Objectives: To determine the incidence of osteopenia and osteoporosis in the general population using broadband ultrasound bone densitometer. Material & methods: Heel bone mineral densitometry was performed in 1713 patients with the help of a broadband ultrasound bone densitometer. The broadband ultrasound attenuation (BUA) and ultrasonic speed of sound (SOS) of the calcaneus were measured to obtain quantitative ultrasound index (QUI), bone mineral density (BMD), T-score and Z-score. Fracture risk was also estimated. Results: Out of the 1713 patients, 685 (39.9%) were found to have osteopenia and 190 (11%) had osteoporosis. The incidence of osteopenia and osteoporosis in women (41.6% and 14.2% respectively) was found to be higher than the values in men (37.1% and 5.5% respectively). The incidence of osteopenia in the 31-39 years age group was found to be comparable in men and women (30.1% and 26.4% respectively). However, after the age of 40, the incidence of osteopenia and osteoporosis in women rose rapidly and was higher than that in men. Discussion: Bone formation is at it's peak in the mid 20's & continues till the age of 30-35 years after which the bone resorption gradually becomes faster than the formation of new bone. Bone density at any age would depend on peak bone density and the subsequent rate of bone loss. It is therefore important to determine the BMD in this age group to prevent osteoporosis & related complications later. Similarly it is important to subject women to assessment of BMD routinely after the age of 40 years as they are definitely at a higher risk of developing osteoporosis with advancing age.
