Abstract

Objectives. We described prevalence estimates of high-risk human papillomavirus (HR-HPV), HPV types 16 and 18, and abnormal Papanicolaou (Pap) smear tests among American Indian/Alaska Native (AI/AN) women compared with women of other races/ethnicities. Methods. A total of 9,706 women presenting for cervical screening in a sentinel network of 26 clinics (sexually transmitted disease, family planning, and primary care) received Pap smears and HR-HPV type-specific testing. We compared characteristics of 291 women self-identified as AI/AN with other racial/ethnic minority groups. Results. In our population, AI/AN and non-Hispanic white (NHW) women had similar age- and clinic-adjusted prevalences of HR-HPV (29.1%, 95% confidence interval [CI] 23.9, 34.3 for AI/AN women vs. 25.8%, 95% CI 24.4, 27.2 for NHW women), HPV 16 and 18 (6.7%, 95% CI 3.9, 9.6 for AI/AN women vs. 8.8%, 95% CI 7.9, 9.7 for NHW women), and abnormal Pap smear test results (16%, 95% CI 11.7, 20.3 for AI/AN women vs. 14.9%, 95% CI 13.7, 16.0 for NHW women). AI/AN women had a higher prevalence of HR-HPV than Hispanic women, and a similar prevalence of HPV 16 and 18 as compared with Hispanic and African American women. Conclusions. We could not demonstrate differences in the prevalence of HR-HPV, HPV 16 and 18, or abnormal Pap smear test results between AI/AN and NHW women. This finding should improve confidence in the benefit of HPV vaccine and Pap smear screening in the AI/AN population as an effective strategy to reduce rates of cervical cancer.
