“In conclusion, we report here for the first time that [menopausal hormone therapy] is associated with better preservation of bone microarchitecture, as assessed by [trabecular bone score],” the researchers wrote.1 “In addition to the well-established positive effect of [menopausal hormone therapy] on BMD, the bone microarchitecture preservation probably contributes to the antifracture efficacy. The protective effect of [menopausal hormone therapy] on BMD and [trabecular bone score] seems to persist after its withdrawal for at least 2 years.”

The researchers noted several study limitations, including self-reporting of data on the start and end of hormone therapy, as well as its route of administration.1 Moreover, the dose of estrogen per participant could not be determined.1

“Women at menopause should take note of this study, because its results can help optimize the use of menopausal hormone treatment in women at risk of osteoporosis,” Dr Papadakis said.5
