Comparison of Osteoporosis Self Assessment Tool for Asian (OSTA) and Standard Assessment in Menopause Clinic, Chiang Mai

Objective: To compare osteoporosis self assessment tool for Asian (OSTA) with the standard measurement of bone mineral density (BMD) by dual energy x-rays absorptiometry (DXA) in identifying the prevalence of osteopenia and osteoporosis in Thai menopausal women who attended the Menopause Clinic, Faculty of Medicine, Chiang Mai University. Material and Method: The data was retrospectively collected from the medical records of women who had lumbar, femoral neck and radius BMD t-score measurement by DXA (Hologic®, QDR-4500C) between January 2004 and December 2005. The body weight and age of patients were calculated for the OSTA index score. The women with OSTA score <-1 and>-1 were classified as “moderate to high risk ” and “low risk ” for fracture, respectively. The BMD T-scores of <-1 and>-1 were classified as “osteopenia to osteoporosis ” and “normal” respectively. Results: Three hundred and fifteen menopausal women of the age of 45-87 years were included. The BMD T-scores assessment revealed that more than half of the subjects had osteopenia to osteoporosis (T-score <-1)
