Fuller, C.M., L. Borrel, C. Latkin, Sandro Galea, D. Ompad, S.A. Strathdee, and D. Vlahov. 2005. "The Effect of Race, Neighborhood, and Social Network on Age of Initiation of Injection Drug Use." American Journal of Public Health, 95: 689-695.
Objectives. We investigated individual- and neighborhood-level factors associated with adolescent initiation of injection drug use. Methods. Injection drug users (IDUs) who had been injecting 2 to 5 years underwent HIV testing and completed a sociobehavioral risk survey. Modeling techniques accounting for intraneighborhood correlations were used in data analyses.
Results. Adolescent-initiating IDUs were less likely than adult-initiating IDUs to report high-risk sex and injection behaviors and more likely to report high-risk networks. African American IDUs from neighborhoods with large percentages of minority residents and low adult educational levels were more likely to initiate injection during adolescence than White IDUs from neighborhoods with low percentages of minority residents and high adult education levels.
Conclusions. Racial segregation and neighborhood-level educational attainment must be considered when drawing inferences about age at initiation of injection drug use and related high-risk behaviors
