Abstract
Opioid use disorder is complex and not easily quantified among US populations because there are no dedicated reporting systems in place. We review indicators of opioid use disorder available at the state and county (human immunodeficiency virus diagnoses among people who inject drugs, hepatitis C diagnosis in people <50 years, opioid overdose death rates, and opioid prescription rate). The interpretation of the ecological results and the visualization of indicators at the local level will provide actionable insights for clinicians and public health officials seeking to mitigate the consequences of opioid use disorder at the patient and community levels.

Sullivan PS, Satcher Johnson A, Pembleton ES, Stephenson R, Justice AC, Althoff KN, Bradley H, Castel AD, Oster AM, Rosenberg ES, Mayer KH, Beyrer C. Epidemiology of HIV in the USA: epidemic burden, inequities, contexts, and responses. Lancet 2021; 397:1095-1106. [PMID: 33617774 DOI: 10.1016/s0140-6736(21)00395-0] [Citation(s) in RCA: 145] [Impact Index Per Article: 48.3] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/07/2019] [Revised: 08/09/2020] [Accepted: 09/25/2020] [Indexed: 12/17/2022]
Abstract
The HIV epidemic in the USA began as a bicoastal epidemic focused in large cities but, over nearly four decades, the epidemiology of HIV has changed. Public health surveillance data can inform an understanding of the evolution of the HIV epidemic in terms of the populations and geographical areas most affected. We analysed publicly available HIV surveillance data and census data to describe: current HIV prevalence and new HIV diagnoses by region, race or ethnicity, and age; trends in HIV diagnoses over time by HIV acquisition risk and age; and the distribution of HIV prevalence by geographical area. We reviewed published literature to explore the reasons for the current distribution of HIV cases and important disparities in HIV prevalence. We identified opportunities to improve public health surveillance systems and uses of data for planning and monitoring public health responses. The current US HIV epidemic is marked by geographical concentration in the US South and profound disparities between regions and by race or ethnicity. Rural areas vary in HIV prevalence; rural areas in the South are more likely to have a high HIV prevalence than rural areas in other US Census regions. Ongoing disparities in HIV in the South are probably driven by the restricted expansion of Medicaid, health-care provider shortages, low health literacy, and HIV stigma. HIV diagnoses overall declined in 2009-18, but HIV diagnoses among individuals aged 25-34 years increased during the same period. HIV diagnoses decreased for all risk groups in 2009-18; among men who have sex with men (MSM), new diagnoses decreased overall and for White MSM, remained stable for Black MSM, and increased for Hispanic or Latino MSM. Surveillance data indicate profound and ongoing disparities in HIV cases, with disproportionate impact among people in the South, racial or ethnic minorities, and MSM.

Abstract
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 USA is unclear. METHOD OF STUDY We analysed sexual behaviour data from surveys of 9152 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 Receptive anal intercourse 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. CONCLUSION Receptive anal intercourse may contribute disproportionately to new heterosexually acquired HIV infections among at-risk low-income women in the USA, meaning that tools to prevent HIV transmission during RAI are warranted. The number of RVI and RAI acts should also be collected to monitor heterosexually acquired HIV infections.

Abstract
BACKGROUND Studies have documented high human immunodeficiency virus (HIV) prevalence among transwomen in the United States; however, to our knowledge, no studies have documented trends in HIV prevalence in this population. METHODS We used respondent-driven sampling to sample transwomen in San Francisco for 3 HIV prevalence and behavioral surveys in 2010, 2013, and 2016. Our analysis of point estimates and trends were weighted for the sampling method. RESULTS Human immunodeficiency virus prevalence by serological testing in the survey was 38.8% (95% confidence interval [CI], 32.4-45.2), 33.7% (95% CI, 25.9-41.5), and 31.6% (95% CI, 12.2-38.1) in 2010, 2013, and 2016, respectively. Disparities in higher HIV prevalence by black, Latino, and Asian race/ethnicity and lower education level persisted through 2016. CONCLUSIONS Based on a statistical test for trend, HIV prevalence among transwomen has remained high and stable from 2010 to 2016. Human immunodeficiency virus infection is still highest at 31.6% compared to any other group in San Francisco. We also observed that older transwomen had significantly higher odds of living with HIV than younger women over the last 2 waves of data collection. Taken together, these trends suggest that there is declining incidence of new HIV infections among low-income transwomen in San Francisco. Moreover, among transwomen, HIV disproportionately affects transwomen of color.

Abstract
Purpose: We assessed differences between gay and bisexual men in enacted stigma, and how the association between stigma and depressive symptoms may vary according to sexual orientation identity. Methods: Participants (671 gay and 331 bisexual men who have sex with men) in Baltimore's 2011 and 2014 National HIV Behavioral Surveillance completed an anonymous survey, including 3 enacted stigma dimensions and the Center for Epidemiologic Studies Depression Scale. Adjusted prevalence ratios were calculated through Generalized Estimating Equation models adjusting for theorized confounders (demographic, socioeconomic, and relational factors). Results: Bisexual men reported stigma experiences less frequently than did gay men (verbal harassment 22.7% vs. 32.3%, and discrimination 15.7% vs. 23.0%). Relevant depressive symptoms were reported by 43.1% of bisexual men and 34.2% of gay men (p < 0.001). Statistically significant differences in depressive symptoms between bisexual and gay men disappeared after adjusting for socioeconomic factors. The three enacted stigma dimensions were significantly associated with depressive symptoms, but their interaction with sexual orientation identity was not. Conclusion: This study confirms the association between enacted stigma and depressive symptoms among gay and bisexual men. However, sexual orientation identity did not modify this association as hypothesized. The bisexual men presented other psychosocial stressors that may explain their higher prevalence of depressive symptoms. The high levels of verbal harassment, discrimination, and physical assault reported by gay and bisexual men and their negative effect on mental health indicate the need to develop new effective public health strategies to avoid these consequences of homophobic and biphobic culture.

Abstract
Background Gay, bisexual, and other men who have sex with men (GBM) have the highest proportion of incident HIV infection. Pre-exposure prophylaxis (PrEP) use and screening for sexually transmitted infections (STIs) are primary HIV prevention strategies, however, uptake remains low. Social capital, collective resources generated through social connections, are associated with lower HIV risk and infection. We investigated social capital in association with PrEP indicators among GBM. Methods Analyses included (N = 376) GBM from the 2014 National HIV Behavioral Surveillance (NHBS) in New Orleans. Multiple regression methods assessed the association between one item within each of eight domains from the Onyx and Bullen Social Capital Scale and: awareness and willingness to use PrEP. Analyses are adjusted for age, race, education, sexual intercourse with women, and health insurance. Results Forty percent of GBM were 18–29 years, 52 percent White. Sixty percent were willing to use PrEP. Social capital was above 50 percent across 7 of 8 indicators. Community group participation (vs no participation) was associated with higher likelihoods of PrEP awareness (adjusted Prevalence Ratio [aPR] = 1.41, 95% Confidence Interval [CI] = 1.02, 1.95). None of the seven remaining social capital indicators were significantly associated with any of the PrEP outcomes. Conclusions Community groups and organizations could be targeted for interventions to increase uptake of HIV prevention strategies among GBM in New Orleans

Abstract
Despite previous empirical studies which have linked social capital to a number of health outcomes, few studies have investigated sub-group specific social capital among populations at increased risk for HIV infection such as gay, bisexual and other men who have sex with men (GBM). Many GBM of color belong to constructed families in which friends refer to each other with kinship terms such as parents and children. No studies have measured social capital provisions within constructed family networks. This study developed a preliminary instrument for assessing social capital among constructed families. The network level social capital scale incorporated the following theoretical domains hypothesized to define social capital derived from network membership: social influence, multiplex ties, heterogeneity, social cohesion, trust, quality of support, and compositional quality. A cross-sectional survey administered an eight-item scale to 131 GBM who belonged to constructed families. The factor structure and confirmatory factor analysis were assessed. Reliability was evaluated using Cronbach's alpha to measure internal consistency. A final single factor solution was obtained which was comprised of six items with high factor loadings. The resulting measures were highly correlated with an alpha of 0.84 and each factor loading was well above 0.3. This study assessed the psychometric properties of a preliminary network level social capital instrument among GBM in constructed families. Future studies may utilize or adopt this scale to measure network-level social capital within other populations.

Abstract
Gay, bisexual, and other men who have sex with men (MSM) represent more new HIV infections than all other at-risk populations. Many young black MSM belong to constructed families (i.e., the house ball community, gay families, and pageant families) which are often organized in a family structure with members referred to as parents and children. Many constructed families are associated with a family surname which is informally adopted by members. In some cases, however, constructed families do not identify with a collective family name. In 2014, 553 MSM were recruited through venue-based time-space sampling during the National HIV Behavioral Surveillance (NHBS) in New Orleans to complete a structured survey and HIV test. Black, Latino, and other race MSM were more likely to belong to constructed families in comparison to white MSM. In addition, participants who belonged to constructed families with a family name were more likely to engage in protective behaviors including wearing condoms at last sexual intercourse. Overall, younger, white MSM who did not belong to any social groups were more likely to engage in at least one risk behavior. These findings significantly contribute to understanding variations in HIV risk behavior among members of constructed families.

Abstract
Existing methods to estimate the prevalence of chronic hepatitis C (HCV) in New York City (NYC) are limited in scope and fail to assess hard-to-reach subpopulations with highest risk such as injecting drug users (IDUs). To address these limitations, we employ a Bayesian multi-parameter evidence synthesis model to systematically combine multiple sources of data, account for bias in certain data sources, and provide unbiased HCV prevalence estimates with associated uncertainty. Our approach improves on previous estimates by explicitly accounting for injecting drug use and including data from high-risk subpopulations such as the incarcerated, and is more inclusive, utilizing ten NYC data sources. In addition, we derive two new equations to allow age at first injecting drug use data for former and current IDUs to be incorporated into the Bayesian evidence synthesis, a first for this type of model. Our estimated overall HCV prevalence as of 2012 among NYC adults aged 20-59 years is 2.78% (95% CI 2.61-2.94%), which represents between 124,900 and 140,000 chronic HCV cases. These estimates suggest that HCV prevalence in NYC is higher than previously indicated from household surveys (2.2%) and the surveillance system (2.37%), and that HCV transmission is increasing among young injecting adults in NYC. An ancillary benefit from our results is an estimate of current IDUs aged 20-59 in NYC: 0.58% or 27,600 individuals.

Abstract
BACKGROUND We assess trends in HIV and hepatitis C virus (HCV) risk behaviors and prevalent infection among people who inject drugs (PWID) in New York City (NYC). METHODS PWID in NYC were sampled using respondent-driven sampling in 2005, 2009, and 2012 (serial cross sections) for the Centers for Disease Control and Prevention-sponsored National HIV Behavioral Surveillance study. Participants were interviewed about their current (≤12 months) risk behaviors and tested for HIV and HCV. The crude and adjusted risk ratio (RR) and 95% confidence interval (95% CI) for linear time trends were estimated using generalized estimating equations regression with a modified Poisson model. RESULTS The sample comprised 500, 514, and 525 participants in 2005, 2009, and 2012, respectively. Significant (P < 0.05) linear trends in risk behaviors included a decline in unsafe syringe sources (60.8%, 31.3%, 46.7%; RR = 0.86, 95% CI: 0.81 to 0.92), an increase in all syringes from syringe exchanges or pharmacies (35.4%, 67.5%, 50.3%; RR = 1.15, 95% CI: 1.09 to 1.22), and an increase in condomless vaginal or anal sex (53.6%, 71.2%, 70.3%; RR = 1.14, 95% CI: 1.09 to 1.19). Receptive syringe sharing (21.4%, 27.0%, 25.1%), sharing drug preparation equipment (45.4%, 43.4%, 46.7%), and having ≥2 sex partners (51.2%, 44.0%, 50.7%) were stable. Although HIV seroprevalence declined (18.1%, 12.5%, 12.2%), HCV seroprevalence was high (68.2%, 75.8%, 67.1%). In multivariate analysis, adjusting for sample characteristics significantly associated with time, linear time trends remained significant, and the decline in HIV seroprevalence gained significance (adjusted RR = 0.76, 95% CI: 0.64 to 0.91, P = 0.003). CONCLUSIONS This trend analysis suggests declining HIV prevalence among NYC PWID. However, HCV seroprevalence was high and risk behaviors were considerable. Longitudinal surveillance of HIV and HCV risk behaviors and infections is needed to monitor trends and for ongoing data-informed prevention among PWID.

Abstract
The National HIV Behavioral Surveillance system was designed to monitor risk factors for HIV infection and HIV prevalence among individuals at higher risk for HIV infection, that is, sexually active men who have sex with men who attend venues, persons who recently injected drugs, and heterosexuals of low socioeconomic status living in urban areas. These groups were selected as priorities for behavioral surveillance because they represent the major HIV transmission routes and the populations with the highest HIV burden. Accurate data on the behaviors in these populations are critical for understanding trends in HIV infections and planning and evaluating effective HIV prevention activities. The articles in this supplement illustrate how National HIV Behavioral Surveillance data can be used to assess HIV risk behaviors, prevalence, and service utilization of the populations most affected by HIV in the United States and guide local and national high-impact prevention strategies to meet national HIV prevention goals.

Abstract
New combination human acquired deficiency (HIV) prevention strategies that include biomedical and primary prevention approaches add complexity to the task of measuring sexual risk. Latent transition models are beneficial for understanding complex phenomena; therefore, we trialed the application of latent class and latent transition models to HIV surveillance data. Our aims were to identify sexual risk states and model individuals' transitions between states. A total of 4,685 HIV-negative men who have sex with men (MSM) completed behavioral questionnaires alongside tests for HIV and sexually transmissible infections at one of 2 Melbourne, Victoria, Australia, general practices (2007-2013). We found 4 distinct classes of sexual risk, which we labeled "monogamous" (n = 1,224), "risk minimizer" (n = 1,443), "risk potential" (n = 1,335), and "risk taker" (n = 683). A positive syphilis, gonorrhea, or chlamydia test was significantly associated with class membership. Among a subset of 516 MSM who had at least 3 clinic visits, there was general stability across risk classes; MSM had on average a 0.70 (i.e., 70%) probability of remaining in the same class between visits 1 and 2 and between visits 2 and 3. Monogamous MSM were one exception; the probability of remaining in the monogamous class was 0.51 between visits 1 and 2. Latent transition analyses identified unobserved risk patterns in surveillance data, characterized high-risk MSM, and quantified transitions over time.

Abstract
BACKGROUND Among people who inject drugs (PWID) in the United States, those who initiated drug injection in Puerto Rico (immigrant Puerto Rican PWID) engage in more injection and sexual risk behaviors, and have higher HIV incidence than non-Hispanic whites. OBJECTIVE Understand the persistence of these HIV behaviors. METHODS In a cross-sectional study conducted in New York City (NYC) in 2012 (National HIV Behavioral Surveillance), PWID aged ≥18 years were recruited using Respondent-Driven Sampling, interviewed, and tested for HIV. Participants were categorized into 5 different groups: (1) US-born non-Hispanic PWID, (2) US-born Puerto Rican PWID, (3) recent immigrant Puerto Rican PWID (≤3 years in NYC), (4) medium-term immigrant Puerto Rican PWID (>3 and ≤10 years in NYC), and (5) long-term immigrant Puerto Rican PWID (>10 years in NYC). We examined the relationship between time since migrating on sexual and injection risk behaviors among immigrant Puerto Rican PWID, compared with U.S.-born Puerto Rican PWID and US-born non-Hispanic PWID. Adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) were estimated using logistic regression. RESULTS A total of 481 PWID were recruited. In adjusted analyses using US-born non-Hispanic PWID as the comparison group, syringe sharing was significantly more likely among medium-term immigrants; and unprotected sex with casual partners was more likely among recent and long-term immigrants. CONCLUSIONS The risk-acculturation process for immigrant Puerto Rican PWID may be nonlinear and may not necessarily lead to risk reduction over time. Research is needed to better understand this process.

Abstract
Community sexual bridging may influence the socio-geographic distribution of heterosexually transmitted HIV. In a cross-sectional study, heterosexual adults at high-risk of HIV were recruited in New York City (NYC) in 2010 for the Centers for Disease Control and Prevention-sponsored National HIV Behavioral Surveillance system. Eligible participants were interviewed about their HIV risk behaviors and sexual partnerships and tested for HIV. Social network analysis of the geographic location of participants' recent sexual partnerships was used to calculate three sexual bridging measures (non-redundant ties, flow-betweenness and walk-betweenness) for NYC communities (defined as United Hospital Fund neighborhoods), which were plotted against HIV prevalence in each community. The analysis sample comprised 494 participants and 1534 sexual partnerships. Participants were 60.1 % male, 79.6 % non-Hispanic black and 19.6 % Hispanic race/ethnicity; the median age was 40 years (IQR 24-50); 37.7 % had ever been homeless (past 12 months); 16.6 % had ever injected drugs; in the past 12 months 76.7 % used non-injection drugs and 90.1 % engaged in condomless vaginal or anal sex; 9.6 % tested HIV positive (of 481 with positive/negative results). Sexual partnerships were located in 33 (78.6 %) of 42 NYC communities, including 13 "high HIV-spread communities", 7 "hidden bridging communities", 0 "contained high HIV prevalence communities", and 13 "latent HIV bridging communities". Compared with latent HIV bridging communities, the population racial/ethnic composition was more likely (p < 0.0001) to be black or Hispanic in high HIV-spread communities and to be black in hidden bridging communities. High HIV-spread and hidden bridging communities may facilitate the maintenance and spread of heterosexually transmitted HIV in black and Hispanic populations in NYC.

Abstract
PURPOSE The aim of this study was to assess the exposure to and impact of the It's Never Just HIV mass media campaign aimed at HIV negative men who have sex with men (MSM) in New York City. METHODS Questions about the campaign were included in the local questionnaire of the Centers for Disease Control and Prevention (CDC)-sponsored National HIV Behavioral Surveillance (NHBS) study of MSM in NYC conducted in 2011. Participants in this cross-sectional study were recruited using venue-based sampling. RESULTS Among 447 NYC National HIV Behavioral Surveillance study participants who self-reported HIV negative or unknown status and answered questions about the NYC Department of Health and Mental Hygiene's It's Never Just HIV campaign, more than one-third (n = 173, 38.7%) reported having seen the campaign. Latinos (34.8%) and blacks (34.4%) were less likely to report seeing the campaign compared to whites (47.7%). Most of those who reported seeing the campaign saw it on the subway (80.1%). Only 9.4% of those who saw the campaign reported having changed their sexual or health behaviors in response to the campaign. CONCLUSIONS These data suggest that thousands of HIV-uninfected MSM in NYC have been reached by the campaign and recalled its message.

Abstract
In most countries in the world outside of sub-Saharan Africa, HIV is largely concentrated in sub-populations whose behavior puts them at higher risk of contracting and transmitting HIV, such as people who inject drugs, sex workers and men who have sex with men. Estimating the size of these sub-populations is important for assessing overall HIV prevalence and designing effective interventions. We present a Bayesian hierarchical model for estimating the sizes of local and national HIV key affected populations. The model incorporates multiple commonly used data sources including mapping data, surveys, interventions, capture-recapture data, estimates or guesstimates from organizations, and expert opinion. The proposed model is used to estimate the numbers of people who inject drugs in Bangladesh.

Abstract
The extent of gay-related discrimination in New York City (NYC) and the demographic and behavioral factors correlated with experiences of gay-related discrimination are not well understood. The Centers for Disease Control and Prevention-sponsored National HIV Behavioral Surveillance System, a cross-sectional study, was conducted in NYC in 2011. Men who have sex with men were venue-sampled, interviewed, and offered HIV testing. Frequencies of types of gay-related discrimination experienced in the past 12 months were calculated. Associations between types of discrimination and demographic and HIV risk variables were examined through the estimation of prevalence ratios (PRs) and 95% confidence intervals (CIs). More than half (53.2%) of all study participants reported having experienced any gay-related discrimination in the past 12 months; 45.0% reported that they had been called names or insulted; 23.6% reported receiving poorer services than other people in restaurants, stores, other businesses, or agencies; 22.0% reported being treated unfairly at work or school; 15.1% reported being physically attacked or injured; and 6.7% reported being denied or given lower quality health care. HIV-positive status (adjusted PR [aPR] = 2.9; 95% CI = 1.5, 5.6) and drug use in the past 12 months (aPR = 0.3; 95% CI = 0.1, 0.7) were independently associated with reports of having been denied or given lower quality health care. High rates of reported gay-related discrimination suggest that greater efforts are needed to reduce gay-related discrimination in affected communities. Future research is needed to better understand the extent of gay-related discrimination in NYC, particularly with regard to the relationship between HIV status and health care access.

Abstract
BACKGROUND Compared to female IDUs, the correlates of receiving money, drugs, or other things in exchange for sex ("selling sex") among male IDUs are not well understood. METHODS In 2012, IDUs were sampled in New York City for the National HIV Behavioral Surveillance cross-sectional study using respondent driven sampling. Analyses were limited to male participants. Logistic regression was used to calculate crude and adjusted odds ratios (aOR) and 95% confidence intervals (95% CI) to determine the correlates of selling sex to (1) men and (2) women in the past 12 months. RESULTS Of 394 males, 35 (8.9%) sold sex to men and 66 (16.8%) sold sex to women. Correlates of selling sex to men included bisexual/gay identity (aOR: 31.0; 95% CI: 8.1, 119.1), Bronx residence (vs. Manhattan) (aOR: 38.1; 95% CI: 6.2, 235.5), and in the past 12 months, being homeless (aOR: 9.9; 95% CI: 2.0, 49.6), ≥3 sex partners (aOR: 26.2; 95% CI: 4.7, 147.6), non-injection cocaine use (aOR: 5.4; 95% CI: 1.6, 18.2), and injecting methamphetamine (aOR: 36.9; 95% CI: 5.7, 240.0). Correlates of selling sex to women included, in the past 12 months, ≥3 sex partners (aOR: 14.6; 95% CI: 6.6, 31.9), binge drinking at least once a week (aOR: 3.1; 95% CI: 1.6, 6.1), non-injection crack use (aOR: 3.3; 95% CI: 1.6, 6.7), most frequently injected "speedball" (vs. heroin) (aOR: 2.1; 95% CI: 1.1, 4.2), and receptively shared syringes (aOR: 2.4; 95%CI: 1.2, 4.8). CONCLUSIONS Among male IDUs, those who sold sex had more sex partners, which may facilitate the sexual spread of HIV among IDUs and to non-IDU male and female sex partners. HIV prevention interventions aimed at male IDUs who sell sex should consider both their sexual and parenteral risks and the greater risk of engaging in exchange sex associated with the use of injection and non-injection stimulant drugs.

Abstract
BACKGROUND Our goal was to examine whether community-based behavioral surveys can augment data collected for the National HIV Behavioral Surveillance System (NHBS) among men who have sex with men (MSM) in San Francisco. METHODS We compared estimates of sexual risk behaviors among MSM using data from two cycles of NHBS (2004 and 2008) and outreach surveys conducted by STOP AIDS Project (SAP) during the same years. We compared estimates of unprotected anal intercourse (UAI) and other indicators to assess concordance of estimates across methodologies. RESULTS Of the 3248 interviews conducted, the NHBS sample included more nonwhite and older MSM, more self-reported HIV positive, and less sexually active men than the SAP sample. Estimates of UAI in the last 6 months were slightly higher in the NHBS survey than in the SAP surveys (2004: 40% vs. 36%, P = 0.03; 2008: 44% vs. 38%, P = 0.08). In 2008, where respondent-partner HIV-discordant status could be measured, estimates of UAI with a potentially discordant partner were similar (12% vs. 12%, P = 0.87). Also, the NHBS and SAP surveys observed similar estimates of UAI by high-risk positioning with potentially discordant partners (HIV-positive men reporting insertive UAI with a potentially HIV-negative partner: 13% vs. 11%, P = 0.45; HIV-negative men reporting receptive UAI with a potentially HIV-positive person: 5% vs. 4%, P = 0.85). CONCLUSIONS Behavioral estimates drawn from convenience sampling methods can provide informative surveillance estimates of key behavioral indictors that can augment data from more rigorous national HIV behavioral surveillance surveys.

Abstract
BACKGROUND The challenge of identifying and recruiting U.S. women at elevated risk for HIV acquisition impedes prevention studies and services. HIV Prevention Trials Network (HPTN) 064 was a U.S. multisite, longitudinal cohort study designed to estimate HIV incidence among women living in communities with prevalent HIV and poverty. Venue-based sampling (VBS) methodologies and participant and venue characteristics are described. METHODS Eligible women were recruited from 10 U.S. communities with prevalent HIV and poverty using VBS. Participant eligibility criteria included age 18-44 years, residing in a designated census tract/zip code, and self-report of at least one high-risk personal and/or male sexual partner characteristic associated with HIV acquisition (e.g., incarceration history). Ethnography was conducted to finalize recruitment areas and venues. RESULTS Eight thousand twenty-nine women were screened and 2,099 women were enrolled (88% black, median age 29 years) over 14 months. The majority of participants were recruited from outdoor venues (58%), retail spaces (18%), and social service organizations (13%). The proportion of women recruited per venue category varied by site. Most participants (73%) had both individual and partner characteristics that qualified them for the study; 14% were eligible based on partner risk only. CONCLUSION VBS is a feasible and effective approach to rapidly recruit a population of women at enhanced risk for HIV in the United States. Such a recruitment approach is needed in order to engage women most at risk and requires strong community engagement.

Abstract
We examined differences in sample demographics across cycles of the National HIV Behavioral Surveillance project, that examines HIV risk behaviors among men who have sex with men (MSM), injection drug users (IDU), and heterosexuals living in areas of high HIV prevalence (HET). MSM were recruited through venue-based sampling, and IDU and HET through respondent driven sampling (RDS). RDS data were weighted to account for sampling bias. We compared crude prevalence estimates from MSM1 (2004) to those from MSM2 (2008) for demographic factors known to influence risky sexual and drug-use behaviors. We compared crude and adjusted prevalence estimates for IDU1 (2005) and IDU2 (2009) and HET1 (2006) and HET2 (2010). In the MSM cycle, we found differences in age, and the proportions seeking medical care and reporting a recent arrest. There were no differences in the comparison of crude and weighted estimates for the RDS collected samples, nor were there differences comparing HET1 and HET2 weighted estimates. IDU2 recruited a larger proportion of males, and had a higher percent who graduated from high school and who reported recent medical care and a previous HIV test. Differences across MSM cycles may be related to differences in venues identified for each cycle. Differences in the IDU cycles may be due to an effort on our part to increase the racial/ethnic and drug-use diversity of the sample in IDU2. Our findings show the importance of formative work for both venue-based and RDS samples to increase understanding of the dimensions that affect social networks and the dynamics of populations in space and time. With familiarity of the target population, we believe that both venue-based and RDS recruitment approaches for NHBS work well and can be used to evaluate changes in risky sexual and drug use behaviors and in HIV testing behaviors.

Abstract
This study examined trends in HIV prevalence and HIV-related risk behaviors from 2004 through 2011 among men who have sex with men (MSM) in New York City. MSM were venue-sampled, interviewed, and offered HIV testing in serial cross-sectional studies. Significant differences in overall time trends were determined using the Spearman rank correlation and logistic regression models. There were 457 (2004-2005), 550 (2008), and 510 (2011) participants in each study round. There was no significant trend in HIV prevalence over time, and past 12 month unprotected anal intercourse remained steady. However, drug use and number of sex partners declined. Among those who did not self-report being HIV positive, the percentage that tested for HIV in the past 12 months increased. The results from this study suggest that from 2004 through 2011 more MSM in New York City are being tested for HIV and have declining drug use and fewer sex partners.

Abstract
The epidemiology of HIV in urban centers of the United States such as the District of Columbia (DC) is dynamic with rates of new HIV and AIDS diagnoses as well as risk factors elevated. Correlates of HIV among heterosexual women extend beyond traditional, individual risk factors to structural factors. The purpose of this study was to compare proportions of HIV and correlates of HIV among women participating in National HIV behavioral surveillance (NHBS) system in 2006-7 (NHBS Cycle 1) and 2010 (NHBS Cycle 2). Analysis of 677 female participants at elevated risk for HIV revealed high prevalence of individual-level HIV-associated risk factors (e.g., sexual behavior) and socio-structural associated risk factors (e.g., homelessness, incarceration, lack of health insurance). While a greater proportion of women were HIV-infected in Cycle 2, after controlling for the distribution of demographic characteristics to adjust for a change in eligibility criteria, the pooled sample did not reveal a significantly increased proportion of HIV-infected women in Cycle 2. Homelessness and condom use were associated with greater relative odds of HIV after adjustment for confounders, and non-injection drug use was associated with reduced odds. Findings inform our understanding of the continuing HIV epidemic in DC and support development of effective interventions to slow the epidemic among women in DC and similar urban centers.

Abstract
The National HIV Behavioral Surveillance system (NHBS) was designed to monitor HIV prevalence and risk factors for infection among higher-risk individuals, i.e., sexually active men who have sex with men who attend venues, injection drug users who injected in the past 12 months, and heterosexuals living in low socioeconomic urban areas. These groups were selected as priorities for behavioral surveillance since they represent the major HIV transmission routes and the populations with the highest HIV burden. NHBS contributes to the nation's program of HIV surveillance by being the only multi-site population-based system that provides estimates on key HIV prevention measures among high-risk HIV-negative individuals, HIV-positive individuals unaware of their infection, and HIV-positive individuals aware of their infection who are in and out of care. Accurate and precise data on the behaviors in these populations are critical for tracking the epidemic, planning effective responses, and monitoring and evaluating those responses. Reports in this supplement illustrate the uses of NHBS data at the national and local level and reflect ongoing efforts to improve the system and remains essential for characterizing and monitoring the burden of HIV infection and sexual and behavioral risks.

Abstract
Understanding factors associated with recent HIV testing among men who have sex with men (MSM) is important for designing interventions to increase testing rates and link cases to care. A cross-sectional study of MSM was conducted in NYC in 2011 using venue-based sampling. Associations between HIV testing in the past 12 months and relevant variables were examined through the estimation of prevalence ratios (PR) and 95 % confidence intervals (CI). Of 448 participants, 107 (23.9 %) had not been tested in the past 12 months. Factors independently associated with not testing in the previous 12 months were: lack of a visit to a healthcare provider in the past 12 months (aPR: 2.5; 95 % CI: 1.9, 3.2); age ≥30 (adjusted PR: 1.9; 95 % CI: 1.4, 2.7); not having completed a bachelor's degree (aPR: 1.6; 95 % CI: 1.0, 2.4); and non-gay sexual identity (aPR: 1.4; 95 % CI: 1.0, 1.8); such MSM may be less aware of the need for frequent HIV testing.

Abstract
Following latent class analysis (LCA) approach we examined patterns of HIV risk using two related domains of behavior: drug use, and sexual activity among 523 injection drug users (IDUs) recruited into the 2009 National HIV behavioral surveillance system. Using posterior probability of endorsing six drug and sexual items, we identified three distinct classes representing underlying HIV risk. Forty percent of our participants were at highest risk, 25 % at medium risk, and 35 % at lowest risk for HIV infection. Compared to the Lowest-risk class members, the Highest-risk class members had riskier drug and sexual behaviors and had higher prevalence of HIV cases (6 vs. 4 %). This analysis underscores the merit of LCA to empirically identify risk patterns using multiple indicators and our results show HIV risk varies among IDUs as their drug and sexual behaviors. Tailored and targeted prevention and treatment interventions for the dual risk pattern are required rather than for drug or sexual risk in silos.

Abstract
Repeated behavioural surveillance should sample all epidemiologically relevant subgroups to provide a complete picture of trends in HIV risk behaviours. Web-based recruitment has been mooted but little empirical data exist on country experiences. We describe who is omitted from three rounds of a conventional offline-only surveillance programme among men who have sex with men (MSM) 2006-2011, but recruited subsequently on Internet dating sites, and the implications of this for understanding trends. The latter were younger, less gay identified and less gay community attached. Importantly, they reported different partnering patterns, lower condom use with casual and fuckbuddy-type male partners, and lower rates of HIV testing, compared to MSM routinely captured in offline surveillance. The replacement of offline socio-sexual activity by the Internet among many MSM means that current venue-based surveillance systems may underestimate risk behaviours, overlook trends among unsampled online MSM, and misinterpret trends observed in sampled MSM due to "sample drift" of most-at-risk MSM.

Abstract
Inconsistent findings on the relationship of sex partner concurrency to infection with HIV and other sexually transmitted diseases (STDs) may result from differences in how sex partner concurrency is conceptualized. We examine the relationship of reciprocal sex partner concurrency (RSPC) to diagnosed STDs among heterosexuals. Heterosexually active adults (N = 717) were recruited for a cross-sectional study using respondent-driven sampling (RDS) from high-HIV-risk areas in New York City (NYC, 2006-2007) and interviewed about their sexual risk behaviors, number of sex partners, last sex partners, and STD diagnoses (prior 12 months). RSPC was when both the participant and her/his last sex partner had sex with other people during their sexual relationship. Odds ratios (OR), adjusted odds ratios (aOR), and 95 % confidence intervals (95%CI) were estimated by logistic regression. The sample was 52.4 % female, 74.3 % Black; median age was 40 years. RSPC was reported by 40.7 % and any STD diagnoses by 23.4 %. Any STDs was reported by 31.5 % of those reporting RSPC vs. 17.9 % of those who did not (OR = 2.11, 95%CI = 1.49-3.0). Any STDs was independently associated with RSPC (aOR = 1.54, 95%CI = 1.02-2.32), female gender (aOR = 2.15, 95%CI = 1.43-3.23), having more than three sex partners (aOR = 1.72, 95%CI = 1.13-2.63), and unprotected anal sex (aOR = 1.65, 95%CI = 1.12-2.42). Heterosexuals in high-HIV-risk neighborhoods in sexual partnerships that involve RSPC are at greater risk of STDs and, potentially, HIV. RSPC, in addition to sexual risk behaviors and the number of sex partners, may facilitate the heterosexual spread of HIV through STD cofactors and linkage into larger STD/HIV sexual transmission networks.

Abstract
BACKGROUND Black women are disproportionally affected by human immunodeficiency virus (HIV). This study investigates factors associated with newly identified HIV infection among previously self-reported HIV negative or unknown status black women living in high risk areas (HRAs) of New York City (NYC). METHODS Heterosexuals residing in or socially connected to NYC HRAs were recruited using respondent driven sampling for participation in the United States Centers for Disease Control-sponsored National HIV Behavioral Surveillance System in 2010. Eligible individuals were interviewed and offered an HIV test. The analysis reported here focused on black women with valid HIV results who did not report being HIV positive, and examined factors related to HIV infection in this group. RESULTS Of 153 black women who did not report being HIV positive at enrollment, 15 (9.8%) tested HIV positive. Age ≥40 years, ever injected drugs, and in the last 12 months had unprotected vaginal sex, exchange sex, last sex partner used crack, non-injection crack use, and non-injection heroin use were significantly associated with HIV infection (p<0.05). Only ever injected drugs (prevalence ratio: 5.1; 95% confidence interval: 2.0, 12.9) was retained in the final model. CONCLUSIONS Black women who had reported being either HIV negative or unaware of their serostatus had high HIV prevalence. Efforts to identify and treat HIV positive black women in HRAs should target those with a history of injection drug use. Frequent testing for HIV should be promoted in HRAs.

Abstract
Several assumptions determine whether respondent-driven sampling (RDS) is an appropriate sampling method to use with a particular group, including the population being recruited must know one another as members of the group (i.e., injection drug users [IDUs] must know each other as IDUs) and be networked and that the sample size is small relative to the overall size of the group. To assess these three assumptions, we analyzed city-specific data collected using RDS through the US National HIV Behavioral Surveillance System among IDUs in 23 cities. Overall, 5% of non-seed participants reported that their recruiter was “a stranger.” 20 cities with multiple field sites had ≥1 cross-recruitment, a proxy for linked networks. Sample sizes were small in relation to the IDU population size (median = 2.3%; range: 0.6%- 8.0%). Researchers must evaluate whether these three assumptions were met to justify the basis for using RDS to sample specific populations.

Abstract
In a cross-sectional study, MSM aged ≥18 years were venue-sampled in New York City in 2008, interviewed, and tested for HIV using oral fluids. Participants who reported testing HIV negative at their last test in the previous 24 months were analyzed (n = 287 of 550 sampled). Those testing positive at the interview were defined as recently infected. HIV incidence was estimated using person-time at-risk methods and correlates of recent infection using proportional hazards regression. Thirty-two (11.1%) were recently infected. HIV incidence was 5.67/100 person-years at-risk. Independent correlates included: study recruitment in parks vs. bars, and in other venues vs. bars; black vs. non-black race/ethnicity; and reporting a last sex partner with a positive or unknown vs. negative HIV status. When assay-based methods are not feasible, cross-sectional HIV test results and self-reported HIV testing history and risk factor data can be used to estimate HIV incidence and the correlates of recent infection.

Abstract
Men who have sex with transgender women are a potentially high-risk population for HIV and other sexually transmitted infections (STIs). We administered structured quantitative surveys to 174 men whose primary partner was a transgender woman. We assessed men's demographic characteristics, sexual behaviors, substance use, and social-psychological factors, including condom use self-efficacy and depression. Overall, 19% reported being HIV-positive (8% had been diagnosed with AIDS), 11% had at least one other STI during the past year, and 16% reported being in a HIV serodiscordant relationship with their primary partner. In the past 3 months, 40% had unprotected anal or vaginal sex with any partner. In multivariate analysis, significant correlates of having unprotected sex included younger age, concurrent partnerships, alcohol intoxication, and low condom use self-efficacy; depression was marginally associated with having unprotected sex. Interventions are needed to reduce risk for HIV and other STIs among men who have sex with transgender women. Prevention programs for these men should build condom use self-efficacy and address the contributions of alcohol intoxication, concurrent sex partnerships, and depression to sexual risk behavior.

Abstract
OBJECTIVES We used existing data systems to examine sexually transmitted disease (STD) and HIV/AIDS diagnosis rates and explore potential county-level associations between HIV/AIDS diagnosis rates and socioeconomic disadvantage. METHODS Using South Carolina county data, we constructed multivariate ring maps to spatially visualize syphilis, gonorrhea, chlamydia, and HIV/AIDS diagnosis rates; gender- and race-specific HIV/AIDS diagnosis rates; and three measures of socioeconomic disadvantage-an unemployment index, a poverty index, and the Townsend index of social deprivation. Statistical analyses were performed to quantitatively assess potential county-level associations between HIV/AIDS diagnosis rates and each of the three indexes of socioeconomic disadvantage. RESULTS Ring maps revealed substantial spatial association in STD and HIV/AIDS diagnosis rates and highlighted large gender and racial disparities in HIV/AIDS across the state. The mean county-level HIV/AIDS diagnosis rate (per 100,000 population) was 24.2 for males vs. 11.2 for females, and 34.8 for African Americans vs. 5.2 for white people. In addition, ring map visualization suggested a county-level association between HIV/AIDS diagnosis rates and socioeconomic disadvantage. Significant positive bivariate relationships were found between HIV/AIDS rate categories and each increase in poverty index category (odds ratio [OR] = 2.03; p=0.006), as well as each increase in Townsend index of social deprivation category (OR=4.98; p<0.001). A multivariate ordered logistic regression model in which all three socioeconomic disadvantage indexes were included showed a significant positive association between HIV/AIDS and Townsend index categories (adjusted OR=6.10; p<0.001). CONCLUSIONS Ring maps graphically depicted the spatial coincidence of STD and HIV/AIDS and revealed large gender and racial disparities in HIV/AIDS across South Carolina counties. This spatial visualization method used existing data systems to highlight the importance of social determinants of health in program planning and decision-making processes.

Abstract
Background These data were collected as part of the National HIV Behavioral Surveillance (NHBS) study. NHBS is a cross-sectional study to investigate HIV behavioral risks among core risk groups in 21 U.S. cities with the highest HIV/AIDS prevalence. This analysis examines data from the NHBS data collection cycle with IDU conducted in New York City in 2009. We explored how the recency of migration from Puerto Rico (PR) to New York City (NYC) impacts both syringe sharing and unprotected sex among injection drug users (IDU) currently living in NYC. Methods We used a mixed-methods approach to examine differences in risk between US-born IDU, PR IDU who migrated to NYC more than three years ago (non-recent migrants), and PR IDU who migrated in the last three years (recent migrants). Respondent-driven sampling (RDS) was used to recruit the sample (n = 514). In addition, qualitative individual and group interviews with recent PR migrants (n = 12) and community experts (n = 2) allowed for an in-depth exploration of the IDU migration process and the material and cultural factors behind continued risk behaviors in NYC. Results In multiple logistic regression controlling for confounding factors, recent migrants were significantly more likely to report unprotected sexual intercourse with casual or exchange partners (adjusted odds ratio [AOR]: 2.81; 95% confidence intervals [CI]: 1.37-5.76) and receptive syringe sharing (AOR = 2.44; 95% CI: 1.20-4.97) in the past year, compared to US-born IDU. HIV and HCV seroprevalence were highest among non-recent migrants. Qualitative results showed that risky injection practices are partly based on cultural norms acquired while injecting drugs in Puerto Rico. These same results also illustrate how homelessness influences risky sexual practices. Conclusions Poor material conditions (especially homelessness) may be key in triggering risky sexual practices. Cultural norms (ingrained while using drugs in PR) around injection drug use are perpetuated in their new setting following an almost natural flow. These norms may have a particular stronghold over risky drug injection practices. These results indicate that culturally appropriate HIV and HCV prevention and education services are needed. In addition, homelessness should be addressed to reduce risky sexual practices.

Abstract
The U.S. HIV/AIDS epidemic disproportionately impacts lower-income populations. We conducted a cross-sectional study of heterosexually active adults (N = 1076) in areas with high poverty and HIV/AIDS rates in South Florida in 2007. Using venue-based sampling, anonymous interviews and HIV tests were conducted at randomly selected venues (primarily retail businesses not associated with risk behaviors). The sample's HIV infection rate was 7.1%. Half (52.2%) of the infections were previously undiagnosed. Our findings underscore the impact of social and environmental factors on HIV risk, as well as the need to increase and optimize HIV testing and other prevention services.

Abstract
We assessed trends in behavioral risk for HIV infection among men who have sex with men (MSM). Seattle MSM participated in random digit dial telephone surveys in 2003 (n = 400) and 2006 (n = 400). Fourteen percent in 2003 and 9% in 2006 reported unprotected anal intercourse with a partner of different or unknown HIV status (non-concordant UAI; odds ratio [OR] = 0.7; 95% confidence interval [CI]: 0.5, 1.2). Compared to participants in 2003, participants in 2006 met a greater proportion of their anal sex partners through the Internet (OR = 2.0; 95% CI: 1.2, 3.1). Although the proportion of anal sex partnerships formed online increased between 2003 and 2006, Internet partnerships were not more risky than those initiated elsewhere. While the emergence of the Internet as a venue through which men meet partners demonstrates that sexual risk among MSM remains highly dynamic, our findings suggest that sexual risk behavior among MSM is currently stable.

Abstract
Herpes simplex virus type 2 (HSV-2) has been shown to increase the risk of sexual human immunodeficiency virus (HIV) transmission. A matched case-control design was used to examine the association between HSV-2 and HIV infection among heterosexuals in 'high-risk areas' (HRAs) in New York City (NYC). We identified NYC HRAs using HIV surveillance data on heterosexual-related adult HIV diagnoses and USA census data on household poverty. Heterosexuals who were socially or geographically linked to an HRA were recruited using respondent-driven sampling. HIV prevalence was 8.6% and HSV-2 prevalence was 80.1%. Only 6% of HIV-positives knew they were infected. HIV-positive cases were matched to HIV-negative controls on gender, race/ethnicity and age, and tested for antibody to HSV-2. In a multivariate model, HIV infection was associated with HSV-2 infection (adjusted odds ratio [AOR] = 3.5, 95% confidence interval 1.1-11.7) and non-HSV-related sexually transmitted infection diagnosis in the previous year (AOR = 2.6, 1.1-6.2). Effective approaches to HIV risk reduction for individuals with HSV-2 remain uncertain, and these are urgently needed in high-risk communities where multiple social, behavioural and biological factors that facilitate HIV infection coexist.

Abstract
Sterile syringe access is an important means to reduce HIV risk, but many injection drug users (IDU) who obtain syringes from sterile sources continue to share syringes. We examined the factors associated with continuing syringe sharing in New York City. We recruited 500 active IDU in 2005 through respondent-driven sampling. In multiple logistic regression, not obtaining all syringes in the past year exclusively from sterile sources was associated with increased syringe sharing. Ensuring adequate syringe availability as well as engaging and retaining nonusers and inconsistent users in sterile syringe services may increase sterile syringe access and decrease syringe sharing.

Abstract
The District of Columbia (DC) has among the highest HIV/AIDS rates in the United States, with 3.2% of the population and 7.1% of black men living with HIV/AIDS. The purpose of this study was to examine HIV risk behaviors in a community-based sample of men who have sex with men (MSM) in DC. Data were from the National HIV Behavioral Surveillance system. MSM who were 18 years were recruited via venue-based sampling between July 2008 and December 2008. Behavioral surveys and rapid oral HIV screening with OraQuick ADVANCE ½ (OraSure Technologies, Inc., Bethlehem, PA) with Western blot confirmation on positives were collected. Factors associated with HIV positivity and unprotected anal intercourse were identified. Of 500 MSM, 35.6% were black. Of all men, 14.1% were confirmed HIV positive; 41.8% of these were newly identified HIV positive. Black men (26.0%) were more likely to be HIV positive than white (7.9%) or Latino/Asian/other (6.5%) men (p<0.001). Black men had fewer male sex partners than non-black, fewer had ever engaged in intentional unprotected anal sex, and more used condoms at last anal sex. Black men were less likely to have health insurance, have been tested for HIV, and disclose MSM status to health care providers. Despite significantly higher HIV/AIDS rates, black MSM in DC reported fewer sexual risks than non-black. These findings suggest that among black MSM, the primary risk of HIV infection results from nontraditional sexual risk factors, and may include barriers to disclosing MSM status and HIV testing. There remains a critical need for more information regarding reasons for elevated HIV among black MSM in order to inform prevention programming.

Abstract
More than half a million Americans became newly infected with human immunodeficiency virus (HIV) in the first decade of the new millennium. The domestic epidemic has had the heaviest impact on men who have sex with men and persons from racial and ethnic minority populations, particularly black persons. For example, black men who have sex with men represent <1% of the US population but 25% of new HIV infections, according to Centers for Disease Control and Prevention estimates published in 2008. Although black and Hispanic women constitute 24% of all US women, they accounted for 82% of HIV infections among women in 2005, according to data from 33 states with confidential name-based reporting. There is a nearly 23-fold higher rate of AIDS diagnoses among black women (45.5 diagnoses per 100,000 women) and a nearly 6-fold higher rate among Hispanic women (11.2 diagnoses per 100,000 women), compared with the rate among white women (2.0 diagnoses per 100,000 women). Investigators from the HIV Prevention Trials Network, a National Institutes of Health-sponsored collaborative clinical trials group, have crafted a domestic research agenda with community input. Two new domestic studies are in progress (2009), and a community-based clinical trial feasibility effort is in development (2010 start date). These studies focus on outreach, testing, and treatment of infected persons as a backbone for prevention of HIV infection. Reaching persons not receiving health messages and services with novel approaches to both prevention and treatment is an essential priority for control of HIV infection in the United States; our research is designed to guide the best approaches and assess the impact of bridging treatment and prevention.

Abstract
OBJECTIVES To identify existing respiratory hygiene risk practices, and guide the development of interventions for improving respiratory hygiene. METHODS We selected a convenience sample of 80 households and 20 schools in two densely populated communities in Bangladesh, one urban and one rural. We observed and recorded respiratory hygiene events with potential to spread viruses such as coughing, sneezing, spitting and nasal cleaning using a standardized assessment tool. RESULTS In 907 (81%) of 1122 observed events, households' participants coughed or sneezed into the air (i.e. uncovered), 119 (11%) into their hands and 83 (7%) into their clothing. Twenty-two per cent of women covered their coughs and sneezes compared to 13% of men (OR 2.6, 95% CI 1.6-4.3). Twenty-seven per cent of persons living in households with a reported monthly income of >72.6 US$ covered their coughs or sneezes compared to 13% of persons living in households with lower income (OR 3.2, 95% CI 1.6-6.2). In 956 (85%) of 1126 events, school participants coughed or sneezed into the air and 142 (13%) into their hands. Twenty-seven per cent of coughs/sneezes in rural schools were covered compared to 10% of coughs/sneezes in urban schools (OR 2.3, 95% CI 1.5-3.6). Hand washing was never observed after participants coughed or sneezed into their hands. CONCLUSION There is an urgent need to develop culturally appropriate, cost-effective and scalable interventions to improve respiratory hygiene practices and to assess their effectiveness in reducing respiratory pathogen transmission.

Abstract
BACKGROUND HIV testing is an important HIV prevention strategy, yet heterosexuals at high risk do not test as frequently as other groups. We examined the association of past year HIV testing and encounters with institutional settings where the Centers for Disease Control and Prevention recommends annual testing for high-risk heterosexuals. METHODS We recruited high-risk heterosexuals in New York City in 2006 to 2007 through respondent-driven sampling. Respondents were asked the date of their most recent HIV test and any potential encounters with 4 testing settings (homeless shelters, jails/prisons, drug treatment programs, and health care providers). Analyses were stratified by gender. RESULTS Of the 846 respondents, only 31% of men and 35% of women had a past year HIV test, but over 90% encountered at least one testing setting. HIV seroprevalence was 8%. In multiple logistic regression, recent HIV testing was significantly associated with recent encounters with homeless shelters and jails/prisons for men, and encounters with health care providers for both men and women. CONCLUSIONS HIV testing was low overall but higher for those with exposures to potential routine testing settings. Further expansion of testing in these settings would likely increase testing rates and may decrease new HIV infections among high-risk heterosexuals.

Abstract
We conducted a respondent-driven sampling survey (N = 215) to characterize correlates of risk for HIV infection among gay and bisexual men in Kampala, Uganda. We used RDSAT software to produce population estimates for measures and created exportable weights for multivariable analysis. Overall, 60.5% of gay/bi men identify as gay and 39.5% as bisexual; 91.6% are Ugandans. Unprotected receptive anal intercourse (URAI) was associated with identifying as gay, being younger and having had an HIV test in the past 6 months. Perceptions of being low risk to acquire or transmit HIV infection were paradoxically associated with higher likelihood of URAI. Programs to address risk of HIV infection among gay and bisexual men in Kampala need to address perceptions of risk among gay identified men.

Abstract
OBJECTIVES Washington, District of Columbia has the highest HIV/AIDS rate in the United States, with heterosexual transmission a leading mode of acquisition and African-American women disproportionately affected. The purpose of this study was to examine risk factors driving the emergence of the local epidemic using National HIV Behavioral Surveillance data from the District of Columbia. DESIGN The design of the study is cross-sectional. METHODS Individuals at high risk for HIV based on connection to areas with elevated AIDS and poverty were collected from December 2006 to October 2007. Analyses characterized participants from a respondent-driven, nonclinic-based sample; factors associated with preliminary HIV positivity were assessed with logistic regression. RESULTS Of 750 participants, 61.4% were more than 30 years of age, 92.3% African-American, and 60.0% with an annual household income of less than $10 000; 5.2% (95% confidence interval, 2.9-7.2%) screened HIV positive; women were more likely to screen positive than men (6.3 versus 3.9%). Of those, 47.4% (95% confidence interval, 30.9-78.7%) did not know their status prior to the study. Last vaginal sex was unprotected for 71.2% of respondents; 44.9% reported concurrent sex partners, and 45.9% suspected concurrency in their partners. Correlates of screening HIV positive were identified. CONCLUSION This study suggests that a generalized heterosexual HIV epidemic among African-Americans in communities at risk may be emerging in the nation's capital alongside concentrated epidemics among men who have sex with men and injecting drug users. Innovation of prevention strategies is necessary in order to slow the epidemic in District of Columbia.

Abstract
The National Human Immunodeficiency Virus (HIV) Behavioral Surveillance System (NHBS) is the Centers for Disease Control and Prevention's (CDC's) newest system for measuring HIV risk behaviors among three adult populations at highest risk for HIV infection in the U.S.: men who have sex with men, injecting drug users, and heterosexuals at risk of HIV infection. The system is implemented by state and local health departments in designated metropolitan statistical areas with the highest HIV/acquired immunodeficiency syndrome (AIDS) prevalence in the U.S. Prior to implementing the behavioral surveillance survey, project sites conduct a series of formative research activities. The data collected during this preparatory phase provide contextual information about HIV risk behaviors within the study population of interest and help project sites make decisions about field operations and other logistical issues. This article describes the activities undertaken in preparation for the first round of NHBS (2003-2007) and how those activities enhanced data collection for each behavioral surveillance cycle.

Abstract
In the US, federal and state behavioral surveillance systems routinely monitor self-reported sexual behavior and Papanicolaou (Pap) test use to identify high-risk populations, trends, and disparities and to guide and evaluate interventions for cervical cancer prevention and control. Clinical uptake of human papillomavirus (HPV) vaccination and testing necessitates the expansion of behavioral surveillance systems. Cervical disease is the main focus of HPV-related behavioral surveillance because of greater cancer incidence and mortality relative to other susceptible organs, and the availability of effective technologies for prevention and control. In the current study, a framework is presented for the types of behaviors to monitor, their conceptual and operational definitions, target populations, and evidence supporting the reliability and validity of self-report measures. An overview is also provided of 8 population-based and 2 provider-based data systems that are nationally representative and accessible for behavioral surveillance research. Ongoing surveillance at the national, state, and local level is critical for monitoring the dissemination of HPV technologies and their impact on reducing disparities in the detection of precursor lesions, incidence of invasive cancer, and mortality.

Abstract
China's HIV epidemic may be shifting towards predominantly sexual transmission and emerging data point to potential increases in HIV prevalence among men who have sex with men (MSM). There is particular need to assess the extent of risk behavior among MSM outside of China's most cosmopolitan cities. We conducted a respondent-driven sampling survey (N = 428) to measure HIV seroprevalence and risk behavior among MSM in Jinan, China, the provincial capital of Shandong. HIV prevalence was 0.5% (95% confidence interval [CI] 0.1-1.0). Unprotected anal intercourse (UAI) in the last 6 months (reported by 61.4%) was associated with buying or selling sex to a man in the last 6 months, syphilis infection, multiple partners in the last month, low HIV knowledge and migrant status. No participant had previously tested for HIV. Risk for HIV transmission is widespread among MSM throughout China; basic prevention programs are urgently needed.

Abstract
Although transgender women are acknowledged as a priority population for HIV prevention, there is little knowledge on men who have sex with transgender women (MSTGWs). MSTGWs challenge conventional sexual orientation categories in public health and HIV prevention research, and warrant increased attention from the public health community. This paper used qualitative techniques to analyze how MSTGWs describe their sexual orientation identities, and to explore the correspondence between men's identities and sexual behaviors with transgender women. We conducted in-depth semi-structured individual interviews with 46 MSTGWs in San Francisco. We observed a diversity in the ways participants identified and explained their sexual orientation, and found no consistent patterns between how men described their sexual orientation identity versus their sexual behavior and attraction to transgender women. Findings from this qualitative study question the utility of category-based approaches to HIV prevention with MSTGWs and offer insights into developing HIV interventions for these men.
