title: Risk contexts and risk behaviors in the Euregion Maas-Rhein: the Boule de Neige intervention for AIDS prevention among drug users.
abstract: Using targeted sampling, self-reported data of 1,767 drug users in the Euregion Maas-Rhein were collected over 3 years. Forty-two percent of the injection drug users shared syringes with sexual partners and 47.8% with friends. Eighty-one percent of the total sample had sexual contact in the last 6 months, half of whom with one person and half with two or more. Significant predictors of high-risk drug use were injecting in the presence of others, injection onset before the age of 20, female gender, and not living in The Netherlands. Participation in needle exchange or methadone programs and sufficient knowledge of risk factors was not significantly related to a reduction of high-risk drug use behavior. High-risk sexual behavior was found to be related to male gender, under the age of 30 and to multiple sexual partners. We conclude that in a social context where needle exchange, methadone programs, and sufficient knowledge of risk factors among the drug user population exist, AIDS prevention can be improved through behavioral skills training and developing specific interventions that target the peer group environments, rituals, partner relationships, and lifestyles of drug users.
