Prevalence and correlates of transactional sex among women of low socioeconomic status in Portland, OR.

BACKGROUND: Women who report transactional sex are at increased risk for HIV and other sexually transmitted infections (STIs). However, in the United States, social, behavioral, and trauma-related vulnerabilities associated with transactional sex are understudied and data on access to biomedical HIV prevention among women who report transactional sex are limited. METHODS: In 2016, we conducted a population-based, cross-sectional survey of women of low socioeconomic status recruited via respondent-driven sampling in Portland, Oregon. We calculated the prevalence and, assessed the correlates of, transactional sex using generalized linear models accounting for sampling design. We also compared health outcomes, HIV screening, and knowledge and uptake of HIV pre-exposure prophylaxis (PrEP) between women who did and did not report transactional sex. RESULTS: Of 334 women, 13.6% reported transactional sex (95% confidence interval [CI]: 6.8, 20.5%). Women who reported transactional sex were older, more likely to identify as black, to identify as lesbian or bisexual, to experience childhood trauma and recent sexual violence, and to have been homeless. Six percent (95% CI: 1.8, 10.5%) of women with no adverse childhood experiences (ACEs) reported transactional sex compared to 23.8% (95% CI: 13.0, 34.6%) of women who reported eleven ACEs (P <  0.001). Transactional sex was strongly associated with combination methamphetamine and opiate use as well as condomless sex. Women who reported transactional sex were more likely to report being diagnosed with a bacterial STI and hepatitis C; however, HIV screening and pre-exposure prophylaxis knowledge and use were low. CONCLUSIONS: In a sample of women of low socioeconomic status in Portland, Oregon, transactional sex was characterized by marginalized identities, homelessness, childhood trauma, sexual violence, substance use, and sexual vulnerability to HIV/STI. Multi-level interventions that address these social, behavioral, and trauma-related factors and increase access to biomedical HIV prevention are critical to the sexual health of women who engage in transactional sex.

Pre-exposure Prophylaxis Awareness and Use Among Cisgender Men Who Have Sex With Men and Use Methamphetamine in 3 Western US Cities.

BACKGROUND: In the United States, cisgender men who have sex with men (MSM) who use methamphetamine are at substantial risk for HIV and can benefit from pre-exposure prophylaxis (PrEP). METHODS: We used data from the National HIV Behavioral Surveillance 2017 survey from Seattle, WA; Portland, OR; and Denver, CO, to estimate PrEP awareness and use in the past 12 months among MSM who use methamphetamine. We then compared these estimates with participants who do not use methamphetamine but meet other criteria for PrEP use (i.e., condomless anal sex or a bacterial sexually transmitted infection). We explored reasons for not using PrEP and challenges using PrEP. RESULTS: Of the 1602 MSM who participated in the 2017 National HIV Behavioral Surveillance survey in Seattle, WA; Portland, OR; and Denver, CO, 881 met the inclusion criteria for this study, of whom 88 (10%) reported methamphetamine use in the past 12 months. Most (95%) participants had heard of PrEP, and 35% had used it in the past 12 months. Pre-exposure prophylaxis awareness was lower among MSM who used methamphetamine (P = 0.01), but use was not different (P = 0.26). Among those who had not used PrEP, the most common reason for not using it was not thinking one's HIV risk was high enough (51%). Men who have sex with men who used methamphetamine were more likely to report that they were not sure PrEP would prevent them from getting HIV (38% vs. 19%, P = 0.002). CONCLUSIONS: These results highlight the need for continued efforts to educate and promote PrEP uptake among MSM, particularly those who use methamphetamine.

Self-Reported Screening for Rectal Sexually Transmitted Infections Among Men Who Have Sex With Men.

BACKGROUND: Rectal gonorrhea and chlamydia are common and predict human immunodeficiency virus (HIV) acquisition among men who have sex with men (MSM); however, screening for rectal sexually transmitted infections (STIs) is not routine. METHODS: In 2017, we recruited sexually active MSM in the Portland, Oregon metropolitan area through venue-based sampling. Our outcome of interest was self-reported rectal STI screening in the prior 12 months among those who had a health care visit in the same time period. Stratified by HIV status and preexposure prophylaxis (PrEP) use, we assessed the prevalence and predictors of screening. RESULTS: Of 403 participants, 162 (40.2%) reported rectal STI screening. Sixty (25.7%) of 233 HIV-negative men who did not report PrEP use in the prior 12 months; 61 (69.3%) of the 88 HIV-negative men who reported PrEP use in the prior 12 months; and, 41 (59.4%) of 69 men living with HIV-reported screening, respectively. Among HIV-negative men who did not report PrEP use in the prior 12 months, having a health care provider who offered HIV testing (adjusted prevalence ratio [aPR], 2.21; 95% confidence interval [CI], 1.38-3.52) and condomless anal sex with casual partners in the prior 12 months (aPR, 1.63; 95% CI, 1.01-2.65) were independently associated with rectal STI screening. The HIV-negative men on PrEP who had a syphilis diagnosis in the prior 12 months were more likely to be screened than those without syphilis (aPR, 1.33; 95% CI, 1.11-1.59). Men living with HIV who reported having a provider who always or often initiates conversations about sex were more likely to report screening compared with men who did not have such a provider (aPR, 1.46; 95% CI, 1.06-2.03). CONCLUSIONS: Rectal STI screening is not universal in a venue-based sample of sexually active MSM. Implementing innovative, acceptable, and accessible screening practices, enhancing health literacy around STI screening and improving provider comfort with talking about sex are paramount to increasing rectal STI screening.
