Risk reduction among injecting drug users: Changes in the sharing of injecting equipment and in condom use

In an investigation of risk behaviour among injecting drug users in the North-West of England, information was obtained concerning the sharing of injecting equipment, respondent's sexual partners and the use of condoms. Between six and nine months after the initial contact, 169 respondents (56%) were contacted again. The emphasis in the second phase of the project was on changes, if any, in risk behaviour that had occurred in the intervening period. Significant reductions were found in sharing, mostly in the more indiscriminate use of others' injecting equipment. No reduction was observed in sharing between injecting partners and little in sharing between close friends. The number of sexual partners had decreased and the use of condoms, although it increased among those involved in temporary relationships, remained low. Impediments to further progress in risk reduction are discussed.
