Abstract

OBJECTIVES
The purpose of this study was to evaluate the prevalence of osteoporosis in Gwangju women.
METHODS
A total of 1476 Gwangju women who attended Chosun University between December 2007 tand April 2010 were enrolled in this study. Bone mineral density (BMD) was determined for the lumbar spine, femoral neck, and total femur by dual-energy X-ray absorptiometry (DXA) using a GE-LUNA Progidy. We excluded women who had conditions that influence bone metabolism. BMD values were expressed in g/cm2 and the T-score. Osteoporosis was defined by a T-score < -2.5 SD for 20-29-year-old Korean adults.
RESULTS
The prevalence of osteoporosis in Gwangju women was 19 (12.8%), 19 (12.1%), 95 (18.8%), 158 (42.2%). 97 (74.0%), and 115 (71.7%) at the spine, 0 (0%), 5 (3.4%), 11 (2.2%), 55 (14.7%). 65 (49.6%), and 101 (63.3%) at the femoral neck, and 0 (0%), 3 (1.7%), 3 (0.6%), 11 (2.9%), 22 (16.8%), and 53 (33.3%) for the total femur of the groups 20~29, 30~39, 40~49, 50~59, 60~69, 70~88 years of age, respectively.
CONCLUSION
The criteria for osteoporosis are based on postmenopausal women, but premenopausal women who have low bone mineral density need to be examined for underlying diseases. Further, we must carefully establish a standard for BM for premenopausal women.
