Introduction: Osteoporosis is a huge problem in a developing country like India, it is a challenge to the present health resources and health facility. All over the world osteoporosis affects predominately the older population and more so the postmenopausal women. world health organization (WHO) defines up to 70% of women over the age of 80 to have osteoporosis. An algorithm is developed by WHO to estimate the 10-year fracture risk, which is to be used in the absence of bone mineral density. Malnutrition, smoking and alcoholism has a negative effect on the bone mineral density. The study was performed to evaluate the prevalence of osteoporosis in the urban postmenopausal women, the associated risk factors and the correlation of the disorder to the socioeconomic status. Material and Methods: Patientspersonal data like obstetrics, medical, menstrual, drug history, diet history and daily exposure to sunlight was collected in a performer which was designed for the study. Patients measurements like height, weight, BMI were recorded. BMD was recorded by performing dual-energy X-ray absorptiometry scan of the calceneum .Women were classified according to the WHO criteria. Results: The prevalence of the condition in the postmenopausal women was 21%. The mean age of the women was 50.6+/-5.6 years. Women with more than 3 children were associated with higher risk of osteoporosis. we found no significant associated with other medical conditions like diabetes and thyroid disorder. Lack of calcium intake and regular exercise was significantly associated with low BMI. Conclusion: Osteoporosis is a rapidly evolving condition, our study brings out the need of a large community based study, and the study of risk factors, so appropriate early measurements can be taken to interrupt the progression of the disease.
