  1. Health-related quality of life was correlated with all sagittal parameters, particularly sagittal vertical axis, T1 pelvic angle, KneeFlex angle, and AnkleFlex angle. Age was correlated with health-related quality of life and the Oswestry Disability Index.
  2. Compared with older adults aged ≥50 years, younger adults aged ≤50 years exhibited less deviation in sagittal alignment, including thoracic kyphosis, lumbar lordosis, pelvic incidence, pelvic tilt, sagittal vertical axis, and T1 pelvic angle.
  3. Women had significantly lower muscle mass, muscle strength, and bone density than men.
  4. The three-dimensional odontoid–hip axis angle varied little between younger and older asymptomatic Chinese adults; standard deviations were 2.3° in the sagittal plane and 1.0° in the coronal plane.
