Abstract
OBJECTIVE: To determine reference data for age-matched bone mineral density (BMD) of normal northeastern Thai women.
MATERIAL AND METHOD: 350 northeastern Thai women aged 20-70 years were prospectively studied. After interview, the subjects were examined for BMD of lumbar spines and proximal femur. Mean BMD of each group was determined for each skeletal site. Standard deviation (SD) of BMD in the peak group was calculated to determine BMD cutoff level for diagnosing osteoporosis.
RESULT: Peak average BMD of lumbar spines was at 40-45 years, whereas peak BMD of proximal femur was at 35-40 years. Mean value of peak BMD of lumbar spines and proximal femur was 1.226 and 1.035 g/cm2, respectively. According to T-score less than -2.5 SD criteria, osteoporosis of lumbar spines and proximal femur was considered when measured BMD was below 0.889 and 0.785 g/cm2, respectively.
CONCLUSION: Our study provided the BMD reference data for northeastern Thai women.
