This paper examines the sexual risk behavior of female injecting drug
users who participated in a 4 year longitudinal study. Both HIV+ and H
IV- women showed increases in monogamy, decreases in the frequency of
unprotected vaginal/anal sex, and decreases in a risk index score thro
ughout the study. HIV+ women had fewer occasions of unprotected sex th
an HIV-. However, a substantial proportion of the sample continued to
engage in unprotected sex. Among the HIV+ women, depressed mood was si
gnificantly related to abstinence and to fewer occasions of unprotecte
d sex, but CD4, medical symptoms, neurological impairment, and memory
test performance were not associated with sexual risk behavior.
