Background: National STD rates among American Indians and Alaska Natives (AI/AN) are up to 4.5 times higher than rates for whites, with differences even more pronounced at some regional levels.
Objectives: Describe STD rates and trends among AI/AN by region.
Methods: During 1998-2007, we calculated crude annualized rates for chlamydia (CT), gonorrhea (GC), and primary and secondary syphilis (P&S) for AI/AN living in counties on or near reservations in the 12 Indian Health Service (IHS) Areas. Numerators were based on county-level STD cases reported to CDC, and denominators were based on census population estimates. We compared rates with those in the general
Results: In 2007, the overall AI/AN CT rate (732.9) was two times higher than the
Conclusions: AI/AN STD rates vary considerably by region. Further studies are necessary to identify determinants for these differences.
Implications for Programs, Policy, and/or Research: Regional data should be used to guide local STD prevention and control efforts in Indian Country.
