Abstract:
Objective To explore the characteristics and its influential factors of bone mineral density (BMD) changes in partial androgen deficiency in aging male patients.Methods 186 aging male patients with partial androgen deficiency and 125 healthy persons were selected, and their BMD in the first to fourth lumber spine and the proximal left femur was measured with the dual-energy X BMD measuring instrument.The biochemical and bone metabolic markers and sexual hormones were collected, and the relationship between changes of BMD in the patients with partial androgen deficiency, age, BMI, sexual hormones and bone metabolic markers were observed by multivariate stepwise regression analysis.Results There was no significant difference in BMD at the lumbar spine between two groups( P ＞ 0.05 ), but BMD in PADAM group was lower than control groups at the hip[Neck: (0.831 ±0.136) g/cm2 vs (0.954 ±0.143) g/cm2,War's: (0.712 ± 0.127 ) g/cm2 vs ( 0.811 ± 0.149 ) g/cm2,Troch: ( 0.697 ± 0.124 ) g/cm2 vs ( 0.764 ±0.131 )g/cm2, P ＜ 0.05 )].The incidence of PADAM and control group with osteopenia were 48.9% and 36%, and the osteoporosis was 33.3% and 20.8%, respectively.The bone mineral density was positively correlated to BMI at the first to fourth lumber spine and the proximal left femur in the patients with PADAM and negatively correlated to age and serum level of androgen.Conclusion BMD in PADAM group was significantly decreased, and age and low BMI and androgen deficiency wwere the risk factors of low BMD in PADAM patients.
