Do behavioural differences help to explain variations in HIV prevalence in adolescents in sub-Saharan Africa?
Ruth Chapman,Richard G. White,Leigh Anne Shafer,Audrey Pettifor,Owen Mugurungi,David Ross,Sophie Pascoe,Frances M. Cowan,Heiner Grosskurth,Anne Buvé,Richard J. Hayes +10 more
TL;DR: To compare adolescent risk factors for HIV infection in two countries with high adolescent HIV prevalence and two lower prevalence countries with the aim of identifying risk factors that may help explain differences in adolescent HIVPrevalence.

The dual impact of antiretroviral therapy and sexual behaviour changes on HIV epidemiologic trends in Uganda: a modelling study.
Leigh Anne Shafer,Rebecca N. Nsubuga,Ruth Chapman,Katie O'Brien,Billy N. Mayanja,Richard G. White +5 more
TL;DR: Modelling suggests that ART will reduce HIV incidence over 20 years, and increase prevalence, and policy makers are urged to continue HIV prevention activities, including promoting sex education, and to be prepared for a higher than previously suggested number of HIV infected people in need of treatment.

Polygyny and symmetric concurrency: comparing long-duration sexually transmitted infection prevalence using simulated sexual networks.
Shalini Santhakumaran,Katie O'Brien,Roel Bakker,Toby Ealden,Leigh Anne Shafer,Rhian Daniel,Ruth Chapman,Richard J. Hayes,Richard G. White +8 more
TL;DR: In this paper, the authors compared the effects of polygyny and gender-symmetric concurrency on prevalence of long-duration sexually transmitted infections (STIs) using a dynamic stochastic network model.
The role of the natural epidemic dynamics and migration in explaining the course of the HIV epidemic in rural Uganda: a modelling study
Leigh Anne Shafer,Richard G. White,Rebecca N Nsubuga,Ruth Chapman,Richard J. Hayes,Heiner Grosskurth +5 more
TL;DR: Some of the increasing HIV prevalence in Uganda since 2000 may be due to increased risky behaviour, but some of the observed epidemiologic trends would likely occur without any intentional change in behaviour.
Antiretroviral therapy and sexual behavior in Uganda: a cohort study.
Leigh Anne Shafer,Rebecca N. Nsubuga,Richard G. White,Billy N. Mayanja,Ruth Chapman,Katie O'Brien,Lieve Van der Paal,Heiner Grosskurth,Dermot Maher +8 more
TL;DR: Evidence for sexual behavior change in response to antiretroviral therapy (ART) among members of a Ugandan clinical cohort is assessed and some evidence suggests that the availability of ART may impact risky behavior among HIV-uninfected people, although this was inconsistent across different reported behavior variables.
