Trabecular bone score (TBS) is a newly developed parameter that can be derived from DXA scans of the spine and may reflect bone quality. This study provides TBS values in healthy postmenopausal women of African descent. INTRODUCTION: African American women have a lower risk for osteoporotic fractures as a result of higher bone density and better bone quality. We examined TBS in postmenopausal African American women since there are no previous reports in this population. METHODS: This was a study of healthy African American volunteers using baseline values prior to their participation in two vitamin D intervention studies conducted at an ambulatory research center of an academic health center. RESULTS: The study population consisted of 518 healthy postmenopausal African American women with a mean age of 66 years and a BMI of 30.1. Mean TBS (L1 to L4) was 1.300(.100 SD). Significant negative correlations were found between TBS and age and BMI. None of the biochemical variables were significantly correlated with TBS whereas the various bone density sites were correlated with TBS. CONCLUSION: TBS values for African American women are higher than those reported in the literature for white women and are inversely related to age and BMI.
