For epidemiologic studies of spondyloarthropathy in circumpolar peoples of Chukotka, Russia and Alaska, we gathered demographic, physical and laboratory data to provide a background for evaluating and comparing factors that may influence susceptibility and clinical expression of disease. The study groups included the Chukchi and Siberian Eskimo of Russia and the Inupiat and Yupik Eskimo of Alaska. The 4 groups were remarkably similar in population structure, educational attainment, mean hemoglobin concentrations and frequency of the Class I histocompatibility antigen HLAB27. The Alaskan and Chukotkan groups were similar in mean height, but the Alaskans had higher body weights and significantly greater body mass indexes, probably a reflection of a shift away from traditional lifestyle and diet. Differences in the frequencies of ABO and MN blood group antigens were also apparent, with higher frequencies of blood group M in the Alaskan populations, particularly the Inupiat.
