Sexual risk behaviours, condom use and sexually transmitted infection treatment-seeking behaviours among female sex workers and truck drivers in Uganda

Nearly half of adults with symptoms of sexually transmitted infections (STIs) did not seek clinical care: A population-based study of treatment-seeking behavior among adults in Rakai, Uganda

Understanding treatment-seeking behavior is critical to the treatment and control of sexually transmitted infections (STIs), yet current data on STI treatment seeking in low-resource settings is rare. This population-based study aimed to describe STI treatment-seeking behavior and identify factors associated with seeking treatment at a clinic among adults with STI-related symptoms in rural Uganda. The STI prevalence study (STIPS) conducted a survey and STI testing among all consenting adults aged 18-49 in two communities in rural south-central Uganda. Of 1,825 participants, 962 individuals self-reported STI symptoms in the past six months; we present descriptive data on treatment seeking and STI prevalence among these individuals. We used multivariable Poisson regressions with robust variance to determine the sociodemographic and symptom-related factors independently associated with seeking STI treatment at a clinic and assessed the association with previous clinic treatment seeking and current STI diagnosis. Forty-three percent of adults who reported STI-related symptoms in the past six months said they did not seek any treatment. Among those who did, 58% sought treatment at a private clinic, 28% at a government clinic, 9% at a pharmacy/drug store, 3% at a traditional healer, 2% at a market/shop, and 5% at another location. Among both males and females, having multiple STI related symptoms was positively associated with clinic treatment seeking (males = PRR: 1.73, 95%CI: 1.36-2.21; females = PR: 1.41, 95%CI: 1.12-1.78). Approximately one-third of males and females who reported previously seeking clinic treatment for their symptoms were diagnosed with a curable STI at the time of the survey. In this setting, nearly half of adults with STI-related symptoms are not seeking clinical care and many who report having sought treatment for recent STI symptoms have curable STIs. Future studies should explore barriers to care-seeking and strategies to improve STI services.

Examining Cash Expenditures and Associated HIV-Related Behaviors Using Financial Diaries in Women Employed by Sex Work in Rural Uganda: Findings from the Kyaterekera Study

BACKGROUND

Women employed by sex work (WESW) have a high risk of human immunodeficiency virus (HIV) infection and experience economic barriers in accessing care. However, few studies have described their financial lives and the relationship between expenditures and HIV-related behaviors.

METHODS

This exploratory study used financial diaries to collect expenditure and income data from WESW in Uganda over 6 months. Data were collected as part of a larger trial that tested the efficacy of an HIV prevention intervention method. Descriptive statistics were used to quantify women's income, relative expenditures, and negative cash balances. Bivariate and multivariate logistic regressions were used to examine the odds of sexual risk behavior or use of HIV medications for several cash scenarios.

RESULTS

A total of 163 WESW were enrolled; the participants mean age was 32 years old. Sex work was the sole source of employment for most WESW (99%); their average monthly income was $62.32. Food accounted for the highest proportion of spending (44%) followed by sex work (20%) and housing expenditures (11%). WESW spent the least on health care (5%). Expenditures accounted for a large but variable proportion of these women's income (56% to 101%). Most WESW (74%) experienced a negative cash balance. Some also reported high sex work (28%), health care (24%), and education (28%) costs. The prevalence of condomless sex (77%) and sex with drugs/alcohol (70%) was high compared to use of ART/PrEP (Antiretroviral therapy/Pre-exposure prophylaxis) medications (45%). Women's cash expenditures were not statistically significantly associated with HIV-related behaviors. However, the exploratory study observed a consistent null trend of lower odds of condomless sex (adjusted odds ratio (AOR) = 0.70, 95% confidence interval (CI): 0.28-1.70), sex with drugs/alcohol (AOR = 0.93, 95% CI: 0.42-2.05), and use of ART/PrEP (AOR = 0.80, 95% CI: 0.39-1.67) among women who experienced a negative cash balance versus those who did not. Similar trends were observed for other cash scenarios.

CONCLUSION

Financial diaries are a feasible tool to assess the economic lives of vulnerable women. Despite having paid work, most WESW encountered a myriad of financial challenges with limited spending on HIV prevention. Financial protections and additional income-generating activities may improve their status. More robust research is needed to understand the potentially complex relationship between income, expenditures, and HIV risk among vulnerable sex workers.

Factors influencing the use of multiple HIV prevention services among transport workers in a city in southwestern Uganda

The use of multiple HIV prevention services has been found to decrease the risk of acquiring HIV when tailored to individuals at risk of HIV exposure, including transport workers. Therefore, we assessed the uptake of multiple HIV prevention services (≥2) and associated factors among transport workers in a city in Southwestern Uganda. This cross-sectional study comprised motorcycle taxi riders, motor vehicle and truck drivers, aged 18 to 55 years who were selected and responded to an interviewer-administered questionnaire, between November 2021 and February 2022. Data was analyzed using descriptive statistical and modified Poisson regression analyses. Out of 420 participants, 97.6% were male, with a median age of 28 years and the majority were aged <34 years (84.6%). Overall, less than half (45.3%) of the participants had used multiple (≥2) HIV prevention services within a one-year period. Many participants had used condoms (32.2%) followed by voluntary HIV counseling and testing (27.1%), and safe male circumcision (17.3%). Most participants who tested for HIV had ever used condoms (16.2%), followed by those who received safe male circumcision and had ever used condoms (15%), and those who tested for HIV and had started on antiretroviral therapy (ART) (9.1%). In the adjusted model, factors that were significantly associated with the use of multiple HIV prevention services included religion (aPR = 1.25, 95% CI = 1.05-1.49), the number of concurrent sex partners (aPR = 1.33, 95% CI = 1.10-1.61), prior HIV testing and awareness of HIV serostatus (aPR = 0.55, 95% CI = 0.43-0.70), awareness of HIV prevention services (aPR = 2.49, 95% CI = 1.16-5.38), and financial payment to access HIV services (aPR = 2.27, 95% CI = 1.47-3.49). In conclusion, the uptake of multiple HIV prevention services among transport workers remains suboptimal. Additionally, individual behavioral factors influence the use of multiple HIV services compared with other factors. Therefore, differentiated strategies are needed to increase the utilization of HIV prevention services among transport workers.

Economic Abuse and Care-seeking Practices for HIV and Financial Support Services in Women Employed by Sex Work: A Cross-Sectional Baseline Assessment of a Clinical Trial Cohort in Uganda

Economic hardship is a driver of entry into sex work, which is associated with high HIV risk. Yet, little is known about economic abuse in women employed by sex work (WESW) and its relationship to uptake of HIV prevention and financial support services. This study used cross-sectional baseline data from a multisite, longitudinal clinical trial that tests the efficacy of adding economic empowerment to traditional HIV risk reduction education on HIV incidence in 542 WESW. Mixed effects logistic and linear regressions were used to examine associations in reported economic abuse by demographic characteristics, sexual behaviors, HIV care-seeking, and financial care-seeking. Mean age was 31.4 years. Most WESW were unmarried (74%) and had less than primary school education (64%). 48% had savings, and 72% had debt. 93% reported at least one economic abuse incident. Common incidents included being forced to ask for money (80%), having financial information kept from them (61%), and being forced to disclose how money was spent (56%). WESW also reported partners/relatives spending money needed for bills (45%), not paying bills (38%), threatening them to quit their job(s) (38%), and using physical violence when earning income (24%). Married/partnered WESW (OR = 2.68, 95% CI:1.60-4.48), those with debt (OR = 1.70, 95% CI:1.04-2.77), and those with sex-work bosses (OR = 1.90, 95% CI:1.07-3.38) had higher economic abuse. Condomless sex (β = +4.43, p < .05) was higher among WESW experiencing economic abuse, who also had lower odds of initiating PrEP (OR = .39, 95% CI:.17-.89). WESW experiencing economic abuse were also more likely to ask for cash among relatives (OR = 2.36, 95% CI:1.13-4.94) or banks (OR = 2.12, 95% CI:1.11-4.03). The high prevalence of HIV and economic abuse in WESW underscores the importance of integrating financial empowerment in HIV risk reduction interventions for WESW, including education about economic abuse and strategies to address it. Programs focusing on violence against women should also consider economic barriers to accessing HIV prevention services.

Preferences, beliefs, and attitudes about oral fluid and blood-based HIV self-testing among truck drivers in Kenya choosing not to test for HIV

Introduction

Clinical trials in sub-Saharan Africa support that HIV self-testing (HIVST) can increase testing rates in difficult-to-reach populations. However, trials mostly evaluate oral fluid HIVST only. We describe preferences for oral fluid vs. blood-based HIVST to elucidate prior trial results and inform testing programs.

Methods

Participants were recruited from a HIVST randomized controlled trial in Nakuru County, Kenya, which aimed to test the effect of choice between oral HIVST and facility-based testing compared to standard-of-care on HIV testing among truck drivers. We conducted in-depth interviews (IDIs) with purposively sampled trial participants who declined HIV testing at baseline or who were offered access to oral fluid HIVST and chose not to pick up the kit during follow-up. IDIs were conducted with all consenting participants. We first describe IDI participants compared to the other study participants, assessing the statistical significance of differences in characteristics between the two samples and then describe preferences, beliefs, and attitudes about HIVST biospecimen type expressed in the IDIs.

Results

The final sample consisted of 16 men who refused HIV testing at baseline and 8 men who did not test during follow-up. All IDI participants had tested prior to study participation; mean number of years since last HIV test was 1.55, vs. 0.98 among non-IDI participants (p = 0.093). Of the 14 participants who answered the question about preferred type of HIVST, nine preferred blood-based HIVST, and five, oral HIVST. Preference varied by study arm with four of five participants who answered this question in the Choice arm and five of nine in the SOC arm preferring blood-based HIVST. Six key themes characterized truckers' views about test type: (1) Rapidity of return of test results. (2) Pain and fear associated with finger prick. (3) Ease of use. (4) Trust in test results; (5) fear of infection by contamination; and (6) Concerns about HIVST kit storage and disposal.

Conclusion

We found no general pattern in the themes for preference for oral or blood-based HIVST, but if blood-based HIVST had been offered, some participants in the Choice arm might have chosen to self-test. Offering choices for HIVST could increase testing uptake.

Sexual practices, risk perception and HIV self-testing acceptability among long-distance truck drivers in Ekiti State, Nigeria

BACKGROUND

HIV/AIDS is a global health challenge with a high burden in sub-Saharan Africa. Long-distance drivers are a high-risk group whose assessment of HIV status, awareness and willingness to undergo HIV self-testing (HIVST) could help prevent the spread of HIV infections.

OBJECTIVE

This study examined the sexual practices, risk perception and HIVST acceptability among long-distance truck drivers in Ekiti State, Nigeria.

METHODS

A cross-sectional study was conducted among long-distance truck drivers between September 2019 and December 2019. A semi-structured questionnaire was designed to investigate the perceived sexual risk factors and willingness to undergo HIVST.

RESULTS

Of the 306 drivers that participated in the study, almost half (49.8%) had their first sexual experience before they turned 18 years. About one-third (38.6%) had multiple sex partners and (34.0%) patronised commercial sex workers in the past 6 months. Consistent use of condoms was reported in a negligible percentage (3.0%), while 7.4% used intravenous drugs. Two-thirds of the respondents were interested in HIVST, while 32.2% knew their HIV status. Significant factors associated with multiple sex partners were the duration of working as a long-distance truck driver and patronage of sex workers.

CONCLUSION

A significant proportion of the long-distance drivers were engaged in unsafe sexual practices and are at risk for HIV transmission. Considering the mobile nature of the long-distance drivers, the risky practices of these workers require intense advocacy, testing and treatment to reduce HIV transmission. Scaling-up testing using HIVST has the potential to bridge the gap in the diagnosis of HIV among long-distance drivers who are willing to be tested.

Regional heterogeneity in violence and individual characteristics associated with recent transactional sex among Ugandan girls and young women: A national and regional analysis of data from the Violence Against Children and Youth Survey

Objectives

This study assessed associations between recent transactional sex (TS) and potential determinants and variations in patterns across two geographic regions with high HIV burden compared to the rest of Uganda, among adolescent girls and young women (AGYW).

Methods

In 2015, a nationally representative cross-sectional household survey was conducted in Uganda. A stratified multi-stage cluster sample design produced nationally representative estimates and sub-national estimates for AGYW in two high HIV burden regions, DREAMS Central 1 (Bukomansimbi, Ssembabule, and Rakai districts) and DREAMS Central 2 (Mubende, Mityana, Gomba, and Mukono districts), and the rest of Uganda. To identify associations between recent TS (defined as sex in the past 12 months in exchange for material support or help) and risk factors, multivariable logistic regressions were conducted. Interaction terms assessed the associations between violence and recent TS across geographic regions.

Results

Nationally, 14.2% of sexually active AGYW engaged in recent TS. Region-specific significant associations emerged between recent TS and marriage, family wealth, friendship, orphanhood, and sexual debut. In DREAMS Central 1 and 2, AGYW who witnessed violence in the home or community, or experienced sexual, physical, or emotional violence had higher odds of recent TS than AGYW who did not experience that form of violence (adjusted odds ratio ranged between 2.10 (95% CI, 1.07, 4.13) and 8.25 (95% CI, 3.40, 20.06)). The magnitude of association between recent TS and types of violence varied by region.

Conclusions

Violence is strongly and consistently associated with recent TS, and patterns in prevalence and risk factors vary across regions in Uganda. Given the high risk of HIV association with recent TS, HIV epidemic control efforts may benefit from focus on comprehensive violence prevention and target persons who engage in TS. Comprehensive HIV prevention programming aimed at keeping AGYW HIV-negative should incorporate prevention of violence and TS as key components to facilitate HIV epidemic control in this vulnerable population.

Female Entertainment Workers and Condom Use Negotiation in Post-100% Condom Use Era Cambodia

Beyond the monopoly environment of the early 100% Condom Use Program in Cambodia, less is known about how current female entertainment workers negotiate condom use on their own, and what factors impact that negotiation. This study aims to understand the experiences of current female entertainment workers in negotiating condom use with clients in Cambodia. Data collection occurred over a period of 3 weeks (August-September 2017) with concurrent data transcription and translation. A total of 27 focus group discussions (FGDs) were conducted in the following groups: pilot FGD (5), karaoke bar (5), massage parlor (5), beer garden (5), on-call sex workers (3), cross-venue groups exploring parenting issues (2), and street-based sex workers (2). Female entertainment workers experience a range of control over negotiating condom use with clients. Participants reported times when they were able to take direct action and successfully insist on condom use, times when they agreed to participate in condomless sex for money in the face of economic insecurity, and times when male clients sabotaged their attempts to negotiate condom use with tricks, verbal threats or threats of violence. These experiences are influenced by alcohol use, economic shocks, trust between partners, and experiences with side effects. Our findings support the development of policies that re-invigorate the structural-level condom promotion programs while also acknowledging the many individual-level factors that shape condom use such as alcohol consumption, economic insecurity, trust, and side effects.

Preferences for Pre-exposure Prophylaxis Service Delivery Among Female Sex Workers in Malawi: A Discrete Choice Experiment

Female sex workers (FSW) in Malawi have among the highest HIV prevalence estimates worldwide. Daily oral pre-exposure prophylaxis (PrEP) is an effective HIV prevention method, yet preferences for PrEP delivery among FSW are lacking. Eight focus group discussions, a literature review, and cognitive interviews were conducted to identify modifiable PrEP delivery attributes and inform discrete-choice experiment (DCE) development for FSW in Lilongwe. Enrolled FSW received an interviewer-assisted DCE. Data were analyzed using mixed logit regression. Dispensing location was most preferred, followed by the provision of additional services. Women preferred receiving PrEP at family planning clinics or non-governmental organization run drop-in centers. Cervical cancer screening was the most preferred additional service, while pregnancy testing and partner risk reduction counseling were less valued. This study was the first study to examine PrEP delivery preferences in Malawi using DCE-a powerful elicitation tool to apply to other key populations at risk for HIV.

HIV control strategies for sex worker-client contact networks

Controlling the spread of HIV among hidden, high-risk populations such as survival sex workers and their clients is becoming increasingly important in the ongoing fight against HIV/AIDS. Several sociological and structural factors render general control strategies ineffective in these settings; instead, focused prevention, testing and treatment strategies which take into account the nature of survival sex work are required. Using a dynamic bipartite network model of sexual contacts, we investigate the optimal distribution of treatment and preventative resources among sex workers and their clients; specifically, we consider control strategies that randomly allocate antiretroviral therapy and pre-exposure prophylaxis within each subpopulation separately. Motivated by historical data from a South African mining community, three main asymmetries between sex workers and clients are considered in our model: relative population sizes, migration rates and partner distributions. We find that preventative interventions targeted at female sex workers are the lowest cost strategies for reducing HIV prevalence, since the sex workers form a smaller population and have, on average, more sexual contacts. However, the high migration rate among survival sex workers limits the extent to which prevalence can be reduced using this strategy. To achieve a further reduction in HIV prevalence, testing and treatment in the client population cannot be ignored.

A combination intervention addressing sexual risk-taking behaviors among vulnerable women in Uganda: study protocol for a cluster randomized clinical trial

BACKGROUND

Sub-Saharan Africa (SSA) has the highest number of people living with HIV/AIDS, with Nigeria, South Africa, and Uganda accounting for 48% of new infections. A systematic review of the HIV burden among women engaged in sex work (WESW) in 50 low- and middle-income countries found that they had increased odds of HIV infection relative to the general female population. Social structural factors, such as the sex work environment, violence, stigma, cultural issues, and criminalization of sex work are critical in shaping sexually transmitted infection (STI)/HIV risks among WESW and their clients in Uganda. Poverty is the most commonly cited reason for involvement in sex work in SSA. Against this backdrop, this study protocol describes a randomized controlled trial (RCT) that tests the impact of adding economic empowerment to traditional HIV risk reduction (HIVRR) to reduce new incidence of STIs and HIV among WESW in Rakai and the greater Masaka regions in Uganda.

METHODS

This three-arm RCT will evaluate the efficacy of adding savings, financial literacy and vocational training/mentorship to traditional HIVRR on reducing new incidence of STI infections among 990 WESW across 33 hotspots. The three arms (n = 330 each) are: 1) Control group: only HIVRR versus 2) Treatment group 1: HIVRR plus Savings plus Financial Literacy (HIVRR + S + FL); and 3) Treatment group 2: HIVRR plus S plus FL plus Vocational Skills Training and Mentorship (V) (HIVRR + S + FL + V). Data will be collected at baseline (pre-test), 6, 12, 18 and 24-months post-intervention initiation. This study will use an embedded experimental mixed methods design where qualitative data will be collected post-intervention across all conditions to explore participant experiences.

DISCUSSION

When WESW have access to more capital and/or alternative forms of employment and start earning formal income outside of sex work, they may be better able to improve their skills and employability for professional advancement, thereby reducing their STI/HIV risk. The study findings may advance our understanding of how best to implement gender-specific HIV prevention globally, engaging women across the HIV treatment cascade. Further, results will provide evidence for the intervention's efficacy to reduce STIs and inform implementation sustainability, including costs and cost-effectiveness.

Male partners of young women in Uganda: Understanding their relationships and use of HIV testing

BACKGROUND

Substantial concern exists about the high risk of sexually transmitted HIV to adolescent girls and young women (AGYW, ages 15-24) in Eastern and Southern Africa. Yet limited research has been conducted with AGYW's male sexual partners regarding their perspectives on relationships and strategies for mitigating HIV risk. We sought to fill this gap in order to inform the DREAMS Partnership and similar HIV prevention programs in Uganda.

METHODS

We conducted 94 in-depth interviews, from April-June 2017, with male partners of AGYW in three districts: Gulu, Mukono, and Sembabule. Men were recruited at community venues identified as potential transmission areas, and via female partners enrolled in DREAMS. Analyses focused on men's current and recent partnerships and HIV service use.

RESULTS

Most respondents (80%) were married and 28 years old on average. Men saw partner concurrency as pervasive, and half described their own current multiple partners. Having married in their early 20s, over time most men continued to seek out AGYW as new partners, regardless of their own age. Relationships were highly fluid, with casual short-term partnerships becoming more formalized, and more formalized partnerships characterized by periods of separation and outside partnerships. Nearly all men reported recent HIV testing and described testing at distinct relationship points (e.g., when deciding to continue a relationship/get married, or when reuniting with a partner after a separation). Testing often stemmed from distrust of partner behavior, and an HIV-negative status served to validate respondents' current relationship practices.

CONCLUSIONS

Across the three regions in Uganda, findings with partners of AGYW confirm earlier reports in Uganda of multiple concurrent partnerships, and demonstrate substantial HIV testing. Yet they also unearth the degree to which these partnerships are fluid (switching between casual and/or more long-term partnerships), which complicates potential HIV prevention strategies. Context-specific findings around these partnerships and risk are critical to further tailor HIV prevention programs.

Social and structural factors increase inconsistent condom use by sex workers' one-time and regular clients in Northern Uganda

While sex workers (SWs) bear the brunt of the epidemic in Uganda, there remains a dearth of empirical research on the structural drivers of HIV prevention among SWs. This study examined the drivers of inconsistent condom use by one-time and regular clients of young women SWs in Gulu, Northern Uganda. Data were drawn from the Gulu Sexual Health Study, a cross-sectional study of young SWs, aged 14 years and older (2011-2012). SWs were recruited using peer/SW-led outreach, in partnership with The AIDS Support Organization and other CBOs. Multivariable logistic regression was used to examine the correlates of inconsistent condom use by one-time and regular clients. In total, 84.5% of the 381 SWs servicing regular clients and 76.8% of the 393 SWs servicing one-time clients reported inconsistent client condom use. In multivariable analysis, physical/sexual violence by clients (AOR = 5.39; 95%CI 3.05-9.49), low sexual control by workers (measured by the validated Pulweritz scale) (AOR = 2.86; 95%CI 1.47-5.58), alcohol/drug use while working (AOR = 1.98; 95%CI 1.17-3.35) and migration to Gulu for sex work (AOR = 1.73; 95%CI 0.95-3.14) were positively correlated with inconsistent condom use by one-time clients. Correlates of inconsistent condom use by regular clients included: low sexual control by workers (AOR = 4.63; 95%CI 2.32-9.23); physical/sexual violence by clients (AOR = 3.48; 95%CI 1.85-6.53); police harassment (AOR = 2.57; 95%CI 1.17-5.65); and being a single mother (AOR = 2.07; 95%CI 1.09-3.93). Structural and interpersonal factors strongly influence inconsistent condom use by clients, with violence by clients and police, low sexual control by workers, migration and single-parenthood all linked to non-condom use. There is a need for peer-led structural interventions that improve access to occupational health and safety standards (e.g., violence prevention and alcohol/drug harm reduction policies/programming). Shifts away from the current punitive approaches towards SWs are integral to the success of such interventions, as they continue to undermine HIV prevention efforts.

Knowledge and Attitude About Sexually Transmitted Infections Amongst Truck Drivers in Southern Punjab, Pakistan

INTRODUCTION

There is very limited knowledge about sexually transmitted infections (STIs) transmission and prevention present amongst high-risk groups such as truck drivers in Pakistan because of lack of awareness and understanding about barrier techniques.

OBJECTIVE

The aim of this study was to collect and access the data gathered from truck drivers about symptoms of STIs, their attitude towards hazards of multiple sexual partners, homosexuality, transmission and consequences of STIs, and their perception about preventing it using condoms and other barrier methods.

METHODS

This study was conducted at small roadside tea stalls and local rest areas on Karachi road, Lodhran near the city of Bahawalpur in Southern Punjab, Pakistan. A structured questionnaire was designed, and 50 willing truck drivers of the city of Bahawalpur were included and interviewed. It was a cross-sectional study. Data was collected on knowledge about the STIs and use of barrier methods like condoms. Quantitative data was assessed and analyzed using SPSS version 23.0 (IBM, NY, USA).

RESULTS

Fifty truck drivers of Bahawalpur were interviewed via standardized questionnaire in this study. All of them provided answers about their knowledge of STIs. Twenty drivers (40%) reported burning micturition, and only two (four percent) knew the real cause of it. Thirty-two (64%) of them were well aware of the use of condoms. Thirty-eight (76%) truck drivers had the knowledge about the adverse effects of multiple sex partners.

CONCLUSION

The truck drivers of Bahawalpur city are quite vulnerable to STIs and this demonstrates the importance of prevention programs that can target this particular group. A significant number of the respondents had serious gaps in their knowledge about STIs like acquired immunodeficiency syndrome (AIDS), especially its modes of transmission, signs, and symptoms. The knowledge of other routes of human immunodeficiency virus (HIV) transmission like needle sharing and blood transfusion, and precautionary steps should be given due respect in HIV/AIDS awareness programs.

Prevalence of syphilis among female sex workers and their clients in Togo in 2011

BACKGROUND

During the last ten years, a resurgence of syphilis has occurred in many countries worldwide, including Togo. Previous studies have shown a wide range of syphilis infection among the female sex workers (FSWs), from 1.5 to 42.1%. In Togo, Key populations, including FSWs, are rarely involved in the sentinel surveillance programs to determine the prevalence of HIV and syphilis. The aim of this study was to determine the prevalence of syphilis among female sex workers (FSWs) and their clients in Togo.

METHODS

We conducted a cross-sectional study in December 2011 targeting FSWs and their clients in Togo. Among participant who consented, we collected blood samples for syphilis and HIV testing.

RESULTS

In total, 1,836 participants (1,106 FSWs and 730 clients) were included in the survey. Their mean age was 28.6 ± 9 years. The prevalence of syphilis was 2.2% (2.2% among FSWs compare to 2.3% among their clients, p = 0.82). This prevalence was higher among FSWs over 30 years old compare to those less than 30 years old (Odd Ratio (OR) =5.03; 95% CI [1.95-13.49]). Single FSWs were three times less likely to have syphilis than those living in couple or married (OR = 3.11; CI 95% [1.16-8.83]). Brothel based or declared FSWs were 4 times more likely to be infected by syphilis than secret ones (OR = 3.89; CI 95% [1.60-9.54]). Out of the 1,836 participants of the survey, 165 (8.9%) were HIV positive. Having syphilis was associated with HIV infection (OR = 3.41; IC 95% [1.53-7.41]).

CONCLUSION

This study showed that: i) the prevalence of syphilis among FSWs and their clients was high; ii) syphilis was significantly associated with HIV infection. It is necessary to increase awareness campaigns and emphasize on condom use among this key population group.

Social and structural factors related to HIV risk among truck drivers passing through the Iringa region of Tanzania

Truck drivers and their assistants have been identified as groups at higher risk for HIV infection. We sought to identify and describe the social and structural factors that may contribute to HIV risk among truck drivers who visit rest stops in Iringa, Tanzania, a region characterized by high levels of migration and mobility. This analysis was part of a comprehensive strategic assessment to examine HIV risk factors in Iringa. This analysis focuses on 11 in-depth interviews with truck drivers and a transport owner. A semi-structured interview guide was developed to elicit open-ended responses and enable probing. Interviews were conducted in Swahili, transcribed, and translated into English. Data analysis followed thematic analysis procedures that included initial reading of transcripts, development of a codebook and identification of themes through in-depth reading of transcripts. Drivers described structural risk factors for HIV including work conditions, the power imbalance between male drivers and their sexual partners and minimal perceived HIV risk with certain partners (e.g., regular partners and women selling sex). Multiple and inter-related social norms associated with truck stop environments influenced HIV risk, including peer influence and expectations, presence of sex workers, ability to purchase sex throughout their travel and alcohol consumption. These distinct social norms in truck stops and other rest points facilitated behavior that many participants said they would not engage in elsewhere. HIV prevention strategies with truck drivers should address individual, social and structural barriers to HIV prevention through partnerships with the health and transportation sectors, local government and local communities. HIV prevention services should be adapted to drivers' times and places of availability, for example, condom provision where/when drivers make decisions about or have sex. A focus on positive messaging and addressing specific challenges including the continual challenge of re-choosing and reinforcing decisions to engage in safer sexual behaviors is important.

Consistent Condom Use during Casual Sex among Long-Truck Drivers in Togo

BACKGROUND

In 2008, the proportion of truck drivers who were not systematically protected during sex was 63% with casual partners and 60% with sex workers. Despite the high level of knowledge on HIV/AIDS and the growing awareness of the existence of the risk of HIV infection, condom use always encounters resistance among truck drivers in Togo. We sought to document the factors associated with condom use during casual sex among trucks' drivers in Togo.

METHODS

This was an analytical cross-sectional study conducted in 2010 and targeted truckers at truck station on the two main roads of Togo, Lomé-Cinkassé and Kodjoviakopé-Sanvee Condji.

RESULTS

In this study, 1,782 trucks' drivers and their helpers were interviewed. All were men, and their mean age was 28.8 ± 8.8 years. Trucks' drivers were doing an average of 3 stops on their journeys and 1,229 (69%) of them had at least two years of experience in the work. Of the 1,782 trucks' drivers, only 620 (34.8%) had consistently used condoms during casual sex in the last three months. In multivariate analysis, predictors were: education level (primary schooling: OR = 1.54; p = 0.002; Secondary schooling and higher OR = 1.38; p = 0.036), good knowledge of ways of HIV transmission (OR = 1.53; p = 0.000), tested for HIV (OR = 1.67, p = 0.000), duration in the profession (2-5 years: OR = 1.43, p = 0.008; more than 5 years: OR = 1.38, p = 0.027), and HIV risk's perception (OR = 1.44, p = 0.000).

CONCLUSION

These results highlight factors associated with consistent condom use during casual sex by truck drivers in Togo. This is a key population group at high risk of HIV transmission toward which the national HIV/AIDS control program should strengthen the HIV prevention strategies.

Prevalence of HIV and Associated Risk Factors Among Long Distance Truck Drivers in Inchope, Mozambique, 2012

This is the first integrated biological and behavioral surveillance survey among long-distance truck drivers (LDTD) in Mozambique. Using modified time-location sampling in 2012 at a key transportation junction (Inchope), we enrolled 327 male LDTD. HIV prevalence was 15.4 % (95 % confidence interval : 11.4-19.4 %, n = 318 tested). Among HIV-positive LDTD, 83.7 % did not know their status. One-third of LDTD had never tested for HIV and three-quarters had not received free condoms, lubricants or HIV literature in the past 12 months. In that same period, 61.4 % of LDTD had at least four sexual partners and 27.1 % paid for sex. Among sexually-active LDTD, 76.5 % did not use a condom at last sex. HIV was associated (p < 0.05) with primary education or lower (AOR 2.1), residence in Mozambique (AOR 2.3) and never having tested for HIV (AOR 2.2). Our findings reveal that broader coverage of HIV prevention and comprehensive care services for LDTD are urgently needed.

Substance use and HIV infection awareness among HIV-infected female sex workers in Lilongwe, Malawi

BACKGROUND

HIV diagnosis, the first step in HIV care and treatment engagement, may be inhibited by substance use among female sex workers (FSW). We assessed the relationship between alcohol and cannabis use and lack of HIV infection awareness among HIV-infected FSW in Lilongwe, Malawi.

METHODS

From July to September, 2014, 200 FSW aged ≥18 years were enrolled using venue-based sampling to examine substance use, HIV testing history, and serostatus ascertained by HIV rapid test. We used Poisson regression with robust variance estimates to estimate the associations of alcohol and cannabis use and lack of HIV infection awareness.

RESULTS

Of the 138 HIV-infected FSW, 20% were unaware of their HIV infection, with 70% not testing within 6 months prior. According to the Alcohol Use Disorder Identification Tests (AUDIT), 55% of FSW unaware of their HIV infection reported hazardous, harmful, or dependent alcohol consumption. We observed a dose-response relationship between alcohol use and lack of HIV infection awareness, with alcohol dependency significantly associated with lack of HIV infection awareness (adjusted prevalence ratio: 3.0, 95% CI: 1.3, 6.8). Current cannabis use was uncommon (26%) among unaware HIV-infected FSW and weakly associated with lack of HIV infection awareness adjusted prevalence ratio: 1.1, 95% CI: 0.5, 2.5).

CONCLUSION

Increased levels of alcohol use is associated with lack of HIV infection awareness among HIV-infected FSW in Malawi. Frequent, consistent HIV testing integrated with alcohol reduction strategies could improve the health and infection awareness of substance-using FSW.

The HIV Care Continuum among Female Sex Workers: A Key Population in Lilongwe, Malawi

OBJECTIVE

The HIV care continuum among female sex workers (FSW), a key population, has not been well characterized, especially within the generalized epidemics of sub-Saharan Africa. This was the first study to characterize the HIV care continuum among FSW in Lilongwe, Malawi.

METHODS

From July through September 2014, we used venue-based sampling to enroll 200 adult FSW in Lilongwe, Malawi into a cross-sectional evaluation assessing HIV care continuum outcomes. Seropositive FSW, identified using HIV rapid testing, received rapid CD4 counts in addition to viral loads using dried blood spots. We calculated proportions of HIV-infected FSW who had history of care, were on ART, and had suppressed viral load and we used Poisson regression to estimate the associations of demographic characteristics and transmission risk behaviors with each outcome.

RESULTS

HIV seroprevalence was 69% (n = 138). Among all FSW the median age was 24 years (IQR: 22-28). Among the 20% who were newly diagnosed and reported previously testing negative, the median time since last HIV test was 11 months (interquartile range: 3-17). The majority (69%) of HIV-infected FSW had a history of HIV care, 52% reported current ART use, and 45% were virally suppressed. Of the FSW who reported current ART use, 86% were virally suppressed. Transmission risk behaviors were not associated with continuum outcomes.

CONCLUSIONS

FSW in Lilongwe were predominately young and have a high HIV prevalence. Only half of HIV-infected FSW reported current ART use, but the majority of those on ART were virally suppressed. To reduce ongoing transmission and improve health outcomes, increased HIV testing, care engagement, and ART coverage is urgently needed among FSW. Universal testing and treatment strategies for all FSW in Malawi must be strongly considered.

A systematic review of the clinical and social epidemiological research among sex workers in Uganda

BACKGROUND

In response to the high burden of disease among sex workers and their position as a population heavily affected by the HIV epidemic, there has been a growing body of literature investigating the prevalence and risk factors associated with HIV risk among sex workers. To contextualize and summarize the existing research evidence base, a systematic review was conducted to synthesize the epidemiological literature on sex workers in Uganda.

METHODS

Database selection and search strategy development followed the Cochrane Collaboration's standards for conducting systematic review searches. All studies that included sex workers as the primary research participants were included in the review. The search was then geographically restricted to the country of Uganda. Items were identified from 18 databases (grey and peer-review) on March 10-11, 2015.

RESULTS

A total of 484 articles were retrieved from the database search. After removal of duplicates, a total of 353 articles were screened for eligibility and 64 full-text articles were assessed. The final review included 24 studies with quantitative methodology conducted among sex workers in Uganda. The HIV prevalence among female sex workers ranged from 32.4-52.0 % and between 8.2-9.0 % had multiple HIV infections. Both multi-drug resistance to antiretroviral therapy (2.6 %) and antibiotics (83.1 %) were observed. Between 33.3-55.1 % reported inconsistent condom use in the past month. In the previous 6 months, over 80 % of sex workers experienced client-perpetrated violence and 18 % experienced intimate partner violence. Over 30 % had a history of extreme war-related trauma.

CONCLUSIONS

There was limited information on socio-structural factors that affect sex workers' commercial working environments in Uganda, including the role of policing and criminalization, as well as the prevalence and factors associated with violence. The majority of the existing evidence is based in Kampala, highlighting a need for information on sex work in other regions of Uganda. Additionally, there is limited information on features of the non-commercial components of sex workers' lives as well as the services needed to reduce risks outside of the sex industry.

Communicating about microbicides with women in mind: tailoring messages for specific audiences

Introduction

Current HIV prevention options are unrealistic for most women; however, HIV prevention research has made important strides, including on-going development of antiretroviral-based vaginal microbicide gels. Nevertheless, social-behavioural research suggests that women's ability to access and use new HIV prevention technologies will be strongly influenced by a range of socio-cultural, gender and structural factors which should be addressed by communications and marketing strategies, so that these products can be positioned in ways that women can use them.

Methods

Based on an extensive literature review and in-country policy consultation, consisting of approximately 43 stakeholders, we describe barriers and facilitators to HIV prevention, including potential microbicide use, for four priority audiences of Kenyan women (female sex workers [FSWs], women in stable and discordant relationships, and sexually active single young women). We then describe how messages that position microbicides might be tailored for each audience of women.

Results

We reviewed 103 peer-reviewed articles and reports. In Kenya, structural factors and gender inequality greatly influence HIV prevention for women. HIV risk perception and the ability to consistently use condoms and other prevention products often vary by partner type. Women in stable relationships find condom use challenging because they connote a lack of trust. However, women in other contexts are often able to negotiate condom use, though they may face challenges with consistent use. These women include FSWs who regularly use condoms with their casual clients, young women in the initial stages of a sexual relationship and discordant couples. Thus, we consider two approaches to framing messages aimed at increasing general awareness of microbicides – messages that focus strictly on HIV prevention and ones that focus on other benefits of microbicides such as increased pleasure, intimacy or sexual empowerment, in addition to HIV prevention.

Conclusions

If carefully tailored, microbicide communication materials may facilitate product use by women who do not currently use any HIV prevention method. Conversely, message tailoring for women with high-risk perception will help ensure that microbicides are used as additional protection, together with condoms.

Knowledge, attitudes & barriers to condom use among female sex workers and truck drivers in Uganda: a mixed-methods study

BACKGROUND

There is limited documentation on knowledge, attitudes and barriers to condom use among female sex workers (FSWs) and truck drivers (truckers).

OBJECTIVE

To explore knowledge, attitudes and barriers to condom use among FSWs and truckers operating along major transport corridors in Uganda.

METHODS

Structured questionnaires were administered to explore FSWs' and truckers' knowledge of and attitudes towards condom use among 259 FSWs and 261 truckers. Qualitative data were collected on barriers to condom use using focus group discussions. Quantitative data were analyzed using SPSS while qualitative data were audio-recorded, transcribed and thematically analyzed.

RESULTS

Condom knowledge was high with 97% of FSWs and 95% of truckers agreeing with the statement, "using condoms properly and consistently reduces risk of HIV infection". Attitudes towards condom use were generally favorable with 91% of FSWs and 82% of truckers agreeing with the statement, "condom use is the best method of HIV prevention". Qualitative findings show that poverty, refusal to use condoms by male partners, alcohol use before sex and beliefs that condoms 'kill the mood for sex' remain key barriers to consistent condom use.

CONCLUSIONS

Consistent condom use among FSWs and truckers is still hampered by economic and relationship factors.

The longitudinal association of venue stability with consistent condom use among female sex workers in two Mexico-USA border cities

We examined the relationship between venue stability and consistent condom use (CCU) among female sex workers who inject drugs (FSW-IDUs; n = 584) and were enrolled in a behavioural intervention in two Mexico-USA border cities. Using a generalized estimating equation approach stratified by client type and city, we found venue stability affected CCU. In Tijuana, operating primarily indoors was significantly associated with a four-fold increase in the odds of CCU among regular clients (odds ratio [OR]: 3.77, 95% confidence interval [CI]: 1.44, 9.89), and a seven-fold increase among casual clients (OR: 7.18, 95% CI: 2.32, 22.21), relative to FSW-IDUs spending equal time between indoor and outdoor sex work venues. In Ciudad Juarez, the trajectory of CCU increased over time and was highest among those operating primarily indoors. Results from this analysis highlight the importance of considering local mobility, including venue type and venue stability, as these characteristics jointly influence HIV risk behaviours.
