OBJECTIVES To estimate HIV prevalence and characterize risk factors among young adults in Asembo, rural western Kenya. DESIGN Community-based cross-sectional survey. METHODS From a demographic surveillance system, we selected a random sample of residents aged 13-34 years, who were contacted at home and invited to a nearby mobile study site. Consent(More)
BACKGROUND There is need for locally-derived age-specific clinical laboratory reference ranges of healthy Africans in sub-Saharan Africa. Reference values from North American and European populations are being used for African subjects despite previous studies showing significant differences. Our aim was to establish clinical laboratory reference values for(More)
This study explored parent–child communication about HIV/AIDS among two populations disproportionately affected by HIV. Similar computer-assisted surveys were completed by parents of pre-teens, including 1,115 African American parents of 9–12-year-old children in southeastern US and 403 parents of 10–12-year-old children in Nyanza Province, Kenya.(More)
We evaluated Families Matter! Program (FMP), an intervention designed to improve parent-child communication about sexual risk reduction and parenting skills. Parents of 10- to 12-year-olds were recruited in western Kenya. We aimed to assess community acceptability and FMP's effect on parenting practices and effective parent-child communication. Data were(More)
Performances of serological parallel and serial testing algorithms were analyzed using a combination of three ELISA and three rapid tests for the confirmation of HIV infection. Each was assessed individually for their sensitivity and specificity on a blinded panel of 769 retrospective sera of known HIV status. Western blot was used as a confirmatory assay(More)
BACKGROUND In 1997, a survey in Kisumu found a prevalence of HIV infection among female sex workers (FSW) of 75%. Only 50% reported using a condom with the last client. In 2008, we conducted another survey to collect data to inform an intervention targeting FSW in Kisumu. METHODS In 2008 FSW were recruited by respondent-driven sampling. Women completed a(More)
OBJECTIVE To estimate the female sex worker population size in three cities in Côte d'Ivoire and in Kisumu, Kenya. METHODS   Capture-recapture was used, calculating size estimates by first 'tagging' a number of individuals and, through an independent recapture, calculating the proportion of overlap. The same procedures were used in all four cities. In the(More)
Evidence-based interventions (EBIs) are critical for effective HIV prevention, but time and resources required to develop and evaluate new interventions are limited. Alternatively, existing EBIs can be adapted for new settings if core elements remain intact. We describe the process of adapting the Parents Matter! Program, an EBI originally developed for(More)
OBJECTIVE To identify unique characteristics of recent versus established HIV infections and describe sexual transmission networks, we characterized circulating HIV-1 strains from two randomly selected populations of ART-naïve participants in rural western Kenya. METHODS Recent HIV infections were identified by the HIV-1 subtype B, E and D, immunoglobulin(More)
