The longest study to assess bone mineral density of postmenopausal women has found lower bone loss than previously suggested.
In the study, which is published in the Journal of Bone and Mineral Research, followed 686 women in Finland for more than two decades. Postmenopausal bone loss was found to be constant and appeared to be approximately 10% over 25 years.
Taking hormone replacement therapy was linked with lower postmenopausal bone loss. Having a lower weight at the start of the study and gaining weight during follow-up were also linked with lower postmenopausal bone loss. Higher baseline bone mineral density was associated with a higher bone loss rate.
