It has been reported that bone and muscle mass decrease with age. In the current study, we elucidated the characteristics of primary osteoporosis patients with decreasing muscle mass called as sarcopenia. One hundred and sixteen primary osteoporosis women patients over 65 years of age were included. We reviewed skeletal muscle mass index measured by bioelectrical impedance analysis, bone mineral density (BMD), the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) as low back pain score, SF-36 score as health-related quality of life (QoL) score, and the serum lever of albumin, lymphocyte count, and total cholesterol as nutrition status. We defined less than 5.7 kg/m2 of skeletal muscle mass index as sarcopenia. As the results, 32 patients (27.6%) were defined as sarcopenia in the current study. BMD on femoral neck and the serum level of albumin and lymphocyte count in sarcopenia group were significantly lower than those in non-sarcopenia group. Further, gait disturbance and psychological disorder scores of JOABPEQ and vitality, social function, and mental health scores of SF-36 in sarcopenia group were significantly worse than those in non-sarcopenia group. These findings indicated that sarcopenia patients might have low BMD of femoral neck, low nutrition status, low back pain score, and low health-related QoL.
