Higher anxiety levels in postmenopausal women may put them at increased risk of fracture and should be considered when assessing a woman’s risk of osteoporosis as well. This is the conclusion of a study recently published in the journal Menopause that looked at the role of anxiety in bone health.1 Specifically, the study examined the link between anxiety levels and bone mineral density (BMD) and fracture risk among postmenopausal women.
Previous research has focused mainly on the psychological effects of osteoporosis and fracture on quality of life and anxiety levels, according to lead author of the study, Antonino Catalano, MD, PhD, Department of Clinical and Experimental Medicine, University Hospital of Messina, Messina, Italy. Dr. Catalano notes data from this research suggest that “in comparison with healthy women, osteoporotic women show a weakened quality of life and increased anxiety levels.”
What has not been looked at and what is new in this study is how anxiety levels may influence fracture risk. “We looked in the direction from anxiety levels to bone health [in postmenopausal women],” says Dr. Catalano.
The study found higher anxiety levels in postmenopausal women were linked to low bone mineral density and higher fracture risk, independent of other classical risk factors for osteoporosis, such as age, menopausal age, years since menopause and body mass index.
“Our findings suggest a possible new clinical risk factor for osteoporosis that could be measured to improve our ability to identify women at risk for fractures,” says Dr. Catalano.
The cross-sectional study included 192 white women recruited from a single institution in Messina, Italy. All women underwent evaluation to assess their anxiety level by completing 14 symptom-defining elements of anxiety included in the Hamilton Anxiety Rating Scale (HAMA). These elements include psychological symptoms of anxiety (e.g., tension, fear, sleep and memory issues, and depression), somatic symptoms of anxiety (e.g., aches and pains, ear or eye problems, chest tightness, gastrointestinal symptoms), as well as observed behaviors (e.g., fidgety or restlessness). Based on the results, women were grouped by level from mild (HAMA-1; n=87) to moderate (HAMA-2; n=48) to severe anxiety (HAMA-3; n=57).
All women also underwent evaluation to assess bone mineral density using standard imaging, as well as fracture risk using a computer-based algorithm (i.e., the Fracture Risk Assessment Tool) that calculates the 10-year probability of a major fracture.
The study found the women with the lowest levels of anxiety (HAMA-1) had a significantly lower 10-year probability of a major fracture compared with women who had the highest levels of anxiety (HAMA-3) (20.44% vs. 24.94%, respectively; P=0.03). Women with moderate levels of anxiety (HAMA-2) also had a significantly lower probability of fracture risk than the women with the highest anxiety levels (17.91% vs. 24.94%, respectively; P=0.002).
Women with the highest levels of anxiety also had significantly lower BMD than women with the lowest levels of anxiety. When looking at bone density of the lumbar spine and femoral neck, women with the highest anxiety levels had significantly lower T-score values than women at the lowest levels of anxiety (see Table 1).
