INTRODUCTION Literature on the age at first anal intercourse (AFAI) among men who have sex with men (MSM) is limited. We aimed to elucidate the evolution of AFAI and the factors associated with early AFAI, based on a large sample of MSM in China. METHODS We collected information on the demographics and sexual behaviours of MSM from seven large cities in China from 2012 to 2013. Blood samples ...

PURPOSE OF REVIEW Numerous studies reported the rapid spread of HIV/AIDS epidemic among men who have sex with men (MSM) in China. This paper aims to investigate the overall epidemic trend and associated high-risk behaviours among Chinese MSM and to explore the governmental and community responses to the epidemic. RECENT FINDINGS HIV prevalence among Chinese MSM increased rapidly in all Chines...

Epidemics of HIV in men who have sex with men (MSM) continue to expand in most countries. We sought to understand the epidemiological drivers of the global epidemic in MSM and why it continues unabated. We did a comprehensive review of available data for HIV prevalence, incidence, risk factors, and the molecular epidemiology of HIV in MSM from 2007 to 2011, and modelled the dynamics of HIV tran...

IntroductionOutbreaks of invasive meningococcal disease (IMD) among men who have sex with (MSM) caused by a hypervirulent, non-encapsulated Neisseria meningitidis (Nm) clone belonging to genogroup C been described. We aimed determine the oral and anal carriage rates genogroups Nm MSM living HIV.MethodsSexually active HIV were included. A questionnaire, an wash sample swab collected at baseline ...

BACKGROUND Recreational drug use is associated with high-risk sexual behavior and sexually transmitted infections (STIs). We assessed the prevalence of drug use during sex and the associations between such use and STI (chlamydia, gonorrhea, or syphilis). METHODS During 3 periods in 2008 and 2009, attendees of an STI clinic in Amsterdam were interviewed about sexual behavior and drug use durin...

OBJECTIVES To describe the extent to which Centers for Disease Control and Prevention (CDC)-funded HIV testing in nonhealthcare facilities reaches adolescent MSM, identifies new HIV infections, and links those newly diagnosed to medical care. METHODS/DESIGN We describe HIV testing, newly diagnosed positivity, and linkage to medical care for adolescent MSM who received a CDC-funded HIV test in...

BACKGROUND Little research has been conducted on the human immunodeficiency virus (HIV) epidemic and the sexual intercourse habits of men who have sex with men (MSM) in crowded places, both locally and abroad. This study conducted a survey of MSM in different locales of Inner Mongolia to provide a reference for developing strategies or measures to prevent and control HIV among this understudied...

In Ireland, men who have sex with men (MSM) have increased HIV risk. Pre-exposure prophylaxis (PrEP), combined with safe sex practices, can reduce HIV acquisition. We estimated MSM numbers likely to present for PrEP by applying French PrEP criteria to Irish MSM behavioural survey data. We adjusted for survey bias, calculated proportions accessing testing services and those likely to take PrEP. ...

BACKGROUND Measuring prevalence and incidence of sexually transmitted infections in hard to reach populations like men who have sex with men (MSM) is hampered by unknown size and regional distribution of this population. Community sample- and study-based measurements are often fraught with participation biases and do not allow generalization of the results for other regions or the whole populat...

BACKGROUND Men who have sex with men (MSM) bear a disproportionately higher burden of HIV infection than the general population. MSM in the Middle East and North Africa (MENA) are a largely hidden population because of a prevailing stigma towards this type of sexual behavior, thereby limiting the ability to assess infection transmission patterns among them. It is widely perceived that data are ...
