 AB    OBJECTIVES: To evaluate HIV seroconversion rates and risk factors in an
       open dynamic cohort of injecting drug users (IDUs) in Montreal. METHODS:
       Consenting IDUs (all recent injectors) were recruited from the street
       and treatment centers in a follow-up cohort. Information and HIV
       serology were obtained at each visit. Univariate actuarial analysis of
       seroconversion was performed using Kaplan-Meier life time estimators.
       RESULTS: From 1988/9 to 1993/2, 55 of 608 negative subjects
       seroconverted. Total follow-up was 874 person-years for an incidence
       rate per 100 person-years of 6.3% (95% IC: 4.7-8.2). For 3 consecutive
       18 months periods, incidence rose from 4.8% (88/9-90/2), 7.5%
       (90/3-91/8) to 9.8% (after 91/9) (p = 0.046, Log-rank test). Entry
       factors associated with conversion were: street recruitment, previous
       imprisonment, cocaine preference, more than 15 injections (last 28
       days), attending a needle exchange program at least once, 2 or more
       sharing partners, sharing with an HIV+/AIDS partner, and having
       HIV+/AIDS acquaintances (all p < 0.05, Log-rank test). Factors not
       associated were: sex, booting fresh blood, injecting in shooting
       galleries, sexual orientation, prostitution and number of sexual
       partners. CONCLUSION: HIV infection seems to progress among IDUs
       recruited. Seroconversion is associated with needle sharing behaviours
       in spite of risk knowledge and relative availability of sterile
       equipment. More research is needed on impulsive determinants of sharing
       behaviours.
