A prospective, comparative study of the prevalence of enteric protozoa was determined among human immunodeficiency virus (HIV)- positive and HIV-negative men who have sex with men (MSM) in Sydney, Australia. A total of 1,868 patients submitted stool specimens; 1,246 were from MSM (628 HIV positive and 618 HIV positive) and 622 from non-MSM were examined over a 36-month period. A total of 651 (5...

BACKGROUND Men who have sex with men (MSM) are at high risk of HIV and sexually transmitted infections (STIs) in China and globally. Engaging in commercial sex put them at even greater risk. This study estimated the prevalence of HIV/STIs among three subgroups of MSM: MSM who sold sex (MSM-selling), MSM who bought sex (MSM-buying), and non-commercial MSM (NC-MSM) and evaluated the relationship ...

INTRODUCTION Transmission of Hepatitis C virus (HCV) among HIV-positive men who have sex with men (MSM) in the United Kingdom is ongoing. We explore associations between self-reported sexual behaviours and drug use with cumulative HCV prevalence, as well as new HCV diagnosis. METHODS ASTRA is a cross-sectional questionnaire study including 2,248 HIV-diagnosed MSM under care in the United King...

BACKGROUND Population-based HIV incidence, prevalence, and mortality rates among men who have sex with men (MSM) have been unavailable, limiting assessment of racial/ethnic disparities and epidemic dynamics. METHODS Using estimated numbers of MSM aged >or=18 years by race/ethnicity as denominators, from models in our prior work, we estimated MSM HIV prevalence and mortality rates for 2006-200...

BACKGROUND Estimated numbers of men who have sex with men (MSM) by race/ethnicity and mortality rates among such MSM with HIV/AIDS are unavailable. This hampers efficient targeting of HIV/AIDS prevention and care resources. METHODS An existing estimation methodology was adapted to develop MSM population estimates by race/ethnicity for Miami-Dade County, Florida. We ascertained and characteriz...

In the United States, men who have sex with men (MSM) constitute the risk group in which the prevalence of new HIV infection is increasing. The percentage of undiagnosed HIV infection and HIV risk behaviors in MSM and non-MSM participating in an emergency department-based rapid HIV screening program were compared. Medical records of all male patients participating in the program from May 2008 t...

OBJECTIVES To examine the epidemiology of HIV among black and minority ethnic (BME) men who have sex with men (MSM) in England and Wales (E&W). METHODS Ethnicity data from two national HIV/AIDS surveillance systems were reviewed (1997-2002 inclusive), providing information on new HIV diagnoses and those accessing NHS HIV treatment and care services. In addition, undiagnosed HIV prevalence amo...

BACKGROUND Recruiting valid samples of men who have sex with men (MSM) is a key component of the US human immunodeficiency virus (HIV) surveillance and of research studies seeking to improve HIV prevention for MSM. Social media, such as Facebook, may present an opportunity to reach broad samples of MSM, but the extent to which those samples are comparable with men recruited from venue-based, ti...

BACKGROUND Although increased prevalence of transfusion transmissible infections (TTI) among "men who have sex with men" (MSM) has been well documented, the exclusion of MSM as blood donors is contested. The aim of this systematic review is to find studies that describe the risk of TTI in MSM blood donors. METHODS We searched MEDLINE, Embase, The Cochrane Central Register of Controlled Trials...

Introduction The aim of this study was to assess sexual behavior and measure HIV prevalence among MSM in 2015, in Togo. Methods We conducted a cross-sectional study from February to March 2015 in nine major cities of Togo. The respondent-driven sampling method was used to recruit MSM. Behavioral data were collected by interviewer-administered questionnaires. The blood tests were then carried ...
