Osteoporosis, also known as the silent disease, occurs in women and men, and is associated with a loss of bone mass and increased risk of fracture. With aging there is a loss of bone mass and bone strength But does that mean that osteoporosis is a disease characteristic of aging, or that its incidence increases in old age? Data on prevalence of osteoporosis among women in India come from studies conducted in small groups spread across the country with 230 million Indians expected to be over the age of 50 years in 2015, 20% are osteoporotic. The DEXA scan & Qualitative ultrasound (QUS) methods are widely used for BMD analysis. Bone has a mechanically anisotropic structure, which ultrasound parameters are thought to reflect which is principle mechanism of QUS method. Methods: All 138 subjects between 20 – 70 years, 57 females & 91 males of north delhi region, in the study were examined by use of quantitative ultrasonography (QUS) method to evaluate their bone mineral density (BMD) at right calcaneus. Prevalence of osteoporosis or osteopenia in all males & females were calculated. Results: The results of present study were Indian females of north Delhi region depicts a high prevalence of 64.91% in 57 females and 62.63% in 91 male studied. Hence it was concluded that prevalence rate of osteoporosis as compared with previous studies has increased alarmingly to average 63% approximately in the studied population.
