BACKGROUND Uganda's generalized HIV epidemic is well described, including an estimated adult male HIV prevalence in Kampala of 4.5%, but no data are available on the prevalence of and risk factors for HIV infection among men who have sex with men (MSM). METHODOLOGY/PRINCIPAL FINDINGS From May 2008 to February 2009, we used respondent-driven sampling to(More)
OBJECTIVE Evaluate factors associated with HIV transmission risk behavior among HIV-infected adults in Uganda. DESIGN Cross-sectional and nationally representative study (2004-2005 Uganda HIV/AIDS Sero-Behavioral Survey) tested 18,525 adults (15-59 years old) for HIV and herpes simplex virus type 2 (HSV-2). METHODS Data were weighted to obtain(More)
OBJECTIVE To determine whether observed changes in HIV prevalence in countries with generalised HIV epidemics are associated with changes in sexual risk behaviour. METHODS A mathematical model was developed to explore the relation between prevalence recorded at antenatal clinics (ANCs) and the pattern of incidence of infection throughout the population.(More)
We utilized data from the 2012 Crane Survey in Kampala, Uganda to estimate prevalence of rape among female sex workers (FSWs) and to identify risk factors for and prevalence of client-initiated gender-based violence (GBV) among FSWs. Participants were recruited using respondent-driven sampling. Analyses were weighted using RDSAT-generated individualized(More)
CONTEXT Studies of factors associated with acquiring human immunodeficiency virus (HIV) are often based on prevalence data that might not reflect recent infections. OBJECTIVE To determine demographic, biological, and behavioral factors for recent HIV infection in Uganda. DESIGN AND SETTING Nationally representative household survey of cross-sectional(More)
PURPOSE OF REVIEW Estimation of key population sizes is essential for advocacy, program planning, and monitoring of HIV epidemics in these populations. A review of recent publications on population size estimation among key populations including MSM, people who inject drugs, and male and female sex workers was conducted to identify and assess current(More)
OBJECTIVES To estimate the average social network size in the general population and the size of HIV key affected populations (KAPs) in Chongqing municipality using the network scale-up method (NSUM). METHODS A general population survey was conducted in 2011 through a multistage random sampling method. Participants aged between 18 and 60 years were(More)
BACKGROUND Uganda has one of the highest total fertility rates (TFR) worldwide. We compared the effects of antiretroviral (ARV) prophylaxis for the prevention of mother-to-child HIV transmission (PMTCT) to that of existing family planning (FP) use and estimated the burden of pediatric HIV disease due to unwanted fertility. METHODOLOGY/PRINCIPAL FINDINGS(More)
OBJECTIVES Respondent-driven sampling (RDS) is a new data collection methodology used to estimate characteristics of hard-to-reach groups, such as the HIV prevalence in drug users. Many national public health systems and international organizations rely on RDS data. However, RDS reporting quality and available reporting guidelines are inadequate. We carried(More)
Equatorial Africa has among the highest incidences of Kaposi's sarcoma (KS) in the world, thus earning the name "KS Belt." This was the case even before the HIV epidemic. To date, there is no clear evidence that HHV-8 seroprevalence is higher in this region but interpretation of the available literature is tempered by differences in serologic assays used(More)
