与美国白人相比，来自圣劳伦斯岛、北阿拉斯加和加拿大的活着的成年爱斯基摩人经历了与年龄相关的骨矿物质丢失更早、更快的速度。对来自圣劳伦斯岛(n=53)、科迪亚克岛(n=92)、巴芬岛(n=44)和南安普顿岛(n=69)的爱斯基摩人成年骨骼的女性骨芯进行了分析，并与来自美国白人(n=144)的骨芯结果进行了比较。测量每个髓核的皮质厚度、髓核的骨矿含量、皮质骨密度、次级骨量和哈弗氏管的数目和面积。通过组织学方法估计死亡年龄，并与爱斯基摩人骨骼的形态方法估计的死亡年龄进行比较。已知的死亡年龄与美国白人系列的组织学估计死亡年龄进行了比较。劳伦斯岛和科迪亚克岛(说尤皮克语)爱斯基摩人的皮质厚度值显著(P<；0.05)大于巴芬岛和南安普顿岛(说Inupiaq人)的爱斯基摩人的皮质厚度值，但小于美国白人的皮质厚度值。南安普顿爱斯基摩股骨的骨矿含量是本研究中发现的最低。对股骨切片的组织学分析表明，爱斯基摩人的单位面积上含有比美国白人更多的骨质。在两组人群中，骨小梁的大小没有发现差异。爱斯基摩人和白人之间的骨质重塑模式的差异被推断出来。使用美国白色回归方程的组织学方法在爱斯基摩人中估计死亡年龄，得到的年龄估计与通过形态学方法得到的结果不太一致。
Living adult Eskimos from St. Lawrence Island, North Alaska, and Canada undergo an earlier and more rapid rate of age‐related bone mineral loss compared with U.S. whites. Further, it has been shown that Eskimos and Indians differ in patterns of osteon remodeling at the Haversian envelope.Femoral bone cores from adult Eskimo skeletons from St. Lawrence Island (n = 53), Kodiak Island (n = 92), Baffin Island (n = 44), and Southampton Island (n = 69) were analyzed and the results compared with those obtained from cores from U.S. whites (n = 144). Cortical thickness, bone mineral content of cores, cortical bone density, secondary osteon and Haversian canal number and area were quantified for each core. Ages at death were estimated by histological methods and compared with the ages at death estimated by morphological methods for the Eskimo skeletons. Known ages at death were compared with histologically estimated ages at death for the U.S. white series.St. Lawrence Island and Kodiak Island (Yupik speakers) Eskimo cortical thickness values were significantly (P < .05) greater than Baffin Island and Southampton Island (Inupiaq speakers) Eskimo cortical thickness values but less than the cortical thickness values for U.S. whites. The bone mineral content of the Southampton Eskimo femoral cores was the lowest found in this study. Histological analysis of the femoral bone sections showed that Eskimos contain more osteons per unit area than U.S. whites. No differences in osteon size were noted between the two populations. Differences in patterns of osteon remodeling between Eskimos and whites were inferred.Age at death estimations by histological methods in Eskimos using U.S. white regression equations yielded age estimates in poor agreement with those obtained by morphological methods.
