Chronic renal disease changes both quality and quantity of bone through multi-factorial influences on bone metabolism, leading to osteopenia, osteoporosis and increased risk of fracture. The objectives of our present cross-sectional study were to determine the mean bone mineral density (BMD) and frequency of occurrence of osteoporosis and osteopenia in Saudi patients on hemodialysis (HD) for longer than 1 year. Forty-two male and 78 female patients with age between 20 and 50 years were enrolled in this study. The BMD of the lumbar vertebral spine (LV) and the neck of femur (FN) were measured in all patients. Data were analyzed using SPSS version 17.0 software and the level of significance was considered as P <0.05. The mean BMD in the LV (L2-L4) was 1.155 ± 0.026 g/cm 2 in male and 1.050 ± 0.025 g/cm 2 in female patients (P = 0.016). The mean BMD in the FN was 1.010 ± 0.023 g/cm 2 in male and 0.784 ± 0.020 g/cm 2 in female patients (P = 0.00). Based on the World Health Organization criteria, 73.8% of the male and 44.9% of the female patients in our study had normal BMD (P = 0.002); 16.7% male and 28.2% female patients had osteopenia (P = 0.14), while 9.5% male and 26.9% female patients had osteoporosis (P = 0.01). This study showed a marked decrease in mean BMD in the cortical bone (FN) compared with trabecular bone (LV) (P = 0.00) as well as in female patients on HD compared with male patients (P = 0.016 for LV and P = 0.00 for FN).
