title: Difference in bone acquisition among hormonally treated postmenopausal women with normal and low bone mass.
abstract: This prospective analysis was conducted to compare the effects of hormone treatments on bone mineral density (BMD) of the lumbar spine, hip, and distal forearm in postmenopausal women with normal BMD and those with low bone mass. Eighty healthy women were randomly assigned to receive a cyclic regimen of standard hormone replacement therapy (HRT) or currently used low-dose oral contraceptive (OC). Women were categorized as normal BMD and low bone mass according to the Thai reference database. The results revealed that women with low bone mass gained more BMD than those with normal BMD. The difference in mean per cent bone acquisition was obvious at the spine. In addition, further subset analysis into OC and HRT groups revealed higher effects of OC on BMD when compared to HRT.
