Objectives: To determine the prevalence of HIV infection, risk factors, and exposure to national prevention programs, identify factors associated with infection among South African youth, aged 15–24 years. Design: A cross-sectional, nationally representative, household survey. Methods: From March August 2003 we conducted a survey sexual behavior 11 904 year olds. Multivariable models for were restricted sexually experienced youth. Results: Young women significantly more likely be infected in...
Qualitative interviews are increasingly being utilized within the context of intervention trials. While there is emerging assistance for conducting and reporting qualitative analysis, limited practical resources available researchers engaging in a group coding process interested ensuring adequate Intercoder Reliability (ICR); amount agreement between two or more coders codes applied to text. Assessing reliability helps establish credibility findings. We discuss our experience calculating ICR...
BackgroundCash transfers have been proposed as an intervention to reduce HIV-infection risk for young women in sub-Saharan Africa. However, scarce evidence is available about their effect on reducing HIV acquisition. We aimed assess the of a conditional cash transfer incidence among rural South Africa.MethodsWe did phase 3, randomised controlled trial (HPTN 068) Bushbuckridge subdistrict Mpumalanga province, included girls aged 13–20 years if they were enrolled school grades 8–11, not...
To determine the seroprevalence of HIV and herpes simplex virus-2 (HSV-2) by age gender among young people aged 14--24 years in a South African town to identify risk factors for infection.A community-based, cross-sectional study was conducted on random sample men (n = 723) women 784) living township Carletonville district Africa.Potential demographic behavioural associated with were recorded questionnaire biological tests performed serum urine. Data analysis using multivariate logistic...
Background: A significant proportion of those initiating antiretroviral treatment (ART) for HIV infection are lost to follow-up. Causes discontinuing ART follow-up in resource-limited settings not well understood. Methods: retrospective analysis was conducted all adult patients receiving at an urban public clinic Johannesburg, South Africa between April 2004 and June 2005. Patients least 6 weeks were identified further studied, causes default tabulated. Results: Of 1631 267 (16.4%)...
To identify risk factors for HIV infection among young women aged 15-24 years reporting one lifetime partner in South Africa. Design In 2003, we conducted a nationally representative household survey of sexual behaviour and testing 11 904 people This analysis focuses on the subset sexually experienced with only reported sex (n = 1708).
Introduction Young adolescent women in sub‐Saharan Africa are three to four times more likely be HIV‐positive than boys or men. One of the relationship dynamics that is associated with young women's increased vulnerability HIV transactional sex. There a range HIV‐related risk behaviours may drive this vulnerability. However, date, limited epidemiological data exist on role sex increasing acquisition, especially among Africa. Our paper presents prevalence self‐reported engagement and explores...
In sub-Saharan Africa, young women who engage in transactional sex (the exchange of for money or gifts) with a male partner show an elevated risk prevalent HIV infection. We analyse longitudinal data to estimate the association between and incidence.We used from cohort 2362 HIV-negative (aged 13-20 years) enrolled randomized controlled trial rural, South Africa were followed up four visits over 6 years.The effect on incident was analysed using stratified Cox proportional hazards models...
Objectives: To use logistic regression modeling to identify factors associated with high self-efficacy for sexual negotiation and condom in a sample of South African youth. Methods: The Reproductive Health HIV Research Unit (RHRU) National Youth Survey examined nationally representative 7409 sexually active youth aged 15 24 years. We used this the main outcome self-efficacy. Results: Among female respondents (n = 3890), adjusted model were knowing how avoid (odds ratio [OR] 2.30, 95%...
Abstract HIV infection is high among South African youth but most report being unaware of their status. We explored the correlates testing using data from aged 15–24 years old who reported sexually experienced during a national survey conducted in Africa 2003 (N=7665). Among youth, 32.7% females and 17.7% males having been tested for HIV. In multivariable analysis, ever pregnant (OR = 2.97; 95% CI 2.36–3.73), starting conversation about HIV/AIDS 1.29; 1.0–1.65) urban residence 2.0;...
Adolescent reproductive health has not continued to receive the attention it deserves since start of HIV epidemic. In South Africa, high numbers adolescent women report pregnancies that are unwanted and yet few have accessed available termination pregnancy services. Enabling contraception use is vital for meeting goals prevention. A nationally representative survey African 15–24 year olds was undertaken. Participants completed a questionnaire on sexual behaviour provided an oral fluid sample...
Reduced HIV risk behavior and increased use of care support services have been demonstrated among adults accessing voluntary counseling testing (VCT). The impact VCT on adolescents is, however, not known. Focus group discussions were held with parents in two South African townships to establish the perceptions needs for young people. Ecological theory informed analysis. Adolescents had limited experience VCT, afraid knowing their status, felt that was only symptomatic individuals. Youth they...
Young people in South Africa are at high risk of HIV infection. Because first sexual experiences may influence a young person's risk, better understanding coital debut is needed.Data from nationally representative survey that included 7,692 sexually active African youth aged 15-24 were used to assess characteristics related and respondents' partner. Poisson regression analyses conducted identify relationships among these partner age differences, early (i.e., before 15), forced sex with one's...

Introduction Prevention of mother‐to‐child transmission (PMTCT) has the potential to eliminate new HIV infections among infants. Yet in many parts sub‐Saharan Africa, PMTCT coverage remains low, leading unacceptably high rates morbidity mothers and Intimate partner violence (IPV) may be a structural driver poor uptake, but received little attention literature date. Methods We conducted qualitative research three Johannesburg antenatal clinics understand links between IPV HIV‐related health...
Evidence shows that HIV prevalence among young women in sub-Saharan Africa increases almost five-fold between ages 15 and 24, with a quarter of infected by their early-to mid-20s. Transactional sex or material exchange for is relationship dynamic has been shown to have an association infection. Using five focus group discussions 19 in-depth interviews enrolled the HPTN 068 conditional cash transfer trial (2011–2015), this qualitative study explores women's perceptions transactional within...
