Abstract:
Objective To explore the characteristics of bone mineral density (BMD) and the incidence of osteoporosis in partial androgen deficiency in aging male (PADAM) patients.Methods Fifty-six PADAM patients (PADAM group) and 51 healthy persons (control group) were selected according to their age and body mass index (BMI),and measured their BMD in the second to fourth lumber and the neck of femur with the dual-energy C X-ray BMD measuring instrument.MES-01S20 muscle function analyzer was used to determinate the distribution and mechanical properties of muscle.The biochemical and bone metabolic markers and sexual hormones were collected and observed by multivariate stepwise regression analysis.Results Compared with control group,BMD significantly decreased in the Ward triangle,femoral neck and big rotor (P ＜ 0.01 ) and no significant change in lumbar in PADAM group (P ＞ 0.05 ),and the fracture strength of femoral neck (FS) and the lower-limb muscular strength (MS) also significantly decreased (P ＜ 0.01 ).The incidence of osteopenia were 48.2% (27/56) and 35.3% ( 18/51 ),osteoporosis were 30.4% (17/56) and 21.6% ( 11/51 ) respectively in PADAM group and control group.There was significant difference between two groups (P＜0.05).The BMD was positively correlated to BMI at the first to fourth lumber and negatively correlated to age,positively correlated to BMI and serum level of andrusol at the proximal left femur in the patients with PADAM.Conclusion BMD and the resistance to fracture aresignificantly lower in PADAM patients,and aging lower BMI and androgen deficiency are the risk factors of low BMD in PADAM patients.There is the potential of osteoporotic fracture risk,and it is important to strengthening the prevention and treatment of fractures in elderly PADAM patients.
