Objective: Osteoporosis is a substantial global public health issue. The objective of this study was to evaluate the risk variables associated with osteoporosis among patients seeking care at an outpatient menopausal clinic in a tertiary university hospital. Material and Methods: In this retrospective, cross-sectional study postmenopausal women who attended the outpatient menopause clinic of Başkent University Hospital between June 01, 2014, and August 31, 2015, were enrolled. Patients’ datasheets were reviewed and data including age, body mass index, parity, duration and age of menopause, history of smoking and oral contraceptive pills (OCPs) use, natural or surgical menopause, and calcium-containing food consumption were collected through a standardized questionnaire. Bone mineral density (BMD) was measured at the femur neck and lumbar spine by dual energy X-ray absorptiometry. Results: A total of 1,148 women with a mean age of 53.5±6.7 years, mean duration of menopause 7.1±6.2 years and mean age of menopause 46.3±5.1 years were identified. Of these, 235 (20.5%) were diagnosed as having osteoporosis. The average femur and lumbar T-values showed a decrease in normal weight patients compared to overweight, obese, and morbidly obese patients (F=22,337, p<0.001 and F=50,195, p<0.001, respectively). The mean femur T-values were higher in participants who used OCPs, regularly consumed a calcium-rich diet, and performed regular physical activity (p<0.05, p<0.01 and p<0.05). Positive correlations were noted between giving birth and femur T-values (r=0.065, p=0.027), between natural menopause and lumbar T-values (r=0.060, p=0.043), and between consuming a calcium-rich diet and femur T-values (r=0.087, p=0.003 and r=0.064, p=0.031, respectively). Conclusion: Using OCPs, lifelong physical activity, and a healthy diet rich in calcium are important factors for the prevention of low lumbar spine and femoral BMD and by implication, osteoporosis.
