Determination of Clinical Decision Rule for Estimation of Bone Mineral Density in Women

Objective: This study assessed the relative risk factors for osteoporosis in women referring to the Bone Densitometry Center during 2007, with the aim of designing a formula to estimate the severity of osteoporosis . Subjects and Methods: Data of outpatients (n = 1,047) who visited the Bone Densitometry Center of Chamran Hospital were gathered by administering a questionnaire to subjects before a dual-energy X-ray absorptiometry (DXA) densitometry test of the hip and vertebrae. Results: Of the 1,047 subjects, 764 (73%) were menopausal. The average ( 8 SD) age and weight were 54.5 8 10.3 and 69.5 8 10.8, respectively. The average ( 8 SD) T score of hip and lumbar spine were –1.88 8 1.08 and –1.04 8 1.05, respectively. After assessment, the precipitating factors of osteoporosis of the hip were age, menopause, duration of menopause, history of fracture, history and dosage of calcium supplementation, parity and duration of breastfeeding. Protective factors were weight, history Received: June 13, 2010 Accepted: March 3, 2011 Dr. Atousa Iranpour Asli Department of Clinical Excellence, Taleghani Hospital Shaheed Beheshti University of Medical Sciences Evin, Yaman Street, Tehran (Iran) Tel. +98 21 2243 2485 6, E-Mail ats.iranpour @ yahoo.com © 2011 S.
