In transgender subjects, worse Bone Mineral Density (BMD) values were observed when compared to cisgender controls before initiating Gender-Affirming Hormonal Therapy (GAHT). The reasons have not yet been fully clarified. In this study we analyzed bone metabolism and body composition in a population of transgender people before initiating GAHT, and their possible correlation with endocrine profile, mental health, and lifestyle habits. Medical data, phosphocalcic metabolism and hormonal parameters, lumbar and femoral bone mineral density, body composition, strength and psychological well-being (by Patient Health Questionnaire-9-PHQ-9 and Perceived Stress Scale-PSS questionnaires), were collected in a sample of 32 transgender people before GAHT initiation and 32 cisgender controls. Assigned Female At Birth (AFAB) transgender people presented worse Z-score values at total hip and neck femoral sites (-0.52±0.94 vs 0.15±0.82, and -0.37±0.79 vs 0.19±0.66, p=0.04 respectively), while in Assigned Male At Birth (AMAB) transgender people also lumbar sites were compromised in comparison to cisgender controls. No significant difference in phospho-calcium metabolism (calcium, phosphate, PTH and vitamin D) or hormonal profile (Testosterone, estradiol, LH, FSH) was found between the transgender and the cisgender group. PHQ-9 (a questionnaire to screen for depression) scores were higher in the transgender population than cisgender controls (9.35±7.41 vs 4.08±3.14, p=0.03 in AFAB and 9.54±5.45 vs 4.46±3.59, p=0.02 in AMAB transgender people). Multiple regression analysis identified PSS (a tool to assess stress levels and identify which situations are perceived as stressful) score as an independent predictor of total femur BMD, explaining about 54% of the variance. Transgender people before GAHT have worse bone health than cisgender subjects. In particular, BMD was reduced at the hip and in AMAB even at lumbar site. The reduction in bone mass before GAHT seems independent by hormonal and phospho-calcic profile and associated mostly with psychological status. Further study will clarify the specific pathogenetic mechanisms involved in bone growth in transgender people. However, according to our evidences, the psychological stress might influence negatively lifestyle habits therefore being involved in reduced bone health. Early lifestyle and psychological interventions might so be beneficial also for bone health in the transgender population. Presentation: Saturday, June 17, 2023
