Determinants of Bone Mass Accrual in Transgender and Gender Diverse Youth Undergoing Pubertal Suppression Therapy.

GDTG youth undergoing GnRHa therapy appeared to have below-average aBMD velocity Z-scores. A lower BMI Z-score was a determinant of lower baseline height-adjusted aBMD and aBMD velocity Z-scores. Building on previous studies, our study highlights aBMD velocity as a novel technique for bone health surveillance in GDTG youth.
