Does prior oral contraceptive use improve bone mineral density in postmenopausal women?
Does prior oral contraceptive use improve bone mineral density in postmenopausal women?
Prior long-term oral contraceptive use is associated with higher bone mineral density in the lumbar spine and femoral neck in postmenopausal women.
Long-term oral contraceptive use was associated with higher postmenopausal spine and hip bone density; leaves open fracture prevention and needs prospective confirmation.
The long-term consequences of prior oral contraceptive use for bone mineral density were examined in 239 postmenopausal women, 35.1% of whom reported prior oral contraceptive use. Women who had used oral contraceptives for 6 or more years had significantly higher bone densities of the lumbar spine and femoral neck, but not of the ultradistal wrist or radius, than women who never used oral contraceptives.
