a voice to YKPs, and thoroughly disaggregate data. We demonstrate the utility of each strategy in YKP research and programmes, and in doing so note the particular importance for AKPs. We hope that this paper encourages additional research on YKPs and helps bridge the gap between research and effective programmes to serve the youngest and most vulnerable members of key populations.

Background This qualitative study was designed to examine vulnerability to HIV infection and health-related needs among young men who have sex with men (MSM) in Kumasi, Ghana. Study objectives were to explore substance use (SU) and transactional sex (TS), overlap between SU and TS, beliefs related to SU and TS, and HIV knowledge and risk behaviours in this population. Methods Adolescents (aged 15–17 years) and young adults (aged 18–29 years) who self-reported male-to-male sex in the previous 12 months and who either used alcohol or illicit substances or engaged in TS were recruited using snowball sampling. Data were collected through 44 in-depth interviews and eight focus group discussions, and analysed using QSR NVivo 10.0 software. Results A total of 99 MSM participated. Most reported engaging in alcohol use and TS; a minority used substances, mainly marijuana. The majority displayed knowledge of HIV transmission and prevention, though few understood the basics of HIV treatment. Most perceived they were at high risk of HIV infection due to inconsistent condom use. Their risky behaviours also encompassed group sex, multiple sexual partners, and SU. Most expressed specific health needs, including education, screening, and treatment for sexually transmitted infections. They reported having only one clinic that provides services specific to MSM, and requested shorter wait times at facilities. Barriers to health and HIV services access included stigmatisation, ill-treatment by providers, poor quality of services, fear of testing positive, and lack of privacy, health insurance, and not knowing where to access services. Participants suggested legalising male-to-male sex, educating the public about MSM, and providing MSM with jobs to alleviate their challenges. Conclusion Young MSM in Kumasi engage in high-risk behaviours and indicate a need for interventions to improve access to health and HIV-related services, increase HIV treatment knowledge, and reduce stigma among health providers and society.
