Women reporting continuous or remote past hormone therapy (HT) use had less pronounced kyphosis than never-users by their mid-80s, suggesting a possible role for HT in the prevention of age-related hyperkyphosis. Researchers evaluated the cross-sectional association between Cobb angle of kyphosis from lateral spine radiographs and pattern of self-reported HT use during the prior 15-year period in 1,063 women (mean age 83.7±3.3 years; mean Cobb angle of 51.3±14.6°) from the Study of Osteoporotic Fractures. They found:
- 46% of women were characterized as never-users of HT, 24% as remote past users, 17% as intermittent users, and 12% as continuous users.
- In minimally adjusted models, the mean Cobb angle was 4.0° less in continuous HT users vs never-users; this association was attenuated to 2.8° in fully adjusted models.
- Remote past HT users had 3.0° less kyphosis compared with never-users in minimally adjusted models; attenuated to 2.8° less in fully adjusted models.
- Intermittent users did not differ from never-users in degree of kyphosis.
