Internet-based health promotion and disease control in the 8 cities: successes, barriers, and future plans

HIV Digital Vaccine Strategy: Proposal for Applying Blockchain in Preventing the Spread of HIV

Background

The HIV epidemic imposes a heavy burden on societal development. Protection of susceptible populations is the most feasible method for eliminating the spread of HIV. In the absence of a biological vaccine, the definitive solution is enabling susceptible populations to recognize and avoid high-risk sexual behavior.

Objective

The objective of this study is to use specific technologies and strategies to establish a system by which high-HIV-risk individuals can determine the HIV infection status of one another anonymously, conveniently, and credibly.

Methods

This study proposes an HIV digital vaccine (HDV) strategy, a decentralized application (Dapp) based on blockchain for use by individuals with a high risk of HIV and accredited testing agencies (ATAs). Following testing, only the HIV-negative results (or linked information) are uploaded to the blockchain, which results in high-risk individuals being able to determine the HIV-negative status of each other anonymously, conveniently, and credibly.

Results

Future work includes the following: (1) a survey of the willingness to use Dapps among high-HIV-risk populations, (2) a larger framework containing both HDV and people living with HIV (PLH) and discussing the influence of HDV on PLH and its possible solutions, and (3) coordinating with the blockchain development team, ATAs, community-based organizations, and third-party organizations to raise funds, develop the Dapp, formulate detailed plans, and publicize and promote it. The exact timeline for achieving these objectives cannot be determined at present.

Conclusions

The HDV strategy may reduce the occurrence of high-risk sexual behavior and effectively protect susceptible populations; combined with current strategies, it is a promising solution to prevent the spread of HIV. The included concepts of decentralized surveillance and surveillance as intervention may spark a change in current infectious disease prevention and control modes to introduce beneficial innovations in public health systems globally.

The Use of Technology for Sexually Transmitted Disease Partner Services in the United States: A Structured Review

BACKGROUND

Since the late 1990s, health departments and sexually transmitted disease (STD) programs throughout the United States have used technologies, such as the Internet and mobile phones, to provide services to persons with a sexually transmitted infection, including human immunodeficiency virus (HIV), and their sex partners, also known as partner services. This study reviewed the published literature to assess and compare partner services outcomes as a result of using technology and to calculate cost savings through cases averted.

METHODS

We conducted a structured literature review of all US studies that examined the use of technology to notify persons exposed to an STD (syphilis, chlamydia, gonorrhea), including HIV, by health care professionals in the United States from 2000 to 2017. Outcome measures, including the number of partners notified, screened or tested; and new positives identified, were captured and cost savings were calculated, when data were available.

RESULTS

Seven studies were identified. Methods used for partner services differed across studies, although email was the primary mode in 6 (83%) of the 7 studies. Only 2 of the 7 studies compared use of technology for partner services to traditional partner services. Between 10% and 97% of partners were successfully notified of their exposure through the use of technology and between 34% and 81% were screened or tested. Five studies reported on new infections identified, which ranged from 3 to 19. Use of technology for partner serves saved programs between US $22,795 and US $45,362 in direct and indirect medical costs.

CONCLUSIONS

Use of technology for partner services increased the number of partners notified, screened or tested, and new infections found. Importantly, the use of technology allowed programs to reach partners who otherwise would not have been notified of their exposure to an STD or HIV. Improved response times and time to treatment were also seen as was re-engagement into care for previous HIV positive patients. Data and outcome measures across the studies were not standardized, making it difficult to generalize conclusions. Although not a replacement for traditional partner services, the use of technology enhances partner service outcomes.

Attitudes About the Use of Geosocial Networking Applications for HIV/STD Partner Notification: A Qualitative Study

Meeting sex partners through geosocial networking (GSN) apps is common among men who have sex with men (MSM). MSM may choose not to exchange contact information with partners met through GSN apps, limiting their own and health departments' ability to notify partners of HIV/STD exposure through standard notification methods. Using online focus groups (four groups; N = 28), we explored the perspectives of U.S. MSM regarding offer of partner notification features through GSN apps. Most participants were comfortable with HIV/STD partner notification delivered via GSN apps, either by partner services staff using a health department profile or through an in-app anonymous messaging system. While most participants expressed a responsibility to notify partners on their own, app-based partner notification methods may be preferred for casual or hard-to-reach partners. However, participants indicated that health departments will need to build trust with MSM app users to ensure acceptable and effective app-based delivery of partner notification.

Providing Online-Based Sexual Health Outreach to Gay, Bisexual, and Queer Men in Ontario, Canada: Qualitative Interviews with Multisectoral Frontline Service Providers and Managers

The Internet is a common tool for gay, bisexual, and other men who have sex with men (MSM) to find sexual partners and sexual health information. Given persistently high human immunodeficiency virus (HIV) infection rates among MSM, it is important to examine the role of online outreach for MSM as part of HIV prevention and care. We provide an overview of the unique perspectives of online sexual health outreach, delivered through AIDS Service Organizations (ASOs) through sociosexual Internet sites and mobile applications. Data were drawn from the qualitative arm of the community-based Cruising Counts study conducted across Ontario from December 2013 to January 2014. ASO online outreach providers and managers (n = 22) were recruited to complete a 1-h in-person/telephone interview to explore in-depth their experiences with, and perspectives on, delivering online outreach services for MSM in Ontario. Thematic analyses were conducted inductively using NVivo 10. Service providers suggested a high demand for online outreach services for MSM. Strengths and advantages of online outreach over face-to-face outreach included anonymity, instant access to services, peer model, and accessing hard-to-reach populations of MSM. Barriers included consistent quality of service, collaborations between companies that own online technologies and outreach service agencies, budgetary and staff capacity issues, and uncertainty of best practices and evaluation parameters for online outreach. Findings from these interviews can inform service providers, policy makers, and researchers on how online sexual health outreach can play a greater role in HIV prevention by better acknowledging and addressing the opportunities and barriers experienced by service providers working with MSM communities online.

Surveillance Among Men Who have Sex with Men in the United States: A Comparison of Web-Based and Venue-Based Samples

Although men who have sex with men (MSM) recruited through web-based and venue-based sampling methods have been compared, no large web-based and venue-based samples using similar survey instruments have been examined in the U.S. This study describes the differences in sociodemographic characteristics and risk behaviors between the 2012 Web-based HIV Behavioral Survey (n = 3221) and 2011 National HIV Behavioral Surveillance (n = 9256). Compared with participants in the venue-based sample, participants in the web-based sample were older, less likely to be black or Hispanic, more likely to have higher socioeconomic status, and more likely to have anal sex without a condom with their last male sex partner. Web-based participants were less likely to have multiple male sex partners, ever injected drugs, been tested for HIV in the past 12 months, and received free condoms than venue-based participants. The method for sampling MSM into a behavioral survey should consider the sub-population of MSM to be reached.

Changing Communities, Changing Spaces: The Challenges of Health Promotion Outreach in cyberspace

This article is a case study of an Internet chat room outreach project in Perth, Western Australia. The CyberReach project sought to adapt current peer based health promotion outreach, training and supervision frameworks to an online outreach setting in a way that was effective and supported by the online community. It targeted marginalised groups to trial the provision of online mental and sexual health promotion incorporating a participatory action research model into its development and implementation. Three 6-week trial periods were conducted and significant changes were made in response to changes in the online environment and to improve sustainability and effectiveness of the protocols. Four themes arose from CyberReach's experience: online group processes are unique due to the creation of extensive personal networks and occurrence of disclosure without face-to-face contact across potentially large geographic barriers; flexibility is required to adapt to technological changes and online community flux; enforcing boundaries and delineating peer education from therapeutic support can be challenging when only using text-based communication; and Internet outreach can be time intensive with small returns in actual community engagement and constant technological up-skilling of staff may be required. Based on the project's experiences we offer the following recommendations when planning similar Internet outreach strategies: Funding and planning groups need to be aware that the Internet environment is constantly changing and planning and funding arrangements need to reflect a capacity to remain flexible; Programs need to be firmly connected to the communities they are outreaching therefore a peer-based education component is strongly encouraged; Careful consideration should be taken regarding data collection so that the environment and the individuals within are respected; Further research needs to be conducted to understand the styles and approaches of different online interactions, and the relative influence of technical platforms, gender and age.

Reaching Suburban Men Who Have Sex With Men for STD and HIV Services Through Online Social Networking Outreach: A Public Health Approach

BACKGROUND

Technology-enabled approaches may reach suburban and rural men who have sex with men (MSM) who lack physical venues, where they live for sexually transmitted disease (STD)/HIV prevention efforts. We evaluated using Grindr, an all-male social networking platform, for STD/HIV prevention services to MSM by a suburban Public Health department.

METHODS

Phase 1 (October 2012-March 2013) focused on acceptability of prevention messages by MSM on Grindr and phase 2 (October 2013-March 2014) Grindr use for implementing testing and linkage-to-care. We compared the number of Public Health encounters with MSM before and after initiation of Grindr use and the proportion of users who remained engaged with Public Health staff after being told they were interacting with a health educator.

RESULTS

For a 6-month period before Grindr outreach, Public Health had 60 contacts with MSM. Contacts increased to 305 MSM in phase 1, of which 168/213 (79%) remained engaged. In phase 2, among 903 MSM contacts, 69% remained engaged. Asian and Hispanic MSM were more likely to remain engaged with outreach staff; white men were more likely to be not engaged. No significant difference in age between engaged and nonengaged MSM was seen.

CONCLUSIONS

Grindr outreach by Public Health in a suburban county seems acceptable to MSM and leads to a 14-fold increase in MSM reached for counseling and education compared with a traditional outreach period. Further evaluation of technology-enabled approaches for STD/HIV prevention in suburban and rural MSM is warranted.

Using Grindr, a Smartphone Social-Networking Application, to Increase HIV Self-Testing Among Black and Latino Men Who Have Sex With Men in Los Angeles, 2014

In Los Angeles County, about 25% of men who have sex with men (MSM) are HIV-positive but unaware of their status. An advertisement publicizing free HIV self-tests was placed on Grindr, a smartphone social-networking application, from April 17 to May 29, 2014. Users were linked to http://freehivselftests.weebly.com/ to choose a self-test delivery method: U.S. mail, a Walgreens voucher, or from a vending machine. Black or Latino MSM ≥ 18 years old were invited to take a testing experiences survey. During the campaign, the website received 11,939 unique visitors (average: 284 per day) and 334 self-test requests. Among 57 survey respondents, 55 (97%) reported that using the self-test was easy; two persons reported testing HIV positive and both sought medical care. Social networking application self-testing promotion resulted in a large number of self-test requests and has high potential to reach untested high-risk populations who will link to care if they test positive.

Emerging trends and persistent challenges in the management of adult syphilis

There are an estimated 10.6 million incident cases of syphilis worldwide each year. We highlight some persistent challenges and emerging trends in the clinical management of syphilis with a particular focus on therapy, serology, diagnostics, and prevention. Decades after the introduction of penicillin, the optimal management of early syphilis continues to be a controversial topic, particularly in the setting of HIV co-infection. Similarly, the need for routine lumbar puncture in HIV co-infected asymptomatic persons is an unanswered question. Despite advances in both automation and point-of-care diagnostics, we continue to rely on indirect measures of disease activity to manage this infection. As syphilis rates in some populations continue to rise, novel and effective prevention strategies are needed.

Impact of a community popular opinion leader intervention among African American adults in a southeastern United States community

We examine the impact of an adapted community popular opinion leader (C-POL) intervention targeting alcohol-using social networks in Southeast Louisiana. A pre-post C-POL was conducted between October 2009 and April 2013, targeting alcohol users. A total of 65 popular opinion leaders were recruited, trained, and deployed into their social networks to diffuse intervention messages. Anonymous community surveys conducted within the venues among 99 male and female participants at baseline and 197 at 6 months to 1 year later revealed significant behavioral and knowledge changes. Average sexual risk score based on 7 sexual risk items declined from 15.3 to 11.9 (p<0.001); the number of vaginal and anal sex partners in the last year decreased from 11.3 to 7.7 and 3.9 to 2.3, respectively (p<0.01); and HIV knowledge score (based on % correct) increased from 67.2 to 76.8% (p<0.001). Findings add to the evidence base surrounding peer interventions.

Twitter: A Novel Tool for Studying the Health and Social Needs of Transgender Communities

BACKGROUND

Limited research has examined the health and social needs of transgender and gender nonconforming populations. Due to high levels of stigma, transgender individuals may avoid disclosing their identities to researchers, hindering this type of work. Further, researchers have traditionally relied on clinic-based sampling methods, which may mask the true heterogeneity of transgender and gender nonconforming communities. Online social networking websites present a novel platform for studying this diverse, difficult-to-reach population.

OBJECTIVE

The objective of this study was to attempt to examine the perceived health and social needs of transgender and gender nonconforming communities by examining messages posted to the popular microblogging platform, Twitter.

METHODS

Tweets were collected from 13 transgender-related hashtags on July 11, 2014. They were read and coded according to general themes addressed, and a content analysis was performed. Qualitative and descriptive statistics are presented.

RESULTS

There were 1135 tweets that were collected in total. Both "positive" and "negative" events were discussed, in both personal and social contexts. Violence, discrimination, suicide, and sexual risk behavior were discussed. There were 34.36% (390/1135) of tweets that addressed transgender-relevant current events, and 60.79% (690/1135) provided a link to a relevant news article or resource.

CONCLUSIONS

This study found that transgender individuals and allies use Twitter to discuss health and social needs relevant to the population. Real-time social media sites like Twitter can be used to study issues relevant to transgender communities.

Setting the scene: locations for meeting sex partners among behaviorally bisexual men in Vientiane, Laos, and opportunities for health promotion

Behaviorally bisexual men (BBM) in Vientiane, Laos report high-risk sexual behaviors. We explore settings for meeting sex partners and associated risk behaviors among BBM in Laos. BBM and their sexual partners were recruited in Vientiane Capital using modified snowball sampling (2010). Settings for usually meeting sex partners and associations with risk behaviors were assessed. Among 88 BBM, the most common settings for men meeting male, kathoey, and female sex partners were private residences (48%, 37%, 51%, respectively) and hospitality settings (39%, 31%, 40%, respectively). Hospitality settings were more commonly reported by heterosexual-identifying BBM, and private residences more commonly reported by bisexual/homosexual-identifying BBM. Inconsistent condom use was high across partners and settings. Meeting partners in hospitality settings was associated with reporting a high number of female sex partners and frequently drinking alcohol before sex. Our results suggest that targeted health promotion initiatives in bars, clubs, and beer-shops could reach a high proportion of high-risk bisexual men, particularly heterosexual-identifying BBM.

Gay and bisexual men's use of the Internet: research from the 1990s through 2013

We document the historical and cultural shifts in how gay and bisexual men have used the Internet for sexuality between the 1990s and 2013-including shifting technology as well as research methods to study gay and bisexual men online. Gay and bisexual men have rapidly taken to using the Internet for sexual purposes: for health information seeking, finding sex partners, dating, cybersex, and pornography. Men have adapted to the ever-evolving technological advances that have been made in connecting users to the Internet-from logging on via dial-up modem on a desktop computer to geo-social-sexual networking via handheld devices. In kind, researchers have adapted to the Internet to study gay and bisexual men. Studies have carefully considered the ethics, feasibility, and acceptability of using the Internet to conduct research and interventions. Much of this work has been grounded in models of disease prevention, largely as a result of the ongoing HIV/AIDS epidemic. The need to reduce HIV in this population has been a driving force to develop innovative research and Internet-based intervention methodologies. The Internet, and specifically mobile technology, is an environment gay and bisexual men are using for sexual purposes. These innovative technologies represent powerful resources for researchers to study and provide outreach.

Craigslist exposed: the Internet-mediated hookup

This research examines how people advertise themselves on Craigslist. The authors develop a framework that highlights 13 resources that heterosexual and homosexual men and women offer in Craigslist advertisements. The results reveal that many heterosexual advertisers offer and seek similar resources on Craigslist, whereas gay men primarily use Craigslist to seek and offer sex. About one-fourth of homosexual advertisers are in committed relationships. The authors build on this finding by exploring the extent to which married men use Craigslist for "hookups." The authors show the extent to which married men solicit responses to 6 different advertisements for sexual encounters that range from safe to high risk.

Strategies to retain participants in a long-term HIV prevention randomized controlled trial: lessons from the MINTS-II study

Achieving satisfactory retention in online HIV prevention trials typically has proven difficult, particularly over extended timeframes. The overall aim of this study was to assess factors associated with retention in the Men's INTernet Study II (MINTS-II), a randomized controlled trial of a sexual risk reduction intervention for men who have sex with men. Participants were recruited via e-mails and banner advertisements in December, 2007 to participate in the MINTS-II Sexpulse intervention and followed over a 12-month period. Retention across the treatment and control arms was 85.2% at 12 months. Factors associated with higher retention included: randomization to the control arm, previous participation in a study by the research team, e-mail and telephone reminders to complete a survey once it was available online, and fewer e-mail contacts between surveys. The results provide evidence that achieving satisfactory retention is possible in online HIV prevention trials, and suggest best practices for maximizing retention.

Methamphetamine use, transmission risk behavior and internet use among HIV-infected patients in medical care, San Francisco, 2008

Methamphetamine use is associated with adverse health outcomes and HIV incidence. Few studies have assessed methamphetamine use, sexual behavior and Internet use among HIV-infected patients. Surveys were administered to a sample of HIV-infected patients seeking medical care in a San Francisco county hospital and university-based clinic. In 2008, 35% of homosexual participants, 26% of heterosexual participants and 11% of female participants reported methamphetamine use in the past year. Of participants, 29% reported using the Internet to find sex partners; Internet-users versus non-Internet-users reported a higher median number of sex partners in 6 months (4 vs. 1), were more likely to report unprotected sex (32 vs. 10%), and higher rates of methamphetamine use in the past 12 months (48 vs. 24%). Given the association among methamphetamine use, increased sex partners and Internet use, the Internet may present a new and effective medium for interventions to reduce methamphetamine-associated sexual risk behavior.

Use of the Internet for the surveillance and prevention of sexually transmitted diseases

The Internet is a relatively new tool in the surveillance and prevention of sexually transmitted infections, and this review examines its global use in this regard. Much use has been made in the form of information collection and dissemination; targeted population engagement through chat rooms, partner notification and other mechanisms; and the provision of testing services and other products. Internet users may need education concerning reputable websites, and public health practitioners need proficiency in the use of social media and marketing.

[Attitudes toward online HIV/sexually-transmitted infection prevention programs and Internet user profiles among men who have sex with men]

OBJECTIVES

To describe the attitudes of men who have sex with men (MSM) toward online HIV/sexually-transmitted infection (STI) prevention programs and to identify and characterize user profiles with regard to their attitudes toward online prevention programs.

METHOD

A survey in gay venues or via the internet was completed by 2,044 participants from Madrid, Barcelona, Bilbao and San Sebastián (Spain). The survey explored socio-demographic variables, sexual behavior and other risk behaviors associated with HIV infection, as well as attitudes toward online prevention programs. The statistical analysis included factor analysis and non-hierarchical cluster analysis.

RESULTS

Most MSM had positive attitudes towards online HIV/STI prevention programs. Factor analysis revealed two factors: online prevention aimed at interaction and online prevention aimed at information. Based on these factors, three user profiles were identified: users oriented toward informative and interactive online prevention (53.5%), users oriented toward interactive online prevention (25.9%) and users were not oriented toward online prevention (20.7%). On characterizing these profiles, we observed a significant presence of men who were not interested in online prevention among those with a lower educational level, bisexual men and HIV-positive men. Conversely, those most receptive to online prevention were men self-identified as gay, those with a bachelors degree, those who had been tested for HIV and those who were HIV-negative.

CONCLUSION

The internet can facilitate sexual health promotion among MSM. Characterization of user profiles offers the possibility of segmenting prevention programs and of combining online and offline strategies.

Evaluation of an innovative internet-based partner notification program for early syphilis case management, Washington, DC, January 2007-June 2008

BACKGROUND

The Internet has become a common venue for meeting sex partners and planning participation in risky sexual behavior. In this article, we evaluate the first 18 months of the Washington, DC, Department of Health Internet-based Partner Notification (IPN) program for early syphilis infections, using the standard Centers for Disease Control and Prevention (CDC) Disease Investigation Specialist (DIS) disposition codes, as well as Washington, DC, Department of Health's IPN-specific outcomes for pseudonymous partners.

METHODS

We analyzed DIS disposition codes and IPN-specific outcomes from all early syphilis investigations initiated January 2007-June 2008. Internet partners were defined as sex partners for whom syphilis exposure notification was initiated by e-mail because no other locating information existed. If the e-mails resulted in additional locating information, we used the standard CDC disposition codes. Alternatively, the following IPN-specific outcomes were used: Informed of Syphilis Exposure, Informed of General STD Exposure, Not Informed or Unable to Confirm Receipt of General STD Exposure.

RESULTS

From the 361 early syphilis patients, a total of 888 sex partners were investigated, of which 381 (43%) were via IPN. IPN led to an 8% increase in the overall number of syphilis patients with at least one treated sex partner, 26% more sex partners being medically examined and treated if necessary, and 83% more sex partners notified of their STD exposure.

CONCLUSIONS

IPN augmented traditional syphilis case management and aided in the location, notification, testing, and treatment of partners. Conversely, without IPN, these 381 partners would not have been investigated.

The intersection between HIV and syphilis in men who have sex with men: some fresh perspectives

Syphilis is increasing in men who have sex with men and disproportionately affects HIV-infected men. Here we review the epidemiology, diagnostic techniques, treatment guidelines, follow-up procedures and control of syphilis. The difference in these factors in HIV-infected men and uninfected men and evidence for this is reviewed. We explain that HIV-infected men are at higher risk of syphilis acquisition as a result of different behavioral factors. Thus, some control strategies may be different for HIV-infected men owing to these factors and also because HIV-infected men are more closely linked with medical care. There is no strong evidence to suggest there should be any differences in diagnostic techniques, treatment guidelines or follow-up procedures between HIV-infected and uninfected men.

Evaluation of an HIV nucleic acid testing program with automated Internet and voicemail systems to deliver results

BACKGROUND

Nucleic acid testing (NAT) in routine HIV testing programs can increase the detection of infected individuals, but the most effective implementation of NAT remains unclear.

OBJECTIVE

To determine how many HIV cases can be identified with NAT and how many persons can be contacted, to identify predictors of acute and early HIV infection cases, and to test reporting of negative results by automated Internet and voicemail systems.

DESIGN

Prospective study.

SETTING

San Diego County, California.

PARTICIPANTS

Persons seeking HIV testing.

MEASUREMENTS

Rates and predictors of HIV infection by stage, notification of positive NAT results, use of automated Internet or voicemail systems to access negative NAT results, and estimated HIV infections prevented.

RESULTS

Of 3151 persons tested, 79 had newly diagnosed cases of HIV: 64 had positive results from rapid HIV test, and 15 had positive results only by NAT (that is, NAT increased the HIV detection yield by 23%). Of all HIV infections, 44% (in 35 persons) were in the acute and early stages. Most participants (56%) and persons with HIV (91%) were men who have sex with men (MSM). All persons with NAT-positive results were notified within 1 week. Of all 3070 uninfected patients, 2105 (69%) retrieved their negative NAT results, with 1358 using the Internet system. After adjustment for covariates, persons reporting MSM behavior, higher incomes, younger ages, no testing at substance abuse rehabilitation centers, no recent syphilis, and no methamphetamine use were more likely to access negative NAT results by either Internet or voicemail systems.

LIMITATION

Findings may not be generalizable to other populations and testing programs.

CONCLUSION

Nucleic acid testing programs that include automated systems for result reporting can increase case yield, especially in settings that cater to MSM.

Efficacy of a web-based intervention to reduce sexual risk in men who have sex with men

To the extent that men who have sex with men (MSM) use the Internet, it serves as a promising medium for behavioral intervention. The present study sought to investigate the efficacy of a web-based skills training and motivational intervention in a randomized trial (N = 112) conducted completely online. After a detailed assessment, MSM were randomly assigned to an online intervention or a control website. The experimental intervention consisted of risk assessment and feedback, motivational exercises, skills training, and education while the control intervention focused on relaxation skills. Follow-up data were collected 3 months later and analyzed with repeated-measures MANOVA. Although both groups evidenced across-the-board reductions in unprotected sex, perhaps due to the detailed assessment, the experimental group showed greater reductions with the riskiest partners, those of positive or unknown serostatus. Thus, this study gives preliminary evidence that a brief web-based intervention offering cognitive behavioral skills training and motivational enhancement can effectively reduce sexual risk in MSM.

Developing a Text Messaging Risk Reduction Intervention for Methamphetamine-Using MSM: Research Note

Men who have sex with men (MSM) who use methamphetamine experience high risks for HIV infection due to sexual transmission behaviors often engaged in when under the influence of methamphetamine. Methamphetamine-using MSM use various forms of information technology (IT) communication such as instant messaging, social networking sites, and websites to facilitate a sexual and/or drug “hook up.” Given the acceptability of IT communication in their daily lives, an IT intervention represents an appropriate strategy to reach and intervene with out-of-treatment, methamphetamine-using MSM. The aim of this study was to conduct formative work to develop a text messaging intervention to reduce methamphetamine use and high-risk sexual behaviors among out-of-treatment MSM, which involved conducting focus groups, community partners’ meetings, and a pre-test intervention. These activities culminated in the development of a two-week, text-messaging intervention that delivered real-time electronic correspondence based on the behavioral change theories of Social Support Theory, Health Belief Model, and Social Cognitive Theory. The focus groups, community meetings, and pre-test were used to identify the IT communication device, the text messages that best support risk reduction and healthier behavioral choices, and logo, flyer and website development. The input and feedback from the target population and community partners were critical to the successful development of a culturally appropriate intervention. The knowledge gleaned from the formative work of this study will be vitally helpful in designing future IT studies.

Telling partners about chlamydia: how acceptable are the new technologies?

Background

Partner notification is accepted as a vital component in the control of chlamydia. However, in reality, many sexual partners of individuals diagnosed with chlamydia are never informed of their risk. The newer technologies of email and SMS have been used as a means of improving partner notification rates. This study explored the use and acceptability of different partner notification methods to help inform the development of strategies and resources to increase the number of partners notified.

Methods

Semi-structured telephone interviews were conducted with 40 people who were recently diagnosed with chlamydia from three sexual health centres and two general practices across three Australian jurisdictions.

Results

Most participants chose to contact their partners either in person (56%) or by phone (44%). Only 17% chose email or SMS. Participants viewed face-to-face as the "gold standard" in partner notification because it demonstrated caring, respect and courage. Telephone contact, while considered insensitive by some, was often valued because it was quick, convenient and less confronting. Email was often seen as less personal while SMS was generally considered the least acceptable method for telling partners. There was also concern that emails and SMS could be misunderstood, not taken seriously or shown to others. Despite these, email and SMS were seen to be appropriate and useful in some circumstances. Letters, both from the patients or from their doctor, were viewed more favourably but were seldom used.

Conclusion

These findings suggest that many people diagnosed with chlamydia are reluctant to use the new technologies for partner notification, except in specific circumstances, and our efforts in developing partner notification resources may best be focused on giving patients the skills and confidence for personal interaction.

Can you hear me now? Limited use of technology among an urban HIV-infected cohort

Recent studies support technology-based behavioral interventions for individuals with HIV. This study focused on the use of cell phone and internet technologies among a cohort of 515 HIV-infected individuals. Socio-demographic and clinic data were collected among individuals presenting at an urban Midwestern university HIV clinic in 2007. Regular internet usage occurred more often with males, Caucasians, those who were employed, had higher income, and were more educated. Higher levels of education and income >$10,000 predicted regular usage when controlling for race, employment, and gender. Cell phone ownership was associated with being Caucasian, employed, more educated, and salary >$10,000. Employment was the only predictor of owning a cell phone when controlling for income, race, and education. Individuals who were <40 years of age, employed, and more educated were more likely to know how to text message. Employment and post-high school education predicted knowledge of text messaging, when controlling for age. Disparities among internet, cell phone, and text messaging usage exist among HIV-infected individuals.

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.

The epidemiology of human immunodeficiency virus infection, sexually transmitted infections, and associated risk behaviors among men who have sex with men in the Mekong Subregion and China: implications for policy and programming

BACKGROUND

Little systematic knowledge is available regarding risk behaviors and the prevalence of human immunodeficiency virus (HIV) and sexually transmitted infections (STI) in populations of men having sex with men (MSM) in the Mekong Subregion and China.

METHODS

Data on HIV/STI prevalence and risk behavior of MSM in the region were collected through Internet searches, were summarized and assessed for their policy and programming implications.

RESULTS

Twenty-four articles, reports and abstracts of research studies were identified for review. High levels of HIV, STI and associated risk behavior were reported among MSM throughout the region. The HIV prevalence among MSM in urban areas varied between 5.5% and 28.3% in Thailand and Cambodia and between 0.0% and 9.4% in Vietnam and China. No HIV/STI prevalence data were available for Lao PDR and Myanmar.

CONCLUSION

Levels of HIV/STI prevalence and risk behavior among MSM in the Mekong Subregion and China are high. Continued monitoring and surveillance and targeted preventive interventions are necessary to stop the spread of HIV in this vulnerable population.

Efficacy of computer technology-based HIV prevention interventions: a meta-analysis

OBJECTIVES

To conduct a meta-analysis of computer technology-based HIV prevention behavioral interventions aimed at increasing condom use among a variety of at-risk populations.

DESIGN

Systematic review and meta-analysis of existing published and unpublished studies testing computer-based interventions.

METHODS

Meta-analytic techniques were used to compute and aggregate effect sizes for 12 randomized controlled trials that met inclusion criteria. Variables that had the potential to moderate intervention efficacy were also tested.

RESULTS

The overall mean weighted effect size for condom use was d = 0.259 (95% confidence interval = 0.201, 0.317; Z = 8.74, P < 0.001; N = 4639), indicating a statistically significant impact of the interventions. This effect size compares favorably to previously tested interventions delivered by human facilitators. Statistically significant effect sizes were also found for frequency of sexual behavior, number of partners, and incident sexually transmitted diseases. In addition, interventions were significantly more efficacious when they were directed at men or women (versus mixed sex groups), utilized individualized tailoring, used a Stages of Change model, and had more intervention sessions.

CONCLUSION

Computer technology-based HIV prevention interventions have similar efficacy to more traditional human-delivered interventions. Given their low cost to deliver, ability to customize intervention content, and flexible dissemination channels, they hold much promise for the future of HIV prevention.

Gay men who engage in substance use and sexual risk behaviour: a dual-risk group with unique characteristics

'Recreational' substances used among men having sex with men, and their association with risky unprotected anal intercourse (RUAI) were examined--for the first time in Israel--in an internet-based questionnaire assessing knowledge, practices and motivation. Between March and May 2005, 2873 participants completed the entire questionnaire. Of the total, 669 (23%) reported RUAI during the last six months, and 1319 (46%) used substances during sex. Use of substance was significantly higher among those performing RUAI than those who did not (31.5% versus 26.4%, P=0.03). Involvement in both substance use and RUAI was reported by 366 participants (13%). HIV rates were higher in this dual-risk group (P<0.01), and individuals reported more partners in the last six months than those not part of this dual risk (11.6 versus 8.2, P=0.02). In multivariate analyses, Tel-Aviv residency, lower education, performing receptive RUAI, misperception of HIV transmission and limited negotiation skills were positively associated with this dual-risk behaviour.

Parent-focused child maltreatment prevention: improving assessment, intervention, and dissemination with technology

The goal of this article is to examine how technology has been and can be utilized to enhance parent-focused child maltreatment (CM) prevention efforts. The authors begin with a brief discussion of the current state of the CM prevention field. In the sections that follow, they review studies that have examined the use of technology across three facets of prevention: identification of CM, administration/augmentation of CM prevention programs, and broad dissemination and implementation of evidenced-based CM prevention programs. They conclude with a discussion of limitations and problems related to the use of technology as a tool to enhance CM prevention and future directions.

Internet based HIV prevention research targeting rural MSM: feasibility, acceptability, and preliminary efficacy

Internet delivered primary prevention interventions for HIV risk reduction present significant challenges. Changing lifestyle behaviors, such as beginning to use condoms, is difficult and men seeking dates on line may want to avoid thinking about HIV risk which may lead to low initiation and high dropout rates. Many Internet delivered HIV risk reduction programs have mimicked face-to-face outreach programs, failing to take advantage of the Internet's capabilities or did not conduct evaluation. This study focuses on examining the feasibility, acceptability, and efficacy of an Internet delivered HIV risk reduction program for rural men who have sex with men (MSM). The program included online recruiting, three intervention modules, each with two sessions, online questionnaires. The intervention was developed based on iterative research and the Information-Motivation-Behavioral skills model. Participants (N = 475) were randomly assigned to one of six module orders and data were collected automatically at pre-test and after each module. Data supports the feasibility and acceptability of the program as demonstrated by good retention and rapid program completion. Knowledge, self-efficacy, outcome expectancies and motivation increase in a dose response fashion. Post-intervention behavior changes included reduced anal sex and significant increases in condom use. Limitations include a short follow-up period, a predominantly young white rural sample, and the lack of an attention control. Overall the results of the study provide support for the efficacy of Internet-based interventions to reduce risk of HIV infection. Results also support traditional research methods to evaluate HIV prevention programs delivered exclusively through the Internet.

Seeking sexual partners on the internet: a marker for risky sexual behaviour in men who have sex with men

OBJECTIVE

In order to generate a generalizable estimate regarding risk for STI and HIV acquisition in men who have sex with men (MSM) who seek partners on the internet, we examined the sexual practices of MSM who seek partners on the internet compared to MSM who do not, using a community-based sample of MSM from British Columbia.

METHODS

'Sex Now', a questionnaire that was developed to examine trends in sexual behaviour in gay men, was offered to men attending Gay Pride events throughout the province of British Columbia, Canada between May and August 2004. Logistic regression analysis was used to model the association between seeking sexual partners online and other variables of interest, using odds ratio as the measure of association.

RESULTS

Of the 2,312 MSM who completed the survey, 766 (33.1%) had used the internet to find a partner in the past year. In logistic regression analyses, MSM who found partners on the internet were more likely to have had more than 10 sexual partners in the past year (overall, insertive and receptive), and to engage in sexual activities in public venues. They were also more likely to agree with the statement "I think most guys in relationships have condom-free sex." MSM who sought partners on the net were more likely to be from specific geographic regions, including non-urban regions. Demographic characteristics, HIV status, and use of drugs were not significantly different between men who found partners on the internet and those who did not in multivariable modeling.

DISCUSSION

MSM who sought to meet partners online had significantly more sexual partners, were more likely to be from specific geographic regions of the province and to have participated in seeking sexual partners in venues known to be associated with HIV and STI acquisition. This study confirms from a community-based sample of MSM that programming for prevention and treatment of HIV and STI need to be available and offered in the cyber setting, to ensure effective messaging and interventions reach this population.

Current trends in Internet- and cell phone-based HIV prevention and intervention programs

As the reach of the Internet and cell phones increases, their use as health intervention and prevention tools has been increasingly researched. To identify recent advances in technology-based HIV prevention and intervention research, we conducted a literature search in the Spring of 2007. Only a handful of articles have been published in the last year describing evaluations of technology-based HIV programs. Nonetheless, many programs have recently been funded and are being developed or imminently evaluated. Results to date suggest the Internet and cell phones are feasible technologies to deliver HIV prevention and intervention programs for some target populations. Opportunities for future research are identified, including the development of programs for populations other than men who have sex with men who also are at risk for HIV (eg, adolescents, elderly), the integration of advances from other fields, examination of the potential for using text messaging to affect HIV behavior change, and applications of Internet-based programs in developing countries.

Using e-mail to notify pseudonymous e-mail sexual partners

OBJECTIVE

Quantify the factors associated with reporting sexual partners only known by, or able to be contacted by, an e-mail address (pseudonymous partners) and evaluate the efforts of provider partner notification when only an e-mail address was available.

STUDY DESIGN

Persons with pseudonymous e-mail sexual partners were compared with unmatched controls. Associations were quantified by odds ratios and the effectiveness of provider partner notification attempts was assessed by comparison of outcomes of pseudonymous e-mail sexual partners and sexual partners with traditional contact information.

RESULTS

Factors associated with having pseudonymous e-mail sexual partners included: male sex, white non-Hispanic, history of prior sexually transmitted diseases, multiple sexual partners, and reporting male-to-male sexual contact. Efforts at provider partner notification via e-mail were successful with 49.7% of pseudonymous partners notified and 40.1% evaluated.

CONCLUSIONS

Internet-based forms of communications can be utilized as means to contact and identify risk partners. If this avenue is not utilized, public health agencies may be unable to intervene with a potentially growing percentage of at-risk persons.

Moderating effects of age on the alcohol and sexual risk taking association: an online daily diary study of men who have sex with men

Men who have sex with men (MSM) account for the majority of HIV/AIDS diagnoses and data suggest infection rates are rising. Identification of factors that increase the risk of infection is key to the development of effective prevention programs. Previous research has been inconsistent regarding the link between alcohol consumption and sexual risk taking among MSM. Daily reports of alcohol consumption and sexual behavior were completed for up to 30 days by 143 HIV negative MSM recruited online. This resulted in 2,887 daily reports of number of sex partners and 549 episodes of sex. Independent variables included age, number of standard drinks consumed, and partner type. Outcome variables included sex with a partner, a composite sexual risk variable, and unprotected anal intercourse (UAI). Alcohol consumption significantly increased the odds of having sex and had a significant positive association with the sexual risk composite variable. Age was a significant moderator of the association between alcohol consumption and sexual risk taking, with the effects of alcohol increasing with age. For example, at the 75%tile of age (37 years old), the odds of UAI increase from approximately 0.2 to 0.35 as the number of alcoholic drinks increases from zero to seven. Partner type did not have significant effects. Daily reports of alcohol consumption had a significant within-person association with sexual risk behaviors, particularly among older MSM. Findings highlight the importance of measuring individual differences as moderators of the association between alcohol and risky sexual behavior.

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.

Partner notification for sexually transmitted diseases in Peru: knowledge, attitudes, and practices in a high-risk community

OBJECTIVES

Notification and treatment of sex partners after diagnosis of a sexually transmitted disease (STD) is essential to reduce reinfection and further transmission.

GOAL

The goal of this study was to determine the prevalence of partner notification and subsequent health-seeking behavior in a high-risk population in Lima, Peru.

STUDY DESIGN

STD-infected participants of an HIV/STD prevention trial completed a questionnaire concerning partner notification.

RESULTS

Of the 502 STD-positive subjects, 287 completed the survey. Among survey participants, 65% informed their primary partner and 10.5% informed casual or anonymous partners. Reasons for failure to notify varied by partner type and included not understanding the importance of partner notification, embarrassment, fear of rejection, and inability to locate the partner. When notified, approximately one third of all partners sought medical attention.

CONCLUSIONS

Partner notification in Peru is limited by relationship dynamics, social stigma, and limited contact information. Interventions could emphasize the importance of notification, improvement of communication skills, and introduce contact tracing programs (including Internet-based systems) and expedited partner therapy.

Thinking about "Think Again" in Canada: assessing a social marketing HIV/AIDS prevention campaign

The Canadian "Think Again" social marketing HIV/AIDS prevention campaign, adapted from an American effort, encourages gay men to rethink their assumptions about their partners' HIV statuses and the risks of unsafe sex with them. To improve future efforts, existing HIV/AIDS prevention initiatives require critical reflection. While a formal evaluation of this campaign has been carried out elsewhere, here we use the campaign as a social marketing case study to illustrate its strengths and weaknesses, as a learning tool for other campaigns. After describing the campaign and its key results, we assess how it utilized central tenets of the social marketing process, such as formative research and the marketing mix. We then speak to the importance of theoretical influence in campaign design and the need to account for social-contextual factors in safer sex decision making. We conclude with a summary of the lessons learned from the assessment of this campaign.

The resurgence of syphilis among men who have sex with men

PURPOSE OF REVIEW

To identify recent progress and emerging problems in addressing syphilis among men who have sex with men.

RECENT FINDINGS

A resurgence of syphilis has occurred among men who have sex with men in many developed countries. Infection has been associated with HIV coinfection, multiple partners, and recreational drug use. Unlike HIV, oral sex appears to be a common route of syphilis transmission. Many prevention approaches have shown, at best, modest success. Variable clinical presentation and potentially inconclusive lab tests make diagnosis confusing.

SUMMARY

As the infection remains relatively rare, clinicians treating men who have sex with men should maintain a high index of suspicion for syphilis lesions, and should screen their sexually active patients for latent disease. Debates about syphilis control and treatment continue. The clinical manifestations, serologic responses, efficacy of treatment, and complications of syphilis have always been complicated. HIV coinfection adds to the confusion.

Syphilis and HIV infection: an update

The striking increase in the prevalence of concordant human immunodeficiency virus (HIV) infection and syphilis observed by clinicians and public health officers over the past decade has renewed interest in the subject. Although the effect of HIV infection on the natural history of syphilis has been known for a long time, it was not until recently that several studies documented that syphilis may also impact the course of HIV infection. Despite an improved understanding of the interaction of these 2 conditions, many controversies still exist. In this article, we focus on the most recent literature describing the epidemiology, clinical manifestations, and treatment of syphilis in the context of HIV infection.

Perceptions of health and self-care learning needs of outpatients with HIV/AIDS

Health promotion increases healthy behaviors, enhances health status, and decreases health care costs of chronically ill persons. As HIV has become a chronic illness, many HIV-positive persons may have health learning needs that affect their behaviors, health status, and health care costs. Health learning needs may be general or HIV specific. Social stigma may affect learning resource usage. We used Pender's Health Promotion Model and community-based health promotion principles as theoretical underpinnings for an exploratory study of perceived health and self-care learning needs, barriers, and preferred learning modalities of outpatients with HIV/AIDS. A nonrandom sample of 151 adults completed a researcher-designed self-report survey. Most (97%) expressed interest in health and self-care. Many identified multiple topics, learning barriers, and preferred learning modalities. A statistically significant difference (p=.027) was noted in communication needs of participants diagnosed with HIV versus AIDS. Findings have led to practice changes, health promotion activities, and further research.

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.

Rapid tests for sexually transmitted infections (STIs): the way forward

In the developing world, laboratory services for sexually transmitted infections (STIs) are either not available, or where limited services are available, patients may not be able to pay for or physically access those services. Despite the existence of national policy for antenatal screening to prevent congenital syphilis and substantial evidence that antenatal screening is cost-effective, implementation of syphilis screening programmes remains unacceptably low because of lack of screening tools that can be used in primary health care settings. The World Health Organization Sexually Transmitted Diseases Diagnostics Initiative (SDI) has developed the ASSURED criteria as a benchmark to decide if tests address disease control needs: Affordable, Sensitive, Specific, User-friendly, Rapid and robust, Equipment-free and Deliverable to end-users. Rapid syphilis tests that can be used with whole blood approach the ASSURED criteria and can now be deployed in areas where no previous screening has been possible. Although rapid tests for chlamydia and gonorrhoea lack sensitivity, more tests are in development. The way forward for STI diagnostics requires a continuing quest for ASSURED tests, the development of a road map for test introduction, sustainable programmes for quality assurance, and the creation of a robust infrastructure linked to HIV prevention that ensures sustainability of STI control efforts that includes viral STIs.

Adolescents and the Internet: health and sexuality information

PURPOSE OF REVIEW

Adolescents are known to be frequent users of the Internet, but less is known about the frequency and nature of their searches for information about health and sexuality. In theory, the Internet offers adolescents unprecedented access to such information in a convenient and confidential way. In turn, this information may help them to seek medical care or advice. This article reviews new research relating to adolescents' uses of the Internet for health and sexuality information, including contextual adult population studies.

RECENT FINDINGS

Adolescents are using the Internet in order to find health information on a range of subjects. Search engines are the primary strategy for such searches. The quality of the online experience is often limited by health/online literacy skills. The only reference to adolescents' quests for online information about sexuality was that they frequently sought this information from a Web site created primarily to provide information about sexually transmitted diseases.

SUMMARY

Empirical research with adolescents on this subject is scarce. More research is needed regarding issues such as the impact of software filters on ability to access health information and the medium's potential to help and harm adolescents.
