Osteoporosis is an acceleration of bone resorption that produces a lower total bone mass and density in the trabecular bone, being most common in older women. Bone mass is determined largely by genetic factors, as well as physical activity, diet, and hormonal status. The primary way to assess the potential for fragility fractures has always been to have a dual energy x-ray absorptiometry (DEXA) scan of the body. This is still an acceptable diagnostic measure, but not all populations can afford this. Some Hispanic women are at a disadvantage due to their low socioeconomic status and lack of resources. Little research exists to examine the bone health of this specific age or ethnic group of women. The purpose of this study was to determine the feasibility of conducting quantitative ultrasound (QUS) screening of uninsured Hispanic women to determine low bone mass in the calcaneus. The population included in the study was a convenience sample (n=69) of women who attended a free health clinic. Upon consent, participants placed their foot on the Achilles Bone Ultrasonometer to have their bone mass evaluated with ultrasound. A series of 2 to 3 measurements were taken for each patient to ensure reproducibility. The average of the measurements was used fo
