RESUMO

RESUMEN Objetivo. Describir los factores que determinan el uso del condón en trabajadores y trabajadoras sexuales inmigrantes venezolanos en Colombia. Métodos. Se realizó un estudio cualitativo con un enfoque hermenéutico interpretativo, en el cual se utilizó como técnica de investigación la entrevista semiestructurada, desarrolladas en el Área Metropolitana del Valle de Aburrá, Bogotá D.C. y el eje cafetero colombiano. Resultados. Se realizaron 55 entrevistas. Del total de personas entrevistadas, 60% eran hombres cisgénero, 31% mujeres cisgénero y 9% mujeres transgénero. La edad promedio de los participantes fue de 27 años. Sesenta y nueve por ciento se encuentra de manera irregular en Colombia. En cuanto a la afiliación al sistema de salud, solo 11% están afiliados. Se observó que el uso del condón en los trabajadores sexuales es inconsistente, ya que este depende de factores de tipo personal y social. Conclusiones. Los factores que influyen en el uso del condón en trabajadores y trabajadoras sexuales de origen venezolano en Colombia están determinados por diversos aspectos tanto personales como sociales. Los primeros se refieren a los conocimientos, las redes de apoyo y la percepción del riesgo, mientras que los sociales se asocian con el consumo de sustancias psicoactivas, el estigma y la discriminación, y los lugares para el ejercicio del trabajo sexual. Estos últimos son los que más influyen en el uso inconsistente del condón en hombres cisgénero y en mujeres transgénero.


ABSTRACT Objective. To describe the factors that determine condom use in Venezuelan immigrant sex workers in Colombia. Methods. A qualitative study was conducted with an interpretive hermeneutic approach, using semi-structured interviews developed in the Metropolitan Area of Aburrá Valley, Bogotá, and the Colombian coffee-growing region. Results. Fifty-five interviews were conducted. Of the total number of people interviewed, 60% were cisgender men, 31% were cisgender women, and 9% were transgender women. The average age of the participants was 27 years. Sixty-nine percent were irregular migrants in Colombia. Only 11% were affiliated with the health system. It was observed that condom use is inconsistent among sex workers, depending on personal and social factors. Conclusions. The factors that influence condom use in sex workers of Venezuelan origin in Colombia are determined by various factors, both personal and social. Personal factors relate to knowledge, support networks, and risk perception, while social factors are associated with substance use, stigma and discrimination, and the places where sex work is done. Social factors are the ones that most influence inconsistent condom use in cisgender men and transgender women.

RESUMO

BACKGROUND: Despite the established efficacy of PrEP to prevent HIV and the advantages of a user-controlled method, PrEP uptake and persistence by women in both trials and demonstration projects has been suboptimal. We utilized real-world data from an HIV service provider to describe persistence on oral PrEP among female sex workers (FSW) in eThekwini, South Africa. METHODS: We examined time from PrEP initiation to discontinuation among all FSW initiating PrEP at TB HIV Care in eThekwini between 2016-2020. We used a discrete time-to-event data setup and stacked cumulative incidence function plots, displaying the competing risks of 1) not returning for PrEP, 2) client discontinuation, and 3) provider discontinuation. We calculated hazard ratios using complementary log-log regression and sub-hazard ratios using competing risks regression. RESULTS: The number of initiations increased each year from 155 (9.3%, n = 155/1659) in 2016 to 1224 (27.5%, n = 1224/4446) in 2020. Persistence 1-month after initiation was 53% (95% CI: 51%-55%). Younger women were more likely to discontinue PrEP by not returning compared with those 25 years and older. Risk of discontinuation through non-return declined for those initiating in later years. Despite the COVID-19 pandemic, a greater number of initiations and sustained persistence were observed in 2020. CONCLUSIONS: Low levels of PrEP persistence were observed, consistent with data among underserved women elsewhere. Encouragingly, the proportion of women persisting increased over time, even as the number of women newly initiating PrEP and staff workload increased. Further research is needed to understand which implementation strategies the program may have enacted to facilitate these improvements and what further changes may be necessary.

RESUMO

We have previously reported that the female genital tract (FGT) of Beninese HIV highly-exposed seronegative (HESN) commercial sex workers (CSWs), presented elevated frequencies of a myeloid HLA-DR+CD14+CD11c+ population presenting "tolerogenic" monocyte derived dendritic cells (MoDC) features. In order to assess whether a differential profile of monocytes may be involved in the generation of these genital MoDCs, we have herein characterized the blood monocyte compartment of Beninese HESNs (HIV-uninfected ≥ 10 years CSWs) and relevant controls (HIV-uninfected 2.5-5 years CSWs herein termed "early HESNs"), HIV-infected CSWs, and low-risk HIV-uninfected women from the general population. Transcriptomic analyses by RNA-Seq of total sorted blood monocytes demonstrate that in comparison to the control groups, HESNs present increased expression levels of FCGR2C, FCAR, ITGAX, ITGAM, CR2, CD68, and CD163 genes, associated with effector functions. Moreover, we found increased expression levels of genes associated with protection/control against SHIV/HIV such as CCL3, CCL4, CCL5, BHLHE40, and TNFSF13, as well as with immune regulation such as IL-10, Ahr, CD83, and the orphan nuclear receptor (NR)4A1, NR4A2, and NR4A3. Through multicolor flow cytometry analyses, we noticed that the frequencies of intermediate and non-classical monocyte populations tended to be elevated in the blood of HESNs, and exhibited increased expression levels of effector CD16, CD11c, CD11b, as well as regulatory HLA-G, IL-10, and IFN-α markers when compared to HIV-uninfected women and/or HIV-infected CSWs. This profile is compatible with that previously reported in the FGT of HESNs, and likely confers an enormous advantage in their resistance to HIV infection.

RESUMO

BACKGROUND: Female sex workers (FSWs) are a marginalized group notoriously having limited healthcare access and poor-quality care. Inevitably, they are vulnerable to sexually transmitted infections including hepatitis B virus. However; Hepatitis B virus infection is one of the most serious infections and major public health problem considered to be at soaring risk for transmission and acquisition of the infection. Hence, this study was aimed to assess the prevalence and associated factors of HBV infections among FSWs in southern Ethiopia. METHODS: A cross-sectional study was conducted from November to February 2019 at Hawassa city in ISHDO confidential clinic among 383 FSWs. Respondent-driven consecutive sampling was used to select study participants using a standardized questionnaire. Blood sample was collected and viral surface antigen was detected using ELISA from separated serum. Data were entered to SPSS version 21.0. Descriptive and logistic regression analyses were used. RESULT: The overall prevalence of FSWs who were tested for HBV using ELISA was 35(9.2%) (95% CI: 6.3-12.1). Among 381 FSWs 249(65.4%) were stayed for 2-5 years in sexual work and 240(63%) of them were used condom consistently during sexual practice. In multivariate logistic regression analysis, FSWs who didn't use condom were six and two times more risk full to acquire HBV than those who used condom commonly (AOR = 6.38, CI 2.04-18.51) and condom breakage (AOR = 2.10, CI 1.95-4.65), during sexual practice respectively. Similarly, use of stimulants (AOR = 3.25, CI 1.59-18.63), previous history of STI (AOR = 2.15, CI 1.02-6.93), genital ulcer (AOR = 4.64, CI 1.31-11.35), number of sexual partners (AOR = 3.25, CI 1.59-7.47), sex during menses (AOR = 5.85, CI (1.29-21.44), sexual assault (AOR = 2.93, CI 1.23-9.01), sharp material sharing, (AOR = 4.98, CI 1.34-10.95) and history of abortion, (AOR = 2.46, CI 1.18, 12.19), were statistically associated with HBV infection. Factors such as age, residence, and alcohol consumption were not associated with HBV infection. CONCLUSION: The prevalence of HBV infection in this study was relatively high compared to the general population. Factors like sociodemographic, behavioral, and previous history-related information were associated with HBV infection shows the need for ongoing screening of high-risk population to inform planning for vaccination and preventive measures.

RESUMO

BACKGROUND: Hepatitis B and C are endemic in sub-Saharan Africa, with prevalence among the highest in the World. However, several challenges impede the progression towards the elimination of viral hepatitis by 2030 as suggested by the World Health Organization Global health sector strategy on viral hepatitis, including the lack of knowledge on the scale of this epidemic in the region. The aim of this study was to estimate the prevalence of hepatitis B and C among female sex workers (FSW) in Togo. METHODS: This ancillary study from a national cross-sectional bio-behavioral study was conducted in 2017 using a respondent-driven sampling (RDS) method, in eight towns of Togo among FSW. Socio-demographic, behavioral and sexual characteristics were assessed using a standardized questionnaire. Blood samples were collected for HIV, hepatitis B and C serological testing. Data were analyzed using descriptive analysis and a logistic regression model. RESULTS: Out of the 1,036 FSW recruited for this study, biological analyses for viral hepatitis were completed for 769 of them. The median age was 26 years [IQR: 22-33] and 49.8% (n = 383) had attained secondary school. The prevalence of hepatitis B was 9.9% [95% CI: (7.9-12.2)] and the prevalence of hepatitis C was 5.3% [95% CI: (3.9-7.2)]. Higher hepatitis B and C prevalence was associated with recruitment out of Lomé (aOR: 6.63; 95%CI: 3.51-13.40, p <0.001 and OR: 2.82; 95% CI: [1.37-5.99]; p<0.001, respectively) and, for hepatitis B, with never using condoms for vaginal intercourse (OR: 3.14; 95%CI: [1.02-8.71]; p<0.05). CONCLUSIONS: Results from this study reveals high prevalence of hepatitis B and C among FSW in Togo and an opportunity for advocacy toward the introduction of immunizations and treatment in this population.

RESUMO

INTRODUCTION: Key populations have disproportionately higher HIV prevalence rates than the general population. OBJECTIVE: To determine the level of virologic suppression and associated factors in female Commercial Sex Workers (CSW) who completed six months of ART and compare with the female general population (GP). METHODS: Clinical records of CSW and GPs who initiated ART between December 2014 to December 2016 from seven urban clinics were analyzed to determine virologic suppression (viral load < 1000 copies/ml) and associated factors. RESULTS: We identified 218 CSW and 182 female GPs. CSW had median age of 28 (IQR 25-31) vs 31 (IQR 26-37); median baseline CD4 446 (IQR 308-696) vs 352 (IQR 164-493) cells/microL; and optimal ART adherence levels at 70.6% vs 92.8% respectively, compared to GP. Virologic suppression in CSW and GPs was 85.7% and 89.6% respectively, P=0.28. Overall virologic suppression in CSW was 55% while Retention in care after 6 months of ART was 77.5%. Immediate ART initiation (<2weeks) and tuberculosis independently predicted virologic suppression in CSW with adjusted odds ratios 0.07 (95% C.I. 0.01-0.55, P=0.01) and 0.09 (95% C.I. 0.01-0.96, P=0.046) respectively. CONCLUSION: Virologic suppression in both groups is similar, however, intensified follow-up is needed to improve treatment outcomes.

RESUMO

Human T-lymphotropic virus 1 and 2 (HTLV-1/2) belong to the delta group of retroviruses which may cause a life-long infection in humans, HTLV-1 leading to adult T-cell leukemia/lymphoma and other diseases. Different transmission modes have been described, such as breastfeeding, and, as for other blood-borne pathogens, unsafe sexual activity, intravenous drug usage, and blood transfusion and transplantation. The present systematic review was conducted to identify all peer-reviewed studies concerning the work-related infection by HTLV-1/2. A literature search was conducted from January to May 2021, according to the PRISMA methodology, selecting 29 studies: seven related to health care workers (HCWs), five to non-HCWs, and 17 to sex workers (SWs). The findings showed no clear evidence as to the possibility of HTLV-1/2 occupational transmission in HCWs, according to the limited number and quality of the papers. Moreover, non-HCWs showed a higher prevalence in jobs consistent with a lower socioeconomic status or that could represent a familial cluster, and an increased risk of zoonotic transmission from STLV-1-infected non-human primates has been observed in African hunters. Finally, a general increase of HTLV-1 infection was observed in SWs, whereas only one paper described an increased prevalence for HTLV-2, supporting the urgent need for prevention and control measures, including screening, diagnosis, and treatment of HTLV-1/2, to be offered routinely as part of a comprehensive approach to decrease the impact of sexually transmitted diseases in SWs.

RESUMO

BACKGROUND: Key Population size estimation (PSE) is instrumental for HIV/STI preventive, treatment and care services planning, implementation and delivery. The objective was to estimate the overall population of female sex workers (FSW) in all the 16 regions of Ghana using different PSE methods. METHOD: Mapping of venues and complete enumeration of seaters was conducted at the formative stage prior to the bio-behavioral survey (BBS). Three PSE methods were used to derive the size estimates of FSW in the 16 regions. These include: Capture-recapture (CRC), service multiplier and three-source capture recapture (3SCRC) methods. The final choice of the estimation method used to estimate the roamer population was 3SCRC. This method was chosen because of its perfect record-linkage-hierarchic combination of three names that minimizes overmatching as well as the addition of an interaction term in the model which corrects for the dependencies in CRC. RESULTS: The total population size estimate of the female sex workers in the country obtained for roamers using capture re-capture was 41,746 (95% CI: 41,488-41,932). Using the service multiplier, the total population for both the roamers and seaters was 41,153 (95% CI: 37,242-45,984). The 3-source capture re-capture yielded 55,686 roamers FSW (95% CI: 47,686-63,686). The seater population was 4,363 FSW based on census/complete enumeration. The total population size estimate of FSW (seaters and roamers) in Ghana was 60,049 when 3SCRC and census were added. This represents about 0.76% of all estimated adult females aged 15-49yrs in Ghana. CONCLUSION: We report population size estimates (PSE) for FSW in Ghana. These estimates are the results of 3SCRC. These findings provide a valid and reliable source of information that should be referenced by government officials and policymakers to plan, implement and provide HIV/STI preventive, treatment, and care services for FSW in Ghana.

RESUMO

FREM1 (Fras-related extracellular matrix 1) and its splice variant TILRR (Toll-like interleukin-1 receptor regulator) have been identified as integral components of innate immune systems. The potential involvement of FREM1 in HIV-1 (human immunodeficiency virus 1) acquisition was suggested by a genome-wide SNP (single nucleotide polymorphism) analysis of HIV-1 resistant and susceptible sex workers enrolled in the Pumwani sex worker cohort (PSWC) in Nairobi, Kenya. The studies showed that the minor allele of a FREM1 SNP rs1552896 is highly enriched in the HIV-1 resistant female sex workers. Subsequent studies showed that FREM1 mRNA is highly expressed in tissues relevant to mucosal HIV-1 infection, including cervical epithelial tissues, and TILRR is a major modulator of many genes in the NF-κB signal transduction pathway. In this article, we review the role of FREM1 and TILRR in modulating inflammatory responses and inflammation, and how their influence on inflammatory responses of cervicovaginal tissue could enhance the risk of vaginal HIV-1 acquisition.

RESUMO

The purpose of the present research is to analyze temporal tend, victim's and perpetrator's specific features and the role of risk factors of femicides assessed at the Institute of Legal Medicine of Milan (in the North of Italy) from 2006 to 2020. The classical definition of femicide (the killing of a woman because of her gender) was used, in order to exclude murders of a woman because of economic issues, neighborhood quarrels, vengeance for previous discussions and other motives. Data were obtained from autopsies findings, local papers and victim relatives' interviews. The analysis of 86 femicides occurred in the judicial district of the Cities of Milan and Monza from 2006 to 2020 were performed. The results show the temporal distribution of the phenomenon, the methods of murders, the mean age of the victims, victims and perpetrators' relationship and nationality, risk factors. Although a reduction in the total number of femicides was observed, the percentage of femicides when compared to the total number of homicides was the same. Also, an increasing mean age of the victims over the period emerged. Moreover, the analysis of nationality of the victims and the perpetrators did not reflect foreign citizens distribution in Italy.

RESUMO

OBJECTIVE: To characterise epidemiology of herpes simplex virus type 2 (HSV-2) in Latin America and the Caribbean. METHODS: HSV-2 reports were systematically reviewed and synthesised, and findings were reported following Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Meta-analyses and metaregressions were conducted. FINDING: 102 relevant reports were identified including 13 overall incidence measures, 163 overall (and 402 stratified) seroprevalence measures, and 7 and 10 proportions of virus detection in genital ulcer disease and in genital herpes, respectively. Pooled mean seroprevalence was 20.6% (95% CI 18.7% to 22.5%) in general populations, 33.3% (95% CI 26.0% to 41.0%) in intermediate-risk populations, 74.8% (95% CI 70.6% to 78.8%) in female sex workers, and 54.6% (95% CI 47.4% to 61.7%) in male sex workers, men who have sex with men and transgender people. In general populations, seroprevalence increased from 9.6% (95% CI 7.1% to 12.4%) in those aged <20 years to 17.9% (95% CI 13.6% to 22.5%) in those aged 20-30, 27.6% (95% CI 21.4% to 34.2%) in those aged 30-40 and 38.4% (95% CI 32.8% to 44.2%) in those aged >40. Compared with women, men had lower seroprevalence with an adjusted risk ratio (ARR) of 0.68 (95% CI 0.60 to 0.76). Seroprevalence declined by 2% per year over the last three decades (ARR of 0.98, 95% CI 0.97 to 0.99). Pooled mean proportions of HSV-2 detection in GUD and genital herpes were 41.4% (95% CI 18.9% to 67.0%) and 91.1% (95% CI 82.7% to 97.2%), respectively. CONCLUSIONS: One in five adults is HSV-2 infected, a higher level than other world regions, but seroprevalence is declining. Despite this decline, HSV-2 persists as the aetiological cause of nearly half of GUD cases and almost all of genital herpes cases.

RESUMO

Phylogenetic inference is useful in characterising HIV transmission networks and assessing where prevention is likely to have the greatest impact. However, estimating parameters that influence the network structure is still scarce, but important in evaluating determinants of HIV spread. We analyzed 2017 HIV pol sequences (728 Lake Victoria fisherfolk communities (FFCs), 592 female sex workers (FSWs) and 697 general population (GP)) to identify transmission networks on Maximum Likelihood (ML) phylogenetic trees and refined them using time-resolved phylogenies. Network generative models were fitted to the observed degree distributions and network parameters, and corrected Akaike Information Criteria and Bayesian Information Criteria values were estimated. 347 (17.2%) HIV sequences were linked on ML trees (maximum genetic distance ≤4.5%, ≥95% bootstrap support) and, of these, 303 (86.7%) that consisted of pure A1 (n = 168) and D (n = 135) subtypes were analyzed in BEAST v1.8.4. The majority of networks (at least 40%) were found at a time depth of ≤5 years. The waring and yule models fitted best networks of FFCs and FSWs respectively while the negative binomial model fitted best networks in the GP. The network structure in the HIV-hyperendemic FFCs is likely to be scale-free and shaped by preferential attachment, in contrast to the GP. The findings support the targeting of interventions for FFCs in a timely manner for effective epidemic control. Interventions ought to be tailored according to the dynamics of the HIV epidemic in the target population and understanding the network structure is critical in ensuring the success of HIV prevention programs.

RESUMO

Sexually transmitted infections (STIs) represent a worldwide public health problem and, although many of them are curable, they continue to be neglected, especially in areas with a low human development index, such as in the northern region of Brazil. This review describes the results of 30 years of studies at the Virus Laboratory at the Federal University of Pará, including the prevalence and molecular epidemiology of HIV-1, HTLV-1/2, HPV, HBV, Treponema pallidum and Chlamydia trachomatis among urban and non-urban populations, and also in vulnerable groups in the Brazilian Amazon. Control strategies and challenges in preventing STIs are discussed considering this immense geographic region, where essential health services are unable to reach the entire population, especially the most vulnerable, such as female sex workers, people who use illicit drugs, remnants of quilombolos and indigenous communities.

RESUMO

BACKGROUND: We constructed self-reported pre-exposure prophylaxis (PrEP) cascades and explored factors associated with and barriers to PrEP use to inform efforts to support PrEP use among young women who sell sex. METHODS: Using self-reported data from HIV-negative young women who sell sex enrolled into a cohort study using respondent-driven sampling in Zimbabwe, we constructed PrEP cascades assessing knowledge of, ever offered, ever used, and current PrEP use in 2017 and 2019. We used logistic regression to examine factors associated with PrEP use by 2019. Through qualitative interviews with 43 women enrolled in the cohort, we investigated barriers to PrEP use. RESULTS: At enrollment, 50% of women had heard of PrEP, 12% had ever been offered PrEP, and 7% ever used PrEP. Over time, all cascade domains: 96% of women had heard of and 55% reported an active offer of PrEP. Among women retained in the study in 2019 (56%; n = 538), 34% ever took PrEP by 2019. PrEP use was associated with, at enrollment, reporting more clients in the past month (10+: 45% vs 1-3: 27% adjOR = 1.71 95% CI: 1.06 to 2.76), duration of selling sex (24% <2 years vs 38% 2-3 years; adjOR = 0.51 95% CI: 0.32 to 0.83), and having visited a female sex worker program in the past 12 months (55% vs 27%; adjOR = 2.92 95% CI: 1.91 to 4.46). Qualitative interviews revealed fear of disclosing sex work, HIV-related/ART-related stigma, and (opportunity) costs of accessing PrEP as barriers to use. CONCLUSION: PrEP use was associated with factors known to increase HIV risk. Fear of stigma, disclosure, and supply-side barriers need to be addressed to increase women's ability to use PrEP.

RESUMO

BACKGROUND: Young adult sex workers may benefit from sexual and reproductive health care services; however, little research has examined their access experiences. This study aimed to assess barriers to and facilitators of access to sexual and reproductive health care among young adult sex workers, and identify practices suggested by participants to improve services. METHODS: This was a community-based mixed-methods study of adults aged 18-29 years who were currently or had previously been engaged in sex work, conducted in Toronto in 2017-2018. The study was guided by a Youth Advisory Committee of 4 youth with lived experience of sex work. Participants completed an online survey, or participated in a focus group or a one-on-one interview; all 3 modalities included parallel questions about barriers to and facilitators of access to sexual and reproductive health care. We summarized quantitative data using descriptive statistics and identified qualitative themes using thematic analysis, followed by triangulation of the 2 strands. RESULTS: There were 54 survey respondents (response rate 48%) and 17 participants in the qualitative phase (14 in focus groups and 3 in interviews), for a total sample size of 71. Survey respondents reported suboptimal access to sexual and reproductive health care, with 8 (15%) reporting no regular source of care, and only 6 (11%) reporting that they disclose their sex work experience to providers. Actual or expected stigma regarding sex work on the part of providers was the dominant barrier to care, whereas nonjudgmental providers, particularly those who themselves have sex work experience, was a key facilitator. Participants suggested 7 practices to improve access to sexual and reproductive health care. INTERPRETATION: Young adult sex workers face many barriers to accessing sexual and reproductive health care. Including people with sex work experience in the development of solutions will maximize the capacity to address the needs of this underserved population.

RESUMO

BACKGROUND: There are limited published data on factors related to risky sexual practices (RSP) affecting sexually transmitted infections (STIs) among female sex workers (FSWs) in Ecuador. METHODS: Cross-sectional study of FSWs presenting for a consultation in a primary health care centre during 2017. A questionnaire was administered to collect information on RSP and potential risk factors including age, membership of an FSW association, self-report of previous STI diagnosis, previous treatment for suspected STI and temporary migration for sex work. Associations between RSP and potential risk factors were estimated by logistic regression. The proportion of STI was estimated from vaginal swabs by real-time PCR for four sexually transmitted pathogens (Neisseria gonorrhoeae, Trichomonas vaginalis, Chlamydia trachomatis, and Mycoplasma genitalium). RESULTS: Of 249 FSWs recruited, 22.5% had reported RSPs at least once during sex work. Among FSWs reporting unprotected vaginal sex in the previous three months, 25.5% had at least one other RSP type. 17.6% (95%CI 13.3-22.8) had at least one active STI. Prevalence of co-infections was 2.4% (95%CI 1.1-5.2). In multivariable analysis, RSP was associated with age (adjusted OR 1.06; 95%CI 1.02-1.10), membership of an FSWs association (aOR 3.51; 95%CI 1.60-7.72) and self-reported previous STI (aOR 3.43; 95%CI 1.28-9.17). CONCLUSIONS: Among a population of female sex workers with high proportion of STIs, increasing age and belonging to an FSWs association was associated with a higher likelihood of engaging in RSP with clients. Engaging with FSWs organisations may reduce the burden of STI among sex workers.

RESUMO

INTRODUCTION: Intimate Partner Violence (IPV) is linked to low engagement with HIV management services and adverse clinical outcomes, including poor ART adherence. In sub-Saharan Africa, studies on pregnant/postpartum women and transactional sex workers have produced divergent evidence regarding IPV's association with poor ART adherence. We investigate this association among a broad group of women. METHODS: We sampled 408 HIV-positive women receiving free ART from different types of HIV clinics at government health facilities, assessing for IPV exposure by a current partner, ART adherence rate, and other factors that affect ART adherence (e.g. education, disclosure). ART adherence rates were measured using the Visual Analogue Scale (VAS); responses were dichotomised at a ≥95% cut-off. Multiple logistic regression models assessed the association between the independent variables and ART adherence. RESULTS: The participants' mean age was 38.6 (range: 18-69 years). The majority had ever attended school (94%, n = 382), were in monogamous marriages (70%, n = 282), and had disclosed status to partners (94%, n = 380). Overall, 60% (n = 242) reported optimal ART adherence (≥ 95%) in the previous 30 days. The prevalence of IPV by the current partner was 76% (CI95 = 72-80%). Experiencing physical IPV (AOR 0.57, CI95: 0.34-0.94, p = .028), sexual IPV (AOR 0.50, CI95: 0.31-0.82, p = .005), or controlling behaviour (AOR 0.56, CI95: 0.34-0.94, p = .027) reduced the odds of achieving optimal adherence, while a higher education level and having an HIV-positive partner increased the odds. CONCLUSION: IPV is common and is associated with suboptimal ART adherence rates among a broad group of HIV-positive women. ART programs could consider incorporating basic IPV interventions into regular clinic services to identify, monitor and support exposed women, as they might be at risk of poor ART adherence. Still, there is need for more research on how IPV affects ART adherence.

RESUMO

The provision of comprehensive prevention services is vital for reducing the high burden of HIV amongst Ukrainian female sex workers (FSWs). To identify barriers and facilitators that influence access to HIV prevention amongst this population between 2009 and 2017, we developed a literature-informed conceptual framework and conducted a document analysis to identify the components of the Ukrainian prevention package (PP). Using the Integrated Bio Behavioural Surveillance Surveys, we then conducted descriptive analyses to explore PP coverage from 2009 to 2017 and the influence of factors, identified by our conceptual framework. After increasing over four years, a drop in PP coverage was observed from 2013 onwards. Being a client of a non-governmental organisation, street and highway solicitation, non-condom use, and knowledge of HIV may influence access to HIV prevention in the Ukrainian context. Future interventions should consider barriers and facilitators to HIV prevention and the multiple structural levels on which they operate.

RESUMO

Past studies that have designed interventions to reduce the prevalence of sexually transmitted infections (STIs) have typically provided onsite treatment to sex workers who tested positive, which were expensive and difficult to implement. The purpose of this study was to examine the effect of an intervention which tested for STIs and provided information on the closest treatment facility on reducing the prevalence of STIs among female brothel-based sex workers (BSWs) in Bangladesh. The study adopted a pre-post interventional design as well as a randomized controlled study design. A baseline sample and follow-up urine sample were collected to evaluate the prevalence of STIs among participants in the treatment, but not control group. A baseline survey and interviews were also conducted for both the groups. The study found a nonsignificant reduction from baseline to follow-up in STI prevalence among intervention participants (adjusted odds ratio [aOR]: 0.74; 95% CI: 0.38, 1.45). However, the participants in the intervention group were significantly more likely to have a repeat client (aOR: 1.60; 95% CI: 1.12, 2.29) and nonsignificantly less likely to engage with a client suspected of having an STI (aOR: 0.62; 95% CI: 0.39, 1.00) than participants in the control group. The intervention testing of STIs and providing information to the positive cases about nearest treatment facilities were not effective in reducing the prevalence of STIs among BSWs. Further study of the clinical and behavioral impacts of such efforts to reduce STIs among BSWs is warranted.

RESUMO

OBJECTIVES: This study in female sex workers (FSWs) aimed to: (1) estimate type-specific incidence and persistence of human papillomavirus (HPV) infection in Cotonou (Benin) and Bamako (Mali); and (2) identify the factors associated with type-specific incidence and persistence of high-risk HPV (HR-HPV) infection. METHODS: A 1-year prospective cohort study on cervical cancer screening, and HPV and human immunodeficiency virus (HIV) infections was conducted among FSWs in Cotonou and Bamako from 2017 to 2019. Poisson regression models assessed factors associated with the incidence of HR-HPV infection, while log-binomial regression was performed to identify factors associated with the persistence of HR-HPV infection. Adjusted relative risks (ARR) and 95% confidence intervals (95% CI) were estimated. RESULTS: The incidence of HR-HPV infection was 46.98 per 1000 women-months (predominant types HPV16, HPV35 and HPV59). Factors associated with the incidence of HR-HPV infection were age <20 years (ARR 15.10; 95% CI 3.29-69.19), age at sexual debut <18 years (ARR 6.92; 95% CI 1.97-24.27) and sex work duration ≤1 year (ARR 7.40; 95% CI 1.84-29.69). The persistence of HR-HPV infection at 12 months was 38.7% (most persistent types HPV59, HPV52 and HPV51). Persistence of HR-HPV infection was higher in women with chlamydia (P = 0.031), HIV infection (P < 0.001) and multiple-type HPV infections (P < 0.001). CONCLUSION: FSWs in West Africa are at high risk of incident and persistent HR-HPV infection, suggesting an urgent need for cervical cancer screening in this population.
