Difference in Risk Behaviors and STD Prevalence Between Street-Based and Establishment-Based FSWs in Guangdong Province,China

The major mode of HIV/AIDS transmission in China is now heterosexual activities, but risk for HIV and sexually transmitted diseases (STDs) may differ among different strata of female sex workers (FSWs). Respondent-driven sampling was used to recruit 320 FSWs in Guangdong Province, China. The respondents were interviewed using a structured questionnaire, and tested for HIV, syphilis, gonorrhea, and Chlamydia. The street-based FSWs had lower education levels, a higher proportion supporting their families, charged less for their services, and had engaged in commercial sex for a longer period of time than establishment-based FSWs. The proportion consistently using condoms with clients and with regular non-paying partners was also lower. The prevalence of syphilis, gonorrhea, and Chlamydia was higher among street-based sex workers. Being a street-based sex worker, having regular non-paying sex partners, and having non-regular non-paying partners were independent risk factors for inconsistent condom. Street-based FSWs had more risk behaviors than establishment-based FSWs, and should therefore be specifically targeted for HIV as well as STD intervention programs.     

Sociocultural Contexts of Access to HIV Primary Care and Participant Experience with an Intervention Project: African American Transgender Women Living with HIV in Alameda County,California

The baseline data of the intervention project for African American transgender women living with HIV showed that more than one-third of the participants having ever enrolled in HIV care had not received ART and that among those in ART, more than half reported their adherence to ART was poor. Those who had engaged in sex work, sold drugs, or experienced higher levels of transphobia were less likely to have enrolled in care. The qualitative interviews with participants who had completed the intervention or dropped out revealed barriers to enroll in care, such as community stigma and transphobia.

     

A Sexual Risk Reduction Intervention for Female Sex Workers in Mexico

Abstract

Female sex workers (FSWs) 18 or older who reported having unprotected sex with at least one client within the previous month were recruited in Tijuana and Ciudad Juarez, Mexico. After a baseline assessment, participants were randomly assigned to either: (1) Proyecto Comparte Sexo Mas Seguro (“Share Safer Sex”), a theory-based counseling intervention to increase the use of condoms; or (2) time-equivalent voluntary HIV counseling and testing.

Participants had unprotected sex with approximately 27% of clients over the one-month reporting period, and approximately 5% of FSWs in both study conditions tested HIV-seropositive. FSWs in the intervention and comparison conditions showed no significant differences in baseline demographic characteristics, sexual risk behaviors, or HIV serostatus, which indicates that randomization was successful. Future challenges entail participant followup and evaluation of intervention effects.     

Condom Negotiation and Use Among Female Sex Workers in Phnom Penh, Cambodia

We examined condom-use negotiation strategies and condom use among 81 female sex workers (FSWs) in Phnom Penh, Cambodia. Percentages of FSWs who did not negotiate condom use or could not describe a negotiation strategy with native clients, foreign clients, and non-paying partners were 15.0, 29.0 and 67.6 %, respectively. The most common negotiation strategy used was “provision of risk information” for native clients (43.8 %) and non-paying partners (26.5 %), and “direct request” for foreign clients (39.5 %). About half could not describe more than one negotiation strategy. Consistent condom use was high with native clients (98.8 %), yet comparatively lower with foreign clients (86.9 %) and non-paying partners (26.5 %). FSWs who did not negotiate or did not know how to negotiate condom use were less likely to report condom use with non-paying regular partners. Future interventions should enhance condom negotiation strategies between FSWs and all partner types.     

Short-term effect of a cultural adaptation of voluntary counseling and testing among female sex workers in China: a quasi-experimental trial.

This study evaluates the efficacy of cultural adaptation of a voluntary counseling and testing (VCT) intervention, in increasing condom use and decreasing rates of sexually transmitted diseases (STDs) among a group of female sex workers (FSWs) in Guangxi, China. This intervention is modeled after the "state-of-the-science" VCT program that was developed and evaluated by the Center for Disease Control and Prevention's Project RESPECT. Four hundred FSWs were assigned to either an intervention group receiving the VCT intervention or a control group receiving standard of care STD testing and treatment. Data were collected at baseline and 6 months postintervention. Outcome measures included HIV/STD related knowledge and perceptions, condom use, and history of STDs. Five common STDs were screened and tested through clinical examination and laboratory testing to serve as biomarkers. After controlling for potential confounders and baseline differences, the VCT intervention group was significantly higher than the control group in HIV/STD related knowledge (p < .0001) and consistent condom use with clients (odds ration [OR] = 2.23; 95% confidence interval [CI] = 1.26-3.96) at 6 months follow-up. In addition, the intervention group had a significantly lower infection rate of STDs than the control group at follow-up (OR = 0.44; 95% CI = 0.24-0.80). This quasi-experimental trial provides evidence that the brief VCT intervention, through appropriate cultural adaptation, can be efficacious in increasing condom use and reducing STD infection rate among FSWs in China.     

Prevalence of HIV Infection and Risk Factors Among Female Sex Workers in a Southeast Province of Vietnam

Female sex workers (FSWs) are at heightened risk of HIV infection. This research aims to determine the prevalence of HIV and relevant risk factors and related behavior among FSWs in Ba Ria – Vung Tau, a southeast province of Vietnam. 420 FSWs were interviewed using a structured questionnaire and biological samples tested for HIV. 2.6 % were found to be HIV positive. HIV infection was significantly higher in FSWs who had low income (≤AUD 200 per month), have had anal sex, have had sex with injecting drug users, and had a low level of HIV/AIDS-related knowledge. Improved employment opportunities and income are important to reduce the pressure for young women to engage in sex work for income purposes, but in public health terms, existing HIV treatment, prevention and intervention programs needs better targeting and improvements to reduce the risk of HIV infection.     

“I wanted evidence that my status had changed,so that is why I tested”: experiences with HIV self-testing among female sex workers in Malawi

ABSTRACT

HIV testing among female sex workers (FSWs) is an established global health priority. HIV self-testing (HIVST) seems to have the potential to address issues of confidentiality, privacy and convenience among this key population. HIVST, however, may result in unintended consequences as its implementation unfolds in a complex sex work context characterised by unequal power relations, stigma and high HIV prevalence. We aimed to explore the experiences of FSWs with HIVST in the context of retesting and antiretroviral usage in Blantyre, Malawi. We used an ethnographic approach to understand meanings and views around HIVST and retesting. We found high levels of retesting, especially among those on antiretroviral, two of which received “false-negative” results. We identified three broad narratives: (1) retesting in response to experiences in the sex work context, (2) retesting driven by the desire to self-monitor HIV-negative status, and (3) retesting in the hope of sero-reversion. The FSWs’ experiences indicate that the implementation of HIVST in this context is complex with potential for unintended harms such as coercive testing. HIVST programmes must include clear and appropriate messaging to reduce retesting while on ART and implement strategies to address FSW concerns and anxieties about the accuracy of their HIV-positive test results.     

Safer sexual behaviors after 12 months of antiretroviral treatment in Mombasa, Kenya: a prospective cohort

Roll-out of antiretroviral treatment (ART) raises concerns about the potential for unprotected sex if sexual activity increases with well-being, resulting in continued HIV spread. Beliefs about reduced risk for HIV transmission with ART may also influence behavior. From September 2003 to November 2004, 234 adults enrolled in a trial assessing the efficacy of modified directly observed therapy in improving adherence to ART. Unsafe sexual behavior (unprotected sex with an HIV-negative or unknown status partner) before starting ART and 12 months thereafter was compared. Participants were a mean 37.2 years (standard deviation [SD] = 7.9 years) and 64% (149/234) were female. Nearly half (107/225) were sexually active in the 12 months prior to ART, the majority (96/107) reporting one sexual partner. Unsafe sex was reported by half of those sexually active in the 12 months before ART (54/107), while after 12 months ART, this reduced to 28% (30/107). Unsafe sex was associated with nondisclosure of HIV status to partner; recent HIV diagnosis; not being married or cohabiting; stigma; depression and body mass index <18.5 kg/m(2). ART beliefs, adherence, and viral suppression were not associated with unsafe sex. After adjusting for gender and stigma, unsafe sex was 0.59 times less likely after 12 months ART than before initiation (95% confidence interval [CI] = 0.37-0.94; p = 0.026). In conclusion, although risky sexual behaviors had decreased, a considerable portion do not practice safe sex. Beliefs about ART's effect on transmission, viral load, and adherence appear not to influence sexual behavior but require long-term surveillance. Positive prevention interventions for those receiving ART must reinforce safer sex practices and partner disclosure.

HIV status and participation in HIV surveillance in the era of antiretroviral treatment: a study of linked population‐based and clinical data in rural South Africa

Objective To examine whether HIV status affects participation in a population‐based longitudinal HIV surveillance in the context of an expanding HIV treatment and care programme in rural South Africa. Method We regressed consent to participate in the HIV surveillance during the most recent fieldworker visit on HIV status (based on previous surveillance participation or enrolment in pre‐antiretroviral treatment (pre‐ART) care or ART in the local HIV treatment and care programme), controlling for sex, age and year of the visit (N = 25 940). We then repeated the regression using the same sample but, in one model, stratifying HIV‐infected persons into three groups (neither enrolled in pre‐ART care nor receiving ART; enrolled in pre‐ART care but not receiving ART; receiving ART) and, in another model, additionally stratifying the group enrolled in pre‐ART and the group receiving ART into those with CD4 count ≤200/μl (i.e. the ART eligibility threshold at the time) vs. those with CD4 count >200/μl. Results HIV‐infected individuals were significantly less likely to consent to participate in the surveillance than HIV‐uninfected individuals [adjusted odds ratio (aOR), 0.74; 95% confidence interval, 0.70–0.79, P < 0.001], controlling for other factors. Persons who were receiving ART were less likely to consent to participate (aOR, 0.75, 0.68–0.84, P < 0.001) than those who had never sought HIV treatment or care (aOR, 0.82, 0.75–0.89, P < 0.001), but more likely to consent than persons enrolled in pre‐ART care (aOR 0.62, 0.56–0.69, P < 0.001). Those with CD4 count ≤200/μl were significantly less likely to consent to participate than those with CD4 count >200/μl in both the group enrolled in pre‐ART and the group receiving ART. Conclusion As HIV test results are not made available to participants in the HIV surveillance, our findings agree with the hypothesis that HIV‐infected persons are less likely than HIV‐uninfected persons to participate in HIV surveillance because they fear the negative consequences of others learning about their HIV infection. Our results further suggest that the increased knowledge of HIV status that accompanies improved ART access can reduce surveillance participation of HIV‐infected persons, but that this effect decreases after ART initiation, in particular in successfully treated patients.     

A Multilevel Analysis of the Impact of Socio-Structural and Environmental Influences on Condom Use Among Female Sex Workers

This study uses multilevel analysis to examine individual, organizational and community levels of influence on condom use among female commercial sex workers (FSW) in the Philippines. A randomized controlled study involving 1,382 female commercial sex workers assigned to three intervention groups consisting of peer education, managerial training, combined peer and managerial intervention and a usual care control group was conducted. The results of the multilevel analysis show that FSWs who work in establishments with condom use rules tend to have a higher level of condom use (β = .70, P < 0.01). Among the different intervention groups, the combined peer and managerial intervention had the largest effect on condom use (β = 1.30, P < 0.01) compared with the usual care group. Using a three-level hierarchical model, we found that 62% of the variation lies within individuals, whereas 24% and 14% of the variation lies between establishments, and communities, respectively. Standard errors were underestimated when clustering of the FSWs in the different establishments and communities were not taken into consideration. The results demonstrate the importance of using multilevel analysis for community-based HIV/AIDS intervention programs to examine individual, establishment and community effects.     

Sex Practices by HIV Awareness and Engagement in the Continuum of Care Among MSM: A National HIV Behavioral Surveillance Analysis in 21 U.S. Cities

Using National HIV Behavioral Surveillance (NHBS) cross-sectional survey and HIV testing data in 21 U.S. metropolitan areas, we identify sex practices among sexually active men who have sex with men (MSM) associated with: (1) awareness of HIV status, and (2) engagement in the HIV care continuum. Data from 2008, 2011, and 2014 were aggregated, yielding a sample of 5079 sexually active MSM living with HIV (MLWH). Participants were classified into HIV status categories: (1) unaware; (2) aware and out of care; (3) aware and in care without antiretroviral therapy (ART); and (4) aware and on ART. Analyses were conducted examining sex practices (e.g. condomless sex, discordant condomless sex, and number of sex partners) by HIV status. Approximately 30, 5, 10 and 55% of the sample was classified as unaware, aware and out of care, aware and in care without ART, and aware and on ART, respectively. Unaware MLWH were more likely to report condomless anal sex with a last male partner of discordant or unknown HIV status (25.9%) than aware MLWH (18.0%, p value < 0.0001). Unaware MLWH were 3 times as likely to report a female sex partner in the prior 12 months as aware MLWH (17.3 and 5.6%, p-value < 0.0001). When examining trends across the continuum of care, reports of any condomless anal sex with a male partner in the past year (ranging from 65.0 to 70.0%), condomless anal sex with a male partner of discordant or unknown HIV status (ranging from 17.7 to 21.3%), and median number of both male and female sex partners were similar. In conclusion, awareness of HIV and engagement in care was not consistently associated with protective sex practices, highlighting the need for continued prevention efforts.     

"It is not that I forget, it's just that I don't want other people to know": barriers to and strategies for adherence to antiretroviral therapy among HIV patients in Northern Vietnam

Antiretroviral therapy (ART) started to become more widely available in Vietnam in 2005. However, up to now, very little is known about factors influencing ART adherence among people living with HIV (PLHIV) in Vietnam. This qualitative study aimed to describe factors influencing ART adherence among PLHIV in a northern province in Vietnam, and to explore possibilities of home delivery of ART. Forty-eight participants (36 men and 12 women), including patients on ART and their relatives, were divided in seven focus group discussions. The topics discussed included: adherence obstacles encountered during ART, methods patients used to enhance adherence, treatment support structures, and attitudes toward home delivery of ART. All interviews were audio-recorded, then transcribed in Vietnamese. Manual manifest and latent content analysis was applied for data analysis in order to elucidate the presence of, meaning of, and relationships between concepts in the text. Stigma was identified as a strong barrier to ART adherence, as patients feared that taking medications in the presence of other persons would lead to suspicion or inadvertent disclosure of their HIV status. In addition to desires for non-disclosure influencing PLHIV's adherence, it also shaped their attitudes toward opting for more confidential ways of receiving ART support and care. Home delivery of ART medications was seen as undesirable by participants, who feared that it might increase social stigmatization. Participants wished for more community-based support, preferably from PLHIV who had received sufficient training. Based on the results of this study, an intervention strategy using PLHIV as community-based adherence supporters is currently being evaluated in a randomized controlled trial intervention, including 640 patients in Quang Ninh, Vietnam.     

Effects of Micro-Enterprise Services on HIV Risk Behaviour Among Female Sex Workers in Kenya’s Urban Slums

This study assessed individual-level effects of adding micro-enterprise services to a peer-mediated HIV/AIDS intervention among 227 female sex workers (FSWs) in Kenya. Survey data were collected in May–July 2003 and July–August 2005. Two-thirds of participants had operational businesses by end-line survey. Nearly half reported to have stopped sex work. Self-reported weekly mean number of all sexual partners changed from 3.26 (SD 2.45) at baseline to 1.84 (SD 2.15) at end-line survey (P < 0.001). Weekly mean number of casual partners did not change significantly. Weekly mean number of regular partners changed from 1.96 (SD 1.86) to 0.73 (SD 0.98) over the follow-up period (P < 0.001). Consistent condom use with regular partners increased by 18.5% and remained above 90% with casual partners. Micro-enterprise services may empower FSWs by giving them an alternative livelihood when they wish to exit or reduce reliance on sex work. Determinants of successful business operation by FSWs deserve further research.     

Condom use, intervention service utilization and HIV knowledge among female sex workers in China: results of three consecutive cross-sectional surveys in Shandong Province with historically low HIV prevalence

Heterosexual transmission of HIV through contact with female sex workers (FSWs) is a growing concern for the HIV/AIDS epidemic in China. Using consecutive cross-sectional surveys, we examined the prevalence of HIV and sexually transmitted infections (STIs), risk behaviours, HIV knowledge and the utilization of intervention services among FSWs in Shandong Province. Of 3460 participants, half reported ever having STI-related symptoms, 57.8% had ≥7 clients in the last week, half reported inconsistent use of condoms with clients and 11.2% reported ever using illicit drugs. Consistent use of condoms with clients was associated with higher education, being 20-24 years of age, being recruited from hotels, having ever received free condoms and was inversely associated with STI-related symptoms. HIV-related knowledge was associated with higher education, ever testing for HIV and inversely associated with self-reported STI-related symptoms. The low rates of condom use, high number and frequent turnover of clients, high prevalence of self-reported STIs and drug use highlight the urgency for more effective intervention in these FSWs.     

A Randomized Controlled Trial of an HIV Prevention Intervention for Street-Based Female Sex Workers in Yerevan,Armenia: Preliminary Evidence of Efficacy

This study evaluated the efficacy of an HIV intervention among female sex workers (FSWs) randomized to an intervention or wait-list control. FSWs (N = 120) completed baseline, 3- and 6-month assessments. A health educator implemented 2-hour intervention emphasized gender-empowerment, self-efficacy to persuade clients to use condoms, condom application skills, and eroticizing safer sex. Over the 6-month follow-up, FSWs in the intervention reported more consistent condom use with clients (P = .004) and were more likely to apply condoms on clients (P = .0001). Intervention effects were observed for other psychosocial mediators of safer sex. Brief, gender and culturally congruent interventions can enhance HIV-preventive behaviors among FSWs.     

HIV Serostatus Disclosure and Engagement in Medical Care Among Predominantly Low Income but Insured African American Adults with HIV

More than half of persons living with HIV (PLWH) do not enter into or remain in continuous HIV medical care. Disclosure of HIV serostatus to social contacts may play an important role in successful engagement of PLWH with medical care. The effect of disclosure on medical care engagement was examined in a sample of African American PLWH (n = 262) recruited from community-based organizations as part of a peer community health worker initiative. At baseline assessment, many of the PLWH (46 %) reported they had not disclosed their serostatus to others. Engagement in medical care was assessed 45 and 90 days after enrollment. Participants who disclosed their HIV status were subsequently more likely to engage in HIV medical care (78 %) than persons who did not disclose their status (66 %), an effect that was confirmed in multiple logistic regression. The findings highlight disclosure as an important predictor of engagement in HIV medical care for PLWH.     

Is the bed capture enzyme immunoassay useful for surveillance in concentrated epidemics? The case of female sex workers in Indonesia

Although the BED capture enzyme immunoassay (BED-CEIA) tends to over-estimate HIV incidence in general population epidemics, its limitations may be less relevant to some sub-populations in concentrated epidemics. This study assesses the plausibility of BED-CEIA estimates for female sex workers (FSWs) in Indonesia. Data were derived from a cross-sectional anonymous linked behavioral and biological surveillance survey. Independent samples of 2,917 direct and indirect FSWs, were gathered from seven and five cities, respectively, via three-stage time-location sampling. Participants provided behavioral information, venous blood and vaginal swabs. Specimens testing positive for HIV were subjected to BED-CEIA to identify recent infections. The median duration of sex work was 12 months. The estimated HIV prevalence was 8.2% and the incidence was 4.1 per 100 person years, slightly lower than an Asian Epidemic Model (AEM) estimate. HIV incidence was higher among: direct FSWs (p<0.001), those reporting genital ulcers in the past year (p<0.001), those with active syphilis (p=0.017), and those not receiving periodic presumptive treatment for STIs during the previous 6 months (p=0.045). Low general population HIV prevalence, short durations of sex work and low ART coverage of those eligible for treatment make it unlikely that HIV incidence estimates for FSWs in Indonesia are distorted by long-standing infections and viral suppression. External consistency with model-based estimates and internal consistency in regard to known risk factors for HIV infection add to the plausibility of the estimates. Pending advances in methods for estimating HIV incidence, it may be premature to summarily dismiss the BED-CEIA in concentrated HIV epidemics.     

Is co-location of services with HIV care associated with improved HIV care outcomes? A systematic review

ABSTRACT

This systematic review identifies models of service co-location, a structural intervention strategy to remove barriers to HIV care and services, and examines their associations with HIV care outcomes. A cumulative database (e.g., MEDLINE, EMBASE) of HIV, AIDS, and STI literature was systematically searched and manual searches were conducted to identify relevant studies. Thirty-six studies were classified into six models of co-location: HIV care co-located with multiple ancillary services, tuberculosis (TB) care, non-HIV specific primary care, drug abuse treatment, prevention of mother to child transmission programs (PMTCT), and mental health care. More evidence of a positive association was seen for linkage to care and antiretroviral therapy (ART) uptake than for retention and viral suppression. Models of co-location that addressed HIV and non-HIV medical care issues (i.e., co-location with non-HIV specific primary care, PMTCT, and TB) had more positive associations, particularly for linkage to care and ART uptake, than other co-location models. While some findings are encouraging, more research with rigorous study designs is needed to strengthen the evaluation of, and evidence for, service co-location.     

Mobilizing individual social capital resources for HIV care support: results of a pilot intervention in St. Petersburg,Russia

ABSTRACT

Half of HIV-positive persons in Russia are on antiretroviral therapy (ART), and only 27% are virally suppressed. A feasibility pilot intervention to mobilize social capital resources for HIV care support was conducted in St. Petersburg. Out-of-care or ART-nonadherent HIV-positive persons (n?=?24) attended a five-session intervention to increase access social capital resources (i.e., family, friends, or providers) to mobilize supports for entering care, initiating care, and adhering to ART. HIV care indicators were assessed at baseline, an immediate followup (FU-1), and 6-month followup (FU-2) points. At FU-1, participants more frequently discussed their care experiences with others, verifying the intervention’s mechanism of action. Participants increased in scales of medication taking adherence (p?=?0.002, FU-1; p?=?0.011, FU-2), self-efficacy (p?=?0.042; FU-1), and outcome expectancies (p?=?0.016, FU-2). Among persons not on ART, HIV Medication Readiness scale scores increased at FU-1 (p?=?0.032) but became attenuated at FU-2. Participants tended to more frequently keep care appointments (79%, baseline to 90%, FU-1, p?=?0.077); to have undetectable viral load (54%, baseline to 74%, FU-2; p?=?0.063); and to have fewer past-month days with delayed or incomplete medication doses (7.8, baseline to 4.2, FU-1; p?=?0.084). This novel social capital intervention is promising for improving HIV care-related outcomes and warrants a full-scale evaluation.
