Bad to the bone

Are hot flashes and other vasomotor symptoms an indication of adverse bone health? According to data coming out of the Study of Women’s Health Across the Nation, they might possibly be. Notably, while studies have examined the association between vasomotor symptoms and bone mineral density (BMD) previously, they have not followed women as they undergo the menopausal transition and rather, focused on women after they completed menopause.

Here are some of the study’s highlights:

• 2,213 women, ages 42 to 52, were included in the five year study. all had a uterus, were not using hormones, and had not yet entered menopause (i.e. still had their periods)
• Menopause stage and degree of vasomotor symptoms were assessed each year by questionnaire
• Bone mineral density was measured at the study’s start and each year. Dimensions were taken at the spine, hip, and pelvis

Study findings, which were published this past March in Menopause, showed that bone mineral density was lower in women with vasomotor symptoms compered to those without. What’s more, these effects varied depending in the stage of menopause. For example, women in pre- and early perimenopause with vasomotor symptoms had lower bone density measures in their pelvic areas, while women in postmenopause with vasomotor symptoms had lower BMD in their spine and hips. Overall, bone mineral density was consistently lower in women who experienced frequent vasomotor symptoms versus those who did not. In these cases, lower bone density was more evident in the lumbar spine in early peri- and postmenopause, and in the pelvis among early pre-menopausal women.

Whew! What does it all mean?

According to researchers, the findings suggest that vasomotor symptoms in menopause are linked to bone density deficits, which vary depending on the severity of symptoms and menopausal stage. This may help women and their practitioners devise more targeted strategies to protect bone health at appropriate times, and potentially encourage regular screening to prevent osteoporosis, fractures and related problems. The National Osteoporosis Foundation’s Bone Tool Kit includes information on calcium, vitamin D and exercise. Yoga Journal also has some great advice regarding safe and helpful postures.

Hot flashes and night sweats may be bad for the bones. But there are many positive steps we can take to protect them. Afterall, we only have one set. There’s no time like the present to take better care!

Sticks and stones

Remember that nursery rhyme from days gone by? It appears that vasomotor symptoms, including hot flashes and night sweats, may be as powerful in contributing to breakage as sticks and stones. Or at least in contributing to a lower bone mineral density (BMD). BMD reflects the strength of an individual’s bone, usually in relation to calcium content.

Researchers analyzed data for 2,213 women participating in the Study of Women’s Health Across the Nation. At the time of the study, all participants had their uteri intact, were not using hormones and were determined to be in pre- or perimenopause.  Menopausal stage and vasomotor symptoms were assessed via questionnaire and BMD was analyzed at yearly follow up visits.

The results, which are published in the March/April edition of Menopause, showed that BMD was consistently lower among women who had had vasomotor symptoms than among women who had not. These findings remained even after researchers adjusted for factors such as age, time within each menopausal stage, race/ethnicity, study site, and stage of menopause at the time that the study began.

Additionally, BMD was even lower among women who had more frequent night sweats and/or hot flashes than those who did not.

Notably, these effects varied by anatomic site and were most prevalent in the lumbar spine and hip in postmenopausal women, and at the femoral neck (pelvic region) among pre and perimenopausal women. More troubling, even women in the earliest stages of menopause also experiencing vasomotor symptoms  had lower bone mineral density than those who did not.

According to the National Osteoporosis Foundation, it is never too late to start a program aimed at halting bone loss and preventing future fractures. Because data are now suggesting that vasomotor symptoms may be linked to lower bone mineral density, it might be worthwhile to speak to your doctor to determine if you should undergo BMD testing. Other important steps include making sure that you are getting adequate amounts of vitamin D and calcium, engaging in weight-bearing activity, avoiding cigarettes and minimizing alcohol intake.

There is not time like the present to avoid potential pitfalls (no pun intended). Only you and your health practitioner can determine the proper steps to take. I’d also encourage you to read more about osteoporosis at the National Osteoporosis Website. The information is thorough and easy to navigate through.

Sticks and stones may break your bones. And hot flashes and night sweats might hurt you? Yikes!
