Diachronic patterns of change in structural properties of the femur in the prehistoric American Southwest

<jats:title>Abstract</jats:title><jats:p>Diachronic patterns of change in the femoral diaphysis are examined in archaeological skeletal samples from the American Southwest. Three cultural periods differing in subsistence‐settlement strategies are represented: Early Villages (A.D. 500–1150), Abandonments (A.D. 1150–1300), and Aggregated Villages (A.D. 1300–1540). Relevant properties of cross‐sectional geometry and bone density were obtained using computerized tomography. Temporal trends in geometry suggest that activity levels increased between Early Villages and Abandonments, then declined during Aggregated Villages. In both sexes, femoral shape became more circular, and bending stresses were reduced in the a‐p plane through time. Compared to the other periods, bone density was the lowest during Abandonments in both sexes. The reduction in bone density may reflect declining nutritional quality through time that was especially poor during the Abandonments period. Patternings in sexual dimorphism suggest that Abandonments males may have been more sensitive to nutritional stress than contemporary females.</jats:p>
