Chatters on the Internet: a special target group for HIV prevention

Latent Class Analysis of Online Platforms for Partner-Seeking and Sexual Behaviors Among Men Who Have Sex with Men from Central Kentucky

Little is known whether engagement in sexual behaviors associated with potential HIV risks differs by subgroups of men who have sex with men (MSM), who are distinct regarding patterns of use of online tools for partner-seeking. Using latent class analysis, we revealed four classes of app-using MSM (n = 181, 18-34 y.o., 82.4% identified as White and non-Hispanic) residing in Central Kentucky: the Grindr/Tinder class; the Poly App Use class of MSM-oriented apps; the General Social Media class, and the Bumble class. Unadjusted penalized logistic regressions showed associations of the Poly App Use class with increased numbers of receptive anal sex partners and reporting condomless receptive anal sex. Adjusting for other covariates, poly app users versus others were more likely to be older (25-34 vs. 18-24, AOR = 3.81, 95%CI = 1.70-9.03), to report past six-month illicit drug use (AOR = 2.93, 95%CI = 1.25-7.43) and to have ever used pre-exposure prophylaxis (AOR = 2.79, 95%CI = 1.10-7.12). Poly app users had behavior profiles associated with an elevated HIV risk and also reported HIV-related protective behaviors likely indicating increased risk awareness among this class. Our findings warrant differentiation of behavior profiles by patterns of app use and suggest not to generalize sexual behaviors associated with potential HIV risks to all app-using MSM.

Online Partner Seeking and Sexual Behaviors Among Men Who Have Sex With Men From Small and Midsized Towns: Cross-sectional Study

BACKGROUND

Men who have sex with men (MSM) residing outside of large urban areas are underrepresented in research on online partner seeking and sexual behaviors related to transmission of HIV.

OBJECTIVE

We aimed to determine associations between the use of the internet or social networking apps (online tools) to meet partners for sex, dating, or for both purposes (online partner seeking) and sexual behaviors among MSM residing in small and midsized towns in Kentucky, United States.

METHODS

Using peer-referral sampling and online self-administered questionnaires, data were collected from 252 men, aged 18 to 34 years, who had recently (past 6 months) engaged in anal sex with another man and resided in Central Kentucky. Using multivariable logistic regression models, we assessed associations of online partner seeking and HIV-related sexual behaviors.

RESULTS

Most (181/252, 71.8%) of the participants reported using online tools for partner seeking. Of these 181 respondents, 166 (91.7%) had used online tools to meet partners for sex (n=45, 27.1% for sex only; and n=121, 72.9% for sex and dating) and 136 (75.1%) had used online tools to meet partners for dating (n=15, 11% for dating only; and n=121, 89% for sex and dating). Adjusted analyses revealed that MSM who had engaged in condomless insertive and receptive anal intercourse were less likely to report online partner seeking (adjusted odds ratio [aOR] 0.22, 95% CI 0.07-0.68; P=.009 and aOR 0.25, 95% CI 0.10-0.66; P=.005, respectively). Increased number of insertive and receptive anal sex partners and substance use before or during sex were associated with higher odds of online partner seeking (aOR 1.31, 95% CI 1.11-1.55; P=.001; aOR 1.20, 95% CI 1.05-1.39; P=.008; and aOR 2.50, 95% CI 1.41-4.44; P=.002, respectively).

CONCLUSIONS

Among MSM who reside outside of large urban areas and practice online partner seeking, HIV risk-reduction interventions should address safer sex practices, including the risks for HIV transmission associated with alcohol or drug use before or during sex. MSM who do not practice online partner seeking are in need of continued outreach to reduce condomless anal sex.

Understanding internet sex-seeking behaviour and sexual risk among young men who have sex with men: evidences from a cross-sectional study

OBJECTIVE

Internet sex-seeking is common among young men who have sex with men (MSM). However, research examining its association with risky sexual behaviour has produced mixed findings, possibly due to various operational definitions of internet sex-seeking which fail to account for its multi-dimensionality. This study purposed to: (1) examine if the way internet sex-seeking behaviour is operationalised influences its association with risky sexual behaviour (unprotected anal intercourse (UAI) and casual sex) and (2) determine the association of each operational definition with sexual risk.

METHODS

We recruited 263 sexually-experienced young MSM (18-29 years) and operationalised internet sex-seeking behaviour in four ways: (i) ever used the internet to meet other men, (ii) currently own a profile on a website dedicated to meeting other men, (iii) ever physically met a man you initially met online and (iv) ever had sex with a man you met online. Using binomial regression, we examined the association of each operationalisation with UAI and casual sex.

RESULTS

Only MSM who reported physically meeting a man they met online and those who ever had sex with a man they met online were more likely to report a history of UAI (p<0.05), while MSM who engaged in all forms of internet sex-seeking were more likely to engage in casual sex (p<0.05). However, the strength of these associations varied according to the mode of operationalisation.

CONCLUSIONS

The way internet sex-seeking is operationalised in research is differentially associated with sexual risk. Against this backdrop, the utility of these operational definitions in future research and inferences drawn from such research must be interpreted with caution. Findings have important implications for sexual health research and methodology, survey development, sexual health prevention interventions, and evaluating sexual risk among young MSM.

E-health: potential benefits and challenges in providing and accessing sexual health services

Background

E-health has become a burgeoning field in which health professionals and health consumers create and seek information. E-health refers to internet-based health care and information delivery and seeks to improve health service locally, regionally and worldwide. E-sexual health presents new opportunities to provide online sexual health services irrespective of gender, age, sexual orientation and location.

Discussion

The paper used the dimensions of the RE-AIM model (reach, efficacy, adoption, implementation and maintenance) as a guiding principle to discuss potentials of E-health in providing and accessing sexual health services. There are important issues in relation to utilising and providing online sexual health services. For healthcare providers, e-health can act as an opportunity to enhance their clients’ sexual health care by facilitating communication with full privacy and confidentiality, reducing administrative costs and improving efficiency and flexibility as well as market sexual health services and products. Sexual health is one of the common health topics which both younger and older people explore on the internet and they increasingly prefer sexual health education to be interactive, non-discriminate and anonymous. This commentary presents and discusses the benefits of e-sexual health and provides recommendations towards addressing some of the emerging challenges.

Future directions

The provision of sexual health services can be enhanced through E-health technology. Doing this can empower consumers to engage with information technology to enhance their sexual health knowledge and quality of life and address some of the stigma associated with diversity in sexualities and sexual health experiences. In addition, e-sexual health may better support and enhance the relationship between consumers and their health care providers across different locations. However, a systematic and focused approach to research and the application of findings in policy and practice is required to ensure that E-health benefits all population groups and the information is current and clinically valid and effective, including preventative approaches for various client groups with diverse needs.

HealthMpowerment.org: development of a theory-based HIV/STI website for young black MSM

Black men who have sex with men (BMSM) are disproportionately affected by the HIV epidemic, yet few prevention interventions have been developed specifically for them. Recent studies suggest that the Internet is a promising intervention delivery avenue. We describe results from our formative work in developing a theory-based online HIV/STI prevention intervention for young BMSM including focus groups, semistructured interviews, and usability testing. The Intervention, HealthMpowerment.org , was created based on the Institute of Medicine's integrated model of behavior change with extensive input from young BMSM. Key interactive Web site features include live chats, quizzes, personalized health and "hook-up/sex" journals, and decision support tools for assessing risk behaviors. Creating an interactive HIV/sexually transmitted infection web site for BMSM was a complex process requiring many adjustments based on iterative feedback throughout all development stages. Preliminary satisfaction, content acceptability, and usability findings support the use of the Internet to deliver risk reduction messages to young BMSM.

Compulsive sexual behavior and risk for unsafe sex among internet using men who have sex with men

The present study explored the relationship between compulsive sexual behavior (CSB) and unprotected anal intercourse (UAI) for men who have sex with men (MSM) across a number of ethnic/racial groups and who used the Internet to seek sexual partners. A sample of 2,716 MSM (512 Asian, 445 Black, 683 Latino, 348 Other, 728 White) completed on online survey that collected information about their sexual behaviors with partners met online and offline. The survey also included the Compulsive Sexual Behavior Inventory (CSBI). Consistent with the notion that CSB is a stable trait, higher scores on the CSBI were associated with greater odds for engaging in UAI, regardless of the context in which sex partners were met (online or offline). Differences in median CSB scores were generally similar across racial and ethnic groups. The median CSB score was significantly higher for HIV-positive participants than for HIV-negative participants. HIV-prevention interventions are needed among MSM, but should take into account that some may be resistant to risk reduction strategies because of CSB.

Use of gay Internet sites and views about online health promotion among men who have sex with men

In May-June 2002, 4,974 men who have sex with men (MSM), average age 31 years, completed a self-administered questionnaire online accessed through two popular gay Internet sites in the UK (gaydar and gay.com UK). Most men were white (95%), employed (83%), lived in the UK (91%) and self-identified as gay (85%). Nearly half (46%) had not been tested for HIV, while 6% said they were HIV-positive. One-third (31%) reported high-risk sexual behaviour in the previous three months, i.e. unprotected anal intercourse with a partner of unknown or discordant HIV status. Nearly all the men (82%) had looked for a sexual partner on the Internet and three-quarters had been doing so for more than a year. Almost half the men (47%) said they preferred to meet men through the Internet rather than in bars or other 'offline' venues. Although nearly 40% of men said the most important reason for using these Internet sites was to find sexual partners, a further 17% said they primarily used them to have contact with other men, 16% because they were bored, 12% for entertainment, 4% because they were lonely and 3% because they were addicted to it. The majority of men in this survey had favourable attitudes towards online health promotion. Most men thought that Internet sites should allow health workers into chat-rooms (75%); would click on a banner to find out about sexual health (78%); and said if they met a health worker in a chat-room they would find out what they had to say (84%). In multivariate analysis, being HIV-positive, older age and high-risk sexual behaviour were all independently associated with an increased frequency of using the Internet to look for sex (p<0.05). The Internet has emerged as an important meeting place for men who have sex with men. As online HIV prevention initiatives are developed it will be important to monitor the extent to which the favourable attitudes seen here are reflected in preventive behaviours.

Online sex-seeking behaviors of men who have sex with men in New York City

The ongoing HIV epidemic among men who have sex with men (MSM) in New York City and the increased use of Internet sexual social networking websites by MSM fosters a need to understand the characteristics and sex-related behaviors of this group. The authors conducted an online survey of 195 MSM who use sexual social networking websites in New York City. Demographic characteristics, sexual sensation seeking, and HIV optimism-skepticism were compared among participants reporting sex with and without condom use (safe sex and high-risk sex, respectively) with partners met online. There was no difference in income, education, race, or employment status between the groups. The groups differed significantly in age, sexual sensation seeking, and HIV optimism-skepticism. In a multivariate logistic regression both HIV optimism-skepticism (p < .05) and sexual sensation seeking (p < .05) were significant predictors of high-risk sexual behavior (pseudo-R(2) = .24). This information should be considered when developing interventions for this group. For example, to reach those with high sexual sensation seeking, public health professionals should design sex-positive prevention messages for online distribution that highlight safer sex without condemning risky sexual practices.

A pilot intervention utilizing Internet chat rooms to prevent HIV risk behaviors among men who have sex with men

OBJECTIVES

Chat room-based prevention interventions for human immunodeficiency virus (HIV) are being implemented to reduce the risk of HIV exposure, infection, and re-infection among men who have sex with men (MSM).

METHODS

Our community-based participatory research partnership implemented a chat room-based intervention known as Cyber-Based Education and Referral/Men for Men (CyBER/M4M). We collected both quantitative and qualitative data to describe the characteristics of chat-room participants ("chatters") and their HIV risks and prevention needs, and to document intervention delivery.

RESULTS

Of the 1,851 chatters who participated in the 18-month intervention, 210 completed the online assessment. The mean age was 30 years. Although the majority self-identified as gay, 25.8% self-identified as bisexual. More than half self-identified as white and one-third as black or African American. A total of 8.6% reported being HIV-positive and 14.8% reported never having been tested for HIV. Grounded theory analysis of transcripts from chat-room instant-message discussions identified 13 thematic categories related to chatter characteristics, prevention needs, and intervention delivery. Chatters were looking for sexual partners, were not open about their orientation, lacked basic information about HIV, had questions about how to be tested, and perceived a lack of general community resources to meet their needs. Furthermore, CyBER educators had to understand and respect the online culture, build trust, and deliver well-crafted and focused messages.

CONCLUSIONS

Chat room-based interventions hold promise to systematically reach Internet communities of MSM, a group that is particularly at risk for infection with HIV and other sexually transmitted diseases.

Reaching and retaining high-risk HIV/AIDS clients through the Internet

The Internet is a popular way for people to meet casual sex partners. However, online outreach remains largely unexplored to promote voluntary counseling and testing for HIV. The Student Health Action Coalition's HIV testing program (SHAC-HIV) targets high-risk clients through tailored Internet outreach via chat rooms, social networking sites, and online forums. The SHAC-HIV model also demonstrates that nontraditional testing sites can provide low-cost, client-centered, high-quality services to support increased demand for HIV-testing services. Within the clinic, SHAC-HIV's testing model includes four major components: (a) reliance on a team of well-trained health sciences student volunteers; (b) rapid oral-fluid HIV tests; (c) universal, consent-based testing with client-centered health education and counseling; and (d) coordinated referrals for follow-up testing, treatment, and care. This approach reaches high-risk clients as well as undiagnosed infections. In 2007, there were nine confirmed positive results out of 389 tests, yielding a 2.3% positivity rate. This positivity percentage is higher than any other nontraditional testing site in North Carolina. This article describes the SHAC-HIV outreach and voluntary counseling and testing program with the aim of encouraging adoption of the model by other nontraditional testing sites.

First anal intercourse and condom use among men who have sex with men in Switzerland

The aim of this study was to analyze the circumstances of first anal intercourse (FAI) among men who have sex with men (MSM) and to identify factors associated with condom use at this event. We conducted a cross-sectional survey among a convenience sample of MSM living in Switzerland (N = 2,200). Anonymous questionnaires were distributed using Swiss gay communication channels (newspapers, associations, websites) and gay bathhouses. We gathered data on age at FAI, age of the partner, degree of familiarity with him, place of first meeting, and sociodemographic indicators. We did not ask whether FAI was insertive, receptive, or both. Data were stratified by birth year classes (birth cohorts). The median age at FAI fell from 24.5 years among men born before 1965 to 20.0 years among those born between 1975 and 1984 (p < .001). In each birth cohort, between 20 and 30% reported a partner 10 years older or more. Of eight variables examined in multivariate analysis, two were positively associated with condom use: age of participants at FAI and low degree of familiarity between partners. Conversely, large age discrepancy between partners was negatively associated with condom use. In conclusion, our data showed that early initiation of anal intercourse and large age discrepancy were associated with risk taking: a pattern of initiation that may facilitate HIV transmission from older to younger cohorts of MSM. Since age at FAI is on the decrease, there is an urgent need to heighten awareness of prevention actions regarding sexual debut of MSM.

Service engagement with high-risk men who have sex with men: challenges and implications for social work practice

This article reviews social work challenges in treatment engagement of men who have sex with men (MSM) and details issues co-morbidity creates for reaching HIV-positive MSM engaged in substance abuse. The literature reviewed within the article identifies HIV and substance use risk factors influencing out of care dynamics and examines relevant research identifying contextual and cultural factors central to achieving cultural competence. The article examines aspects of cultural sensitivity and competence in service development and engagement and identifies service qualities and characteristics social workers can incorporate into practice and programs to increase the likelihood of successful engagement and treatment adherence.

Improving recruitment and retention for an online randomized controlled trial: experience from the Youthnet study

The objective of the study was to present recruitment and retention findings for an Internet based HIV prevention trial evaluated using a randomized controlled design among 15-25-year-olds accessing a website on the Internet. We used a combination of automated electronic and personalized approaches to increase and diversify recruitment, verify participant eligibility and increase retention. We posted 3.5 million banner advertisements, 9354 individuals clicked on the advertisement, 8950 completed an eligibility screener and 3298 a baseline survey; we flagged 675 of these as suspicious and enrolled 2623 individuals. Of these, 2082 (79%) completed a follow-up at one-month and 1398 (53%) completed a two-month follow-up. This retention rate is the highest we have seen for an Internet-based HIV-prevention trial. Our procedures can be replicated in other trials. We stress the importance of using a combination of automated and personalized techniques to increase enrollment, verify eligibility and promote retention.

Characteristics of gay and bisexual men who drop out of a web survey of sexual behaviour in the UK

An invitation to take part in a web survey of sexual behaviour appeared on two popular websites for gay men in the UK in May and June 2003. As soon as men began the survey, their responses were recorded. If they quit before the end, the point at which they stopped was identified. Men clicked into the survey a total of 4,271 times and 2,752 (64%) respondents completed it. The median last question reached by respondents who dropped out was question number 20 out of 158. Multivariate analysis indicated that drop out was related to ethnic group, openness about sexual orientation and age. The results suggest that MSM who use the Internet to seek sexual partners may be younger, more likely to be from an ethnic minority and less open about their sexuality than web surveys indicate. This has implications for the development of online HIV and STI interventions.

Sexual risk taking among young internet-using men who have sex with men

OBJECTIVES

We examined the characteristics of young Internet-using men who have sex with men (MSM) and risks associated with seeking sex online, offline, or through both strategies.

METHODS

Data were obtained from MSM aged 18 to 24 years who completed a 45-minute online survey regarding sex and Internet use in the preceding 3 months.

RESULTS

Significantly more Internet-using MSM who had met sexual partners both online and offline (43%) reported unprotected anal intercourse than did those who had met sexual partners exclusively online (29%) or offline (34%). MSM who met sexual partners exclusively offline reported the fewest partners but the greatest proportion of partnerships involving unprotected anal intercourse (49%). Meeting sexual partners both online and offline (odds ratio [OR]=3.38-58.42) and being drunk (OR=1.57) or high (OR=2.24) increased the odds of having more sexual partners. The same factors increased the odds of having unprotected anal intercourse (online and offline sexual partners, OR=1.60; being drunk, OR=1.43; being high, OR=1.61).

CONCLUSIONS

Risky sexual behavior was prevalent among all of the study subgroups. Our findings suggest that online sex seeking is associated with greater numbers of sexual partners but neither promotes nor discourages unprotected anal intercourse. Regardless of where sexual partners met, being drunk and high were significant risks for unprotected anal intercourse.

Cruising in cyber space: comparing Internet chat room versus community venues for recruiting Hispanic men who have sex with men to participate in prevention studies

Difficulties with recruitment of hidden populations, such as Hispanic men who have sex with men (MSM), have hampered HIV prevention research, leading researchers to explore alternative recruitment modalities such as the Internet. In this paper, we compare the efficiency and cost of recruiting HMSM from Internet chat rooms versus community venues and examine the differences between participants recruited from each type of venue. Internet recruitment was more efficient and somewhat less costly than community recruitment. Although the two groups were comparable in most demographic factors and HIV risk behaviors, Internet recruits were more likely to be bisexual, more likely to be HIV seropositive, had a higher level of education, and reported higher levels of psychological distress and lower levels of gay community attachment. Implications of our findings for using Internet chatrooms as recruitment venues are discussed.

Latino men's sexual behavior with transgender persons

Male-to-female transgender persons are thought to be "vectors" for HIV/STI transmission, yet little quantitative information exists about the risk behavior of their male sexual partners who may serve as a "bridge" for HIV transmission into the general population. As part of an online survey examining the sexual risk behavior of Latino men who have sex with men (N = 1,026), we identified 44 (4%) participants who reported having had sex with a transgender partner. Compared with a randomly selected sub-sample of 200 men who did not report sex with a transgender person, sexual partners of transgender persons were almost three times more likely to have had unprotected sexual intercourse in the last three months. In addition, men who had sex with transgender persons were more likely to be HIV-positive; married, separated, or divorced; identify as bisexual or straight; have sex with women; and live in rural or small town communities. Regression analysis revealed that community size, sexual compulsivity, and having had a transgender partner were independent predictors of unprotected sex. Among Latino men who have sex with men, men with a history of sex with a transgender person appear more likely to be sexually compulsive and at greater risk for HIV and other sexually transmitted infections. These men may, therefore, also serve as a "bridge" for HIV transmission to (as opposed to from) the transgender population.

Are sexual partners met online associated with HIV/STI risk behaviours? Retrospective and daily diary data in conflict

The association between Internet sex-seeking and sexual risk-taking was explored using both retrospective and daily diary methodology. Men who have sex with men (MSM) (N=113) were recruited through a variety of Internet sites. Participants completed retrospective questionnaires on their history of Internet use to seek sexual partners and their engagement in sexual risk-taking behaviours. Participants also completed daily diaries for up to 30 days, which assessed if partners were met through the Internet and what types of sexual contact occurred. Multilevel modelling was used to analyze the daily diary data. The retrospective and daily diary data produced opposite results. In the retrospective data, a history of online sex-seeking was associated with greater numbers of sexual partners in the last year, one-time sex partners, sex without condoms and failure to discuss partners' sexual histories. In the daily diary data, unprotected anal intercourse (UAI) was less likely to occur with partners met online than with partners met by other means. These data suggest that men who engage in high-risk sex with other men use the Internet as a tool for meeting sexual partners, not that meeting partners online causes high-risk sex.

Men Who Have Sex With Men and Recruit Bareback Sex Partners on the Internet: Implications for STI and HIV Prevention and Client Education

Men who have sex with men (MSM) frequently use Internet-based Web sites to recruit sex partners. Although many MSM users of such sites advocate for safe sex practices in their personal profiles, some users actively recruit sexual partners who wish to participate in anal sexual intercourse without the use of condoms, also known as “bareback” sex. Participating in this sexual practice places both sexual partners at higher risk of HIV transmission. In addition, data indicate this behavior is associated with other high-risk activities such as drug use and communication of other sexually transmitted infections. This article summarizes the literature assessing this phenomenon on the Internet. Specific recommendations are provided for clinicians, health educators, and researchers.

Men who have sex with men in Great Britain: comparison of a self-selected internet sample with a national probability sample

OBJECTIVES

To compare the characteristics of a self-selected, convenience sample of men who have sex with men (MSM) recruited through the internet with MSM drawn from a national probability survey in Great Britain.

METHODS

The internet sample (n = 2065) was recruited through two popular websites for homosexual men in Great Britain in May and June 2003. This sample was compared with MSM (n = 117) from the National Survey of Sexual Attitudes and Lifestyles (Natsal), a probability sample survey of adults resident in Great Britain conducted between May 1999 and February 2001.

RESULTS

No significant differences were observed between the samples on a range of sociodemographic and behavioural variables (p>0.05). However, men from the internet sample were younger (p<0.001) and more likely to be students (p = 0.001), but less likely to live in London (p = 0.001) or report good health (p = 0.014). Although both samples were equally likely to report testing for HIV, men from the internet sample were more likely to report a sexually transmitted infection in the past year (16.9% v 4.8%, adjusted odds ratio 4.14, 95% CI 1.76 to 9.74; p = 0.001), anal intercourse (76.9% v 63.3%; p = 0.001) and unprotected anal intercourse in the past 3 months (45% v 36.6%; p = 0.064).

CONCLUSIONS

The internet provides a means of recruiting a self-selected, convenience sample of MSM whose social and demographic characteristics are broadly similar to those of MSM drawn from a national probability survey. However, estimates of high-risk sexual behaviour based on internet convenience samples are likely to overestimate levels of sexual risk behaviour in the wider MSM population.

Characteristics of a sample of men who have sex with men, recruited from gay bars and Internet chat rooms, who report methamphetamine use

Crystal methamphetamine is a highly addictive stimulant that initially gained popularity in the western region of the United States and has spread to all regions of the country. This study was designed to identify factors associated with methamphetamine use among men who have sex with men (MSM) in North Carolina. Participants were recruited in five gay bars and in five geographically defined Internet chat rooms concurrently in 2005 to complete a brief assessment of drug use and other risk behaviors. Of the 1189 MSM who completed the assessment, mean age was 29 years. Two thirds self-identified as black/African American or other minorities, and 25% as bisexual. Nearly 6% reported using methamphetamines during the past 30 days. In multivariable analysis, MSM who reported using methamphetamines were more likely to report higher education; health insurance coverage; inconsistent condom use during anal sex within the past 3 months; a history of sexually transmitted disease (STD) infection; positive HIV serostatus; and use of medications designed to treat erectile dysfunction. A lack of data exists on methamphetamine use among MSM in the southeastern United States, particularly in nonurban regions. Because the southeastern United States carries a disproportionate HIV, AIDS, and STD burden, our findings underscore the need for further research and intervention.

Conducting Internet-based HIV/STD prevention survey research: considerations in design and evaluation

The aim of this paper is to advance rigorous Internet-based HIV/STD Prevention quantitative research by providing guidance to fellow researchers, faculty supervising graduates, human subjects' committees, and review groups about some of the most common and challenging questions about Internet-based HIV prevention quantitative research. The authors represent several research groups who have gained experience conducting some of the first Internet-based HIV/STD prevention quantitative surveys in the US and elsewhere. Sixteen questions specific to Internet-based HIV prevention survey research are identified. To aid rigorous development and review of applications, these questions are organized around six common criteria used in federal review groups in the US: significance, innovation, approach (broken down further by research design, formative development, procedures, sampling considerations, and data collection); investigator, environment and human subjects' issues. Strategies promoting minority participant recruitment, minimizing attrition, validating participants, and compensating participants are discussed. Throughout, the implications on budget and realistic timetabling are identified.

Opportunities for providing web-based interventions to prevent sexually transmitted infections in Peru

The popularity of Internet cafes in Peru, even in poor communities with no modern infrastructure, opens new possibilities to develop online prevention and intervention programs for sexually transmitted diseases.

Increases in sexually transmitted infections and sexual risk behaviour without a concurrent increase in HIV incidence among men who have sex with men in San Francisco: a suggestion of HIV serosorting?

BACKGROUND

Sexually transmitted infections (STI) and unprotected anal intercourse (UAI) have been increasing among men who have sex with men (MSM) in San Francisco. However, HIV incidence has stabilised.

OBJECTIVES

To describe recent trends in sexual risk behaviour, STI, and HIV incidence among MSM in San Francisco and to assess whether increases in HIV serosorting (that is, selective unprotected sex with partners of the same HIV status) may contribute to preventing further expansion of the epidemic.

METHODS

The study applies an ecological approach and follows the principles of second generation HIV surveillance. Temporal trends in biological and behavioural measures among MSM were assessed using multiple pre-existing

DATA SOURCES

STI case reporting, prevention outreach programmatic data, and voluntary HIV counselling and testing data.

RESULTS

Reported STI cases among MSM rose from 1998 through 2004, although the rate of increase slowed between 2002 and 2004. Rectal gonorrhoea cases increased from 157 to 389 while early syphilis increased from nine to 492. UAI increased overall from 1998 to 2004 (p<0.001) in community based surveys; however, UAI with partners of unknown HIV serostatus decreased overall (p<0.001) among HIV negative MSM, and among HIV positive MSM it declined from 30.7% in 2001 to a low of 21.0% in 2004 (p<0.001). Any UAI, receptive UAI, and insertive UAI with a known HIV positive partner decreased overall from 1998 to 2004 (p<0.001) among MSM seeking anonymous HIV testing and at the STI clinic testing programme. HIV incidence using the serological testing algorithm for recent HIV seroconversion (STARHS) peaked in 1999 at 4.1% at the anonymous testing sites and 4.8% at the STI clinic voluntary testing programme, with rates levelling off through 2004.

CONCLUSIONS

HIV incidence among MSM appears to have stabilised at a plateau following several years of resurgence. Increases in the selection of sexual partners of concordant HIV serostatus may be contributing to the stabilisation of the epidemic. However, current incidence rates of STI and HIV remain high. Moreover, a strategy of risk reduction by HIV serosorting can be severely limited by imperfect knowledge of one's own and one's partners' serostatus.

Cybercartography of popular internet sites used by New York City men who have sex with men interested in bareback sex

A systematic method was used to elicit the names of the six most popular free Internet sites used by gay men and other men who have sex with men in New York City, to meet partners for "bareback" sex. An analysis of the sites characteristics shows that men can use mainstream Internet sites, gay-specific sites, and sex-focused sites free of charge to search for bareback sex partners, selecting by location, physical attributes, sexual mode, HIV-serostatus, and other characteristics. Many individuals use these sites, producing the impression that bareback sex is not an oddity confined to just a few. The official language of the bareback sites associates bareback sex with masculinity and courage, prioritizing pleasure, freedom, choice, and intimacy over HIV-transmission prevention. The sites facilitate sexual experimentation and the expansion of bareback networks. Although some consider bareback sex to represent a failure of HIV prevention, this study suggests that harm reduction strategies may be viable within bareback networks.

Meta-analytic examination of online sex-seeking and sexual risk behavior among men who have sex with men

OBJECTIVES

To estimate the percentage of men who have sex with men (MSM) who have used the Internet to look for sex partners and to examine the prevalence of risky sex among MSM who have and have not sought partners online.

METHODS

Meta-analyses were conducted on findings from published English-language studies. High-risk sex was self-reported unprotected anal intercourse (UAI). Analyses were stratified by method of study recruitment (online versus offline venues) and participants' human immunodeficiency virus (HIV) status.

RESULTS

In studies that recruited MSM offline, a weighted mean, based on 15 findings, indicated that 40% (95% confidence interval [CI], 35.2%-45.2%) of MSM had used the Internet to look for sex partners. In 3 findings from offline studies that stratified by participant HIV status, the weighted-mean percentage was higher among HIV-positive (49.6%; 95% CI, 44.9%-54.3%) than HIV-negative/unknown MSM (41.2%; 95% CI, 36.8%-45.6%). UAI with male sex partners was more likely among MSM who sought partners online than MSM who did not (odds ratio, 1.68; 95% CI, 1.18-2.40; k = 11). This group difference was observed for UAI with HIV-serodiscordant as well as HIV-seroconcordant partners, particularly among HIV-positive study participants. HIV-serodiscordant UAI was not more prevalent with partners met online than offline.

CONCLUSIONS

A substantial percentage of MSM use the Internet to look for sex partners, and those who do are more likely to engage in unprotected sex. Additional research is needed to determine whether the Internet may increase risk behavior beyond that which occurs when men meet partners at offline venues.

Changing patterns of sexual behaviour in the era of highly active antiretroviral therapy

PURPOSE OF REVIEW

To describe changing patterns of sexual behaviour in the era of highly active antiretroviral therapy among gay/bisexual men in Europe, Canada, USA and Australia.

RECENT FINDINGS

While there has been a substantial increase in high-risk sexual behaviour among gay men since 1996, this now appears to be levelling off in some cities. Overall the empirical evidence does not support the suggestion that taking highly active antiretroviral therapy or having an undetectable viral load leads to risky sexual behaviour among people with HIV. Nor can HIV treatment optimism alone explain the recent increase in high-risk sexual behaviour. Since 1996, an increasing number of gay men have begun to use the Internet to look for sexual partners. By serosorting on the Internet, HIV-positive men are more likely to meet online, rather than off-line, other HIV-positive men for unprotected sex. While serosorting does not present a risk of HIV transmission to an uninfected person, it does present a risk of other sexually transmitted infections and co-infection with resistant virus for HIV-positive men themselves. This review also explores emerging behaviours such as barebacking and strategic positioning as well as the role of crystal meth and Viagra.

SUMMARY

The review reminds us of the complexity of human and sexual behaviour. Among gay men, sexual behaviour in the era of highly active antiretroviral therapy has been characterized by risk reduction and stabilization as well as increasing risk. These changing patterns provide a new challenge as well as new opportunities for HIV prevention.

HIV behavioral research online

Internet access has caused a global revolution in the way people of all ages and genders interact. Many have turned to the Internet to seek love, companionship, and sex, prompting researchers to move behavioral studies online. The sexual behavior of men who have sex with men (MSM) has been more closely studied than that of any other group online given the abundance of gay-oriented websites and concerns about increasing transmission of HIV and other sexually transmitted infections. Not only does the Internet provide a new medium for the conduct of behavioral research and for participant recruitment into an array of research studies, it has the as yet unrealized potential to reach huge numbers of MSM with innovative harm reduction and prevention messages tailored to individualized needs, interests, and risk behavior. Internet-based research on sexual behavior has many advantages in rapidity of recruitment of diverse samples which include individuals unreachable through conventional methods (i.e., non-gay identified and geographically and socially isolated MSM, etc.). Internet-based research also presents some new methodologic challenges in study design, participant recruitment, survey implementation, and interpretation of results. In addition, there are ethical issues unique to online research including difficulties in verifying informed consent, obstacles to surveying minors, and the ability to assure anonymity. This paper presents a review of Internet-based research on sexual behavior in MSM, a general discussion of the methodologic and ethical challenges of Internet-based research, and recommendations for future interdisciplinary research.

Web-based behavioral surveillance among men who have sex with men: a comparison of online and offline samples in London, UK

OBJECTIVE

To compare the characteristics of men who have sex with men (MSM) surveyed online (through gay Internet chat rooms and profiles) and offline (in community venues) in London, UK.

METHODS

In February and March 2002, 879 MSM completed a self-administered pen-and-paper questionnaire distributed in central London gyms (offline sample). In May and June 2002, 1218 London MSM completed a self-administered questionnaire online, accessed through Internet chat rooms and profiles on gaydar and gay.com.

RESULTS

Compared with men surveyed offline, those surveyed online were significantly less likely to only have sex with men (89 vs. 94%), to be in a relationship with a man (44 vs. 52%), or to have been tested for HIV (68 vs. 80%) (P < 0.001). Men recruited online were also younger (mean age, 34 vs. 36 years) and less likely to have had a higher education (67 vs. 79%) (P < 0.001). However, differences between online and offline samples were less pronounced for HIV-positive men and more pronounced for HIV-negative men and those who had never been tested for HIV. Regardless of HIV status, men recruited online were more likely to report high-risk sexual behavior (i.e., unprotected anal intercourse with a partner of unknown or discordant HIV status) than men surveyed offline (32 vs. 22%, P < 0.001). Men recruited online were also significantly more likely to have used the Internet to look for sex (85 vs. 45%, P < 0.001); for HIV-positive and negative men, seeking sex on the Internet was associated with high-risk sexual behavior (P < 0.01). In multivariate analysis, after controlling for confounding factors, being surveyed online was independently associated with high-risk sexual behavior for HIV-negative and never-tested men (HIV-negative men, adjusted odds ratio for online vs. offline samples, 1.73; 95% CI, 1.23, 2.42; P < 0.01; never-tested men adjusted odds ratio 2.45; 95% CI, 1.40, 4.29; P < 0.01). This was not the case for HIV-positive men (adjusted odds ratio for online vs. offline samples, 1.32; 95% CI, 0.69, 2.50; P = 0.4).

CONCLUSION

The Internet offers valuable opportunities for conducting behavioral surveillance among MSM because it reaches some men who may not be easily accessed in the community yet who are at high risk for HIV and sexually transmitted diseases. Comparisons of the social, demographic, and behavioral characteristics of online and offline samples must, however, take into account the confounding effects of HIV status and seeking sex on the Internet.

Gay men who look for sex on the Internet: is there more HIV/STI risk with online partners?

OBJECTIVE

To examine whether the excess risk for HIV and sexually transmitted infection (STI) seen among gay men who look for sex through the Internet occurs with men they meet online (through the Internet) rather than offline (in bars, clubs, etc).

METHODS

In 2002-2003, 4225 London gay men were surveyed in an HIV treatment clinic, HIV testing clinic, gyms and on UK Internet sites (gaydar and gay.com). All men completed a self-administered questionnaire concerning Internet use and sexual risk behaviour. Unprotected anal intercourse (UAI) with a partner of unknown or discordant HIV status was classified as non-concordant.

RESULTS

Between 40 and 50% of men surveyed in the clinics and gyms used the Internet to look for sex. HIV-positive men who looked for sex through the Internet were more likely to report UAI with HIV-positive casual partners they met online rather than offline (clinic sample: met online only 9.9%, met offline only 3.8%, McNemar P < 0.05). Regardless of HIV status, however, men who looked for sex through the Internet were no more likely to report UAI with non-concordant casual partners they met online than offline (eg, HIV-negative men, Internet sample: met online only 9.7%, offline only 11.1%, McNemar P = 0.6).

CONCLUSIONS

In London, HIV-positive gay men appear to meet casual UAI partners of the same status through the Internet. This presents a risk for STI transmission. However, gay men were no more likely to meet casual UAI partners of unknown or discordant HIV status--which presents a risk for HIV transmission--online rather than offline.

An Internet study of cybersex participants

Cybersex is a subcategory of online sexual activities (OSA) and is defined as when two or more people are engaging in sexual talk while online for the purposes of sexual pleasure and may or may not include masturbation. Cybersex is a growing phenomenon with a significant impact on participants but very little research has been done on this subject to date. This study is the first to attempt to delineate characteristics of those who engage in cybersex. Data were collected through an online questionnaire in Swedish, administered through the Swedish web portal Passagen.se. Out of the total sample (N = 1828), almost a third, both men and women, reported to have engaged in cybersex. A logistic regression analysis showed that age, sex, and sexual orientation were important demographic variables to consider when investigating cybersex. A comparison of interval data showed those engaging in cybersex to have a higher likelihood of spending more time online for OSA and having more offline sex partners than those not engaging in cybersex.

The unexpected movement of the HIV epidemic in the Southeastern United States: transmission among college students

BACKGROUND

Approximately 16 million people are enrolled in institutions of higher learning in the United States. However, college students have not been perceived as at high risk for HIV infection. In early 2003, acute HIV infection was diagnosed in 2 men attending college in North Carolina. We describe an epidemiologic investigation of newly diagnosed HIV infection in men attending college in North Carolina.

METHODS

We reviewed state surveillance records examining new HIV diagnoses in men 18-30 years old between January 1, 2000 and December 31, 2003, living in 69 North Carolina counties. Risk behavior and demographic information for HIV-infected men enrolled in college were compared with HIV-infected male nonenrollees.

RESULTS

Of the 735 records available for review, 84 (11%) were college men. Eighty-seven percent of college men were African American and 92% were men who have sex with men (MSM) or men who have sex with men and women (MSM/W). Compared with noncollege men, college men were more likely to be African American (odds ratio 3.70, 95% CI = 1.86-7.54), to report meeting sex partners at bars or dance clubs (odds ratio 3.01, 95% CI = 1.77-5.10) or on the Internet/chat lines (odds ratio 4.95, 95% CI = 2.53-9.64), or to report use of "ecstasy" or club drugs (odds ratio 4.51, 95% CI = 1.15-15.40). Newly diagnosed HIV infection was found in men in 37 colleges located in North Carolina or surrounding states and a sexual partner network investigation linked 21 colleges, 61 students, and 8 partners of students.

CONCLUSION

We describe an epidemic of HIV infection occurring in North Carolina college students, primarily involving African American MSM and MSM/W. College students represent an at-risk, accessible population, which deserves further HIV prevention interventions.

Implications of Cyberspace Communication: A Role for Physicians

Through the presentation of three clinical case reports and subsequent discussion, it is demonstrated that physicians must begin to familiarize themselves with the health-related implications of online communication, and must proactively address Internet use as it relates to health and well-being. Included case presentations highlight the following: the established association between those seeking sexual partners through the Internet and an increased risk for sexually transmitted disease; the implications of cyber-communication for young people and concerns related to unsafe online behaviors including sharing identifying information with strangers; the potential use of strategically constructed virtual identities to facilitate sexual exploitation; the impact of accelerated intimacy and disinhibition evident in online communication; and the invasive nature of Internet sexual harassment or bullying. Although it is recognized that most online activities do not negatively affect health, doctors must be prepared to ask patients about Internet use and become involved in educating children, teenagers, and parents about safe online relationships to promote optimal physical, mental, and social health.

The Internet as recruitment tool for HIV studies: viable strategy for reaching at-risk Hispanic MSM in Miami?

Although use of the Internet as a vehicle for HIV/STI research is increasing, its viability to recruit at-risk populations such as Hispanic men who have sex with men (HMSM) to participate in community-based HIV studies is in its infancy. We report on the first 171 participants enrolled in an ongoing study exploring use of the Internet to recruit Hispanic men who have sex with men (HMSM) living in Miami-Dade County, Florida to participate in community-based studies. We report our initial success with chat-room recruitment and describe the sexual and drug use practices of the initial set of participants who were recruited through the Internet. In addition, we describe the formative work conducted to develop the Internet recruitment procedures we are testing. In two months, we spent 211 hours recruiting in chat-rooms and engaged 735 chatters. One hundred and seventy-six men came to our community sites; 172 (98%) were eligible and completed an audio computer-assisted self-interview. In the previous six months, 94.7% of participants had anal sex; 48.9% did not use condoms for anal sex or used them inconsistently; and 48.5% had used club drugs. Six-month use rates for individual drugs were: poppers (31.6%), cocaine (15.8%), ecstasy (14%) and crystal methamphetamines (11.7%). Use of club drugs was significantly associated with unprotected insertive and unprotected receptive anal sex. These initial findings point to the Internet's potential as a tool for recruiting at-risk Hispanic MSM for community studies.

Surfing new territory: club-drug use and risky sex among Hispanic men who have sex with men recruited on the Internet

The Internet presents unique and growing opportunities for conducting HIV/ STD research. This article reports on the first 171 participants enrolled in an ongoing study examining use of the Internet to recruit Hispanic men who have sex with men (HMSM) living in an AIDS epicenter to participate in community-based studies. First, it describes initial success with chatroom recruitment. Second, it compares the demographic, psychosocial, and sexual risk practices among HMSM recruited through the Internet who had used club drugs in the last 6 months and those who had not. In 2 months, 211 hours were spent recruiting in chatrooms; 735 chatroom users were engaged. Researchers used a scripted dialogue to describe the study and to invite chatroom users to visit the study's community sites for screening and enrollment. One hundred and seventy-six men came to the community sites; 172 (98%) were eligible and completed an audio-computer assisted self-interview. In the last 6 months, 48.5% of the sample had used club drugs [defined as cocaine, crystal methamphetamines (crystal), amyl nitrites (poppers), Ecstasy, gamma-hydroxybutyrate (GHB), ketamine (Special K), and Viagra]. The proportion of men reporting use of each drug was: cocaine (15.8%), crystal (11.7%), poppers (31.6%), Ecstasy (14%), GHB (3.5%), Special K (3.5%), and Viagra (19.3%). In multivariate analyses, having higher number of sex partners, having higher social isolation scores, and having engaged in unprotected receptive anal intercourse were significantly associated with club-drug use. These initial findings suggest that high-risk HMSM can be successfully recruited through chatroom dialogues to participate in community-based HIV studies. The alarmingly high rates of club-drug use and risky sexual practices among HMSM underscore the need for effective HIV preventive interventions for this population.

Your picture is your bait: use and meaning of cyberspace among gay men

The Internet is seen by many as a form of cyberspace or environment in which to interact and socialise. This research project drew from the data of a quantitative and qualitative study of gay men in Perth, Western Australia. We examined gay men's usage patterns of chat rooms and other social aspects of the Internet to meet sexual partners. We then reviewed in detail the meanings gay men have for the various Internet environments, and the range of friendship, relationship, casual, or esoteric sex-seeking goals. We argue that gay men view and engage with the Internet differently from how they view and engage with other more traditional gay spaces. This different approach influences how interaction between the men, either online or face-to-face, progresses and how assumptions and expectations are built. This has implications for how sexual health promotion interventions determine the appropriate role and relationship they have with these online social spaces.

The Internet and HIV study: design and methods

BACKGROUND

The Internet provides a new meeting ground, especially for gay men, that did not exist in the early 1990s. Several studies have found increased levels of high risk sexual behaviour and sexually transmissible infections (STI) among gay men who seek sex on the Internet, although the underlying processes are not fully understood. Research funded by the UK Medical Research Council (2002-2004) provided the opportunity to consider whether the Internet represents a new sexual risk environment for gay and bisexual men living in London.

METHODS

The objectives of the Internet and HIV study are to: (i) measure the extent to which gay men living in London seek sexual partners on the Internet; (ii) compare the characteristics of London gay men who do and do not seek sex on the Internet; (iii) examine whether sex with Internet-partners is less safe than with other sexual partners; (iv) compare use of the Internet with other venues where men meet sexual partners; (v) establish whether gay men use the Internet to actively seek partners for unprotected anal intercourse; (vi) determine the potential for using the Internet for HIV prevention. These objectives have been explored using quantitative and qualitative research methods in four samples of London gay men recruited and interviewed both online and offline. The four samples were: (i) gay men recruited through Internet chat rooms and profiles; (ii) HIV positive gay men attending an NHS hospital outpatients clinic; (iii) gay men seeking an HIV test in an NHS HIV testing or sexual health clinic; (iv) gay men recruited in the community.

RESULTS

Quantitative data were collected by means of confidential, anonymous self-administered questionnaires (n>4000) completed on-line by the Internet sample. Qualitative data were collected by means of one-to-one interviews (n = 128) conducted either face-to-face or on-line.

CONCLUSION

The strength of the Internet and HIV study is its methodological plurality, drawing on both qualitative and quantitative research among online and offline samples, as well as taking advantage of recent advances in web survey design. The study's findings will help us better understand the role of the Internet in relation to gay men's sexual practice.

Hookups or health promotion? An exploratory study of a chat room-based HIV prevention intervention for men who have sex with men

This study sought to explore an online intervention that was initiated by an AIDS service organization to reduce sexual risk within a geographically-oriented chat room frequented by men who have sex with men (MSM). Analyses of bio lines, user profiles, and chat room discussions were used to understand and characterize the online prevention intervention. Six predominate discussion topics were identified, including (a) sexual risk reduction strategies (e.g., safer "barebacking"), (b) HIV testing options, (c) local alternatives for nonsexual social support, (d) referrals for youth, (e) resources related to "coming out," and (f) access to risk reduction materials and supplies. The perceived anonymity promoted by the Internet and the health educator's established relationship with the men in the chat room contributed to the success of this intervention. This analysis suggests that an online HIV/AIDS prevention intervention may reach MSM inaccessible in traditional venues typically used for intervention delivery.

First evaluation of the NHS direct online clinical enquiry service: a nurse-led web chat triage service for the public

Background

NHS Direct is a telephone triage service used by the UK public to contact a nurse for any kind of health problem. NHS Direct Online (NHSDO) extends NHS Direct, allowing the telephone to be replaced by the Internet, and introducing new opportunities for informing patients about their health. One NHSDO service under development is the Clinical Enquiry Service (CES), which uses Web chat as the communication medium.

Objective

To identify the opportunities and possible risks of such a service by exploring its safety, feasibility, and patient perceptions about using Web chat to contact a nurse.

Methods

During a six-day pilot performed in an inner-city general practice in Coventry, non-urgent patients attending their GP were asked to test the service. After filling out three Web forms, patients used a simple Web chat application to communicate with trained NHS Direct triage nurses, who responded with appropriate triage advice. All patients were seen by their GP immediately after using the Web chat service. Safety was explored by comparing the nurse triage end point with the GP's recommended end point. In order to check the feasibility of the service, we measured the duration of the chat session. Patient perceptions were measured before and after using the service through a modified Telemedicine Perception Questionnaire (TMPQ) instrument. All patients were observed by a researcher who captured any comments and, if necessary, to assisted with the process.

Results

A total of 25 patients (mean age 48 years; 57% female) agreed to participate in the study. An exact match between the nurse and the GP end point was found in 45% (10/22) of cases. In two cases, the CES nurse proposed a less urgent end point than the GP. The median duration of Web chat sessions was 30 minutes, twice the median for NHS Direct telephone calls for 360 patients with similar presenting problems. There was a significant improvement in patients' perception of CES after using the service (mean pre-test TMPQ score 44/60, post-test 49/60; p=0.008 (2-tailed)). Patients volunteered several potential advantages of CES, such as the ability to re-read the answers from the nurse. Patients consider CES a useful addition to regular care, but not a replacement for it.

Conclusions

Based on this pilot, we can conclude that CES was sufficiently safe to continue piloting, but in order to make further judgments about safety, more tests with urgent cases should be performed. The Web chat sessions as conducted were too long and therefore too expensive to be sustainable in the NHS. However, the positive reaction from patients and the potential of CES for specific patient groups (the deaf, shy, or socially isolated) encourage us to continue with piloting such innovative communication methods with the public.

Prevalence and risk behaviors of Chinese men who seek same-sex partners via the internet in Hong Kong

To examine the prevalence of Internet sex networking among men who have sex with men (MSM) in Hong Kong and risk behaviors associated with the behavior, a telephone survey of 15,230 Hong Kong Chinese men aged 18-60 was conducted. Of the 283 active MSM (having engaged in some MSM behaviors in the last 6 months) identified, 17.7% had networked for MSM partners via the Internet in the last 6 months. Younger age (odds ratio [OR] for age < or = 25 vs. age >25 = 4.67, 95% confidence interval [CI] = 2.35-9.28) and being an anal-sex MSM (OR = 4.72, 95% CI=2.36-9.44) were independent predictors of Internet sex networking. Being an Internet sex networker was associated with some risk behaviors such as having contracted a sexually transmitted disease (adjusted OR = 4.79, 95% CI = 1.34-17.11), having had > or = 3 MSM partners (adjusted OR = 4.74, 95% CI = 2.20-10.23), and having engaged in anal sex (adjusted OR = 3.95, 95% CI = 1.89-8.23). HIV prevention programs for MSM should thereby include Internet-based interventions.
