Substance use is associated with condomless anal intercourse among men who have sex with men in India: a partner-level analysis

BackgroundMen who have sex with men (MSM) bear a disproportionately high burden of new HIV infections while lagging behind other populations with respect to engagement across the HIV care continuum. General risk factors for condomless anal intercourse (CAI) among MSM are well studied but there is a paucity of partner-level data, where emerging evidence suggests that much of the variation in condom use occurs.MethodsMSM were recruited across 10 cities in India using respondent-driven sampling (RDS) from 2016–17. Among the individuals who reported sexual intercourse in the prior 6 months, condom use and partner characteristics of the last 4 partners were captured. Correlates of CAI at the individual and partner level were determined using Poisson regression models using generalized estimating equations and incorporating RDS-II weights, which weights estimates for the participant’s network size.ResultsAmong the 8,086 individuals, 21,723 sexual partnerships were analyzed. The prevalence of CAI was 46.9% and most partners were casual or one-time (70.7%) with partner HIV status reported as unknown in 42.6% of the sexual encounters. In multivariable analyses, partner-level characteristics associated with higher likelihood of CAI included unknown partner HIV status (aPR vs. known HIV negative partner: 1.34; 95% confidence interval (CI): 1.27–1.43) and use of alcohol/ drugs prior to intercourse either sometimes (aPR 1.42; 95% CI: 1.33–1.51) or always (aPR 1.31; 95% CI: 1.23–1.41). At an individual level, any HIV treatment literacy was associated with a lower likelihood of CAI (aPR 0.80; 95% CI: 0.74–0.86).ConclusionsTo reduce HIV transmission among this population of MSM across India, combination interventions are likely needed. Interventions targeting substance use and education as well as initiatives to increase self-testing are urgently needed among MSM in India and have the potential to reduce HIV transmission in this high-risk population.Trial registrationClinicalTrials.gov Identifier: NCT01686750.

Prevalence of condomless anal intercourse and associated risk factors among men who have sex with men in Bamako, Mali.

Men who have sex with men (MSM) are disparately impacted by HIV in sub-Saharan Africa and condomless anal intercourse (CAI) is a major driver of HIV transmission. The objective of the current study was to identify factors associated with CAI among MSM in Bamako, Mali, among whom HIV prevalence was 13.7%. A bio-behavioral survey was conducted between October 2014 and February 2015 using respondent-driven sampling to recruit 552 adult MSM. Weighted statistical analyses were conducted to determine the prevalence of CAI with one's most recent male partner and survey logistic procedures were used to identify associated factors. The prevalence of CAI with one's most recent male partner was 40.7%. Associated factors included: inability to get a condom when needed (aOR = 5.8, 95%CI: 2.7-12.3) and believing CAI is acceptable under some circumstances (aOR = 8.4, 95%CI: 4.4-16.2). Programs addressing HIV among MSM in Mali should aim to increase access to condoms and education about HIV prevention through consistent condom use during anal intercourse.

Impact of Minority Stress and Poor Mental Health on Sexual Risk Behaviors among Transgender Women Sex Workers in Shenyang, China.

This study examined the associations between minority stressors, poor mental health, and sexual risk behaviors, and whether there were interactive effects of minority stress and mental health factors in their associations with sexual risk behaviors in a sample of Chinese transgender women sex workers (TGSW). A cross-sectional study was conducted in 204 TGSW in Shenyang, China (mean age 33.4years and 18.1% self-reported as HIV positive). We found a high prevalence of condomless anal intercourse (CAI) with male clients (27.9%) and CAI with male regular partners (49.5%) in the past three months among TGSW. Multivariate logistic regression analysis showed that discrimination, victimization, and life dissatisfaction were significantly associated with higher odds of CAI with male clients (AOR range: 1.05-1.42, all p < 0.05). Likewise, CAI with male regular partners was more frequently reported by participants who experienced higher levels of victimization, rejection, and anxiety (AOR range: 1.37-2.88, all p < 0.05). No significant interaction effects of gender minority stress and mental health on sexual behaviors were observed. Interventions addressing the multiple psychosocial risks are warranted to prevent behavioral risks of TGSW.

Parent/Caregiver Responses to Gender Identity Associated With HIV-Related Sexual Risk Behavior Among Young Trans Women in San Francisco

PurposeYoung trans women (YTW) carry a disproportionate burden of HIV. The developmental context of HIV risk for YTW is underexamined. The aim of this analysis was to examine whether parent/caregiver responses to gender identity were associated with engagement in HIV-related sexual risk behavior for YTW and whether these associations varied by racial/ethnic identity or age. MethodsBaseline data from the SHINE study (n = 300) at San Francisco Department of Public Health (2012–2014) were analyzed. Multivariable Poisson binomial regression models characterized relationships between parent/caregiver responses to gender identity and HIV-related sexual risk behaviors, adjusting for select participant demographics. Statistically significant interactions (by race/ethnicity or age) were plotted using marginal predicted probabilities of sexual risk behaviors. ResultsThirty-seven percent of YTW engaged in any condomless anal intercourse; 12% reported income from sex work in the last month. Ever moving away from family and friends because of gender identity was associated with condomless anal intercourse (adjusted prevalence ratio [PR] = 1.44, 95% confidence interval [CI] = 1.08–1.92, p = .01) and sex work (PR = 2.07, 95% CI = 1.14–3.75, p=.02). Ever receiving poor treatment from parents/caregivers because of gender identity was associated with sex work (PR = 3.47, 95% CI = 1.52–7.95, p < .01). Greater parent/caregiver acceptance of gender identity was associated with lower adjusted prevalence of condomless anal intercourse for Hispanic/Latinx YTW. ConclusionsNegative parent/caregiver exposures related to YTW's gender identities were associated with increased HIV-related sexual risk behaviors, whereas parent/caregiver acceptance of gender identity was protective against condomless anal intercourse for Hispanic/Latinx YTW. There is a need for additional studies that inform interventions for YTW focusing on parent/caregiver relationships to prevent HIV-related risk behavior.

Extragenital chlamydia infection among active-duty women in the United States Navy

BackgroundPharyngeal and anorectal reservoirs of gonorrhea (GC) and chlamydia (CT) are increasingly recognized among heterosexual women. While a number of studies performed at sexually transmitted disease (STD) clinics have found a high prevalence of extragenital GC/CT infection, such screening is typically not offered during routine primary care visits for women. We sought to define the prevalence of and factors associated with extragenital GC/CT among women in the U.S. Navy.MethodsWe recruited servicewomen stationed in San Diego, California, between the ages of 18 and 25 who presented for an annual physical exam between January and September, 2017. Nucleic acid amplification testing was performed on swabs collected at endocervical, oropharyngeal and anorectal sites to assess the presence of GC/CT. An anonymous behavioral questionnaire was also administered to characterize sexual risk. Descriptive statistics were used to compare women with and without a prior history of any sexually transmitted infection (STI) (self-report) along with a current GC/CT diagnosis. This study was approved by the Institutional Review Board of the Uniformed Services University of Health Sciences.ResultsOf the 75 patients who were approached, 60 subjects were enrolled in the study, including white 20 (33.3%), black/African American 18 (31.0%), Hispanic/Latina 13 (21.7%) and Asian/Pacific Islander 9 (15.5%) women. Among all the women, six (10.0%) were diagnosed with CT infection, all via endocervical exam. Of these, five (8.3%) had concurrent anorectal infection, including two cases (3.3%) accompanied by pharyngeal infection. Of the subjects, 15 (25.0%) reported anal intercourse in their most recent sexual encounter, most of which was condomless (13/15, 86.7%). A high number of women who reported sex with a casual male partner (19/45, 42.2%) reported rarely or never using condoms; last, 41.7% consuming at least 3 drinks on a typical drinking day, and one-third of the reported drinking more than once per week.ConclusionsWe found a high prevalence of anorectal CT infection, although no infections were detected without concurrent endocervical involvement. Nonetheless, the high prevalence of condomless anal intercourse reported by participants argues for further study and ongoing consideration of extragenital screening among high-risk patients. Behavioral interventions are also warranted given the high prevalence of sexual and related risk factors.

Prevalence of condomless anal intercourse and recent HIV testing and their associated factors among men who have sex with men in Hangzhou, China: A respondent-driven sampling survey.

Men who have sex with men (MSM) are a large high-risk population for HIV infection in recent years in China. A cross-sectional survey was conducted in Hangzhou, China, to determine rates of condomless anal intercourse (CAI), recent HIV testing (in the recent year) and associated factors using respondent-driven sampling. Questionnaires using face-to-face interviews were employed to collect data on sexual risk behaviors and HIV testing. Five hundred eleven MSM were recruited, of which 459 (89.8%) had anal intercourse in the past 6 months. Of these 459 participants, 457 (99.6%) answered whether they had taken an HIV test in the recent year, so only their data were analyzed. Weighted data were analyzed using bivariate and multivariate logistic regression analysis. The CAI rate with male partners in the past 6 months was 43.7% (95% confidence interval [CI], 34.0–51.5%), while the rate of condomless vaginal intercourse (CVI) was 21.6% (95% CI, 15.6–32.3%). The prevalence of recent HIV testing was 56.8% (95% CI, 48.7–66.5%), while the prevalence of HIV and syphilis were 8.8% and 6.5%, respectively. Multivariate analysis indicated that CAI was associated with earlier homosexual debut, suicidal inclinations, childhood sexual abuse, HIV testing in the recent year, and lower estimate of HIV prevalence. Recent HIV testing was associated with homosexual debut age, engaging in CAI with male partners in the past 6 months, having oral sex in the past 6 months, self-perceived higher likelihood of HIV infection, knowing about antiretroviral therapy for HIV/AIDS, receiving AIDS/sexually transmitted infection (STI) interventions in the past year, and syphilis infection. Given high prevalence of HIV and syphilis, high levels of CAI and CVI, and low HIV testing rate, the results indicated high risk of HIV infection and transmission among MSM. HIV prevention interventions should target MSM with early homosexual debut and psychosocial health problems, while HIV/AIDS education among MSM should focus on increasing knowledge of HIV risk, estimated HIV prevalence and antiretroviral therapy, and improving risk perception of HIV acquisition.

Prevalence and associated factors of condomless receptive anal intercourse with male clients among transgender women sex workers in Shenyang, China.

IntroductionGlobally, transgender women sex workers have a high prevalence of HIV and condomless receptive anal intercourse with male clients (CRAIMC). We investigated the prevalence of CRAIMC and factors associated with CRAIMC among transgender women sex workers in China.MethodsIn 2014, we anonymously interviewed 220 transgender women sex workers face to face in Shenyang, China. Those who self-reported as HIV negative or as having unknown HIV serostatus were invited to take up free, anonymous HIV rapid testing (n=183); 90 did so. Using CRAIMC in the last month as the dependent variable, three types of associated factors were investigated, in addition to background factors: feminizing medical interventions, sex work and perceptions related to condom use. Univariate and multiple logistic regression models were fitted.ResultsOf the participants, 16.8% self-reported as HIV positive and 9.1% were detected to be HIV positive through free HIV testing; 26.8% had had CRAIMC in the last month, 45.5% had performed sex work in other Chinese cities (last year), and 23.2% had had condomless anal intercourse with men who were non-clients. In the adjusted analysis, significant factors associated with CRAIMC (last month) included the following: 1) any feminizing medical intervention performed (adjusted odds ratio, AOR: 2.22); 2) sex-work-related factors, including recruitment of male clients most often at hotels (AOR: 5.02) and charge per episode of transactional sex (201 to 400 RMB, AOR: 0.27; reference group: ≤100 RMB); and 3) perceptions related to condom use, including perceived transgender identity's impact on condomless sex such as wearing feminine attire, concern about exposing their status as a transgender woman to male clients (AOR: 1.20) and perceived self-efficacy of consistent condom use with male clients (AOR: 0.56). Perceived self-efficacy of consistent condom use with male clients fully mediated the association between perceived transgender identity's impact on condomless sex and CRAIMC.ConclusionsHIV prevalence among transgender women sex workers was high but probably underestimated. The high prevalence of condomless anal intercourse with male non-clients and high mobility in sex work among this population in China are causes for concern. Risk factors for CRAIMC were multidimensional and should be considered when designing interventions targeting transgender women sex workers. Such interventions are urgently needed.

Condomless Anal Intercourse Among Males and Females at High Risk for Heterosexual HIV Infection.

Understanding and addressing heterosexual HIV transmission requires attention to the range and context of heterosexual sexual behaviors. We sought to determine population-based prevalence of condomless anal intercourse (CAI) among individuals at increased heterosexual HIV risk in Baltimore and to identify demographic, behavioral, and health-related correlates. Data were from a cross-sectional study of 185 males and 198 females at increased heterosexual risk for HIV recruited using respondent-driven sampling as part of Centers for Disease Control and Prevention's National HIV Behavioral Surveillance Project in Baltimore, August-December 2010. Bivariate and multivariate logistic regression examined factors associated with heterosexual CAI. The sample was majority African American, with a mean age of 38 years among men and 34 years among women. Forty-two percent of men (95% confidence interval, 30.9%-52.0%) and 38% of women (95% confidence interval, 29.4%-47.2%) reported any CAI in the past year, with variance by partner type and sex. Among men, CAI was significantly associated with homelessness, casual and exchange partners, same-sex partner in past year, and substance use. Among women, CAI was significantly associated with lower education, casual and exchange partners, same-sex partner in past year, multiple partners, and substance use. In adjusted sex-specific models, males and females with increasing numbers of partners were more likely to engage in CAI. It is important to recognize the efficiency of transmission of HIV and other sexually transmitted infections through CAI. There is a need to broaden heterosexual sexual health promotion and HIV/sexually transmitted infection prevention to adequately and appropriately address risks and prevention strategies for anal intercourse.
