Securing public spaces: public willingness to sacrifice convenience and privacy for security at three U.S. public venues

The use of security countermeasures at public venues has escalated dramatically over the past 20 years. We present a study of public venue patrons (N = 1276) examining how public perceptions of efficacy and intrusiveness of four security measures deployed at three different public assembly venues in the U.S. impact planned attendance. Enhanced use of these countermeasures,—Closed-Circuit Televisions (CCTVs), security guards, metal detectors, and bag checks—was evaluated by customers for their effectiveness in ensuring safety against crime and terrorism. We found that the perceived efficacy of the countermeasure in reducing these risks was positively associated with an increased likelihood of customer attendance at the venue. Moreover, customer beliefs about the overall enhancement of venue security and the sense of personal safety offered by these countermeasures also predicted their likelihood of attending. Unexpectedly, the study found that attitudes towards the privacy and convenience aspects of the countermeasures were not significant predictors of venue attendance. Results indicated that both cost and the extent of risk reduction predicted willingness to pay for enhanced security countermeasures. As the cost associated with a security measure increased, customers’ willingness to pay decreased. Conversely, as the perceived risk reduction offered by the security measures increased, customers indicated an increased willingness to pay. We found customers’ beliefs, attitudes, and intentions towards security measures were generally consistent across all three venues, indicating generalizability of findings across a range of public assembly venues in the U.S. Overall, the study provides evidence that customers support security countermeasures and endorse their implementation, which offers valuable insights for venue managers and policymakers aiming to enhance security measures at public assembly venues.

A situational assessment of treatments received for childhood diarrhea in the Federal Republic of Nigeria.

We assess progress towards improved case management of childhood diarrhea in Nigeria over a period of targeted health systems reform from 2013 to 2018. Individual and community data from three Demographic and Health Survey rounds are leveraged in a geospatial model designed for stratified estimation by venue of treatment seeking and State. Our analysis reveals a highly regionalised health system undergoing rapid change. Nationally, there have been substantial increases in the proportion of children under 5 years old with diarrhea receiving the recommended oral rehydration therapy after seeking treatment at either a health clinic (0.57 [0.44-0.69; 95% CI] in 2008; 0.70 [0.54-0.83] in 2018) or chemist/pharmacy (0.28 [0.17-0.42] in 2008; 0.48 [0.31-0.64] in 2018). Yet State-level variations in venue attendance and performance by venue have conspired to hold the overall proportion receiving this potentially life-saving therapy (0.45 [0.35-0.55] in 2018) to well-below ideal coverage levels. High performing states that have demonstrated significant improvements include Kano, Jigawa and Borno, while under-performing states that have suffered declines in coverage include Kaduna and Taraba. The use of antibiotics is not recommended for mild cases of childhood diarrhea yet remains concerningly high nationally (0.27 [0.19-0.36] in 2018) with negligible variation between venues. Antibiotic use rates are particularly high in Enugu, Kaduna, Taraba, Kano, Niger and Kebbi, yet welcome reductions were identified in Jigawa, Adamawa and Osun. These results support the conclusions of previous studies and build the strength of evidence that urgent action is needed throughout the multi-tiered health system to improve the quality and equity of care for common childhood illnesses in Nigeria.

Concerts, bars, parties, and raves: Differential risk for drug use among high school seniors according to venue attendance

Background: Nightlife attendance is an established risk factor for drug use, but studies have not focused on adolescent general population samples or compared risk according to type(s) of venues attended. We examined whether attendance of various types of venues was associated with drug use. Methods: Data were examined from an annual nationally representative survey of high school seniors in the US (2014–2019, N = 11,565). We determined whether past-year attendance of parties, concerts, bars or nightclubs, and raves or dance music events was associated with past-year drug use using mixed-effects logistic regression. Mall and movie attendance were examined as negative controls. Results: Compared to those who reported not attending specific venues, attending parties was associated with higher odds of using alcohol in particular (aOR = 5.03, 95% CI: 3.92–6.44). Attending concerts was associated with higher odds for use of alcohol, cannabis, ecstasy, and nonmedical use of prescription stimulants and opioids. All drugs examined were concentrated among those who attend bars, nightclubs, raves, and dance parties. Rave or dance party attendance was associated with higher odds for use of ecstasy (aOR = 3.71, 95% CI: 2.50–5.50) and methamphetamine (aOR = 4.92, 95% CI: 2.43–9.96) in particular, and bar or nightclub attendance was associated with higher odds of use of cocaine (aOR = 6.49, 95% CI: 4.37–9.63), ecstasy (aOR = 6.49, 95% CI: 4.54–9.27), and methamphetamine (aOR = 5.49, 95% CI: 2.57–11.72) in particular. Attending movies was associated with lower odds for use of cocaine and nonmedical prescription stimulant use. Conclusion: We determined differential risk of drug use depending on types of venues attended by adolescents.

Residential Area Sociodemographic and Breast Cancer Screening Venue Location Built Environmental Features Associated with Women's Use of Closest Venue in Greater Sydney, Australia.

Understanding environmental predictors of women’s use of closest breast screening venue versus other site(s) may assist optimal venue placement. This study assessed relationships between residential-area sociodemographic measures, venue location features, and women’s use of closest versus other venues. Data of 320,672 Greater Sydney screening attendees were spatially joined to residential state suburbs (SSCs) (n = 799). SSC-level sociodemographic measures included proportions of: women speaking English at home; university-educated; full-time employed; and dwellings with motor-vehicles. A geographic information system identified each woman’s closest venue to home, and venue co-location with bus-stop, train-station, hospital, general practitioner, and shop(s). Multilevel logistic models estimated associations between environmental measures and closest venue attendance. Attendance at closest venue was 59.4%. Closest venue attendance was positively associated with SSC-level women speaking English but inversely associated with SSC-level women university-educated, full-time employed, and dwellings with motor-vehicles. Mobile venue co-location with general practitioner and shop was positively, but co-location with bus-stop and hospital was inversely associated with attendance. Attendance was positively associated with fixed venue co-location with train-station and hospital but inversely associated with venue co-location with bus-stop, general practitioner, and shop. Program planners should consider these features when optimising service locations to enhance utilisation. Some counterintuitive results necessitate additional investigation.

Influence of competitive intensity on stadium attendance. An analysis of the French football Ligue 1 over the period 2009-2019 through a visualization system

ABSTRACT The relationship between competitive balance or intensity and venue attendance has been extensively tested in the literature. These studies have used complex metrics and econometric testing. This does not favour their understanding and application by managers. This article investigates, over a 10 years period (2009–2019), the influence of competitive intensity on stadium attendance for the French men’s football Ligue 1 through a visualization approach. The use of this method provides visual information via a single chart per season about the influence of competitive intensity on attendance, depending on the moment in the season and the sporting stakes. This means that managers can look at relevant information in one single chart. The article shows the positive influence on attendance of competitive intensity in relation to the different sporting stakes, consistent with previous studies. The visualization approach makes the results easy to grasp for managers, facilitating the identification of managerial implications.

The value of identification scanner technology in monitoring and detecting banned patrons in entertainment precincts

Networked identification (ID) scanner technology is a novel approach to collecting licensed venue attendance data, and potentially reducing alcohol-related violence by detecting banned patrons. Using ID scanner data from three Queensland entertainment precincts (Safe Night Precincts; SNPs), we aim to: (i) examine patterns in patron attendance to licensed venues; and (ii) examine patterns in the detection of banned patrons. We conducted descriptive analyses of licensed venue patron entries between 1 October 2017 and 30 June 2019. Scans during high alcohol hours (Friday and Saturday, 20:00-06:00) were stratified by patron sex and key age groups. We described scans associated with a detected banning notice issued by venues, courts or police across all Queensland SNPs and three key SNPs. ID scanner data showed similar attendance trends across SNPs. The peak licensed venue entry hour was 23:00-23:59, with Saturday being the peak day. Approximately two-thirds of scanned patrons were male, and patrons had a mean age of 25.8 years (SD=8.80). Scanners detected 48 657 attempted entries by banned patrons, with the majority of attempts made by males (85%) aged 18-24 years (61%). This study adds to the limited evidence on the use of ID scanners in the night-time economy and highlights the feasibility of ID scanner use in this setting. Results demonstrate the value of scanners to passively collect data on patrons, identify banned patrons and assist in the enforcement of bans.

Sexual and social networks, venue attendance, and HIV risk among young men who have sex with men

ABSTRACT Objective: This study used a Social network analysis (SNA) approach to describe HIV transmission and venue affiliations among social and sexual networks of young men who have sex with men (YMSM) in Houston, TX. Methods: A total of 34 YMSM indices aged 18–23 years and 23 of their network members were interviewed about their social and sexual networks and venues at which they met and spent time. Results: Participants reported information on 220 friends (mean age = 25.3 years) and 112 sexual partners (mean age = 26.3 years). Participants spent time with friends and sexual partners at similar venues but relied more heavily on social media and dating applications to meet sexual partners. Participants lived in zip codes consistent with high concentrations of HIV positivity. Popularly frequented clubs/gay bars were often 10–20 miles away, also in zip codes with high densities of seropositivity. Conclusion: Both friendship and sexual networks are large, diffuse, and not limited by geography. Participants came from areas with high rates of HIV/AIDS. The venues at which participants recruited sexual partners may present increased opportunities for HIV transmission. HIV prevention interventions should focus on the heightened risk of unknown HIV serostatus.

A Systematic Review of Characteristics of Nonprobability Community Venue Samples of Sexual Minority Individuals and Associated Methods for Assessing Selection Bias.

The majority of research on sexual minority individuals relies on nonprobability community venue samples. These samples are prone to selection bias; however, empirical syntheses of evidence of these biases are not available. We conducted, therefore, a systematic review of published sexual minority health research to summarize methods used to identify characteristics and health outcomes found to differ in nonprobability samples. We searched five health and social science databases to identify observational studies that included a nonprobability sexual minority community sample and applied an empirical method to infer selection bias. We extracted data regarding sociodemographic characteristics, behaviors, and health outcomes and examined whether the nonprobability sample was found to differ disproportionately (over- or underrepresenting the characteristic) based on appropriate statistical tests (p < 0.05 was considered statistically significant). A total of 21 studies were included. Nineteen studies used a cross-sample comparison, one used time/location sampling weights, and one used frequency of venue attendance adjustment to assess differences. The evidence was mostly consistent, that is, associations were in the same direction in >50% of studies examined, for nine variables. Nonprobability community venue samples tended to overrepresent sexual minority individuals with the following characteristics: higher income, current employment, lesbian/gay-identified, greater number of sex partners, past-year sexually transmitted infection diagnosis, suicidal ideation, alcohol use, and substance use; nonprobability community venue samples tended to underrepresent married/partnered sexual minority individuals. This review provides a nuanced empirical picture of aggregate differences in sample characteristics presumed to threaten the validity of nonprobability sexual minority community venue studies, and highlights feasible methods that can be applied to future studies to add specificity to researchers' description of selection biases.

Brief Report: Comparing Sexual Risk Behavior in a High-Risk Group of Men Who Have Sex With Men and Transgender Women in Lima, Peru

Transgender women (TW) and men who have sex with men (MSM) are often conflated in HIV research and prevention programs, despite clear differences that exist in culture and behavior. We examined baseline data from a large treatment-as-prevention study among TW and MSM in Lima, Peru, to assess differences in risk behavior. Baseline assessment included HIV testing and a questionnaire including sociodemographics, sexual behavior, social venue attendance, and drug and alcohol use. Poisson regression with robust standard errors was used to calculate prevalence ratios adjusted for confounding variables [adjusted prevalence ratio (aPR)] and 95% confidence intervals (CIs) comparing the prevalence of covariates related to HIV risk in MSM and TW. Overall, 310 TW and 2807 MSM participated between July 2013 and September 2015 and were included in this analysis. TW engaged in some protective sexual health practices more than MSM, including HIV testing in the last year (aPR = 1.62; 95% CI: 1.42 to 1.84) and condom use at the last sexual encounter (aPR = 1.20; 95% CI: 1.06 to 1.36). TW were more likely to have sex while using alcohol (aPR 1.15, 95% CI: 1.01 to 1.31) or drugs (aPR 2.24, 95% CI: 1.47 to 3.41), have alcohol dependency (aPR 1.38, 95% CI: 1.15 to 1.66), engage in receptive anal sex (aPR 1.31, 95% CI: 1.26 to 1.36), and have received money, gifts, or favors in exchange of anal sex (1.96, 95% CI: 1.74 to 2.20). TW and MSM exhibited distinct risk profiles, suggesting that interventions specifically targeted to each group may provide new opportunities for more effective HIV prevention programs.

Prevalence and correlates of lifetime and recent HIV testing among men who have sex with men (MSM) who use mobile geo-social networking applications in Greater Tokyo.

Men who have sex with men (MSM) are disproportionately burdened by the human immunodeficiency virus (HIV), accounting for 78% of all Japanese male HIV cases in 2016. Over 30% of newly identified HIV infections in Japan are diagnosed as AIDS annually, suggesting a large proportion of people living with HIV were unaware of their own infection status. An estimated two-thirds of Japanese men who have sex with men (MSM) are not attached to the gay community, and previous studies have largely sampled gay venues, thus, previous studies have likely failed to reach many men in this population. This study therefore examined HIV testing prevalence and correlates among MSM in Greater Tokyo who use gay mobile geo-social networking applications (gay mobile apps), which have been found to increase access to MSM not traditionally accessible through venue-based surveys. Among a sample of 1657 MSM recruited through advertisements on gay mobile apps, the prevalence of lifetime and six-monthly HIV testing was 72.8% and 29.7% respectively. In multiple regression analysis, higher lifetime HIV testing was associated with older age, education, HIV knowledge, anal intercourse with regular and casual male partners, and gay venue attendance. Testing was negatively associated with regular male partner condom use, marriage, residing outside central Tokyo and having both male and female partners. These results indicated that MSM who use gay mobile apps in Greater Tokyo do not meet the CDC yearly testing recommendations for high risk populations. Considering limited HIV prevention funding in Japan for MSM, moderate lifetime and recent testing, and the large number of gay mobile app users, utilization of popular gay mobile apps to promote nearby HIV testing facilities may be an effective prevention policy to target non-community attached MSM, particularly at-risk youth and individuals at risk of sudden-onset AIDS.

Time location sampling in men who have sex with men in the HIV context: the importance of taking into account sampling weights and frequency of venue attendance.

Sex between men is the most frequent mode of HIV transmission in industrialised countries. Monitoring risk behaviours among men who have sex with men (MSM) is crucial, especially to understand the drivers of the epidemic. A cross-sectional survey (PREVAGAY), based on time-location sampling, was conducted in 2015 among MSM attending gay venues in 5 metropolitan cities in France. We applied the generalised weight share method (GWSM) to estimate HIV seroprevalence for the first time in this population, taking into account the frequency of venue attendance (FVA). Our objectives were to describe the implementation of the sampling design and to demonstrate the importance of taking into account sampling weights, including FVA by comparing results obtained by GWSM and by other methods which use sample weights not including FVA or no weight. We found a global prevalence of 14.3% (95% CI (12.0-16.9)) using GWSM and an unweighted prevalence of 16.4% (95% CI (14.9-17.8)). Variance in HIV prevalence estimates in each city was lower when we did not take into account either the sampling weights or the FVA. We also highlighted an association of FVA and serological status in the most of investigated cities.

Statistical adjustment of network degree in respondent-driven sampling estimators: Venue attendance as a proxy for network size among young MSM

We introduce a new venue-informed network degree measure, which we applied to respondent-driven sampling (RDS) estimators. Using data collected from 746 young MSM in 2014–2016 in Chicago, IL, and Houston, TX, we estimated the population seroprevalence of HIV and syphilis and risk/protective behaviors, using RDS estimates with self-reported network size as a standard degree measure as well as our proposed venue-informed degree measure. The results indicate that the venue-informed degree measure tended to be more efficient (smaller variance) and less biased than the other measure in both cities sampled. Venue attendance-adjusted network size may provide a more reliable and accurate degree measure for RDS estimates of the outcomes of interest.

HIV-Risk Behaviors and Social Support Among Men and Women Attending Alcohol-Serving Venues in South Africa: Implications for HIV Prevention.

Alcohol use is associated with increased HIV-risk behaviors, including unprotected sex and number of sex partners. Alcohol-serving venues can be places to engage in HIV-related sexual risk behaviors, but are also important sites of social support for patrons, which may mitigate risks. We sought to examine the relationship between alcohol-serving venue attendance, social support, and HIV-related sexual risk behavior, by gender, in South Africa. Adult patrons (n=496) were recruited from six alcohol-serving venues and completed surveys assessing frequency of venue attendance, venue-based social support, and recent sexual behaviors. Generalized estimating equations tested associations between daily venue attendance, social support, and sexual behaviors, separately by gender. Interaction effects between daily attendance and social support were assessed. Models were adjusted for venue, age, education, and ethnicity. Daily attendance at venues was similar across genders and was associated with HIV-related risk behaviors, but the strength and direction of associations differed by gender. Among women, daily attendance was associated with greater number of partners and higher proportion of unprotected sex. Social support was a significant moderator, with more support decreasing the strength of the relationship between attendance and risk. Among men, daily attendance was associated with a lower proportion of unprotected sex; no interaction effects were found for attendance and social support. Frequent venue attendance is associated with additional HIV-related risks for women, but this risk is mitigated by social support in venues. These results were not seen for men. Successful HIV interventions in alcohol-serving venues should address the gendered context of social support and sexual risk behavior.

Understanding the attendance at cultural venues and events with stochastic preference models

Abstract This study proposes an alternative approach to the usual cognitive investigation of cultural venue and event attendance. This approach is based on stochastic preference theory. Specifically, the study utilises two well-known stochastic models of consumer behaviour: the NBD model and NBD-Dirichlet model to predict attendance behaviour at cultural venues and events. Using data from a large national survey across a range of cultural venues and events in Australia, including art galleries, museums, zoological parks and aquariums, botanic gardens, archives, music concerts, theatre performances, dance performances, musicals and operas, and cinemas, the study shows that stochastic preference theory is able to predict the attendance at cultural venues and events. This theory has important implications for marketers of cultural venues and events, such as which segments of attendees should be targeted, predicting future attendance behaviour, as well as evaluating the effectiveness of marketing activities such as price promotion and advertising.

“Wine you get every day, but a child you can't replace”: The perceived impact of parental drinking on child outcomes in a South African township

Objective: This study explored the perceived impact of parental drinking on children in a South African township where alcohol abuse is prevalent and high levels of existing poverty and violence may exacerbate potential consequences on children.Method: Qualitative in-depth interviews were conducted with 92 male and female participants recruited from alcohol-serving venues in Cape Town, South Africa.Results: Grounded theory analyses revealed three major aspects of parental drinking — intoxication, venue attendance and expenditures on alcohol — which participants linked to negative proximal outcomes (e.g., child neglect, abuse and exposure to alcohol culture) and long-term outcomes (e.g., fractured parent–child relationships and problematic youth behaviours). In addition, preliminary accounts from some participants suggested that parents may experience tensions between desires to reduce drinking for child-related reasons and complex factors maintaining their drinking behaviour, including the use of alcohol to cope with stressors and trauma.Conclusions: This study provides novel insights into the consequences and motivations of parental drinking in a high-risk context. Contextual risks (e.g., poverty and violence) that exacerbate the impact of parental drinking on children may be the same factors that continue to shape intergenerational alcohol use in this community. Findings highlight opportunities for further research and interventions to support child protection in South Africa.

Design-based inference in time-location sampling.

Time-location sampling (TLS), also called time-space sampling or venue-based sampling is a sampling technique widely used in populations at high risk of infectious diseases. The principle is to reach individuals in places and at times where they gather. For example, men who have sex with men meet in gay venues at certain times of the day, and homeless people or drug users come together to take advantage of services provided to them (accommodation, care, meals). The statistical analysis of data coming from TLS surveys has been comprehensively discussed in the literature. Two issues of particular importance are the inclusion or not of sampling weights and how to deal with the frequency of venue attendance (FVA) of individuals during the course of the survey. The objective of this article is to present TLS in the context of sampling theory, to calculate sampling weights and to propose design-based inference taking into account the FVA. The properties of an estimator ignoring the FVA and of the design-based estimator are assessed and contrasted both through a simulation study and using real data from a recent cross-sectional survey conducted in France among drug users. We show that the estimators of prevalence or a total can be strongly biased if the FVA is ignored, while the design-based estimator taking FVA into account is unbiased even when declarative errors occur in the FVA.

The comparability of men who have sex with men recruited from venue-time-space sampling and facebook: a cohort study.

BackgroundRecruiting valid samples of men who have sex with men (MSM) is a key component of the US human immunodeficiency virus (HIV) surveillance and of research studies seeking to improve HIV prevention for MSM. Social media, such as Facebook, may present an opportunity to reach broad samples of MSM, but the extent to which those samples are comparable with men recruited from venue-based, time-space sampling (VBTS) is unknown.ObjectiveThe objective of this study was to assess the comparability of MSM recruited via VBTS and Facebook.MethodsHIV-negative and HIV-positive black and white MSM were recruited from June 2010 to December 2012 using VBTS and Facebook in Atlanta, GA. We compared the self-reported venue attendance, demographic characteristics, sexual and risk behaviors, history of HIV-testing, and HIV and sexually transmitted infection (STI) prevalence between Facebook- and VTBS-recruited MSM overall and by race. Multivariate logistic and negative binomial models estimated age/race adjusted ratios. The Kaplan-Meier method was used to assess 24-month retention.ResultsWe recruited 803 MSM, of whom 110 (34/110, 30.9% black MSM, 76/110, 69.1% white MSM) were recruited via Facebook and 693 (420/693, 60.6% black MSM, 273/693, 39.4% white MSM) were recruited through VTBS. Facebook recruits had high rates of venue attendance in the previous month (26/34, 77% among black and 71/76, 93% among white MSM; between-race P=.01). MSM recruited on Facebook were generally older, with significant age differences among black MSM (P=.02), but not white MSM (P=.14). In adjusted multivariate models, VBTS-recruited MSM had fewer total partners (risk ratio [RR]=0.78, 95% CI 0.64-0.95; P=.01) and unprotected anal intercourse (UAI) partners (RR=0.54, 95% CI 0.40-0.72; P<.001) in the previous 12 months. No significant differences were observed in HIV testing or HIV/STI prevalence. Retention to the 24-month visit varied from 81% for black and 70% for white MSM recruited via Facebook, to 77% for black and 78% for white MSM recruited at venues. There was no statistically significant differences in retention between the four groups (log-rank P=.64).ConclusionsVBTS and Facebook recruitment methods yielded similar samples of MSM in terms of HIV-testing patterns, and prevalence of HIV/STI, with no differences in study retention. Most Facebook-recruited men also attended venues where VTBS recruitment was conducted. Surveillance and research studies may recruit via Facebook with little evidence of bias, relative to VBTS.

Prevalence of sexual victimization and correlates of forced sex in Japanese men who have sex with men.

Studies of men who have sex with men (MSM) in diverse geographic and cultural contexts have identified health challenges affecting this population. MSM might be particularly vulnerable to sexual victimization and forced sex. The aim of this research study was to examine prevalence of sexual victimization and correlates of forced sex among Japanese MSM. We recruited a sample of 5,731 Japanese MSM who completed an internet-administered survey. Participants reported on history of different types of sexual victimization, unprotected anal sex, other health risk behaviors, exposure to gay-related teasing and bullying, depression, and suicidality. Over one-fifth of the sample (21.4%) reported experiencing at least one form of sexual victimization, and 8.7% reported a history of forced sex. MSM who had ever experienced forced sex were significantly more likely to report experiencing psychological risks (depression OR = 1.55, 95% CI = 1.28–1.89; attempted suicide OR = 2.25, 95% CI = 1.81–2.81; other forms of bullying OR = 1.38, 95% CI = 1.13–1.68) and other behavioral risks (unprotected anal sex OR = 1.56, 95% CI = 1.29–1.90; sex venue attendance OR = 1.27, 95% CI = 1.04–1.54; methamphetamine use OR = 1.57, 95% CI = 1.05–1.36), compared to MSM who had not experienced forced sex. Efforts to develop holistic and integrated health services for Japanese MSM are warranted, particularly related to psychosocial determinants of HIV prevention. However, due to cultural factors that emphasize familial and social relations and that stigmatize same-sex behavior, Japanese MSM might experience challenges to seeking social support and health services. Interventions must be provided in safe and non-judgmental settings where Japanese MSM feel comfortable disclosing their health and social support needs.

Socialization patterns and their associations with unprotected anal intercourse, HIV, and syphilis among high-risk men who have sex with men and transgender women in Peru.

The association of socialization patterns with unprotected anal intercourse (UAI) and HIV/STI prevalence remains underexplored in men who have sex with men (MSM) and transgender women (TW) in developing country settings. We evaluated the correlation of UAI, HIV, and syphilis with MSM/TW venue attendance and social network size among high-risk MSM and TW in Peru according to self-reported sexual identity. Frequency of venue attendance and MSM/TW social network size were lowest among heterosexual MSM and highest among TW respondents. Attendance (frequent or occasional) at MSM/TW venues was associated with increased odds of insertive UAI among heterosexual participants. Frequent venue attendance was associated with increased odds of receptive UAI among gay/homosexual, bisexual, and TW participants. Further investigation of the differing socialization patterns and associations with HIV/STI transmission within subgroups of Peruvian MSM and TW will enable more effective prevention interventions for these populations.
