Social networking smartphone applications and sexual health outcomes among men who have sex with men

HIV Risk Behaviors and the Use of Geosocial Networking Dating Apps among Men Who have Sex with Men and Transgender Women in Lima, Peru: a Cross-Sectional Study

Geosocial networking dating apps (GSN apps) are an increasingly widespread technology used by populations throughout the world to facilitate sexual encounters. Studies from a variety of settings suggest a possible association between GSN app use and HIV risk behaviors, including among sexual and gender minority populations such as men who have sex with men (MSM) and transgender women (TW). However, it remains unclear to what extent GSN apps play a causal role. We explored the relationship between GSN app use and sexual risk behaviors among MSM and TW in Lima, Peru by analyzing data from a multi-site cross-sectional survey assessing both general and partner-specific sexual behaviors. We performed bivariate analysis to estimate the association of GSN app use with different individual and partner-specific factors, then fit multivariable regression models adjusting for age and education. Among 741 total participants (698 MSM, 43 TW), 64% met at least one sex partner in the prior three months using a GSN app. GSN app users were significantly more likely to report engaging in HIV risk behaviors in general, including condomless receptive anal sex, group sex, transactional sex, and sex under the influence of alcohol or drugs. Having condomless anal sex with a given partner was not associated with meeting that partner via GSN app. These findings highlight GSN app users as a particularly vulnerable subpopulation among MSM and TW in Lima. GSN apps could provide a useful vehicle for targeted HIV prevention efforts for priority populations in Peru.

How LGBTQ+ Young Adults Navigate Personal Risk in App-Based Hookups: The Safety Spectrum Theory

Research on hooking up is rife with examinations of risky sexual health practices among LGBTQ+ young adults; yet, little has been written about the personal safety practices for this population. This omission is notable because safety practices can enhance the notable positive outcomes related to hooking up. Drawing on one-on-one interviews with 50 LGBTQ+ young adults (20 cismen, 20 ciswomen, two transmen, and eight others) in British Columbia, California, and Connecticut, we developed the safety spectrum theory, which used a spectral measurement to assess how LGBTQ+ young adults negotiate safety practices and implement safety rules. This spectrum was then applied to a three-step sequence of application (app)-based hookup rituals: online initiation, pre-meeting preparation, and in-person meetup. Results indicated that safety strategies may be dictated by situational factors, where individuals adapt to varying circumstances to be more in control of personal safety when hooking up. We further identified that participants move across the spectrum depending upon contextual factors, such as the gender of the potential hookup partner. This work suggests that LGBTQ+ young adults are mindful of their personal safety and deserve more credit than previously attributed in queer and sexual health research. From these findings, we provide evidence-based recommendations to make dating/hookup apps and public health campaigns more effective at mitigating hookup-related risks.

Young Men Who Have Sex With Men and Substance Use: A Comparison of Venue-Based Sampling and Geosocial Networking Application Sampling

To compare the demographics, sexual risk behaviors, and substance use characteristics of two probability samples of young men who have sex with men (YMSM): one recruited using a geosocial networking application (GSNA) and one recruited using venues. In 2017 and 2018, a cross-sectional online survey was utilized with a sample of 122 YMSM recruited in Los Angeles, CA. Recruitment procedures included both venue-based (n = 68) and GSNA-based probability sampling (n = 54). Sample substance use, sexual risk behaviors (e.g., unprotected sex at last encounter), and demographics were compared using chi-square tests and t-tests. The samples significantly differed in demographics characteristics (e.g., race, education, employment, outness). Samples did not significantly differ in sexual risk variables. Regressions indicated significant differences (higher in the venue sample) in substance use (marijuana, prescription drugs, alcohol, and poppers) between the two samples. Results indicate that recruitment method impacts demographics and substance use prevalence levels for YMSM. GSNA- based recruitment appears to recruit samples from a broader range of social demographics. GSNA-based methods may be especially applicable to areas in which venues are not readily accessible (e.g., rural areas), allowing social research with the most marginalized sexual minority populations.

"I Assumed that He Knows Because He's Seen My Profile": HIV Status Disclosure and Condom Use Decisions Among Men who have Sex with Men (MSM) Using Hookup Apps and Websites

In the present study, we sought to better understand how MSM make decisions about HIV disclosure when using hook-up apps/websites and how these decisions relate to condom use during app/website-facilitated sexual encounters. Semi-structured interviews were conducted with 60 MSM (30% living with HIV) who had used hook-up apps and websites to meet sexual partners within the past three months. Results demonstrated a variety of approaches to HIV status disclosure. Some men reported usually discussing HIV status, but others discussed HIV status selectively (e.g., only when asked, when a relationship became more serious). Some men reported that listing one's status in a profile precluded the need to discuss it further. Others noted that leaving an HIV status blank "hinted" at their own or others' HIV positive or negative status. These approaches were closely linked to decisions about condom use. Many men reported serosorting based on inferences or assumptions about partners' HIV status. Together, results highlighted potential gaps in communication that can lead to faulty assumptions about HIV status and subsequent serodiscordant condomless sex and suggest that interventions that promote HIV status disclosure address these potential faulty assumptions.

Safe on Blued? A Qualitative Exploration of Sex, Risk, and Stigma on a Gay Social Application in China

Introduction

Mobile dating apps emerged with the development of technology, for example, Blued in China, becoming a new risk field for gay men in the AIDS era. Users use social apps to chat online and date offline to achieve the satisfaction of lust or sexual practice, but the risk of AID looms over the whole process of using apps.

Methods

Nineteen interviewees were invited to participate in this study, which included gay men who were using or had used Blued. The content of the semi-structured interviews focused on the relationship between gay social apps and HIV risk.

Results

The study finds Blued interweaved with sex, risk, and stigma. Blued is sexualized due to sexual intentions and practices. There is also a sexual stratification of risk with Blued and its users based on socioeconomic factors. Users experience a dilemma between pursuing sex while being concerned about latent risk within a context of stigmatization.

Conclusions

Blued is sexualized in terms of the process of stimulating sexual gratification and facilitating sexual practices. The experience of Blued is an example of sexual stratification, and a structure of desire based on app users and app uses. Furthermore, the social stigma against men who have sex with men is transferred to Blued, which bears the stigma of "AIDS-Blued" with a dual stigma-HIV-related and homosexual stigma. However, with the authorized approval of Blued in public health, Blued could play an essential role in HIV/AIDS prevention and control.

Gay App Use, Sexuality Traits, and High-Risk Sexual Behaviors Among Men Who Have Sex With Men in China: Mediation Analysis

BACKGROUND

Gay geosocial networking apps, also known as "gay apps," have gained increasing popularity in the men who have sex with men (MSM) community. Certain sexuality traits and gay app use are both associated with high-risk sexual behaviors among MSM. However, little is known about the underlying mechanism of such relationships.

OBJECTIVE

Based on the uses and gratifications theory, this study aimed to test the mediation effect of gay app use on the relationship between sexuality traits (sexual compulsivity and sexual sensation seeking) and high-risk sexual behaviors (multiple sexual partners and unprotected anal intercourse) among MSM.

METHODS

A cross-sectional, multicenter study was conducted in Wuhan and Changsha, China, from August to October 2020. A representative sample of 402 MSM was recruited through respondent-driven sampling. A self-administered web-based structured questionnaire was used to collect data on sociodemographic information, high-risk sexual behaviors, gay app use, sexual compulsivity, and sexual sensation seeking. Path analysis was conducted to assess the mediation effect.

RESULTS

Our study revealed that 67.42% (n=271) of MSM used gay apps for seeking potential sexual partners, with 37.06% (n=149) of them engaging in unprotected anal intercourse, and 45.42% (n=218) of them having multiple sexual partners. Of the participants, 17.16% (n=69) reported significant sexual compulsivity, while 29.10% (n=117) reported significant sexual sensation seeking. Notably, gay app usage partially mediated the relationship between sexual compulsivity and multiple sexual partners but fully mediated the relationship between sexual compulsivity and unprotected anal intercourse. Furthermore, gay app usage partially mediated the relationship between sexual sensation seeking and multiple sexual partners but fully mediated the relationship between sexual sensation seeking and unprotected anal intercourse.

CONCLUSIONS

High-risk sexual behaviors are common among MSM. Most MSM rely on gay apps to find sexual partners, which, when combined with higher levels of sexual compulsivity and sexual sensation seeking, can increase the likelihood of engaging in high-risk sexual behaviors. Therefore, interventions aimed at reducing these behaviors among MSM should focus on addressing the use of gay apps, while also considering the influence of their sexuality traits on gay app use.

College Students' Experiences of Dating App Facilitated Sexual Violence and Associations with Mental Health Symptoms and Well-Being

Dating app facilitated sexual violence (DAFSV) includes behaviors such as unwanted sexual comments/harassment, unsolicited sexual photos, and gender/sexuality-based harassment - and could extend to sexual violence when meeting partners face-to-face. The effects of sexual violence on mental health are well-established; however, research on DAFSV has been limited. The goal of the current study was to understand college students' experiences of DAFSV and investigate cross-sectional associations with indicators of mental health (i.e. depression and anxiety symptoms) and well-being (i.e. self-esteem, loneliness, perceived control). Participants were college students in the United States who used dating apps (N = 277) and identified primarily as women (64.6%) and heterosexual/straight (74.0%). Most participants (88.4%) self-reported at least one instance of DAFSV. Women (vs. men) and sexual minority (vs. heterosexual/straight) individuals experienced more frequent DAFSV. Regression analyses indicated that DAFSV frequency was associated with higher depression and anxiety symptoms, higher loneliness, lower self-esteem, and lower perceived control. This study highlights the importance of DAFSV for a broad range of well-being indicators. Given that dating apps are one of the most common means of meeting partners, research is needed to better understand these initial interactions, prevent DAFSV from occurring, and mitigate the impact of DAFSV on health outcomes.

Effect of e-health interventions on HIV prevention: a protocol of systematic review and meta-analysis

BACKGROUND

Global epidemiological data indicates that despite implementation of multiple interventions and significant financial investment, the HIV/AIDS epidemic remained inadequately controlled as of 2020. E-health presents a novel approach in delivering health information and health care and has gained popularity in HIV prevention worldwide. However, evidence on the effectiveness of e-health interventions on HIV prevention among diverse populations remains inadequate. Our study aims to systematically evaluate the effectiveness of varying e-health interventions on HIV prevention, with the objective of providing data support and guidance for the development of future e-health HIV intervention strategies.

METHODS

A systematic search of electronic English databases, including MEDLINE through PubMed, Embase, Scopus, and Web of Science, along with three Chinese databases, including National Knowledge Infrastructure (CNKI), Chinese Wanfang Digital Periodicals (WANFANG), and Chinese Science and Technology Periodicals (VIP) database, will be conducted for the period of 1 January 1980 to 31 December 2022. Additionally, gray literature and unpublished trials in trial registers will be searched. Studies aimed at HIV prevention through e-health interventions, with full-text publications available in either English or Chinese, will be included. Study types will be limited to RCT, cluster RCT, and quasi-experiment study. The risk of bias in individual studies will be assessed following the guideline highlighted by the Cochrane Handbook for Systematic Reviews of Interventions. The outcomes will cover cognitive, behavioral, psychological, management, and biological measures of individuals involved in e-health interventions. The quality of evidence will be assessed by the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. Ultimately, a systematic review with meta-analysis will be conducted to compare the effectiveness of e-health interventions among diverse populations.

DISCUSSION

This systematic review seeks to establish novel insights into the effectiveness of e-health interventions in diverse populations worldwide. It will inform the design and use of e-health interventions to optimize HIV-related strategies.

Geosocial networking mobile applications use and HIV and other sexually transmitted infections among men who have sex with men in Southern China: A cross-sectional study

Introduction

Men who have sex with men (MSM) are increasingly using geosocial networking (GSN) mobile applications (apps) to socialize in the community. Our study aimed to compare sexual behaviors between app-using MSM (app users) and non-app-using MSM (non-app users), and evaluate the association between app use and sexually transmitted infections (STIs).

Methods

Eligible MSM were recruited from January to August 2017 in three metropolitan cities: Guangzhou, Shenzhen and Wuxi. A self-completed tablet-based questionnaire was collected about socio-demographic characteristics, sexual behaviors and app use. Blood samples were collected to test for HIV and syphilis. Rectal swabs taken by nurses and urine samples taken by participants themselves were collected to test for gonorrhea and chlamydia. Anogenital warts were checked by a clinician. Chi square tests and logistic regression were used to compare the prevalence of STIs and the characteristics between app users and non-app users.

Results

A total of 572 MSM were included in our analysis, 59.9, 25.7, and 23.4% MSM were recruited from Guangzhou, Shenzhen, and Wuxi, respectively. The majority of participants were 20-29 years old (61.7%). 89.0% of MSM had ever used at least one GSN app, and 63.8% MSM had anal intercourse (AI) partners found via apps. Among app users, 62.7% spent <30 min on apps per day on average in the past 6 months. Compared with non-app users, app users were more likely to have an education level of college and above [adjusted OR (AOR) 3.36, 95% confidence interval (CI) 1.65-7.03], have regular sex partners (2.40, 1.16-5.19), have two or more casual sex partners (2-5: 2.90, 1.21-6.90; ≥6: 13.91, 3.13-82.90), have condomless anal intercourse (CAI) with casual sex partners in the past 6 months (2.50, 1.28-5.04), do not know their last sex partners' HIV status (2.16, 1.13-4.21), have tested for HIV in the past year (2.09, 1.07-4.09) and be circumcised (4.07, 1.29-18.42). Prevalence of HIV (8.3 vs. 7.9%, P = 0.93), syphilis (6.9 vs. 11.1%, P = 0.34), gonorrhea (5.1 vs. 6.3%, P = 0.90), chlamydia (18.5 vs. 12.7%, P = 0.36), and anogenital warts (4.9 vs. 4.8%, P = 1.00) were similar between app users and non-app users.

Conclusions

GSN app users were more likely to have high-risk sexual behaviors, but the prevalence of HIV and other STIs were similar to non-app users. Longitudinal studies comparing the incidence of HIV/STIs between long-term app users and non-app users may be necessary to clarify the impact of app use on HIV/STIs risk.

Validation of the Polish Problematic Tinder Use Scale and Its Relationship with Safe Sex Behaviors

INTRODUCTION

Online dating is a common phenomenon. The manageability and access of the application allows people to quickly reach many potential partners, which can increase risky sexual behaviors. The Problematic Tinder Use Scale (PTUS) was developed and validated in a Polish population by analyzing the reliability, validity, and factor structure of the responses given by Polish-speaking participants.

METHODS

Two samples of adult Tinder users were recruited online. The first study aimed to perform the reliability coefficient Cronbach's, interrater analysis, exploratory, and confirmatory factor analysis. The second sample was recruited to investigate the factor structure by combining it with the Safe Sex Behavior Questionnaire (SSBQ). The sociodemographic data, such as hours of use and number of dates, were also investigated.

RESULTS

The Polish participants' responses to the PTUS (sample 1: N = 271, sample 2: N = 162) revealed the one-factor structure of the tool. The reliability of the measurement was α = 0.80. The construct validity was confirmed. The results showed a significant, negative, and weak correlation between the PTUS and SSBQ scores and their subscales: risky sexual behaviors (r = -0.18), condom use (r = -0.22), and avoidance of body fluids (r = -0.17). Moreover, the number of partners met in the real world had a statistically significant, moderate relationship with the PTUS scores.

CONCLUSIONS

The PTUS measurement is valid and reliable for the Polish population. The findings highlight the need for harm prevention strategies related to potentially addictive Tinder use, as well as the possible risky sexual behaviors associated with dating app use.

Examine the associations between smartphone hookup application uses and sexual health and relationship outcomes among college students

Objective: Hookup apps, such as Tinder, have become vastly popular among college students, and hookup culture has become more normatively acceptable. The current study seeks to understand the associations of hookup app uses and outcome variables including sexual attitudes, relationship turbulences, and risky sexual behaviors. Participants and Methods: The current study conducted an online cross-sectional survey among participants (n = 654) from a large public university. Results: The results showed that hookup app users reported significantly more favorable attitudes toward sexual permissiveness and instrumentality, less favorable attitudes toward birth control, more relationship anxiety, and more relationship avoidance, compared to nonusers. Furthermore, structural equation modeling (SEM) revealed that more hookup app uses were associated with more favorable attitudes toward sexual permissiveness and instrumentality, more risky sex, and higher relationship turbulence. Conclusion: The practical implications and suggestions for future research were discussed.

Factors associated to HIV prevalence among adolescent men who have sex with men in Salvador, Bahia State, Brazil: baseline data from the PrEP1519 cohort

Adolescent men who have sex with men (AMSM) are at a heightened vulnerability for human immunodeficiency virus (HIV). This study aimed to estimate the prevalence of HIV and associated individual, social, and programmatic factors among AMSM in Salvador, Bahia State, Brazil. This is a cross-sectional study which analyzed baseline data from the PrEP1519 cohort in Salvador. Descriptive, bivariate, and multivariate analyses were conducted using the dimensions of vulnerability to HIV as hierarchical levels of analysis. Logistic regression models were used to estimate the odds ratios (OR) of the association between predictor variables and HIV infection. The prevalence of HIV infection among the 288 AMSM recruited to the project was 5.9% (95%CI: 3.7-9.3). Adjusted analysis showed a statistically significant association between self-identifying as a sex worker (OR = 3.74, 95%CI: 1.03-13.60) and HIV infection. Other associations with borderline statistical significance were the use of application programs to find sexual partners (OR = 3.30, 95%CI: 0.98-11.04), low schooling level (OR = 3.59, 95%CI: 0.96-13.41), failing to be hired or being dismissed from a job because of sexual orientation (OR = 2.88, 95%CI: 0.89-9.28), and not using health services as a usual source of care (OR = 3.14, 95%CI: 0.97-10.17). We found a high HIV prevalence among AMSM in Salvador. Furthermore, our study found that individual, social, and programmatic factors were associated with HIV infection among these AMSM. We recommend intensifying HIV combined-prevention activities for AMSM.

Men who have sex with men: An approach to social network analysis

BACKGROUND

Dating apps for men who have sex with men (MSM) have favored unprotected sexual encounters; other unsafe practices, including drug use, are widespread. No evidence is available from the perspective of the structure of their relationships, a personal aspect included in all nursing meta-paradigms.

AIM

To study the structure of MSM networks through dating and contact applications and this relationship to risky sexual activities such as condom use, chemsex (sex while using drug), and group sex.

DESIGN

Descriptive cross-sectional study.

SAMPLE

A total of 32 MSM participants from Madrid (Spain).

MEASUREMENTS

Socio-demographic and structural variables with Social Network Analysis (SNA) metrics. Data on condom use, drug use during encounters, and group sex were included.

RESULTS

Twenty-five percent of respondents practiced chemsex, and 75% of these used poppers. MSM with higher socioeconomic status participated in group sex sessions more frequently than those with lower socioeconomics. Within the network analysis, the relationships strong showed greater ease in having unprotected anal intercourse.

CONCLUSION

SNA can be effective in the study of MSM sexual networks and their risk behaviors for community nurses to improve their interventions in sexual health promotion.

Is Dating App Use Driving the Number of New Sexual Partners Among Young Adults Who Date? If Not, What Is?

Dating apps have the potential to facilitate access to a large pool of potential partners. However, both popular press and sexual health experts suggest that this increased partner accessibility is responsible for recent rises in sexually transmitted infections (STIs) and for encouraging short-term relationships over long-term commitments (e.g., Bloodworth, 2021 ; Sales, 2015 ). While recent studies support the idea that dating app use is associated with a greater number of sexual partners, the process underlying this association is still unclear. The main goal of this study was to test whether the association is better explained as a methodological artifact, a self-selection bias, or an accentuation eff ect. Young Canadian adults (N = 405) completed an online survey. Results suggest that most of the association comes from a methodological artefact and that the rest can be explained by the self-selection hypothesis. Overall, the relational goal motivations of young adults and their level of sexual impulsivity seem to play a more important role in their dating outcomes than the specifi c methods that they use to meet new people.

Social networking smartphone applications and emotional health among college students: The moderating role of social support

Young people are increasingly using social networking site (SNS) smartphone applications (apps), necessitating research on the effects of such use on the users' emotional health. The present study recruited 360 college students across mainland China and recorded their smartphone usage for one week using an automatic tracking app. Surveys assessing social support perception and emotional health were subsequently conducted. The study examined the relationship between SNS smartphone app usage (frequency and duration) and emotional health, as well as the moderating role of perceived social support in SNS smartphone usage and emotional health. Among individuals with high social support, SNS smartphone use was more strongly associated with better emotional health. These results suggest conditional benefits of using SNS smartphone apps, depending on the user's perceived social support. The implications for designing and using SNS smartphone apps are also discussed.

Awareness of HIV pre-exposure prophylaxis among men who have sex with men using apps for sexual encounters in Turkiye

Background

New HIV diagnoses are rising in Turkiye. Men who have sex with men (MSM) are estimated to be the main driver of the epidemic. Pre-exposure prophylaxis (PrEP) was proven to be effective in reducing new HIV diagnoses and PrEP recently became available in Turkiye.

Objective

To assess awareness of and willingness to use PrEP and the level of off-licence use among MSM.

Methods

An anonymous self-completed questionnaire was sent out over the Hornet Gay Social Network from December 2019 to February 2020, available in Turkish and Arabic. It included 20 questions on HIV and STI testing, PrEP awareness, PrEP use, willingness to use, chemsex and sexual happiness level.

Results

Overall 4761 respondents who responded to more than 1/3 of the questions were eligible for analyses; 5.5% was Arabic speaking. The mean age was 30.5 years, 31.4% had never tested for HIV, 40.5% knew what PrEP was, the most common source of knowledge was the internet (44.5%), 2.5% (120) had used PrEP in the last 12 months and 1.7% (83) was current users. PrEP users had accessed drugs over the internet (47.6%), pharmacy (23%), and friends (13.8%). Almost 40% were willing to use PrEP in the following 6 months. Younger and Arabic speaking respondents had lower rates of HIV testing ( p = .001) and lower awareness for PrEP than comparators ( p = .004).

Conclusion

Awareness and willingness to use PrEP is high among MSM in Turkiye. The recent availability of PrEP in the country is a big step forward in terms of prevention.

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.

Elimination of HIV transmission in Japanese MSM with combination interventions

Background

Japan has a concentrated HIV epidemic, with the majority of transmission among men who have sex with men (MSM). This study aimed to explore the effect of behavioral and biomedical interventions on the HIV epidemic and forecast the time required to eliminate HIV transmission among Japanese MSM.

Methods

A deterministic compartmental model was built to estimate and forecast the HIV epidemic among Japanese MSM from 2010 to 2050. Elimination of HIV transmission among MSM was defined as incidence less than 1/1000 person-years. The time required for eliminating HIV transmission under different scenarios was calculated.

Findings

Under the current policies, HIV transmission cannot be eliminated by 2050. Both behavioral and biomedical interventions can achieve elimination of HIV among MSM by 2050 with annual number of sexual partners among high-risk MSM less than 9, or with condom use rate above 65%, or with testing and treatment rate above 80%, or with more than 10% PrEP coverage rate. Under comprehensive interventions, HIV elimination will be achieved in 2032, 2025 and 2024 using weak, moderate and strong intervention combinations, respectively.

Interpretation

Both behavioural and biomedical interventions can achieve elimination of HIV among MSM by 2050, but comprehensive interventions can accelerate the realization of this goal with higher feasibility.

Funding

This study was funded by a Health and Labor Sciences Research Grant (Research on HIV/AIDS) from The Ministry of Health Labour and Welfare (21HB0701) and National Natural Science Foundation of China (No. 81773543 and 81973150), and the KC Wong Education Foundation.

A Latent Profile Analysis of Online Dating Patterns Among Single Young Men Who Have Sex with Men

Despite the increased use of geosocial networking applications for finding sexual partners among young men who have sex with men (YMSM), few studies have examined the intricate patterns of online dating behaviors. In order to advance understanding of online dating patterns among YMSM, various factors, including how frequently and how much time is spent within partner-seeking sites, need to be examined concurrently. Therefore, we used latent profile analysis to identify online dating patterns and logistic regressions to examine their associations with sexual behaviors and relationship characteristics among single YMSM (N = 180; ages 18-24). We found three online dating patterns: discouraged users (N = 93, 52%), date seekers (N = 67, 37%), and instant lovers (N = 20, 11%). Discouraged users were less likely to seek sexual sensational activities, while date seekers were more likely to seek sexual sensational activities. Moreover, instant lovers were less likely to pursue committed romantic relationships, while they reported a higher number of condomless anal intercourse. Given that online dating patterns are not homogeneous, HIV prevention interventions may benefit from tailored approaches based on YMSM's different online dating profiles.

Key informant perspectives on sexual health services for travelling young adults: a qualitative study

Background

International travel has become increasingly popular among young adults. Young adults often engage in casual sexual relationships abroad, exhibit sexual risk behaviours and may thus be at risk of contracting sexually transmitted and blood-borne infections. Pre-travel interventions and consultations may mitigate this risk. At present, we know little about sexual health-related pre-travel interventions. The aim of this study was therefore to document key informants’ experiences, perceptions and recommendations in the context of sexual health of young adult travellers.

Methods

Key informants were professionals working in Ottawa, Canada travel clinics, travel organizations or sexual health clinics with a young adult clientele. This study used a qualitative approach and consisted of 13 in-person or Skype semi-structured interviews with key informants. Thematic content analysis was informed by a sexual health framework, with themes emerging both inductively and deductively.

Results

Sexual health was not common in pre-travel interventions described by key informants. Risk-assessment, and practical or purpose-driven pre-travel interventions were identified, resulting in risk mitigation strategies tailored to the destination region and/or mission/culture of the travel organization. Dissemination (e.g. limited time, lack of training) and uptake (e.g. young adults’ embarrassment, provider discomfort, financial constraints) barriers limited in-depth discussions of pre-travel interventions related to sexual health. Key informants acknowledged the importance of early sexual health education, and recommended ongoing, comprehensive sexual education for both youth and young adults.

Conclusion

The findings of this study suggest that more time and resources should be allocated to the topic of sexual health during pre-travel interventions with young adults. Professionals who guide and prepare young adults for travel must develop concomitant skills in sexual health promotion. Early, comprehensive sexual education is recommended to improve overall sexual health in young adults and mitigate risk behaviours during travel.

Mapping and size estimation of men who have sex with men in virtual platforms in Delhi, India

Introduction

In India, the HIV epidemic is concentrated among Key Populations (KPs), such as men who have sex with men (MSM), who bear a disproportionate burden of HIV disease. Conventional targeted interventions (TI) mitigate HIV transmission among MSM by focusing on physical hotspots. As increasingly, there is a shift within India’s MSM community to connect with sex partners online, novel approaches are needed to map virtual platforms where sexual networks are formed. The objective of this study was to estimate the number of MSM in Delhi using virtual platforms to connect for sex and to describe patterns of their use.

Methods

The study was conducted in the state of Delhi among MSM over 18 years of age who used virtual platforms to look for sexual partners. Virtual platforms were identified through community consultations. Size estimation was carried out by enumerating the number of online users, accounting for duplication across sites and time and based on interviews with 565 MSM.

Results

28,058 MSM (95% CI: range 26,455–29,817) use virtual sites to find sexual partners. We listed 14 MSM specific virtual sites, 14 general virtual sites, 19 social networking pages and 112 messenger groups, all used by MSM. Five virtual sites met feasibility criteria to be included in the virtual mapping. Of the MSM on these sites, 81% used them at night and 94% used them on Sundays, making these the peak time and day of use. Only 16% of users were aware of organizations providing HIV services and 7% were contacted by peer educators in the preceding three months. Two-fifths (42%) also visited a physical location to connect with sexual partners in the month prior to the study.

Discussion

TI programs that focus on physical hotspots do not reach the majority of MSM who use virtual sites. MSM active on virtual sites have a low awareness of HIV services. Virtual mapping and programmatic interventions to include them must be incorporated into current public health interventions to reach MSM at risk of HIV.

Geosocial networking app use associated with sexual risk behavior, but also PrEP use, among gay, bisexual, and other men who have sex with men: Cross-Sectional Web-Based Survey (Preprint)

Background

In the United States, geosocial networking (GSN) apps (ie, mobile dating apps) have become central to dating and sexual interactions in recent years. Among gay, bisexual, and other men who have sex with men (GBM), these apps play an important role in reducing barriers and facilitating partner seeking. However, despite these benefits, there are concerns that these apps may facilitate risky sexual behavior and transmission of sexually transmitted infections (STIs) among GBM.

Objective

This study aimed to examine the association between GSN app use and sexual risk in a US sample of GBM.

Methods

Using a cross-sectional design, respondents (N=223) completed a web-based survey assessing their use of GSN apps, sexual risk and protective behaviors, HIV serostatus, and previous STI diagnoses.

Results

Respondents were aged 21-78 (mean 31.90, SD 10.06) years and 69.5% (155/223) were non-Hispanic White. The sample included respondents from 40 states and the District of Columbia. Nearly half (104/223, 47%) of the participants reported using GSN apps. GSN users were more likely to report past-year condomless anal intercourse (P<.001), 3 or more sexual partners in the previous year (P<.001), and a previous STI diagnosis (P=.001) than nonusers. GSN users also reported more frequent use of recreational drugs before sex (P=.001), alcohol use before sex (P<.001), and cannabis use before sex (P=.01). Interestingly, GSN users were also more likely to report having ever taken an HIV test (P<.001) and using pre-exposure prophylaxis (P=.03). The rates of HIV seropositivity did not differ significantly between GSN users and nonusers (P=.53). Among the subset of GSN users, 38 participants reported using only GBM-specific GSN apps (eg, Grindr), whereas 27 participants reported using only sexuality nonspecific GSN apps (eg, Tinder). Exclusive users of GBM–specific apps reported more frequent recreational drug use before sex (P=.01) and were also more likely to report past-year condomless anal intercourse (P<.001), 3 or more sexual partners in the previous year (P=.004), a previous STI diagnosis (P=.002), and HIV testing (P=.003). Alcohol use before sex, cannabis use before sex, pre-exposure prophylaxis use, and HIV rates were similar between both groups (P>.11).

Conclusions

The findings suggest that GSN apps may be a useful pathway for interventions aimed at reducing STI risk in GBM. Future prospective studies should examine how risk levels change after the initiation of GSN app use.

Novel strategies for prevention and treatment of antimicrobial resistance in sexually-transmitted infections

PURPOSE OF REVIEW

Antimicrobial resistance in sexually acquired infection (STI) pathogens is an important global public health threat. There is an urgent need for novel STI treatment and prevention strategies to tackle the rising incidence of STIs in high-income settings and the static progress in low- and middle-income settings over the past decade. The purpose of this review was to describe the research outlining the emergence of resistance in common STI pathogens and new strategies for their treatment and prevention.

RECENT FINDINGS

Rates of STIs have dramatically increased over the past decade. Further, antimicrobial resistance to first-line agents among key STI pathogens continues to emerge globally. Recent findings demonstrate promising results regarding the efficacy of novel antimicrobial treatment strategies for these pathogens, including several new, repurposed and unique combinations of antimicrobials. In addition, a number of new biomedical prevention strategies, such as antibacterial mouthwash and doxycycline chemoprophylaxis, are being investigated as novel prevention strategies for bacterial STIs.

SUMMARY

Significant progress has been made in the development of novel antimicrobials for the treatment of antimicrobial-resistant sexually acquired pathogens. However, due to the rapid development of resistance to antimicrobials demonstrated by these pathogens in the past, further research and development of effective prevention strategies should be prioritized.

Correlates of Geosocial Networking Applications (GSN Apps) Usage among Gay, Bisexual, and Other Men Who Have Sex with Men in Nigeria, Africa

Geosocial networking applications (GSN apps) are widely utilized by gay, bisexual, and other men who have sex with men (GBMSM) to meet potential sexual/romantic partners, foster friendships, and build community. However, GSN apps usage has been linked to elevated levels of HIV sexual risk behavior among GBMSM. Little is known about how GSN apps can facilitate HIV sexual risk behaviors, especially among GBMSM in Africa. To fill this gap in research, the present study aimed to characterize the frequency of GSN apps usage and its association with sociodemographic characteristics, sexual health, healthcare access, psychosocial problems, and substance use in a large multicity sample of community-recruited GBMSM in Nigeria (N = 406). Bivariate and multivariable ordinal logistic regression procedures were used to examine factors associated with GSN apps usage. We found that 52.6% of participants reported recent (≤ 3 months) GSN apps use to meet sexual partners. Factors associated with increased odds of GSN apps usage included: being single, having a university degree or higher, reporting higher recent receptive anal sexual acts, being aware of PrEP, having a primary care provider, and reporting higher levels of identity concealment. HIV-related intervention delivered through GSN apps may help curb the spread of HIV among Nigerian GBMSM.

Factors Associated With Online Sex Partners Among Gay, Bisexual and Other Men Who Have Sex With Men: Results From a National Survey

BACKGROUND

Associations between online sex seeking and increased risk for sexually transmitted infections (STIs) and human immunodeficiency virus (HIV) among men who have sex with men (MSM) typically rely on convenience samples. We examined Internet and mobile app use for finding sex partners among a nationally representative sample of MSM.

METHODS

We analyzed 2011 to 2017 data from the National Survey of Family Growth, a nationally representative sample of the civilian, non-institutionalized US population (15-44 years). The analytic sample was comprised of men who reported 1 or more same-sex partners in the past year. We also assessed associations between online sex-seeking and STI risk, sexual health care behaviors, and condom use.

RESULTS

Of 13,320 male respondents, 442 (3.0%) reported sex with a man in the past year, of whom 215 (46.3%) had met a partner online. Between MSM who met partners online and those who did not, we found no differences by age, education, race/ethnicity or socioeconomic status. Men who have sex with men with online partners were more likely to identify as gay (68.4% vs 49.5%, P = 0.0124). They also reported more sex partners overall (M = 3.04 vs 1.60, P < 0.0001), and multiple insertive (46.3% vs 8.5%, P < 0.0001) and receptive (33.2% vs 15.4%, P = 0.0055) anal sex partners, in the past year. They were also more likely to receive sexual risk assessments (56.0% vs 40.4%, P = 0.0129), STI testing (57.4% vs 35.3%, P = 0.0002), and STI treatment (17.8% vs 8.7%, P = 0.0152) in the past year. We found no differences in condom use.

CONCLUSIONS

Men who have sex with men who report using online sources to find sex partners are more likely than other MSM to report behaviors that increase risk for STI/HIV but are also more likely to engage in behaviors that may mitigate further transmission, such as STI testing.

"What Are You Looking For?" Investigating the Association Between Dating App Use and Sexual Risk Behaviors

Introduction

Literature on the association between dating app use and sexual risk behaviors is still scant and inconclusive.

Aim

To investigate the association between dating app use and sexual risk behaviors, considering the role of motives for using them.

Methods

1,278 Italian respondents completed an online questionnaire assessing demographics, motives and patterns of dating app use, sexual behaviors and sexually transmitted infections (STIs) diagnoses. One-way ANOVA and Chi-squared analyses were used to investigate differences among the three subsamples (active vs former vs non-users). Multiple linear and logistic regression analyses were run to investigate the role of demographics, motives and patterns of dating app use on sexual risk taking and sexual health.

Main outcome measures

Number of protected and unprotected full sexual partners in the last year; frequency of hook-ups in the last year; STIs lifetime.

Results

Active users, even more than former app users, were more likely to report risky behaviors and STI diagnoses than non-users (χ² = 26.37, P < .001). Installing the apps to find friends or romantic partners was associated with less protected (find friends B = −0.364, P = .015; find romantic partners B = −0.300, P = .006) and unprotected (find friends B = −0.346, P = .016; find romantic partners B = −0.360, P < .001) sexual intercourses. Installing the apps to find sexual partners predicted higher odds of unprotected sexual activity (B = 0.193, P = .048), hook-ups (B = 0.496, P < .001) and STIs diagnoses (OR = 2.835, P = .025). Accessing apps more frequently and more years of usage was associated with reporting risky sexual behaviors and STI diagnoses among active users (app access frequency OR = 1.461, P = .003; usage years OR = 1.089, P = .013).

Conclusion

Installing the apps to search for sexual partners, using them at length since first installation and accessing them frequently are significant factors in influencing the association between dating app use and sexual risk behaviors.

Stewardship of global collective behavior

Collective behavior provides a framework for understanding how the actions and properties of groups emerge from the way individuals generate and share information. In humans, information flows were initially shaped by natural selection yet are increasingly structured by emerging communication technologies. Our larger, more complex social networks now transfer high-fidelity information over vast distances at low cost. The digital age and the rise of social media have accelerated changes to our social systems, with poorly understood functional consequences. This gap in our knowledge represents a principal challenge to scientific progress, democracy, and actions to address global crises. We argue that the study of collective behavior must rise to a "crisis discipline" just as medicine, conservation, and climate science have, with a focus on providing actionable insight to policymakers and regulators for the stewardship of social systems.

The Experience of Using Dating Applications for Sexual Hook-Ups: A Qualitative Exploration among HIV-Negative Men Who Have Sex With Men in Hong Kong

Men who have sex with men (MSM) use dating applications (apps) to explore various romantic and sexual relationships. This qualitative study aimed to describe HIV-negative MSM's experiences with app usage, the sexual activities arranged accordingly and their experiences in using dating apps to arrange sexual encounters. Thirty-one MSM who were sexually active and who used dating apps were recruited. Individual semi-structured interviews were conducted. Qualitative data were thematically analyzed to outline significant phenomena and perceptions. The factors associated with matching on apps included sex roles, human immunodeficiency virus serostatus and availability of a venue for meetup. Facilitated by these apps, diverse types of sexual encounters were arranged. Condoms were typically used for safer intercourse, except by people who were younger and inexperienced or when drugs were consumed before or during sex (chemsex). Extensive interest in non-penetrative sexual behaviors was expressed by our sample. Searching for post-exposure prophylaxis methods and/or sexual health screenings was common after exposure to risk of infections. Sexually abusive encounters were followed by changes in sex-searching habits and lowered trust in relationship formation. The results of this study are important for the development of appropriate interventions to promote safer sexual practices among HIV-negative MSM dating app users.

Gay and Bisexual Men's Recommendations for Effective Digital Social Marketing Campaigns to Enhance HIV Prevention and Care Continuity

Because use of geosocial-networking smartphone applications ('apps') is ubiquitous among men who have sex with men (MSM), online-to-offline service models that include advertisements on these apps may improve engagement with effective HIV prevention and treatment services. Through our formative qualitative study, we conducted individual in-depth interviews (n = 30) and focus group discussions (n = 18) with MSM in Rhode Island to develop a digital social marketing campaign aimed at increasing HIV testing, including how best to reach men by advertising on apps. Qualitative data analysis revealed that participants were frequently exposed to pop-up advertisements on apps. These advertisements are viewed as invasive and, as such, many expressed a preference for other formats (e.g., direct messages, banner advertisements). Men expressed a preference for provocative images and phrases to catch their attention followed with fact-driven messaging to motivate them to engage with services offline. Findings from this study offer several practical recommendations for developing a social marketing campaign that uses advertisements on apps to increase HIV testing among MSM, including using formats other than pop-up advertisements and pairing fact-driven messaging with eye-catching images to direct them to trusted local clinical services.

Mobile HIV Testing Through Social Networking Platforms: Comparative Study

Background

Improving HIV screening in key populations is a crucial strategy to achieve the goal of eliminating AIDS in 2030. Social networking platforms can be used to recruit high risk-taking men who have sex with men (MSM) to promote the delivery of voluntary counseling and testing (VCT) as mobile HIV testing. Therefore, client recruitment and availability of mobile HIV testing through social networking platforms requires further evaluation.

Objective

The aim of this study is to compare the effects of targeting high risk-taking MSM and HIV case finding between two mobile HIV testing recruitment approaches: through the traditional website-based approach and through social networking platforms.

Methods

A comparative study design and propensity score matching was applied. The traditional VCT model, that is, the control group, recruited MSM through a website, and a trained research assistant visited the walk-in testing station at a gay village on Friday and Saturday nights. The social networking VCT model, the experimental group, recruited MSM from social networking platforms by periodically reloading into and conducting web-based discussions on dating apps and Facebook. The participants then referred to others in their social networks via a popular messenger app in Taiwan. The test was conducted at a designated time and place during weekdays by a trained research assistant. Across both modes of contact, before the mobile HIV testing, participants needed to provide demographic characteristics and respond to a questionnaire about HIV risk-taking behaviors.

Results

We recruited 831 MSM over 6 months, with a completion rate of 8.56% (616/7200) in the traditional VCT model and 20.71% (215/1038) in the social networking VCT model. After propensity score matching, there were 215 MSM in each group (mean age 29.97, SD 7.61 years). The social networking model was more likely to reach MSM with HIV risk-taking behaviors, that is, those seeking sexual activity through social media, having multiple sexual partners and unprotected anal intercourse, having experience of recreational drug use, and never having or not regularly having an HIV test, compared with the traditional model. HIV positive rates (incidence rate ratio 3.40, 95% CI 1.089-10.584; P=.03) and clinic referral rates (incidence rate ratio 0.03, 95% CI 0.001-0.585; P=.006) were significantly higher among those in the social networking VCT model than in the traditional VCT model.

Conclusions

Through effective recruitment strategies on social networking platforms, the social networking VCT mode can be smoothly promoted, as compared with the traditional VCT model, to target high risk-taking MSM and increase testing outcomes.

Correlates of newly diagnosed HIV infection among cisgender women sex workers and transgender women sex workers in Greater Kuala Lumpur, Malaysia

Globally, cisgender women sex workers (CWSWs) and transgender women sex workers (TWSWs) experience increased vulnerabilities to HIV infection. Unfortunately, there is limited data on the drivers of HIV infection in these two understudied populations, particularly in Southeast Asia. To better understand factors associated with HIV infection, we evaluated correlates of newly diagnosed HIV infection in these two populations in Greater Kuala Lumpur, Malaysia. A total of 469 women (CWSW: n = 283; TWSW: n = 186) were included in this study. Most participants who tested HIV+ were unaware of their infection (59.6%; n = 34/57). Separate binary and multivariable logistic regressions were conducted to identify correlates of newly diagnosed HIV in CWSWs and TWSWs. Among CWSWs, Chlamydia trachomatis (aOR = 5.66; p = 0.007) and lifetime use of ecstasy/MDMA (aOR = 5.34; p = 0.03) were associated with newly diagnosed HIV, while condomless vaginal sex with clients was associated with lower likelihood of HIV infection (aOR = 0.98; p = 0.01). Among TWSWs, being single (aOR = 6.76; p = 0.03), using mobile application to solicit clients (aOR = 25.33; p = 0.006), and having C. trachomatis infection (aOR = 88.22, p = 0.02) were associated with newly diagnosed HIV. Expansion of HIV/sexually transmitted infection screening is needed to increase detection of HIV and linkage to care for sex workers. Interventions to reduce HIV infection among CWSWs and TWSWs should be tailored to these populations' unique vulnerabilities.

Characterizing substance use among men who have sex with men presenting to a sexually transmitted infection clinic

Illicit substance use poses a significant public health challenge in the United States. Certain populations are disproportionately impacted by substance use disorders. Men who have sex with men (MSM) have been shown to be three to four times more likely to report substance use compared to the general population. MSM also make up a disproportionate number of new cases of STIs. The impact of substance use disorders on STI and HIV infection risk has been well documented among this vulnerable population. Understanding the intersection of substance use and sexual risk is important to design effective interventions to reduce substance use and risk of STIs. However, little is known about the relationship between venues used to arrange sexual encounters including hook-up apps and substance use. This study describes the demographics and social network characteristics of MSM who presented to an STI clinic in Rhode Island including reported substance use and the primary hook-up venues used for meeting sexual partners. The results show that individuals using online venues to meet sexual partners were more likely to report substance use, indicating the possible utility of interventions using social media to address the unique vulnerability of STI and HIV infection for substance using MSM.

Use of Geosocial Networking Apps and HIV Risk Behavior Among Men Who Have Sex With Men: Case-Crossover Study

Background

HIV disproportionately affects men who have sex with men (MSM) in China. The HIV epidemic is largely driven by unprotected anal sex (ie, sex not protected by condoms or HIV pre-exposure prophylaxis [PrEP]). The possible association between unprotected anal sex and the use of geospatial networking apps has been the subject of scientific debate.

Objective

This study assessed whether users of a gay geospatial networking app in China were more likely to use condoms when they met their partners online versus offline. A case-crossover analysis, with each person serving as his own control, was employed to address the potential bias that men looking for sex partners through an online dating medium might have inherently different (and riskier) patterns of sexual behavior than men who do not use online dating media.

Methods

A cross-sectional survey was administered in 2018 to adult male users of Blued—a gay geospatial networking app—in Beijing, Tianjin, Sichuan, and Yunnan, China. A case-crossover analysis was conducted among 1311 MSM not taking PrEP who reported engaging in both unprotected and protected anal sex in the previous 6 months. Multivariable conditional logistic regression was used to quantify the association between where the partnership was initiated (offline or online) and the act of unprotected anal sex, controlling for other interval-level covariates. Four sensitivity analyses were conducted to assess other potential sources of bias.

Results

We identified 1311 matched instances where a person reported having both an unprotected anal sex act and a protected anal sex act in the previous 6 months. Of the most recent unprotected anal sex acts, 22.3% (292/1311), were initiated offline. Of the most recent protected anal sex acts, 16.3% (214/1311), were initiated offline. In multivariable analyses, initiating a partnership offline was positively associated with unprotected anal sex (odds ratio 2.66, 95% CI 1.84 to 3.85, P<.001) compared with initiating a partnership online. These results were robust to each of the different sensitivity analyses we conducted.

Conclusions

Among Blued users in 4 Chinese cities, men were less likely to have unprotected anal sex in partnerships that they initiated online compared with those that they initiated offline. The relationship was strong, with over 2.5 times the likelihood of engaging in unprotected anal sex in partnerships initiated offline compared with those initiated online. These findings suggest that geospatial networking apps are a proxy for, and not a cause of, high-risk behaviors for HIV infection; these platforms should be viewed as a useful venue to identify individuals at risk for HIV transmission to allow for targeted service provision.

Use of dating sites and applications by women and their risk of sexually transmitted infections: a systematic review and meta-analysis protocol

INTRODUCTION

The use of social networks has been increasing worldwide. Mobile websites and applications (apps) allow people to network more quickly and have more partners for sex. This can facilitate risky sexual behaviours, such as having multiple partners and unprotected sex, which can lead to a higher incidence of sexually transmitted infections. This systematic review/meta-analysis will assess the effects of the use of dating sites and apps by women on their level of engagement in risky sexual behaviours and their incidence of sexually transmitted infections.

METHODS AND ANALYSIS

The Cochrane Central Controlled Trials Registry, ClinicalTrials.gov, MEDLINE, Embase, SciELO, Web of Science, Scopus and Cumulative Index to Nursing & Allied Health Literature will be searched for cross-sectional studies, clinical trials and observational studies published between January 1990 and July 2020. This systematic review and meta-analysis will include studies investigating the use of mobile apps by women, risky sexual behaviour and sexually transmitted infections. The outcome will be an increase in new cases of sexually transmitted infections and HIV among women using dating sites and apps. Three independent reviewers will select the studies and extract data from the original articles. The risk of bias will be assessed using the Cochrane risk of bias tool and Risk Of Bias in Non-randomized Studies of Interventions. Data synthesis will be performed using Review Manager software (RevMan V.5.2.3). To assess heterogeneity, we will compute the I2 statistic. In addition, a quantitative synthesis will be carried out if the included studies are sufficiently homogeneous.

ETHICS AND DISSEMINATION

This study will be a review of the published data, and thus ethical approval is not required. The findings of this systematic review will be published in a peer-reviewed journal.

Threats to Mental Health Facilitated by Dating Applications Use Among Men Having Sex With Men

In the last years, dating applications (DAs) have had a significant impact on the way in which people seek sexual and romantic relationships. Social groups, such as men having sex with men (MSM), who can experience discrimination and social isolation, find DAs especially engaging and helpful in finding sexual partners. Previous studies have provided evidence showing vulnerability to mental health problems among the MSM population-these problems can be potentially facilitated by DAs use. Excessive use of DAs is associated with lower well-being and life satisfaction, depression, higher substance use, and lower sleep quality. Therefore, there is a need for a better understanding of psychological functioning and risk factors associated with the use of DAs among MSM, which we focus on in this review. We also discuss two relatively new research areas: compulsive sexual behavior disorder and chemsex, and their relation to geosocial-networking mobile technologies. Finally, we point out the limitations of available studies on the mental health of MSM using DAs and propose further research directions.

A Picture is Worth 1000 Messages: Investigating Face and Body Photos on Mobile Dating Apps for Men Who Have Sex with Men

The present study investigated the way men visually self-present on MSM-specific mobile dating app profiles, as well as the connection between visual self-presentation strategies, demographic variables, and psychosocial attitudes about masculinity and the body. In particular, emphasis was placed on two aspects of men's visual self-presentation: face-disclosure and body-disclosure. Using a selective self-presentation framework, findings indicated that the majority of men presented their face in their profile photo and that nearly one in five presented their unclothed torso. Face-disclosure was connected to higher levels of app usage, longer-term app usage, and levels of outness. The use of shirtless photos was related to age, a higher drive for muscularity, more self-perceived masculinity, and stronger anti-effeminacy attitudes. The findings are discussed in relation to both strategic self-presentation, and the distinct meanings of face and body photos within MSM online culture.

Social media recruitment for mental health research: A systematic review

BACKGROUND

Social media holds exciting promise for advancing mental health research recruitment, however, the extent and efficacy to which these platforms are currently in use are underexplored.

OBJECTIVE

A systematic review was conducted to characterize the current use and efficacy of social media in recruiting participants for mental health research.

METHOD

A literature review was performed using MEDLINE, EMBASE, and PsychINFO. Only non-duplicative manuscripts written in the English language and published between 1/1/2004-3/31/2019 were selected for further screening. Data extracted included study type and design, participant inclusion criteria, social media platform, advertising strategy, final recruited sample size, recruitment location, year, monetary incentives, comparison to other recruitment methods if performed, and final cost per participant.

RESULTS

A total of 176 unique studies that used social media for mental health research recruitment were reviewed. The majority of studies were cross-sectional (62.5%) in design and recruited adults. Facebook was overwhelmingly the recruitment platform of choice (92.6%), with the use of paid advertisements being the predominant strategy (60.8%). Of the reviewed studies, substance abuse (43.8%) and mood disorders (15.3%) were the primary subjects of investigation. In 68.3% of studies, social media recruitment performed as well as or better than traditional recruitment methods in the number and cost of final enrolled participants. The majority of studies used Facebook for recruitment at a median cost per final recruited study participant of $19.47. In 55.6% of the studies, social media recruitment was the more cost-effective recruitment method when compared to traditional methods (e.g., referrals, mailing).

CONCLUSION

Social media appears to be an effective and economical recruitment tool for mental health research. The platform raises methodological and privacy concerns not covered in current research regulations that warrant additional consideration.

'It's like getting an Uber for sex': social networking apps as spaces of risk and opportunity in the Philippines among men who have sex with men

The HIV epidemic in the Philippines has been expanding rapidly, with most newly diagnosed cases occurring among 'men who have sex with men' (MSM). New social contexts of HIV are evident in the evolving phenomenon of more MSM seeking partners online via social networking applications ('apps'). This study examines findings from a virtual ethnography of app use among MSM, focus group discussions with community-based healthcare workers, and key informant interviews with healthcare workers, policymakers and researchers in Metro Manila. We argue that participants viewed the expanding epidemic and apps as intimately linked, regarding the apps as 'risky spaces' for 'risky behaviour'. However, such narratives neglected the agentive capabilities of the apps and how they have transformed sexual practice, creating new ways of being as sexual subjects, while perpetuating old imaginaries among healthcare workers of 'hard-to-reach' populations. Such narratives of 'risk' have led to new interventions by healthcare workers on the apps, viewing these technologies as opportunities to reach more MSM for health promotion. However, the interventions have created new complexities by reconfiguring boundaries with target populations. By conducting community-based outreach through encouraging behaviour change in one-to-one interactions with app users, the potential impact of these interventions is limited.

Grindr Users Take More Risks, but Are More Open to Human Immunodeficiency Virus (HIV) Pre-exposure Prophylaxis: Could This Dating App Provide a Platform for HIV Prevention Outreach?

BACKGROUND

Technology has changed the way that men who have sex with men (MSM) seek sex. More than 60% of MSM in the United States use the internet and/or smartphone-based geospatial networking apps to find sex partners. We correlated use of the most popular app (Grindr) with sexual risk and prevention behavior among MSM.

METHODS

A nested cohort study was conducted between September 2018 and June 2019 among MSM receiving community-based human immunodeficiency virus (HIV) and sexually transmitted infection (STI) screening in central San Diego. During the testing encounter, participants were surveyed for demographics, substance use, risk behavior (previous 3 months), HIV pre-exposure prophylaxis (PrEP) use, and Grindr usage. Participants who tested negative for HIV and who were not on PrEP were offered immediate PrEP.

RESULTS

The study included 1256 MSM, 1090 of whom (86.8%) were not taking PrEP. Overall, 580 of 1256 (46%) participants indicated that they used Grindr in the previous 7 days. Grindr users reported significantly higher risk behavior (greater number of male partners and condomless sex) and were more likely to test positive for chlamydia or gonorrhea (8.6% vs 4.7% of nonusers; P = .005). Grindr users were also more likely to be on PrEP (18.7% vs 8.7% of nonusers; P < .001) and had fewer newly diagnosed HIV infections (9 vs 26 among nonusers; P = .014). Grindr users were also nearly twice as likely as nonusers to initiate PrEP (24.6% vs 14%; P < .001).

CONCLUSIONS

Given the higher risk behavior and greater acceptance of PrEP among MSM who used Grindr, Grindr may provide a useful platform to promote HIV and STI testing and increase PrEP uptake.

Dating Applications, Sexual Behaviors, and Attitudes of College Students in Brazil's Legal Amazon

Although dating applications (apps) have become popular among young adults, there is a dearth of information regarding the sexual health implications among Brazilian college students. This study examined risky sexual behavior and attitudes of dating app users, based on their sex in Brazil’s Legal Amazon. Three hundred and fifty-nine students reported their sociodemographic data, dating app use, and sexual behaviors and attitudes through self-administered questionnaires. Bivariate analyses and analysis of variance (ANOVA) with Bonferroni post-hoc tests were performed. Dating app use was reported by 238 (66.3%) subjects, most of whom had an encounter and sex with a casual partner. Women frequently requested condom use. Trust in one’s partner or having repeated encounters were the main reasons for engaging in risky sexual behavior. Men had a greater number of sexual partners and less protective attitudes. Sexual health awareness by apps was not reported by 97% of women, and most of them were not tested for sexually transmitted infections. A positive attitude toward sexual health was not a predictor of safe sex. Important similarities and differences regarding risky sexual behaviors and attitudes were observed between the sexes, many of which correlated with increased sexual vulnerability during the sexual encounters arranged through the dating apps. This cross-sectional study supports efforts on sexual health promotion and sexual education implementation in the face of growing usage of apps among young adults for sexual matters.

Geosocial Networking Application Use, Characteristics of App-Met Sexual Partners, and Sexual Behavior Among Sexual and Gender Minority Adolescents Assigned Male at Birth

Although many sexual and gender minorities (SGM) assigned male at birth (AMAB) use sexual networking applications intended for adult sexual minority men, little is known about adolescents' use of these technologies and characteristics of their online-met partners. We conducted an online survey of 219 sexually experienced SGM AMAB adolescents in the USA aged 15-17 (39.3% racial/ethnic minority; 74.9% gay; 94.1% cisgender male). Questions assessed app use patterns, partner-seeking behaviors on sexual minority male-specific apps vs. social media/other dating apps, app-met partner characteristics, and sexual behavior with app-met partners. Most (70.3%) used apps for sexual minority men, 14.6% used social media/other apps to meet partners, and 15.1% used neither. Nearly 60% of adolescents who used any type of app reported having met people from the apps in person, and nearly 90% of these reported at least one online-met sexual partner. Most partners were reportedly older than participants, and participants were more likely to report condomless receptive anal sex with older (vs. younger) online-met partners. Although partnerships were primarily sexual in nature, a minority reported friendships or serious partnerships. Meeting same-sex/gender partners via applications for adults may be common among SGM AMAB adolescents, which has implications for their sexual health and well-being.

Digital chemsex support and care: The potential of just-in-time adaptive interventions

Chemsex among gay, bisexual and other men who have sex with men (GBMSM) has received increasing attention as a public health concern in recent years. Chemsex can affect a variety of aspects of the lives of GBMSM and contribute to physical, social and emotional health burden. Starting from a continuum perspective of chemsex, rather than a binary view of problematic vs. non-problematic use, we argue that men engaging in chemsex at different points in their chemsex journey may benefit from tailored and personalized support to cope with the various and evolving challenges and concerns that may be related to their chemsex behavior. To date, interactive digital communication technologies are not much used to provide support and care for GBMSM engaging in chemsex, neither for community-based support and care nor by health services. This suggests potential for missed opportunities, as GBMSM are generally avid users of these technologies for social connections and hookups, including in relation to chemsex. Recent research has provided emerging evidence of the potential effects of so-called just in time adaptive interventions (JITAI) to provide effective support and care for a variety of health issues. JITAI hold much promise for the provision of appropriate, tailored support and care for GBMSM at different points in the chemsex journey. Co-designing JITAI with potential users and other stakeholders (co-design) is key to success. At the Institute for Tropical Medicine, in Antwerp (Belgium), we initiated the Chemified project to develop an innovative digital chemsex support and care tool for GBMSM. This project illustrates how current understanding of chemsex as a journey can be integrated with a JITAI approach and make use of co-design principles to advance the available support and care for GBMSM engaging in chemsex.

Sex-seeking mobile application use and risk behavior among men who have sex with men in Brazil

This is a cross-sectional study based on an open web survey with the primary objective to assess associations between the use of apps for seeking sex partners and vulnerabilities related to human immunodeficiency virus (HIV) acquisition among men who have sex with men (MSM) in Brazil. Participants were recruited to the study through ads posted in social media such as Twitter, Facebook, and WhatsApp. Consenting respondents completed a questionnaire on demographics, history of sexually transmitted infections (STIs), and risk behaviors and perceptions, including calculation of the Risk Behavior Score for HIV infection proposed by Rocha et al. Among the 859 participants, 714 (83.1%) reported they used apps for seeking sex partners. Use of apps for seeking sex partners was associated with high-risk behavior for HIV infection, self-reported syphilis, self-perception of HIV risk, and use of marijuana. The use of apps for seeking sex partners has rapidly become the norm for MSM in Brazil. The associations with STIs and risk behaviors should be seen as an opening to improve public health, presenting opportunities to promote knowledge, safer sex practices, and referral to HIV/STI screening and prevention interventions.

Using Digital Communication Technology to Increase HIV Testing Among Men Who Have Sex With Men and Transgender Women: Systematic Review and Meta-Analysis

BACKGROUND

HIV continues to disproportionately affect men who have sex with men (MSM) and transgender women (TW). Undiagnosed HIV is a major driver of HIV transmission rates, and increasing the uptake of regular HIV testing and facilitating timely initiation of HIV treatment is a global HIV prevention priority. However, MSM and TW experience a range of barriers that limit their access to testing and other prevention services. Given their growing ubiquity, digital communication technologies are increasingly being used to support HIV prevention efforts, and a growing number of studies have trialed the use of digital technology to promote HIV testing among MSM and TW.

OBJECTIVE

We undertook a systematic review and meta-analysis to assess the impact of digital communication technology on HIV testing uptake among MSM and TW. Subanalyses aimed to identify the features and characteristics of digital interventions associated with greater impact.

METHODS

A systematic literature review was undertaken using select databases and conference repositories. Studies describing the use of a digital technology-internet-enabled devices, including phones, tablets, and computers-to increase HIV testing uptake among MSM or TW using either randomized or observational cohort design with measurement of HIV testing rates measured pre- and postintervention, and published in English between 2010 and 2018 were included. Pooled effect estimates were calculated using a random effects meta-analysis. Subanalyses calculated effect estimates grouped by selected features of digital interventions.

RESULTS

A total of 13 randomized or observational studies were included in the final review. Digital interventions most commonly used mainstream, existing social media platforms (n=7) or promotion through online peer educators (n=5). Most interventions (n=8) were categorized as interactive and allowed user engagement and most directly facilitated testing (n=7) either by providing self-testing kits or referral to testing services. A total of 1930 participants were included across the 13 studies. HIV testing uptake among MSM and TW exposed to digital interventions was 1.5 times higher than that of unexposed MSM and TW (risk ratio [RR] 1.5; 95% CI 1.3-1.7). Subanalyses suggested an increased impact on HIV testing uptake among interventions that were delivered through mainstream social media-based platforms (RR 1.7; 95% CI 1.3-2.1), included direct facilitation of HIV testing (RR 1.6; 95% CI 1.4-1.9), were interactive (RR 1.6; 95% CI 1.4-1.8), and involved end users in the design process (RR 1.6; 95% CI 1.3-2.0).

CONCLUSIONS

These findings provide broad support for the integration of technology with existing approaches to promote and facilitate HIV testing among MSM and TW. Our findings identified key features that may be associated with greater impact on HIV testing uptake and can be used to inform future development efforts given the growing interest and application of digital technologies in HIV prevention.

Inferring Sexually Transmitted Infection Risk From Attractiveness in Online Dating Among Adolescents and Young Adults: Exploratory Study

Background

Sexually transmitted infection (STI) rates are on the rise among adolescents and young adults in the United States. With the popularity of online dating, adolescents and young adults must increasingly rely on limited cues to make initial judgments about potential sexual partners, including judgments about STI risk.

Objective

This study aimed to assess whether in the context of online dating, an attractiveness heuristic would be used for STI risk assessment. We hypothesized that consistent with research on halo effects, decision makers would judge more attractive people to be less likely to have STIs.

Methods

In a survey experiment, we asked participants to determine which individual in each of 20 sets of paired photographs was enrolled in a personals website for people with publicly disclosed STIs.

Results

Despite financial incentives for accuracy and high levels of self-confidence in their judgments, participants performed no better than chance at identifying individuals with self-reported STIs. Contrary to our hypothesis, however, more attractive people were judged as being more likely to have an STI. This relationship appears to be mediated by inferences regarding the target individual’s sexual behavior, with more attractive individuals considered to have more partners.

Conclusions

On showing adolescents and young adults photographs offering no diagnostic information about STIs, they appeared to use attractiveness as a cue for sexual risk, which was mediated by the belief that attractive individuals have more sexual opportunities. Health care providers may wish to address this heuristic process among their adolescent patients in discussions about sexual health.

Factors Associated With Increased Syphilis Screening Among People Living With Human Immunodeficiency Virus

BACKGROUND

Antiretroviral therapy effectively reduces the risk of human immunodeficiency virus transmission, but in the context of undetectable equals untransmittable and decreased condom use, rates of syphilis are increasing. In Oregon, syphilis has risen over 20-fold in the past decade, from less than 30 to approximately 600 cases annually during 2016 and 2017. Although many cases are among people living with human immunodeficiency virus infection (PLWH), screening for syphilis among PLWH is often lacking. The objective of this study was to estimate the prevalence of past-year syphilis testing among PLWH in Oregon to identify facility-level and individual-level factors associated with testing.

METHODS

We examined 2015 to 2016 Medical Monitoring Project interview and medical records data in Oregon and conducted supplemental interviews with participants' medical providers. We used generalized mixed effects models to identify factors associated with syphilis screening.

RESULTS

Sixty-nine percent of Medical Monitoring Project participants had past-year syphilis screening. Patients receiving care from facilities with written sexually transmitted infection screening policies were far more likely to be screened than those receiving care from facilities without written policies (94% vs. 43%, P < 0.001). Participants who identified as male were more likely to have been tested, even after adjusting for facility-level characteristics. Clustering within facility accounted for about 15% of the unexplained variability in the adjusted mixed effects models.

CONCLUSIONS

Written sexually transmitted infection screening policies at medical facilities appear to be an important tool for ensuring syphilis screening occurs as recommended to prevent the continued rise in syphilis.

HIV prevalence, testing and treatment among men who have sex with men through engagement in virtual sexual networks in Kenya: a cross-sectional bio-behavioural study

INTRODUCTION

In Kenya, men who have sex with men (MSM) are increasingly using virtual sites, including web-based apps, to meet sex partners. We examined HIV testing, HIV prevalence, awareness of HIV-positive status and linkage to antiretroviral therapy (ART), for HIV-positive MSM who solely met partners via physical sites (PMSM), compared with those who did so in virtual sites (either solely via virtual sites (VMSM), or via both virtual and physical sites (DMSM)).

METHODS

We conducted a cross-sectional bio-behavioural survey of 1200 MSM, 15 years and above, in three counties in Kenya between May and July 2019, using random sampling of physical and virtual sites. We classified participants as PMSM, DMSM and VMSM, based on where they met sex partners, and compared the following between groups using chi-square tests: (i) proportion tested; (ii) HIV prevalence and (iii) HIV care continuum among MSM living with HIV. We then performed multivariable logistic regression to measure independent associations between network engagement and HIV status.

RESULTS

177 (14.7%), 768 (64.0%) and 255 (21.2%), of participants were classified as PMSM, DMSM and VMSM respectively. 68.4%, 70.4% and 78.5% of PMSM, DMSM and VMSM, respectively, reported an HIV test in the previous six months. HIV prevalence was 8.5% (PMSM), 15.4% (DMSM) and 26.7% (VMSM), p < 0.001. Among those living with HIV, 46.7% (PMSM), 41.5% (DMSM) and 29.4% (VMSM) were diagnosed and aware of their status; and 40.0%, 35.6% and 26.5% were on antiretroviral treatment. After adjustment for other predictors, MSM engaged in virtual networks remained at a two to threefold higher risk of prevalent HIV: VMSM versus PMSM (adjusted odds ratio 3.88 (95% confidence interval (CI) 1.84 to 8.17) p < 0.001); DMSM versus PMSM (2.00 (95% CI 1.03 to 3.87), p = 0.040).

CONCLUSIONS

Engagement in virtual networks is associated with elevated HIV risk, irrespective of individual-level risk factors. Understanding the difference in characteristics among MSM-seeking partners in different sites will help HIV programmes to develop subpopulation-specific interventions.

Prevalence and Risk Factors for HIV Infection in a Population of Homosexual, Bisexual, and Other Men Who Have Sex with Men in the Metropolitan Region of Chile: A Re-emerging Health Problem

According to the most recent UNAIDS report, the number of new HIV infections has increased by 34% since 2010 in Chile, representing the largest increase in the Americas. The objective of this study was to identify factors associated with HIV prevalence among men who have sex with men (MSM) in the metropolitan region (MR) of Santiago, Chile. Cross-sectional study of MSM living in the MR, recruited using respondent-driven sampling (RDS). Participants were tested using Human Immunodeficiency virus rapid test, and reactive cases were confirmed withELISA. Participants were interviewed using a questionnaire adapted for the Chilean population. Descriptive and logistic regression analyses were then performed. All applicable ethical norms were followed in the execution of this study. The total sample consisted of 375 individuals. HIV prevalence among MSM was 17.6% overall. Among the HIV-negative men, most (71.5%) had not been tested for sexually-transmitted diseases (STIs) other than HIV in the past 12 months, and 24.1% had never been tested for HIV. Participants who had been tested for an STI other than HIV in the past 12 months had a 3.56-fold greater OR for HIV-positive status than those who had not. Conversely, having had an HIV test in the past 12 months was a protective factor against positive HIV status (OR = 0.09). The high prevalence of HIV among MSM suggests a re-emergence of the disease in Chile, and cases are specifically concentrated among young MSM. Access to sexual health care and STI testing in Chile is insufficient. Targeted prevention efforts are urgently needed as part of the Chilean national strategy to combat the spread of HIV, including community-based testing programs.
