Worldwide 1 in 3 women over 50 years of age experience an osteoporotic fracture. Measuring bone mineral density is the most important tool in the diagnosis osteoporosis.To compare number of reproductive years, BMI and natural and surgical menopause with bone mineral density in post-menopausal women.Two hundred postmenopausal women were studied at the Department of Obstetrics &Gynaecology, King Georges Medical University, Lucknow from September 2015 to August 2016. A detailed questionnaire was filled which included details of demographic factors of the patient, BMI, Blood pressure, number of reproductive years, whether menopause was natural or surgical and personal history including history of exercise. BMD was measured in each woman at lumbar spine (L1-L4) by lunar Prodigy dual energy X Ray absorptiometry. Mean BMI showed a significant declining trend from normal to osteoporosis BMD status (p<0.001). Among overweight and obese patients majority had normal or osteopenic status (p<0.001). Prevalence of osteopenia and osteoporosis did not show a significant association with family history of fracture (p=0.835). Majority of women with normal BMD status used to climb stairs (60%) as compared to 50% of osteopenia and 41.5% of osteoporosis cases. However, this difference among groups was not significant (p=0.406). Among those having natural menopause the proportion of normal BMD, osteopenia and osteoporotic women was 1.1%, 38.3% and 60.6% as compared to 12%, 20% and 69% respectively among those having surgical menopause (p=0.002). No significant association of number of reproductive years with BMD was observed.BMI showed a highly significant association with the bone mineral density in the present study. The prevalence of osteopenia and osteoporoticwas higher in women with surgical menopause then natural menopause.
