RESUMEN
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.

BACKGROUND: Alcohol use is pervasive among female sex workers (FSW) placing them at increased risk of violence and sexual risk behaviors. FSW often live and work where alcohol is highly normative. OBJECTIVE: To understand the socioecological influences on hazardous alcohol use among FSW in Malawi. METHODS: In 2014, 200 FSW identified through venue-based sampling in Lilongwe, Malawi, completed a quantitative behavioral survey, with a sub-sample participating in qualitative interviews. Multivariable log-binomial regression was used to identify associations between hazardous alcohol use (AUDIT score ≥ 7) and time in sex work, clients per week, unprotected sex, alcohol use with clients, and living environment. Qualitative interviews enhanced findings from quantitative data and identify emergent themes around socioecological influences on alcohol use. RESULTS: Over 50% reported hazardous alcohol use and lived in an alcohol-serving venue. Hazardous alcohol use was associated with sex work duration of ≥2 years (aPR: 1.30; 95%CI: 1.02,1.65) and alcohol use at last sex with a client (aPR: 1.29; 95%CI: 1.06,1.57). FSW perceived alcohol as a facilitator for sex work by reducing inhibitions and attracting clients, but acknowledged alcohol leads to violence and/or unprotected sex. Despite these risks and a motivation to reduce use, FSW feared that refusing to drink would be tantamount to turning away clients. CONCLUSIONS: Although FSW recognized alcohol-related risks, the norms and power dynamics of sex work perpetuated hazardous alcohol use. Multilevel interventions are needed to collectively change norms around drinking and sex work that will enable FSW to reduce alcohol consumption when engaging in their work.

Female sex workers (FSW) have a high prevalence of substance use and HIV, but the impact of substance use on HIV treatment engagement is not well established. We evaluated the association between alcohol and marijuana use and sub-optimal HIV treatment engagement outcomes among HIV-infected FSW in Lilongwe, Malawi. We enroled FSW using venue-based recruitment into a cross-sectional evaluation assessing substance use and HIV treatment engagement. Seropositive FSW, identified through HIV rapid testing, received rapid CD4 count and viral load testing. We used Poisson regression with robust variance estimates to ascertain associations of alcohol and marijuana use with sub-optimal HIV treatment outcomes: (1) lack of ART use among previously diagnosed, ART-eligible FSW and (2) viral nonsuppression among FSW on ART. Of previously diagnosed, ART-eligible FSW (n = 96), 29% were not using ART. Patterns of hazardous drinking were identified in 30%, harmful drinking in 10%, and alcohol dependence in 12%. ART-eligible FSW with harmful drinking or alcohol dependency were 1.9 (95% CI: 1.0, 3.8) times as likely to not use ART compared to FSW without harmful or dependent drinking. Among those on ART, 14% were virally nonsuppressed. The prevalence ratio for viral nonsuppression was 2.0 (95% CI: 0.6, 6.5) for harmful drinkers and alcohol-dependent FSW. Over 30% of ART-eligible FSW reported using marijuana. Marijuana-using FSW were 1.9 (95% CI: 0.8, 4.6) times as likely to not use ART compared to FSW who were not using marijuana. Given the high prevalence of alcohol use and its association with lack of ART use, ART uptake and alcohol reduction strategies should be tailored for alcohol-using FSW in Malawi.

Lack of social support and sex work stigma may hinder STI/HIV prevention for female sex workers (FSW). We explored the associations between sex work stigma and social support with sexual behaviors in Malawi. In 2017, 150 HIV-negative, venue-based FSW completed a behavioral survey containing sex work stigma items and social support. Linear binomial regression models were used to estimate prevalence differences of inconsistent condom use and substance use before sex by social support and stigma. A majority (93%) reported sex work-related internalized stigma. About 50% reported family or friend isolation. Social support was high (mean index: 86.53). Inconsistent condom use and substance use before sex had little to no association with stigma and social support. Malawian FSW largely internalize stigma and experience isolation from family and friends yet have high levels of social support. Large-scale evaluations should investigate the role of stigma and social support in STI/HIV prevention for FSW.

Female sex workers (FSW) are disproportionately at risk for HIV. Pre-exposure prophylaxis (PrEP) is an effective HIV prevention method, yet approaches for incorporating PrEP within prevention strategies used by FSW are lacking. Semistructured focus group discussions were conducted with 44 HIV-negative FSW in Lilongwe, Malawi to explore perceptions of PrEP: acceptability, integration within HIV prevention behaviors, and barriers to use. Acceptability of PrEP was high. Motivation to use PrEP was rooted in love for one's life, anticipated negative economic effects associated with HIV acquisition. PrEP was viewed as complementary to existing norms for engaging in healthy sexual behaviors. Many felt PrEP may provide extra protection from HIV, along with condoms and frequent STI testing. Unpredictable daily lives, stigma, and side effects were barriers that could affect PrEP use. Leveraging existing HIV prevention strategies and social norms surrounding HIV prevention behaviors may positively impact PrEP uptake among FSW in Malawi and sub-Saharan Africa.

Globally, female sex workers (FSW) experience a high prevalence of mental health disorders, but in sub-Saharan Africa these are rarely identified. If left untreated, mental health disorders may place FSW and their partners at risk for HIV/sexually transmitted infections (STIs). We assessed the prevalence and correlates of probable depression, post-traumatic stress disorder (PTSD), and suicidal ideation (SI) in a cohort of 200 FSW in Lilongwe, Malawi. FSW completed the Patient Health Questionnaire-9 and the PTSD Check List-Civilian Version. The prevalence of depression was 8%, as was the prevalence of PTSD. Nearly half (49%) of FSW were experiencing mild depression. FSW were more likely to have probable depression if they completed primary school or initiated sex work before 18 years. They were more likely to have probable PTSD if they had ≥ 20 clients per week or initiated sex work before 18 years. Interventions are needed to diagnose mental health disorders among FSW at great risk for HIV/STIs.
RESUMEN
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.

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.
