HIV risk behaviour in Irish intravenous drug users

The aim of the study was to measure HN prevalence and risk behaviour in 185 Irish Intravenous Drug Misusers, Information was obtained by application of a standardised WHO questionnaire covering HIV risk behaviour in the preceding 6 months, HIV serostatus was obtained by saliva/blood sample testing. One hundred and 3 (55.7 per cent) shared and 114 (61.6 per cent) lent used injecting equipment in the previous 6 months, 97 (94.2 per cent) of those who shared always cleaned the needles before use but only 48 (49.5 per cent) of these always cleaned in an efficient manner. One hundred and 14 (79.2 per cent) males and 28 (68.3 per cent) females reported heterosexual activity in the preceding 6 months, On examination sexual risk behaviour was found to be high, 50.5 per cent of males and 63 per cent of females never used condoms with regular partners, 32.6 per cent of males never used condoms with casual partners, The large majority of partners of male I.D.U'.s (both regular and casual) were non injectors, Therefore there is potential for sexual spread of HIV into the non-injecting heterosexual population, Conversely the vast majority of partners of female IDU's were injectors, This suggests that female IDU's are at higher risk of HIV infection than their male counterparts, HIV prevalence in the study group was 8.4 per cent, Implications of results for future intervention are discussed.
