High school students' knowledge of HIV/AIDS and perceived risk of currently having AIDS

Factors associated with AIDS knowledge and perceived risk of currently having HIV infection among adolescents were examined. A modified version of the Centers for Disease Control's Health Risk Survey was administered to 11th and 12th grade students (N = 2,483) in homerooms from nine schools in one southeastern community. Knowledge was based on cumulative responses to 12 questions. Many adolescents incorrectly answered seven questions. Based on multivariate analysis of variance, lower AIDS knowledge was associated with no prior school-based AIDS education (p less than or equal to 0.0001), previous IV drug use (p less than or equal to 0.0001), male gender (p less than or equal to 0.0001), and being Black or "other" ethnic group (p less than or equal to 0.0001). Based on interaction effects, Hispanics not receiving AIDS education in school (p less than or equal to 0.0001) and Black and "other" ethnic group IV drug users (p less than or equal to 0.0011) had a lower AIDS knowledge. When controlling for AIDS knowledge level (p less than or equal to 0.0001), higher perceived risk of current infection with HIV was associated with previous IV drug use (p less than or equal to 0.0001) and male gender (p less than or equal to 0.0001). However, previous IV drug users who never received AIDS education (p less than or equal to 0.0001) or were from Black or "other" ethnic group (p less than or equal to 0.008) had higher perceived risks of presently having HIV infection.
