Background: Osteoporosis is characterised by decrease in bone mineral density (mass/volume) of normally mineralized bone which makes it vulnerable to fragility fracture. Post menopausal females are prone to osteoporosis due to deficiency of estrogen following menopause. Due to paucity of litreature regarding bone mineral density distribution at various sites of body in post menopausal osteoporosis, we conducted a cross sectional study to evaluate the bone mineral density and the prevalence of primary postmenopausal osteoporosis at various sites.
Materials & Methods: Total 447 post menopausal females between age group 45-75years were recruited initially in our study. Out of 447 patients, only 225 patients satisfied our inclusion criteria and exclusion criteria were taken in the final study. All patients underwent BMD measurement through DEXA scan. BMD was measured at lumbar Spine, both hips, both femur and left forearm. DEXA scan is interpreted in terms of T score as per World Health Organisation (WHO) guidelines. The analysis was carried out by using SPSS 16.0 version
Results: Total prevalence of osteoporosis was 37.8% and maximum prevalence of osteoporosis was observed at spine (34%) followed by hip (22%) than at forearm (19%) and minimum at the femur.
Conclusion: There is high prevalence of post menopausal osteoporosis among Indian females and females are unaware of it because of its silent presentation, we need to create awareness regarding osteoporosis so that morbidity and mortality related to its can be avoided.
