We conducted a chart review of premenopausal women with low bone mineral density referred to the Metabolic Bone Clinic of Federal University of Paraná, to determine the outline of these patients regarding their risk factors and secondary causes of osteoporosis. Thirty-four women (1948 years old) were evaluated. Twenty nine (85.3%) patients presented a low bone mineral density (BMD) in lumbar spine, 8 (23.5%) had Z-score < -2.5 and 21 (61.8%) had Z-score between -1.0 and -2.5. Twenty patients (58.8%) had a low bone mass in total femur, 2 (6.2%) with Z-score < -2.5 and 18 (56.2%) with Z-score between -1.0 and -2.5. A secondary cause could be identified in 26 patients (76.5%). This study shows that DMO is important in premenopausal women with risk factors of low BMD because it leads to the best treatment option and follow-up.
