    Background: Osteoporosis is the most common metabolic bone disease and is a public health issue, particularly among the elderly, across the world. Given the significance of the disease in causing disability and, in particular, its dangers in old age, we aimed to examine osteoporosis and its determinant factors among the elderly.
   Methods: We conducted a cross sectional study in the province of Hamadan from September 2015 to March 2016 on all the elderly men and women covered by ‘Integrated and Comprehensive Elderly Care Program’. The data required for this study was collected through an aging health care checklist. To estimate the adjusted association of potential risk factors and other confounding variables of osteoporosis, multiple logistic regression was used at a significance level of 5%. 
   Results: In this cross sectional study, 1779 elderly men and women aged 6o years and over were studied. The prevalence of osteoporosis was 7.99% (95%CI:7.79-8.18), which was higher among women than in men (8.08% vs. 7.83%). The factors that raised the probability of osteoporosis were as follow: aging (OR= 1.05, 95% CI: 1.02-1.07, p<0.001), low education (OR=1.96, 95% CI:1.02-3.84, p=0.04), living in urban areas (OR=2.82, 95% CI:1.93-4.11, p<0.001), smoking (OR=2.39, 95% CI:1.42-4.04, p<0.001), and family history of osteoporosis (OR=1.95, 95% CI:1.07-3.54, p=0.03).
   Conclusion: Based on our results, aging, low education level, living in urban areas, being a cigarette smoker, and having a family history of osteoporosis were all predicting factors for osteoporosis among the elderly.
