It is uncertain whether bone is routinely mobilised during pregnancy to provide calcium for the fetus and whether this is of a magnitude to cause osteoporosis. We have made sequential measurements of lumbar spine and hip bone mineral density (BMD) in 60 normal women before conception and then during the subsequent pregnancy out to one year after delivery. During pregnancy there was a significant fall...
Pregnancy is a common physiological event that could affect peak bone mass and the risk of developing osteoporosis later in life. There have been few longitudinal studies over a complete reproductive cycle of any size to show whether bone mineral density (BMD) changes. We have measured BMD by dual-energy X-ray absorptiometry in 46 normal women before conception and then again immediately after delivery...
