ASTRA Study

The ASTRA study aimed to assess sexual risk behaviours, beliefs about HIV transmission risk, and attitudes to use of early antiretroviral treatment, in patients with HIV under care within the UK.

A cross-sectional self-administered questionnaire study took place among UK HIV outpatients, in 2011/12. The study was conducted among those attending clinics in 8 different centres in the UK with the aim of including a representative sample of outpatients attending for care at each centre, irrespective of antiretroviral treatment status.
