Comparison of the Bone Mineral Density and Bone Mineral Content between Pre and Post-Menopausal Women

Abstract

Background/Objectives: The aim of the study is to estimate the differences in bone mineral content, bone mineral density, T-score, Z score, and fracture risk before and after menopause.  

Methods/Statistical analysis: A total of 100 female including 45 pre menopause ( PM) and 55 post menopause(PoM) are participated in the study. BMDs of the lumbar vertebrae were assessed using the DXA technique. The mean age of the PM  group is   ( 40 ± 7.21 )  years, while the mean age of the (PoM) is    63 ± 7.24  years.

Findings: The bone mineral content ( BMC) values for the (PM)  group in the lumbar spine were 11.25, 13.89, 16.48, 18.86, and 60.47 g. Among (PoM) group, it was 10.71, 13.25, 16.05, 17.51, and 57.51 g respectively. And the BMD  values of the lumbar spine  were 0.94±0.12 g/cm2 vs. 0.88±0.20 g/cm2, 1.05±0.24 g/cm2 vs. 1.02±0.18 g/cm2, 1.15±0.22 vs. 1.10±0.21 g/cm2, 1.18±0.21 vs. 1.13±0.21 g/cm2 and 1.09±0.21 vs. 1.04±0.17 g/cm2 for  L1, L2, L3, L4, and total L1-L4.
