(Reuters Health) – Older women who are under a lot of social strain may be more likely to develop brittle, fracture-prone bones after menopause than their counterparts with worry-free lives, a recent study suggests.

Researchers followed 11,020 postmenopausal women over six years, giving them periodic bone mineral density (BMD) tests and mood assessments. Participants rated their level of social strain, or negative interactions or relationships; their social support, or positive relationships; and social functioning, or limitations in social activity.

Each one-point increase in social strain scores was associated with 0.082% greater loss of BMD in the neck, 0.108% greater loss of BMD at the hip, and 0.069% greater loss of BMD in the lower spine, the study found.

“Fractures are a major societal burden affecting 1 in 2 older women, due to a variety of risk factors that lead to bone loss,” said Shawna Follis, lead author of the study and a researcher at the University of Arizona in Tucson.

“We found that high social stress is one risk factor that increases bone loss in aging women,” Follis said by email.

Much of the previous research into connections between osteoporosis and mental health has focused on whether impairment due to bone thinning or fractures might contribute to mood disorders like depression or anxiety, the researchers note.

In the current study, published July 9 online in Journal of Epidemiology & Community Health, high levels of social stress were associated with lower BMD even after researchers accounted for other factors that can impact bone health like age, education, chronic health problems, weight, smoking status, alcohol use, hormone therapy, age at menopause, physical activity, and fracture history.

Lower social functioning was tied to greater decreases in BMD in the neck and hip, the current study found. And low social support was associated with greater decreases in the neck.

The study doesn’t prove that social stressors directly impact bone mineral density, and researchers also didn’t look at the connection between various social stressors and falls or fractures. And it’s impossible to say from the study whether easing of social stress would have any effect on bone health.

Still, the results suggest that older women who do a better job of managing stress may have healthier bones and a lower fracture risk, said Dr. JoAnn Pinkerton, director of midlife health at the University of Virginia Health System in Charlottesville, Virginia and executive director emeritus of the North American Menopause Society.

“For women who are anxious or have higher social stress levels, mindfulness, cognitive therapy, self-calming strategies, yoga, counseling, access to community building, or, if needed, medications might decrease the psychosocial stress levels,” Pinkerton, who wasn’t involved in the study, said by email.

When women do have osteoporosis, there are still things they can do to prevent bones from becoming more brittle, Pinkerton added.

“Calcium, vitamin D and strength training may prevent further bone loss,” Pinkerton said. “Although many women are fearful of the side effects associated with medications for treating osteoporosis, the side effects are actually rare while fractures may be life changing.”
