Montebatsi M , Lavoie MC , Blanco N , Marima R , Sebina K , Mangope J , Ntwayagae O , Whittington A , Letebele M , Lekone P , Hess KL , Thomas V , Ramaabya D , Ramotsababa M , Stafford KA , Ndwapi N . AIDS 2021 36 (4) 533-538 BACKGROUND: In 2019, the Botswana Ministry of Health and Wellness (MOHW) implemented an HIV national Reboot program, which was needed for refocusing and intensifying efforts for achieving epidemic control. The strategies deployed as part of Reboot were reviewed and evaluated for their effect on same-day and within-seven-days (fast-track initiation) antiretroviral therapy (ART) initiation among adults newly identified with HIV. METHODS: We conducted a retrospective cohort analysis of patients aged 18 years or older who were newly diagnosed with HIV from October 2018 to September 2019 across 41 health facilities. We used generalized linear mixed models, adjusting for clustering by facility, to assess the association of the Reboot with same-day or within-seven-days ART initiation (fast-track initiation). RESULTS: From October 2018 to January 2019, 28% (636/2,269) of newly diagnosed HIV patients were initiated the same day of diagnosis, and 56% (1,260/2,269) were initiated within seven days. Following the launch of Reboot (February to September 2019), 59% (2,092/3,553) were initiated the same day of diagnosis, and 77% (2,752/3,553) were initiated within seven days. Clients were 2.08 (aRR 95% CI 1.79-2.43) times more likely to be initiated the same day of diagnosis and 1.39 (aRR 95% CI 1.28-1.52) times more likely to be initiated within seven days than before Reboot after adjusting for sex and age. CONCLUSION: In Botswana, a multifaceted national intervention improved timely ART initiation. Identifying and implementing different client-centered strategies to facilitate ART initiation is critical to preventing AIDS-related complications and prevent ongoing transmission. |
HIV prevalence among women who exchange sex for money or drugs - 4 U.S. cities
Nerlander LM , Handanagic S , Hess KL , Lutnick A , Agnew-Brune CB , Hoots BE , Braunstein SL , Glick SN , Higgins E , Padgett P , Schuette SM , Broz D , Ivy W3rd , Smith A , Thorson A , Paz-Bailey G . J Acquir Immune Defic Syndr 2020 84 (4) 345-354 BACKGROUND: Limited data exist in the United States on the prevalence of HIV among women who exchange sex. SETTING: We estimate HIV prevalence of women who exchange sex from a 2016 survey in Chicago, Detroit, Houston, and Seattle and compare it with the prevalence of HIV among women of low socioeconomic status (SES), who did not exchange sex, and women in the general population. METHODS: Women who exchange sex were recruited via respondent-driven sampling among some cities participating in National HIV Behavioral Surveillance, interviewed, and offered HIV testing. We estimate HIV prevalence and, using prevalence ratios, compare it with the prevalence among women of low SES who did not exchange sex in the 2013 National HIV Behavioral Surveillance cycle, and to women in the general population estimated using 2015 National HIV Surveillance data. RESULTS: One thousand four hundred forty women reported exchange sex in 2016. Aggregated HIV prevalence was 4.9% [95% confidence interval (CI): 2.7 to 7.1] among women who exchanged sex, 1.6% (95% CI: 0.3 to 2.8) among women of low SES who did not exchange sex, and 0.6% (95% CI: 0.5% to 0.6%) among women in the general population. HIV prevalence among women who exchanged sex was 3.1 times (95% CI: 1.6 to 5.9) as high as among women of low SES who did not exchange sex, and 8.8 times (95% CI: 7.0 to 11.1) as high as among women in the general population. CONCLUSION: HIV prevalence was significantly higher among women who exchanged sex compared with women in the general population and women of low SES who did not exchange sex. |
Receptive anal sex contributes substantially to heterosexually-acquired HIV infections among at-risk women in twenty US cities: results from a modelling analysis
Elmes J , Silhol R , Hess KL , Gedge LM , Nordsletten A , Staunton R , Anton P , Shacklett B , McGowan I , Dang Q , Adimora AA , Dimitrov DT , Aral S , Handanagic S , Paz-Bailey G , Boily MC . Am J Reprod Immunol 2020 84 (2) e13263 PROBLEM: Receptive anal intercourse (RAI) is more efficient than receptive vaginal intercourse (RVI) at transmitting HIV, but its contribution to heterosexually-acquired HIV infections among at-risk women in the US is unclear. METHOD OF STUDY: We analysed sexual behaviour data from surveys of 9,152 low-income heterosexual women living in 20 cities with high rates of HIV conducted in 2010 and 2013 as part of US National HIV Behavioral Surveillance. We estimated RAI prevalence (past-year RAI) and RAI fraction (fraction of all sex acts (RVI and RAI) at the last sexual episode that were RAI among those reporting past-year RAI) overall and by key demographic characteristics. These results and HIV incidence were used to calibrate a risk-equation model to estimate the population attributable fraction of new HIV infections due to RAI (PAFRAI ) accounting for uncertainty in parameter assumptions. RESULTS: RAI prevalence (overall: 32%, city range: 19-60%) and RAI fraction (overall: 27%, city-range: 18-34%) were high overall and across cities, and positively associated with exchange sex. RAI accounted for an estimated 41% (uncertainty range: 18-55%) of new infections overall (city range: 21-57%). Variability in PAFRAI estimates was most influenced by uncertainty in the estimate of the per-act increased risk of RAI relative to RVI and the number of sex acts. CONCLUSIONS: RAI may contribute disproportionately to new heterosexually-acquired HIV infections among at-risk low-income women in the US, meaning that tools to prevent HIV transmission during RAI are warranted. Number of RVI and RAI acts should also be collected to monitor heterosexually-acquired HIV infections. |
Racial and ethnic disparities in sustained viral suppression and transmission risk potential among persons aged 13-29 years living with diagnosed HIV infection, United States, 2016
Crepaz N , Dong X , Hess KL , Bosh K . J Acquir Immune Defic Syndr 2020 83 (4) 334-339 BACKGROUND: In 2016, persons aged 13-29 years represented 23.1% of the U.S. population, yet accounted for 41.7% of HIV diagnoses. Racial/ethnic minorities are disproportionally affected by HIV. Sustaining viral suppression helps persons living with diagnosed HIV infection (PLWDH) stay healthy and reduces the risk of transmitting HIV. We examined racial/ethnic disparities in sustained viral suppression and transmission risk potential among PLWDH aged 13-29 years. METHODS: We analyzed data from the National HIV Surveillance System reported through December 2018 from 42 jurisdictions with complete laboratory reporting. We included persons aged 13-29 years who received an HIV diagnosis by December 31, 2015, most recently resided in one of the 42 jurisdictions, and were alive at the end of 2016. Sustained viral suppression was defined as viral load <200 copies/mL for all tests in 2016. Transmission risk potential was estimated using the number of days with viral loads >1,500 copies/mL. RESULTS: Of the 90,812 PLWDH aged 13-29 years included in the analysis, 41.5% had sustained viral suppression in 2016. Across age, sex, and most transmission categories, blacks had the lowest prevalence of sustained viral suppression. Among the 28,154 who were in care but without sustained viral suppression, the average number of days with viral load >1,500 copies/mL was 206 days (56.4% of the 12-month period). CONCLUSION: Sustained viral suppression was suboptimal and transmission risk potential was high for PLWDH aged 13-29 years. Racial/ethnic disparities were apparent, calling for strengthening tailored interventions to improve care outcomes. |
Improving HIV surveillance data by using the ATra Black Box System to assist regional deduplication activities
Ocampo JMF , Hamp A , Rhodes A , Smart JC , Pemmaraju R , Poschman K , Hess KL , Bhattacharjee R , Flynn C , Anderson BJ , Dowling JE , Maccormack F , Doshi R , Lum G , Maddox L , Moncur B , Barnhart JE , Maxwell J , Aurand SB , Hogan V , Wills D , Prowell S , Kassaye SG , Karn HE , Laffoon BT , Collmann J . J Acquir Immune Defic Syndr 2019 82 Suppl 1 S13-s19 BACKGROUND: Focused attention on Data to Care underlines the importance of high-quality HIV surveillance data. This study identified the number of total duplicate and exact duplicate HIV case records in 9 separate Enhanced HIV/AIDS Reporting System (eHARS) databases reported by 8 jurisdictions and compared this approach to traditional Routine Interstate Duplicate Review resolution. METHODS: This study used the ATra Black Box System and 6 eHARS variables for matching case records across jurisdictions: last name, first name, date of birth, sex assigned at birth (birth sex), social security number, and race/ethnicity, plus 4 system-calculated values (first name Soundex, last name Soundex, partial date of birth, and partial social security number). RESULTS: In approximately 11 hours, this study matched 290,482 cases from 799,326 uploaded records, including 55,460 exact case pairs. Top case pair overlaps were between NYC and NYS (51%), DC and MD (10%), and FL and NYC (6%), followed closely by FL and NYS (4%), FL and NC (3%), DC and VA (3%), and MD and VA (3%). Jurisdictions estimated that they realized a combined 135 labor hours in time efficiency by using this approach compared with manual methods previously used for interstate duplication resolution. DISCUSSION: This approach discovered exact matches that were not previously identified. It also decreased time spent resolving duplicated case records across jurisdictions while improving accuracy and completeness of HIV surveillance data in support of public health program policies. Future uses of this approach should consider standardized protocols for postprocessing eHARS data. |
Estimating national rates of HIV infection among men who have sex with men, persons who inject drugs and heterosexuals in the United States
Crepaz N , Hess KL , Purcell DW , Hall HI . AIDS 2018 33 (4) 701-708 BACKGROUND: Calculating national rates of HIV diagnosis, incidence, and prevalence can quantify disease burden and is important for planning and evaluating programs. We calculated HIV rates among men who have sex with men (MSM), persons who inject drugs (PWID), and heterosexuals in 2010 and 2015. METHODS: We used proportion estimates of the United States population classified as MSM, PWID, and heterosexuals along with census data to calculate the population sizes which were used as the denominators for calculating HIV rates. The numerators (HIV diagnosis, incidence, and prevalence) were based on data submitted to the National HIV Surveillance System through June 2017. RESULTS: The estimated HIV diagnosis and incidence rates in 2015 were 574.7 and 583.6 per 100,000 MSM; 34.3 and 32.7 per 100,000 PWID; and 4.1 and 3.8 per 100,000 heterosexuals. The estimated HIV prevalence in 2015 was 12,372.9 per 100,000 MSM; 1,937.2 per 100,000 PWID; and 126.7 per 100,000 heterosexuals. The HIV diagnosis rates decreased from 2010 to 2015 in all three transmission categories. Blacks had the highest HIV diagnosis rates at both time points. The HIV incidence rates decreased among white MSM, MSM aged 13-24 years, PWID overall, and male and female heterosexuals; however, it increased among MSM aged 25-34 years. CONCLUSIONS: The estimated HIV diagnosis and HIV infection rates decreased for several transmission categories as well as race/ethnicity and age subgroups. MSM continue to be disproportionately affected. Disparities remain and have widened for some groups. Efforts are needed to strengthen prevention, care, and supportive services for all persons with HIV infection. |
HIV viral suppression, 37 states and the District of Columbia, 2014
Hess KL , Hall HI . J Community Health 2017 43 (2) 338-347 Achieving viral suppression among HIV-positive persons is a critical component of HIV treatment and prevention, because it leads to improved health outcomes for the individual and reduced risk of HIV transmission. There is wide variation in viral suppression across jurisdictions, races/ethnicities, age groups, and transmission risk groups. This analysis uses HIV surveillance data to examine rates of viral suppression among people living with diagnosed HIV (PLWDH) in 38 jurisdictions with complete lab reporting. Among people who received a diagnosis in 2014, the percentage with viral suppression within 12 months of diagnosis and the average time to viral suppression was assessed. Overall, among PLWDH in 2014, 57.9% were virally suppressed, and, among people with HIV diagnosed in 2014, 68.2% were suppressed within 12 months of diagnosis with an average time to suppression of 6.9 months. All outcomes varied by jurisdiction, but most had similar patterns of disparities with a few exceptions. These data highlight the need for tailored interventions at the local level. In addition, jurisdictions with relatively low viral suppression among particular groups could adapt effective interventions from jurisdictions who have higher rates of suppression. |
Exchange sex and HIV infection among women who inject drugs - 20 US cities, 2009
Nerlander LM , Hess KL , Rose CE , Sionean C , Thorson A , Broz D , Paz-Bailey G . J Acquir Immune Defic Syndr 2017 75 Suppl 3 S333-s340 BACKGROUND: Women who inject drugs and who also exchange sex are at increased risk for HIV infection, but data on this population in the United States remain sparse. METHODS: This study assessed the prevalence of exchanging sex for money or drugs among women who inject drugs using data from the 2009 US National HIV Behavioral Surveillance (NHBS) system. Prevalence of being HIV-positive (testing positive in NHBS), HIV-positive-unaware (reporting being HIV-negative or unknown status but testing positive in NHBS), and risk behaviors and use of services were compared between women who did and did not exchange sex. The association between exchange sex and being HIV-positive-unaware of the infection was examined using multivariate Poisson models with robust standard errors. RESULTS: Among 2305 women who inject drugs, 39% reported receiving things like money or drugs from ≥1 male partners in exchange for oral, vaginal, or anal sex in the previous 12 months. Women who exchanged sex were more likely to be unemployed, homeless, lack health insurance, have multiple condomless vaginal or anal sex partners, and receptively share syringes. In multivariate analysis, exchange sex was associated with being HIV-positive-unaware (adjusted prevalence ratio 1.97, 95% confidence intervals: 1.31 to 2.97). CONCLUSIONS: Prevalence of exchange sex was high in this population. Women who exchange sex were more likely to be socially disadvantaged, report sexual and injection risk, and be HIV-positive-unaware. They represent an important group to reach with HIV prevention, testing, and care services. |
Trends in sexual behavior among men who have sex with men (MSM) in high-income countries, 1990-2013: A systematic review
Hess KL , Crepaz N , Rose C , Purcell D , Paz-Bailey G . AIDS Behav 2017 21 (10) 2811-2834 HIV diagnoses among men who have sex with men (MSM) have been increasing in several high-income countries. A better understanding of the sexual behavior trends among MSM can be useful for informing HIV prevention. We conducted a systematic review of studies that examined behavioral trends (1990-2013) in any condomless anal sex, condomless anal sex with an HIV-discordant partner, and number of partners. Studies included come from the United States, Europe, and Australia. We found increasing trends in condomless anal sex and condomless anal sex with an HIV-discordant partner, and a decreasing trend in number of partners. The increase in condomless anal sex may help to explain the increase in HIV infections. More explanatory research is needed to provide insight into factors that contribute to these behavior trends. Continuous monitoring of HIV, risk behaviors, and use of prevention and treatment is needed to evaluate prevention efforts and monitor HIV transmission risk. |
Lifetime risk of a diagnosis of HIV infection in the United States
Hess KL , Hu X , Lansky A , Mermin J , Hall HI . Ann Epidemiol 2017 27 (4) 238-243 PURPOSE: To estimate lifetime risk of receiving an HIV diagnosis in the United States if existing infection rates continue. METHODS: We used mortality, census, and HIV surveillance data for 2010 to 2014 to calculate age-specific probabilities of an HIV diagnosis. The probabilities were applied to a hypothetical cohort of 10 million live births to estimate lifetime risk. RESULTS: Lifetime risk was 1 in 68 for males and 1 in 253 for females. Lifetime risk for men was 1 in 22 for blacks, 1 in 51 for Hispanic/Latinos, and 1 in 140 for whites; and for women was 1 in 54 for blacks, 1 in 256 for Hispanic/Latinas, and 1 in 941 for whites. By risk group, the highest risk was among men who have sex with men (1 in 6) and the lowest was among male heterosexuals (1 in 524). Most of the states with the highest lifetime risk were in the South. CONCLUSIONS: The estimates highlight different risks across populations and the need for continued improvements in prevention and treatment. They can also be used to communicate the risk of HIV infection and increase public awareness of HIV. |
Vital Signs: Trends in HIV diagnoses, risk behaviors, and prevention among persons who inject drugs - United States
Wejnert C , Hess KL , Hall HI , Van Handel M , Hayes D , Fulton P Jr , An Q , Koenig LJ , Prejean J , Valleroy LA . MMWR Morb Mortal Wkly Rep 2016 65 (47) 1336-1342 BACKGROUND: Persons who inject drugs (PWID) are at increased risk for poor health outcomes and bloodborne infections, including human immunodeficiency virus (HIV), hepatitis C virus and hepatitis B virus infections. Although substantial progress has been made in reducing HIV infections among PWID, recent changes in drug use could challenge this success. METHODS: CDC used National HIV Surveillance System data to analyze trends in HIV diagnoses. Further, National HIV Behavioral Surveillance interviews of PWID in 22 cities were analyzed to describe risk behaviors and use of prevention services among all PWID and among PWID who first injected drugs during the 5 years before their interview (new PWID). RESULTS: During 2008-2014, HIV diagnoses among PWID declined in urban and nonurban areas, but have leveled off in recent years. Among PWID in 22 cities, during 2005-2015, syringe sharing decreased by 34% among blacks/African Americans (blacks) and by 12% among Hispanics/Latinos (Hispanics), but remained unchanged among whites. The racial composition of new PWID changed during 2005-2015: the percentage who were black decreased from 38% to 19%, the percentage who were white increased from 38% to 54%, and the percentage who were Hispanic remained stable. Among new PWID interviewed in 2015, whites engaged in riskier injection behaviors than blacks. CONCLUSIONS: Decreases in HIV diagnoses among PWID indicate success in HIV prevention. However, emerging behavioral and demographic trends could reverse this success. IMPLICATIONS FOR PUBLIC HEALTH PRACTICE: Access to comprehensive prevention services is essential for all PWID. Syringe services programs reduce syringe sharing and can help PWID access prevention and treatment services for HIV and other bloodborne diseases, such as hepatitis C and hepatitis B. |
Association between enacted stigma and HIV-related risk behavior among MSM, National HIV Behavioral Surveillance System, 2011
Balaji AB , Bowles KE , Hess KL , Smith JC , Paz-Bailey G . AIDS Behav 2016 21 (1) 227-237 MSM bear a disproportionate burden of the HIV epidemic. Enacted stigma (overt negative actions) against sexual minorities may play an important role in increasing HIV risk among this population. Using data from the 2011 National HIV Behavioral Surveillance system, MSM cycle, we examined the independent associations between three measures of enacted stigma (verbal harassment, discrimination, physical assault) and engagement in each of four HIV-related risk behaviors as outcomes: condomless anal intercourse (CAI) at last sex with a male partner of HIV discordant or unknown status and, in the past 12 months, CAI with a male partner, ≥4 male sex partners, and exchange sex. Of 9819 MSM, 32% experienced verbal harassment in the past 12 months, 23% experienced discrimination, and 8% experienced physical assault. Discordant CAI at last sex with a male partner was associated with previous discrimination and physical assault. Past 12 month CAI with a male partner, ≥4 male sex partners, and exchange sex were each associated with verbal harassment, discrimination, and physical assault. These findings indicate that a sizable proportion of MSM report occurrences of past 12 month enacted stigma and suggest that these experiences may be associated with HIV-related risk behavior. Addressing stigma towards sexual minorities must involve an integrated, multi-faceted approach, including interventions at the individual, community, and societal level. |
Syphilis trends among men who have sex with men in the United States and western Europe: A systematic review of trend studies published between 2004 and 2015
Abara WE , Hess KL , Neblett Fanfair R , Bernstein KT , Paz-Bailey G . PLoS One 2016 11 (7) e0159309 Globally, men who have sex with men (MSM) are disproportionately burdened with syphilis. This review describes the published literature on trends in syphilis infections among MSM in the US and Western Europe from 1998, the period with the fewest syphilis infections in both geographical areas, onwards. We also describe disparities in syphilis trends among various sub-populations of MSM. We searched electronic databases (Medline, Embase, Global Health, PsychInfo, CAB Abstracts, CINAHL, Sociological Abstracts, Web of Science, Cochrane Library, and LILACS) for peer-reviewed journal articles that were published between January 2004 and June 2015 and reported on syphilis cases among MSM at multiple time points from 1998 onwards. Ten articles (12 syphilis trend studies/reports) from the US and eight articles (12 syphilis trend studies/reports) from Western Europe were identified and included in this review. Taken together, our findings indicate an increase in the numbers and rates (per 100,000) of syphilis infections among MSM in the US and Western Europe since 1998. Disparities in the syphilis trends among MSM were also noted, with greater increases observed among HIV-positive MSM than HIV-negative MSM in both the US and Western Europe. In the US, racial minority MSM and MSM between 20 and 29 years accounted for the greatest increases in syphilis infections over time whereas White MSM accounted for most syphilis infections over time in Western Europe. Multiple strategies, including strengthening and targeting current syphilis screening and testing programs, and the prompt treatment of syphilis cases are warranted to address the increase in syphilis infections among all MSM in the US and Western Europe, but particularly among HIV-infected MSM, racial minority MSM, and young MSM in the US. |
Exchange sex and HIV infection among men who have sex with men: 20 US cities, 2011
Nerlander L M , Hess KL , Sionean C , Rose C E , Thorson A , Broz D , Paz-Bailey G . AIDS Behav 2016 21 (8) 2283-2294 This study assessed the prevalence of exchanging sex for money or drugs among men who have sex with men (MSM) in the 2011 US National HIV Behavioral Surveillance system. Prevalence of HIV, being HIV-positive but unaware (HIV-positive-unaware), risk behaviors and use of services were compared between MSM who did and did not receive money or drugs from one or more casual male partners in exchange for oral or anal sex in the past 12 months. Among 8411 MSM, 7.0 % exchanged sex. MSM who exchanged sex were more likely to be non-Hispanic black, live in poverty, have injected drugs, have multiple condomless anal sex partners, be HIV-positive and be HIV-positive-unaware. In multivariable analysis, exchange sex was associated with being HIV-positive-unaware (aPR 1.34, 95 % CI 1.05-1.69) after adjusting for race/ethnicity, age, education, poverty, and injecting drugs. MSM who exchange sex represent an important group to reach with HIV prevention, testing, and care services as they were more likely to report behavioral risk factors that put them at risk of HIV. |
Prevalence and correlates of heterosexual anal intercourse among men and women, 20 U.S. cities
Hess KL , DiNenno E , Sionean C , Ivy W , Paz-Bailey G . AIDS Behav 2016 20 (12) 2966-2975 Heterosexual anal intercourse (HAI) is not an uncommon behavior and it confers a higher risk of HIV transmission than vaginal intercourse. We examined data from heterosexuals recruited in 20 US cities for the 2013 National HIV Behavioral Surveillance system. We assessed correlates of reporting HAI in the previous year. Then, among people reporting HAI in the past year, we assessed what event-level factors are associated with having HAI at last sex. Thirty percent of women and 35 % of men reported HAI in the past year. Among people who had HAI in the past year, those who had HAI at last sex were more likely to have a partner who was HIV-positive or of unknown status or to have exchanged money or drugs for sex at last sex. Information that highlights the risk of HIV transmission associated with HAI would complement existing HIV prevention messages focused on heterosexuals in the U.S. |
Age-specific race and ethnicity disparities in HIV infection and awareness among men who have sex with men - 20 U.S. cities, 2008 to 2014
Wejnert C , Hess KL , Rose CE , Balaji A , Smith JC , Paz-Bailey G . J Infect Dis 2015 213 (5) 776-83 BACKGROUND: Over half of U.S. HIV infections occur among men who have sex with men (MSM). Among MSM, 16% of estimated new infections in 2010 occurred among black MSM <25 years old. METHODOLOGY: We analyzed National HIV Behavioral Surveillance MSM data from 20 cities. Poisson models were used to test racial disparities by age in HIV prevalence, HIV awareness, and sex behaviors among MSM in 2014. Data from 2008, 2011, and 2014 were used to examine how racial/ethnic disparities changed across time. RESULTS: While black MSM did not report greater sexual risk than other MSM, they were most likely to be infected with HIV and least likely to know it. Among black MSM aged 18-24 years tested in 2014, 26% were HIV-positive. Among white MSM aged 18-24 years tested in 2014, 3% were HIV-positive. The disparity in HIV prevalence between black and white MSM increased from 2008 to 2014, especially among young MSM. CONCLUSIONS: Disparities in HIV prevalence between black and white MSM continue to increase. Black MSM may be infected with HIV at younger ages than other MSM and may benefit from prevention efforts that address the needs of younger men. |
Binge drinking and risky sexual behavior among HIV-negative and unknown HIV status men who have sex with men, 20 US cities
Hess KL , Chavez PR , Kanny D , DiNenno E , Lansky A , Paz-Bailey G . Drug Alcohol Depend 2015 147 46-52 BACKGROUND: Men who have sex with men (MSM) represent over half of new HIV infections in the United States. It is important to understand the factors associated with engaging in risky sexual behavior to develop effective prevention interventions. Binge drinking (≥5 drinks on ≥1 occasion) is the most common form of excessive alcohol consumption. This study examines the relationship between binge drinking and sexual risk behaviors among MSM who are current drinkers and who were either HIV-negative or unaware of their HIV status. METHODS: Using the 2011 National HIV Behavioral Surveillance system and multivariable Poisson models with robust error estimates, we assessed the association between binge drinking and sexual risk behaviors among current drinkers. Prevalence ratios (PR) and 95% confidence intervals (CI) are presented. RESULTS: Overall, 85% of MSM were current drinkers, and 59% of MSM who drank reported ≥1 episode of binge drinking in the preceding 30 days. In multivariable models, binge drinking was associated with condomless anal intercourse (CAI) at last sex with an HIV-positive or unknown status partner (receptive: PR 1.3, 95% CI 1.1-1.6; insertive: PR 1.2, 95% CI 1.0-1.4), having exchanged sex for money or drugs at last sex (PR: 1.4, 95% CI 1.1-1.7), having concurrent partners in the past year (PR: 1.1, 95% CI 1.1-1.2), and having more CAI partners in the past year (PR: 1.2, 95% CI 1.0-1.4) compared to non-binge drinkers. CONCLUSIONS: Evidence-based strategies for reducing binge drinking could help reduce risky sexual behavior among MSM. |
HIV risk, prevention, and testing behaviors among heterosexuals at increased risk for HIV infection - National HIV Behavioral Surveillance System, 21 U.S. cities, 2010
Sionean C , Le BC , Hageman K , Oster AM , Wejnert C , Hess KL , Paz-Bailey G . MMWR Surveill Summ 2014 63 Suppl 14 (14) 1-39 PROBLEM/CONDITION: At the end of 2010, an estimated 872,990 persons in the United States were living with a diagnosis of human immunodeficiency virus (HIV) infection. Approximately one in four of the estimated HIV infections diagnosed in 2011 were attributed to heterosexual contact. Heterosexuals with a low socioeconomic status (SES) are disproportionately likely to be infected with HIV. REPORTING PERIOD: June-December 2010. DESCRIPTION OF SYSTEM: The National HIV Behavioral Surveillance System (NHBS) collects HIV prevalence and risk behavior data in selected metropolitan statistical areas (MSAs) from three populations at high risk for HIV infection: men who have sex with men, injecting drug users, and heterosexuals at increased risk for HIV infection. Data for NHBS are collected in rotating cycles in these three different populations. For the 2010 NHBS cycle among heterosexuals, men and women were eligible to participate if they were aged 18-60 years, lived in a participating MSA, were able to complete a behavioral survey in English or Spanish, and reported engaging in vaginal or anal sex with one or more opposite-sex partners in the 12 months before the interview. Persons who consented to participate completed an interviewer-administered, standardized questionnaire about HIV-associated behaviors and were offered anonymous HIV testing. Participants were sampled using respondent-driven sampling, a type of chain-referral sampling. Sampling focused on persons of low SES (i.e., income at the poverty level or no more than a high school education) because results of a pilot study indicated that heterosexual adults of low SES were more likely than those of high SES to be infected with HIV. To assess risk and testing experiences among persons at risk for acquiring HIV infection through heterosexual sex, analyses excluded participants who were not low SES, those who reported ever having tested positive for HIV, and those who reported recent (i.e., in the 12 months before the interview) male-male sex or injection drug use. This report summarizes unweighted data regarding HIV-associated risk, prevention, and testing behaviors from 9,278 heterosexual men and women interviewed in 2010 (the second cycle of NHBS data collection among heterosexuals). RESULTS: The median age of participants was 35 years; 47% were men. The majority of participants were black or African American (hereafter referred to as black) (72%) or Hispanic/Latino (21%). Most participants (men: 88%; women: 90%) reported having vaginal sex without a condom with one or more opposite-sex partners in the past 12 months; approximately one third (men: 30%; women: 29%) reported anal sex without a condom with one or more opposite-sex partners. The majority of participants (59%) reported using noninjection drugs in the 12 months before the interview; nearly one in seven (15%) had used crack cocaine. Although most participants (men: 71%; women: 77%) had ever been tested for HIV, this percentage was lower among Hispanic/Latino participants (men: 52%; women: 62%). Approximately one third (34%) of participants reported receiving free condoms in the 12 months before the interview; 11% reported participating in a behavioral HIV prevention program. INTERPRETATION: A substantial proportion of heterosexuals interviewed for the 2010 NHBS heterosexual cycle reported engaging in behaviors that increase the risk for HIV infection. However, HIV testing was suboptimal among the overall sample, including among groups disproportionately affected by HIV infection (i.e., blacks and Hispanics/Latinos). PUBLIC HEALTH ACTION: Increasing coverage of HIV testing and other HIV prevention services among heterosexuals at increased risk is important, especially among groups disproportionately affected by HIV infection, such as blacks and Hispanics/Latinos. The National HIV/AIDS Strategy for the United States delineates a coordinated national response to reduce infections and HIV-related health disparities among disproportionately affected groups. NHBS data can guide national and local planning efforts to maximize the impact of HIV prevention programs. |
