Objectives: With some reports of HIV infection among injection drug users (IDUs) showing higher rates soon after initiation of drug use, the objective of this analysis was to determine whether recent drug risk behaviors were more common among IDUs in the first two years compared to more than two years after initiation.

Methods: IDUs were street recruited between 1997 and 1999 as a part of a multisite prospective cohort study in five US urban areas. Recent drug use behaviors (injecting with others the last time injected and injecting on average more than in the last 6 months) were examined across three sequential cohorts defined by years of injecting drug use: 0-1 years, 2-3 years, and 4-6 years.

Results: Of the 1836 subjects included in the sample, the 0-1 year IDUs group (n=619) was more likely than the 4-6 year group (n=520) to report injecting with others, the last time injected (OR=1.52, 95% CI=1.20-1.94) and to inject on average more than they did in the last six months (OR=1.44, 95% CI=1.12-1.86). The associations remained after multivariate adjustment for demographic variables (age, sex, race/ethnicity, site of recruitment, marital status, and homelessness).

Conclusions: Shorter-term new initiates are more likely to inject with others, suggesting a greater reliance on others, which may increase their risk of infection. These data suggest that prevention programs should target newly initiated IDUs and those at high risk for becoming an injector.
