Bone density and endometriosis

To establish whether there is evidence of low bone density in women with endometriosis, we compared bone density between 48 women with laparoscopically proven endometriosis and 48 age-matched normal controls. Bone density of the lumbar spine (L2-4), proximal femur (femoral neck, Ward's triangle, and trochanteric region), and total body were measured by dual energy roentgenogram absorptiometry. After adjusting for physical and lifestyle differences, bone density was not significantly different between the groups in any site. Bone density measurements were not related to the severity of endometriosis. These results do not confirm evidence of low bone density in women with endometriosis.
