Study design: A household sampl e of low- income urban African American adolescents 14 to19 years of age, up to two of their close friends, and their sex partners were interviewed and tested for gonorrhea and chlamydial infection. Results: Thirty- four of 145 adolescent s had at least one recent sex partner infected with Neisseria gonorrhoeae and/or Chlamydia trachomatis. The adjusted model showed that adolescents, whose recent sex partners reported having another sex partner, were more likely to have a re cent sex partner with gonorrhea and/or chlamydial infection. Conclusion: In addi tion to individual factors, network factors may explain why African American ado lescents are at increased risk for exposure to sexually transmitted infections ( STIs). Multi- level community- based interventions may need to address network factors along with personal behaviors in order to prevent STIs among low- inco me urban African American adolescents.展开更多
