Bone mineral‐osteon analysis of Yupik‐inupiaq skeletons
Abstract 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. F...

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).
