title: Impact of social network characteristics on high-risk sexual behaviors among non-injection drug users.
abstract: Sexually active non-injection drug users in New York City and their sexual partners or fellow drug users (N = 264) were recruited from 2002 to 2005, and associations between social network characteristics and sexual risk behaviors were examined. We assessed social networks, sexual practices, and drug use. Results suggest having a drug-centered social network, i.e., a network that includes a high proportion of individuals who provide, receive, or use drugs, increases the risk of engaging in high-risk sexual behaviors. The study's limitations are noted and longitudinal studies are needed to ascertain whether these associations are causal. Funding was provided by the National Institute on Drug Abuse.
