To test the hypothesis that thoracic kyphosis is associated with substantial pain, disability, and height loss, we measured thoracic curvature, using an architect's flexicurve, of 610 women aged 65-91 years who were recruited from population-based listings. We assessed study subjects for back pain, back-related disability, height loss since age 25 years, perceived state of health, and bone mineral density (BMD) at the spine, calcaneus, proximal radius, and distal radius. Compared with the rest of the cohort, the 10% of women with the most severe kyphosis had 7%-17% lower BMD (p < 0.001) and had lost an additional 2.4 cm height (p < 0.001). However, kyphotic women had no greater back pain, disability caused by back problems, or poorer health. This cross-sectional study suggests that kyphosis is associated with decreased BMD and loss of height but does not cause substantial chronic back pain, disability, or poor health in older women.
为了验证胸椎后凸与严重疼痛、残疾和身高降低相关的假设，我们使用建筑用柔性曲线测量了从人群列表中招募的610名65至91岁女性的胸椎曲度。我们评估了研究对象的背痛、背部相关残疾、自25岁以来的身高降低、自我感知的健康状况以及脊柱、跟骨、桡骨近端和桡骨远端的骨密度（BMD）。与队列中的其他女性相比，胸椎后凸最严重的10%的女性骨密度低7%-17%（p<0.001），并且身高又额外降低了2.4厘米（p<0.001）。然而，后凸的女性并没有更严重的背痛、由背部问题导致的残疾或更差的健康状况。这项横断面研究表明，后凸与骨密度降低和身高降低相关，但不会在老年女性中导致严重的慢性背痛、残疾或健康不佳。
