Effects of long-term and low-dose hormone replacement therapy on bone mineral density in postmenopausal women / 中国医学科学院学报

ABSTRACT

<p><b>OBJECTIVE</b>To observe the effects of long-term and low-dose hormone replacement therapy on bone mineral density (BMD), and the incidence of bone pain in postmenopausal women.</p><p><b>METHODS</b>Totally 141 postmenopausal women were selected from the medical staff of the Peking Union Medical College Hospital. Of them, 63 women treated with low-dose sex hormone for over 5 (5-32) years were divided into hormone replacement therapy (HRT) group, and 78 never receiving HRT were divided into control group. The BMD was measured by dual energy X-ray absorptiometry (DEXA) at lumbar spine, Ward's triangle, femoral neck, trochanter, and total hip, and the incidence of bone pain was inquired.</p><p><b>RESULTS</b>The BMD in the HRT group was 9.1% higher than that in the control group (P < 0.05). The incidence of bone pain was significantly lower in the HRT group (71.4%) than that in the control group (89.7%).</p><p><b>CONCLUSION</b>Long-term and low-dose hormone replacement therapy can reduce bone loss and the incidence of bone pain.</p>
