OBJECTIVES: The HIV epidemic is worsening among men who have sex with men (MSM) in China, especially among those who are younger than 25 years old [younger MSM (YMSM)]. The aim of the study was to compare the prevalences of HIV incidence and recent HIV infection as well as factors associated with recent HIV infection in YMSM and older MSM (OMSM). METHODS: A multicentre cross-sectional survey was conducted among 4496 MSM recruited from seven Chinese cities. YMSM were defined as those aged < 25 years...

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

From 2010 to 2015, young (13-24 years) Hispanic/Latino gay, bisexual and other men who have sex with men (MSM) experienced the largest increase (18%) in numbers of HIV diagnoses among all racial/ethnic groups. In 2016, the Centers for Disease Control and Prevention (CDC) assembled a team of scientists and public health analysts to develop a programmatic approach for addressing the increasing HIV diagnosis among Hispanic/Latino MSM. The team used a data driven review process, i.e., comprehensive review of surveillance, epidemiologic, and programmatic data, to explore key questions from the literature on factors associated with HIV diagnoses among Hispanic/Latino MSM and to inform the approach...

BACKGROUND: Understanding where and how young black men who have sex with men (YBMSM) in the southern United States meet their sexual partners is germane to understanding the underlying factors contributing to the ongoing HIV transmission in this community. Men who have sex with men (MSM) commonly use geosocial networking apps to meet sexual partners. However, there is a lack of literature exploring geosocial networking app use in this particular population. OBJECTIVE: Our aim was to examine the characteristics, preferences, and behaviors of a geographically diverse sample of geosocial networking app-using YBMSM in the southern United States...

PURPOSE: Criminal justice involvement is a significant problem in the United States, and poses substantial negative immediate and long-term effects, particularly among adolescents and young adults. Research has been mixed on the association between a history of arrest or incarceration and an increased risk of human immunodeficiency virus, but there are clear trends in the association between criminal justice involvement and sexual risk behaviors. METHODS: Drawing from a racially or ethnically diverse sample of young men who have sex with men, we conducted an investigation into whether there was a temporal relationship between history of criminal justice involvement and engagement in high-risk sexual behaviors...

Promoting HIV testing is an important strategy to end the HIV epidemic. HIV incidence among men who have sex with men (MSM) has increased rapidly in China in recent years, but HIV testing rates are still low. Our cross-sectional study investigated HIV testing rates and analyzed associated factors in 565 MSM in Changsha between April and December 2014. In the previous year, 37.7% of participants had not been tested, 38.2% had had one test, and 24.1% had had two or more tests. Those who initiated sexual debut at an older age, had known someone infected with HIV, or had been diagnosed with a sexually transmitted illness (STI) were more likely to have had an HIV test...

The first cases of AIDS in Spain were reported in 1982. Since then over 85,000 persons with AIDS have been cumulated, with 60,000 deaths. Current estimates for people living with HIV are of 145,000, of whom 20% are unaware of it. This explains the still high rate of late HIV presenters. Although the HIV epidemic in Spain was originally driven mostly by injection drug users, since the year 2000 men having sex with men (MSM) account for most new incident HIV cases. Currently, MSM represent over 80% of new yearly HIV diagnoses...

The number of HIV cases in Taiwan exceeded 30,000 in 2016. Per the UNAIDS 90-90-90 target, 81% of people living with HIV should receive medication. However, numerous previous studies focused on adherence rather than the initial healthcare seeking intention if diagnosed with HIV (HIV HSI). Based on the Theory of Planned Behavior (TPB), anonymous online survey data were collected from December 2016 through February 2017 from 2709 young MSM (YMSM) ages 15-39. Multivariate logistic regression found the significant factors and strengths of associations with HIV HSI varied by their HIV voluntary counseling and testing (VCT) experience...

HIV pre-exposure prophylaxis (PrEP) strategies have the potential to prevent millions of incident HIV infections each year. However, the efficacy of PrEP strategies has been plagued by issues of non-adherence, likely because of the difficulty in motivating otherwise healthy people to adhere to treatment regimens that require significant behavioral changes and daily discipline. An alternative approach to PrEP is to focus on strategies that fit in to normal, and even desirable, sexual behaviors, such as the use of cleansing enemas by men who have sex with men (MSM) prior to receptive anal intercourse (RAI)...

While research increasingly studies how neighborhood contexts influence HIV among gay, bisexual and other men who have sex with men (MSM) populations, to date, no research has used global positioning system (GPS) devices, an innovative method to study spatial mobility through neighborhood contexts, i.e., the environmental riskscape, among a sample of Black MSM. The purpose of this study was to examine the feasibility of collecting two-week GPS data (as measured by a pre- and post-surveys as well as objectively measured adherence to GPS protocol) among a geographically-diverse sample of Black MSM in the Deep South: Gulfport, MS, Jackson, MS, and New Orleans LA (n = 75)...

Human immunodeficiency virus (HIV) infection is a substantial health concern for the U.S. Department of Defense (DoD) and for service members stationed throughout the world. Each year, approximately 350 new HIV infections are diagnosed in members of the U.S. military services, with most infections acquired within the United States (1). The DoD populations most affected by HIV mirror those in the U.S. civilian population; the highest rates of new military diagnoses are in men and blacks or African Americans (blacks) (1)...

BACKGROUND: Many young men who have sex with men (YMSM) are reluctant to seek health services and trust local physicians. Online information seeking may encourage YMSM to identify and see trustworthy physicians, obtain sexual health services, and obtain testing for sexually transmitted infections (STIs). This study examined online STI information seeking behaviors among Chinese YMSM and its association with offline physician visits. METHODS: We conducted a nationwide online survey among YMSM through WeChat, the largest social media platform in China...

Intimate partner violence (IPV) and its association with HIV infection among men who have sex men (MSM) in China are not understood. In this study, 732 MSM recruited from Shanghai, China between March and August 2015 were administered with a questionnaire survey and HIV blood testing. IPV victimization was measured by 25 forced-choice items capturing lifetime experience of physical, sexual, psychological, deprivation or neglect, and other forms of violence. Of them, 179 (24.3%) reported having experienced at least one type of IPV victimization...

Understanding pre-exposure prophylaxis (PrEP) discontinuation is key to maximizing its effectiveness at the individual and population levels. Data came from the RADAR cohort study of MSM aged 16-29 years, 2015-2017. Participants included those who reported past 6-month PrEP use and discontinued its use by the interview date. Of the 197 participants who had used PrEP in the past 6 months, 65 discontinued use. Primary reasons for PrEP discontinuation included trouble getting to doctor's appointments (14, 21...

While research investigates the role and influence of geo-social networking (GSN) applications on HIV, less is known about the impact of GSN functions on disease transmission. In our formative research on young Black men who have sex with men's (YBMSM) technology use patterns and preferences for a smartphone-based HIV prevention intervention, we found that study participants used GSN "block" and "filter" functions as protective mechanisms against racism and racial sexual discrimination. Yet, we suggest that these functions may unintentionally create restrictive sexual networks that likely increase their risk for disease transmission...
