Development of a HIV Prevention Program to Promote Condom Use Among Iranian Female Sex Workers: Application of An Intervention Mapping Approach.

We used an Intervention Mapping Approach (IMA) to derive multi-level HIV prevention strategies aiming to develop an HIV prevention intervention program among female sex workers (FSWs). We also aimed at pilot testing the effects of the IMA-based "HIV Prevention and Awareness Program (HIV-PAP)" on safe sex behaviors and its determinants among FSWs in Tabriz, Iran. To develop HIV-PAP, we conducted the six-step process of IMA. At Step 1, in a cross-sectional study, 140 FSWs were face-to-face interviewed. At Step 2, the program matrix was provided based on the importance and variability for identifying priority factors. At Steps 3 and 4, the methods and strategies for behavioral change were selected, and the HIV-PAP program components and materials were developed. At Steps 5 and 6, evaluation (as a pilot testing with Static-Group Comparison design) was conducted applying a pre-experimental study, in which 30 FSWs were assigned to intervention (n = 15) and control (n = 15) groups. The intervention group participated in a two-month long program, and one month later, the initial questionnaires were completed by both groups. The respondents (M age: 33.4 years, SD: 9.7) acquired low score (less than 50%) in negotiating for condom use (49.8%) only, and moderate scores (50-65%) in perceived social support (61.6%) and knowledge (60.5%). Adjusted for other variables, the factors (R2 = 32.0%) associated with safe sex behaviors among FSWs were predisposing factors [self-efficacy (ß = 0.331), perceived norms (ß = 0.945), and perceived barriers (ß = 0.258)], condom use negotiation (ß = 1.386), and environmental factors (ß = 0.333). Our IM-based framework had an adequate fit index (χ2 = 130.8, CFI = 0.78). Looking for inter-group comparison after intervention, we found significant mean difference (MD) for knowledge (MD: 2.18; 95% Confidence Interval (CI) - .38 to 4.74, p < 0.05), self-efficacy to use condom (MD: 6.71; 95% CI - 1.85 to 9.29, p < 0.05), perceived risk (MD: 2.03; 95% CI 0.58, to 3.49, p < 0.05), perceived social support (MD: 4.64; 95% CI - 5.37 to 11.31, p < 0.01), and safe sexual behaviors (MD: 7.75; 95% CI - 4.19 to 9.71, p < 0.05). The HIV-PAP showed effectiveness in promoting safe sexual behaviors and their determinants among FSWs. Healthcare providers should better understand the determinants of safe sexual behaviors among FSWs in the settings with legal prohibitions for sex work. In such communities, they should try to either develop or adapt such stage-specific interventions, within which promoting the above-mentioned factors is the core priorities of the program.

"I'd Rather Use a Refuse Bag:" A Qualitative Exploration of a South African Community's Perceptions of Government-Provided Condoms and Participant-Preferred Solutions.

Despite South Africa experiencing one of the largest HIV epidemics in the world, condom use has decreased since 2008. However, condoms are the only low-cost HIV prevention technology widely available in South Africa. This study aims to explore a South African community's perceptions of condoms, recent condom use decrease, and suggestions for increasing condom use. In 2014, we conducted seven focus groups (n = 40 men) and 20 in-depth interviews (n = 9 men, n = 11 women) with participants aged ≥ 18 years recruited from four urban settlement health clinics in Cape Town, South Africa. Data were collected, coded, and analysed using a general inductive approach. Participants perceived government-provided condoms negatively, with themes including "disgust" for condom physical properties, concerns with social status associated with free condoms, and performance concerns. There was an intersection of themes surrounding masculinity, condom use, and sexual pleasure. Solutions to increase condom use included improving the quality and variety of free condoms and rebranding free condoms. Participants suggested that condoms are distributed with novel attributes (e.g., more colors, smells/flavors, sizes, and in-demand brands) and that government programs should consider offering all brands of condoms at no or low cost. This study suggests a substantial rethinking of condom branding for government-provided condoms. Our findings suggest that condom dissemination and promotion programs should proactively address public concerns regarding condoms. Existing societal and structural norms such as hegemonic masculinity must also be addressed using gender-transformative interventions. We also strongly suggest the creation of a Male Condom Acceptability Scale to understand condom users' needs.

Association between Psychological Factors and Condom Use with Regular and Nonregular Male Sexual Partners among Chinese MSM: A Quantitative Study Based on the Health Belief Model.

OBJECTIVE: The Chinese men who have sex with men (MSM) population is suffering from a high HIV infection rate owing to unprotected anal sex. The Health Belief Model (HBM) has been proven to be an effective frame associated with behavior maintenance. Based on HBM, we analyzed the beliefs associated with consistent condom use behavior with regular and nonregular partners among MSM to better provide targeted interventions and services. METHODS: A study was conducted in Sichuan Province, China, from November 2018 to April 2019, and 801 eligible participants were recruited by snowball sampling. Sociodemographic characteristics, AIDS-related characteristics, sexual behaviors, condom use behavior, and dimensions of HBM were investigated. Univariate, single multivariate, and summary multivariate models were employed to analyze the factors associated with consistent condom use. RESULTS: Of all participants, 39.1% and 53.6% had had anal sex with regular and nonregular partners in the last six months, respectively. Only 56.5% of them had used condoms consistently with regular partners, and only 60% of them had used condoms consistently with nonregular partners. When taking consistent condoms use with regular partners as the dependent variable, the dimensions of perceived threats (ORM = 1.28, 95% CI: 1.10, 1.49), perceived barriers (ORM = 0.70, 95% CI: 0.60, 0.82), self-efficacy (ORM = 1.23, 95% CI: 1.14, 1.32), and cues to action (ORM = 1.21, 95% CI: 1.02, 1.43) showed significant associations with the dependent variable. When taking consistent condoms use with nonregular partners as the dependent variable, the dimensions of perceived barriers (ORM = 0.77, 95% CI: 0.67, 0.89), self-efficacy (ORM = 1.22, 95% CI: 1.13, 1.32), and cues to action (ORM = 1.53, 95% CI: 1.30, 1.80) showed significant associations with the dependent variable. CONCLUSIONS: More attention should be focused on how to decrease the obstructive factors of condom use, how to improve the confidence of condom use, and how to layout more cues to action to promote consistent condom use behavior with regular and nonregular partners during anal sex among Chinese MSM.

Transitions in adolescent boys and young Men's high-risk sexual behaviour in India.

BACKGROUND: The sexual behaviour of adolescents is of importance due to the engagement in risky sexual activity at a too early age, which may be associated with the adverse outcomes. The study aims to understand the transitions in adolescent boys and young men's high-risk sexual behaviour in India using two rounds of Indian demographic health survey, NFHS-3 (2005-06) and NFHS-4 (2015-16). METHODS: A total of 25,538 in NFHS-3 (2005-06) and 35,112 in NFHS-4 (2015-16) men were considered for the analysis. Men have been divided into two age groups as 15-19 years (adolescent) and 20-24 (young men) for comparison purposes. Descriptive and multivariate statistics have been used. RESULTS: Overall, high-risk sexual behaviour has increased among adolescent boys (64 to 70%) and young men (18 to 27%) from 2005-06 to 2015-16. The trend of live-in relationship has increased among adolescent boys of rural areas (0.6 to 6.0%) as well as in urban areas (3.1 to 10.9%) over the last 10 years. Adolescent boys having 10th and above years of schooling (AOR = 1.98; p < 0.01), residing in urban areas (AOR = 2.23; p < 0.01), and belonging to the affluent class of households (AOR = 1.41; p < 0.05) were more likely to engage in high-risk sexual activity than the young men in India. The odds of high-risk sexual behaviour was higher among alcohol-using adolescent boys (AOR = 1.82; p < 0.01) and young men (AOR = 2.38; p < 0.01) in 2015-16. CONCLUSIONS: The study concludes that early sexual debut, lower prevalence of condom use at first sexual experience, tendency of live-in-relationship, and alcohol consumption indicate the hazardous interconnection between such behaviours among adolescent boys over the last decade which placed them at higher-risky sexual behaviour as compared to young men. Adolescent' sexual behaviours have both short-term and long-term consequences, and interventions that focus on multiple domains of risk may be the most effective in helping to promote broad reproductive health among young adults.

Socio-demographic characteristics and risk factors for HIV transmission in female bar workers in sub-Saharan Africa: a systematic literature review.

BACKGROUND: Although sex workers are considered a key population in the HIV epidemic in sub-Saharan Africa (SSA), less consideration has been given to female bar workers (FBW), whose primary occupation is not sex work but who often engage in transactional sex. Understanding FBWs' risk profiles is central to designing targeted HIV prevention interventions for them. This systematic review describes the socio-demographic characteristics and risk factors for HIV transmission among FBWs in SSA. METHODS: We searched six databases: PubMed, Google Scholar, Web of Science, Popline, Embase and additionally the World Health Organization's WHOLIS database for grey literature between July and September 2017. Inclusion criteria were reporting (1) primary socio-demographic or behavioral data; on (2) women who sold or delivered drinks to clients; (3) in establishments serving alcohol; (4) in SSA. We excluded studies not presenting separate data on FBWs. We extracted quantitative and qualitative data from the selected studies and conducted a qualitative synthesis of findings. RESULTS: We found 4565 potentially eligible articles, including duplicates. After applying inclusion and exclusion criteria, we retained 19 articles. FBWs often migrated from rural to urban areas due to economic need or social marginalization. They began bar-based transactional sex due to low wages, peer pressure and to increase financial independence. FBWs had high HIV risk awareness but low agency to negotiate condom use, particularly with regular partners or when offered higher prices for condomless sex. FBWs were also vulnerable to violence and stigmatization. CONCLUSIONS: FBWs are a vulnerable population for HIV infection. Despite social stigmatization and elevated risk of contracting STIs, bar work remains attractive because it enables unskilled women to both, make a living and maintain some independence. FBWs face HIV-related risk factors at the individual, community and societal level and may benefit from biomedical, behavioral and structural interventions.

Enhancing financial security of female sex workers through a community-led intervention in India: Evidence from a longitudinal survey.

INTRODUCTION: Community-led organizations (COs) have been an integral part of HIV prevention programs to address the socio-economic and structural vulnerabilities faced by female sex workers (FSWs). The current study examines whether strengthening of community-led organizations and community collectivization have been instrumental in reducing the financial vulnerability and empowering FSWs in terms of their self-efficacy, confidence, and individual agency in India. DATA AND METHODS: This study used a panel data of 2085 FSWs selected from 38 COs across five states of India. Two rounds of data (Round 1 in 2015 and Round 2 in 2017) were collected among FSWs. Data were collected both at CO and individual level. CO level data was used to assess the CO strength. Individual level data was used to measure financial security, community collectivization, and individual empowerment. RESULTS: There was a significant improvement in CO strength and community collectivization from Round 1 to Round 2. High CO strength has led to improved financial security among FSWs (R2: 85% vs. R1: 51%, AOR: 2.5; 95% CI: 1.5-4.1) from Round 1 to Round 2. High collective efficacy and community ownership have improved the financial security of FSWs during the inter-survey period. Further, the improvement in financial security in the inter-survey period led to increased or sustained individual empowerment (in terms of self-confidence, self-efficacy, and individual agency) among FSWs. CONCLUSIONS: Institutional strengthening and community mobilization programs are key to address the structural issues and the decrease of financial vulnerability among FSWs. In addition, enhanced financial security is very important to sustain or improve the individual empowerment of FSWs. Further attention is needed to sustain the existing community advocacy and engagement systems to address the vulnerabilities faced by marginalized populations and build their empowerment.

Delivering community-led integrated HIV and sexual and reproductive health services for sex workers: A mixed methods evaluation of the DIFFER study in Mysore, South India.

INTRODUCTION: Women in developing countries continue to face barriers to accessing sexual and reproductive health (SRH) services, with marginalized women facing increased challenges to accessing care. The Diagonal Interventions to Fast-Forward Enhanced Reproductive Health (DIFFER) project implemented a package of interventions for female sex workers and women from the general population which integrated horizontal health services for the general population with existing vertical targeted interventions aimed at sex workers with an aim to improve SRH and HIV services. We present an outcome evaluation of the DIFFER project in terms of uptake rates for SRH services among sex workers in Mysore, India. METHODS: Ashodaya Samithi, a sex worker-led organization, implemented the DIFFER strategy through their community-based clinic and a Well Women Clinic (WWC), established at a partner private hospital that provided SRH services for women living with HIV. Mixed methods were used to evaluate the intervention that included a baseline (2012-13) and end of project (2015-16) cross sectional surveys (CSS), focus group discussions (FGDs), key informant interviews, and analysis of service statistics from 2013-2016. RESULTS: The CSS found that condom use, STI testing, and treatment were high before, and throughout the intervention; cervical cancer screening and treatment increased significantly, from 11.5% to 56% (aOR 9.85, p<0.001) and HIV testing in the last 3 months increased from 26.3% to 73.3% (aOR 7.25, p<0.001). The proportion of sex workers using any SRH service in the past year doubled from 25.7% to 51.4% (aOR 2.91, p<0.001). Service statistics showed similar trends. The FGDs and key informant interviews showed that women and stakeholders held high levels of satisfaction with the strategy, and affirmed potential for scale up. CONCLUSION: The DIFFER strategy demonstrated that SRH service uptake can occur in conjuction with HIV services offered to sex workers. This model of integrated service delivery has been accepted by policy makers and needs further analysis for scaling up.

Implementation Strategies to Increase PrEP Uptake in the South.

PURPOSE OF REVIEW: Seven years after TDF/FTC was approved for pre-exposure prophylaxis to reduce risks of HIV infection, there have been large increases in the number of persons using PrEP in the USA. However, recent data on pre-exposure prophylaxis (PrEP) use at the state level indicate that people living in the Southern United States are underserved by PrEP relative to their epidemic need. We sought to review possible reasons for inequitable uptake of PrEP in the South and identify implementation approaches to increase PrEP uptake in the South. RECENT FINDINGS: Published literature, data on the locations of PrEP service providers, recent data on PrEP utilization from pharmacy prescription databases, HIV surveillance data and government data on healthcare providers, and health literacy indicate a confluence of factors in the South that are likely limiting PrEP uptake. A variety of approaches are needed to address the complex challenges to PrEP implementation in the South. These include considering alternative PrEP provision strategies (e.g., pharmacy-based PrEP, telemedicine-delivered PrEP), conducting gain-based stigma-reduction campaigns, increasing capacity for reimbursement for PrEP medications and services through policy change to expand Medicaid and to preserve access to Affordable Care Act-compliant health plans, expanding STI screening programs and improving integration of PrEP offering with delivery of positive STI results, using mHealth tools to screen groups at highest risk for HIV (e.g., men who have sex with men) periodically to increase correct perception of risk, and streamlining clinical procedures to allow same-day PrEP starts for patients without obvious medical contraindications. Overcoming the structural, capacity, and policy challenges to increasing PrEP uptake in the South will require innovations in clinical approaches, leveraging technologies, and policy changes. The South has unique challenges to achieving equitable PrEP uptake, and addressing key barriers to expanded PrEP use will require multisectoral responses.

African-American sexual minority adolescents and sexual health disparities: An exploratory cross-sectional study.

PURPOSE: To better understand sexual health disparities among African-American sexual minority adolescents. METHODS: African-American adolescents (N = 1120; mean age = 15.24 years) were recruited from 4 cities (Columbia, SC; Macon, GA; Providence, RI; Syracuse, NY) to a larger trial. The current analyses used data from the 18-month follow-up when adolescents reported on their sexual partnerships, condom use knowledge, self-efficacy and outcome expectancies for condom use, sexual risk behavior, and STI testing history. RESULTS: Compared with heterosexual adolescents, sexual minority adolescents reported more concerns about potential relationship harms resulting from safer sex negotiation. Sexual minority adolescents were also more likely to engage in riskier sexual behaviors, with females reporting more sexual partners and drug use prior to sex, and males reporting inconsistent condom use and higher rates of HIV. CONCLUSIONS: African-American sexual minority adolescents evidence disparities in sexual risk behavior and STI history that appear to result from interpersonal and relationship concerns. These concerns need to be targeted in sexual health interventions for sexual minority adolescents.

Behavioral economics-based incentives supported by mobile technology on HIV knowledge and testing frequency among Latino/a men who have sex with men and transgender women: Protocol for a randomized pilot study to test intervention feasibility and acceptability.

BACKGROUND: Mobile Technology and Incentives (MOTIVES) is a randomized pilot study of a mobile technology-based and behavioral economics-supported HIV prevention intervention. Behavioral economics (BE) uses financial incentives in a way that departs from the traditional focus on large monetary payments. Instead, BE suggests that relatively small "nudges" can effectively initiate and sustain behavior change. This pilot study examines the feasibility and acceptability of an HIV prevention intervention that uses text messages in combination with BE incentives to improve retention of HIV prevention information and increase frequency of HIV testing among Latino/a men who have sex with men (MSM) and transgender women (TGW). The pilot will also estimate mission-critical design parameters with point and confidence interval estimates of the intervention to inform a future, fully powered effectiveness study. METHODS: The project will be conducted in collaboration with Bienestar Human Services, Inc. (Bienestar), a non-profit community-based service organization. The intervention is being tested in a small, randomized controlled trial to pilot the intervention's feasibility and acceptability among 200 Latino/a MSM and TGW from Bienestar's HIV testing sites. Information on feasibility will include recruitment, refusal, and retention rates as well as message sending success rates; acceptability will include perceived appropriateness based on responses to the intervention. Participants will be randomized into either the "information only" control group (e.g. receiving text messages with HIV prevention information) or the "information plus" intervention group (e.g. additionally receiving quiz questions that provide the possibility of winning prizes). Participants will be followed for 12 months from enrollment. In addition to using data abstracted from Bienestar's routine data collection mechanisms, we will also collect survey data (blinded outcome assessment) from participants at 0, 6, and 12 months to provide an initial assessment of whether incentives affect their level of HIV knowledge and testing frequency. DISCUSSION: If shown to be acceptable, feasible, and resource-efficient, MOTIVES will provide an innovative way to communicate the latest HIV prevention information and support trimestral HIV screening among Latino/a MSM and TGW. TRIAL REGISTRATION: ClinicalTrials.gov, NCT03144336 . Registered on 5 May 2017.

Girls cannot be trusted: young men's perspectives on contraceptive decision making and sexual relationships in Bolgatanga, Ghana.

BACKGROUND: There is extensive research on African girls sexual experiences, but much less is known about boys thoughts and actions. There is a need to understand the male perspective in order to develop sexuality education programmes that address the high rates of teenage pregnancy and sexually transmitted infections in sub-Saharan Africa. METHODS: For this qualitative, phenomenological study we spoke to 20 boys from Bolgatanga, Ghana and explored their sexual decision making, using semi-structured interviews designed to highlight psychosocial and environmental factors. Content analysis was used to construct categories and later the themes. RESULTS: Boys often had negative perceptions about sexual relationships. They believed that girls could not be trusted and mostly embarked on sexual relationships for material gain. The boys reported engaging in multiple sexual partnerships to secure their masculine status; however, they expected girls to be 'faithful'. We found that accurate knowledge of safe sex was lacking, boys were under peer pressure to conform to beliefs about masculinity and communication about sex mainly took place within peer groups. CONCLUSIONS: There is a need to emphasise condom use in established relationships. There should also be more discussion of issues surrounding fidelity and gender equality, as part of sexuality programmes aimed at boys in Ghana and in similar cultures.

Efficacy of a Small-Group Intervention for Post-Incarcerated Black Men Who Have Sex with Men and Women (MSMW).

We conducted a randomized controlled trial of a six-session behavioral intervention designed to reduce frequency of condomless sex and numbers of sex partners among recently incarcerated, bisexual Black men. One hundred participants were assigned to the small-group intervention, Men in Life Environments (MILE), and 112 were assigned to the control condition. Among those assigned to MILE, 69% attended at least one session, 88% of whom attended all sessions. At 3-months' follow-up, large reductions in risk behaviors were reported by both groups. Means for episodes of condomless sex in the previous 3 months declined from 27.7 to 8.0 for the intervention and 25.6 to 6.7 for the control group. Reductions were not greater for the intervention than those of the control group. Regression to the mean, respondent burden, and implementation issues, such as moving from office-based to field-based survey administration at follow-up, may have contributed to the large declines reported by both groups.

The moderating effect of alcohol use on protective and risky sex behaviors among college students in the Southeast United States.

Objective: College students are a high-risk population for new human immunodeficiency viruses (HIV) diagnoses. Although condom use self-efficacy and HIV knowledge can protect against risky sexual behavior (RSB), these same protective factors have been shown to exacerbate RSB. The influence of alcohol use can further complicate these protective factors to influence RSB. Participants: 689 African American/Black and non-Hispanic White college students attending a public university in the Southeast United States. Method: This study sought to examine the relations between condom use self-efficacy and HIV knowledge with RSB and the moderating effect of alcohol use. Results: Findings showed positive associations between RSB and HIV knowledge and alcohol use. Unexpectedly, low frequency drinkers with high condom use self-efficacy were at increased risk for RSB compared to high frequency drinking counterparts. Conclusions: Findings point to the need to target prevention services for low-risk drinkers in college settings.

Perceived intentional transmission of HIV infection, sustained viral suppression and psychosocial outcomes among men who have sex with men living with HIV: a cross-sectional assessment.

OBJECTIVE: HIV continues to be a global and national public health challenge, and men who have sex with men (MSM) are disproportionately affected in the USA. Transmission of HIV is intentional if the person living with HIV knows about his/her serostatus, acts with the intention to and actually transmits HIV. Research on intentional transmission of HIV infections is lacking, and the relationships between perceived intentional transmission, viral suppression and psychosocial outcomes have not been assessed. The objective of this study was to investigate the association between perceived intentional transmission of HIV, sustained viral suppression and psychosocial outcomes. METHODS: Data were obtained from 338 MSM living with HIV who participated in a disclosure intervention study. Logistic and linear regression models were used to assess the associations between perceived intentional transmission and viral suppression, condomless anal intercourse in the past 30 days, being at risk for clinical depression, substance use, self-efficacies for condom use, HIV disclosure and negotiation of safer sex practices, and sexual compulsivity. RESULTS: 44% of the study population reported perceiving intentional HIV transmission. After adjusting for sociodemographic characteristics, men who thought that they were infected intentionally had 69% higher odds (adjusted OR: 1.69; 95% CI 1.01 to 2.83) of being at risk for clinical depression, and on average, scored approximately 3 points and 4 points higher on depressive symptoms and sexual compulsivity, respectively (adjusted ß: 3.29; 95% CI 0.42 to 6.15; adjusted ß: 3.74; 95% CI 1.32 to 6.17) compared with men who did not think that they were intentionally infected. After adjusting for confounders, there was no statistically significant association between perceived intentional transmission and viral suppression. CONCLUSIONS: Intervention programmes for MSM living with HIV who thought they were infected intentionally are warranted and should aim to attenuate depressive symptoms and sexual compulsivity.

Punto Seguro: A Randomized Controlled Pilot Using Conditional Economic Incentives to Reduce Sexually Transmitted Infection Risks in Mexico.

Randomized controlled pilot evaluated effect of conditional economic incentives (CEIs) on number of sex partners, condom use, and incident sexually transmitted infections (STIs) among male sex workers in Mexico City. Incentives were contingent on testing free of new curable STIs and/or clinic attendance. We assessed outcomes for n = 227 participants at 6 and 12 months (during active phase with incentives), and then at 18 months (with incentives removed). We used intention-to-treat and inverse probability weighting for the analysis. During active phase, CEIs increased clinic visits (10-13 percentage points) and increased condom use (10-15 percentage points) for CEI groups relative to controls. The effect on condom use was not sustained once CEIs were removed. CEIs did not have an effect on number of partners or incident STIs. Conditional incentives for male sex workers can increase linkage to care and retention and reduce some HIV/STI risks such as condomless sex, while incentives are in place.

[Sex workers and public health: intersections, vulnerabilities and resistance]. / Trabajadores del sexo y salud pública: intersecciones, vulnerabilidades y resistencia.

Since the 19th century with syphilis and most recently with AIDS, sex workers have been seen as a means for disease transmission and a public health problem that requires intervention. However, researchers have shown that in Western countries, HIV rates in people involved in commercial sex are low, except for in specific groups, such as intravenous drug users. Moreover, the risks faced by sex workers due to stigmatization and other forms of violence have been put into evidence. Based on an urban ethnography with street sex workers carried out in Porto (Portugal), between 2004 and 2005, this article discusses the social, labor, and legal vulnerabilities affecting people involved in commercial sex and how these interfere with their health. Focus is placed on the strategies used by sex workers to minimize health risks and their discourses of resistance in fighting vulnerabilities.

Condom use peer norms and self-efficacy as mediators between community engagement and condom use among Chinese men who have sex with men.

BACKGROUND: Community engagement strategies are often integrated in public health interventions designed to promote condom use among men who have sex with men (MSM), a key population for HIV prevention. However, the ways in which condom use peer norms and self-efficacy play a role in the association between community engagement and condom use is unclear. This study examines the potential mediating roles of peer norms and self-efficacy in this association. METHODS: A nationwide cross-sectional online survey was conducted among Chinese MSM in 2015. Recruitment criteria included being born biologically male, being older than 16 years, having had anal sex with a man at least once during their lifetime, and having had condomless anal or vaginal sex in the past three months. Mplus 6.11 was used to conduct confirmatory factor analysis and path modeling analysis to examine the structural relationships between HIV/sexual health community engagement (e.g., joining social media and community events related to HIV and sexual health services), condom use peer norms, condom use self-efficacy, and frequency of condom use. RESULTS: The study found that HIV/sexual health community engagement, condom use peer norms, condom use self-efficacy, and frequency of condom use were mutually correlated. A good data model was achieved with fit index: CFI = 0.988, TLI = 0.987, RMSEA = 0.032, 90% CI (0.028, 0.036). HIV/sexual health community engagement was associated with frequency of condom use, which was directly mediated by condom use peer norms and indirectly through self-efficacy. CONCLUSION: The study suggests that condom use peer norms and self-efficacy may be mediators in the pathway between community engagement and condom use, and suggests the importance of peer-based interventions to improve condom use.

Trabajadores del sexo y salud pública: intersecciones, vulnerabilidades y resistencia / Sex workers and public health: intersections, vulnerabilities and resistance

RESUMEN Desde el siglo XIX, con la sífilis y, más recientemente, con el sida, lxs trabajadorxs del sexo pasaron a ser vistos como medios de transmisión de enfermedades y como un problema de salud pública que requiere intervención. Sin embargo, las investigaciones han demostrado que, en los países occidentales, la tasa de VIH en personas involucradas con la venta de sexo es baja, con excepción de grupos específicos, como los consumidores de drogas por vía inyectable. Además, se han puesto en evidencia los riesgos a los que están sometidos lxs trabajadorxs del sexo, por vía de la estigmatización o de otras formas de violencia. En este artículo, a partir de una etnografía urbana con trabajadorxs del sexo de calle, llevada a cabo en la ciudad de Porto (Portugal) entre 2004 y 2005, discutimos las vulnerabilidades sociales, laborales y jurídicas que afectan a las personas involucradas en el comercio del sexo y cómo interfieren en su salud. Nos centraremos en las estrategias de lxs trabajadorxs del sexo para minimizar los riesgos para la salud y el discurso de resistencia en el combate a las vulnerabilidades.

Female sex workers use power over their day-to-day lives to meet the condition of a conditional cash transfer intervention to incentivize safe sex.

Female Sex Workers are a core population in the HIV epidemic, and interventions such as conditional cash transfers (CCTs), effective in other health domains, are a promising new approach to reduce the spread of HIV. Here we investigate how a population of Tanzanian female sex workers, though constrained in many ways, experience and use their power in the context of a CCT intervention that incentivizes safe sex. We analyzed 20 qualitative in-depth interviews with female sex workers enrolled in a randomized-controlled CCT program, the RESPECT II pilot, and found that while such women have limited choices, they do have substantial power over their work logistics that they leveraged to meet the conditions of the CCT and receive the cash award. It was through these decisions over work logistics, such as reducing the number of workdays and clients, that the CCT intervention had its greatest impact on modifying female sex workers' behavior.

Source of Sex Information and Condom Use Intention Among Latino Adolescents.

Adolescence is a common time for sexual initiation and information seeking about sexual health, yet little is known about how adolescents' sources of information about sex influence their sexual beliefs and behaviors. This is particularly true for Latino adolescents, whose sources of sex information and sexual behaviors are vastly understudied. A survey of ninth-grade Latino adolescents ( N = 1,186) was employed to examine the relationship between adolescents' primary source of sex information and their intention to use condoms. The study also examined the potential influences of demographics (age, gender), sociodemographics (socioeconomic status, parent education, and linguistic acculturation), and sexual experience on condom use intention. Among Latino youth, the most commonly reported source of sex information was parents (37.8%), followed by another relative (17.1%), school (13.4%), and friends (11.4%). Hierarchical regression analyses showed that after controlling for other factors, primary source of sex information was significantly associated with condom use intention ( p = .042). Hierarchical regression results stratified by gender showed that this relationship remained significant for males ( p = .004) but not for females ( p = .242). Males who reported friends (odds ratio [ OR] = 0.44, p = .003) or the media/Internet ( OR = 0.44, p = .008) as their primary sources of sex information, as compared to parents as their primary source, reported significantly lower intention to use condoms. These findings suggest it may be important for Latino adolescents, particularly males, to have additional or other sources for sex information in order to promote healthy sexual behaviors. Alternatively, interventions targeting parents or other family members to improve sexual health communication with adolescent boys may prove essential.
