ASTRA (Antiretrovirals, Sexual Transmission Risk and Attitudes) is an observational questionnaire study among UK HIV outpatients. The study aims to assess current levels of sexual risk behaviours, beliefs about HIV transmission risk, and attitudes to use of early antiretroviral treatment, among HIV-diagnosed individuals attending for care, and to investigate trends over time in these factors. In particular, ASTRA will investigate whether antiretroviral treatment and viral suppression are associated with sexual risk behaviour. Two cross-sectional self-administered questionnaires will be conducted among HIV outpatients in five UK centres, in 2010/11 and 2013/14, and linked to virological and clinical data. Each questionnaire study aims to include a representative sample of outpatients attending for care at each centre, irrespective of antiretroviral treatment status.
