Trends in Sexual Risk Behaviors Among Hispanic/Latino Men Who Have Sex with Men — 19 Urban Areas, 2011–2017

Correct and consistent condom use and human immunodeficiency virus (HIV) preexposure prophylaxis (PrEP) are protective against sexual transmission of HIV (1,2). The incidence of HIV infection among Hispanic/Latino men who have sex with men (MSM) in the United States is increasing (3). HIV risk among Hispanic/Latino MSM differs based on their place of birth and years of U.S. residence (4). Data from CDC's National HIV Behavioral Surveillance (NHBS)* for 2011-2017 were analyzed to assess changes in sexual risk behaviors among Hispanic/Latino MSM by place of birth and years of U.S. residence. Overall, condomless anal sex during the previous 12 months increased from 63% in 2011 to 74% in 2017, and PrEP use during the previous 12 months increased from 3% in 2014 to 24% in 2017. Regardless of place of birth, nearly 75% of Hispanic/Latino MSM reported condomless anal sex during 2017. However, because of PrEP use, <60% of non-U.S.-born Hispanic/Latino MSM and <50% of U.S.-born Hispanic/Latino MSM reported unprotected anal sex (condomless anal sex and no PrEP use) during 2017. Results indicate that PrEP can be a vital tool for reducing HIV transmission among Hispanic/Latino MSM, especially those who have condomless anal sex. Interventions to prevent HIV acquisition, including increasing PrEP uptake, could address cultural and linguistic needs of Hispanic/Latino MSM, as well as other barriers to prevention of HIV infection typically faced by all MSM.

In 2011, 2014, and 2017, NHBS conducted behavioral surveys and HIV testing among MSM by using venue-based sampling. The analysis was limited to eligible participants † from 19 † Eligible participants included men who were born male and self-identified as male, reported having ever had oral or anal sex with another man, resided in the interview area, were aged ≥18 years, could complete a standardized interview in English or Spanish, and provided informed consent to participate. Surveys were administered in person by trained interviewers. All participants were offered anonymous HIV testing and incentives for the interview and HIV test. for age and region were used to estimate adjusted prevalence ratios (aPRs) and 95% confidence intervals (CIs). Differences in the trends by place of birth and years of U.S. residence were determined using score tests to obtain interaction p-values that assessed the interaction between 1) year and 2) place of birth and length of U.S. residence. Because PrEP was approved for use in 2012,** comparisons of unprotected anal sex during the previous 12 months were made only for data collected in 2014 and in 2017. Analyses were conducted using SAS (version 9.4; SAS Institute). This analysis included 4,731 sexually active, HIV-negative Hispanic/Latino MSM interviewed during three cross-sectional data collection cycles (2011, N = 1,581; 2014, N = 1,479; and 2017, N = 1,671) in 19 urban areas. Overall during the preceding 12 months, the prevalence of condomless anal sex ** https://aidsinfo.nih.gov/news/1254/fda-approves-first-drug-for-reducing-therisk-of-sexually-acquired-hiv-infection.
increased from 63% in 2011 to 74% in 2017, and the prevalence of PrEP use increased from 3% in 2014 to 24% in 2017 (Table 1) ; and Seattle, Washington. † Numbers might not sum to total because of missing data; percentages might not sum to 100 because of rounding. § Chi-square is testing whether the distribution of characteristics within a column changed temporally. ¶ Data regarding PrEP use before 2014 are unavailable. ** Defined as condomless anal sex without having taken PrEP at any time during the previous 12 months.

Discussion
PrEP use overall has increased among all Hispanic groups, offsetting declines in condom use. However, sexual behavioral HIV acquisition risk among Hispanic/Latino MSM differed by place of birth and years of residence in the United States. Recent residents might benefit from improved HIV prevention education and services, including access to PrEP and condoms. Further, non-U.S.-born Hispanic/Latino MSM, regardless of duration of U.S. residence, might encounter more barriers to PrEP use than do their U.S.-born counterparts (6). Hispanic/Latino MSM in the U.S. who prefer to use educational materials in Spanish language might be at a disadvantage for learning about PrEP and how to access it because such materials might be sparse (7). In addition to addressing typical barriers to PrEP use among all MSM (e.g., cost of care and stigma), HIV prevention programs and services that support Hispanic/Latino MSM, who are all facing disparities in PrEP use (8), might benefit from offering culturally and linguistically appropriate linkage to PrEP. CDC's Let's Stop HIV Together † † initiative has developed multiple prevention campaigns that reach MSM (e.g., Start Talking. Stop HIV § § and Prescribe HIV Prevention ¶ ¶ ) and promote PrEP awareness and use for Spanish speakers. In addition, The Latino Commission on AIDS coordinates the National Latinx AIDS Awareness Day*** observance to distribute HIV testing kits and information regarding prevention services such as PrEP though community-based organizations, health departments, and leaders among Hispanic/Latino communities In addition to other barriers to HIV prevention typically faced by all MSM (e.g., cost of care and stigma), tailoring PrEP strategies for non-U.S.-born Hispanic/Latino MSM to include improving Spanish-language materials and culturally competent patient navigation services and increasing awareness of drug assistance programs and other support services, might help reduce risk for HIV among this population.
The findings in this report are subject to at least five limitations. First, years of U.S. residence was used as a proxy for acculturation; other indicators of acculturation were unavailable for analysis. Although broadly delineating between nativity and acculturation highlights selected cultural complexities within the Hispanic/ Latino MSM population, categorization into three groups remains † † https://www.cdc.gov/stophivtogether/index.html. § § https://www.cdc.gov/stophivtogether/campaigns/start-talking-stop-hiv/ index.html. ¶ ¶ https://www.cdc.gov/stophivtogether/campaigns/prescribe-hiv-prevention/ index.html. *** http://nlaad.org/.  an oversimplification of the diversity and various challenges these men face. Analysis by specific nation of birth or years of U.S. residence as a continuous variable was not possible in this study. Second, measures of PrEP use changed from 2014 to 2017; specifically, PrEP use was more narrowly defined in 2017 than in 2014. † † † Although PrEP use and condomless anal sex were both 12-month measures, the two might not have coincided, which might have resulted in an underestimation of the percentage of unprotected anal sex. Third, NHBS is not nationally representative, and data were not weighted to account for the complex sampling methods. Therefore, these results are not generalizable † † † In 2014, participants were asked whether, in the past 12 months, they had taken anti-HIV medicines before sex because they thought it would keep them from getting HIV. In 2017, participants were asked whether, in the past 12 months, they had taken PrEP (i.e., an antiretroviral medicine such as Truvada, that is taken for months or years by a person who is HIV-negative) to reduce the risk for getting HIV.
to all Hispanic/Latino MSM or to all geographic areas. Fourth, the analysis excluded interview data from San Juan, Puerto Rico, because of public health differences between Puerto Rico and the 50 states and District of Columbia (e.g., access to Medicaid and the limited number of PrEP providers). In 2017, 71% of MSM interviewed in Puerto Rico reported condomless anal sex, but only 4% reported using PrEP (9). Finally, data regarding selfreported behaviors, which were asked about among participants for a 12-month period, might be subject to recall error or social desirability bias, which can lead to overreporting PrEP use or underreporting condomless anal sex. The proposed Ending the HIV Epidemic § § § initiative highlights MSM and Hispanics/Latinos as priority populations for reaching to achieve national HIV prevention goals (10).
