Long-term trends in self-reported HIV risk behavior: injection drug users in Los Angeles, 1987 through 1995

Abstract

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 the percentage who share needles. However, measured over a past-year recall 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 rapidly until 1991 but leveled off thereafter. No change occurred in number 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 sharing. New strategies may be needed to promote further increases in bleach use and condom use.

PIP: Trends are reviewed in self-reported HIV risk behaviors across serial samples of 2156 arrested IV drug users (IVDUs) interviewed in Los Angeles, California. All IVDUs reported past-year injection drug use between 1987 and 1995. Over the period 1987-95, a gradual decrease occurred in the percentage who share injection equipment. However, measured over a past-year recall period, the prevalence of needle sharing at shooting galleries remained high until 1994/95, when it abruptly declined. Needle sharing with strangers and at shooting galleries declined gradually throughout the study period. Among IVDUs who shared needles, bleach use increased rapidly until 1991, then leveled off thereafter. No change occurred in the number of sex partners, but condom use gradually increased among IVDUs with 2 or more partners. Concurrent change in local needle exchange policy and practice may explain the abrupt decline in past-year needle sharing. New strategies may be needed to promote further increases in bleach and condom use.
