Abstract: | This study examines changes in the multi-person use of drug injection paraphernalia during the mid-1990s, a time of increasing awareness of HIV transmission modes and availability of prevention programs. Beginning in 1994, 794 street-recruited injection drug users in Chicago were interviewed and followed at 6 and 12 months postbaseline. Random-effects, pattern-mixture logistic regression models were used to determine correlates of five injection-equipment sharing practices, while accounting for repeated measurement and study attrition. At baseline, 45.7% of participants reported receptive syringe sharing in the previous 6 months. Syringe-mediated sharing was reported by 28.7% of participants and the sharing of cookers (65.1%), cotton filters (55.7%), and rinse water (46.9%) was common. During follow-up, the proportion of all sharing behaviors decreased significantly, especially receptive syringe sharing. Participation in a syringe exchange program was associated with reductions in receptive syringe sharing and syringe-mediated sharing, but not the sharing of cookers. |
