Comparative StudyRadiographic measurements, bone mineral density, and the Singh Index in the proximal femur of white and black postmenopausal women.
Radiographic measurements, bone mineral density (BMD), and the Singh Index were examined to assess ethnic differences in the architecture and trabecular patterns in the proximal femur. ⋯ There was no significant ethnic difference in mean age, height, or body mass index, but weight and BMD was higher in the black group at all regional sites. The inferior neck cortical thickness was significantly greater in the black group. The Singh Index was found to be grade VI (normal) in 87%, grade V in 9%, and grades II-IV in 4% of all subjects. Multiple regression models explained 35% to 60% of the variance in the regional BMDs; the Singh Index, weight, and subtrochanteric cortical thicknesses were significant contributors to all regional hip BMD models. Although there were ethnic differences in BMD, there were no ethnic differences in the distribution of the Singh Index scores.
