RESUMO

Men who engage in transactional sex with men (MTSM) are a high-risk population for HIV and other sexually transmitted infections. Epidemiological data have so far included them in the broad category of men who have sex with men (MSM), while research on transactional sex typically focused on female sex workers. The internet has substantially changed sex work practices and earlier findings concerning the sexual health needs of MTSM may no longer be applicable. We analyzed quantitative data from MSM based in the UK (n = 11629) taking part in the European MSM Internet Survey (EMIS-2017). Compared to non-MTSM, MTSM (n = 230; 2%) were younger, more likely to self-identify as an ethnic minority, be single, have lower education levels, struggle financially, and-controlling for age-more likely to be living with diagnosed HIV. Commonly unmet needs among all MSM were a lack of confidence in accessing HIV post-exposure prophylaxis, uncertainty about HIV status, and ignorance of where to access hepatitis vaccinations. Compared with other MSM, MTSM were notably less satisfied with the safety of their sexual practices, less confident in their ability to maintain sexual boundaries, and more likely to engage in risk because of absent precautionary resources. Given their greater opportunity for sexual risk, as well as fewer resources for negotiating safety, our findings suggest that services should prioritize MTSM in HIV prevention and sexual health promotion, including assertiveness and social skills training, in addition to knowledge-based education.

RESUMO

In Surat city of Gujarat, India, female sex workers (FSW)-based targeted interventions (TI) and community-based organizations (CBO) have been functioning since 1998. To document the impact of the COVID-19 lockdown (March-May 2020) on FSWs and STI/RTI/HIV preventive measures provided through TI/CBOs in Surat city, sequential, explanatory mixed-methods design was used. We conducted a desk review of quarterly programmatic data (2018-2020) of four TIs and CBOs and interviewed of 221 FSWs to study pre- and post-lockdown socioeconomic conditions, engagement in sex work, health services during COVID-19 lockdown and coping strategies, followed by five focus group discussions of FSWs and TI/CBO project staff. Study identified four major themes: reasons for working as a FSW during COVID-19 lockdown, entry to sex work during or as a consequence of lockdown, exploitation of FSWs during lockdown, and challenges of TI and CBOs in service provision in pandemic situation. Number of new registrations and STI/RTI detection increased immediately after lockdown. TI/CBO and other NGOs working for women welfare must build financial independence by training them in microeconomics, savings, and entrepreneurship. TI/CBO staff must also include experts in finance or business, trained in emergency response. The presence of strong TI/CBO network facilitated prompt delivery of essential commodities and financial aid to FSWs. However, laboratory and screening services were hampered, which warrants need of introducing self-test kits. In backdrop of decrease in condom distribution, continuation of sex work during lockdown and disruption of routine HIV/STI/RTI screening facilities, our study also recommends intensified HIV/STI/RTI screening among FSWs.

RESUMO

BACKGROUND: Structural, interpersonal and individual level factors can present barriers for HIV prevention behaviour among people at high risk of HIV acquisition, including women who sell sex. In this paper we document the contexts in which women selling sex in Kampala meet and provide services to their clients. METHODS: We collected qualitative data using semi-structured interviews. Women were eligible to participate if they were 18 years or older, self-identified as sex workers or offered sex for money and spoke Luganda or English. Ten women who met clients in venues and outdoor locations were selected randomly from a clinic for women at high risk of HIV acquisition. Ten other women who met clients online were recruited using snowball sampling. Interviews included demographic data, and themes included reasons for joining and leaving sex work, work locations, nature of relationships with clients and peers, interaction with authorities, regulations on sex work, and reported stigma. We conducted interviews over three months. Data were analysed thematically using a framework analysis approach. The coding framework was based on structural factors identified from literature, but also modified inductively with themes arising from the interviews. RESULTS: Women met clients in physical and virtual spaces. Physical spaces included venues and outdoor locations, and virtual spaces were online platforms like social media applications and websites. Of the 20 women included, 12 used online platforms to meet clients. Generally, women from the clinic sample were less educated and predominantly unmarried, while those from the snowball sample had more education, had professional jobs, or were university students. Women from both samples reported experiences of stigma, violence from clients and authorities, and challenges accessing health care services due to the illegality of sex work. Even though all participants worked in settings where sex work was illegal and consequently endured harsh treatment, those from the snowball sample faced additional threats of cybersecurity attacks, extortion from clients, and high levels of violence from clients. CONCLUSIONS: To reduce risk of HIV acquisition among women who sell sex, researchers and implementers should consider these differences in contexts, challenges, and risks to design innovative interventions and programs that reach and include all women.

RESUMO

BACKGROUND: During the early period of the COVID-19 pandemic, public health orders disrupted income generation in numerous sectors and many governments provided emergency financial support. Access to government support and changes in engagement in sex work during the early period of the pandemic among people who use drugs (PWUD) are not well described. In the present study, we investigate the prevalence and correlates of engaging in sex work during the COVID-19 pandemic, among PWUD in Vancouver, Canada. METHODS: Data derived from three harmonized cohorts of PWUD. Using multivariable logistic regression, we characterized factors associated with engaging in sex work in the last month between July 17 and November 30, 2020. Reports of changes in frequency of engagement in sex work since the pandemic were also collected. RESULTS: Of the 864 individuals included in this analysis, 55 (6.4%) reported sex work engagement in the last month. Among these participants, 40.7% reported receiving COVID-19 income support in the past month vs. 52.7% of the rest of the sample, though receipt of income support in the past six months was similar between the two groups (72.2% vs. 75.7%, p = 0.624). In multivariable analysis, receipt of financial support in the last month was negatively associated with engagement in sex work in the last month (adjusted odds ratio [AOR] = 0.44 [95% confidence interval [CI]: 0.24-0.81]). Among 69 participants who responded to a question regarding changes in engagement in sex work, 38 (55.1%) reported a decrease, 11 (15.9%) reported an increase, 19 (27.5%) reported no change, and 1 (1.4%) reported cessation. CONCLUSIONS: Findings document that engagement in sex work appears to have declined early in the pandemic. Participants who received income support in the past month were less likely to report recent engagement in sex work. Findings suggest that recent receipt of income support may have contributed to reductions in engagement in sex work. Additional investigation is warranted.

RESUMO

OBJECTIVE: Condom use behaviours are proximal to recent STI increases in the USA, yet it remains unclear whether the use of condoms has changed over time among unmarried, non-cohabiting young men who have sex with women (MSW) and how this variability is influenced by STI risk factors. METHODS: To examine condom use over time among MSW aged 15-29, we used three cross-sectional surveys from the 2002, 2006-2010 and 2011-2017 National Survey of Family Growth. We estimated weighted percentages, adjusted prevalence ratios (APRs) and 95% confidence intervals (CI) to assess changes in condom use, stratified by whether MSW reported any STI risk factors in the past 12 months (ie, perceived partner non-monogamy, male-to-male sex, sex in exchange for money or drugs, sex partner who injects illicit drugs, or an HIV-positive sex partner). RESULTS: We observed a divergence in trends in condom use at last sex between men aged 15 -29 with STI risk factors in the past 12 months and those without such history. We saw significant declines in condom use from 2002 to 2011-2017 among men with STI risk factors (APR=0.80, 95% CI 0.68 to 0.95), specifically among those aged 15-19 (APR=0.73, 95% CI 0.57 to 0.94) or non-Hispanic white (APR=0.71, 95% CI 0.54 to 0.93). In contrast, trends in condom use among men with no STI factors remained stable or increased. Across all time periods, the most prevalent STI risk factor reported was perception of a non-monogamous female partner (23.0%-26.9%). Post-hoc analyses examined whether condom use trends changed once this variable was removed from analyses, but no different patterns were observed. CONCLUSIONS: While STIs have been increasing, men aged 15-29 with STI risk factors reported a decline in condom use. Rising STI rates may be sensitive to behavioural shifts in condom use among young MSW with STI risk factors.

RESUMO

OBJECTIVES: We examined data collected as part of the fifth round of integrated biological and behavioural surveillance to determine the prevalence and factors associated with HIV infection among female sex workers (FSWs) in Pakistan. METHODS: FSWs were defined as 'all females, age 13 years and above, who receive money or goods in exchange for sexual services, regardless of the site of operation'. Data were collected between October 2016 and January 2017 in 18 cities using multistage sampling techniques to randomly select FSWs from spots facilitated by peers. Behavioural data were collected by interviewers using structured questionnaires, which was followed by obtaining finger prick blood samples tested for HIV using two rapid tests. Multivariate logistic regression analysis was done to assess independent associations of potential correlates using HIV status as dependent variable. RESULTS: We invited 5728 FSWs to participate, of which 68 refused to participate (refusal rate=1.2%). Of the 5660 FSWs who participated, 121 were HIV seropositive (weighted HIV prevalence 2.3%; 95% CI 1.9% to 2.7%) mostly concentrated within cities in Sindh. Multivariate analysis showed being uneducated/illiterate (adjusted OR (aOR) 2.1; 95% CI 1.4 to 3.4), directly dealing with clients without a pimp (aOR 1.8; 95% CI 1.1 to 2.8), non-use of condom with clients (aOR 1.8; 95% CI 1.1 to 2.8), having sexual contact with people who inject drugs (PWID) (aOR 2.2; 95% CI 1.3 to 3.7) and non-participation in HIV programmes (aOR 1.7; 95% CI 1.0 to 3.1) as factors independently associated with HIV seropositivity. CONCLUSIONS: We found a weighted national HIV prevalence of 2.3% and identified factors independently associated with HIV in FSWs. The country needs to scale up HIV prevention programmes to improve coverage, prioritising FSWs who are illiterate, work independently and have PWID as sex partners. Emphasis should be laid on strategies to improve condom use with both regular and non-regular partners.

RESUMO

OBJECTIVES: Recommendations of 'social distancing' and home quarantines to combat the global COVID-19 pandemic have implications for sex and intimacy, including sex work. This study examined the effects of COVID-19 on male sex work globally and investigated how men who sold sex responded to and engaged with the virus in the context of work. METHODS: This study made use of an existing database of deidentified data extracted from the online profiles maintained by male sex workers on a large, international website. Website engagement metrics were calculated for the periods before (September to December 2019) and during COVID-19 (January to May 2020); Poisson regression analyses were used to assess changes over time before and after, while a content analysis was undertaken to identify modes of engagement with the virus. RESULTS: Data were collected from 78 399 profiles representing 19 388 individuals. In the 'before' period, the number of active profiles was stable (inter-rate ratio (IRR)=1.01, 95% CI 0.99 to 1.01, p=0.339) but during COVID-19 decreased by 26.3% (IRR=0.90, 95% CI 0.89 to 0.91, p<0.001). Newly created profiles also decreased during COVID-19 (59.4%; IRR=0.71, 95% CI 0.69 to 0.74, p<0.001) after a period of stability. In total, 211 unique profiles explicitly referenced COVID-19; 185 (85.8%) evoked risk reduction strategies, including discontinuation of in-person services (41.2%), pivoting to virtual services (38.9%), COVID-19 status disclosure (20.9%), enhanced sanitary and screening requirements (12.3%) and restricted travel (5.2%). Some profiles, however, seemed to downplay the seriousness of COVID-19 or resist protective measures (14.7%). CONCLUSIONS: These findings support the contention that COVID-19 has dramatically impacted the sex industry; globally, male sex workers may be facing considerable economic strain. Targeted education and outreach are needed to support male sex workers grappling with COVID-19, including around the most effective risk reduction strategies. Those involved with the sex industry must have access to state-sponsored COVID-19 financial and other aid programmes to support individual and public health.

RESUMO

In rural China there is an abnormally high male-biased sex ratio. The result is a large number of involuntary bachelors. This study examines how migration and social networks relate to bachelors' sexual risk behaviors. Data are from a cross-sectional questionnaire survey in which 740 male respondents who had rural household registration, had never married, and were aged 28 or older were interviewed in 2017. Logistic regression reveals that both migration and social networks place the bachelors at an especially high risk of HIV transmission by increasing the chance that they engage in commercial sex, whereas only social networks are significantly associated with sexual partnership concurrency. Additionally, social networks mediate the association between migration and commercial sex. This suggests that social networks play an important role in bachelors' risk of HIV transmission and that further intervention should address their social networks.

RESUMO

BACKGROUND: Transgender women (trans women) in Nepal are underserved in the HIV response. Data are needed to determine the HIV prevalence disaggregated from other key populations and to identify the particular risks faced by this community. Trans women are marginalized around the world and research is also needed to determine the impact of stigma on HIV risk to inform trans-specific interventions. METHODS: In 2019, we conducted the first population-based HIV behavioral surveillance study of trans women disaggregated from other key populations using respondent driven sampling (RDS). We estimated the HIV prevalence for trans women, and bivariate and multivariate Poisson binomial regression models were constructed to examine the relationship between HIV risk and stigma. RESULTS: Trans women participants (N = 200) had a mean age of 33 years old (SD = 10.96). We found a weighted HIV prevalence of 11.3% (95% CI 6·82% - 18·13). We found that depression and anxiety (aPR 0.81; 95% CI 0.67-0.97; p = 0·02) and current engagement in sex work (aPR 1.31; 95% CI 1.01-1.71; p = 0·046) were significantly associated with greater prevalence of condomless receptive anal intercourse. We found that experienced stigma of ever being verbally abused due to gender identity was significantly associated with lower prevalence of depression and anxiety (aPR 0.42; 95% CI 0.20-0.87; p = 0·002). Feeling unaccepted in Nepali society and believing people thought they were a criminal because of their trans identity was significantly associated greater prevalence of current sex work (aPR 1.36; 95% CI 1.03-1.78; p = 0·03; aPR 1.45; 95% CI 1.03-2.07; p = 0.04). Every measure of experienced stigma assessed was significantly associated with greater prevalence of current engagement in sex work. CONCLUSIONS: Trans women are highly stigmatized in Nepal, leading to individual and systems factors that impact their risk for HIV. Interventions are needed that support the economic and mental wellbeing of trans women to prevent their heighted risk of HIV from stigma.

RESUMO

BACKGROUND: Research has paid limited attention to understanding factors that are associated with unmet contraceptive needs among female sex workers. In order to fill this knowledge gap, we estimated the prevalence of unmet contraceptive needs and examined associated factors among FSWs in semi urban Blantyre, Malawi. METHODS: We used systematic sampling to recruit 290 female sex workers in semi urban Blantyre between February and March 2019. In this cross sectional study, we used questionnaire interviews to collect quantitative data. We calculated the mean and standard deviation for continuous variables and proportions for categorical variables to describe the data. Logistic regression analysis was used to investigate the association between unmet needs (the outcome variable) and explanatory variables such as: having a steady partner, fear of contraceptives' side effects and having a history of sexually transmitted infections. RESULTS: Out of the 290 study participants 102 (35.2%) reported unmet contraceptive needs. The following factors were significantly associated with unmet contraceptive needs in multivariate analysis: female sex workers' history of physical and sexual violence by clients [OR 3.38, 95% CI (1.10, 10.43)], p < 0.03, participants with a steady partner [OR 3.28, 95% CI (1.89, 5.68)], p < 0.001, and participants who feared side effects of contraceptives [OR 2.99, 95% CI (1.73, 5.20)], p < 0.001. CONCLUSION: Reproductive Health services should address barriers to contraceptives use for instance: violence by female sex workers' clients, fear and misinformation on contraceptives. There is need to improve awareness of contraceptives. Specific health promotion interventions on female sex workers engaged in a steady partnership are recommended. It is important to enhance the knowledge, attitudes, and counseling skills of health care providers in order to address unmet contraceptive needs among female sex workers in semi-urban Blantyre. Unmet contraceptive needs are defined as lack of contraceptives use in heterosexually active women of childbearing age who do not wish to become pregnant. Unmet contraceptive needs are the main cause of short inter-pregnancy intervals, early childbearing, physical abuse, unintended pregnancy, poor maternal and child health outcomes. Several studies have documented low contraceptives use among female sex workers (FSWs), but research has paid limited attention to understanding factors associated with unmet contraceptive needs among this population in semi urban Blantyre Malawi. In order to fill this knowledge gap, we estimated the prevalence of unmet contraceptive needs and examined factors that were associated with unmet contraceptive needs among FSWs in semi urban Blantyre, Malawi. We recruited 290 FSWs and collected quantitative data. These data were analyzed to obtain descriptive statistics. Logistic regression analysis was used to investigate the association between unmet contraceptive needs (the outcome variable) and explanatory variables such as: FSWs with history of physical and sexual violence by clients, having a steady partner, fear of contraceptives' side effects and having a history of sexually transmitted infections. Out of the 290 FSWs, 35% reported unmet contraceptive needs. The following factors were significantly associated with unmet contraceptive needs in multivariate analysis: FSWs' history of physical and sexual violence by clients, participants with a steady partner and participants who feared contraceptive side effects. Sexual and Reproductive Health services should address barriers to contraceptives use, female sex workers exposure to violence, having a steady partners and concerns about side effects. There is also a need to improve the knowledge, attitudes, and counseling skills of health providers in order to address unmet contraceptive needs among FSWs.

RESUMO

OBJECTIVES: Within the context of rising rates of reportable STIs in the USA, we used national survey data to examine temporal trends in high-risk factors that indicate need for STI/HIV preventive services among key subpopulations with disproportionate STI rates. METHODS: We used data from the 2002 (n=12 571), 2006-2010 (n=22 682) and 2011-2015 (n=20 621) National Survey of Family Growth (NSFG). NSFG is a national probability survey of 15-44 year olds living in US households. We examined STI risk factors among sexually active men who have sex with men (MSM) and Hispanic, non-Hispanic black, 15-19 year old, 20-24 year old, and 25-29 year old women who have sex with men (WSM) and men who have sex with women (MSW). Risk behaviours included: received money or drugs for sex, gave money or drugs for sex, partner who injected drugs, partner who has HIV, non-monogamous partner (WSM, MSW only) and male partner who had sex with other men (WSM only). Endorsement of any of these behaviours was recoded into a composite variable focusing on factors indicating increased STI risk (yes/no). We used chi-squares and logistic regression (calculating predicted marginals to estimate adjusted prevalence ratios (aPRs)) to examine STI risk factors over time among the key subpopulations. RESULTS: From 2002 to 2011-2015, reported STI risk factors did not change or declined over time among key subpopulations in the USA. In adjusted analyses comparing 2002 to 2011-2015, we identified significant declines among WSM: Hispanics (aPR=0.84 (0.68-1.04), non-Hispanic blacks (aPR=0.69 (0.58-0.82), adolescents (aPR=0.71 (0.55-0.91) and 25-29 year olds (aPR=0.76 (0.58-0.98); among MSW: Hispanics (aPR=0.53 (0.40-0.70), non-Hispanic blacks (aPR=0.74 (0.59-0.94) and adolescents (aPR=0.63 (0.49-0.82); and among MSM (aPR=0.53 (0.34-0.84). CONCLUSIONS: While reported STIs have increased, STI risk factors among key subpopulations were stable or declined. Condom use related to these risk factors, sexual mixing patterns and STI testing should be examined.

RESUMO

OBJECTIVES: Whether regular HIV testing and counselling reduce risky sexual behaviours in African men who have sex with men (MSM) is still a matter for debate. We aimed to identify behavioural trajectories based on HIV risk exposure (HRE) and factors affecting their evolution. METHODS: Data were collected from 621 HIV-negative West African MSM (Mali, Cote d'Ivoire, Burkina Faso and Togo) included in a community-based cohort providing quarterly HIV testing and counselling. Sociobehavioural data were collected every 6 months. HRE was defined as reporting inconsistent condom use during receptive anal sex with male partners of unknown HIV status in the previous 6 months. Using 18-month follow-up data, group-based trajectory modelling helped identify behavioural trajectories and determine the factors associated with their evolution. HIV seroconversions (n=67) were specified in each group trajectory. RESULTS: Two distinct group trajectories were identified: medium-risk exposure MSM (ME-MSM) (61%, 6.4% of whom having seroconverted) and high-risk exposure MSM (HE-MSM) (39%, 17.5% of whom having seroconverted). A significant declining trend in the probability of reporting HRE over time ((95% CI)) was observed for HE-MSM (from 0.59 (0.48 to 0.70) at M0 to 0.31 (0.22 to 0.41) at M18), while it remained constant for ME-MSM (0.034 (0.0 to 0.079)). This can be explained by a progressive use of risk reduction strategies (less receptive anal sex, better knowledge of their partners' status and increasing condom use). Being younger, living in Burkina Faso, self-considering both a man and a woman and reporting a higher level of depression were all associated with HE membership. Among HE-MSM, HRE was higher in those practising transactional or group sex and those experiencing psychological harassment. CONCLUSIONS: Quarterly HIV testing and counselling seem to reduce risky sexual behaviours in HIV-negative MSM at greatest risk of infection. Specific support for young MSM, focusing on identity and mental health, is needed to strengthen HIV prevention in West African MSM.

RESUMO

BACKGROUND: Black men who have sex with men (BMSM) are disproportionately affected by sexually transmitted infections (STI), including chlamydia and gonorrhea. Transactional sex is an hypothesized risk factor for STI acquisition in BMSM. METHODS: We estimated the association of transactional sex with incident chlamydia/gonococcal infection among BMSM using longitudinal data from a randomized trial in Atlanta (2012-2015). BMSM were eligible for inclusion if they tested human immunodeficiency virus (HIV)-antibody-negative and reported both ≥2 male sex partners and any condomless anal sex in the last year. We defined chlamydia/gonorrhea incidence as the first occurrence of either rectal or urogenital chlamydia or gonococcal infections after a negative result at enrollment. We used Poisson regression to estimate the incidence rate (IR) for chlamydia/gonorrhea over 12 months. Incidence rate ratios (IRR) compared estimates by reported experience of transactional sex. Subgroup analyses assessed potential heterogeneity by age and sexual identity. RESULTS: This analysis included 416 BMSM, of whom 191 (46%) were gay-identified, 146 (42%) reported a history of transactional sex, and 57 (14%) had prevalent chlamydia/gonococcal infection at baseline. Over a median of 1 year of follow-up, an additional 55 men tested laboratory-positive for chlamydia/gonorrhea (IR, 17.3 per 100 person-years). Transactional sex was not associated with chlamydia/gonorrhea incidence overall. However, among gay-identified BMSM, transactional sex was associated with incident chlamydia/gonorrhea (IRR, 2.9; 95% confidence interval, 1.2-6.8). CONCLUSIONS: Economic and social vulnerabilities may motivate engagement in high-risk sexual behaviors through commodified sex, potentially increasing the burden of STIs among BMSM. In this investigation, the relationship between transactional sex and chlamydia/gonorrhea was not homogenous across BMSM with diverse sexual identities in Atlanta, suggesting that within select sexual networks, transactional sex may drive STI risks. Delivering accessible and targeted STI screening for marginalized BMSM should be prioritized for STI and HIV prevention.

RESUMO

OBJECTIVES: Male and transgender women sex workers (TSWs) are vulnerable for sexually transmitted infections (STIs) and human immunodeficiency virus (HIV), and substance use might be a relevant contributing factor. We assessed sociodemographic characteristics and substance use among sex workers; divided into 3 groups: Transgender women sex workers, male sex workers who have sex with men only or also with females (MSW-M), male sex workers who have sex with females only (MSW-F). METHODS: A survey on substance use and sexual (risk) behavior was offered during routine STI screening at the Prostitution and Health Centre (P&G292) in Amsterdam. Bacterial STI positivity (chlamydia (including lymphogranuloma venereum), gonorrhea, and/or infectious syphilis), and substance use were compared (χ test, Fisher exact test). RESULTS: From 2014 until 2015, 99 (60.4%) of 164 eligible visitors participated (n = 69 MSW-M [69.7%], n = 15 TSW [15.2%], and n = 15 MSW-F [15.2%]). Transgender women sex workers reported the highest number of sex partners in the previous 6 months (median: MSW-M 60 vs. TSW 300 vs. MSW-F 12; P < 0.001). The 3 groups did not differ in having condomless anal or oral sex. Bacterial STI positivity was 29.0% in MSW-M, 26.7% in TSW, and 13.3% in MSW-F (P = 0.56). Three new HIV infections were diagnosed, all in MSW-M, whereas 20.3% of MSW-M and 20.0% of TSW were known HIV-positive compared with none of MSW-F (P = 0.14). Illicit substance use during working time in <6 months was 40.5% among MSW-M, 40.0% among TSW, and 20.0% among MSW-F (P = 0.02). The most reported reason for substance use was: "sex work becomes physically easier." CONCLUSIONS: Bacterial STI positivity and illicit substances use during work were high in all 3 sex worker groups, emphasizing the importance of combined and targeted interventions. In-depth qualitative research is needed to better understand intentions and reasons for substance use.

RESUMO

PURPOSE OF REVIEW: This review aims to describe the epidemiology of HIV among female sex workers (FSWs) in China over the past decade, to summarize current gaps in knowledge regarding risk factors, and to identify new directions for HIV prevention strategies. RECENT FINDINGS: We summarized national and regional levels of HIV prevalence among FSWs based on reported rates in the literature from 2008 to 2018. Studies identified cases of HIV infection among FSWs in all but one province during this time period, and demonstrated a sporadic pattern in most provinces, with a low overall national HIV prevalence below 1%. However, in Yunnan and Guanxi Zhuang Autonomous Regions, the median-reported prevalence rates were close to or slightly above 1%. National prevention programs have widely promoted male condoms as a primary and practical measure for HIV prevention, but studies evaluating condom use practices among FSWs demonstrated wide variability. A rise in illicit use of synthetic drugs and changing sexual practices in the setting of sex work (e.g., anal sex) may represent newer risk factors for HIV transmission among FSWs; however, more data are needed to better characterize these trends. Limited studies have examined the feasibility and efficacy of innovative prevention tools (e.g., female condoms) or strategies (e.g., pre-exposure prophylaxis, PrEP) to prevent HIV among FSWs. We call for a more comprehensive understanding of current trends in HIV risk among FSWs, as well as more research focuses on innovative strategies to reduce the spread of HIV in this vulnerable population.

RESUMO

A dearth of empirical research exists on female sex workers in Central America who begin selling sex under age 18. Data were collected from adult female sex workers (N = 1216) sampled using census and modified time-location sampling in three urban centers of Guatemala. In adjusted analyses, female sex workers who entered the sex trade under age 16 years were more likely to be HIV positive (AOR = 4.6, 95% CI 1.6, 13.2), have not received HIV education in their first year of sex trade (AOR = 2.8, 95% CI 1.5, 5.5), have experienced violence to force commercial sex (AOR = 4.6, 95% CI 2.2, 9.8) and have not used condoms in their first month (AOR = 2.8, 95% CI 1.3, 6.1) , relative to those who entered as adults. An interaction between age at entry and foreign migration at entry was found for HIV risk. Efforts to prevent adolescent sex trade entry are needed and may also help to reduce HIV rates in Guatemala.

RESUMO

Few studies have explored the relationship between transactional sex and HIV in adult men, with even fewer exploring the predictors of providing money or goods in exchange for sex. This study aimed to characterise the predictors and patterns of transactional sex in adult men in an urban informal area in South Africa. We used baseline, cross-sectional data from a study of 2406 men aged 18-40 years from an urban informal area. Past year transactional sex was assessed through questions adapted from those used previously. Controlling behaviour was measured using an adapted Sexual Relationship Power Scale. Multivariable logistic regression was used to determine associations between transactional sex and other potential explanatory variables. Nearly half (47%) of respondents who had ever had sex reported at least one type of transactional sex with a casual partner in the past year. A third of men provided support or money for a sex partner's family, 30% provided cash and 28% provided somewhere to stay. Controlling for other factors, men with higher levels of controlling behaviour had nearly double the odds of engaging in transactional sex. Men reporting three or more sexual partners had significantly higher odds of engaging in transactional sex. Hazardous drinkers had 33% higher odds of engaging in transactional sex. Men's provision of money or goods in exchange for sex with women is related to other high-risk behaviours, such as multiple sexual partners, hazardous drinking and controlling behaviour. To address transactional sex-related HIV risks, programming should address harmful masculinities, including relationship control.

RESUMO

In the United States, high rates of HIV infection among persons who engage in transactional sex are partially driven by substance use. Little is known about transactional sex among rural populations of people who inject drugs (PWID). Using data from a 2018 survey of 420 rural PWID in West Virginia, we used logistic regression to identify correlates of recent transactional sex (past 6 months). Most study participants were male (61.2%), white (83.6%), and reported having injected heroin (81.0%) in the past 6 months. Nearly one-fifth (18.3%) reported engaging in recent transactional sex. Independent correlates of transactional sex were: being female [adjusted odds ratio (aOR) 3.90; 95% CI 2.12-7.16]; being a sexual minority (aOR 3.07; 95% CI 1.60-5.87); being single (aOR 3.22; 95% CI 1.73-6.01); receptive syringe sharing (aOR 3.13; 95% CI 1.73-5.66); and number of injections per day (aOR 1.08; 95% CI 1.01-1.15). Rural PWID who engage in transactional sex are characterized by multiple vulnerabilities that increase their HIV risk.

RESUMO

Exposure to sexual risk in early adolescence strongly predicts HIV infection, yet evidence for prevention in young adolescents is limited. We pooled data from two longitudinal South African surveys, with adolescents unexposed to sexual risk at baseline (n = 3662). Multivariable logistic regression tested associations between intermittent/consistent access to eight provisions and reduced sexual risk exposure. Participants were on average 12.8 years, 56% female at baseline. Between baseline and follow-up, 8.6% reported sexual risk exposure. Consistent access to caregiver supervision (OR 0.53 95%CI 0.35-0.80 p = 0.002), abuse-free homes (OR 0.55 95%CI 0.37-0.81 p = 0.002), school feeding (OR 0.55 95%CI 0.35-0.88 p = 0.012), and HIV prevention knowledge (OR 0.43, 95%CI 0.21-0.88 p = 0.021) was strongly associated with preventing early sexual risk exposure. While individual factors reduced the odds of sexual risk exposure, a combination of all four resulted in a greater reduction, from 12.9% (95%CI 7.2-18.7) to 1.0% (95%CI 0.2-1.8). Consistent access to provisions in early adolescence may prevent sexual risk exposure among younger adolescents.

RESUMO

Transactional sex (TS) has been shown to contribute to the HIV epidemic in sub-Saharan Africa. Previous research has yet to identify psychosocial factors that make young women vulnerable to engaging in TS. This analysis examined the association between self-esteem and TS among young women in rural South Africa. A post hoc analysis of post-intervention survey data from HPTN 068 was conducted. Log-binomial regression was used to compute a prevalence ratio measure of association. Among 1942 young women, the prevalence of TS among those with lower self-esteem was 4.7 times the prevalence of TS among those with higher self-esteem (p < 0.001). Findings provide support for the association between lower self-esteem and TS in this context and may inform intervention development.
