Abstract: 

Background: Post-menopausal osteoporosis is one of the most important health problems. This condition frequently leads to bone fractures.
Objectives: To determine the effect of physical activities on bone mineral density (BMD) in post-menopausal women, regardless of any concomitant predisposing risk factors for osteoporosis.
Patients and Methods: BMDs of 174 consecutive post-menopausal women with a mean age of 59.7 years and a mean post-menopausal duration of 10.3 years were measured by dual energy X-ray absorptiometry (DEXA) technique. According to the reported T scores, risks of femur and lumbar vertebrae fractures were estimated. The correlation between physical activities,as well as other osteoporosis risk factors and the above-mentioned measured quantities was assessed.
Results: 68% of the individuals with no physical activities and 25% of those who had regular physical activities were in the osteoporotic range. The femoral fracture risk was significantly higher for those with no physical activities (50%) than those physically active subjects (19%).Moreover, risk of developing vertebral fracture was higher in the former group (74% vs. 35%). BMDs were significantly different between the two groups in general; (p<0.001) as well as between their subgroups without (n=129, p<0.001) and with (n=45, p<0.01) other risk factors for osteoporosis).
Conclusion: Physical activity has positive effects on BMD of post-menopausal women, resulting in their reduced likelihood of osteoporotic fractures, irrespective of presence or absence of other osteoporosis risk factors.
