Bone Density in Postmenopausal Women with or without Breast Arterial Calcification

BACKGROUND Identification of osteoporosis in women in order to prevent its related morbidity and mortality is considered a priority. Routine mammography is performed on all menopausal women as a screening tool. Determination of the relation between breast arterial calcification (BAC) on mammography and the bone density of this high-risk population could help us to determine those with osteoporosis. The aim of this study was to investigate the mentioned probable relation between BAC and osteoporosis. MATERIALS AND METHODS In this cross-sectional study, menopausal women referred for annual screening mammography were enrolled. According to the results of mammography, they were classified into two groups: menopausal women with and without calcification of breast arteries. The selected women were referred for bone mineral density (BMD) evaluation by dual-energy x-ray absorptiometry (DXA). The results of BMD were compared between the two studied groups. RESULTS In this study, BMD was measured in 43 and 45 menopausal women with and without BAC, respectively. After age adjustment the difference between BMD measurements were not statistically significantly different (P > 0.05). There was a significant negative correlation between age and lumbar (P = 0.002, r = -0.42) and hip bone (P = 0.000, r = -0.67) density in menopausal women with BAC. CONCLUSION The results of the current study indicated that there was no significant relationship between BAC and BMD in our studied population, but it seems that increasing age has an important role in both developing BAC and reducing BMD. For obtaining more conclusive results, further studies with larger sample sizes and considering the severity of BAC is recommended.
