Objectives We examined the potential influence of both sample selection effects and Hawthorne effects in the behavioural HIV Prevention Trial Network 068 study, designed to examine whether cash transfers conditional on school attendance reduce HIV acquisition in young South African women. We explored whether school enrolment among study participants differed from the underlying population, and whether differences existed at baseline (sample selection effect) or arose during study participation (Hawthorne effect). Methods We constructed a cohort of 3889 young women aged 11-20 years using data from the Agincourt Health and socio-Demographic Surveillance System. We compared school enrolment in 2011 (trial start) …

Introduction: Prevalence of HIV among young women in South Africa remains extremely high. Adolescent peer groups have been found to be an important influence on a range of health behaviours. The characteristics of young women's friendships might influence their sexual health and HIV risk via connections to sexual partners, norms around sexual initiation and condom use, or provision of social support. We investigated associations between young women's friendships and their Herpes Simplex Virus Type 2 (HSV-2) and HIV infection status in rural South Africa. Methods: Our study is a cross-sectional, egocentric network analysis. In 2011 to 2012, we tested 13- …

Background Despite the benefits of physical activity during pregnancy, the physiological and psychological changes that occur during this unique period may put women at greater risk of being sedentary. Lifestyle and environmental transitions have left black South African women at increased risk of physical inactivity and associated health risks. Therefore, the aim of this qualitative study was to describe the beliefs regarding physical activity during pregnancy in an urban African population. Methods Semi-structured interviews (n = 13) were conducted with pregnant black African women during their third trimester. Deductive thematic analysis was completed based on the Theory of Planned Behaviour. …

To develop an FFQ for estimating culture-specific maize intake that can distinguish between home-grown and commercial maize. Home-grown maize is more likely to be contaminated with fumonisins, mycotoxins that are associated with increased risk of oesophageal cancer. An existing FFQ developed for use in urban Xhosa populations was used as the initial framework for the maize-specific FFQ (M-FFQ). The existing questionnaire contained 126 food items divided into ten food groups (bread, cereals, vegetables, fruit, meat, dairy, snacks, condiments, beverages and fat). The M-FFQ was developed based on additional data obtained from a literature search, 24 h recalls (n 159), in-depth …

Objective 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 HIV testing among 11 904 young people aged 15-24 years in South Africa. This analysis focuses on the subset of sexually experienced young women with only one reported lifetime sex partner (n = 1708). Methods Using the proximate determinants framework and the published literature we identified factors associated with HIV in young women. The associations between these factors and HIV infection were explored in multivariable …

Background Adolescent reproductive health has not continued to receive the attention it deserves since the start of the HIV epidemic. In South Africa, high numbers of adolescent women report pregnancies that are unwanted and yet few have accessed available termination of pregnancy services. Enabling contraception use is vital for meeting the goals of HIV prevention. Methods A nationally representative survey of South African 15-24 year olds was undertaken. Participants completed a questionnaire on sexual behaviour and provided an oral fluid sample for HIV testing. Analysis of the data was restricted to women (n = 6217), particularly those who reported being …

Objectives: To use logistic regression modeling to identify factors associated with high self-efficacy for sexual negotiation and condom use in a sample of South African youth. Methods: The Reproductive Health and HIV Research Unit (RHRU) National Youth Survey examined a nationally representative sample of 7409 sexually active South African youth aged 15 to 24 years. We used logistic regression modeling in this sample to identify factors associated with the main outcome of high self-efficacy. Results: Among female respondents (n = 3890), factors associated with high self-efficacy in the adjusted model were knowing how to avoid HIV (odds ratio [OR] = …

The prevalence of HIV infection in Africa is substantially higher among young women than it is among young men. Biological explanations of this difference have been presented but there has been little exploration of social factors. In this paper we use data from Carletonville, South Africa to explore various social explanations for greater female infection rates. This paper reports on data from a random sample of 507 people between 13 and 24 years old. Subjects were tested for HIV, as well as other sexually transmitted infections (STIs), and answered a behavioural questionnaire. The age-prevalence of HIV infection differs between men …

Levels of heterosexually transmitted HIV infection are high amongst South African youth, with one recent survey reporting levels of 18.9% amongst 17-20 year olds and 43.1% amongst 21-25 year olds. In these groups levels of knowledge about HIV are high, but perceived vulnerability and reported condom use are low. Much existing research into youth HIV in developing countries relies on survey measures which use individual knowledge, attitudes and reported behaviour as variables in seeking to explain HIV transmission amongst this group. This paper reports on a focus group study that seeks to complement existing individual-level quantitative findings with qualitative findings …
