LONG-TERM TRENDS IN SELF-REPORTED HIV RISK BEHAVIOR - INJECTION-DRUG USERS IN LOS-ANGELES, 1987 THROUGH 1995

This article reviews trends in self-reported HIV risk behaviors across serial samples of injection drug-using (IDU) arrestees interviewed in Los Angeles. Between 1987 and 1995, a gradual decrease occurred in th e percentage who share needles. However, measured over a past-year rec all period, the prevalence of needle sharing remained high until 1994 to 1995, when it abruptly declined. Needle sharing with strangers and needle sharing at shooting galleries declined gradually throughout the study period. Among IDUs who shared needles, bleach use increased rap idly until 1991 but leveled off thereafter. No change occurred in numb er of sex partners, but condom use gradually increased among IDUs with 2 or more partners. Concurrent change in local needle exchange policy and practice may explain the abrupt decline in past-year needle shari ng. New strategies may be needed to promote further increases in bleac h use and condom use.
