Epidemiologic Differences Between Native-Born and Foreign-Born Black People Diagnosed with HIV Infection in 33 U.S. States, 2001-2007

摘要

Objective. Few studies have examined the extent to which foreign-born people contribute to the human immunodeficiency virus (HIV) epidemic among non-Hispanic black people in the U.S. We sought to determine differences in the epidemiology of HIV infection among native- and foreign-bom black people, using data from the national HIV surveillance system of the Centers for Disease Control and Prevention.Methods. We estimated the number of HIV infections among black adults and adolescents diagnosed from 2001 to 2007 in 33 U.S. states. We compared annual HIV diagnosis rates, distributions of demographic characteristics and HIV-transmission risk factors, late diagnoses of HIV infection, and survival after an acquired immunodeficiency syndrome (AIDS) diagnosis for native- and foreign-born black people.Results. From 2001 to 2007, an estimated 100,013 black adults and adolescents were diagnosed with HIV infection in 33 U.S. states, for which country-of-birth information was available. Of these, 11.7% were foreign-born, with most from the Caribbean (54.1%) and Africa (41.5%). Annual HIV diagnoses decreased by 5.5% per year (95% confidence interval [CI]-5.9, -5.0) among native-born black people. Decreases were small among foreign-born black people (-1.3%; 95% CI -2.6, -0.1), who were more likely to be female, have HIV infection attributable to high-risk heterosexual contact, be diagnosed with AIDS within 12 months of HIV diagnosis, and survive one year and three years after an AIDS diagnosis.Conclusions. The epidemiology of HIV infection differs for foreign-born black individuals compared with their native-born counterparts in the U.S. These data can be used to develop culturally appropriate and relevant HIV-prevention interventions.
