Substance Use <strong>and</strong><br />

<strong>HIV</strong>-Transmitting Behaviors<br />

<strong>Among</strong> Gay <strong>and</strong> Bisexual Men<br />

David G. Ostrow<br />

INTRODUCTION<br />

This chapter reviews what is known about the relationships between<br />

nonmedical psychoactive drug (NMPD) use <strong>and</strong> human<br />

immunodeficiency virus type 1 (<strong>HIV</strong>-1) 1 infection, <strong>HIV</strong>-related disease,<br />

<strong>and</strong> acquired immunodeficiency syndrome (AIDS) in men who have sex<br />

with men. <strong>The</strong> review is limited to the published literature, which is,<br />

however, quite large in several areas <strong>of</strong> specific relevance to <strong>HIV</strong><br />

infection <strong>and</strong> AIDS.<br />

By far the largest area <strong>of</strong> interest concerns intravenous (IV) drug use<br />

because <strong>of</strong> the obvious relationship to a major <strong>and</strong> growing route <strong>of</strong><br />

transmission <strong>of</strong> <strong>HIV</strong>. While this chapter does not specifically address the<br />

issues <strong>of</strong> IV drug use <strong>and</strong> <strong>HIV</strong> infection, several recently published<br />

reviews (Des Jarlais et al. 1991; Schoenbaum et al. 1989; <strong>and</strong> Ross et al.<br />

1992) provide comprehensive <strong>and</strong> up-to-date information regarding the<br />

behavioral <strong>and</strong> mental health aspects <strong>of</strong> this important subject. Rather,<br />

this chapter focuses on nonparenterally used NMPDs <strong>and</strong> their<br />

relationship to <strong>HIV</strong> transmission behaviors, specifically high-risk sexual<br />

behavior. It also discusses the secondary community impact <strong>of</strong> these<br />

associations <strong>and</strong> their intervention implications. Readers interested in a<br />

more detailed discussion <strong>of</strong> published studies concerning the potential<br />

effects <strong>of</strong> NMPD use on the natural history <strong>of</strong> <strong>HIV</strong> infection are referred<br />

to the recently published monograph, C<strong>of</strong>actors in <strong>HIV</strong>-1 Infection <strong>and</strong><br />

AIDS (Watson 1990).<br />

Many <strong>of</strong> the published reports <strong>and</strong> all <strong>of</strong> the tables <strong>and</strong> figures in this<br />

chapter come from the Chicago Multicenter AIDS Cohort Study (MACS)<br />

cohort, one <strong>of</strong> the four National Institute <strong>of</strong> Allergy <strong>and</strong> Infectious<br />

Diseases (NIAID)-funded collaborative natural history <strong>of</strong> <strong>HIV</strong> study sites,<br />

<strong>and</strong> its companion National Institute <strong>of</strong> Mental Health (NIMH)-funded<br />

behavioral/mental health add-on study, the Coping & Change Study<br />

(CCS). 2 Over 1,000 gay <strong>and</strong> bisexual men volunteered for these studies<br />
