Bone mineral density in women above 40 years

The prevalence of osteoporosis in India is high and osteoporotic fractures are thought to occur early in Indian women. The aim was to study the prevalence of osteopenia and osteoporosis in women aged above 40 years. Women aged above 40 years attending the out patient department of this hospital were offered bone densitometry. A significant positive correlation was found between age and time since menopause and bone mineral density (BMD). Differences in the prevalence of osteoporosis were noted on the basis of socioeconomic strata. There was no statistically significant difference observed in BMD for many of the other accepted risk factors such as age at menarche, lactation, and exercise.
