Anonymous HIV surveillance with risk factor elicitation at Scotland's largest prison, Barlinnie
Abstract
To determine prevalence of HIV infection and risk behaviours among male inmates of Her Majesty's Prison (HMP) Barlinnie, Glasgow, Scotland on 8-9 September 1994. Cross-sectional study: voluntary, anonymous HIV surveillance (using saliva samples) of all inmates and linked self-completion risk-factor questionnaire. Of 1073 prisoners available to participate, 985 (92%) completed a risk-factor questionnaire and 982 salivettes were received for testing, of which 978 were tested for HIV antibodies (four were dry samples); 928 questionnaires passed logical checks for consistency. HIV prevalence on saliva testing, related risk behaviours and ratio of overall-to-disclosed HIV prevalence. Proportion of all inmates who have ever injected drugs, ever injected inside prison, started injecting inside, ever had acute hepatitis, had a recent personal HIV test (since January 1993). Nine saliva samples [eight injecting drug users (IDU), one recognized other risk] out of 978 were HIV-antibody-positive (three presumptively from known HIV-infected inmates). Overall HIV prevalence was estimated at 1% compared with a known prevalence of 0.4%, giving an overall-to-disclosed HIV prevalence ratio of 2.6 in HMP Barlinnie in September 1994.
