Abstract
OBJECTIVES This study examined whether HIV status and antiretroviral therapy (ART) exposure were associated with self-reported hypertension in Zimbabwe. DESIGN Study data were taken from a cross-sectional, general population survey, which included HIV testing (July 2018-December 2019). SETTING The data were collected in Manicaland Province, Zimbabwe. PARTICIPANTS 9780 people aged 15 years and above were included. OUTCOME MEASURE Self-reported hypertension was the outcome measure. This was defined as reporting a previous diagnosis of hypertension by a doctor or nurse. After weighting of survey responses by age and sex using household census data, χ2 tests and logistic regression were used to explore whether HIV status and ART exposure were associated with self-reported hypertension. RESULTS The weighted prevalence of self-reported hypertension was 13.6% (95% CI 12.9% to 14.2%) and the weighted prevalence of HIV was 11.1% (10.4% to 11.7%). In univariable analyses, there was no evidence of a difference in the weighted prevalence of self-reported hypertension between people living with HIV (PLHIV) and HIV-negative people (14.1%, 11.9% to 16.3% vs 13.3%, 12.6% to 14.0%; p=0.503) or between ART-exposed and ART-naive PLHIV (14.8%, 12.0% to 17.7% vs 12.8%, 9.1% to 16.4%,p=0.388). Adjusting for socio-demographic variables in logistic regression did not alter this finding (ORs:HIV status:0.88, 0.70 to 1.10, p=0.261; ART exposure:0.83, 0.53 to 1.30, p=0.411). CONCLUSIONS Approximately one in seven PLHIV self-reported having hypertension, highlighting an important burden of disease. However, no associations were found between HIV status or ART exposure and self-reported hypertension, suggesting that it will be valuable to focus on managing other risk factors for hypertension in this population. These findings should be fully accounted for as Zimbabwe reorients its health system towards non-communicable disease control and management.

Abstract
Use of HIV testing services among FSW in sub-Saharan Africa (SSA) is below the desired UNAIDS target of 90%. We estimated the prevalence and factors associated with HIV testing among FSW in Dar es Salaam, Tanzania. A respondent-driven sampling method was used to recruit FSW aged 18. Modified Poisson regression models were used to determine factors associated with recent HIV testing. Of 958 surveyed FSW (median age 26 years), 85.4% (95% CI: 82.3, 88.1) reported to have ever been tested for HIV and 65.3% (95% CI: 61.2, 69.3) tested in the past 12 months. Condom use on the last day worked (prevalence ratio (PR) = 1.17; 95% CI: 0.99, 1.38), no or low self-perceived risk of HIV acquisition (PR = 1.16; 95% CI: 1.02, 1.32), having never felt stigmatized as a sex worker (PR = 1.18; 95% CI: 1.04, 1.33), and having been in contact with a peer educator (PR = 1.33; 95% CI: 1.18, 1.49) during the past year preceding the survey were associated with recent HIV testing. Interventions aiming to mitigate stigma due to sex work, improve health education to address risk perception as a barrier to HIV testing, and scaling up peer educator's engagement should be given priority.

Abstract
BACKGROUND Benin has a long-standing history of HIV prevention programs aimed at female sex workers (FSWs). We used data from a national survey among FSWs (2017) to assess the prevention and care cascades in this population. METHODS Female sex workers were recruited through cluster sampling of sex work sites. A questionnaire was administered, and HIV tested. HIV-positive participants were asked to provide dried blood spots and were tested for antiretroviral and viral load. We assessed 2 prevention cascades (HIV testing and safer sex) and the treatment cascade, using a combination of self-reported and biological variables. RESULTS Mean age of the 1086 FSWs was 30 years. Half of them were Beninese, and two-thirds had a primary school education level or less. Almost all FSWs had ever heard of HIV/AIDS. More than half (79.1%) had ever been tested, and 84.1% of the latter had been tested in the last year. In the previous 6 months, 90.1% were exposed to prevention messages. Women exposed to any HIV prevention message reported a higher level of consistent condom use in the last month (69.0%) than those who were not (48.5%, P < 0.0001). HIV prevalence was 7.7%. Among HIV-positive women, 60.6% knew their status; among those, 90.5% were on antiretroviral and 81.8% of them had a suppressed viral load. CONCLUSIONS Despite long-standing HIV prevention programs for FSWs, the prevention indicators were often low. Linkage to care was good, viral suppression was suboptimal, but knowledge of HIV-positive status was low. Exposing women to prevention messages is necessary, as to increase HIV testing.

Abstract
We sought to find a method that improves HIV estimates obtained through time-location sampling (TLS) used to recruit most-at-risk populations (MARPs). The calibration on residuals (CARES) method attributes weights to TLS sampled individuals depending on the percentile to which their logistic regression residues belong. Using a real country database, provided by EMIS-2010, with 9591 men who have sex with men (MSM) and an HIV prevalence of 12.1%, we simulated three populations (termed "pseudo-populations") with different levels of HIV. From each pseudo-population, 1000 TLS samples were drawn, and the HIV prevalence estimated by the TLS method and by the CARES method were recorded and compared with the HIV prevalence of the 9591 men. Results showed that the CARES method improves estimates given by the TLS method by getting closer to the real HIV prevalence.

Abstract
Declines in HIV incidence have been slower than expected during the roll-out of antiretroviral treatment (ART) services in sub-Saharan African populations suffering generalized epidemics. Using data from a population-based, open cohort HIV sero-survey (2004-13), we found evidence for initial reductions in sexual activity and multiple sexual partnerships, followed by increases during the period of ART scale-up in areas of high HIV prevalence in Manicaland, east Zimbabwe. Recent population-level increases in condom use were also recorded, but largely reflected high use by the rapidly growing proportion of HIV-infected individuals on treatment. Sexual risk behaviour increased in susceptible uninfected individuals and in untreated (and therefore more infectious) HIV-infected men, which may have slowed the decline in HIV incidence in this area. Intensified primary HIV prevention programmes, together with strengthened risk screening, referral, and support services following HIV testing, could help to maximize the impact of 'test-and-treat' programmes in reducing new infections.

Abstract
BACKGROUND The psychological health of female sex workers (FSWs) has emerged as a major public health concern in many low- and middle-income countries (LMICs). Key risk factors include poverty, low education, violence, alcohol and drug use, human immunodeficiency virus (HIV), and stigma and discrimination. This systematic review and meta-analysis aimed to quantify the prevalence of mental health problems among FSWs in LMICs, and to examine associations with common risk factors. METHOD AND FINDINGS The review protocol was registered with PROSPERO, number CRD42016049179. We searched 6 electronic databases for peer-reviewed, quantitative studies from inception to 26 April 2020. Study quality was assessed with the Centre for Evidence-Based Management (CEBM) Critical Appraisal Tool. Pooled prevalence estimates were calculated for depression, anxiety, post-traumatic stress disorder (PTSD), and suicidal behaviour. Meta-analyses examined associations between these disorders and violence, alcohol/drug use, condom use, and HIV/sexually transmitted infection (STI). A total of 1,046 studies were identified, and 68 papers reporting on 56 unique studies were eligible for inclusion. These were geographically diverse (26 countries), representing all LMIC regions, and included 24,940 participants. All studies were cross-sectional and used a range of measurement tools; none reported a mental health intervention. Of the 56 studies, 14 scored as strong quality, 34 scored as moderate, and 8 scored as weak. The average age of participants was 28.9 years (age range: 11-64 years), with just under half (46%) having up to primary education or less. The pooled prevalence rates for mental disorders among FSWs in LMICs were as follows: depression 41.8% (95% CI 35.8%-48.0%), anxiety 21.0% (95% CI: 4.8%-58.4%), PTSD 19.7% (95% CI 3.2%-64.6%), psychological distress 40.8% (95% CI 20.7%-64.4%), recent suicide ideation 22.8% (95% CI 13.2%-36.5%), and recent suicide attempt 6.3% (95% CI 3.4%-11.4%). Meta-analyses found significant associations between violence experience and depression, violence experience and recent suicidal behaviour, alcohol use and recent suicidal behaviour, illicit drug use and depression, depression and inconsistent condom use with clients, and depression and HIV infection. Key study limitations include a paucity of longitudinal studies (necessary to assess causality), non-random sampling of participants by many studies, and the use of different measurement tools and cut-off scores to measure mental health problems and other common risk factors. CONCLUSIONS In this study, we found that mental health problems are highly prevalent among FSWs in LMICs and are strongly associated with common risk factors. Study findings support the concept of overlapping vulnerabilities and highlight the urgent need for interventions designed to improve the mental health and well-being of FSWs.

Abstract
Supplemental Digital Content is Available in the Text. Background: Intimate partner violence (IPV) is common among female sex workers (FSW) globally. Here, we prospectively assessed the relationship between IPV and engagement in HIV care in a cohort of FSW who had been newly diagnosed with HIV. Methods: Data arose from the Zambian Peer Educators for HIV Self-Testing study, a randomized controlled trial of HIV self-test distribution among FSW in 3 transit towns in Zambia. Participants were self-reported to be HIV-uninfected or unaware of their status at baseline. IPV in the previous 12 months was assessed at baseline. At 4 months, participants were asked the results of their last HIV test and those who reported testing positive were asked whether they had engaged in HIV-related care and started antiretroviral therapy (ART). Results: Of 964 participants, 234 (24.3%) reported that they were living with HIV at 4 months. Of these 234 participants, 142 (60.7%) reported a history of IPV (past 12 months) at baseline and at 4 months, 152 (65.0%) reported that they were in HIV-related care, and 132 (56.7%) reported that they had initiated ART. Participants who reported IPV had significantly reduced odds of engagement in care (adjusted odds ratio = 0.48, 95% confidence interval: 0.26 to 0.91) and ART initiation (adjusted odds ratio = 0.40, 95% confidence interval: 0.22 to 0.72). Conclusions: FSW living with HIV in Zambia reported very high rates of IPV. Structural and individual interventions for violence prevention are urgently needed to better protect this population. Given the strong negative relationship between IPV and engagement in HIV-related care, such interventions could also substantially improve HIV-related health outcomes.
