HIV risk behaviors among older American drug users.

Despite increasing numbers of Americans older than 50 years of age, little is known about the impact of HIV/AIDS on aging drug users. The current study assesses the drug-related and sex-related HIV risk behaviors of older and younger injection drug users and crack smokers. Structured interview responses from 1508 out-of-treatment active drug users older than 50 years of age were compared with those of 1515 out-of-treatment active drug users who were 50 years old or younger. Comparisons were also made within the older cohort to examine differences in risk behaviors between crack smokers and nonsmokers, men and women, and users older than 60 years of age and those in their 50s. Results indicated that although older drug users (older than 50 years of age) were less likely to have had sex in the prior month, those who did were as risky as their younger counterparts with regard to sex-related risk behaviors. They were, however, significantly less risky in their needle sharing practices than those 50 years old or younger. Among the older cohort, those who smoked crack were extremely risky. Men older than 50 years of age were riskier than women older than 50 years of age; however, users older than 60 years of age were no less risky than those in their 50s. Interventions designed for older drug users should focus on sex risk behaviors, especially among those who smoke crack.
