Abstract
  Anal intercourse (AI) is a recognized HIV risk behavior, yet little is
  known about AI among adolescent girls and young women. The authors studied
  the prevalence and correlates of heterosexual AI (HAI) among Black and
  Latina adolescent girls and young women. The data come from two randomized
  clinical trials (RCTs) of HIV prevention interventions with Black and
  Latina adolescent girls and young women. In the second RCT, a Sexual
  Relationship Power Scale was added to the questionnaire. Thirty-five
  percent of participants in the first RCT (N =244) and 23% of those in the
  second RCT (N =101) reported engaging in HAI, most without a condom.
  Significant correlations existed between HAI and a high-risk sexual
  history. HAI is prevalent in this population. Nurses must educate female
  adolescent patients about risks associated with HAI.
