AimTo observe the relationship between vascular lesions in the lower extremities and osteoporosis in elderly male people with type 2 diabetic mellitus.Methods148 elderly male patients with type 2 diabetic mellitus were enrolled.All patients underwent ultrasonography for both sides of artery of lower extremity.They also underwent dual-energy X-ray absorptiometry (DXA) examination to determine the bone mineral density (BMD)of the vertebra and the femoral head.According to a lower extremity vascular disease severity score, the patients were divided into control group, mild-moderate group and severe group.ResultsBMD was significantly different among three groups (P<0.05 or 0.01), the more severe lower extremity vascular disease, the lower the bone mineral density was.Only age, body mass index (BMI) and lower extremity vascular disease severity score correlated to osteoporosis by multiple regression analysis.ConclusionElderly male people with type 2 diabetic mellitus and vascular lesions in the lower extremities tend to have lower BMD, they may have increased prevalence of osteoporosis.
