Medical records were abstracted to confirm the diagnosis and clinical characteristics. Adults who were alive at the end of the study period and had a confirmed clinician diagnosis of SpA were included in prevalence calculations. We determined whether included adults had medical record documentation of meeting SpA classification criteria.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>The age-adjusted prevalence of any form of SpA was 355 per 100,000 adults (95% CI 317-397); for psoriatic arthritis it was 162 (95% CI 137-191), and for ankylosing spondylitis it was 107 (95% CI 86-131). Two-thirds (67%) of adults with any form of SpA who were tested were HLA-B27 positive. Two-thirds of adults with SpA other than psoriatic arthritis (69.1%) had documentation in their medical record to confirm that they met clinical classification criteria for axial SpA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>The prevalence of SpA in AN\/AI peoples of Alaska is lower than previously reported in this population but is higher than in most populations previously studied.
