Pre-exposure prophylaxis (PrEP), an antiretroviral medication to prevent HIV, is becoming more widely available in the United States since the Federal Drug Administration approved it in 2012. However, PrEP use among men who have sex with men (MSM) is still limited and many MSM who are willing to take PrEP are not on PrEP. We performed a systematic review to identify factors associated with willingness to use PrEP among MSM who are not on PrEP. The majority of the 23 relevant studies had low risk of bias and used a cross-sectional design. Willingness was associated with being Hispanic/Latino (odds ratio [OR] = 1.68, 95% confidence interval [CI] [1.01-2.78]), Black (OR = 1.41, 95% CI [1.02-1.95]), younger (OR = 1.08, 95% CI [1.02-1.15]), having no college degree (OR = 1.37, 95% CI [1.12-1.59]), or low income (OR = 1.21, 95% CI [1.12-1.32]). A higher proportion of MSM who had recent condomless anal sex (OR = 1.85, 95% CI [1.49-2.29]) were diagnosed with sexually transmitted infection (OR = 1.60, 95% CI [1.27-2.01]), or MSM who had multiple sex partners (OR = 1.58, 95% CI [1.07-2.32]) were more willing to use PrEP compared with their respective counterparts. Findings suggest that MSM with racial/ethnic minority status, low-socioeconomic status, younger age, and engagement in HIV risk behaviors are willing to take PrEP but may lack access. Study limitations include the inability to conduct meta-analyses on certain predictor variables due to a small number of studies. This review identified MSM subpopulations who may benefit from interventions increasing PrEP access.

HIV (human immunodeficiency virus) preexposure prophylaxis (PrEP) is an effective biomedical HIV prevention tool. Increasing PrEP use among populations disproportionately affected by HIV is one of the key efforts in the United States’ Ending the HIV Epidemic (EHE) initiative and the HIV National Strategic Plan for the United States. Given that PrEP is available only through prescription, it is important to explore structural, organizational, or environmental factors that could facilitate or impede health care provider’s PrEP prescribing behavior. The purpose of this systematic review (PROSPERO [CRD: 42019138889]) is to identify qualitative studies that addressed this topic and conduct meta-synthesis using the thematic synthesis method to identify major themes on the characteristics of clinic infrastructure or clinic models that providers consider as facilitators of PrEP prescribing in the United States. Eighteen citations representing 15 studies were included in this review. Five overarching themes were identified: (1) routinized HIV risk assessment; (2) interdisciplinary/coordinated PrEP teams or services; (3) clinic capacity to provide essential PrEP-related services; (4) low out-of-pocket patient costs; and (5) access to the priority populations. Some of these themes are consistent with the recommendations of CDC’s PrEP clinical guidelines and the EHE initiative. More recent studies that include perspectives of diverse providers, timely analysis of these studies, and implementation research to assess strategies to address the current practice gaps are needed to further promote PrEP prescribing among providers in the United States.

We (1) estimated the prevalence of not getting patient navigation despite feeling a need for the service (unmet subjective need) or despite having unsuppressed viral load (unmet objective need) among people with HIV (PWH), (2) determined reasons why PWH did not use the service, and (3) determined factors associated with unmet need for patient navigation. We used combined data from the 2015 to 2017 cycles of the Medical Monitoring Project, an HIV surveillance system designed to produce nationally representative estimates of the characteristics of adults with diagnosed HIV infection in the United States. Six percent reported unmet subjective need and 28% had unmet objective need for patient navigation. When needs were combined, more than a third had unmet need for the service. Among PWH with unmet subjective need for patient navigation, 77% reported lack of knowledge about patient navigation as a reason for nonuse. Younger age, female gender, racial/ethnic minority status, limited health literacy, homelessness, incarceration history, lack of health insurance/coverage, noninjection drug use, depression, and recent HIV diagnosis were associated with unmet subjective or objective need for patient navigation. One in three PWH did not use patient navigation despite needing the service. Lack of knowledge about patient navigation was a barrier to use, calling for increased availability, and promotion of such services. PWH with social and economic vulnerabilities were less likely to get patient navigation when needed. It is important to address the question of how to make this service available to everyone who needs it.

We sought to identify and compare correlates of condomless receptive anal intercourse with HIV-positive or unknown status partners (CRAI) for younger (< 25 years) and older (≥ 25 years) Hispanic/Latino, black/African-American, and white men who have sex with men (MSM). Baseline data from the Evaluation of Rapid HIV Self-Testing among MSM Project (eSTAMP), a randomized controlled trial with MSM (n = 2665, analytical sample size = 2421), were used. Potential correlates included participants’ sociodemographic characteristics and HIV status as well as the characteristics of participants’ partners. Younger Hispanic/Latino and black men were most likely to report having older sex partners (≥ 50% of partners being at least 5 years older), and having older partners was a significant correlate of CRAI among younger Hispanic/Latino and white men. Regardless of race/ethnicity, not knowing one’s HIV status was a significant correlate of CRAI among younger men, whereas having a black sex partner was a significant correlate among older men. HIV prevention initiatives could address these and other correlates specific to race/ethnicity groups to target their prevention resources and messaging.

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.

Objective: Guidelines recommend risk-reduction counseling by HIV providers to all HIV-infected persons. Among HIV-infected adults receiving medical care in the United States, we estimated prevalence of exposure to three types of HIV/sexually transmitted disease (STD) risk-reduction interventions and described the characteristics of persons who received these interventions. Design: Data were from the Medical Monitoring Project (MMP), a supplemental HIV surveillance system designed to produce nationally representative estimates of behavioral and clinical characteristics of HIV-infected adults receiving medical care in the United States. Methods: Descriptive analyses were conducted to estimate the exposure to each type of HIV/STD risk-reduction intervention. Bivariate and multivariable analyses were conducted to assess associations between the selected correlates with each exposure variable. Results: About 44% of participants reported a one-on-one conversation with a healthcare provider about HIV/STD prevention, 30% with a prevention program worker, 16% reported participation in a small group risk-reduction intervention, and 52% reported receiving at least one of the three interventions in the past 12 months. Minority race/ethnicity, low income, and risky sexual behavior consistently predicted greater intervention exposure. However, 39% of persons who reported risky sex did not receive any HIV/STD risk-reduction interventions. Conclusions: HIV-infected persons in care with fewer resources or those who engaged in risk behaviors were more likely to receive HIV/STD risk-reduction interventions. However, less than half of HIV-infected persons in care received HIV/STD prevention counseling from their provider, an intervention that has been shown to be effective and is supported by guidelines.

Little research has been conducted to examine whether correlates of sexual risk vary by nativity among Latino men who have sex with men (MSM). We used cross sectional data collected from 870 Latino MSM recruited with respondent-driven sampling techniques. For each sub-sample (US-born and foreign-born), we assessed the association between each of the potential correlates (substance use, acculturation, social support, and social discrimination) and sexual risk behavior. Illicit drug use was associated with increased odds of sexual risk behavior in both US-born (OR = 2.17, 95 % CI 1.17–4.03) and foreign-born (OR = 1.86, 1.14–3.05) subgroups. Multivariate correlates specific to foreign-born men included binge drinking (OR = 1.91, 1.17–3.14), 15 years or longer spent in the US (OR = 1.79, 1.06–3.03) and exposure to social discrimination (OR = 2.02, 1.03–3.99). Given the diversity of Latino MSM, information from research that identifies both common and different HIV risk factors across subgroups of Latino MSM may help better tailor HIV prevention programs.

Using cross-sectional data collected from 1081 Latino men who have sex with men (MSM) recruited with respondent-driven sampling (RDS) techniques from Los Angeles and New York, we examined the extent to which Latino MSM reported exposure to social discrimination (i.e., experienced both homophobia and racism, homophobia only, racism only, or neither homophobia nor racism). More than 40% of respondents experienced both homophobia and racism in the past 12 months. Los Angeles participants, those with lower income, and those who reported being HIV-positive were more likely to report experiencing both types of social discrimination. Adjusting for potential confounders, men exposed to both homophobia and racism were more likely than men exposed to neither form of discrimination to report unprotected receptive anal intercourse with a casual sex partner (AOR = 1.92, 95% CI, 1.18–3.24) and binge drinking (AOR = 1.42, 95% CI, 1.02–1.98). Our findings suggest the presence of a syndemic of adverse social experiences and call for more intervention research to address both homophobia and racism experienced among Latino MSM in the United States.
