Preservation of bone mineral density after 10 years of cross-sex hormonal treatment in trans persons

Background

Cross-sex hormonal treatment (CHT) in trans persons affects bone mineral density (BMD) on short term. However, long-term follow-up studies investigating the effects of CHT on BMD are lacking. [ view full abstract ]

Aim(s)

The aim of this study is to investigate the change in BMD after 10 years of CHT in both trans women and trans men. [ view full abstract ]

Main Outcome Measures

A retrospective cohort study was performed in adult trans women and trans men treated with cross-sex hormones at the VU University Medical Center Amsterdam (the Netherlands) since 1998. Persons were included for analyses if... [ view full abstract ]

Methods

Mean change in lumbar spine (LS) BMD expressed as T-score and age-matched Z-scores were analyzed and were stratified for age groups (18 to 30, 31 to 49, and ≥50 years), prior cross-sex hormone use, and the occurrence of... [ view full abstract ]

Results

71 trans women (mean age: 37 years, standard deviation (SD)±10 years) and 38 trans men (mean age: 33 years, SD±8 years) were included. In trans women, baseline mean T-score was -0.67 (SD±1.28) and mean Z-score -0.55... [ view full abstract ]

Conclusion

In both trans women and trans men, LS BMD was preserved after 8 to 12 years of CHT. However, as most persons were passed the age of peak bone mass achievement, the natural course of BMD is to decrease. Therefore, unchanged... [ view full abstract ]
